Introduction: The beneficial outcome of the radial (RA) over femoral approach (FA) in ST-segment elevation myocardial infarction (STEMI) has been widely demonstrated. However, most of the studies excluded patients with STEMI and cardiogenic shock (CS)., Objectives: We sought to evaluate periprocedural outcomes of percutaneous coronary intervention (PCI) with RA and FA in patients with STEMI complicated by CS using data from the Polish National PCI Registry (ORPKI)., Patients and Methods: A total of 3,565 consecutive patients with STEMI and CS treated with emergent PCI and stent implantation were included. Data was collected prospectively between 2014 and 2018 from 151 tertiary primary-PCI centers in Poland. To avoid possible selection bias, a propensity score matching (PSM) was used to create 945 matched pairs treated via RA or FA., Results: No differences were reported in baseline characteristics, clinical presentation and delays in treatment between RA and FA after the PSM. Similar radiation doses and the total amount of contrast were used in both groups. A similar rate of periprocedural complications was observed in both RA and FA. However, RA was associated with reduced periprocedural mortality (9.4% (89) vs. 18.6% (176); P=0.001) and lower incidence of cardiac arrest (9.7% (92) vs. 16.1% (152); P=0.001). In multivariable analysis, FA was the strongest independent predictor for increased periprocedural mortality (OR 2.087, 95% CI 1.629-2.674; P=0.001)., Conclusions: The radial approach was associated with lower periprocedural mortality compared with FA in patients with STEMI complicated by CS. RA seems to be a valuable option in technically feasible situations.

Coronary artery perforation (CAP) is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI). With a growing number of PCIs in complex lesions, the problem of CAP becomes even more important nowadays. Data on CAP rates in Poland are lacking. Presented study is an analysis of 344,517 consecutive patients treated with PCI between 2014 and 2017. Data were gathered from the Polish National PCI Registry (ORPKI). During 4 years of data collection CAP was observed in 595 (0.17%) cases. Patients diagnosed with CAP were older (69 years Q1:63; Q3:78 vs 66 years Q1:60; Q3:75; p <0.001), more often female (44% vs 32%; p <0.001), with arterial hypertension (77% vs 71%; p = 0.002), and chronic kidney disease (8.9% vs 5.4%; p <0.001). In the CAP group, a higher rate of PCIs within chronic total occlusions (8.7% vs 2.3%; p <0.001) and saphenous vein graft lesions (2.7% vs 1.3%; p = 0.002), as well as rotational atherectomy procedures (2.2% vs 0.4%; p <0.001) was observed. Patients with CAP had higher rate of no-reflow phenomenon (5.5% vs 0.5%; p <0.001) and greater periprocedural mortality (4.2% vs 0.5%; p <0.001). In conclusion, our study confirms that CAP is more common during complex PCI procedures in high-risk patients. CAP occurrence is associated with worse immediate outcomes including increased periprocedural mortality., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) is an important clinical problem especially in the era of extensive utilization of coronary angiography in MI patients. Its pathophysiology is poorly understood which makes diagnostics and treatment of MINOCA challenging in everyday clinical practice. The aim of the study was to assess characteristics of MINOCA patients in Poland based on data from the Polish National ORPKI Registry. In 2016, 49,893 patients with non-ST-segment elevation (NSTEMI) or ST-segment elevation (STEMI) myocardial infarction entered the ORPKI registry. MINOCA was defined as a non-obstructive coronary artery disease (CAD) and a lack of previous coronary revascularization. MINOCA was identified in 3924 (7.8%) patients and clinical presentation was more often NSTEMI than STEMI (MINOCA: 78 vs. 22%; obstructive CAD 51.1 vs. 48.9%; p < 0.0001). MINOCA patients were younger and more often females with significantly lower rates of diabetes, smoking, arterial hypertension, kidney disease, previous MI and previous stroke comparing to patients with obstructive CAD. Myocardial bridge was visualized in angiography more often in the MINOCA group (2.2 vs. 0.4%; p < 0.0001). Additional coronary assessment inducing fractional flow reserve, intravascular ultrasound, optical coherence tomography was marginally (< 1%) used in both groups. Periprocedural mortality was lower in MINOCA group (0.13% vs. 0.95%; p < 0.0001). MINOCA patients represent a significant proportion of MI patients in Poland. Due to multiple potential causes, MINOCA should be considered rather as a working diagnosis after coronary angiography and further efforts should be taken to define the cause of MI in each individual patient.

Background: During the first decade following the coronary bypass grafting, at least ten percent of the patients require percutaneous coronary interventions (PCI) due to graft failure. Saphenous vein grafts (SVG) are innately at a higher risk of periprocedural complications. The present study aimed to investigate predictors of periprocedural complications of PCI within coronary artery bypass grafts., Methods: This study analyzed data gathered in the Polish National Registry (ORPKI) between January 2015 and December 2016. Of the 221,195 patients undergoing PCI, data on 2,616 patients after PCI of SVG and 442 patients after internal mammary artery (IMA) were extracted. The dissimilarities in periprocedural complications between the SVG, IMA and non-IMA/SVG groups and their predictors were investigated., Results: Patients in the SVG group were older (p < 0.001), with a higher burden of concomitant disease and differing clinical presentation. The rate of de-novo lesions was lower, while restenosis was higher at baseline in the SVG (p < 0.001). The rate of no-reflows (p < 0.001), perforations (p = 0.01) and all periprocedural complications (p < 0.01) was higher in the SVG group, while deaths were lower (p < 0.001). Among the predictors of no-reflows, it was found that acute coronary syndromes (ACS), thrombectomy and past cerebral stroke, while the complications included arterial hypertension, Thrombolysis in Myocardial Infarction (TIMI) flow before PCI and thrombectomy., Conclusions: Percutaneous coronary interventions of SVG is associated with increased risk of specific periprocedural complications. The ACS, slower TIMI flow before PCI and thrombectomy significantly increase the periprocedural complication rate in patients undergoing PCI of SVG.

Background: Despite an increase in the proportion of nonagenarians in demographic structure, there is still a paucity of data on the utilization and outcome of percutaneous coronary interventions (PCIs) in this population. Also, very old patients are under-represented in randomized clinical trials and their treatment is still an emerging challenge. Thus, we sought to compare patient profiles and periprocedural outcomes of PCI in nonagenarians and patients younger than 90 years., Patients and Methods: Data were based on the Polish National Registry of PCI (ORPKI). A total of 651 080 consecutive patients with stable angina (SA) (n=260 920) or acute coronary syndrome (ACS) (n=390 160) undergoing PCI with at least one stent implanted were included. Patients were stratified according to age (<90 and ≥90 years)., Results: Of all included patients, 4413 (0.7%) were older than or equal to 90 years. A similar rate of periprocedural complications was observed in both groups. However, cardiac arrest during both angiography and PCI occurred more often in nonagenarians (0.21 vs. 0.83%; 0.42 vs. 1.07%, respectively, for both P=0.001). Similarly, periprocedural mortality was higher in patients older than or equal to 90 years (0.27 vs. 1.88%; P=0.001). There were no differences in periprocedural outcomes between groups in the SA setting. However, a higher rate of periprocedural cardiac arrest [1971 (0.51%) vs. 43 (1.15%); P=0.001] and mortality [1622 (0.42%) vs. 83 (2.2%); P=0.001] were observed in nonagenarians compared with younger counterparts admitted with ACS., Conclusion: Nonagenarians undergoing PCI because of SA may have similar outcomes as patients younger than 90 years. In ACS presentation, they may have worse outcomes than younger counterparts.

Background: The relationship between chronic obstructive pulmonary disease (COPD) and periprocedural complications of percutaneous coronary interventions (PCIs) is influenced by several factors. We aimed to investigate the association between COPD, its complication type and rate in patients undergoing PCI., Methods: Data were prospectively collected using the Polish Cardiovascular Intervention Society national registry (ORPKI) on all PCIs performed in Poland between January 2015 and December 2016. COPD was present in 5,594 of the 221,187 patients undergoing PCI. We assessed the frequency and predictors of periprocedural complications in PCI., Results: Patients with COPD were elder individuals (70.3 ± 9.9 vs. 67 ± 10.8 years; p < 0.05). We noted 145 (2.6%) periprocedural complications in the COPD group and 4,121 (1.9%) in the non-COPD group (p < 0.001). The higher incidence of periprocedural complications in the COPD patients was mainly attributed to cardiac arrest (p = 0.001), myocardial infarctions (p = 0.002) and no-reflows (p < 0.001). COPD was not an independent predictor of all periprocedural complications. On the other hand, COPD was found to be an independent predictor of increased no-reflow risk (odds ratio [OR] 1.447, 95% CI 1.085-1.929; p = 0.01), and at the same time, of decreased risk of periprocedural allergic reactions (OR 0.117, 95% CI 0.016-0.837; p = 0.03)., Conclusions: In conclusion, periprocedural complications of PCIs are more frequent in patients with COPD. COPD is an independent positive predictor of no-reflow and a negative predictor of periprocedural allergic reactions., Competing Interests: The authors have declared that no competing interests exist.

Conflicting data exist regarding the associations between on-site surgical backup and outcomes after primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI). Thus, we sought to assess the impact of such a backup on periprocedural outcomes of primary PCI using data from the Polish National Registry of PCI. From 2014 to 2016 data on 66,707 patients presenting with STEMI undergoing primary PCI from 154 centers were collected. Patients were divided into 2 groups based on the presence of on-site surgical backup. Of 66,707 patients, 15,040 (22.6%) patients were treated in 28 centers with on-site surgical backup. On-site surgical backup was associated with a higher center PCI annual volume (662.4 ± 301.8 vs 1098.7 ± 483.5; p <0.001), but a lower operator PCI annual volume (226.7 ± 126.0 vs 207.8 ± 96.6; p <0.001). The periprocedural mortality (1.60% vs 1.09%; p <0.001) was lower in patients from centers with on-site cardiac surgery and both on-site surgical backup (odds ratio [95% confidence interval], 0.618 [0.517; 0.738]; p <0.001) and the mean number of PCIs by operator per year (odds ratio per 10 [95% confidence interval], 0.990 [0.984; 0.996]; p = 0.001] were independent predictors of periprocedural death. In conclusion, results of our study suggest that periprocedural mortality in patients undergoing primary PCI for STEMI is lower in centers than without on-site cardiac surgical backup. Whether this effect on mortality is attributable to such backup itself and/or whether surgical backup is a marker of overall better medical care and adherence to professional guidelines, this needs clarification in further studies., (Copyright © 2018.

INTRODUCTION    The incidence of chronic obstructive pulmonary disease (COPD) in patients treated with percutaneous coronary intervention (PCI) is underestimated, and the effect of COPD on atherosclerosis and the outcomes of PCI is not fully understood. OBJECTIVES    The aim of this study was to assess the impact of COPD on periprocedural outcomes of PCI, as well as its relationship with clinical presentation and the type of coronary artery lesions. PATIENTS AND METHODS    Data were prospectively collected using a national electronic registry of PCI procedures performed in Poland between January 2015 and December 2016. Out of the 221 187 PCIs, 5594 patients had been diagnosed with COPD before the intervention. RESULTS    Patients with COPD were older than those without COPD (mean [SD] age, 70.3 [9.9] years vs 67 [10.8] years; P <0.001) and more often were males (72.3% vs 67.8%; P <0.001). Non-ST‑segment elevation myocardial infarction (NSTEMI) was a more common clinical presentation of coronary artery disease (CAD) in the COPD group, while ST‑segment elevation myocardial infarction (STEMI) occurred more frequently in the non‑COPD group. Multivessel disease (MVD) with or without left main coronary artery (LMCA) involvement and separate LMCA was diagnosed more often in the COPD group. At baseline, the culprit lesion was more often restenosis and in‑stent thrombosis in the COPD group, whereas de‑novo lesion-in the non‑COPD group. The rates of periprocedural mortality and myocardial infarction did not differ between the groups with and without COPD (0.13% vs 0.12%, P = 0.88 and 0.53% vs 0.45%, P = 0.39, respectively). COPD was found to be an independent predictor of restenosis assessed before PCI in patients with a history of PCI (P = 0.006). CONCLUSIONS    Patients with COPD diagnosed before PCI are at an increased risk of MVD with or without LMCA involvement and NSTEMI. Restenosis and in‑stent thrombosis occur more often in patients with COPD before PCI.

Background: Current STEMI guidelines recommend thrombectomy should be considered during primary PCI. Multiple data from randomized clinical trials, registries, and metanalysis have confirmed the efficacy of thrombectomy in terms of surrogate endpoints like better myocardial perfusion, less pronounced distal embolization, and conflicting results on lower all-cause mortality. Our aim was to analyze long-term outcome of STEMI patients treated with manual thrombectomy during primary PCI in a contemporary national registry., Methods: There were 13 catheterization laboratories in Poland that enrolled patients in NRDES Registry. Patients were divided into two groups: those that were treated with manual thrombectomy for their primary PCI vs. those who were not., Results: There were altogether 2,686 patients enrolled in the NRDES Registry of whom 1,763 were diagnosed with STEMI (66%). Aspiration thrombectomy was used in 673 of these cases (38%) and 1,090 (62%) patients were treated without thrombectomy during the index primary PCI. Overall mortality at 1 year was 11.03% in thrombectomy and 7.46% in no thrombectomy group respectively (P = 0.0292 which became insignificant after propensity score matching adjustment P = 0.613). Specific subgroup analyses revealed that there was no benefit from aspiration thrombectomy in neither subgroup., Conclusions: Manual aspiration thrombectomy in patients undergoing primary PCI for STEMI was not associated with improved long-term 1-year clinical outcome. Subgroup analysis did not reveal any specific setting in which thrombectomy would be clinically superior. © 2014 Wiley Periodicals, Inc., (© 2014 Wiley Periodicals, Inc.)

Objectives: To analyze long-term outcome of ST-Elevation Myocardial Infarction (STEMI) and non-STEMI (NSTEMI) patients treated with Drug Eluting Stents (DES) stents with regard to mortality and stent thrombosis rates based on the national Polish PCI registry database., Background: Only a few studies suggested potential trend towards lower mortality in STEMI patients treated with DES. Current European Society of Cardiology STEMI guidelines recommend DES use only with one restriction to suspected patient poor compliance or contraindication to dual antiplatelet therapy., Methods: Thirteen high-volume interventional cardiology centers in Poland enrolled patients in National Registry of Drug Eluting Stents (NRDES) Registry from October 2010 till October 2011., Results: There were 2686 patients enrolled in NRDES Registry. Eighty five patients (3%) had both DES and BMS implanted at index PCI procedure and were excluded from further analysis. A subpopulation of STEMI (1709; 66%) and NSTEMI (892; 34%) patients was selected for BMS vs DES comparison. A significant difference in favor of DES group for 1-year mortality was found in STEMI subgroup (P < 0.0001-unadjusted and P = 0.0497 after propensity score adjustment). No such differences were noticed for NSTEMI subgroup or stent thrombosis comparisons., Conclusions: A strong selection bias for DES stents was observed with regard to demographic and angiographic characteristics in both STEMI and NSTEMI. DES implantation was associated with similar ischemic outcome to BMS at 1-year follow-up. STEMI patients with DES presented a trend towards lower long-term mortality at 1 year in comparison to BMS., (Copyright © 2013 Wiley Periodicals, Inc.)

The current article summarises more than 12 years' experience in the treatment of ST-segment elevation myocardial infarction in the Małopolska region (southern part of Poland). Data on the development phase of the STEMI treatment network, as well as the current status of interventional treatment of acute coronary syndromes in that region of Poland are provided.

Background: Previous studies with thrombectomy showed different results, mainly due to use of thrombectomy as an additional device not instead of balloon predilatation. The aim of the present study was to assess impact of aspiration thrombectomy followed by direct stenting., Methods: Patients with ST elevation myocardial infarction (STEMI) <6 hours from pain onset and occluded infarct-related artery in baseline angiography were randomized into aspiration thrombectomy followed by direct stenting (TS, n = 100) or standard balloon predilatation followed by stent implantation (n = 96). The primary end point of the study was the electrocardiographic ST-segment elevation resolution >70% (STR > 70%) 60 minutes after primary angioplasty (percutaneous coronary intervention [PCI]). Secondary end points included angiographic myocardial blush grade (MBG) after PCI, combination of STR > 70% immediately after PCI and MBG grade 3 (optimal myocardial reperfusion), Thrombolysis In Myocardial Infarction flow after PCI, angiographic complications, and in-hospital major adverse cardiac events., Results: Aspiration thrombectomy success rate was 91% (crossing of the lesion with thrombus reduction and flow restoration). There was no significant difference in STR ≥ 70% after 60 minutes (53.7% vs 35.1%, P = .29). STR > 70% immediately after PCI (41% vs 26%, P < .05), MBG grade 3 (76% vs 58%, P < .03), and optimal myocardial reperfusion (35.1% vs 11.8%, P < .001) were more frequent in TS. There was no difference in between the groups in 6-month mortality (4% vs 3.1%, P = .74) and reinfarction rate (1% vs 3.1%, P = .29)., Conclusions: Aspiration thrombectomy and direct stenting is safe and effective in STEMI patients with early presentation (<6 hours). The angiographic parameters of microcirculation reperfusion and ECG ST-segment resolution directly after PCI were significantly better in thrombectomy group despite the lack of the difference in ST-segment resolution 60 minutes after PCI., (Copyright © 2010 Mosby, Inc.

Background: Hyperglycemia on admission is a predictor of unfavorable prognosis in patients with acute myocardial infarction (AMI). Data concerning associations between elevated glucose level on admission and other in-hospital complications are still limited., Methods: A total of 607 AMI patients with complete admission glucose data in the Krakow Registry of Acute Coronary Syndromes were identified and were stratified according to glucose admission level., Results: A total of 71.5% of patients were with admission glucose level <7.8 mmol/l, 17.6% of patients with 7.8-11.0 mmol/l, and 10.9% of patients with ≥11.1 mmol/l. In-hospital mortality for patients treated conservatively was higher in patients with higher admission glucose (8.0 vs. 25.0 vs. 39.1%, respectively, P < 0.0001), and significant mortality difference was confirmed both for diabetic and non-diabetic patients. Admission hyperglycemia was associated with increased risk of ventricular tachycardia/ventricular fibrillation, atrial fibrillation, second to third atriventricular block, pulmonary oeadema, but not ischemic stroke and blood transfusion during index hospital stay., Conclusions: Elevated admission glucose levels are associated with increased risk of life-threatening complications, especially arrhythmias in diabetic and non-diabetic AMI patients. This increased risk of complications is one of the possible explanations for the elevated in-hospital mortality in AMI patients presenting with hyperglycemia.

Background: The majority of ST-segment elevation myocardial infarction (STEMI) patients are admitted to centers without primary percutaneous coronary intervention (PCI) facilities. Purpose of the study was to determine safety and outcomes in STEMI patients with transfer delay to PCI>90 min receiving half-dose alteplase and abciximab before PCI (facilitated PCI with reduced-dose fibrinolysis)., Methods and Results: Outcomes of 669 STEMI patients (<12 h chest pain, non shock, fibrinolysis eligible, <75 years) with transfer delay to PCI>90 min who received half-dose alteplase and full-dose abciximab and were immediately transferred for PCI were compared with primary PCI effects in 1311 patients with transfer delay <90 min. Mean time from symptom-onset to PCI was longer (357 ± 145 min vs. 201 ± 177; P<0.001) in facilitated PCI with reduced-dose fibrinolysis group. In-hospital and 12-month outcomes were similar in both groups, however bleeding events were more frequent in facilitated PCI group (hemorrhagic stroke 0.9% vs. 0%; P<0.001; severe+moderate 5.5% vs. 2.3%; P<0.001)., Conclusions: This is the first large report showing the safety and benefits of transportation with very long transfer delay (>90 min) for facilitated PCI with reduced-dose fibrinolysis in STEMI patients. In fact, pharmacological treatment (combotherapy) was effective in overcoming the deleterious effects of long time-delay on outcome, with similar survival as compared to short-time transportation, despite higher risk of major bleeding complication., (Copyright © 2008.

Background: The purpose was to identify predictors of cardiogenic shock (CS) on admission and to asses associations between CS and real-life management patterns and outcomes in unselected cohort of acute coronary syndrome (ACS) patients admitted to hospitals without onsite invasive facilities., Methods: Data concerning in-hospital management and mortality of 56 (4.3%) patients with and 1257 (95.7%) without CS on hospital admission was assessed., Results: Prior myocardial infarction, prior heart failure symptoms, age, and diabetes mellitus were independently associated with increased risk of CS on admission. A total of 23.8% patients were transferred for invasive treatment during index hospital stay and the frequency of transfer was similar among patients with and without CS on admission (21.4% versus 23.9%; P = 0.75), but in the STEMI subgroup, patients with shock were transported less frequently (21.4% versus 43.8%; P = 0.0027). CS patients were less likely to receive guideline-recommended therapies including antiplatelet drugs, statins, and beta-blockers. In-hospital mortality was lower in non-shock patients (6.2% versus 63.6%; P < 0.001) and CS on admission was an independent predictor of in-hospital death., Conclusions: CS on admission is an important determinant of treatment strategy selection and is associated with unfavorable prognosis of ACS patients admitted to hospitals without on-site invasive facilities.

Elevated glucose level on admission is common in patients with acute coronary syndrome (ACS) and has been shown to be a strong predictor of adverse outcome in patients both with and without diabetes. The purpose of the study was to assess the impact of admission glucose on in-hospital mortality in patients with non-ST-segment elevation ACS treated in hospitals without on-site invasive facilities. We identified 807 patients with non-ST-segment elevation ACS treated conservatively in the 29 hospitals participating in the Krakow Registry of Acute Coronary Syndromes; 763 patients with complete admission glucose data were stratified according to admission glucose level. Of these, 24.2% had admission glucose level <5, 50.6% had a level 5 to 6.9, 10.9% had a level 7 to 8.9, 6.7% had a level 9 to 10.9, and 7.6% had a level > or =11 mmol/L. In-hospital mortality was higher in patients with higher admission glucose (admission glucose <5, 5 to 6.9, 7 to 8.9, 9 to 10.9, and > or =11 mmol/L: 0.5%, 2.6%, 7.2%, 9.8%, and 24.1% respectively, p <0.0001). Similarly, significant mortality difference was observed in patient subgroups stratified by admission glucose level and presence of diabetes mellitus and cardiogenic shock. Independent predictors of in-hospital death were age, cardiogenic shock, admission glucose, chronic obstructive pulmonary disease, and renal insufficiency. In conclusion, admission glucose level is a strong predictor of in-hospital death in patients with non-ST-segment elevation ACS remaining in hospitals without on-site invasive facilities. Impact of admission glucose on mortality is independent of diabetes and cardiogenic shock presence.

Background: According to the presenting electrocardiogram, acute myocardial infarction (MI) can by categorised generally as non-ST-segment elevation MI (NSTEMI) and ST-segment elevation MI (STEMI)., Aim: To assess the impact of the different acute MI categories on in-hospital management and mortality in hospitals without on-site invasive facilities., Methods: We identified 380 NSTEMI and 334 STEMI patients treated in the Malopolska Registry of Acute Coronary Syndromes from February to March 2005 and from December 2005 to January 2006. Data concerning in-hospital management and mortality were assessed., Results: Patients with NSTEMI were older and were more likely to have prior angina, prior MI and prior heart failure symptoms than STEMI patients. The NSTEMI patients were less likely to be transferred for invasive treatment (23.9 vs. 41.9%, p <0.0001) and receive glycoprotein IIb/IIIa inhibitors during index hospital stay. The use of low-molecular-weight heparin, beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin II antagonists, nitrates and statins was more frequent in NSTEMI patients. Among patients treated non-invasively, in-hospital mortality was high, but was lower in NSTEMI than STEMI patients (12.1 vs. 22.7%, p <0.0001). Independent predictors of in-hospital death in this group were age, cardiogenic shock, chronic obstructive pulmonary disease, and STEMI., Conclusions: Despite current recommendations, NSTEMI patients are still less likely to be transferred for invasive treatment than STEMI patients. Among patients treated non-invasively during index hospital stay, NSTEMI is associated with more favourable prognosis than STEMI, but the risk of in-hospital death is high. The hospital network should implement more frequently the strategy of early and urgent invasive treatment of NSTEMI patients.

Background: The purpose was to assess age-related differences in hospital management and mortality in non-ST-elevation acute coronary syndrome (NSTE ACS) patients treated conservatively, with a focus on the influence of aggressive pharmacological treatment on in-hospital clinical outcome., Methods: We identified 807 NSTE ACS patients treated conservatively in the 29 hospitals participating in the Krakow Registry of Acute Coronary Syndromes from February to March 2005 and from December 2005 to January 2006. Out of 807 patients' 32.1% were less than 65 years of age, 33% from 65 to 74, 30.5% from 75 to 84, and 5.3% >or= 85. For all patients, pharmacotherapy index based on the use of pharmacological treatment regimen during hospital stay was assessed. Each patient received 1 point for each of the following guideline-recommended drugs used: aspirin, clopidogrel, glycoprotein IIb/IIIa inhibitor, LMWH, beta-blocker, ACE inhibitor/angiotensin II receptor blocker and statin - the range of points being from 0 to 7., Results: Significant age-related differences in baseline characteristics and pharmacotherapy index values were found. In-hospital mortality was higher in elderly patients (2.4% vs. 3.4% vs. 8.9% vs. 14.0%, respectively for age groups, p < 0.0001). Similarly, in non-shock patients and in patients with elevated cardiac markers, age-dependent differences in mortality were observed. Independent predictors of in-hospital death were: age, cardiogenic shock, elevated cardiac markers and pharmacotherapy index., Conclusions: Advanced age is associated with less aggressive pharmacological treatment and higher in-hospital mortality in NSTE ACS patients remaining in community hospitals for conservative treatment. Broader implementation of current guidelines and more frequent invasive treatment might improve the outcomes of NSTE ACS patients regardless of age.

Introduction: Early reperfusion therapy significantly reduces mortality and improves outcome in ST-elevation myocardial infarction (STEMI). Primary percutaneous intervention has been proven to be a better therapeutic option than fibrinolysis when it can be performed by an experienced team of interventional cardiologists, within 90 minutes from the first medical contact. Despite the publication of guidelines of the European and American Scientific Societies (ESC and ACC/AHA), treatment of patients with STEMI is far from the optimum. The registry is an effective and reliable method to estimate the quality of treatment and demographic and epidemiologic characteristics of the population of a given region., Aim: To evaluate the therapeutic strategies of treatment of STEMI in district hospitals without a catheterisation laboratory in Małopolska., Methods: 29 district hospitals from Cracow and Małopolska province participated in the Registry of Acute Coronary Syndromes in Małopolska. Finally, 2382 patients with an initial diagnosis of acute coronary syndrome were included. In 867 of them, STEMI was finally diagnosed., Results: In district hospitals, most patients with STEMI (63%) did not receive any reperfusion therapy (25% of them were >75 years old, in 20% chest pain lasted longer than 12 hours, in 7% cardiogenic shock was diagnosed and 12% had contraindications for thrombolysis or were at increased risk of haemorrhagic complications). Fifteen percent of all 867 patients were transferred to the interventional cardiology centre (63% for primary PCI, 20% for facilitated PCI and the remaining 17% for rescue PCI). Fibrinolysis was applied in 21% of all patients with STEMI. In-hospital mortality rate was 14.3% in patients treated with fibrinolysis as compared to 15.9% in those treated conservatively. Multivariate logistic regression revealed that younger age (OR 0.93; 95% CI 0.91-0.95; p <0.0001), lack of diabetes (OR 0.54; 95% CI 0.30-0.98; p=0.04) and higher systolic blood pressure (OR 0.93; 95% CI 1.00-1.02; p=0.006) were independent factors predicting the referral of patients with STEMI for PCI. GP IIb/IIIa inhibitors were used in 5% of all patients and in 30% of those referred for PCI., Conclusions: Only one in every 7 patients with STEMI is qualified for PCI. Patients transferred to the centre with PCI facilities are younger, have no diabetes or hypotension. The use of GP IIb/IIIa inhibitors is limited. There is a need to establish local networks of hospitals with 24-hour catheterisation laboratory availability to increase frequency and efficacy of reperfusion therapy, especially in regions far from centres of interventional cardiology.
