[External respiratory function in stages I and II arterial hypertension].
AIM: To examine external respiratory function (ERF) and pulmonary circulatory hemodynamics in patients with Stages I and II arterial hypertension (AH). MATERIALS AND METHODS: 105 patients with AH were examined. In 43 of them, spirography and echocardiography were performed with pulmonary pressure and determined during elevated blood pressure (BP) and antihypertensive therapy. RESULTS: ERF disorders that recovered with BP lowering were detected in 62.8% of patients with AH. There were also signs of elevated pulmonary pressure. CONCLUSION: In patients with HF, pulmonary hemodynamic disorders, changes in ERF, and the degree of AH are closely interrelated.
