Treatment of essential hypertension with captopril in patients with chronic obstructive pulmonary disease.

The effects of captopril have been studied in 10 patients suffering from chronic obstructive pulmonary disease (COPD) with moderate essential hypertension. Captopril was given as monotherapy (75-100 mg/day) over a period of 60 days. The following effects of captopril were seen in these patients: a significant reduction of systolic blood pressure (P less than 0.01) and of diastolic blood pressure (P less than 0.001), both in the supine and in the standing position; a significant increase of the vital capacity (P less than 0.05); no significant change in other various respiratory function tests or of heart rate, and no side effects, including bronchospasm in the patients sensitive to bronchodilator drugs. The present data suggest that in COPD patients with essential hypertension, captopril is an effective hypotensive agent and has no adverse effects in pulmonary function.

Left ventricular mass and function before and after antihypertensive treatment.

We have studied the effect of blood pressure control upon left ventricular mass and function. Twenty hypertensive patients without clinical or electrocardiographic signs of cardiac involvement were given sequentially: placebo for two weeks; captopril (250 mg/day) for eight weeks; and captopril (125 mg/day), alone or combined with chlorthalidone (25 mg/day), for eight weeks. M-mode echocardiography was performed at the end of placebo period, after eight and after 16 weeks active treatment. Blood pressure was significantly reduced (p less than 0.01) by therapy, the maximum decrease being observed at the end of the study. Similarly, interventricular septal thickness, posterior wall thickness and left ventricular mass index showed a significant reduction (P less than 0.01 at the eighth and P less than 0.001 at the 16th week), while no changes were detected in left ventricular function. Furthermore, both wall stress index at end-diastole and end-systolic stress were significantly lowered by treatment (at the 16th week P less than 0.01 and P less than 0.001, respectively). Baseline systolic blood pressure was inversely correlated with the ratio of the left ventricular radius to posterior wall thickness (r = -0.97, P less than 0.001) but no relation was found between post-treatment fall in either systolic or diastolic blood pressure and left ventricular mass index. After treatment more patients showed normal left ventricular wall thickness in relation to systolic blood pressure. We conclude that in uncomplicated hypertensive patients captopril, either alone or combined with chlorthalidone, can reverse left ventricular hypertrophy by decreasing both septal and posterior wall thickness.(ABSTRACT TRUNCATED AT 250 WORDS)

[The role of renin after betablocking diuretic and vasodilator treatment in essential hypertension (author's transl)].

Ten patients affected by essential moderate or severe hypertension were given five sequential treatments, each for three weeks: 1) placebo, 2) chlorthalidone (Cl) 100 mg daily, 3) Cl 50 mg + oxprenolol slow release (Ox) 160 mg daily, 4) Ox 160 mg and 5) Ox 320 mg daily. Four subjects poor responders (DPB greater than or equal to 110 mmHg) received a later administration of Ox 160 + Cl 50 + hydrallazine (Hydr) 25-100 mg daily. Both groups of patients showed the greatest antihypertensive action with Ox 160 + Cl 50 mg daily. Oxprenolol induced a similar hypotensive effectiveness at 160, as well as 320 mg/day. Relationship between plasma renin activity (PRA) values and antihypertensive response to each treatment takes the following conclusions: 1) Basal PRA levels cannot be a guide for preferential choice of diuretic or betablocking therapy. 2) It is likely that renin activated by Cl and Hydr partially blunts their hypotensive activity. On the contrary, essential hypertension with normal or low PRA does not seem depending on angiogensinogenic factors. 3) Oxprenolol remarkably inhibits the overreninism induced by chlorthalidone and hydrallazine, in such way increasing their antihypertensive action. 4) In the management of essential moderate or severe hypertension is preferable to employ a mild dosage of betablockers and diuretics, rather than use higher doses of a single agent.
