    Abstract:
    Hypertensive emergencies, and to a certain extent their treatment, contribute to morbidity and mortality in elderly patients. We studied 22 hospitalized patients, aged 70-90 years, all of whom had moderate essential hypertensive. During acute hypertension, mean systolic and diastolic blood pressure rose to 230 +/- 24 and 120 +/- 22 mmHg, respectively. Symptoms of reduced tissue perfusion/oxygenation and/or organ failure occurred, forcing us to begin antihypertensive therapy. We administered 50 mg of the angiotensin converting enzyme (ACE) inhibitor captopril sublingually, and within 15 min, systolic blood pressure decreased by an average 60 +/- 16 mmHg and diastolic blood pressure by an average 25 +/- 14 mmHg. There was no significant change in the heart rate. In addition, we treated 22 comparable patients with 10 mg nifedipine sublingually and observed, in four cases, a greater fall in blood pressure (up to 90 mmHg) together with tachycardia. These results show the beneficial effects of captopril in the treatment of hypertensive emergencies in elderly patients. The absence of dangerous side effects indicates that ACE inhibitors can be used as first-choice drugs for the treatment of acute hypertensive crises, even in old age.
