Key result
Hypertension linked to ~18% lower FVC and reduced FEV1 versus nonhypertensive controls.
Why the study?
Studies that show the effect of hypertension on the lungs are limited.

Does hypertension affect pulmonary function in adults aged 30-64 years?
p-value: p=<0.05
Hypertension is associated with significantly reduced pulmonary function, predominantly a restrictive defect, highlighting the potential need for routine spirometry in this population.
Hypertension may link to reduced lung volumes in adults; leaves open causality and any role for routine spirometry pending prospective data.
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.

Birhan et al. (2018) conducted a cross-sectional in Hypertension (n=122). Hypertension vs. Nonhypertensive controls was evaluated on Pulmonary function values (FVC, FEV1, FEF25-75%, FEV1%) (p=<0.05). Hypertension was associated with significantly lower pulmonary function values, including FVC (3.52 vs 4.31 L) and FEV1 (2.97 vs 3.54 L), compared to nonhypertensive controls (p<0.05).
