Quality of Life in Patients with Non-CAD Chest Pain: Associations to Fear of Pain and Psychiatric Disorder Severity
Chest pain in the absence of identified cardiac cause, or non-cardiac chest pain (NCCP), is a common condition that may result in impaired quality of life. Theories of NCCP put forward that patients who react to cardiopulmonary sensations with fear may avoid activities that elicit cardiac sensations. Co-morbid psychiatric disorders, which are prevalent in this population, may predispose individuals to be more vigilant to physiological sensations, including cardiac-related symptoms. The daily impact of avoiding cardiopulmonary cues may limit quality of life. This study examined psychiatric disorders, fear of pain, and quality of life in 30 non-coronary artery disease (CAD) chest pain patients. Psychiatric disorder severity was independently associated with mental health related quality of life and fear of pain was independently associated with physical health related quality of life. This research adds understanding to contributory factors to impaired quality of life among patients with non-CAD chest pain.
