Prognostic value of extensive coronary calcium quantities in symptomatic males--a 5-year follow-up study.

摘要: Aims Coronary calcium scores (CSs) have been shown to predict future events in patients presenting for first-time evaluation of CAD. Long-term outcome data on symptomatic subjects with advanced CAD are limited. In this study, we evaluated the prognostic value very high coronary CSs males undergoing angiography and analyzed impact event definitions identification risk predictor’s. Methods results Fifty consecutive electron beam computed tomography (EBT)-based >1000 were matched 1:2 by age between 400–1000 100–400. All 150 underwent angiography. factors ascertained. Events after 5 years for: (1) hard (coronary death myocardial infarction); (2) overall (adding stroke non-coronary deaths); (3) all (including long-term revascularizations). During follow-up, 17 deaths, two infarctions three strokes occurred 21 patients; 38 43 revascularizations. earlier more frequently >1000. Left main disease was only independent predictor (hazard ratio, 4.5; 95% confidence interval, 1.1–17.8). (4.3; 1.4–13.0) (1.7; 1.1–2.5) independently predicted events. Only CSs>90thpercentile (2.5; 1.3–4.8). Conclusions Symptomatic extensive carry an even higher than other these patients, EBT-based calcified plaque burden angiographic indices severity may a complementary role predicting cardiovascular
