Abstract— Association of Hypertension and Pulmonary Functions. Association between cardiac dysfunction and abnormal pulmonary function has remained controversial since long. The objective of this study is to find out the association of hypertension and its severity on pulmonary functions. Study was conducted on 30 hypertensive (study group) and 30 non hypertensive (control group) subjects identified from Medical OPD of SMS Hospital, Jaipur. Pulmonary functions were assessed of both hypertensive (study group) and non hypertensive (control group) subjects by Medspiror). Among pulmonary function tests, difference in means of FVC, FEV1 PEFR, FEF25-75%, MVV and FVC/ FEV1 were found less with significant difference in cases group with predominantly restrictive type of effects are observed. Female’s shows lower values than male hypertensive subjects. Furthermore, FVC, FEV1, PEFR, FEF25-75%, MVV, FVC/ FEV1 were not found to be associated with severity of illness. An inverse relation is found between hypertension and pulmonary functions predominantly restrictive type of pattern. While non significant effects are observed with severity of illness.
