Abstract :

AIMS AND OBJECTIVES 1)To study the clinical features of diabetic autonomic neuropathy with special reference to cardiac autonomic neuropathy.2) To study the prevalence of cardiac autonomic neuropathy in type 2 Diabetes Mellitus. 3) To find correlation between Cardiac Autonomic Neuropathy and Retinopathy in type 2 Diabetes Mellitus MATERIAL AND METHODSThe study was carried out in the outpatient and inpatient services of tertiary care hospital. A total of 50 patients were studied. Inclusion criteria were Patients with Type–2 Diabetes Mellitus .Exclusion criteria were Presence of valvular heart disease, heart failure, cardiac arrhythmias, congenital heart disease.2 Type 1 Diabetes Mellitus.3 Acute complications of DM like Diabetic Ketoacidosis, hypoglycemia. TESTS for CAN :1) valsalva test (heart rate variation in valsalva maneuver :2). heart rate response to deep eathing 3) heart rate response to standing 4) drop in systolic blood pressure on standing. Retinopathy was assessed by fundus examination carried out for all patients with the help of ophthalmologist Nephropathy was assessed by estimating proteinuria with the help of commercially available dipsticks. It was graded as 1+ to 3+. RESULTS– 1.) The age group commonly involved was 51–60 years.14/29(48.27%) 2.) There was equal sex distribution.Males = 15/29 (51.72%), Females = 14/29 (48.27%) . 3)Dizziness on standing was the most common symptom. (24%) 4).Heart rate variation on deep eathing was the most abnormal test to be detected in 19(38%) patients. 5). Cardiac autonomic neuropathy was detected in 29 patients (58%) 6). Age, gender and BMI had no significant correlation with the occurrence of CAN ,7) Duration of diabetes had positive correlation with presence of cardiac autonomic neuropathy. (P–value
