Atypical aortic coarctation is a rare condition associated with Takayasu arteritis, and is characterized by symptoms caused either by hypotension in the lower half of the body or secondary hypertension in the upper half of the body, and heart failure. We report a rare case of axillofemoral bypass to improve congestive heart failure for atypical aortic coarctation complicating Takayasu arteritis. Augmented vascular bed and retrograde renal blood flow after axillofemoral bypass surgery could achieve effective blood pressure control and improve renal function and cardiac function (LVEF: 30% → 55%, BNP: 2943 pg/mL → 128 pg/mL). There were two contributing factors for improvement of heart failure such as the increased vascular bed and the increase in retrograde renal blood flow. We believe that axillofemoral bypass is effective for Takayasu arteritis patients with refractory heart failure. In daily practice, careful attention should be paid to an impact of cardiorenal‐aorta interaction in atypical aortic coarctation complicating Takayasu arteritis.

Aims We aimed to determine whether shortening the duration of P2Y12 inhibitor therapy can reduce the risk of bleeding without increasing the risk of major adverse cardiovascular events following coronary stenting in patients with atrial fibrillation (AF). Methods and results The SAFE-A is a randomised controlled trial that compared one-month and six-month P2Y12 inhibitor therapy, in combination with aspirin and apixaban for patients with AF who require coronary stenting. The primary endpoint was the incidence of any bleeding events, defined as Thrombolysis In Myocardial Infarction major/minor bleeding, bleeding with various Bleeding Academic Research Consortium grades, or bleeding requiring blood transfusion within 12 months after stenting. The study aimed to enrol 600 patients but enrolment was slow. Enrolment was terminated prematurely after enrolling 210 patients (72.7±8.2 years; 81% male). The incidence of the primary endpoint did not differ between the one-month and six-month groups (11.8% vs 16.0%; hazard ratio [HR] 0.70, 95% confidence interval [CI]: 0.33-1.47; p=0.35). Conclusions The study evaluated the safety of withdrawing the P2Y12 inhibitor from triple antithrombotic prescription one month after coronary stenting. However, enrolment was prematurely terminated because it was slow. Therefore, statistical power was not sufficient to assess the differences in the primary endpoint.

Background Nilotinib, a second-generation BCR-ABL tyrosine kinase inhibitor (TKI), is highly effective in the treatment of patients with chronic myeloid leukemia (CML), despite being more vasculotoxic than older TKIs such as imatinib. Herein, we present a case of nilotinib-associated vasospastic angina confirmed by an acetylcholine spasm provocation test. Case presentation A 62-year-old CML patient treated with 300 mg nilotinib twice daily complained of several episodes of rest angina and was hospitalized at our institution. Coronary angiography revealed no severe organic stenosis, and the acetylcholine spasm provocation test confirmed the diagnosis of vasospastic angina. Although treatment with a calcium channel blocker and nicorandil reduced the frequency of chest pain, angina symptoms continued to occur. At 10 months post discharge, the patient complained of increased frequency of angina; therefore, the nilotinib dosage was reduced to 150 mg twice daily. Consequently, the patient reported a significant improvement in chest symptoms. Conclusions This case report highlights the potential vasculotoxic effects of nilotinib. Cardiologists and hematologists should be vigilant for coronary artery spasm as a possible vascular adverse event caused by nilotinib.

Isolated right ventricular (RV) infarction is extremely rare and its diagnosis may be challenging, because RV infarction most often occurs simultaneously with infarction of the inferior wall of the left ventricle. A 66-year-old man with a history of diabetes mellitus presented with cold sweat and general malaise. Although his symptoms were atypical for myocardial infarction, he was quickly diagnosed with RV infarction and successfully underwent urgent percutaneous coronary intervention. He was definitely diagnosed with isolated RV infarction by a scintigram and cardiac magnetic resonance imaging. Our review showed the importance of the combined assessment in the diagnosis of isolated RV infarction.

An 81-year-old woman presented with massive melena. She required urgent hospitalization because of hyperprothrombinemia (international normalized ratio >9.9), induced by warfarin treatment following double valve replacement surgery she underwent 35 years prior, and had cirrhosis caused by chronic liver congestion. The next day, she became comatose (serum ammonia level, 417 μg/dL) and was diagnosed with hepatic encephalopathy with acute hyperammonemia. Despite the decrease in serum levels (53 μg/dL) following 3-day lactulose and rifaximin treatment, her consciousness level remained low (Glasgow Coma Scale, 6). Electroencephalogram on day 8 showed triphasic waves, but no obvious epileptic discharges. Brain magnetic resonance imaging (MRI) on day 1 was unremarkable (Fig. 1A–C) and showed bilateral and symmetrical cortical swelling in the insular, cingulate, frontal, and occipital cortices on day 10 (Fig. 1D–F), and showed reduction in the extent of the lesion at 3 weeks post-hospitalization (Fig. 1G–I). Her consciousness level recovered slightly later than the MRI findings. Ammonia detoxification in the brain occurs through glutamine formation through the glutamine synthesis pathway in astrocytes, leading to glutamine-induced astrocyte swelling and subsequent cerebral edema and even encephalopathy.1 Brain MRIs – which are essential in differential diagnoses – show symmetrical signal abnormalities in the insular and cingulate cortices.2-4 Close attention should be paid to secondary encephalopathy in patients with hyperammonemia.

Background Percutaneous coronary intervention (PCI) is often complicated by periprocedural myocardial injury (PMI) manifested by elevated cardiac biomarkers. The occurrence of PMI has been shown to be associated with worse clinical outcome over short- and long-term. Purpose We performed multidetector computed tomography (MDCT) and cardiac magnetic resonance imaging (CMR) to evaluate the relationship between culprit plaque characteristics and PMI. Methods A total of 90 patients who underwent elective PCI were underwent CMR and multidetector coronary tomography before PCI. The high intensity plaque (HIP) on CMR was defined as a coronary plaque to myocardium signal intensity ratio (PMR) of >1.4. The plaque characteristics and the presence of napkin-ring sign (NRS) were analyzed on MDCT. PMI was defined as an increase in cardiac Troponin T levels to more than 5 times the upper limit of normal at 24 h after PCI. Patients were divided into 2 groups according to the presence (Group I, n=26) or absence (Group II, n=64) of PMI. Results Spotty calcification, positive remodeling, low attenuation plaque and NRS on MDCT were significantly more observed in Group I than in Group II. HIP on CMR was significantly more observed in Group I than in Group II. In the multivariable logistic regression analysis, the presence of NRS and HIP were significantly independent predictors of PMI (odds ratio (OR) 4.82, 95% confidence interval 1.13–20.60, P=0.034 and OR 3.66, 95% CI 1.09–12.30, P=0.036, respectively). Moreover, for prediction of PMI, NRS and HIP showed a high positive predictive value of 81%, and their absence showed a high negative predictive value of 91%. Conclusions MDCT and CMR may play an important role in detecting which lesions are high risks for myocardial necrosis after PCI in elective coronary stenting.

Background Although elevated oxidized low-density lipoprotein could play critical roles in vulnerable plaque, there are no studies that compared coronary high-intensity plaque (HIP) on non-contrast T1-weighted magnetic resonance imaging (T1WI_MRI) and circulating malondialdehyde-modified low-density lipoprotein (MDA-LDL) levels for the prediction of cardiac events. Methods and results A total of 139 patients with coronary artery stenosis (>70%) were examined with non-contrast T1WI using a 1.5-T MRI (HIP: n=63, non-HIP: n=76). Scheduled percutaneous coronary intervention (PCI) for culprit lesions was performed within 48 h after MRI. HIP was defined as a signal intensity of coronary plaque to cardiac muscle ratio (PMR) of ≥1.4. At admission, circulating levels of MDA-LDL and other lipid-related markers were measured. We evaluated the subsequent cardiac events, which were defined as major adverse cardiac events (MACE; cardiac death, myocardial infarction, and/or ischemia-driven PCI) during follow-up periods (5.6±1.3 years). Circulating MDA-LDL levels were significantly higher in patients with HIP than in those without HIP (p Conclusions MDA-LDL levels might be associated with the presence of HIP in patients with coronary artery disease. Furthermore, adding PMR to MDA-LDL levels markedly improved MACE prediction. Funding Acknowledgement Type of funding source: None

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by a positive serum antiphospholipid antibody status. Patients with APS usually have an underlying hypercoagulable state, which can increase the risk of perioperative thromboembolism. We describe three patients with APS who underwent transcatheter aortic valve implantation for symptomatic severe aortic stenosis. Of them, two had complicated cerebrovascular events, and the other had no complications. Careful antithrombotic management is essential to minimize the risk of thromboembolism and bleeding in patients with APS.

INTRODUCTION There are few studies analyzing the association between the presence of coronary artery disease (CAD) and recurrence of atrial fibrillation (AF). This study evaluated the clinical impact of concomitant CAD and coronary revascularization on the recurrence of AF after catheter ablation. METHODS AND RESULTS From April 2008 to December 2015, 700 consecutive patients were treated with pulmonary vein isolation for AF as the initial procedure. Of those, 681 patients who simultaneously underwent coronary angiography were investigated. Patients with at least one coronary stenosis (≥70%) were classified as having obstructive CAD. Of 681 patients, 90 patients had CAD and 42 patients underwent percutaneous coronary intervention (PCI) for lesions with perfusion abnormalities on single-photon emission tomography. The recurrence of AF was significantly more frequent in patients with CAD (56%) than in those without CAD (39%) (P = .0011). On multivariable analysis, the predictors of AF recurrence were persistent or long-standing persistent AF [hazard ratio (HR): 1.36; 95% confidence interval (CI): 1.04-1.77; P = .023], left atrial diameter (HR: 1.04; 95% CI: 1.02-1.06; P

Background There have been no reviews regarding intravascular ultrasound (IVUS) catheter entrapment during percutaneous coronary intervention (PCI). This study investigated the incidence, retrieval methods, and outcomes of IVUS catheter stuck within implanted stents. Methods Between January 2015 and July 2018, a total of 794 consecutive patients underwent PCI for coronary artery disease. Among them, 705 patients underwent stent implantation using IVUS. The patients with IVUS catheter entrapment in an implanted stent were investigated. Results Ten patients (1.4%) suffered from an IVUS catheter stuck in an implanted stent. Among them, 7 patients had very tortuous lesions while 5 patients had severely calcified lesions. Seven patients (70%) underwent placement of the 3rd generation drug-eluting stent (DES), and the stent diameters were ≤2.5 mm among 8 patients (80%). Retrieval methods were the buddy wire technique, the double guide catheter technique, covering the exit port of IVUS catheter with a balloon catheter, and covering with GuideLiner® catheter (Vascular Solutions Inc., Minneapolis, MN, USA). On multivariable analysis, the predictors of IVUS catheter entrapment were tortuous lesion [odds ratio (OR), 8.21; 95% confidence interval (CI), 2.19–30.7; p = 0.002], 3rd generation DES (OR, 5.31; 95% CI, 1.08–26.1; p = 0.021), and stent diameter ≤2.5 mm (OR, 6.31; 95% CI, 1.29–30.8; p = 0.010). Furthermore, we identified 6 cases of IVUS catheter entrapment through a systematic literature review. Conclusions The IVUS catheter was almost stuck in tortuous lesions and the 3rd generation DES with a small diameter. We could successfully retrieve it in all cases using various retrieval techniques.

BackgroundIncreased levels of uric acid (UA) have been associated with cardiovascular disease. This association is generally stronger in women than men. However, gender differences in the prognostic value of UA in patients with acute coronary syndrome (ACS) are unknown. We investigated gender differences in the relationship between UA level and the prognosis in patients with ACS.MethodThis was an observational analysis of patients with ACS undergoing percutaneous coronary intervention enrolled in the Ibaraki Cardiac Assessment Study (ICAS) registry. We analyzed 1380 patients (330 women, 1050 men) with ACS who had information on UA. We assessed the association between UA and the incidence of major cardiovascular adverse events (MACE), defined as all-cause death, congestive heart failure, reinfarction, and stroke. Patients were divided according to gender-specific UA quartile.ResultsThe mean UA level in women was significantly lower than that in men (4.9mg/dl vs 5.9mg/dl, p

Objectives This study aimed to validate the clinical implications of audiovisual telesupport system use. Background An audiovisual telesupport system with supervisors has been effective in guiding procedures when surgeons have limited experience with the technique. However, cardiovascular catheter interventions using an audiovisual telesupport system has not been previously reported. Methods Starting in September 2017, two cardiologists in Kamisu Saiseikai Hospital (Kamisu, Japan, with limited cardiologists) began performing cardiovascular catheter interventions using an audiovisual telesupport system. This system enabled them to perform catheter interventions with the support of advisors in the University of Tsukuba (Tsukuba, Japan). We retrospectively assessed procedure time and complications of percutaneous coronary intervention (PCI) and catheter ablation (CA). Results In the first 10 months, 21 patients with coronary artery disease underwent PCI using this system. The mean procedure duration of PCI was 42 ± 10 min. Nine patients with tachyarrhythmia including supraventricular tachycardia (SVT), ventricular premature contraction (VPC), common atrial flutter, and paroxysmal atrial fibrillation (AF) underwent CA using this system. The mean CA procedure time was 134 ± 31 min for SVT, 100 ± 14 min for VPC, and 200 min for AF. All PCI and CA procedures were successfully performed without any complications. Conclusions The audiovisual telesupport system enabled cardiologists with limited human resources to provide safe and high-quality catheter interventions.

Background The prophylactic benefit of statins in reducing the incidence of contrast-induced acute kidney injury (CI-AKI) has been investigated in several studies with conflicting results. We sought to investigate whether statin pretreatment prevents CI-AKI in coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI). Methods A total of 2198 CAD patients who underwent PCI, except for those undergoing dialysis or who died within 7 days after angioplasty, were analyzed from the ICAS (Ibaraki Cardiovascular Assessment Study) multicenter registry. Analyzed subjects were divided into 2 groups according to statin pretreatment: statin pretreatment (n = 839) and non-statin pretreatment (n = 1359). Selection bias of statin pretreatment was adjusted by propensity score-matching method: pretreatment statin (n = 565) and non-statin pretreatment (n = 565). CI-AKI was defined as an increase in serum creatinine of ≥ 25% or 0.5 mg/dl from baseline within 1 week of contrast medium exposure. Results A total of 192 (8.7%) patients developed CI-AKI. No significant differences were observed in baseline patient characteristics between the statin and non-statin pretreatment groups after propensity score matching. In the propensity score-matched groups, the incidence of CI-AKI was significantly lower in patients with statin pretreatment than in those without statin pretreatment (3.5% vs.10.6%, odds ratio [OR]: 0.31, 95% confidence interval [CI]: 0.18–0.52, P < 0.001). Multivariate logistic regression analysis showed that statin pretreatment remained an independent negative predictor of CI-AKI (OR: 0.31, 95% CI: 0.18–0.53, P < 0.001) among propensity score-matched subjects. Conclusions Statin pretreatment was associated with a significant decrease in the risk of CI-AKI in CAD patients undergoing PCI in the ICAS Registry.

The purpose of this study was to find a safe dosing regimen for landiolol, an ultra-short-acting β-adrenergic blocking agent, to rapidly control supraventricular tachyarrhythmias (SVTs) in patients with heart failure (HF). Landiolol is reported to have good effects in the treatment of SVTs after cardiac surgery. We evaluated 52 patients with SVT and symptoms of HF (NYHA class III/IV, 10/42; EF 32 ± 12 %) on admission because of ischaemic disease (n = 10), non-ischaemic cardiomyopathy (n = 32), or valvular disease (n = 10). Paroxysmal/persistent atrial fibrillation and atrial tachycardia were present in 16 (30 %), 23 (45 %), and 13 (25 %) patients, respectively. The patients first underwent conventional therapy with carperitide, dobutamine, or milrinone. Intravenous landiolol was administered at an infusion rate of 1 μg/kg/min and, if no adverse effects developed, the maintenance dose, titrated to HR and blood pressure response, was increased. At an average dose of 10.8 ± 9.4 μg/kg/min, mean HR significantly decreased significantly from 133 ± 27 to 82 ± 15 beats/min (P < 0.01), whereas systolic blood pressure did not differ from baseline to attainment of an effective dose level (105 ± 21 vs. 101 ± 19 mmHg, P = ns). Within 60 min after initiation of therapy, all patients had achieved a 20 % reduction in HR at the maintenance dose. Transient asymptomatic hypotension requiring cessation of landiolol therapy occurred in three patients. Intravenous administration of landiolol was both effective in rapidly controlling HR for up to 24 h and useful as bridging treatment to additional therapy of oral β blockade, pulmonary vein catheter ablation, or cardiac resynchronisation therapy in patients with HF.

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and its etiology and pathogenesis have not been well understood. Intracoronary imaging modalities with intravascular ultrasound and optical coherence tomography would enable a precise diagnosis in this entity. Coronary angioscopy is also a unique tool for allowing direct visualization of the luminal surface of a vessel. We described an interesting case of SCAD documented with multimodality intracoronary imaging showing the presence of superficial lipid plaque nearby the coronary dissection entry point, which might have been associated with fragility of the arterial wall and the subsequent development of SCAD.

Plasma norepinephrine (NE) level can be a guide to mortality in patients with heart failure. This study aimed to evaluate the significance of plasma NE level compared with plasma natriuretic peptides (atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP)) levels in patients with atrial fibrillation (AF).Included in this study were 137 consecutive patients referred for catheter ablation of lone AF (paroxysmal in 90 and persistent in 47 patients). Blood samples for measurements of ANP, BNP and NE were drawn in the supine position before the procedure.ANP, BNP and NE levels were greater in patients with persistent AF than in patients with paroxysmal AF (median (25th-75th centile)=28 (18-49) vs 69 (36-106), p0.0001; 28 (15-50) vs 94 (39-156), p0.0001; and 315 (223-502) vs 382 (299-517) pg/mL, p=0.04, respectively). NE level correlated weakly with ANP and BNP levels (r=0.28 and r=0.23, respectively, p0.01 for both). BNP and NE levels differed between patients with and without recurrence of AF (55 (26-135) vs 35 (18-64), p=0.005 and 431 (323-560) vs 302 (225-436) pg/mL, p0.001, respectively). Of note, only NE level was significantly greater in patients with symptomatic sick sinus syndrome (SSS) (n=21) than in those without SSS (560 (466-632) vs 321 (242-437) pg/mL, p0.0001). Logistic regression analysis showed NE level to be the only independent discriminator for SSS (OR 1.006, 95% CI 1.002 to 1.010, p=0.001).An increase in plasma NE level was observed in patients with AF and SSS. Although this implies a pathophysiological link between clinical manifestation of SSS and the autonomic nervous dysfunction, further studies are needed to clarify the mechanisms for this novel finding.

Aims Non-contrast T 1-weighted imaging (T1WI) has emerged as a novel non-invasive imaging for vulnerable coronary plaque showing a high-intensity plaque (HIP). However, the association between HIP and percutaneous coronary intervention (PCI) has not been evaluated. We investigated the association between the presence of HIP and the incidence of myocardial injury after PCI. Methods and results A total of 77 patients with stable angina were imaged with non-contrast T1WI by using a 1.5 T magnetic resonance system (HIP and non-HIP group, N = 31 and 46 patients, respectively). We defined HIP as a coronary plaque to myocardium signal intensity ratio (PMR) of ≥1.4. High-sensitive cardiac troponin-T (hs-cTnT) was measured at baseline and 24 h after PCI. Percutaneous coronary intervention-related myocardial injury (PMI) was defined as an elevation of hs-cTnT >5× 99th percentile upper reference limit. High-intensity plaque was associated with the characteristics of ultrasound attenuation and positive remodelling on intravascular ultrasound. Although baseline hs-cTnT was similar between the groups, increase in hs-cTnT was significantly greater in the HIP vs. non-HIP group (0.065 [0.023–0.304] vs. 0.017 [0.005–0.026], P < 0.001). Percutaneous coronary intervention-related myocardial injury occurred more frequently in the HIP than non-HIP group (58.1 vs. 10.9%, P < 0.001), and the cut-off value of PMR found to be 1.44 for predicting PMI (sensitivity 78.3% and specificity 81.5%). In multivariate analysis, a PMR of ≥1.4 was a significant predictor of PMI (odds ratio 5.63, 95% confidence interval 1.28–24.7, P = 0.022). Conclusion High-intensity plaque on non-contrast T1WI was characterized as vulnerable coronary plaque on IVUS and was associated with higher incidence of PMI.

BackgroundThe association of Mehran risk score (MRS) with long-term prognosis in patients treated with percutaneous coronary intervention (PCI) has not been fully reported. We investigated the association between MRS and clinical outcomes in patients who underwent PCI.MethodsStudy subjects comprised 2198 patients treated with PCI from the Ibaraki Cardiovascular Assessment Study multicenter registry, excluding patients receiving hemodialysis or who died within 7 days. We categorized them into 4 groups according to MRS (low-risk: ≤5; medium-risk: 6–10; high-risk: 11–16; and very high-risk: ≥16). Contrast-induced acute kidney injury (CI-AKI) was defined as an increase of 0.5mg/dL or 25% in pre-PCI serum creatinine within 1-week post procedure. We evaluated CI-AKI and major adverse cardiac and cerebrovascular events (MACCE), and defined as all-cause death, myocardial infarction, congestive heart failure, or cerebrovascular disorder (stroke or transient ischemic attack).ResultsA total of 192 (8.7%) patients developed CI-AKI. At multivariate analysis, odds ratio for CI-AKI was 4.09 (95% CI: 1.72–9.17, p=0.002) in the very high-risk group, 1.49 (95% CI: 0.89–2.42, p=0.120) in the high-risk group, and 1.08 (95% CI: 0.74–1.54, p=0.693) in the medium-risk group, as compared with the low-risk group. MACCE in the very high-risk group was more than 5-fold higher [hazard ratio (HR) 5.40, 95% CI: 2.96–9.28, p

We report a successfully treated case with interstitial pneumonitis due to Otsu-ji-to. Otsu-ji-to contains Ou-gon, an extract of Scuttelaria roots, which is called scullcap in western countries. In Western traditional herbal medicine, scullcap is also utilized for convulsions, hysteria, nervous tension, and epilepsy. A 53-year-old man was admitted for diffuse ground-glass opacity in both lungs noted on a chest X-ray. He had had hemorrhoid 1 month previously, which was successfully treated with surgery. In his postoperative course, he had Otsu-ji-to 7.5 g/day orally. Two weeks after the initiation of the drug, he developed shortness of breath, and was dyspneic at rest. Chest CT showed bilateral diffuse ground-glass opacities in both lungs, but honeycombing and traction bronchiectasis were not observed on it. There was no finding of heart failure or an evidence of pulmonary embolism. The radiological features seemed compatible with acute interstitial pneumonitis. An echocardiogram was normal. Laboratory data showedWBC 10,500/mm, LDH 357 U/L, C-reactive protein 9.46 mg/dl. There was no elevation of antibody titers of Mycolasma, Legionella pneumophilia, and Chlamydia psittaci. Antibiotic treatment was initiated with ciprofloxacin on admission, however, his respiratory status rapidly deteriorated. Suspecting Otsuji-to-induced pneumonitis, it was discontinued and the patient was treated with methylprednisolone (500 mg/day) for 3 days. A lung biopsy was planned but the patient's respiratory condition improved

BackgroundFew studies have examined the association between blood urea nitrogen (BUN) and mortality in patients with coronary artery disease (CAD). We investigated the prognostic value of BUN concentration at hospital admission in patients with CAD.MethodsA total of 3641 patients with CAD who underwent percutaneous coronary intervention (PCI) were included from April 2007 to June 2011. We measured BUN concentration at hospital admission and compared it with long-term clinical outcome. Patients were classified into three groups according to BUN concentration of < 20 mg/dl, 20 to 25 mg/dl, or > 25 mg/dl. Primary endpoint was all-cause death.ResultsDuring the follow-up period (median 15 months), 248 (6.8%) patients died. A higher BUN level was associated with multivessel disease, lower ejection fraction, lower systolic blood pressure, and higher prevalence of comorbidities. Cox regression analysis showed that patients with BUN of > 25 mg/dl had a hazard ratio (HR) for mortality of 2.73 (95% CI, 1.14 to 6.53; p = 0.023) with an estimated glomerular filtration rate (eGFR) of ≥ 45 ml/min/1.73 m2 and a HR of 2.90 (95% CI, 1.75 to 4.82; p < 0.001) with an eGFR of < 45 ml/min/1.73 m2. Regardless of acute coronary syndrome or stable CAD, BUN of > 25 mg/dl was independently associated with higher mortality (HR, 2.58; 95% CI, 1.43 to 4.64; p = 0.004 and HR, 2.16; 95% CI, 1.01 to 4.59; p = 0.044, respectively).ConclusionsA BUN of > 25 mg/dl was associated with long-term mortality in CAD patients who underwent PCI independent of traditional cardiovascular risk factors and eGFR.

Background and purposeThere are a few retrospective subgroup analyses or registries of large-vessel (≥3.5mm) stenting. We investigated clinical outcomes of patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) and bare-metal stents (BMS) in large coronary vessels.Methods and subjectsOf 1100 STEMI patients registered in the Ibaraki Cardiovascular Assessment Study (ICAS) multicenter registry from April 2007 to June 2012 who underwent PCI, we enrolled 454 patients (65.8±12.7 years old, 81% male) with ≥3.5-mm stents. We excluded 53 patients with cardiogenic shock or left main trunk lesions. The remaining 401 patients were divided into Group-D, PCI with DES (n=184), and Group-B, PCI with BMS (n=217). Propensity score analysis matched 1:1 according to treatment with DES (n=101) or with BMS (n=101). We evaluated major adverse cardiac and cerebrovascular events (MACCE) and incidence of stent thrombosis (ST). MACCE was defined as all-cause death, myocardial infarction (MI), target-vessel revascularization (TVR), or cerebrovascular accident (CVA).Essential resultsDuring a mean follow-up period of 526 days, all-cause death, MI, CVA, MACCE, and ST were not significantly different in Group-D versus Group-B (all-cause death: 4.35% vs. 4.61%, p=0.90; MI: 0% vs. 0%; CVA: 2.72% vs. 3.23%, p=0.76; MACCE: 15.2% vs. 20.3%, p=0.19; and ST: 0.0% vs. 1.38%, p=0.11).
