[Bronchial asthma and pulmonogenic arterial hypertension]

The arterial hypertensive syndrome was studied in 216 patients with bronchial asthma, 17 to 67 years of age (mean age 43.6 years), duration of the disease form 1 up to 19 years. To all patients bicycle ergometry with a permanent load of 60 W for 5 min. was applied. The results showed that in 145 patients (67.12%) arterial hypertensive syndrome was present during the bronchopulmonary obstruction. In 105 of these patients (48.6%) the hypertension was pulmonogenic and in 40 patients (18.51%) the arterial hypertension was an accompanying disease. In 62 patients (28.70%) the pulmonogenic hypertension was of a labile type and in 43 patients (19.90%) it was stable. A marked correlation was found between the values of the increased arterial pressure and the indices of bronchopulmonary obstruction--forced expiratory volume/min, Tiffneau's index, maximal expiratory flow, mean maximal expiratory flow. Hypotensive treatment is recommended in patients with stable pulmonogenic hypertension and with accompanying arterial hypertension only.
