Abstract

Hypertension is the major cause of congestive cardiac failure all over the world. It is under diagnosed and achievement of optimal therapy is difficult and costly.
Diastolic dysfunction is an early poor prognostic factor in hypertension and is a reversible condition. Early detection and treatment is necessary to avoid cardiac
complications. The objective of this study was to assess the occurrence of diastolic dysfunction in hypertensive patients referred for echocardiograph assessment of
left ventricular function in a secondary hospital. It was also designed to determine whether contributing factors such as age, gender, systolic and diastolic pressure,
duration of hypertension, previous myocardial infarct or ischemic heart disease and choice of anti-hypertensive drugs influence the development of diastolic dysfunction in these hypertensive patients. The analysis of diastolic dysfunction was based on the E/A ratio using Doppler echocardiogram. All of the patients were recruited from the Echocardiography Unit, Department of Medicine, Seremban General Hospital. Fifty patients with history of hypertension were selected for the study. Out of These 22 patients (44%) were found to have diastolic dysfunction; 39.1% of male patients (9 out of 23) and 48.1% of female patients (13 out of 27). Other contributing factors of diastolic dysfunction were found in patients: (a) with more than 8 years history of hypertension (12%) (b) with history of preexisting IHD/AMI (20%), (c) stages II – III of systolic hypertension based on 6th Joint National Committee recommendation (73%) (d) on ACE-inhibitor (18%)
and (e) on Beta-blocker (28%) In conclusion, the study had demonstrated that the duration of hypertension, both systolic and diastolic blood pressure and age of patients are important prognostic indicators in predicting the development of diastolic dysfunction in hypertensive patients.
