| Annotation | Heart rate variability (HRV) is a measure of cardiac autonomic functioning. This study was to determine whether older primary care patients with a major depressive disorder (MDD) have lower HRV compared to non-depressed patients. A cross-sectional comparison of 136 older people with MDD and 136 non-depressed controls matched for age and gender were recruited in family practices in the Netherlands. Depression was determined according to the DSM-IV criteria using the Primary Care Evaluation of Mental Disorders (PRIME-MD). HRV was measured with an electrocardiogram (ECG) during a 5-minute supine rest. Multivariate analysis showed statistically significant decrease in HRV in MDD patients compared with controls. Other primary care patients with MDD have a reduced HRV. This may explain why depression is a risk factor for cardiovascular disease and mortality. (RH). |
