BACKGROUND: There is substantial variability among hospitals in critical care unit (CCU) utilization for patients admitted with non-ST-Segment Elevation Acute Coronary Syndromes (NSTE ACS). We estimated the potential cost saving if all hospitals adopted low CCU utilization practices for patients with NSTE ACS. METHODS: National hospital claims data were used to identify all patients with a primary diagnosis of NSTE ACS initially admitted to an acute care hospital between 2007 and 2013...

Risk stratification of patients with acute myocardial infarction (AMI) is of clinical significance. Although there are many existing risk scores, periodic update is required to reflect contemporary patient profile and management. The present study aims to develop a risk model to predict in-hospital death among contemporary AMI patients as soon as possible after admission. We included 23417 AMI patients from China Acute Myocardial Infarction (CAMI) registry from January 2013 to September 2014 and extracted relevant data...

BACKGROUND: Monitoring anticoagulation with activated clotting time (ACT) has been proposed to reduce ischemic or bleeding events. However, the value of using ACT to improve outcomes is uncertain. This study sought to determine the relationship between ACT and outcomes during percutaneous coronary intervention in patients with non-ST-segment-elevation acute coronary syndrome (NSTE-ACS) treated by unfractionated heparin with GPIs (glycoprotein IIb/IIIa inhibitors). METHODS AND RESULTS: From the randomized TAO trial (Treatment of Acute Coronary Syndromes With Otamixaban), we analyzed the value of ACT to predict ischemic and bleeding outcomes in the 3275 patients receiving unfractionated heparin plus eptifibatide...

BACKGROUND: Defensive coping (DefS) was associated with cardiovascular disease (CVD) susceptibility in Blacks. Whether coping strategies will associate with sub-clinical left ventricular hypertrophy (electrocardiographic-left ventricular hypertrophy [ECG-LVH] or Cornell product), cardiomyocyte injury and blood pressure (BP), is unclear. Therefore, we assessed relationships between ECG-LVH, cardiac troponin T (cTnT) and 24-hour BP in bi-ethnic groups when habitually utilising a certain coping style, and these groups when having a stress-related cTnT cut-point of 4...

Background: Females with ST-segment elevation myocardial infarction (STEMI) have higher in-hospital and short-term mortality rates compared with males in China, suggesting that a sex disparity exists. The age of onset of STEMI is ahead of time and tends to be younger. However, there are relatively little data on the significance of sex on prognosis for long-term outcomes for adult patients with STEMI after percutaneous coronary intervention (PCI) in China. This study sought to analyze the sex differences in 30-day, 1-year, and long-term net adverse clinical events (NACEs) in Chinese adult patients with STEMI after PCI...

Background: Very few data have been reported for ST-segment elevation myocardial infarction (STEMI) caused by unprotected left main coronary artery (ULMCA) occlusion, and very little is known about the results of this subgroup of patients who underwent primary percutaneous coronary intervention (PCI). The aim of this study was to determine the clinical features and outcomes of patients with STEMI who underwent primary PCI for acute ULMCA occlusion. Methods: From January 2000 to February 2014, 372 patients with STEMI caused by ULMCA acute occlusion (ULMCA-STEMI) who underwent primary PCI at one of two centers were enrolled...

BACKGROUND: To determine whether nicorandil administration distal to the thrombus in the coronary artery during percutaneous coronary intervention (PCI) in acute ST-segment elevation myocardial infarction (STEMI) patients reduced the incidence of no-reflow phenomenon, reperfusion injury, and adverse events. METHODS: This randomised controlled trial involved 170 STEMI patients who underwent PCI. All patients underwent thrombectomy and tirofiban injection (10μg/kg) distal to the vascular lesion via a suction catheter, followed by nicorandil (84 patients; 2mg) or saline injection (86 patients; 2mL) at the same site...

BACKGROUND: There are few published studies of ST-segment elevation myocardial infarction (STEMI) in younger individuals. The differences between these "younger" and "older" individuals may not be fully appreciated by clinicians. The aim of this study was to determine the reasons for the earlier presentation and help to identify strategies for prevention of recurrent myocardial infarction (MI) in younger patients. METHODS: The study population was a cohort of 2,419 consecutive STEMI patients who were treated with primary percutaneous coronary intervention...

The presence of carotid atherosclerosis accompanied by coronary artery disease is associated with poor prognosis. A subset of patients who take aspirin continue to have recurrent cardiovascular events, which may be due to aspirin resistance (AR). Also, carotid plaques may cause turbulent flow which in turn may lead to platelet activation and poor antiplatelet response. In our study, we aimed to show the prevalence of AR and its relationship between high-risk carotid images in young patients with ST-segment elevated myocardial infarction (STEMI)...

Trimetazidine (TMZ) is a metabolic agent with significant anti-ischemic properties. By inhibiting the terminal enzyme in the β-oxidation pathway, it shifts the energy substrate metabolism, enhancing glucose metabolism. Thus, it maintains the required energy production with less oxygen consumption, an effect necessary in cases of myocardi. Trimetazidine was recently reaccredited as add-on therapy for symptomatic treatment in patients with stable angina, not adequately controlled or intolerant to first-line therapy...

AIMS: ST-segment elevation myocardial infarction (STEMI) is an acute inflammatory and thrombotic disease due to coronary artery atherosclerotic lesions. Studies have established the correlation of serum sulfatides with inflammation, thrombogenesis, and atherosclerosis. We observed that serum sulfatides level significantly increased in STEMI patients. In this study, we try to identify the relationship of serum sulfatides level on clinical outcomes of patients in STEMI. METHODS: Serum sulfatides level was monitored in 370 inpatients within 24 h of STEMI onset...
