Abstract 18180: Contemporary Nationwide Trends in Major Adverse Cardiac and Cerebrovascular Events in Young Hospitalized Adults With Dependent Cannabis Use in Absence of Concomitant Tobacco, Alcohol or Cocaine Use Disorder, 2016-2019

Abstract

Introduction: Recreational cannabis use has been on the rise among young adults in recent years. Dependent cannabis use disorder (CUD) has been linked to various cardiac events, but its impact on young adults in the absence of concomitant substance abuse remains unclear. We aim to analyze the nationwide trends in hospitalizations for major adverse cardiac and cerebrovascular events (MACCE) in this specific population. Methods: We identified hospitalized young adults (18-44 years) using National Inpatient Sample (2016 -2019), excluding those with concomitant substance abuse (tobacco, alcohol, and cocaine). They were divided into CUD+ and CUD- groups. We assessed the trends in hospitalizations for MACCE, including all-cause mortality (ACM), acute myocardial infarction (AMI), cardiac arrest (CA), and acute ischemic stroke (AIS), using ICD 10 codes. Results: Of 27.4 million hospitalizations among young adults without other substance abuse, 4.2% (1.1 million) had CUD. The rates of hospitalizations for MACCE (1.71% vs. 1.35%), AMI (0.86% vs. 0.54%), CA (0.27% vs. 0.24%), and AIS (0.27 vs. 0.24%), were higher in the CUD+ group compared to the CUD- group (P < 0.001). However, the rate of ACM hospitalizations (0.30% vs. 0.44%) were lower in the CUD+ group. From 2016 to 2019, the CUD+ group exhibited a relative increase of 5% in MACCE and 20% in AMI hospitalizations, which were lower compared to the respective increases of 22% and 36% in the CUD- group (Ptrend<0.05). Additionally, there was a relative decrease of 13% in ACM hospitalizations among the CUD+ group, whereas the CUD- group experienced a relative increase of 10% (Ptrend<0.05). Conclusion: The CUD+ group had higher rates of MACCE admissions, but the growing trends were more pronounced in the CUD- group through the years. Interestingly, the CUD+ group exhibited lower rates of ACM compared to the CUD- group. Further research is needed to better understand this complex relationship.
