Abstract :

Objective: In asymptomatic and incidentally detected low ejection fraction patients, performing a coronary angiography (CAG) is not recommended routinely. But the prognosis for patients with ischemic etiology remains worse and performing CAG for the elucidation of the etiology may be beneficial. In our study, in asymptomatic and low EF patients who underwent CAG, coronary artery disease frequency was investigated. Methods: Totally 100 coronary angiography were performed at our institution for the elucidation of the etiology. The patients do not have angina or heart failure symptoms. Results: The median age was 61 years with 75% male ratio. Mean ejection fraction was 33.8%. Ischemic etiology was 26% after coronary angiography. The prevalence of CABG was 8 and stenting was 11 patients, CABG and stenting group was defined as invasive therapy group with 19 patients. The prevalence of normally coronary artery was 17. The prevalence of medical therapy decision was 64 patients. The medical therapy patients were divided into two groups. 7 patients were in ischemic group and 57 patients were in non-ischemic group. Conclusion: In our study, in patients without chest pain or symptoms of heart failure with low ejection fraction, incidence of coronary artery disease were evaluated.
