Introduction: Hypertension has been established as one of the most significant causes of heart failure. Left ventricular function is a useful measure in the assessment and prognostication of heart disease.
Aim: To determine the prevalence of Left Ventricular Systolic Dysfunction (LVSD) in hypertensive patients and assess the echocardiographic characteristics associated with LVSD.
Materials and Methods: After obtaining informed consent, 650 eligible adults of age =18 years attending cardiology OPD diagnosed to have essential hypertension with or without medication were included in the study. Using a predesigned structured questionnaire, details of demographic characteristics and echocardiographic data were obtained from the study participants.
Results: The prevalence of LVSD was 136 (20.9%) in the study population {mild LVSD 78 (12%), moderate LVSD 40 (6.2%), severe LVSD 18 (2.8%)}. In Analysis of Variance (ANOVA), variables such as blood pressure, body surface area, size of left atrium and ventricle, relative wall thickness, stroke volume, left ventricular mass index, diastolic function, ejection fraction, fractional shortening were significantly associated with moderate-severe LVSD.
Conclusion: Higher prevalence of LVSD among hypertensive subjects in this study advocates for use of echocardiography as part of routine evaluation in hypertensive patients.
