Health disparities in chronic back pain and associated mortality seen in ischemic cardiac disease: a commentary.

Prescription opioid use for nonmalignant chronic pain has grown in the US over the last decade. Those with chronic back pain have a higher risk of mortality from ischemic heart disease than those without. Studies have demonstrated a higher prevalence of cardiac disease in adults who report chronic pain. In addition, there is research that supports some association with pain sites and cardiovascular morbidity. Studies have also shown a high-grade chronic neck pain to be more associated with cardiovascular conditions when compared to moderate or low-grade chronic pain. Given this information, it is important to assess pain medication burden present in those who have a diagnosis of coronary artery disease and chronic lower back pain.
