Although populations referred for coronary angiography are increasingly diverse, there is limited information on artery disease (CAD) prevalence and in-hospital mortality other than predominately white male patients.We examined gender ethnic differences in CAD a prospective cohort of patients angiographic evaluation stable angina (n=375,886) or acute syndromes (ACS; unstable myocardial infarction, n=450,329) at 388 US hospitals participating the American College Cardiology-National...

Abstract This report presents the first year's experience of a totally computerized cardiac catheterization laboratory reporting system, including results and complications invasive interventional procedures. Sixty‐three laboratories reported total 71,916 patients studied between January 1 through December 31,1990. Two previous registry reports have been published. Compared with data acquired by methods, in spite an older sicker population, mortality for diagnostic procedures has remained...

<h3>Context</h3>Despite the widespread use of percutaneous coronary intervention (PCI), appropriateness these procedures in contemporary practice is unknown.<h3>Objective</h3>To assess PCI United States.<h3>Design, Setting, and Patients</h3>Multicenter, prospective study patients within National Cardiovascular Data Registry undergoing between July 1, 2009, September 30, 2010, at 1091 US hospitals.

This prospective series of results and complications coronary arteriography from the Registry Society for Cardiac Angiography Interventions is largest ever reported. Since initial report published in 1982, artery surgery angioplasty have improved therefore older more symptomatic patients are referred arteriography. More now studied by femoral approach, major techniques similar. Despite studying higher-risk patients, remarkably similar to those reported series. Because sicker being studied,...

Background —Thrombosis is a pivotal event in the pathogenesis of coronary disease. We hypothesized that presence blood factors reflect enhanced thrombogenic activity would be associated with an increased risk recurrent events during long-term follow-up patients who have recovered from myocardial infarction. Methods and Results —We prospectively enrolled 1045 2 months after index Baseline tests included 6 hemostatic variables ( d -dimer, fibrinogen, factor VII, VIIa, von Willebrand factor,...

Background —Patients with treated diabetes in the randomized-trial segment of Bypass Angioplasty Revascularization Investigation (BARI) who were randomized to initial revascularization PTCA had significantly worse 5-year survival than patients assigned CABG. This treatment difference was not seen among diabetic eligible for BARI opted select their mode revascularization. We hypothesized that differences patient characteristics, assessed and unmeasured, together selection registry, at least...

Background —The Bypass Angioplasty Revascularization Investigation (BARI) included 4039 patients with multivessel coronary artery disease; 1829 consented to randomization, and 2010 did not but were followed up in a registry. Thus, we can evaluate the outcome of physician-guided versus random assignment percutaneous transluminal angioplasty (PTCA) bypass graft surgery (CABG). Methods Results —We compared baseline features outcomes for PTCA CABG overall registry its predesignated subgroups. We...

We studied the in-hospital mortality and morbidity of 745 patients who had suffered a first myocardial infarction. One hundred twenty-four (16.6%) nontransmural infarction 621 (83.4%) transmural Both groups were similar in distribution age, sex, coronary risk factors. Patients with significantly lower (3% vs 11%, p less than 0.01) prevalence premature ventricular complexes (81% 88%, 0.05).

We studied the in-hospital prognosis of 1105 patients who had their first transmural myocardial infarction; 611 (55.3%) anterior infarction (AMI) and 494 (44.7%) inferior (IMI). Patients with IMI a significantly lower mortality rate (9.1% vs 15.6%, p = 0.0014) prevalences congestive heart failure (39.4% 47.6%, 0.0066), cardiogenic shock ( 8.7% 12.6%, 0.0384) conduction defects (left hemiblock, right bundle branch block intraventricular defect).

Abstract In a 42‐month period, 218 deaths occurred in 222, 553 patients undergoing coronary arteriography (0.098%). Age &gt; 60 years, NYHA Class IV function, presence of left main disease, and ejection fraction &lt; 30% all significantly increased the risk procedure. Sex approach (brachial or femoral) used for catheterization did not affect mortality. Since SCAI report 1982, death rate has dropped high‐risk patients. Low‐risk (NYHA I normal arteries) who died generally were elderly had...
