Abstract 14204: Impact of Concomitant Tobacco Use on Major Adverse Cardiovascular Events in Young Adults Hospitalized With Known Cannabis Use Disorder

Abstract

Introduction: Cannabis use disorder (CUD) and tobacco use disorder (TUD) are both independent CVD risk factors. However, with the increasing use of recreational cannabis use, the impact of concomitant TUD on major adverse cardiovascular/cerebrovascular events (MACCE) remains unexplored. Hypothesis: Evaluating the impact of concomitant CUD & TUD on MACCE. Methods: We queried 2019's National Inpatient Sample to identify young adults hospitalized with CUD, with vs. without TUD. Baseline demographics, comorbidities, major adverse cardiac events, and the need for revascularization were compared. Multivariable regression analysis was performed, adjusting for confounders to assess the odds of MACCE. Results: Of 539125 patients with CUD, 288260 (53.5%) were TUD+ [median age 31 (25-37)]. TUD+ cohort often had males (60% vs 51.6%), white (58.1% vs 46.8%) patients than TUD- cohort (all p<0.001). The TUD+ cohort showed higher rates of uncomplicated hypertension (15.0% vs 11.6%), alcohol abuse (21.0% vs 12.9%) but lower rates of obesity (9.2% vs. 11.6%), diabetes with chronic complications (4.5% vs. 5.4%), complicated hypertension (3.7% vs 4.4%) and metastatic cancer (0.2% vs. 0.5%) (all p<0.001). After adjusting for covariates, the TUD+ arm had significantly higher odds of acute MI (OR:1.37), Acute PE (OR:1.46), Type 1-DM (OR:1.66), PCI (OR:1.78), CABG (OR:2.62) but lower odds of all-cause mortality (OR:0.55), cardiac arrest including VF (OR:0.59), AF (OR:0.67) and dysrhythmia (OR:0.75) (all p<0.001) [Fig. 1]. The TUD+ cohort incurred lower hospital charges than TUD- cohort (p<0.001). No statistical significance was observed in the odds of stroke and MACCE. Conclusions: Concomitant tobacco & cannabis use had higher odds of Acute MI, PE, PCI and CABG but, interestingly, lower odds of all-cause mortality, dysrhythmia, AF and cardiac arrest including VF. The association between cannabis use and concomitant tobacco use on MACCE needs to be further studied.
