Co-prevalence and incidence of myocardial infarction and/or stroke in patients with depression and/or anxiety: A systematic review and meta-analysis.

Objective: Co-prevalence and incidence of depression and/or anxiety with stroke and myocardial infarction are currently unclear. This paper explores the relationships, as these are important comorbidities affecting patient outcomes.

Methods: A systematic search across five databases (PubMed, Scopus, PsycINFO, Embase, Cochrane) was conducted for observational studies reporting co-prevalence of depression or anxiety with stroke or myocardial infarction. We used random-effects models in all meta-analyses and evaluated heterogeneity using I.

Results: This analysis included 48 studies with a total of 57,342 patients. In patients with depression, the pooled prevalence of stroke was 5.9% (95% CI = 5.53-6.37). In patients with myocardial infarction, the pooled prevalence of anxiety and depression was 9.1% (95% CI = 7.07-11.40, I = 85.6%) and 25.9% (95% CI = 18.46-34.12, I = 99.1%), respectively, and the pooled cumulative incidence of depression at one year was 20.5% (95% CI = 18.36-22.79). The pooled prevalence of anxiety and depression in patients with stroke was 13.5% (95% CI = 7.67-22.66, I = 96.9%) and 23.0% (95% CI = 17.93-28.99, I = 96.7%), respectively. The pooled cumulative incidences of depression at two weeks, three months, six months, and one year, were 29.1% (95% CI = 26.60-31.81), 17.0% (95% CI = 10.74-25.92, I = 98.0%), 7.4% (95% CI = 6.52-8.49), and 9.1% (95% CI = 3.71-20.79, I = 99.8%), respectively.

Conclusions: This meta-analysis outlines the co-morbid burden between depression/anxiety and stroke/myocardial infarction. Future research should be done to evaluate the effectiveness of screening anxiety/depression in myocardial infarction/stroke.
