OBJECTIVES The study evaluated the efficacy and safety of a short-acting reduced-dose fibrinolytic regimen to promote early infarct-related artery (IRA) patency during the inherent delay experienced by infarct patients referred for angioplasty as the principal recanalization modality. BACKGROUND Previous approaches using long-acting, full-dose(More)
BACKGROUND Although prior studies have shown a relationship between anemia and in-hospital mortality after coronary artery bypass grafting and acute myocardial infarction (MI), the prognostic implication of anemia in patients undergoing percutaneous coronary intervention (PCI) is unknown. Therefore, we evaluated the relationship between anemia and outcomes(More)
The effects of aerobic training on left ventricular diastolic filling were determined and related to the effects on maximal oxygen uptake, left ventricular systolic function, and left ventricular mass. Nine untrained healthy males with a mean age of 32 years underwent a ten-week program of bicycle training. Echocardiographic left ventricular mass, maximal(More)
BACKGROUND Prasugrel is a recently approved thienopyridine for use in patients with acute coronary syndromes undergoing percutaneous coronary intervention. There are no data on contemporary use of prasugrel in routine clinical practice. METHODS AND RESULTS We assessed the patterns of prasugrel use among 55 821 patients who underwent percutaneous coronary(More)
This study assessed the frequency and types of CAM therapies used by patients hospitalized with acute coronary syndromes for general health purposes and cardiac reasons. We profiled CAM users including gender differences and degree of disclosure with treating physicians'. Data collection occurred via semi-structured interview and included demographics, past(More)
Technetium-99m stannous pyrophosphate (99mTc-PYP) cardiac scintigraphy was performed in 15 rabbits with experimental Streptococcus sanguis aortic valve infective endocarditis. The animals were imaged five to seven days after the administration of bacteria, and in each case abnormal accumulation of the tracer was visualized in the region of the aortic valve.(More)
OBJECTIVES We sought to assess the impact of the American College of Cardiology's Guidelines Applied in Practice (GAP) project for acute myocardial infarction (AMI) care, encompassing 33 acute-care hospitals in southeastern Michigan, on rates of mortality in Medicare patients treated in Michigan. BACKGROUND The GAP project increases the use of(More)
BACKGROUND The American College of Cardiology's Guidelines Applied in Practice (GAP) initiative for acute myocardial infarction (AMI) has been shown to increase the use of guideline-based therapies and improve outcomes in patients with AMI. It is unknown whether hospitals that are more successful in using the standard discharge contract--a key component of(More)
Forty-five patients with chronic aortic regurgitation (AR) underwent first-pass radionuclide angiocardiography (RNA) at rest and during upright bicycle exercise, as well as M-mode echocardiography at rest. Abnormal left ventricular (LV) exercise reserve, defined by the absolute change in ejection fraction (EF), was present in 16 of 45 patients (36%). Seven(More)
