[Effects of altiazem PP and dilren on clinical symptoms, hemodynamic parameters and their chronologic structure in patients with stable angina].

Effects of altiazem PP-180 ("Berlin Chemie", Germany; "Menarini Group". Italy) and dilren-300 ("Sanofi", France) on clinical symptoms and circadian hemodynamic chronostructure were studied in 22 patients with coronary heart disease (CHD) with stable angina pectoris of functional class II-III. Tetrapolar chest rheography (TCR), echocardiography (Echo-CG), ECG, arterial pressure measurement (APM) by N. S. Korotkov were used for examination. TCR, ECG and APM were made 6 times a day: at 10.00, 14.00, 18.00, 22.00, 02.00 and 06.00. The drugs were given in a single daily dose at 08.00 for 10 days. The information was processed statistically and by F. Halberg's cluster analysis. The results showed that altiazem PP and dilren had an antianginal activity which is stronger in dilren administration. The drugs produced moderate hypotensive and vasodilating effects. Altiazem PP raised mean daily level of stroke and minute volumes and their indices. Dilren raised ejection fraction and reduced the double product. Dilren normalized chronostructure of hemodynamic circadian rhythms.
