Isolated Coronary Ectasia is Associated with Impairment of Left Ventricular Myocardial Performance and Aortic Elastic Properties

Khaled Sayed Mahmoud

Aim: To investigate ventricular functions and tissue Doppler echocardiography-derived myocardial performance index and the elastic characteristics of the aorta in patients with coronary artery ectasia.

Material and methods: 42 patients with coronary artery ectasia ; mean age 56.9 ± 9.1 years and 26 subjects with angiographically normal coronaries; mean age 54.1 ± 6.9 years, were included in the study. All the subjects underwent echocardiography and tissue Doppler imaging to determine left ventricular diastolic functions, myocardial performance index, and elastic characteristics of the aorta

Results: The LV diastolic functions and myocardial permanence were impaired in the ectasia group as compared with patients with normal coronary arteries. The values obtained for aortic elasticity, as aortic strain, β index and aortic distensibility were lower in the ectasia group when compared with the values of the normal group

Conclusion: Left ventricular myocardial performance index, and elasticity of the aorta were deteriorated in patients with isolated coronary ectasia.
