A family history of coronary artery disease (CAD), especially when the disease occurs at a young age, is a potent risk factor for CAD. DNA collection in families in which two or more siblings are affected at an early age allows identification of genetic factors for CAD by linkage analysis. We performed a genomewide scan in 1,168 individuals from 438(More)
BACKGROUND Atrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all-cause mortality may guide interventions. METHODS AND RESULTS In the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial(More)
BACKGROUND Contrast-induced acute kidney injury (CI-AKI) is associated with increased morbidity and mortality after percutaneous coronary interventions and is a patient safety objective of the National Quality Forum. However, no formal quality improvement program to prevent CI-AKI has been conducted. Therefore, we sought to determine whether a 6-year(More)
A group of 205 patients hospitalized with myocardial infarction 2 to 162 months (mean 66) after bypass surgery and 205 control patients with myocardial infarction were compared and followed up for 34 +/- 25 months after hospital discharge. At baseline the postbypass group contained more men (p less than 0.03) and more patients with previous myocardial(More)
Twenty-three patients were identified as having either coronary stent embolization or misdeployment at our center over a 4-year period. They were matched to an equal number of controls who underwent a stenting procedure but in whom embolization or misdeployment did not occur. Baseline demographic characteristics were similar between the 2 groups. The(More)
The purpose of this study was to analyze angiographic findings, clinical course, and follow-up data on 1,752 patients who underwent protocol cardiac catheterization 18 to 48 hours after enrollment in the Thrombolysis in Myocardial Infarction (TIMI) II pilot and randomized trial: 244 patients (14.0%) had < 60% diameter stenosis in the infarct-related artery(More)
BACKGROUND Patients with coronary artery disease and left ventricular dysfunction (LVD) may have areas of hibernating myocardium that improve functionally after revascularization. Coronary collateral circulation may sustain ischemic, dysfunctional myocardium and favor myocardial recovery after revascularization. We evaluated the effect of angiographic(More)
