We aimed to evaluate the prognostic impact of recreational drug use at 1-year follow-up on major adverse cardiovascular and cerebrovascular events (MACCE) in patients admitted to the ICCU.METHODS: The ADDICT-ICCU study (Addiction in Intensive Cardiac Care Units) is a prospective multicentric study including all consecutive patients admitted to the ICCU over 2 weeks in April 2021 at 39 French centers. Patients were excluded in cases of scheduled hospitalization, hospitalization within 24 hours before ICCU admission, or in-hospital death. Screening for recreational drug use was performed by a systematic urinary testing upon admission. The primary composite outcome was 1-year MACCE defined as cardiovascular death, nonfatal myocardial infarction, or stroke. Outcomes were adjudicated by 2 senior cardiologists after patient contact and review of anonymized records. A multivariable Cox regression analysis adjusted for traditional prognostic factors was performed to assess the independent association between overall recreational drug use and clinical outcomes.RESULTS: Of the 1392 patients assessed (63±15 years, 69.9% men), 157 (11.3%) had an initial positive test (cannabis or opioids, cocaine, amphetamines, or 3,4-methylenedioxymethamphetamine). After 1-year of follow-up, 94 (6.7%) patients experienced MACCE, with a higher incidence observed among drug users compared with nonusers (12.7% versus 6.0%; risk difference, 6.7% [95% CI, 1.5%-12.2%]). Cannabis or opioid use alone was also associated with MACCE (hazard ratio, 1.77 [95% CI, 1.02-3.08] for cannabis, and hazard ratio, 3.60 [95% CI, 1.57-8.23], for opioids). After adjustment for traditional prognostic factors, recreational drug use remained independently associated with MACCE (hazard ratio, 2.91 [95% CI, 1.68-5.05]).CONCLUSIONS: Recreational drug use markedly increases the risk of 1-year adverse cardiovascular outcomes in ICCU patients highlighting the need for targeted, tailored interventions.REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT05063097.PMID:41697269 | DOI:10.1161/CIRCOUTCOMES.124.011905
