Abstract

Background: Hyperthyroidism is defined as excess concentration of thyroid hormones
in the body due to either increased synthesis of the thyroid hormone, increased release
of preformed thyroid hormones, or from endogenous or exogenous extrathyroidal
sources. The present study was conducted to assess cardiovascular manifestations of
hyperthyroid disorder patients.
Materials & Methods: 104 patients of hyperthyroidism of both gendersunderwent
clinical evaluation, basic laboratory tests like CBC, RFT, LFT and ECG and 2D ECHO
were performed in these patients to evaluate the presence of any cardiac manifestations.
Results: There were 34 males and 70 females. Age group upto 40 years had 20, 41-60
years had 34 and >61 years had 50 patients. Common symptoms were pallor in 90,
edema in 86, moist skin in 74 and eye signs in 53. Cardiovascular symptoms recorded
were chest pain in 82, palpitations in 95 and breathlessness in 60. Among 104 patients,
ECG changes were seen in 42 patients. Out of this, sinus tachycardia was seen in 65%,
AF in 10%, ST T changes in 6%, RVH in 7%, LVH in 11% and RBBB in 5%. The
difference was significant (P< 0.05).
Conclusion: Cardiovascular manifestations are quite common in hyperthyroid patients.
