Generally speaking elevated troponin levels are consistent with the diagnosis of acute coronary syndrome and haemodynamically relevant coronary artery stenosis. However, they may also point to minor myocardial injury in other circumstances. Four patients with elevated troponin levels after supraventricular tachycardia without evidence of coronary artery disease and very low risk scores for acut...

BACKGROUND Current guidelines for acute coronary syndrome recommend clopidogrel for an optimal period of 12 months in order to reduce the risk of reinfarction and mortality. Premature clopidogrel discontinuation has been associated with higher rates of rehospitalization, coronary stent thrombosis, and mortality. No data exist regarding the effect of the Medicare Part D coverage gap on medical c...

OBJECTIVE The metabolic syndrome confers an increased risk for cardiovascular morbidity and mortality. The presence of coronary collaterals may have beneficial effects during myocardial ischemia and may improve cardiovascular outcome in patients with coronary artery disease. Impaired collateral formation could be one of the reasons for the increased cardiovascular risk in patients with the meta...

Antiphospholipid syndrome (APS) has the clinical manifestations of systemic vascular thrombotic disorders. Although coronary events are infrequent, they have been described. Early coronary interventions and vein graft bypass frequently failed because of thrombosis. Here we present a case of successful coronary intervention and management of acute coronary syndrome under a strictly controlled co...

INTRODUCTION AND OBJECTIVES Risk stratification in non-ST-elevation acute coronary syndrome makes use of clinical variables that can identify patients at an increased risk of complications. Our objective was to identify clinical variables that predict significant stenosis (i.e., >50%) of the left main coronary artery in high-risk patients who have had a first episode of non-ST-elevation acute c...

A 49-year-old man presenting with ST-elevated myocardial infarction was brought to our emergency department with AL amyloidosis. Baseline coronary angiography showed no significant stenosis of the epicardial coronary arteries, however, coronary artery angiography in response to acetylcholine and coronary flow reserve in response to papaverine were abnormal, which suggested impairment of vascula...

Abstract Coronary artery aneurysms in children were observed as a rare complication associated with coronavirus disease 2019 (COVID-19). This case report describes the severe end of spectrum new multisystem inflammatory syndrome 12-year-old child coronary aneurysms, myocardial dysfunction, and shock, managed successfully extracorporeal membrane oxygenation support immunomodulation therapy. also...
