Background Signal-averaged electrocardiography (SAECG) in patients after myocardial infarction (MI) is widely used to identify patients at risk for ventricular tachycardia (VT) and sudden cardiac death (SCD). It is believed that ventricular late potentials when detected after day 5 after MI are...
Background Accurately establishing prognosis in severe heart failure has become increasingly important in assessing the efficacy of treatment modalities and in appropriately allocating scarce resources for transplantation. Peak exercise oxygen uptake appears to have an important role in risk...
Psychosocial factors, particularly depression and lack of social support, are important predictors of morbidity and mortality in patients with coronary heart disease. This article describes the design and methods of the Enhancing Recovery in Coronary Heart Disease Patients (ENRICHD) study, a...
Background Compared with angioplasty, elective stent implantation has improved short-term and long-term outcome with a decrease in abrupt closure and a reduced 6-month restenosis rate. Although primary angioplasty during acute myocardial infarction has improved outcome, recurrent ischemic events...
Background The accuracy of dobutamine echocardiography (DE) early after reperfused acute myocardial infarction (AMI) without residual stenosis of the infarct-related artery is unknown. The objective of this study was to assess whether in reperfused AMI DE can predict early as well as late...
Background Evidence from numerous studies of coronary angiography show differences between observers’ assessments of 15% to 45%. The implication of this variation is serious: If readings are erroneous, some patients will undergo revascularization procedures unnecessarily and others will be...
Background The purpose of this study was to determine whether immediate suture closure of 8F femoral arterial puncture sites can facilitate same-day discharge after coronary angioplasty. Methods and Results After coronary angioplasty, 100 patients were randomly assigned to immediate sheath...
Background A correlation has been reported between lipoprotein(a) (Lp(a)) concentration and risk for coronary artery disease. High concentrations of Lp(a) might be markers for vascular or tissue injury or might be associated with other genetic or environmental factors that can cause acute...
Background Readmission rates for patients discharged with heart failure approach 50% within 6 months. Identifying factors to predict risk of readmission in these patients could help clinicians focus resource-intensive disease management efforts on the high-risk patients. Methods The study sample...
