Objective: Cardiac diseases have strong association in diabetic and hypertensive subjects. Episode of cardiac deaths are more in diabetic and hypertensive subjects than the normal cohorts. Current diagnostic techniques do not have a preclinical diagnostic capability. Preclinical diagnosis that can control morbidity and mortality rate can be only possible by HRV analysis. The paper proposes correlation study and pathophysiological analysis of the correlation between the Heart Rate Variability (HRV) analysis indices and echocardiogram indices. The purpose of the attempt is to validate HRV analysis results that have preclinical diagnostic ability with the echocardiogram findings.
Methods and subjects: Study is conducted with 27 normal subjects, 39 diabetic subjects with and without myocardial ischemia/infarction and 40 hypertensive subjects with and without diabetes. Data samples are collected from Fortis- S.L. Raheja hospital Mahim (W) Mumbai.
Conclusion: The value of HRV index Heart rate variability i.e. SDNN and echocardiogram index left ventricular ejection fraction (LVEF) are correlated moderately in disease cohort.R2 test (goodness of fit test) index is insignificant showing that SDNN does not predict LVEF.
