Objective
Recent evidences have emphasized an association between autonomic dysfunction and existence of metabolic syndrome (MetS).The present study aimed to assess changes in resting and maximum heart rates as main indicators of cardiac autonomic function in MetS patients and also determine its value for discriminating MetS from no-MetS conditions.
Methods
A total of 468 participate enrolled in this cross-sectional study. The updated ATP-III definition of the metabolic syndrome was met and both resting and maximum heart rates were attained during the exercise test by equipment connected to the treadmill according to the Bruce protocol. Fasting blood sugar and lipids determined by enzymatic methods. A receiver operating characteristic (ROC) curve was used to identify the best cutoff point by which to maximize the sensitivity and specificity of discriminating MetS from no-MetS State.
