Abstract
ABSTRCT
Background and Aim of the work
The finding of a dilated and diffusely hypokinetic left ventricle occasionally constitutes a challenge in the daily medical practice as far as the identification of the etiology of this finding is concerned. Additionally, the coronary and carotid arterial tree share all the factors predisposing to atherosclerosis. The ultrasound examination is reliable and easy to use in order to identify carotid disease. Stress echocardiography is a well-established method for the identification of stress-induced wall motion abnormality (WMA) secondary to coronary artery disease. Additionally, the identification of stress-induced WMA may also help differentiate ICMP from NICMP by examination of Dobutamine Stress Echocardiography at high dose.
Aim of the Work: to evaluate the sensitivity of Dobutamine stress echocardiography and carotid artery ultrasound in correlation with coronary angiography in the distinction between ischemic and non-ischemic dilated cardiomyopathy.
Patients and Methods: This study included (76) consecutive patients with signs and symptoms of heart failure of non-identifiable cause.
1-Patients who had echocardiographically diagnosed myopathic dilated left ventricle, EF ≤ 35% with patches of SWMA not correlated with definite coronary artery disease territory.
2-Patients who had echocardiographically diagnosed myopathic dilated left ventricle with global hypokinesia, EF ≤ 35%.
Results: We did correlation between the results of Dobutamine stress echocardiography and carotid artery ultrasound based on confirmation from coronary angiography and we found that, sensitivity was increased to 94% with Specificity 73%.
Conclusions: The correlation between Dobutamine stress echocardiography and Carotid Ultrasound in distinction between Ischemic and Non-Ischemic cardiomyopathy was achieved with high sensitivity.
