Vital cardiovascular parameters, Reference equations, Normal population.Abstract
Introduction: Normal subjects are healthy peoples who have no cardiovascular symptoms. These people have usually normal values of cardiovascular parameters. Since reference values are influenced by a variety of factors including age, gender, stature, genetic and geographical region of living, though the reference values of one population should be used for that population. The aim of this study was to identify the physiological values of cardiovascular system in Iran adult population and obtain the reference equations for these parameters.
Methods and Materials: Sample subjects were selected randomly through different cities in several regions of the country. Healthy individuals were identified after medical examination Cardiac parameters including heart rate, systolic and diastolic blood pressure, and pulse pressure were measured using standard methods and devices by expert researchers.
Results: The results obtained were calcified for different ages of men and women. Mean values for each parameters was calculated and then reference equations were derived for each parameters as below.
Heart rate = 101.791 – 0.086 (age) – 0.132 (height)
Diastolic pressure = 59.068 + 0.129 (age) + 2.653 (sex) + 0.15 (weight)
Systolic pressure = 82.078 + 0.454 (age) + 0.64 (height) + 4.293 (sex) +0/63 (weight)
Pulse pressure = 18.712 + 0.235 (age) + 0.097 (height) + 1.451 (sex)
Conclusion: Using these equations, one can predict cardiac parameters for anyone with his/her features (age, sex, height and weight).
