In patients with unstable angina and non-ST elevation myocardial infarction (UA/NSTEMI) two strategies are possible, either a routine invasive strategy where all patients undergo coronary angiography shortly after admission and, if indicated, coronary revascularization; or a conservative strategy where medical therapy alone is used initially, with selection of patients for ...

Oxygen (O(2)) is widely recommended for patients with myocardial infarction yet a narrative review has suggested it may do more harm than good. Systematic reviews have concluded that there was insufficient evidence to know whether oxygen reduced, increased or had no effect on the heart ischaemia or infarct size. To ...

Although ST-segment depression (STD) on the admission electrocardiogram (ECG) confers adverse prognosis in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS), the implications of STD on follow-up ECG remain uncertain. We determined the prognostic significance of STD on follow-up ECG performed within 12-24 h of admission and whether its quantitative ...

Immediate defibrillation is the traditional approach to resuscitation of cardiac arrest due to ventricular fibrillation or tachycardia (VF/VT). Delaying defibrillation to provide chest compressions may improve survival. We examined the effect of the duration of Emergency Medical Services (EMS) cardiopulmonary resuscitation (CPR) prior to first defibrillation on survival in patients ...

Thoracic endografts (stent grafts) have emerged as a less invasive modality to treat various thoracic aortic lesions. The intentional coverage of the left subclavian artery (LSA) during the placement of these endografts is associated with several complications including stroke, spinal cord ischemia, and arm ischemia. In this review, we synthesize ...

Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) resulted in different degrees of damage to the heart muscle, and yet, when factors related to in-hospital outcomes were examined, these two subsets were often lumped together as non-STelevation acute coronary syndrome. Therefore, we investigated predictors of in-hospital heart failure (HF) in ...

BACKGROUND: The rate of death, including sudden cardiac death, is highest early after a myocardial infarction. Yet current guidelines do not recommend the use of an implantable cardioverter-defibrillator (ICD) within 40 days after a myocardial infarction for the prevention of sudden cardiac death. We tested the hypothesis that patients at ...

Left atrial (LA) size is considered a marker of poor prognosis in heart failure (HF) patients. Prior studies have recruited relatively few subjects limiting their power to adequately analyse the interaction between LA size, left ventricular (LV) systolic and diastolic function, and prognosis. The MeRGE collaboration combines prospective data from ...

BACKGROUND: Hyperglycaemia in the acute phase of stroke has been established as a predictor of higher mortality. But recent data regarding active treatment of hyperglycaemia showed no clinical benefit suggesting that hyperglycaemia may not have a detrimental effect in brain infarction. Additional data are needed to resolve this uncertainty and ...
