Study on Causes and Investigative Findings in Cardiomyopathy Patients in A Tertiary Care Hospital in Eastern India

Abstract

Introduction: For a long time, confusion about terminology and definitions has kept the public and medical organisations from fully understanding the wide range of conditions known as cardiomyopathies. In an effort to bring more clarity to these complex illnesses, numerous classification systems have been devised to help with their characterization and to help establish connections or distinctions between them.

Aims: To evaluate 100 cases of dilated cardiomyopathy and identify various etiological factors, the clinical profile of patients with dilated cardiomyopathy and to study the electrocardiographic and echocardiographic profile of these patients

Materials and methods: It was a Cross sectional study this study was conducted from May 2022 to December 2023 at Nil Ratan Sircar Medical College and Hospital

Result: Our study indicated that ischemic dilated cardiomyopathy, which accounts for 47% of all cardiomyopathies, is followed by alcoholic cardiomyopathy at 15% and diabetic cardiomyopathy at 11%. Twelve percent of patients had idiopathic DCM, and nine percent had peripartum cardiomyopathy.Three cases of valvular cardiomyopathy (mitral regurgitation and aortic regurgitation), two cases of HIV cardiomyopathy, and one case of post viral myocarditis made up the six cases (or 6% of the total) representing the miscellaneous category.

Conclusion: Sinus tachycardia, atrial fibrillation, and left bundle branch block are the most prevalent abnormalities found in electrocardiograms. Electrocardiogram (ECHO) results showed generalised hypokinesia and reduced EF. Mitral regurgitation and pericardial effusion were conditions experienced by a significant number of persons. Patients with NYHA class 1V were more common.
