A review of the affects of worry and generalized anxiety disorder upon cardiovascular health and coronary heart disease

Objective: The aims of this review article are to present psychophysiological and behavioral pathways for the involvement of worry and generalized anxiety disorder (GAD) upon cardiovascular function. The review will focus on persons with and without coronary heart disease (CHD), and encompass etiological and prognostic studies. Methods: Articles (1975–2011) reporting on GAD or worry affecting CHD prognosis or cardiovascular function were found using MEDLINE, EMBASE, SCOPUS and PsychINFO database searches, and extracted to form a narrative review. Results: Available evidence in experimental and observational studies in CHD free samples consistently showed that worry was associated with diminished heart rate variability (HRV) and elevated heart rate. Worry and GAD were commonly associated with blood pressure and diagnosed hypertension or medication use in both disease-free and established CHD populations. No evidence was found to support worry being beneficial to cardiovascular function or conducive to heal...
