Dimensional Assessment of the Heart in Hypertrophic Cardiomyopathy Patients in Tertiary Care Hospitals

Abstract

Hypertrophic cardiomyopathy (HCM) is one of the most prevalent disorders responsible for sudden cardiac death. Presentation of the symptoms varies due to the degree of thickening, and functional ability of the cardiomyocytes. The aims of the current study were to assess the clinical features, and cardiac morphology. This was a descriptive study with some analytical components. Thirty-four adult HCM patients were included within a duration of four months by patient selection checklist. After informed written consent, relevant information was noted and analyzed. Frequency distribution of phenotypes were, 56% asymmetric septal hypertrophy, 29% concentric hypertrophy, and 15% apical hypertrophy. Breathlessness and chest discomfort were present in 56% and 62% patients respectively, and higher in asymmetric septal HCM. Palpitation was very frequent in concentric HCM (90%). ECG revealed left ventricular hypertrophy in 85% of patients, and 79% of them had ST change. The interventricular septal thickness was narrower in apical type (14.80mm). The posterior wall thickness was higher in concentric HCM (19.20mm). The left atrial size was smaller in Concentric type(34.60mm).
