Abstract : Cardiac Autonomic Neuropathy (CAN) is a chronic complication of diabetes mellitus and is associated with increased morbidity and mortality. Though very common, it is frequently under diagnosed. So CAN should be identified early to prevent its debilitating complications. To estimate the prevalence of Cardiac autonomic neuropathy (CAN) in type-II Diabetes Mellitus participants in a tertiary care hospital. This was a cross-sectional study undertaken in a tertiary care hospital from December 2019 to November 2020. A total of 273 patients with type-II diabetes mellitus of either gender were selected for the study. A questionnaire with socio demographic details, anthropometric measurements, laboratory parameters & ewings noninvasive cardiac autonomic neuropathy reflex tests for detecting CAN were administered to each participant. Based on ewings and clarkes criteria, Patients with CAN were categorized in to early, definite and severe type of CAN. Data were analysed using SPSS 16. In this study the prevalence of CAN among type-II diabetic patients was found to be 34% (93/273). Among the patients with CAN, Definite CAN was found among majority of patients 55% (51/93) followed by early 39% (36/93) and advance (6%) (6/93). E-I ratio was abnormal 58/93(62%), borderline 22/93(24%) and normal 13/93 (14%), 30:15 ratios were abnormal 46/93 (50%) than borderline 26/93 (28%) and normal 21/93 (22%) and Valsalva ratio was borderline 55/93 (58%) than abnormal 27/93 (30%) and normal 11/93 (12%) among the type-II diabetes with CAN positive. The average means of age, BMI, duration of diabetes & HbA1c were significantly high in CAN Positive participants compared to Non CAN participants. In our study Prevalence of CAN among type-II diabetes was 34 %. As prevalence is high, it is recommended that type-II diabetes patients should be examined frequently for CAN by using these simple bedside tests.
