Alteration of heart rate variability in patients with coronary artery disease

Coronary Artery Disease; Heart Rate Variability; Autonomic Nervous System INTRODUCTION Coronary artery disease (CAD) is a major cause of mortality and morbidity worldwide. [...]it is necessary to undertake population-based studies to identify risk factors for causation of CAD. There was no statistically significant difference between controls and cases in the anthropometric parameter. [...]the two groups were comparable.
