Aortocoronary bypass: early results of operations in community hospitals of greater New Orleans.

All 588 aortocoronary bypass operations performed in the community hospitals of greater New Orleans before 1974 are reported. Hospital mortality averaged 8.7% (4.3% for one bypass; 6.4% for two; 10.3% for three or more; 26% when bypass was combined with another cardiac procedure). Mortality ranged from 5% to 31% among ten surgical groups and from 0 to 20% among seven community hospitals. Men over 60 had excessive mortality (25%). The incidence of major nonfatal complications (myocardial infarction in 12.8% of patients, intraventricular conduction defects in 9.6%, significant arrhythmias in 10.7%, and complications requiring reoperation in 9.5%) also varied with the surgical group, the complexity of the procedure, the patient's age, and the hospital. As determined by these four factors, results of bypass operations in the community hospitals of greater New Orleans ranged from excellent to poor.

A study of serum lipoproteins and angiographic evidence of coronary artery disease.

Extensive serum lipid analyses, with specific emphasis on the concentration of serum beta and pre-beta-lipoproteins, were made on 93 patients who had a clinical diagnosis of angina pectoris and were undergoing coronary angiographic studies. Those individuals with abnormal angiographic evidence of obstructive coronary artery disease, including a group with a prior myocardial infarction, have almost uniformly elevated serum beta-lipoprotein levels when related to an arbitrary division based on the mean values for a "normal" adult population at a similar age level. Compared to serum cholesterol and serum triglycerides, the serum lipoprotein concentrations, specifically beta-lipoproteins, appear to be a more useful parameter for predicting the existence of coronary artery disease. Further studies relating clinical risk factors to coronary artery disease might be better approached by using angiography of coronary vessels rather than myocardial infarction or sudden death from coronary artery disease as an endpoint of morbid data.
