[Contemporary methods in the treatment of chronic pulmonary hypertension].
Pulmonary hypertension is involved in the development of various diseases and therefore it can be caused by several mechanisms from a simple pressure elevation in the pulmonary artery to the serious impairments of pulmonary vessels. The recently increased interest in the problems of pulmonary hypertension results namely from the new therapeutic means for the treatment of pulmonary arterial hypertension and chronic thrombembolic pulmonary hypertension. The algorism of pharmacotherapy results from the test of acute pulmonary vasodilation. Only the patients with positive test are indicated to the treatment with high doses of calcium channel blockers. Patients with negative test receive beside the chronic anticoagulation therapy also a specific pharmacotherapy (prostanoids, antagonists of endotheline receptors, phosphodiesterase 5 inhibitors) with not only vasodilatory but also with antiproliferative and antiaggregatory effects. When all possibilities of pharmacotherapy are exhausted, balloon atrial septostomy or lung transplantation should be considered. It has been shown recently that similar pharmacotheraeutic approaches as they are used in patients with pulmonary arterial hypertension are effective in some cases of other forms of chronic pulmonary hypertension. Method of choice in the treatment of chronic thromboembolic pulmonary hypertension is the pulmonary endarterectomy in patients with surgically curable thrombotic obstruction. In patients who are not suitable for surgical treatment it is necessary to try pharmacotherapy (prostacycline, bosentan, sildenafil) or lung transplantation. Complicated diagnosis and therapy of pulmonary hypertension requires concentrating the treatment into specialized centres with multidisciplinary background and sufficient experience. In the Czech Republic, the care of patients with pulmonary hypertension is concentrated into the Cardio Center of the 2nd Medical Department of the 1st Faculty of Medicine and General Teaching Hospital in Prague and into the Cardio Center of the Institute of Clinical and Experimental Medicine in Prague. Complex care to patients with chronic thromboembolic pulmonary hypertension is given at the Cardio Center of the General Teaching Hospital in Prague, where since September 2004, 99 patients were surgically treated with results comparable to the best similar departments abroad.
