CARDIOVASCULAR ALTERATIONS DURING HUMAN PREGNANCY: INDIAN RURAL PERSPECTIVE
Journal Title: International Journal of Basic and Applied Physiology - Year 2017, Vol 6, Issue 1
Abstract
BACKGROUND & OBJECTIVES: Pregnancy alters the cardiovascular physiology and may influence the maternal history of related disorders. The cardio-respiratory adaptations allow adequate fetal growth and development. Although, vital and required, scanty data for blood pressure indices for Indian rural population is found in literature. METHOD: After ethical approval ambience was created in OPD’s of Obstetrics and Gynecology department of Dhiraj General Hospital, Vadodara. The incidental and random selection led females in two groups, pregnant (N=300) and nonpregnant (N=100). Pregnant females were grouped as three different trimesters of pregnancy, 100 studied in each group. Blood pressure indices and pulse and its variables were assessed. OBSERVATIONS & RESULTS: Statistically significant (p <0.001) increase in pulse rate from nonpregnant (82.53) to pregnant (92.6) states rise of 12%, a difference of 10.07 beats/min. Gradual increase during gestation was recorded (ANOVA p<0.01). Blood pressure indices show insignificant trimesteric differences except for pulse pressure (ANOVA p<0.001). Pregnant females (N=300) showed minor but significant fall in SBP, DBP and MBP when compare to the non pregnant group, while PP showed significant rise in pregnant group (42.53±6.76 vs 44.34±8.42, p <0.05). CONCLUSION: Pregnancy is an adaptive phase in terms of cardiovascular parameters. The maternal blood pressure indices alterations are compensated via reflex increase in heart rate or vice versa. Thus, the pregnant women with respiratory diseases pose a special challenge. Other parameters are needed to be studied thoroughly in rural population as no literature is available.

A STUDY OF PEAK EXPIRATORY FLOW RATE IN HEALTHY ELDERLY PUNJABI FEMALES
Background: Age reduces the ventilatory capacity of lung/chest wall system and is thus expected to affect the PEFR. Peak expiratory flow rate (PEFR) is a relatively simple test to administer and is fairly repeatable. The...
