[Dynamics of the serum lipid indices in thyrotoxicosis].

Total cholesterol, HDL-cholesterol, triglycerides, NEFA and phospholipids were studied in the sera, before the treatment, in 45 patients (40 females and 5 males) aged from 14 to 73 with various forms of hyperthyroidism. In 16 of them the studies were repeated about one month after the initiation of the thyreostatic treatment, when the hyperthyroid symptomatics has obviously been controlled. The results obtained about the separate serum lipid indices of the patients were discussed, compared with the data of the control group (n = 14), as well as the role of the low serum HDL-cholesterol and increased triglycerides in the genesis of thyreotoxic cardiomyopathy.
