Efficacy and pharmacokinetics of gallopamil in patients with coronary artery disease.

We prospectively studied 10 patients with stable exertional ischaemia, selected from a larger group of patients referred for suspected coronary artery disease or to detect residual ischaemia after myocardial infarction, to evaluate pharmacokinetic changes during chronic treatment with gallopamil and its correlation with clinical efficacy in patients with coronary artery disease. Our study consisted of a 1-week run-in single-blind placebo treatment and a 4-week single-blind gallopamil treatment. At the end of the run-in period patients underwent two different exercise tests, the first 2 hours and the second 7 hours after placebo administration.

Age-response effectiveness of gallopamil for the treatment of myocardial exertional ischemia. A medium-term randomized cross-over double-blind placebo-controlled trial.

We evaluated the efficacy and safety of gallopamil 150 mg daily in middle-aged and elderly patients with stable exertional ischemia, using a medium-term randomized double-blind cross-over placebo-controlled trial. Twenty middle-aged patients (52.8 +/- 6 years; range 38-61 years) and 14 elderly patients (67.

Age-related changes of antianginal effects of verapamil in patients with stable effort angina. A medium term randomized double-blind placebo controlled trial.

Our study evaluated the effects of verapamil in elderly patients with stable effort angina using a medium-term double-blind placebo-controlled protocol. Thirty-nine consecutive patients, 23 middle-age patients (50 +/- 6 years; range 38-60 years) and 16 elderly patients (66 +/- 2 years; range 65-70 years) with exertional angina were chosen. After a run-in period, both groups received treatment with either placebo or verapamil--360 mg daily--for 4 weeks.

Acute effects of nifedipine, diltiazem and their combination in patients with chronic stable angina: a double-blind, randomized, cross-over, placebo-controlled study.

We evaluated the acute therapeutic effects of the oral administration of nifedipine (10 mg) and diltiazem (120 mg) alone and in combination in 16 patients with effort angina. The 16 patients (13 men and three women; mean age 59 +/- 7 years) performed a symptom-limited bicycle exercise stress test 3 h after placebo or active substance administration. Maximal work load, exercise duration and time to 1 mm ST segment depression were significantly increased and ST depression at peak exercise was significantly decreased by the combination of drugs.

[Diagnostic value of microalbuminuria and the calcium/creatinine ratio in the early detection of preeclampsia].

We have evaluated the biochemical and clinical parameters for early detection of their alterations in pregnant women with late preeclampsia. Eighty nine patients between 24 and 32 gestation weeks were studied. Fifteen of them (18%) developed arterial hypertension (mean 141.

Effect of beta-adrenoceptor blockade on dipyridamole-induced myocardial asynergies in coronary artery disease.

Twenty-one patients with angiographic evidence of significant coronary artery disease, and positive dipyridamole echocardiographic test results at basal condition and after 7 days of placebo treatment were prospectively studied to see whether beta blockade modifies the effects of dipyridamole echocardiographic testing on regional myocardial contractility. Patients were randomized to propranolol (120 mg/day) or placebo treatment in 3 divided doses for 7 days, after which each patient crossed over to the alternate regimen. Dipyridamole-echocardiographic testing was repeated at the end of each treatment.

[Efficacy of diltiazem in elderly patients with stable effort angina].

The antianginal effects of 360 mg/day of diltiazem were evaluated, using intrapatient comparisons, in a double/blind, randomized, placebo/controlled trial in 24 young patients (50 +/- 7 years) and in 16 elderly patients (67 +/- 3 years) with stable effort angina. All patients had angiographic documentation of significant coronary artery disease. An open-labelled, randomized, crossover design was employed.
