INTRODUCTION: Doppler echocardiography can detect early diastolic dysfunction, which is a risk factor for the development of heart failure and death, even in those who are not showing any symptoms.

AIMS & OBJECTIVE: To use the myocardial performance index on Doppler echo to detect early subclinical LV dysfunction.

MATERIAL & METHODS: This cross-sectional study was conducted in Gulab Devi Teaching Hospital, Lahore. Data collected after the approval from hospital’s ethics committee. The research was divided into two groups, the first of which was made up of 50 healthy adult volunteers with normal echocardiograms and no cardiovascular issues. The second group included 45 people who were hypertensive and also had left ventricular systolic dysfunction.

RESULTS: The mean age of the participants in the research was 50 + 5.3 years. Patients had an average age of 47.83 + 5.61 years. The average lifespan of someone with diabetes is between 2.56 and 5.61 years.

CONCLUSION: Examinations of hypertensive individuals having normal ejection fraction using MPI with conventional pulsed-wave & tissue Doppler imaging demonstrated a high level of clinical agreement, but a low degree of diagnostic accuracy for detecting diastolic dysfunction.
