Introduction: Angina pectoris is the usual clinical manifestation of transient myocardial ischemia, which, in turn, is a condition of myocardial suffering occurring when coronary blood flow is insufficient to meet oxygen requirements by myocardial cells necessary to carry out their contractile function. It is suggested that physical activity is most effective at reducing or preventing heart failure. However, the association of physical activity level (PA) with angina symptoms and blood pressure (brachial systolic, BS; brachial diastolic, BD; ankle systolic, AS and ankle diastolic, AD) in middle-aged and old patients with heart failure is not well established.
Methodology: Two hundred and ninety nine patients with heart failure were divided in two age groups of 45-59 years old (middle-aged, n = 175) and 77-60 years old (old, n = 124). The angina symptoms (Rose angina questionnaire), blood pressures and physical activity level were assessed by the participants. Partial and Pearson correlation coefficient were used for analyses of data.
Results: In middle-aged group, the PA had a significant negative correlation with angina symptoms (P = 0.004, R = - 0.221) independent of age, body weight, body mass index (BMI) and abdominal, but not for old group. Against, there was a positive and significant correlation between the angina symptoms and age in the old group (P = 0.020, R = 0.212); however, this relationship was not significant for the middle-aged group. There were no significant relations between the PA and age with blood pressures for both groups (all, P ˃ 0.05). However, there were significant positive relations between the AS and AD with body weight, BMI and abdominal in middle-aged group (all, P ≥ 0.014, R ≥ 0.185) but not for old group. A significant positive correlation was noted between the BS with body weight (P = 0.031, R = 0.193); and BMI (P = 0.024, R = 0.203) in old group only.
Discussion: According to the findings, it seems that the level of physical activity in the middle-aged patients is an effective factor for decreasing the angina symptoms, compared to the old group. Also, it is suggested that the blood pressure is more affected by body weight than the level of physical activity. In addition, it should be noted that brachial systolic blood pressure in old patients for monitoring, while ankle systolic and diastolic blood pressure in middle-aged patients.
