Abstract
BACKGROUND: Hypertension imposes stresses on many organs like heart and kidney. However, studies that show the effect of hypertension on the lungs are limited. OBJECTIVE: To assess pulmonary function status of hypertensive patients aged 30-64 years at Zewditu Memorial Hospital, 2017. METHODS: Hospital based comparative cross-sectional study was conducted on 61 hypertensive patients (cases) and 61 nonhypertensive clients (controls) aged 30-64 years. Computerized spirometry was done in all cases and controls which were selected by systematic sampling technique. The study was conducted from January 20, 2017, to May 25, 2017. Result. The values of FVC, FEV1, and FEF25-75% were 3.52±1.02 liters, 2.97±0.89 liters, and 3.34±1.3 liters/second in hypertensive patients and 4.31±0.82 liters, 3.54±0.7 liters, and 3.94±1.09 liters/second in controls, respectively. These values were significantly lower (p<0.05) in hypertensive patients compared to controls. Restrictive pulmonary defect was dominant in hypertensive patients. FEV1% which was 85%±7% in hypertensive patients and 82%±5% in controls was significantly higher (p<0.05) in hypertensive patients compared to controls. CONCLUSION: Hypertensive patients exhibit lower pulmonary function values. Routine check-up of the pulmonary function status of such patients should be done to prevent undesired outcomes.
