It is well known that hypertension is an important cause for diastolic dysfunction. Hence we aimed to evaluate the application of Doppler echocardiography in determining left ventricular diastolic dysfunction in patients with essential hypertension.
Present study is based on analysis of 60 (33 males, 27 females) patients of essential hypertension coming to outpatient department and admitted to S.S. Hospital attached to S.S. Institute of Medical sciences, and Research Centre Davanagere, during January 2013 to December 2013. 60 age and sex matched controls were analysed for diastolic function. Detailed history and physical examination was done. Cases and Controls were subjected to ECG, CXR, USG abdomen, routine investigations and Doppler Echocardiography.
A total of 60 patients were studied. 24 patients showed diastolic dysfunction with E/A ratio <1, with increased atrial filling fraction. Out of 24 (males 15, female 9) patients 15 showed LVH. Out of 36 patients with normal diastolic function (E/A≥1) 9 had LVH. There was significant difference in various diastolic filling parameters in cases with diastolic dysfunction compared to cases with normal diastolic function.
Our findings suggest that myocardial damage in patients with essential HTN affects diastolic dysfunction before systolic dysfunction. LVH was significantly associated with diastolic dysfunction. There was significant difference in various diastolic filling parameters in cases with diastolic dysfunction compared to cases with normal diastolic function.
