Abstract
Anxiety and anxiety disorders are associated with adverse cardiovascular outcomes, and reduced quality of life. Despite this, no comprehensive study on the global prevalence of anxiety symptoms and disorders among adult cardiology outpatients exists. This systematic review and meta-analysis aims to provide cardiologists with a precise estimate of the prevalence of anxiety in their outpatient clinics. PubMed, Embase, Cochrane and PsycINFO databases and Google Scholar were searched from database inception to January 23, 2023. Data characteristics were extracted independently by 2 investigators. Ninety-three studies, n = 36,687 participants across 31 countries, were included. Global prevalence of anxiety symptoms/disorders was 28.9% (95%CI 25.7-32.4; 8927/36, 687; I2 = 97.33; n = 93). The highest rates were found in patients presenting with hypertension, 43.6%. Subgroup analyses revealed higher prevalence estimates when using self-report screening compared to gold-standard diagnostic interview. When using diagnostic interview, the highest rates were reported in outpatients with undifferentiated chest pain/palpitations, 19·0%. Panic disorder was the most frequent diagnosis 15.3%, and rates were significantly higher in patients with undifferentiated chest pain/palpitations compared to ischemic heart disease. Higher rates of anxiety were found in studies of outpatients from developing countries, and female outpatients tended to have higher rates compared to males. Anxiety occurred frequently among cardiology outpatients and at a higher rate than estimated in the general population. Given the impact anxiety has on patient outcomes, it is important that effective identification and management strategies be developed to support cardiologists in identifying and treating these conditions in their clinics.
