Abstract

Dobutamine Stress Echocardiography (DSE) has been proven to be an accurate diagnostic tool in the evaluation of patients with known or suspected coronary artery disease. However, the long term prognostic value of a normal study has not been well established. Methods: Clinical follow-up was obtained in 504 patients who had normal studies with no baseline or stress-induced wall motion abnormalities. Events were categorized as non-cardiac events, hard cardiac events (cardiac death or myocardial infarction) or soft cardiac events (angioplasty, bypass grafting or congestive heart failure) Results: The mean age was 57 years and there were 209 men During a mean follow-up of 50.4 months (range 2-99 months), there were 168(33%) events including 108(21%) non-cardiac deaths and 60(12%) cardiac events. The mean time to any cardiac event was 44 months. There were 34 hard events ( 11 cardiac deaths, 23 non-fatal MI) and 26 soft events (17 revascularizations, 9 CHF). Five year survival free of hard events was 92% by Kaplan-Meier analysis. (Figure Presented) The risk for any cardiac event was 0.28% per patient-year with lhe risk for cardiac death or MI of 0 16% per patient-year. Conclusion: The long term prognosis in patients who have a normal DSE study is good.
