The presence of cannabis use disorder (CUD) in elderly patients with peripheral vascular disease (PVD) was found to increase the risk of acute ischemic stroke (AIS). This risk persisted despite controlling for other cardiovascular disease risk factors and substance use.
Background: Given current evidence linking peripheral atherosclerotic disease, also known as cannabis arteritis, and acute ischemic stroke (AIS) in individuals with cannabis use disorder (CUD), we investigated the frequency and implications of CUD in relation to AIS risk and outcomes among elderly patients with peripheral vascular disease (PVD).Methods: The National Inpatient Sample (2016-2019) was used to compare geriatric patients with PVD and cannabis use disorder CUD. CUD was correlated with AIS admissions. Adjusted multi-variable regression models assessed in-hospital mortality rates.Results: Of 5,115,824 geriatric admissions with PVD, 50.6 % were male and 77.5 % were white. 21,405 admissions had cardiovascular and CUD co-occurrence. 19.7 % of CUD patients had diabetes mellitus (DM), compared to 33.7 % of non-CUD patients. Smoking and HTN rates were comparable between groups. Patients with CUD used more recreational drugs concurrently than those without CUD. AIS prevalence was 5.2 % in CUD patients and 4.0 % in controls (p < 0.001). In the geriatric population with PVD, the presence of CUD was found to be associated with increased odds of hospitalizations due to AIS, with an adjusted odds ratio (aOR) of 1.34 (95 % confidence interval [CI] 1.18-1.52, p < 0.001). All-cause in-hospital mortality was not statistically significant, with an aOR of 0.71 (95 %CI 0.36-1.37, p = 0.302). In our study, older patients with PVD and hypertension (aOR 1.73) had a greater risk of AIS. Intriguingly, when we analyzed AIS predictors in elderly PVD patients with concurrent tobacco use disorder, we identified a counterintuitive protective effect (aOR 0.58, 95 % CI 0.42-0.79, p < 0.001).Conclusions: Our findings indicate that among geriatric patients with PVD and concurrent CUD, there is a notable 34 % risk of AIS. Importantly, this risk persists despite controlling for other CVD risk factors and substance use. Further investigations are warranted to elucidate and validate the intriguing phenomenon known as the smoker's paradox.
