[Blood thyroid hormones in ischemic heart disease (a comparison with coronary angiographic data, severity of stenocardia and blood lipid level)].

The blood concentration of the thyroid hormones, thyroid stimulating hormone and lipids were estimated in 67 patients with ischemic heart disease (IHD), 12 patients with hypothyroidism (H) and 19 normal controls. H was diagnosed in 9% of the patients with IHD. There were similar changes of the blood lipid concentrations in the patients with IHD (without H) and the patients with H (without IHD): increased level of the total cholesterol, triglycerides, cholesterol of the low and very low density lipoproteins. The blood level of cholesterol of high density lipoproteins (C-HDL) was significally higher in the patients with H than in the patients with IHD. There was correlation of the level of thyroxine in the blood and clinical severity of angina pectoris among the euthyroid patients with IHD having the same degree of coronary atherosclerosis.
