ABSTRACT
BACKGROUNDS Ischemic cardiomyopathy in the elderly bears a worse prognosis than non-ischemic cardiomyopathy, and may show an improved outcome after myocardial revascularization. The noninvasive techniques which can reliably distinquish between ischemic and non-ischemic cardiomyopathy have been tested. As ultrasonographically assessed carotid atherosclerosis is being used as a surrogate measure of coronary atherosclerosis, non studies to date have used carotid atherosclerosis to distinguish between ischemic and non-ischemic cardiomyopathy in the elderly. METHODS:
One hundred forty eight patients(61 women, 87 male) greater than 65 years of age who have dilated cardiomyopathy with left ventricular enddiastolic inner dimension 55mm and fractional shortening 25% were evaluated by B-mode ultrasound imaging of carotid artery for measurement of atherosclerotic plaque. Also coronary angiography was done, and ischemic cardiomyo- pathy was defined as the presence of any 2 or more epicardial coronary vessels with 75% stenosis. and then the value of carotid athe rosclerosis in the distinction between ischemic and non-ischemic etiology in the elderly with dilated cardiomyopathy was examined.RESULTS:
Ischemic etiology of dilated cardiomyopathy in the elderly can be defined as the presence of carotid atherosclerosis with 25% stenosis. Carotid stenosis 25% had sensitivity 82.5%(74% in women, 91% in male), specificity 85.5%(92% in women, 79% in male), positive predictive value 90.5%(93% in women, 88% in male) and negative predictive value 78.5%(73% in women, 84% in male) as whole in the identification of patients with ischemic cardiomyopathy.CONCLUSION:
Carotid stenosis by B-mode ultrasonography is noninvasive and useful in the distinction between ischemic and nonischemic etiology in the elderly patients with clinically unexplained cardiomyopathy
