Abstract :
OBJECTIVE: To evaluate the cardiac manifestation in patients with hyperthyroidism.
PATIENTS AND METHODS: This descriptive study was conducted from January 2015 to June 2015 on subjects
with clinical manifestation of hyperthyroidism. The inclusion criteria of the study were patients, of ≥12 years of age,
either gender with hyperthyroidism. The subjects were further evaluated for cardiac manifestations by advising Xray
chest, ECG and echocardiography. The frequency / percentages (%) and means ±SD computed for study
variables.
RESULTS: Total fifty patients of hyperthyroidism were identified to have cardiac manifestations and were
evaluated and enrolled in the study. The mean ±SD for whole population was 48.87±5.86 while the mean free T3, T4
and TSH was 720.87±10.96 pg/d, 4.98±1.84 ng/dl and 0.23±1.20. The male population was predominant (60%)
while the common symptoms observed were palpitation, dyspnoea, chest pain and tachycardia. The ECG,
echocardiograph and chest X-ray was abnormal in 41(82%), 23(46%) and 18(36%). The ECG findings were sinus
tachycardia, LVH and atrial fibrillation while the echocardiographic findings were chamber enlargement, MR and
AR where as X-ray shown cardiomegaly.
CONCLUSION: The patients of hyperthyroidisms should be carefully evaluated as early detection and appropriate
treatment is a best strategy to reduce cardiovascular complications associated with hyperthyroidism.
