[Interaction of calcium drug and vitamin D3 with some medicines used in coronary heart disease therapy].

130 young and middle age patients of both sexes with chronic form of coronary heart disease: functional class II-III stable exertional angina pectoris including functional class I-III chronic cardiac insufficiency were studied. In protocol 1 cured 70 patients (48 (68.6%) males and 22 (31.4%) females) 32-59 years of age (medium age was 48.4 +/- 3.25 years) with coronary heart disease. In protocol 2 (with prescription of calcium-D3) cured 60 patients (40 (66.7%) males and 20 (33.3%) females) 34-58 years of age (medium age was 47.8 +/- 3.12 years) with coronary heart disease. The groups were comparable on key parameters of disease. All patients had alimentary calcium deficit and (or) risk factors of osteoporosis, instrumental signs (X-ray filming and densitometry) of initial or evident osteoporosis. Correction of alimentary calcium deficit was realized by prescription of 1-3 tablets of calcium- Ds in different food intakes. Positive dynamics in decrease of functional class of angina pectoris and nitroglycerin requirement in both groups was noticed. Negative influence of calcium- D3 on studied indices of coronary heart disease severity was absent. The thirst and dry mouth in patients, who took furosemide, in group 1 were noticed against the background of body weight decrease (p < 0.05) and increase of diuresis. Decrease of the therapy antiarrhythmic action (p < 0.05) in patients, who took hydrochlorothiazide, was noticed too. It leaded to needs of furosemide and hydrochlorothiatide dose correction in protocol 1. In whole use of calcium- D3 together with anti-ischemic drugs in patients with chronic forms of coronary heart disease did not impair clinical course of angina pectoris and did not decrease efficiency of coronary heart disease therapy.
