title: [Increased HDL-cholesterol level improves the prognosis in patients with coronary vasospasm].
abstract: Cardiovascular events were analyzed in the subset of 49 consecutive patients with vasospastic coronary artery disease who underwent diagnostic coronary arteriography from December, 1987 to March, 1991 to confirm coronary artery spasm during anginal attacks. During the follow-up period (30 +/- 14 months, mean +/- SEM), seven patients had cardiovascular accidents including acute myocardial infarction, unstable angina, and stroke (group A), while the remaining 42 patients were event-free (group B). Current smokers at the end of the follow-up period were more common in group A (71%) than in group B (12%) (p < 0.01). Serum total-cholesterol, low density lipoprotein cholesterol, and triglyceride levels were not significantly different between the two groups before or after the follow-up period. The baseline high-density lipoprotein cholesterol (HDL-C) level also did not differ between group A (32.5 +/- 8.3 mg/dl) and group B (41.0 +/- 12.9 mg/dl). However, the HDL-C level significantly increased during the follow-up period in group B (delta HDL-C 6.1 +/- 9.4 mg/dl) (p < 0.01), but not in group A (delta HDL-C -3.3 +/- 7.2 mg/dl). The HDL-C level at the end of the follow-up period in group A (29.2 +/- 9.0 mg/dl) was significantly lower than in group B (47.1 +/- 11.5 mg/dl) (p < 0.01). Cardiovascular accidents were significantly more common in current smokers (50%) (p < 0.01) than in current nonsmokers (5%) after the follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)
