[Hypothyroidism and the heart].
The cardiovascular system is sensitive to the action of thyroid hormones, and thyroid dysfunction causes a wide spectrum of cardiovascular changes. The effect of overt hypothyroidism on the cardiovascular system has long been recognised. Nowadays, the clinical presentation of cardiovascular symptoms related to hypothyroidism is only rarely observed due to early diagnosis of hypothyroidism by easily available thyroid-stimulating hormone assays. Overt hypothyroidism causes changes in such parameters of cardiovascular function as heart rate, left ventricular systolic and diastolic function, blood, arterial pressure and systemic vascular resistance. During the last years, there has been increasing evidence that subclinical hypothyroidism may also impair the cardiovascular system. This review discusses the effect of hypothyroidism on the cardiovascular system.
