Left ventricular hypertrophy (LVH) has prognostic significance on cardiovascular mortality and morbidity. However, echocardiography screening for LVH is not routinely done for hypertensive patients in a primary care setting. Thus, this quantitative study aims to determine the prevalence and factors associated with LVH in hypertensive patients at a primary care setting. This was a cross-sectional study of 359 consecutive patients with uncomplicated essential hypertension attending a hospital-based clinic

in Malaysia. All subjects underwent an echocardiography test. LVH occur when the left ventricular posterior wall thickness together with inter-ventricular septal thickness is ≥11 mm. It was found that 24% patients fulfilled the criteria for LVH. The mean age of the study population was 59.2}7.7 years; mean duration of hypertension was 9.7}7.5 years; and mean blood pressure was 136.5/81.5 (}13.7/7.7) mmHg. Using multiple logistic regression analysis, patients who were obese [odds ratio (OR) 8.34, 95% confidence interval (CI) 3.14, 22.22] and male gender (OR 1.96, 95% CI 1.08, 3.16) had significant positive association with LVH. LVH was found in approximately one fourth of the hypertensive patients at a hospital-based primary care setting. There was a significant positive association between LVH and obesity and being male. Guidelines for enhancing use of echocardiography in detecting LVH may be needed.
