Does direct coronary arterial revascularization improve outcomes in patients with ischemic cardiomyopathy and cardiac failure?
Does direct coronary arterial revascularization improve outcomes in patients with ischemic cardiomyopathy and cardiac failure?
Direct coronary arterial revascularization in patients with ischemic cardiomyopathy and heart failure carries a notable mortality risk but yields significant clinical and ventricular functional improvement in survivors.
Answers are grounded in this paper and cite their sources.
Notable mortality warrants caution in ischemic cardiomyopathy; hypothesis-generating case data leaves open outcome improvement with revascularization.
Forty patients with ischemic cardiomyopathy and cardiac failure due to coronary artery disease have undergone direct coronary arterial revascularization with a hospital mortality of 15% and late mortality of 7%. Of the 31 survivors, 80% have had good or excellent clinical results with significant improvement in left ventricular function.
