N2 - The current exploratory study was aimed at estimating measures of blood pressure variability (BPV) and baroreflex sensitivity (BRS) in a healthy population in the Indian sub-continent. One hundred and forty-two healthy subjects were recruited for the study. Blood pressure (BP) was recorded continuously for 15 min using the Finometer (Finapres Medical Systems, The Netherlands). For offline analysis, Nevrokard cardiovascular parameter analysis (CVPA) software (version 2.1.0) was used for BPV analysis. BRS was determined by spectral and sequence methods. One-way ANOVA and Bonferroni's test were used to compare parameters. Pearson's correlation coefficient was employed to look for possible associations between age and other continuous variables. Out of 196 screened volunteers, 54 were excluded and 142 subjects were grouped based on ages as 10-19 years (group 1), 20-29 years (group 2), 30-39 years (group 3), 40-49 years (group 4), and 50-59 years (group 5). Within groups, body mass index (BMI, p=0.000) and BP (systolic and diastolic) were significantly different. Post hoc analysis showed mean blood pressure (MBP) and diastolic blood pressure (DBP) differing significantly between groups 1 and 4 (p<0.05 for both) along with other cardiovascular parameters. Age correlated positively with BMI and all parameters of BP. Significant gender differences were observed for stroke volume, cardiac output, up BRS, total BRS, peripheral resistance (PR), and aortic impedance. Our study has provided reference values for BPV and BRS in an Indian population. It also indicates age-related neurocardiac imbalance and possible utility of these tests for screening at the start of neurocardiac damage in a healthy population.
