CORRELATION OF BLOOD PRESSURE WITH PULMONARY FUNCTION OF ELDERLY PEOPLE WITH HYPERTENSION IN EAST PURWOKERTO SUB-DISTRICT

Abstract

Background: Hypertension is included in the list of non-communicable diseases with the first highest prevalence in the elderly. Not only does it affect the increased risk of cardiovascular disease, but hypertension also influences reducing lung performance in sufferers. Researchers are interested in seeing the correlation between blood pressure and lung function in elderly people with hypertension.

Methods: This research is a cross-sectional study. The study subjects were 31 people, collected using the purposive sampling method. The criteria for research subjects were uncontrolled hypertension patients aged ≥ 45 years, who did not have respiratory system disorders and were willing to become research subjects by signing an Informed Consent. Blood pressure examination was performed by auscultation method using a stethoscope and mercury sphygmomanometer. Pulmonary function was measured using a spirometer to see the value of FVC and FEV 1. Data analysis used the Pearson correlation test with Spearman's alternative test. Significance level at p<0.05.

Results: A total of 19 people (61.3%) have normal lung function which can be seen in the FVC and FEV1 values. The results of the correlation analysis test of blood pressure with lung function parameters in elderly patients with hypertension showed no correlation between blood pressure and lung function as indicated by p>0.05. However, there was a negative correlation between blood pressure and lung function FVC (r = -0.317 for systolic blood pressure; r = -0.323 for diastolic blood pressure) and FEV1 (r = -0.273 for systolic blood pressure; r = -0.242 for diastolic blood pressure). The higher the blood pressure, both systolic and diastolic, the lower the lung function of both FVC and FEV1.

Conclusion: There is no correlation between blood pressure and lung function of elderly people with hypertension in East Purwokerto District. There is a tendency of negative correlation between blood pressure and lung function. The higher the blood pressure, the lower the lung function.
