A STUDY ON PREVALENCE OF CARDIOVASCULAR AUTONOMIC NEUROPATHY IN TYPE 2 DIABETES AND UTILITY OF CORRECTED QT INTERVAL FOR ITS DIAGNOSIS

Abstract :

Background: cardiovascular autonomic neuropathy (CAN) in diabetes is a common but often under diagnosed & underestimated. CAN is associated with increased mortality , silent myocardial infarction ,left ventricular dysfunction, chronic kidney disease. Early recognition of CAN will help to delay or arrest its progression Methods: A cross–sectional study to evaluate the Prevalence of CAN in Type 2 diabetes & correlate it with duration of Diabetes and to investigate the relationship between cardiac autonomic dysfunction & QTc Results: Prevalence of definite CAN was 8%, 24% and 58% in group A, B and C of study population respectively and also prevalence increases with increase in duration of diabetes. P value <0.001 significant Conclusions: A significant correlation is present between CAN & QTc prolongation. QTc interval in the ECG can be used to diagnose CAN with a reasonable sensitivity & specificity
