Cardiac hemodynamic profile and its correlates by Impedance plethysmography in normal individuals of Central India.

Evaluation of hemodynamic profile by impedance plethysmography (IPG) provides functional expression of cardiovascular performance with efficacy of treatment. Objective of this study was to establish normative hemodynamic parameters by IPG. In this cross-sectional study hemodynamic parameters including cardiac output (CO), Stroke volume (SV), left ventricular ejection time (LVET), impedance (Zo) Cardiac index (CI) and Stroke index (SI) of 50 normal individuals in mean age 38.9±15.2 years were evaluated. Mean CO and CI were 4.9±0.8L/min and 3.3±0.7 L/min/m2 respectively. A negative linear co-relation of CI with increasing age and body fat mass was observed. Mean LVET was 336±33ms with a significant positive linear correlation (r = 0.46) with advancing age and body fat mass while a negative linear correlation with BSA. To conclude preliminary normative data of cardiac parameters using IPG, in subjects of central India of different age groups has been presented.
