Doppler-derived myocardial performance index: a new predictor for subclinical dysfunction in hypertensive patients

ABSTRACT

This study included 40 hypertensive patients and 20 normal subjects as a control group. They were subjected to complete clinical examination, ECG and complete echo-Doppler study with the calculation of Doppler-derived interval index [ICT + IRT]. The index was significantly higher in hypertensive patients as compared with the control, it was also significantly higher in hypertensive patient with eccentric LVH as compared with those with concentric LVH. The index was higher in patients with decreased EF and FS. The Doppler-derived index of combined systolic and diastolic function was higher in hypertensive than normotensive and it may be considered a simple accurate parameter for the detection of subclinical dysfunction and follow up studies of cardiac patients
