ABSTRACT
Obesity has now become a global epidemic. It is one of the most significant contributors to a large number of health problems. A variety of adaptations/alterations in cardiac structure and function occur in the individual as adipose tissue accumulates in excessive amounts. Rate pressure product is a valuable marker of oxygen requirement of the heart. It is the product of heart rate and systolic blood pressure.
Aims: Our study aimed to compare the rate pressure product at rest between obese and non-obese women.
Settings and Design: It is a comparative, cross sectional type of study including 62 women (31obese and 31 non-obese respectively) aged between 31 to 40 years.
Methods and Material: Participant after being classified as obese or non-obese based on the body mass index was assessed for rate pressure product at rest. They were allowed to rest for 10 minutes in seated position. Brachial blood pressure and Heart rate was recorded in this position.
Statistical analysis: The rate pressure product values were analysed between obese and non-obese women using Mann Whitney test.
Results and conclusion: We found that the resting rate pressure product in obese women was significantly higher than non-obese women indicating there is increased myocardial oxygen consumption suggesting larger hemodynamic stress on the heart.
Key words: rate pressure product, body mass index, heart rate, systolic blood pressure, myocardial oxygen consumption, obesity.
