The angiographic findings of 930 men and 257 women who were referred to a Los Angeles County hospital from 1972 through 1981 are compared. Chi square test results indicated triple-vessel disease was more common in men (37.1%) compared with women (18.7%). The prevalence of normal angiographic findings was higher in women (23.3%) than in men (8.1%). However, for men and women with evidence of coronary artery disease, virtually identical percentages of subjects had left main, single-, double-, and triple-vessel disease. Although the incidence of coronary artery disease decreased during this time for the Los Angeles population as a whole, no differences in patterns of coronary vessel lesions were evidenced.
