Left ventricular systolic indices in hyperthyroidism

Abstract

This study was designed to determine the correlations between the serum levels of FT3 (free triiodothyronine) and FT4I (free thyroxine index) and left ventricular systolic indices in hyperthyroid patients. Thirty patients, 25 females and 5 males were studied. The age range was 16 to 35 years with a mean of 26.87 years. Highly significant correlations were found between both FT3 and FT4I with QS2 (total electromechanical systole), LVETI (left ventricular ejection time index), and velocity of contraction, P<o.001. There were also significant correlations between PEPI (pre ejection period index) and EF (ejection fraction) with both the hormones, P<0.01 The results suggest that the left ventricular systolic indices, while very useful in the follow up of the patients, can also be used as an adjunct in the diagnosis of hyperthyroidism.
