- Abstract
Objectives: To investigate the long-term impact of multivessel coronary artery disease (MVD) on cause-specific mortality in patients with ST elevation myocardial infarction (STEMI) treated with reperfusion therapy.Methods and Results: Patients with STEMI (n = 395) treated with primary angioplasty or thrombolysis in the setting of a randomised clinical trial were enrolled in the study. Follow up was 8 (2) years. For patients who died all available records were reviewed to assess the specific cause of death. MVD was present in 57% of patients. Patients with MVD were older and more of them had diabetes and previous myocardial infarction. Compared with the non-MVD group, residual left ventricular ejection fraction was lower (45.9% v 49.6%, p = 0.001) and total mortality was higher in patients with MVD (32% v 19%, p = 0.002). After adjustment for potential confounders this association was not significant (hazard ratio 1.4, 95% confidence interval (CI) 0.9 to 2.2). When the specific cause of death was considered, sudden death was comparable between patients with and without MVD (10% v 8%, p = 0.49) but death caused by heart failure was significantly higher in patients with MVD (hazard ratio 7.4, 95% CI 1.7 to 32.2).Conclusion: Patients with STEMI and MVD have a higher long-term mortality than do patients with non-MVD. MVD is not an independent predictor of long-term total mortality or sudden death. However, MVD is a very strong and independent predictor of long-term death caused by heart failure.

- Abstract
Although the benefits of using the left internal mammary artery to bypass the left anterior descending artery (LAD) have been extensively ascertained, freedom from major cardiovascular events and survival after coronary artery bypass grafting (CABG) also correlate with the completeness of revascularisation. Hence, careful selection of the second-best graft conduit is crucial for CABG success. The more widespread use of saphenous vein grafts contrasts with the well-known long-term efficacy of multiple arterial grafting, which struggles to emerge as the procedure of choice due to concerns over increased technical difficulties and higher risk of postoperative complications. Conduit choice is at the discretion of the operator instead of being discussed by the heart team, where cardiologists are not usually engaged in such decisions due to a hypothetical lack of technical knowledge. Furthermore, according to the ESC/EACTS guidelines, traditional CABG remains the gold standard for multi-vessel coronary artery disease with complex LAD stenosis, but hybrid procedures using percutaneous coronary intervention for non-LAD targets could combine the best of two worlds. With the aim of raising the cardiologist's awareness of the surgical treatment options, we provide a comprehensive overview of the anatomical, functional and clinical aspects guiding the decision-making process in CABG strategy., Competing Interests: Conflict of interestG. Cuminetti, S. Gelsomino, S. Curello, R. Lorusso, J.G. Maessen and J.C.A. Hoorntje declare that they have no competing interest.

- Abstract
Objective: The superiority of drug-eluting stents (DES) over bare-metal stents (BMS) in patients with ST elevation myocardial infarction (STEMI) is well studied; however, randomised data in patients with non-ST elevation myocardial infarction (NSTEMI) are lacking. The objective of this study was to investigate whether stenting with everolimus-eluting stents (EES) safely reduces restenosis in patients with NSTEMI as compared to BMS., Methods: ELISA-3 patients were asked to participate in the angiographic substudy and were randomised to DE (Xience V) or BM (Vision) stenting (ELISA-3 group). The primary end point was minimal luminal diameter (MLD) at 9-month follow-up angiography. In addition, 296 patients with NSTEMI who were excluded or did not want to participate in the ELISA-3 trial (RELI group) were randomised to DE or BM stenting and underwent clinical follow-up only (major adverse cardiac events (MACE), stent thrombosis (ST)). A pooled analysis was performed to assess an effect on clinical outcome., Results: 178 of 540 ELISA-3 patients participated in the angiographic substudy. MLD at 9 months angiography was 2.37±0.63 mm (DES) versus 1.84±0.62 mm (BMS), p<0.001. Binary restenosis occurred in 1.9% in the DES group versus 16.7% in the BMS group (RR 0.11, 95% CI 0.02 to 0.84, p=0.007). In the pooled analysis, the incidence of MACE, target vessel revascularisation and ST at 2 years follow-up in the DES versus BMS group was 12.5% versus 16.0% (p=0.28), 4.0% versus 10.4% (p=0.009) and 1.3% versus 3.0% (p=0.34), respectively., Conclusions: In patients with NSTEMI, use of EES is safe and decreases both angiographic and clinical restenosis as compared to BMS http://www.isrctn.com/search?q=39230163., Trial Registration Number: 39230163; Post-results., Competing Interests: EAB received consulting fees from Merck Sharp and Dohme and Sanofi-Aventis.

- Abstract
Background: Cardiac shockwave therapy (CSWT) might improve symptoms and decrease ischaemia burden by stimulating collateral growth in chronic ischaemic myocardium. This prospective study was performed to evaluate the feasibility and safety of CSWT., Methods: We included 33 patients (mean age 70 ± 7 years, mean left ventricular ejection fraction 55 ± 12 %) with end-stage coronary artery disease, chronic angina pectoris and reversible ischaemia on myocardial scintigraphy. CSWT was applied to the ischaemic zones (3-7 spots/session, 100 impulses/spot, 0.09 mJ/mm(2)) in an echocardiography-guided and ECG-triggered fashion. The protocol included a total of 9 treatment sessions (3 treatment sessions within 1 week at baseline, and after 1 and 2 months). Clinical assessment was performed using exercise testing, angina score (CCS class), nitrate use, myocardial scintigraphy, and cardiac magnetic resonance (CMR) 1 and 4 months after the last treatment session., Results: One and 4 months after CSWT, sublingual nitrate use decreased from 10/week to 2/week (p < 0.01) and the angina symptoms diminished from CCS class III to CCS class II (p < 0.01). This clinical improvement was accompanied by an improved myocardial uptake on stress myocardial scintigraphy (54.2 ± 7.7 % to 56.4 ± 9.4 %, p = 0.016) and by increased exercise tolerance at 4-month follow-up (from 7.4 ± 2.8 to 8.8 ± 3.6 min p = 0.015). No clinically relevant side effects were observed., Conclusion: CSWT improved symptoms and reduced ischaemia burden in patients with end-stage coronary artery disease without relevant side effects. The study provides a solid basis for a randomised multicentre trial to establish CSWT as a new treatment option in end-stage coronary artery disease.

- Abstract
Background: There are controversial data regarding infarct-related artery only (IRA-PCI) revascularisation versus multivessel revascularisation (MV-PCI) in ST-elevation myocardial infarction (STEMI) patients with multivessel disease undergoing primary percutaneous coronary intervention (PCI). We performed a meta-analysis comparing outcome in same stage MV-PCI versus IRA-PCI in STEMI patients with multivessel disease., Methods: Systematic searches of studies comparing MV-PCI with IRA-PCI in the MEDLINE and the Cochrane Database of systematic reviews were conducted. A meta-analysis was performed of all available studies. Primary outcome was all-cause mortality. Secondary endpoints were re-infarction, revascularisation, bleeding and major adverse cardiac events (MACE)., Results: A total of 15 studies were identified with a total number of 35,975 patients. Mortality rate was significantly higher in the MV-PCI group compared with the IRA-PCI group, odds ratio (OR): 1.64 (1.46-1.85). Both the incidence of re-infarction and re-PCI were significantly lower in the MV-PCI group compared with the IRA-PCI group: OR 0.54 (0.34-0.88) and OR 0.67 (0.48-0.93), respectively. Bleeding complications occurred more often in the MV-PCI group as compared with the IRA-PCI group: OR 1.24 (1.08-1.42). Rates of MACE were comparable between the two groups., Conclusions: MV-PCI during the index of primary PCI in STEMI patients is associated with a higher mortality rate, a higher risk of bleeding complications, but lower risk of re-intervention and re-infarction and comparable rates of MACE.

- Abstract
Objective: Pre-hospital life-threatening ventricular tachycardia/fibrillation (VT/VF) is relatively common in the acute phase of ST-elevation myocardial infarction (STEMI). We evaluated the prognostic impact of out-of-hospital cardiac arrest (OHCA) due to VT/VF in non-selected patients with STEMI admitted for primary percutaneous coronary intervention (PCI)., Methods: Prospective hospital registry was used to collect data of consecutive STEMI patients admitted to our hospital between 2005 and 2010. Patients with OHCA were identified from this registry, and their medical records were reviewed., Results: During the study period, 4653 patients were admitted with STEMI. Data regarding OHCA due to VT/VF was available in 4643 patients (99.8%). A total of 326 patients (7.0%) had OHCA due to VT/VF. Patients with OHCA were younger (60.3 ± 11.8 vs. 64.1 ± 12.9 year, p<0.001), less often had diabetes (5.2% vs. 12.4%, p<0.001) but more often presented with signs of heart failure (Killip class >1:17.5% vs. 7.7%, p<0.001) and cardiogenic shock (29.6% vs. 2.5%, p<0.001). Coronary angiography was performed in 97.5% of the patients. Coronary angiography and primary PCI were performed equally in both groups. In patients with OHCA, the left main artery (2.3% vs. 1.0%, p=0.04) and LAD (49.2% vs. 41.2%, p=0.01) were more often the culprit artery. In-hospital mortality was significantly higher among patients with OHCA (13.80% vs. 3.4%, p<0.001). However, in patients who were discharged alive from the hospital, the one-year mortality and the combined incidence of death and appropriate ICD therapy were similar in patients with and without OHCA., Conclusion: In a large non-selected STEMI patient population admitted for primary PCI, OHCA due to VT/VF was associated with higher in-hospital mortality but did not affect the long-term prognosis., (© The European Society of Cardiology 2014.)

- Abstract
Background: The Zwolle Risk Score (ZRS) identifies ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PPCI) eligible for early discharge. We aimed to investigate whether baseline N-terminal pro-brain natriuretic peptide (NT-proBNP) is also able to identify these patients and could improve future risk strategies., Methods and Results: PPCI patients included in the Ongoing Tirofiban in Myocardial Infarction Evaluation (On-TIME) II study were candidates (N=861). We analyzed whether ZRS and baseline NT-proBNP predicted 30-day mortality and assessed the occurrence of major adverse cardiac events (MACEs) and major bleeding. Receiver operating characteristic curve analysis was used to assess discriminative accuracy for ZRS, NT-pro-BNP, and their combination. After multiple imputation, 845 patients were included. Both ZRS >3 (hazard ratio [HR]=9.42; P<0.001) and log NT-pro-BNP (HR=2.61; P<0.001) values were associated with 30-day mortality. On multivariate analysis, both the ZRS (HR=1.41; 95% confidence interval [CI]=1.27 to 1.56; P<0.001) and log NT-proBNP (HR=2.09; 95% CI=1.59 to 2.74; P<0.001) independently predicted death at 30 days. The area under the curve for 30-day mortality for combined ZRS/NT-proBNP was 0.94 (95% CI=0.90 to 0.99), with optimal predictive values of a ZRS ≥2 and a NT-proBNP value of ≥200 pg/mL. Using these cut-off values, 64% of the study population could be identified as very low risk with zero mortality at 30 days follow-up and low occurrence of MACEs and major bleeding between 48 hours and 10 days (1.3% and 0.6%, respectively)., Conclusion: Baseline NT-proBNP identifies a large group of low-risk patients who may be eligible for early (48- to 72-hour) discharge, whereas optimal predictive accuracy is reached by the combination of both baseline NT-proBNP and ZRS., (© 2014 The Authors.

- Abstract
Objectives: The aim was to investigate whether a strategy of direct drug-eluting stent (DES) implantation without pre-dilation is associated with a reduced incidence of restenosis compared with CS with pre-dilation or provisional stenting (PS)., Background: Previous studies were performed comparing direct stenting (DS) with conventional stenting (CS) after pre-dilation; however, none of these in the DES era. Therefore, the STRESSED (direct Stenting To reduce REStenosis in Stent Era with Drug elution) study was designed and carried out., Methods: A total of 600 patients with angina pectoris or recent myocardial infarction were randomized to a DS, CS, or PS strategy. The primary endpoint was the mean minimal lumen diameter at 9-month follow-up angiography. Secondary endpoints were clinical procedural success defined as angiographic success without in-hospital major adverse cardiac events (MACE), and MACE at 9-month and 2-year follow-up., Results: Stent implantation in the DS group was 98%, 99% in the CS group, and 77% in the PS group. Percutaneous coronary intervention success was 99% in all groups. The minimal lumen diameter at 9-month follow-up was 2.12 ± 0.58 mm (DS), 2.17 ± 0.67 mm (CS), and 1.99 ± 0.69 mm (PS), p = 0.556 for comparison of DS with CS, p = 0.073 for comparison of DS with PS. The absolute difference was -0.05 (DS to CS), 95% confidence interval: -0.19 to -0.09, p = 0.48 and 0.13 (DS to PS), confidence interval: -0.02 to -0.27, p = 0.087. Restenosis was found in 3.4% (DS), 6.7% (CS), and 11.5% (PS), p = 0.025. At 9-month and 2-year follow-up, MACE occurred in 6.8% and 11.5% (DS), 4.6% and 10.3% (CS), and 7.6% and 13.8% (PS) (p = 0.439 and 0.536), respectively., Conclusions: Direct DES implantation compared with conventional DES implantation did not reduce restenosis. Provisional stenting, however, was associated with a higher rate of restenosis. This did not translate into a difference in the rate of MACE.

- Abstract
Background: The aging congenital heart disease (CHD) population is prone to develop a variety of sequelae, including pulmonary arterial hypertension (PAH). Previous prevalence estimates are limited in applicability due to the use of tertiary centers, or database encoding only. We aimed to investigate the contemporary prevalence of PAH in adult CHD patients, using a nationwide population., Methods: A cross-sectional study was performed, using the population-based Dutch CONgenital CORvitia (CONCOR) registry. All patients born with a systemic-to-pulmonary shunt, thereby at risk of developing PAH, were identified. From this cohort, a random sample was obtained and carefully reviewed., Results: Of 12,624 registered adults with CHD alive in 2011, 5,487 (44%) were at risk of PAH. The random sample consisted of 1,814 patients (mean age 40 ± 15 years) and 135 PAH cases were observed. PAH prevalence in patients born with a systemic-to-pulmonary shunt was 7.4%. The prevalence of PAH after corrective cardiac surgery was remarkably high (5.7%). Furthermore, PAH prevalence increased with age, from 2.5% under 30 years until 35% in the eldest. PAH prevalence in the entire CHD population was 3.2%. Based on 3000 per million adult CHD patients in the general population, we can assume that PAH-CHD is present in 100 per million., Conclusions: This new approach using a nationwide CHD population reports a PAH prevalence of 3.2% in CHD patients, and 100 per million in the general adult population. Especially in patients after shunt closure and the elderly, physicians should be aware of PAH-CHD, to provide optimal therapeutic and clinical care., (Copyright © 2014 Elsevier Ireland Ltd.

- Abstract
It was the purpose of this study to assess the effect of thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) on reperfusion and clinical outcome in a real-world STEMI population. The decision to use TA (Export catheter, Medtronic) was at the discretion of the treating cardiologist. The primary endpoint was mortality at short (in-hospital) and long term (one year) follow-up. Secondary end points were post-PCI TIMI flow, residual ST deviation and enzymatic infarct size. Cox proportional hazard models (propensity-weighted) and logistic regression analysis were used to adjust for known covariates, associated with mortality. We performed a retrospective analysis of prospectively collected data on 2,552 consecutive PPCI-treated STEMI patients between 2007 and 2010. Use of TA increased from 6.9% in 2007 to 62.2% in 2010 (p<0.001). TA was performed in 899 patients (35.2%). In-hospital and one-year mortality rates were 3.0% and 6.0%, respectively, in the TA group and 3.5% and 7.6% in the no-TA group. After multivariate analysis, TA was not significantly associated with in-hospital mortality (adjusted odds ratio [OR]: 0.70; 95% confidence interval [CI]: 0.33-1.49, p=0.36) nor one year mortality (adjusted hazard ratio [HR]: 0.75, 95%CI: 0.47-1.20, p=0.23) or cardiac mortality (HR: 0.81; 95%CI: 0.45-1.46, p=0.49). After matching on the propensity score, the HR in the TA group for one year mortality was 0.70 (95%CI: 0.41-1.20, p=0.19) and for one-year cardiac mortality 0.70 (95%CI: 0.36-1.34, p=0.28). In conclusion, no significant relationship of TA with one of the secondary end points was found. The use of TA increased over the last years but clinical outcome was similar in both groups (TA vs no-TA) in this large cohort of real-world, unselected STEMI patients.

- Abstract
Aim: Poorer outcomes in women with ST-elevation myocardial infarction (STEMI) are often attributed to gender differences in baseline characteristics. However, these may be age dependent. We examined the importance of gender in separate age groups of patients with STEMI undergoing primary percutaneous coronary intervention (PPCI)., Methods and Results: Data of 6746 consecutive patients with STEMI admitted for PPCI between 1998 and 2008 in our hospital were evaluated. Age was stratified into two groups, <65 years (young group) and ≥65 years (elderly). Endpoints were enzymic infarct size as well as 30-day and 1 year mortality. We studied a total of 4991 (74.0%) men and 1755 (26.0%) women; 40% of women were <65 years and 60% of men were <65 years of age. In the elderly group (≥65 years), women had more frequently diabetes and hypertension while they smoked less frequently than men. Younger women smoked more often than similarly aged men and had more hypertension. At angiography, single-vessel disease and TIMI 3 flow before PPCI was more present in younger women than men, whereas these differences were not found in the older age group. Patient delay before admission was shorter in men at all ages, while women had lower creatine kinase levels. Younger women had a higher mortality after 30 days (HR 2.1, 95% CI 1.3-3.4) and at 1 year (HR 1.7, 95% CI 1.2-2.6), whereas in the older age group women mortality rates were higher at 30 days (HR 1.5, 95% CI 1.1-2.0) but not at 1 year (HR 1.2, 95% CI 0.9-1.5). After multivariate analysis, 1-year mortality remained significantly higher in women at younger age (HR 1.7, 95% CI 1.1-2.5). Patient delay before admission was shorter in men in both age groups. Creatine kinase levels were in both age groups higher in men., Conclusions: Differences in mortality between men and women with STEMI treated with PPCI are age dependent. Although young women have less obstructive coronary artery disease and more often TIMI 3 flow before PCI (suggesting a lower risk), survival was worse compared to similarly aged men. Women had a longer patient delay compared to men, but this was not related to gender-specific mortality.

- Abstract
Background: Both acute hyperglycemia as diabetes results in an impaired prognosis in ST-elevation myocardial infarction (STEMI) patients. It is unknown whether there is a different prevalence of diabetes and acute hyperglycemia in men and women within age-groups., Methods: Between 2004 and 2010, 4640 consecutive patients (28% women) with STEMI, were referred for primary PCI. Patients were stratified into two age groups, < 65 years (2447 patients) and ≥65 years (2193 patients). Separate analyses were performed in 3901 patients without diabetes. Diabetes was defined as known diabetes or HbA1c ≥6.5 mmol/l at admission., Results: The prevalence of diabetes was comparable between women and men in the younger age group (14% vs 12%, p = 0.52), whereas in the older age group diabetes was more prevalent in women (25% vs 17% p < 0.001). In patients without diabetes, admission glucose was comparable between both genders in younger patients (8.1 ± 2.0 mmol/l vs 8.0 ± 2.2 mmol/l p = 0.36), but in older patients admission glucose was higher in women than in men (8.7 ± 2.1 mmol/l vs 8.4 ± 2.1 mmol/l p = 0.028). After multivariable analyses, the occurrence of increased admission glucose was comparable between men and women in the younger age group (OR 1.1, 95%CI 0.9-1.5), but increased in women in the older age group (OR 1.3, 95% CI 1.1-1.7). Both diabetes and hyperglycemia were associated with a higher one-year mortality in both men and women., Conclusions: The differences between men and women in hyperglycemia and diabetes in patients with STEMI are age dependent and can only be observed in older patients. This may have implications for medical treatment and should be investigated further.

- Abstract
Background: Myocardial necrosis is a time-dependent event. Nevertheless, clinical studies on association between ischemic time and left ventricle function showed inconsistent findings. Aim of current study is to evaluate the association between ischemic time and the post-infarction left ventricular function in ST-elevation myocardial infarction treated with primary PCI., Methods: In 2529 patients treated with primary PCI, left ventricular ejection fraction (LVEF) was measured before discharge (median day 4) by radionuclide ventriculography or by echocardiography if patients had atrial fibrillation. Ischemic time was calculated from symptom onset to first balloon inflation., Results: The correlation between ischemic time as continuous variable and LVEF was significant but weak (P=0.002, r=-0.062). The LVEF of patients in ischemic time intervals of >6, >3-6, and ≤3 h was 45.1±11.7%, 44.6±11.9%, and 43.2±12.2%, respectively (P=0.029). Adjusted odds ratio of the ischemic time intervals for LVEF<40% was 1.14 (95% CI 1.00-1.30). TIMI flow 0 before and TIMI flow 3 after PCI were related with both longer ischemic time and low LVEF., Conclusion: Ischemic time was associated with post infarction LVEF in patients treated with primary PCI, although this association was weak. Initial TIMI flow and post-PCI TIMI flow played important role in impact of the ischemic time on the LVEF., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Background: There are conflicting data regarding optimal treatment of non-culprit lesions detected during primary percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) and multi-vessel disease (MVD). We aimed to investigate whether ischaemia-driven early invasive treatment improves the long-term outcome and prevents major adverse cardiac events (MACE)., Methods: 121 patients with at least one non-culprit lesion were randomised in a 2:1 manner, 80 were randomised to early fractional flow reserve (FFR)-guided PCI (invasive group), and 41 to medical treatment (conservative group). The primary endpoint was MACE at 3 years., Results: Three-year follow-up was available in 119 patients (98.3 %). There was no significant difference in all-cause mortality between the invasive and conservative strategy, 4 patients (3.4 %) died, all in the invasive group (P = 0.29). Re-infarction occurred in 14 patients (11.8 %) in the invasive group versus none in the conservative group (p = 0.002). Re-PCI was performed in 7 patients (8.9 %) in the invasive group and in 13 patients (32.5 %) in the conservative group (P = 0.001). There was no difference in MACE between these two strategies (35.4 vs 35.0 %, p = 0.96)., Conclusions: In STEMI patients with MVD, early FFR-guided additional revascularisation of the non-culprit lesion did not reduce MACE at three-year follow-up compared with a more conservative strategy. The rate of MACE in the invasive group was predominantly driven by death and re-infarction, whereas in the conservative group the rate of MACE was only driven by repeat interventions.

- Abstract
Aim: In patients with ST-segment elevation myocardial infarction (STEMI), it is uncertain whether atrial fibrillation has prognostic implications. There may be a difference between atrial fibrillation before and after reperfusion therapy., Methods and Results: In patients with STEMI treated with primary percutaneous coronary intervention (PCI), ECGs were analysed before and after primary PCI. Of the 1623 patients with electrocardiographic data before primary PCI, 53 patients (3.3%) had atrial fibrillation. Patients with atrial fibrillation were older, were more often female, and less often had anterior MI location. Of the 1728 patients with electrocardiographic data after primary PCI, 52 patients (3.0%) had atrial fibrillation. Atrial fibrillation was more common in older patients and in those with Killip class >1. Also patients with occlusion of the right coronary artery or TIMI flow 0 before primary PCI more commonly had AF after the procedure. Not successful reperfusion was also associated with a higher incidence of AF after primary PCI. Although both atrial fibrillation before and after primary PCI were associated with increased mortality, multivariable analyses, adjusting for differences in age, gender and Killip class on admission, revealed that atrial fibrillation after PCI (OR 3.69, 95% CI 1.87-7.29) but not before PCI (OR 1.86, 95% CI 0.89-3.90) was independent and statistically significantly associated with long-term mortality., Conclusion: In patients with STEMI, atrial fibrillation after but not before primary PCI has independent prognostic implications. Possibly, atrial fibrillation after the PCI is a symptom of failed reperfusion and a sign of heart failure.

- Abstract
This is a prospective, observational study performed in all consecutive ST-elevation myocardial infarction (STEMI) patients who had activated clotting time (ACT) measurement on arrival in the cathlab before coronary angiography. We studied the therapeutic effects of a pre-hospital fixed heparin bolus dose in consecutive patients with STEMI. A total of 1,533 patients received pre-hospital administration of aspirin, high dose clopidogrel (600 mg) and a fixed bolus dose of 5,000 IU unfractionated heparin (UFH), according to the national ambulance protocols. Some patients were also treated with glycoprotein IIb/IIIa inhibitors (GPI) in the ambulance. A therapeutic ACT range was defined according to the ESC guidelines as 200-250 seconds when patients had GPI pre-treatment and 250-350 seconds when no GPI pre-treatment. Of the 1,533 patients, 216 patients (14.1%) had an ACT within the therapeutic range, 82.3% of the patients had a too low ACT, whereas 3.5% of the patients had a too high ACT. After multivariable analysis, the only independent predictor of a too low ACT was increasing weight (odds ratio 1.02/kg, 95% confidence interval 1.01-1.03, p=0.001). Patients with a too low ACT had less often an open infarct related vessel (initial TIMI flow 2,3) as compared to patients with an ACT in range (36.5% vs. 45.9%, p=0.013). In only a minority of patients with STEMI, pre-hospital treatment with a fixed bolus dose UFH is within the therapeutic ACT range. Increased weight is an independent determinant of a too low ACT. We strongly recommend weight adjusted administration of UFH in the ambulance.

- Abstract
Background: We evaluated the effect of prehospital triage (PHT) in the ambulance on infarct size and clinical outcome and studied its relationship to the distance of patient's residence to the nearest percutaneous coronary intervention (PCI) center., Methods: All consecutive ST-segment elevation myocardial infarction patients who were transported to the Isala klinieken from 1998 to 2008 were registered in a dedicated database. Of these, 2,288 (45%) were referred via a spoke center and 2.840 (55%) via PHT., Results: PHT patients were more often treated within 3 hours after symptom onset (46.2% vs 26.8%, P < .001), more often had a post-procedural thrombolysis in myocardial infarction (TIMI) 3 flow (93.0% vs 89.7%, P < .001) had a smaller infarct size (peak creatine kinase 2,188 ± 2,187 vs 2,575 ± 2,259 IU/L, P < .001) and had a lower 1-year mortality (4.9% vs 7.0%, P = .002). After multivariate analysis, PHT was independently associated with ischemic time less than 3 hours (OR 2.45, 95% CI 2.13-2.83), a peak creatine kinase less than the median value (OR 1.19, 95% CI 1.04-1.36) and a lower 1-year mortality (OR 0.67, 95% CI 0.50-0.91). The observed differences between PHT patients and the spoke group were more pronounced in the subgroup of patients living >38 km from the PCI center., Conclusion: PHT in the ambulance is associated with a shorter time to treatment, a smaller infarct size and a more favorable clinical outcome, especially with longer distance from the patient's residence to the nearest PCI center. Therefore, PHT in the ambulance may reduce the negative effect of living at a longer distance from the PCI center., (Copyright © 2011 Mosby, Inc. All rights reserved.)

- Abstract
Background: Despite the proven benefit of glycoprotein IIb/IIIa blockers in patients with acute ST-segment elevation myocardial infarction (STEMI), there is still debate on the timing of administration of these drugs and whether all or only a selection of patients should be treated. We evaluated the effect of routine upfront versus provisional use of high-dose tirofiban (HDT) in a large real-world population of non-selected STEMI patients., Methods: Consecutive STEMI patients were registered in a single-centre dedicated database. Patients with upfront HDT therapy before first balloon inflation were compared with patients who received the drug on a provisional basis, after first balloon inflation. Initial TIMI flow of the infarct-related vessel and enzymatic infarct size and 30-day clinical outcome were assessed., Results: Out of 2679 primary PCI patients HDT was given upfront in 885 (33.0%) and provisionally in 812 (45.3%). Upfront as compared with provisional HDT showed higher initial patency (22.3 vs. 17.9%, p=0.006), smaller infarct size (1401 IU/l (IQR 609 to 2948) vs. 1620 (753 to 3132), p=0.03) and a lower incidence of death or recurrent MI at 30 days (3.3 vs. 5.1%, p=0.04) without an increase in TIMI bleeding (p=0.24). Upfront HDT independently predicted initial patency (odds ratio (OR) 1.47, 95% confidence interval (CI) 1.15 to 1.88, p=0.02), enzymatic infarct size (OR 0.70, 95% CI 0.56 to 0.86, p=0.001) and 30-day death or recurrent MI (OR 0.59, 95% CI 0.37 to 0.95, p=0.03)., Conclusion: Our findings support the use of upfront potent antiplatelet and antithrombotic therapy in STEMI patients and encourage further clinical investigations in this field.

- Abstract
Aims: Although closure devices may be comfortable for patients, the clinical benefits in patients with moderate-to-high risk of bleeding are not yet clear. We compared a closure device with manual compression in moderate- to high-risk bleeding patients undergoing percutaneous coronary intervention (PCI)., Methods and Results: A randomized study was performed to compare a closure device (Angio-Seal, St. Jude Medical, Inc.) with manual compression in 627 patients treated with aspirin, clopidogrel, a glycoprotein IIb/IIIa inhibitor and heparin during PCI. The primary endpoint was the inhospital combined incidence of: 1) severe hematoma > 5 cm at the puncture site or groin bleeding resulting in prolonged hospital stay, transfusion and/or surgical intervention at the puncture site; 2) arteriovenous fistula formation and/or surgical intervention at the puncture site. A total of 313 patients (49.9%) were randomized to the closure device and 314 patients (50.1%) to manual compression. The combined primary endpoint was 2.6% in the closure device group compared to 4.5% in the manual compression group (p = 0.195). In the predefined subgroup of patients with a history of hypertension, however, the combined primary endpoint (0.8% vs. 7.2%; p = 0.008) was significantly reduced after use of the closure device., Conclusion: This trial did not show the superiority of using a closure device over manual compression in patients treated with triple antiplatelet therapy who underwent PCI. The fact that patients with a history of hypertension had a benefit from a closure device merits further investigation.

- Abstract
Background. In patients with unstable angina or non-ST-elevation acute coronary syndrome (NSTE-ACS) who are eligible for PCI, routine stenting is the recommended treatment strategy, based on the opinion of experts. Provisional stenting may provide a viable alternative by retaining the early benefits of stenting without its potential late hazards.Method. Patients with NSTE-ACS were randomised to provisional or routine stenting after coronary angiography. Patients were followed for up to ten years. The occurrence of major adverse cardiac events (MACE) was recorded.Results. 237 consecutive patients with NSTE-ACS were randomly assigned to routine stenting (n=116) or provisional stenting (n=121). No difference in the incidence of MACE at 30 days was observed. At six months, angiographic restenosis was lower in the routine stenting group (41 vs. 20%, p=0.02), paralleled by more MACE in the provisional stenting group at one year (40.5 vs. 27.6%, p=0.036). At complete follow-up the difference in MACE was not significant (61.2 vs. 50%, p=0.084) because of relatively more target lesion revascularisations in the routine stent group. There was no difference in the incidence of very late stent thrombosis (1.7 vs. 3.4%, p=0.439). The only independent predictor of MACE was beta-blocker use (RR 0.62 [0.431; 0.892] p=0.010).Conclusion. In selective patients with NSTE-ACS, routine stenting was more beneficial than provisional stenting for a period of up to five years, driven by a reduction in repeat revascularisation procedures. After this period, the benefit was no longer significant. Beta-blocker use was the only independent predictor of MACE throughout the complete follow-up period. (Neth Heart J 2010;18:307-13.).

- Abstract
Objectives: To assess the influence of age as an independent factor determining the prognosis and outcome of patients with acute myocardial infarction (AMI) treated using primary percutaneous coronary intervention (PCI)., Design: A retrospective analysis from a dedicated database., Setting: A high-volume interventional cardiology center in the Netherlands., Participants: Four thousand nine hundred thirty-three consecutive patients with AMI., Measurements: Baseline characteristics and clinical outcomes after 30 days and 1 year were compared according to age categorized in three groups: younger than 65, 65 to 74, and 75 and older. A more-detailed analysis was performed with six age groups, from younger than 40 to 80 and older., Results: Of the 4,933 consecutive patients with AMI treated with PCI between 1992 and 2004, 643 were aged 75 and older. Multivariate analysis revealed that patients aged 65 to 75 had a greater risk of 1-year mortality than those younger than 65 (adjusted odds ratio (AOR)=1.57, 95% confidence interval (CI)=1.15-2.16) and that those aged 75 and older had a greater risk of 1-year mortality than those younger than 65 (AOR=3.03, 95% CI=2.14-4.29)., Conclusion: In this retrospective analysis, older age was independently associated with greater mortality after PCI for AMI. Patients aged 65 and older had a higher risk of mortality than younger patients, and those aged 75 and older had the highest risk of mortality.

- Abstract
Aims: To investigate incidence, predictors and prognosis of bleeding in ST elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention (PCI)., Methods and Results: A large scale, prospective, observational study was performed between 1991 and 2004 in a single teaching hospital in The Netherlands including all consecutive STEMI patients who underwent primary PCI. The independent association between both major and minor bleeding and one year mortality was evaluated using Cox proportional hazard models. A total of 5,030 patients were included, of whom 109 patients (2%) had cardiac surgery within 48 hours. Data on bleeding <48 hours were available in 4,717 patients (96%). Of these, 80 (1.6%) had major bleeding, whereas minor bleeding was observed in 266 patients (5.6%). Independent predictors of minor bleeding were advanced age, multivessel disease, Killip class > or = 2 on admission, anterior MI location and TIMI 0 flow before PCI. Killip class > or = 2 on admission was an independent predictor of major bleeding. Major bleeding (HR 3.5 [95% CI 2.3-5.4]) was associated with an increased risk of death at one year., Conclusions: After primary PCI, the incidence of major bleeding is less than 2%. Although relatively infrequent, major bleeding complications are strongly and independently related to short- and midterm mortality.

- Abstract
Aims: Evidence regarding the optimal treatment of non-culprit lesions detected during primary PCI is lacking. Our aim was to investigate whether early invasive treatment improves left ventricular ejection fraction (EF) and prevents major adverse cardiac events (MACE)., Methods and Results: Of 121 patients with at least one non-culprit lesion, 80 were randomised to early FFRguided PCI (invasive group), and 41 to medical treatment (conservative group). Primary endpoint was EF at six months, secondary endpoints included MACE. In the invasive group, early angiography was performed 7.5 days (5-20) after primary PCI. Forty percent of the non-culprit lesions did not show haemodynamic significance (FFR > 0.75). Subsequent PCI of at least one non-culprit lesion was performed in 52%, PCI without preceding FFR was performed in 8% and elective CABG was done in 4%. No in-hospital events occurred in the conservative group. After six months, EF was comparable (59+/-9% vs. 57+/-9%, p=0.362), and there was no difference in MACE between invasively and conservatively treated patients (21 vs. 22%, p=0.929)., Conclusions: An invasive strategy towards non-culprit lesions does not lead to an increase in EF or a reduction in MACE. The functional stenosis severity of non-culprit lesions is frequently overestimated.

- Abstract
Two young patients, a 23-year-old man and a 30-year-old woman, without any risk factors for coronary artery disease, apart from the woman being a smoker, were admitted to our hospital because of acute myocardial infarction (MI) due to spontaneous dissection of a coronary artery (SDCA). The first patient developed acute chest pain while playing soccer. The second patient had unspecific chest pain in the preceding four weeks and was admitted after successful resuscitation with ventricular fibrillation. Both patients were treated with primary percutaneous coronary intervention. SDCA is a rare cause of MI and sudden cardiac death with an indistinguishable presentation due to plaque rupture. The majority of cases occur in young women. It is associated with various pathophysiological mechanisms and can manifest during pregnancy, in the postpartum period, in collagen diseases, cocaine abuse, severe hypertension, smoking, oral contraceptives, heavy exercise, or vasospasm. Treatment, pharmacological or with revascularization, is based on the severity of the dissection. Patients who survive the acute phase have good long-term prognoses.

- Abstract
Background: No randomized comparisons are yet available evaluating the effect of pre-hospital high dose tirofiban on the incidence of early stent thrombosis after primary percutaneous coronary intervention (PCI)., Objectives: The aim of this analysis was to evaluate whether routine pre-hospital administration of high-dose tirofiban in ST-segment elevation myocardial infarction (STEMI) decreases the incidence of early stent thrombosis after primary PCI., Patients/methods: The Ongoing Tirofiban in Myocardial Evaluation (On-TIME) 2 trial was a prospective multicenter study of consecutive STEMI patients referred for primary PCI in which patients were randomized to pre-hospital no high-dose tirofiban/placebo. We examined the incidence of Academic Research Consortium definite and probable early stent thrombosis and determined predictors and outcome of early stent thrombosis., Results: Primary PCI was performed in 1203 out of 1398 patients (86.1%). In 1073 patients (89.2%) a coronary stent was placed. Early stent thrombosis occurred in 39 patients (3.6%). Pre-hospital initiation of high-dose tirofiban significantly reduced early stent thrombosis (2.1% vs. 5.2%, P = 0.006) and was associated with a lower incidence of urgent repeat PCI (1.9% vs. 5.2%, P = 0.005). Early stent thrombosis, as well as pre-hospital initiation of high-dose tirofiban, was independently associated with 30-day mortality., Conclusions: Pre-hospital initiation of high-dose tirofiban reduces the 30-day incidence of stent thrombosis in STEMI patients treated with primary PCI and stenting. Early stent thrombosis and pre-hospital initiation of high-dose tirofiban were independent predictors of 30-day mortality.

- Abstract
Compared with bare metal stents, sirolimus- and paclitaxel-eluting stents (SESs and PESs, respectively) have been shown to improve angiographic and clinical outcomes after percutaneous coronary intervention (PCI) in elective patients and those with ST-elevation myocardial infarction (STEMI). The aim of the present study was to compare SESs with PESs in patients with STEMI undergoing primary PCI. Patients with STEMI were randomized 1:1 to receive SESs (n = 196) or PESs (n = 201). The primary end point was late lumen loss at 9-month follow-up by quantitative coronary angiography. Secondary end points were major adverse cardiac clinical events (death, reinfarction, target vessel revascularization) at 1 month and 9 and 12 months. Three hundred ninety-seven patients with STEMI were randomized. The 2 groups had comparable baseline clinical and angiographic characteristics. Mortality was low, 1.5% after 30 days, 2.3% after 9 months, and 3.1% after 1 year. There was no difference in any clinical outcome at any follow-up period between the 2 treatment groups. Follow-up angiography was completed in 272 of 397 patients (69%). Mean +/- SD in-stent late loss was 0.01 +/- 0.42 mm in the SES group versus 0.21 +/- 0.50 mm in the PES group (difference -0.20 mm, p = 0.001). In conclusion, in patients with STEMI, primary PCI with SESs results in less late loss compared with PESs. However, these benefits did not translate into a significant decrease in major adverse cardiac events at 1-year follow-up.

- Abstract
Background: More than 10 years ago, survival benefit of primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) was demonstrated in several randomized trials. Since then, primary PCI has been implemented in routine daily practice and is in the guidelines of the preferred reperfusion therapy for patients with STEMI. We aimed to assess time-dependent changes in baseline characteristics, concomitant treatment and prognosis in patients with STEMI treated with primary PCI., Methods: Individual patient data from all 4732 patients admitted for primary PCI for STEMI between 1994 and 2004 in our hospital were recorded. Patient characteristics, concomitant treatment and one-year outcome were evaluated., Results: During the 11-year period, mean age and proportion of female were increasing, whereas door to balloon time decreased. Stent implantation rates increased from 2% to 84%. At discharge, prescription of aspirin, beta-blockers, statins, and ADP receptor blockers increased significantly. From 1994 to 2004, hospital stay shortened from 10.4 to 4.5 days p<0.001. Hospital and one-year mortality decreased, from 6.7% to 1.4% and 9% to 4.9% (both p<0.001), respectively., Conclusions: Between 1994 and 2004, utilization of stents and recommended pharmacotherapies increased remarkably. Hospital stay and both hospital and one-year mortality decreased significantly.

- Abstract
Background: Mounting interest has emerged on the role of distal embolization as a major explanation of poor myocardial perfusion among patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary angioplasty. The aim of the current study was to evaluate the relationship between vessel size, distal embolization, myocardial perfusion and clinical outcome in patients with STEMI treated by primary angioplasty., Methods: Our population is represented by 1969 patients with STEMI undergoing primary stenting from 1997 to 2002. All clinical, angiographic, and follow-up data were prospectively collected., Results: Vessel size was linearly associated with gender, diabetes, anterior infarction location, shorter time-delay, the rate of stenting and glycoprotein IIb-IIIa inhibitors. Small vessel size was associated with poor perfusion, despite lower rates of distal embolization. These data were confirmed after correction for confounding factors. The higher risk profile and poor myocardial perfusion contribute to explain the worse outcome observed in patients with smaller vessel size., Conclusions: This study shows that in patients undergoing primary angioplasty for STEMI, small vessel size is associated with poor myocardial perfusion, despite less distal embolization, that contributes to explain the worse outcome observed among patients with small infarct related arteries.

- Abstract
Background: Primary angioplasty has been shown to improve the outcome in selected patients with ST-segment elevation myocardial infarction. However, no data have been reported of patients with proximal left anterior descending artery occlusion. In the Zwolle-6 randomized trial, a total of 1683 consecutive patients with ST-segment elevation myocardial infarction were randomized to stenting or balloon angioplasty without any exclusion criteria. The aim of this substudy was to investigate the benefits of coronary stenting as compared to balloon angioplasty in patients with proximal left anterior descending artery occlusion., Methods: From April 1997 to October 2001, among a total of 1683 consecutive patients with ST-segment elevation myocardial infarction randomized to stenting or balloon angioplasty before the initial angiography, a total of 218 patients underwent primary angioplasty of proximal left anterior descending artery occlusion. One-year follow-up data were available from all patients., Results: A total of 107 patients were randomized to stent and 111 patients to balloon angioplasty. The cross-over rates from balloon to stent and stent to balloon were 35.1 and 13.1%, respectively (P<0.0001). The groups were comparable in terms of postprocedural thrombolysis in myocardial infarction flow, myocardial blush grade, distal embolization, and ST-segment resolution. Stenting was associated with benefits in terms of restenosis (27.6 vs. 53.8%, P=0.03) and target vessel revascularization (15.0 vs. 24.3%, P=0.081), whereas no difference was observed in mortality (11.2 vs. 13.5%, P>0.1) and reinfarction (11.2 vs. 8.1%, P>0.1) as compared with balloon angioplasty., Conclusion: As compared with balloon angioplasty, routine stenting does reduce angiographic restenosis, without significant benefits in terms of death and reinfarction among patients undergoing primary angioplasty for ST-segment elevation myocardial infarction due to proximal left anterior descending artery occlusion.

- Abstract
Background: Although the prognostic significance of creatine kinase (CK) and creatine kinase-MB (CK-MB) after myocardial infarction has been established after thrombolysis or no reperfusion therapy, there is limited evidence of the prognostic importance after primary percutaneous coronary intervention (PCI)., Methods: In this prospective, observational study, individual data from all patients who survived at least 2 days after primary PCI between 1991 and 2004 in our hospital were recorded. The association between enzymatic infarct size (examined by peak CK and peak CK-MB levels, each divided into tertiles) and both left ventricular ejection fraction (LVEF) and 1-year mortality was evaluated., Results: In the study group of 4670 patients, mean peak CK was 2327 U/L (SD 2008) and mean peak CK-MB was 244 U/L (SD 208). Both increased CK and CK-MB were associated with a lower LVEF. A total of 252 patients (5.4%) died between 2 days and 1 year after admission. Both peak CK and peak CK-MB were higher in those who died. Particularly, patients in the highest tertile of either peak CK or peak CK-MB had increased mortality, whereas the differences between the lower tertiles were not significant. In 2738 patients, after multivariable analysis including LVEF, the hazard ratio for 1-year mortality in patients in the highest CK tertile was 2.28 (95% CI 1.32-3.91) and for CK-MB, 1.91 (95% CI 1.11-3.26), compared to those in the other tertiles., Conclusions: According to this large-scale study, peak CK and peak CK-MB are comparable independent predictors of LV function and 1-year mortality in patients after primary PCI.

- Abstract
White blood cell (WBC) count and high-sensitive C-reactive protein (hs-CRP) are both used as markers of inflammation and prognosis after an ST elevation myocardial infarction (STEMI), but it is unknown whether they have independent prognostic value. We investigated the association and independent prognostic importance of WBC and hs-CRP after STEMI. In this subanalysis of the On-TIME trial, in 490 of 507 (97%) patients, either WBC count or CRP, and in 362 (71%) patients, both WBC count and CRP, were measured on admission before primary percutaneous coronary intervention. There was no significant correlation between WBC count and CRP (R = 0.080). Higher levels of CRP were associated with a reinfarction or death within 1 year (mean hs-CRP 14.2 +/- 20.4 vs 6.1 +/- 14.2, p = 0.006), but CRP was not associated with enzymatic infarct size (lactate dehydrogenase, LDHQ48) or left ventricular ejection fraction. A higher baseline WBC count was associated with larger LDHQ48 and lower left ventricular ejection fraction but not with 1-year reinfarction or death. In conclusion, although both WBC count and CRP are markers of inflammation and predictors of outcome after STEMI, we did not find a correlation between baseline WBC count and CRP levels in patients treated with primary percutaneous coronary intervention for STEMI. The mechanisms by which WBC counts predict outcome were related to myocardial infarct size whereas CRP were not.

- Abstract
Objective: To evaluate the prognostic role of postprocedural single-lead residual ST-segment deviation for electrocardiographic evaluation of myocardial perfusion in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary angioplasty., Design: Prospective observational clinical cohort study., Setting: Tertiary referral centre., Patients: 1660 patients treated with primary angioplasty for STEMI., Main Outcome Measure: Mortality at 1-year follow-up., Results: Single-lead ST-segment deviation significantly correlated with infarct size, predischarge ejection fraction, distal embolisation and myocardial blush grade 3. At 1-year follow-up, 63 patients had died. The method correlated well with 1-year mortality. At multivariate analysis, after correction for baseline demographic, clinical and angiographic variables, postprocedural single-lead ST-segment deviation showed better accuracy than residual single-lead ST-segment elevation or resolution and residual 12-lead ST-segment deviation., Conclusions: This study showed that maximal residual ST-segment deviation in a single lead at 3 hours after the procedure is an easy and accurate predictor of 1-year mortality after primary angioplasty for STEMI.

- Abstract
Background: Despite their proven beneficial effects and inclusion in the guidelines, glycoprotein (GP) IIb/IIIA blockers are underused in daily practice in patients with non ST-segment elevation acute coronary syndrome (NSTE ACS). This study combines the data from two randomized controlled trials, comparing routine upstream versus selective down stream use of tirofiban in patients with NSTE ACS., Methods: Inclusion criteria for both studies (ELISA-1 and 2) were angina pectoris, with ST depression >1 mm and or a positive cardiac biomarkers. All patients were scheduled for coronary angiography. The primary and secondary end points for both studies were enzymatic infarct size (LDHQ48) and initial TIMI flow of the culprit lesion respectively., Results: From August 2000 to January 2005, 273 patients were randomized to routine upstream tirofiban and 275 patients to selective down stream use of tirofiban. Selective down stream tirofiban was used in 55 patients (20%). Patients in the upstream group more often had a patent culprit lesion (65% vs. 50%, P=0.003) and a significantly smaller enzymatic infarct size, LDHQ48 median (25-75%): 125 (55-309) vs. 189 (68-504) IU/l, P=0.006 as compared to the selective down stream group. Subgroup analysis showed that routine upstream tirofiban was particularly effective in males, patients with a positive troponin on admission and in those not pretreated with clopidogrel., Conclusion: Routine upstream GP IIb/IIIa is mainly effective in patients with elevated troponin on admission and those not pretreated with clopidogrel. Large scale randomized trials are needed to evaluate the effect of GP IIb/IIIa blockers on top of clopidogrel pretreatment on major adverse cardiac events.

- Abstract
Background: The prognostic importance of elevated cardiac enzymes after elective percutaneous coronary intervention has been debated. Therefore, we performed a prospective observational study to evaluate the prognostic value of postprocedural rise of troponin T and creatine kinase., Methods: Troponin T (cut-off value 0.05 ng/ml) and creatine kinase (cut-off value 180 IU/l with muscle-brain fraction >4%) were measured 12 h after elective percutaneous coronary intervention in 713 consecutive patients without elevated troponin before the procedure. Primary endpoint was the combined incidence of death, myocardial infarction, stroke, repeat angiography or re-admission because of anginal symptoms during the follow-up period., Results: Troponin was elevated after the procedure in 150 patients (21%) and creatine kinase in 66 pts (9%), with a strong association between increased troponin and creatine kinase. After a mean follow-up of 10.9 months, mortality was low (1%) and not associated with increased troponin or creatine kinase. There was, however, a strong relation between postprocedural troponin and re-admission for angina (p=0.001) or myocardial infarction (p=0.001). Furthermore, troponin rise was significantly associated with an increased risk of the primary endpoint (relative risk 1.55 95% confidence interval 1.01-2.38). After multivariate analysis, troponin elevation but not increased creatine kinase was associated with an increased risk of the primary endpoint (relative risk 1.59 95% confidence interval 1.02-2.47 for troponin elevation versus 1.16 95% confidence interval 0.62-2.15 for increased creatine kinase)., Conclusion: Increase of troponin T after elective percutaneous coronary intervention has stronger prognostic implication when compared to increased creatine kinase.

- Abstract
Background: Coronary stenting has been shown to improve clinical outcome in comparison with balloon angioplasty in patients with ST-segment elevation myocardial infarction (STEMI). However, few data have been reported so far in the elderly. Thus, the aim of the current study was to evaluate the benefits from routine stenting in this high-risk subset of patients., Methods: In the Zwolle-6 randomized trial a total of 1683 consecutive patients with STEMI was randomized to stenting or balloon angioplasty without any exclusion criteria. One year follow-up data were available from all patients., Results: Among a total of 143 patients older than 75 years, 73 were randomized to stent and 67 to balloon angioplasty. No difference was observed in 1-year mortality (17.1% vs 11.9%, p=NS), reinfarction (9.2% vs 11.9%, p=NS), target vessel revascularization (15.8% vs 14.9%, p=NS) or major adverse cardiac events (28.9% vs 26.9%, p=NS) between the groups at 1-year follow-up., Conclusion: In conclusion, our study showed that as compared to balloon angioplasty, the clinical benefits of routine coronary stenting in the setting of acute myocardial infarction may not be necessarily applicable to elderly patients.

- Abstract
BACKGROUND.: Although techniques for percutaneous coronary intervention (PCI) have improved, patients with PCI of more vessels may still have an increased risk. We performed a prospective observational study evaluating the differences between multivessel and single-vessel procedures according to postprocedural troponin T (TnT) elevation and events during follow-up. METHODS.: The study included 713 patients without elevated TnT (<0.05 ng/ml) before PCI. Primary endpoint was the combined endpoint of death, myocardial infarction, stroke, repeat coronary angiography and readmission for anginal symptoms during the mean follow-up of 10.9 months. RESULTS.: TnT after PCI was elevated in 150 patients (21%) and was significantly associated with an increased incidence of the primary endpoint (RR 1.55, 95% CI 1.01 to 2.38). PCI of more than one vessel was performed in 146 patients (20%). These patients more often had increased TnT levels after the procedure (31.5 vs. 18.3%, p=0.001) and an increased incidence of the primary endpoint during follow-up (28 vs. 19%, p=0.01). After multivariable analysis, multivessel PCI was a statistically significant predictor of postprocedural TnT increase (OR 1.90, 95% CI 1.17 to 3.06). Multivessel PCI was also associated with an increased risk of the primary endpoint (OR 1.73, 95% CI 1.18 to 2.52), but after adjusting for multivessel disease this association was not statistically significant (OR 1.42, 95% CI 0.92 to 2.19). CONCLUSION.: Elective PCI of more vessels in one session is, in comparison with single-vessel PCI, more often associated with postprocedural troponin T rise and a (nonsignificantly) higher incidence of cardiac events during follow-up. Whether staged PCI is associated with less morbidity has to be assessed. (Neth Heart J 2007;15:178-83.).

- Abstract
Background: Optimal epicardial recanalization does not guarantee optimal myocardial perfusion. The aim of the current study was to evaluate angiographic and electrocardiographic markers of reperfusion in the prediction of infarct size in patients with STEMI undergoing successful primary angioplasty., Methods: Our population is represented by 270 STEMI patients with ST successful primary angioplasty (postprocedural TIMI 3 flow and residual stenosis <50%) with available corrected TIMI frame count (cTFC), myocardial blush grade (MBG), ST-segment resolution and enzymatic infarct size (peak CK-MB) analyses., Results: A significant linear relationship with enzymatic infarct size was observed for all markers of reperfusion, except for ST-segment resolution. These data were confirmed even when analyzed as continuous variables in case of cTFC (r=0.13, p=0.035), postprocedural residual cumulative ST-segment elevation (r=0.41, p<0.0001) and deviation (r=0.45, p<0.0001). At multivariate analysis applied to postprocedural angiographic and electrocardiographic markers of reperfusion, cumulative residual ST-segment deviation, myocardial blush grade, and corrected TIMI frame count were independent predictors of enzymatic infarct size., Conclusions: This study showed that, among patients with STEMI treated by primary angioplasty, cTFC, MBG and cumulative residual ST-segment deviation are independent predictors of infarct size. Therefore, angiography and electrocardiography may provide complementary information in the evaluation of myocardial perfusion.

- Abstract
Background: Guidelines are mainly based upon results of randomised controlled clinical trials. However, due to low external validity of these trials, their results can not reasonably be applied to all patients in routine practice. In our hospital, all patients with ST-elevation myocardial infarction (STEMI) are eligible for inclusion in one of our ongoing trials or registries. To asses differences between patients enrolled versus not-enrolled in a trial or registry, we evaluated all patients with a discharge diagnose of STEMI during the study period., Methods: Retrospectively, individual patient data from all patients with a discharge diagnosis of STEMI between Jan 2001 and Dec 2001 were evaluated. Follow-up data were obtained until Dec 2004., Results: A total of 583 patients were discharged with a diagnosis of STEMI. About 455 (78%) patients were enrolled in one of the ongoing clinical trials or registry and 128 were not. Not-enrolled patients were significantly older; more often had a history of previous MI and had higher risk profiles. Multivariate analysis revealed that higher age was the only independent predictor for non enrollment. Not-enrolled patients were more often treated conservatively and had a higher mortality rate (36% vs. 6%, P << 0.001). After multivariate analysis, non-enrollment (OR: 95% CI) 4.02 (1.98-8.16), age 1.07 (1.04-1.12), and diabetes 2.39 (1.17-4.89) were the only independent predictors of long term mortality., Conclusions: This study shows important differences in baseline characteristics, treatment, and prognosis between patients with STEMI who were enrolled or not in a trial. To better reflect daily clinical practice, guidelines should also consider results of observational studies of unselected patients.
