Why the study?
Speckle tracking emerged as a new diagnostic tool, but its role in ischemic cardiomyopathy was not well addressed.
Does two-dimensional speckle tracking imaging detect right ventricular dysfunction in patients with ischemic cardiomyopathy compared to healthy controls?
Does two-dimensional speckle tracking imaging detect right ventricular dysfunction in patients with ischemic cardiomyopathy compared to healthy controls?
Speckle tracking echocardiography may be useful in assessing right ventricular function in patients with ischemic cardiomyopathy.
Higher LV Tei index in ICM patients supports further speckle tracking evaluation; leaves open its utility for RV dysfunction assessment.
Background: Ischemic cardiomyopathy [ICM] refers to the reduced pumping ability of the heart due to damage of myocardium as a result of ischemia. Thus, early detection of coronary artery disease could save the myocardium. Speckle tracking emerged as a new diagnostic tool, but its role in ischemic cardiomyopathy is not well addressed. Aim of the work: To assess right ventricle [RV] function by two-dimensional [2D] speckle tracking imaging in patients with ICM. Patients and Methods: This study included 38 patients with ICM and 30 healthy subjects as a control group. Conventional echo-Doppler parameters of right ventricular function together with tissue Doppler imaging derived RV strain and speckle-tracking echo-derived RV global strain [STE-RVGST] were addressed. Results: The two groups were matched in age and sex. ICM had significantly higher values of LV Tei index [0.90±0.28] versus control group [0.51±0.13] with p value
