Nationwide Trends in Cardiovascular and Cerebrovascular Diseases and Outcomes Among Young Adults (18-39 years) Hospitalized With Comorbid Depression

Background Modern-day studies that assess temporal trends in cardiovascular and cerebrovascular events (CCE) and outcomes among the young population in the United States (US) with depression remain limited. Methods We compared baseline demographics, comorbidities, all-cause mortality, acute myocardial infarction (AMI), percutaneous coronary interventions (PCI), arrhythmia, stroke, and venous thromboembolism (VTE) among hospitalized young adults (18-39 years) with vs. without depression using the National Inpatient Sample (NIS) from 2007 to 2014. Results A total of 3,575,275 patients out of 63,020,008 hospitalized young adults had comorbid depression (5.7%; median 31 years, 71.3% females). The depressed cohort more often comprised of older, white, male, and non-electively admitted patients. Higher rates of comorbidities, all-cause mortality, PCI, arrhythmia, VTE, and stroke were observed among the depressed cohort. The rising trend in all-cause mortality was observed among the depressed against a stable trend in the non-depressed. The prevalence of AMI remained stable among depressed with consistent upsurges in arrhythmia and stroke. Those with depression had extended hospital stay, higher hospitalization charges, and were more often transferred to other facilities or discharged against advice. Conclusions Rising trends of inpatient mortality, CCE, and higher resource utilization among young adults with depression are concerning and warrants a multidisciplinary approach to improve quality of life and outcomes.
