    Abstract:
    Alterations in cardiovascular hemodynamics are found in patients with hypofunction of the thyroid. Frank hypothyroidism favours the development of coronary heart disease. Platelets are thought to be important in atherosclerotic lesions initiation and progression. We studied platelet sensitivity to several agonists and to a physiological antagonist, prostacyclin, and thromboxane production in patients with hyperthyroidism and hypothyroidism. No statistically significant differences were found between platelets activities in patients and control subjects. We conclude that increased platelet function is not a direct indicator of susceptibility to cardiovascular diseases in patients with hypothyroidism whereas the hyperdynamic state, cardinal manifestation of thyrotoxicosis, is not associated with platelet activation.
