BACKGROUND: The biphasic inflammation after ST-segment elevation myocardial infarction (STEMI) plays an important role in myocardial healing and progression of systemic atherosclerosis. The purpose of this study is to investigate the impact of fever during the first and second phases of post-STEMI inflammation on long-term cardiac outcomes. METHODS AND RESULTS: A total of 550 patients with STEMI were enrolled in this study. Axillary body temperature (BT) was measured and maximum BTs were determined for the first (within 3 days: max-BT1-3d) and second (from 4 to 10 days after admission: max-BT4-10d) phases, respectively...

BACKGROUND: We investigated the association between phosphate and the risk of adverse clinical outcomes in patients with manifest cardiovascular disease (CVD). METHODS: Observational study of patients hospitalized during 2006-2011 in Stockholm, Sweden, because of suspected acute coronary syndrome (ACS). The exposure was serum phosphate during the hospitalization. We modeled the association between phosphate and in-hospital death or in-hospital events (composite of myocardial infarction, cardiogenic shock, resuscitated cardiac arrest, atrial fibrillation, or atrioventricular block) as well as the one-year post-discharge risk of death or cardiovascular event (composite of myocardial re-infarction, heart failure and stroke)...

The aim of this study was to evaluate whether growth differentiation factor-15 (GDF-15) plasma concentration at the time of percutaneous coronary intervention (PCI) might help identify those patients with acute coronary syndrome (ACS), who benefit most from high-dose statin treatment. Two hundred eighty-four consecutive patients, who underwent percutaneous coronary intervention (PCI) for ACS, were included in a prospective registry. The combined end point at 3 months after PCI consisted of cardiovascular death, nonfatal myocardial infarction, and unstable angina...

BACKGROUND: Early stent thrombosis (ST) remains an important complication of primary percutaneous intervention (PCI). To date, our information on angiographic and clinical predictors of early ST in ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI is limited. METHODS: We tried to evaluate the incidence, predictors, and outcomes of early ST in real-world patients treated with primary PCI. We identified all the patients presenting with STEMI between June 2004 and January 2011 who underwent primary PCI as the primary mode of revascularization...

Awareness of care variation and associated differences in outcome quality is important for patients to recognize and leverage the benefits of hospital choice and for policy makers, providers, and suppliers to adapt initiatives to improve hospital quality of care. We examine panel data on outcome quality in German hospitals between 2006 and 2014 for cholecystectomy, pacemaker implantation, hip replacement, percutaneous coronary intervention (PCI), stroke, and acute myocardial infarction (AMI). We use risk-adjusted and unadjusted outcomes based on 16 indicators...

We assessed the efficacy and safety of tirofiban intracoronary versus intravenous administration during percutaneous coronary intervention for patients with acute coronary syndrome. The databases of PubMed, Web of Science, China National Knowledge Infrastructure, and WanFang Database were retrieved. A total of 437 articles were found, according to inclusive and exclusive criteria, 13 of which were finally included. Compared with subjects with intravenous administration, those with intracoronary administration were more likely to reach thrombolysis in myocardial infarction trial grade 3 flow (relative risk = 1...

Kawasaki disease is an acute self-limiting systemic vasculitis. It is the most common cause of acquired heart disease, with the risk of developing coronary artery aneurysms, myocardial infarction and sudden death. Diagnosis is based on the presence of fever in addition to other clinical criteria. The quarter of the Kawasaki disease patients have "incomplete" presentation. Treatment with intravenous immunoglobulin within ten days of fever onset improves clinical outcomes and reduces the incidence of coronary artery dilation to less than 5%...

BACKGROUND: Coronary heart disease is a major cause of heart failure. Availability of risk-prediction models that include both clinical parameters and biomarkers is limited. We aimed to develop such a model for prediction of incident heart failure. METHODS: A multivariable risk-factor model was developed for prediction of first occurrence of heart failure death or hospitalization. A simplified risk score was derived that enabled subjects to be grouped into categories of 5-year risk varying from <5% to >20%...

Myocardial infarction with normal coronary arteries is a well known pathology. It may or may not be associated with left ventricle wall motion abnormalities. Data was reviewed retrospectively for patients with ST elevation myocardial infarction who underwent cardiac catheterization. From the total number of patients evaluated 10.3% (17) patients had Myocardial Infarction with normal coronary arteries. Females were more likely to present with MINCA then males. Coronary flow was normal in 11 from 17 patients with MINCA...

Although the gold standard treatment for acute myocardial infarction is reperfusion therapy, reperfusion itself can cause myocardial damage via induction of cardiac mitochondrial dysfunction. This can lead to increased myocardial infarct size, arrhythmias and left ventricular (LV) dysfunction. Recently, a newly discovered peptide, Humanin, has been shown to exert several beneficial effects including anti-oxidative and anti-apoptosis effects. We recently reported that a Humanin analogue (HNG, 84 μg/kg) given prior to cardiac ischemia exerted cardioprotection against I/R injury, but failed to do so when it was given after ischemia was induced...

BACKGROUND: Bradycardia on presentation is frequently observed in patients with right coronary artery ST-segment elevation myocardial infarction, but it is largely unknown whether it predicts poor angiographic or clinical outcomes in that patient population. We sought to determine the prognostic implications of admission heart rate (AHR) in patients with ST-segment elevation myocardial infarction and a right coronary artery culprit lesion. METHODS AND RESULTS: We analyzed 1460 patients with ST-segment elevation myocardial infarction and a right coronary artery culprit lesion enrolled in the randomized HORIZONS-AMI (Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction) trial who underwent primary percutaneous coronary intervention...
