A study of prevalence of cardiomyopathy in diabetes mellitus as evidenced by electrocardiography and 2-D echo
Background: Diabetic cardiomyopathy is characterized by diastolic dysfunction, which is rarely clinically apparent unless associated with hypertension and/or with myocardial ischemia. The aim of the study was to determine the prevalence of cardiomyopathy in diabetes mellitus.
Methods: This study was carried out on patients coming as out patients (100) to Dr. D.Y.Patil Hospital & Research Centre, Nerul Navi Mumbai from June 2006 to December 2008.
Results: In this study maximum number of diabetics are between the age group of 41-50. Males (65) are more common than female (35). Main complaints of the patients coming to OPD was chest pain (59%), followed by giddiness (48%), breathlessness (47%), sweating (33%). ECG changes does not have any correlation with duration of DM. ECG changes related to cardiomyopathy were present in 38 out of 65 males and 25 out of 35 females i.e. total number of 63 subjects had ECG changes related to diabetic cardiomyopathy. 28 males and 16 females had diastolic dysfunction in 2 D Echo. Maximum numbers of patients with diastolic dysfunction were between the age group of 51-60 years in male and females i.e. 11 and 08 respectively. 46 patients had mild systolic dysfunction. 40 patients had normal systolic function but 13 patients had moderate systolic dysfunction while only 01 patient had severe systolic dysfunction.
Conclusions: Prevalence of cardiomyopathy in diabetes in present study as evidenced by ECG is 63% and by 2 D Echo it is 62%. Patient with DM of 5 years of duration, should be properly screened & put on proper inotropic drugs to prevent the worsening of diabetic cardiomyopathy.
