Background: In this study 100 cases of thyroid dysfunction were studied for the cardiovascular manifestations. Out of these, 60 cases were of hypothyroidism and 40 cases were of hyperthyroidism.
There was no age bar for inclusion in the study. All of these cases were selected from those attending the Endocrinology OPD in IMCHRC hospital, Indore.
Result: Low pulse pressure is the commonest cardiovascular finding in hypothyroidism (68.33%) followed by diastolic hypertension (55%), soft heart murmur (31.66%), sinus bradycardia (30%) and pericardial effusion (20%) Pulse pressure >40 mm of Hg is the commonest finding in hyperthyroidism. Almost all patients of hyperthyroidism have sinus tachycardia.
Conclusion: Study of cardiac signs and symptoms in patient with hyperthyroidism revealed 87.5% prevalence of pulse pressure > 40 mm hg, 85% prevalence of loud heart sound, 82.5% cases of sinus tachycardia, 52.5% cases of hyperdynamic precordium, 47.5% cases of ejection systolic murmur, 42.5% cases of prolonged Qt interval, 25% cases of precordial thrill, 47.5% patients with systolic BP>160 mm Hg, 20 5 cases with mid systolic click, 27.5% patients with LVH , 15% cases with ST-T changes, 5% cases with S3 and 10% patients with atrial fibrillation.
