[The characteristics of the lung microcirculation and external respiratory function in bronchial asthma patients with systemic arterial hypertension].

In 43 patients suffering from bronchial asthma, the data on patients with normal and high systemic arterial pressure were correlated on the basis of studying external respiratory function and pulmonary circulation. The differences are demonstrated as regards the intensity of obstruction, the ratio of changes in lung perfusion to bronchial patency, the response to berotec and the calcium antagonist perdipine.
