Natural history of severe proximal coronary artery disease as documented by coronary cineangiography

摘要: Abstract Studying the natural history of patients with severe proximal coronary arterial lesions may assist evaluation revascularization surgery. We reviewed mortality statistics 469 80 to 100 percent occlusive in tree as diagnosed by selective angiography. Only normal or moderately impaired left ventricular function were included study; cardiomegaly, congestive heart failure impairment ventriculography excluded. Follow-up periods ranged from 6 11 years for 178 single vessel disease, 177 double disease and 114 triple disease. Patients isolated anterior descending artery had a 4 average yearly attrition rate year 25.5 (17 69). Those right demonstrated only 2.3 14 (11 77). had, respectively, 41.5 63 rates. Survival was related number vessels involved. significant annual rate. The prognosis improved when good angiographic collateralization present, particularly total occlusion. Functional disability, classified according New York Heart Association criteria, rates proved useful indicator large patient groups. Prior myocardial infarction, location lesion above below major septal perforator main trunk did not alter significantly.
