title: [Results of a 5-year study with captopril in patients with severe therapy-resistant hypertension].
abstract: The angiotensin converting enzyme (ACE) inhibitor captopril proved to be an effective antihypertensive drug during a 5-year follow-up study of patients with severe hypertension who had been resistant to a triple-drug regimen. Of the 42 patients, 41 had to be treated additionally with diuretics. Because of hypokalemia, potassium supplements were necessary in 26 patients, despite the use of "potassium-saving" diuretics in 12 patients. Blood pressure was controlled sufficiently in 3/4 of the patients during the 5 years. Patients with a large elevation in plasma renin activity showed the best response to the treatment. Six patients died during the 5 years. Therapy had to be stopped in 11 patients because of complications. The following complications and adverse effects were observed: cerebral ischemia (n = 10), vertigo and orthostasis (10), exanthema (9), hypogeusia (7), circulatory failure (7), myocardial infarction (6), and scintigraphically demonstrable decrease of renal perfusion (5). One patient with bilateral renal artery stenosis suffered from acute renal failure, which was reversible after withdrawal of captopril. Significant changes of red and white blood cell counts, transaminases, lipids, urine protein excretion, and heart rate were not observed.
