[Thyroid hormone content of the blood plasma and functional state of the myocardium in patients with chronic forms of ischemic heart disease].
Sixty-seven patients with angiographically-confirmed coronary heart disease (CHD) were investigated. Three patterns of thyroid hormone (T3 and T4) response to exercise were identified: rising, falling and unchanged levels. Coronary patients with rising T3 levels in response to exercise typically showed smaller left-ventricular ejection values as compared to those patients whose T3 levels declined. Coronary patients with low baseline T3 tended to have elevated left-ventricular end diastolic pressure after exercise. The demonstrated changes in plasma thyroid hormone levels are related to the severity of coronary disease and can be "protective" or, on the contrary, aggravating. Because of smaller biologic activity, T4 does not basically affect clinical manifestations of CHD.
