Abstract

Objectives: This study aimed to assess the incidence of left ventricular hypertrophy (LVH) in hypertensive individuals in Karachi, Pakistan, and to evaluate the effectiveness of antihypertensive therapy in preventing LVH.

Methodology: A total of 200 hypertensive patients were referred from the Cardiac OPD to the Radiology department of Medicare Cardiac and General Hospital, Karachi, for echocardiography. Echocardiographic measurements of cardiac chambers were performed by expert echocardiographers, and left ventricular mass (LVM) was calculated using the formula recommended by the American Society of Echocardiography.

Results: Among the hypertensive patients, 100 had uncontrolled blood pressure (≥140/90 mmHg) while 100 had controlled blood pressure (≤130/80 mmHg). The female-to-male ratio was 3:1, with ages ranging from 21 to 80 years. Patients with uncontrolled hypertension exhibited a higher mean body mass index (29 ± 5 kg/m2) and significantly elevated LVM (mean 154 ± 4 g/m2). Angiotensin receptor inhibitors were the most commonly prescribed and effective antihypertensive agents, either as monotherapy or in combination therapy (60%), demonstrating utility in preventing LVH.

Conclusion: This study highlights a high incidence of LVH in uncontrolled hypertensive individuals compared to those with controlled hypertension. Transthoracic echocardiography emerged as a highly valuable, non-invasive tool for measuring LVM and assessing the effectiveness of antihypertensive therapy.
