Myocardial revascularization for chronic stable angina. Analysis of the role of percutaneous transluminal coronary angioplasty based on data available in 1989.
TL;DR: A decision analytic model suggests that angioplasty is a reasonable alternative to bypass surgery in patients with favorable lesions if angiopLasty would provide a comparable degree of revascularization, and predicts that both treatments will cost the same over the typical patient's lifetime.

A quality assurance model of operative mortality in coronary artery surgery
Fred H. Edwards,Fred H. Edwards,Fred H. Edwards,Robert A. Albus,Robert A. Albus,Robert A. Albus,Rostik Zajtchuk,Rostik Zajtchuk,Rostik Zajtchuk,Geoffrey M. Graeber,Geoffrey M. Graeber,Geoffrey M. Graeber,Michael J. Barry,Michael J. Barry,Michael J. Barry +14 more
TL;DR: The results illustrate the fallacy of using raw mortality statistics for interinstitutional comparisons and develop a risk model of accepted CABG mortality and illustrate its proper use in coronary artery surgery.
Journal ArticleDOI
Bypass surgery for chronic stable angina: predictors of survival benefit and strategy for patient selection.
TL;DR: Patients are likely to live longer after CABG if they have left main disease; three-vessel disease with left ventricular dysfunction, class III or IV angina, provocable ischemia, or disease in the proximal left anterior descending coronary artery.
Journal ArticleDOI
Effect of Crossover on the Statistical Power of Randomized Studies
TL;DR: It is demonstrated that crossover may have a profound effect on the statistical power of randomized studies and a method for predicting the effect of such crossover on statistical power is presented.

Clinical and operative characteristics of patients randomized to coronary artery bypass surgery in the bypass angioplasty revascularization investigation (BARI)
Hartzell V. Schaff,Allan D. Rosen,Richard J. Shemin,Y Leclerc,T. H. Wareing,Frank V. Aguirre,George Sopko,T. J. Vandersalm,Floyd D. Loop +8 more
TL;DR: The surgical cohort of the Bypass Angioplasty Revascularization Investigation (BARI) is the largest group of patients with multivessel coronary artery disease randomly assigned to surgical treatment and some aspects of the variability in surgical practice are described.

TL;DR: This report is the first simple account yet published for non-statistical physicians of how to analyse efficiently data from clinical trials of survival duration, and it may be preferable to use these statistical methods to study time to local recurrence of tumour, or toStudy time to detectable metastatic spread, in addition to studying total survival.
Journal ArticleDOI
Coronary artery surgery study (CASS): a randomized trial of coronary artery bypass surgery. Survival data.
TL;DR: Patients similar to those enrolled in this trial can safely defer bypass surgery until symptoms worsen to the point that surgical palliation is required.
Journal ArticleDOI
Coronary artery surgery study (CASS): a randomized trial of coronary artery bypass surgery. Quality of life in patients randomly assigned to treatment groups.
TL;DR: This randomized collaborative study shows that coronary artery bypass graft surgery improves the quality of life as manifested by relief of chest pain, improvement in both subjective and objective measurements of functional status, and a diminished requirement for drug therapy.

Declining cardiovascular mortality.
William B. Kannel,T J Thom +1 more
TL;DR: Improvement in cardiovascular mortality is the main reason that total mortality has declined 26% since 1963 and that average life expectancy at age 35 increased 2.6 years during the 10 years from 1972 to 1982, a greater increase than during any decade since vital statistics were first published in 1900.
