Investigating the Physiological Changes in the Cardiovascular System across Ages 25 to 75 Years

The aim of the present study was to investigate the physiological changes that occur in the cardiovascular system with advancing age. 50 males and females, in the age group of 25-75 years, participated in the study. Clinical evaluation included assessment of heart rate, blood pressure, complete lipid profile and blood glucose in addition to details of medical history and personal habits, with particular regard to smoking habits and alcohol intake. Results showed that VO2max, sub-maximal heart rate and maximal heart rate were significantly negatively correlated to age (r = -0.523, -0.745 and -0.824 respectively), whereas blood pressure was significantly positively correlated to age (r =0.383). The study concluded that aging has a depreciatory effect on the cardiovascular functions causing a decline in the various physiological parameters of the cardiovascular system across ages 25 to 75 years, with an increased tendency of occurrence after 45 years of age.
