In-hospital prognosis of acute ST-elevation myocardial infarction in patients with recent recreational drug use.

AIMS: Although recreational drug use may induce ST-elevated myocardial infarction (STEMI), its prevalence in patients hospitalized in intensive cardiac care units (ICCUs), as well as its short-term cardiovascular consequences, remains unknown. We aimed to assess the in-hospital prognosis of STEMI in patients with recreational drug use from the ADDICT-ICCU study. METHODS AND RESULTS: From 7-22 April 2021, recreational drug use was detected prospectively by a systematic urine multidrug test in all consecutive patients admitted for STEMI in 39 ICCUs across France. The primary endpoint was major adverse cardiac events (MACEs) defined by death, resuscitated cardiac arrest, or cardiogenic shock. Among the 325 patients (age 62 ± 13 years, 79% men), 41 (12.6%) had a positive multidrug test (cannabis: 11.1%, opioids: 4.6%, cocaine: 1.2%, 3,4-methylenedioxymethamphetamine: 0.6%). The prevalence increased to 34.0% in patients under 50 years of age. Recreational drug users were more frequently men (93% vs. 77%, p = 0.02), younger (50 ± 12 years vs. 63 ± 13 years, P < 0.001), and more active smokers (78% vs. 34%, P < 0.001). During hospitalization, 17 MACEs occurred (5.2%), including 6 deaths (1.8%), 10 cardiogenic shocks (3.1%), and 7 resuscitated cardiac arrests (2.2%). Major adverse cardiac events (17.1% vs. 3.5%, P < 0.001) and ventricular arrhythmia (9.8% vs. 1.4%, P = 0.01) were more frequent in recreational drug users. Use of recreational drugs was associated with more MACEs after adjustment for comorbidities (odds ratio = 13.1; 95% confidence interval: 3.4-54.6). CONCLUSION: In patients with STEMI, recreational drug use is prevalent, especially in patients under 50 years of age, and is independently associated with an increase of MACEs with more ventricular arrhythmia.

Prevention and treatment of premature ischaemic heart disease with European Society of Cardiology Guidelines.

OBJECTIVE: To determine if the changes in the European Society Cardiology/European Atherosclerotic Society (ESC/EAS) guidelines improved the identification for primary prevention therapy in young adults at risk of a premature myocardial infarction. METHODS: Patients admitted for a first ST-segment elevation myocardial infarction (STEMI) in the ePARIS registry (n=2757) between 2010 and 2018 were classified by age: <55, 55-65 and >65 years old. Using Systematic Coronary Risk Estimation 2, we evaluated whether patients would have been detected and treated with primary prevention statins before their first STEMI based on the 2021 EAS/ESC guidelines versus 2019 and 2016 guidelines. Eligibility for intensive proprotein convertase subtilisin/kexin type 9 (PCSK9i) in secondary prevention was also assessed. RESULTS: Following 2021 ESC guidelines, 62.5% of individuals aged <55 years old would have been eligible for statins before their first STEMI, similarly to older age categories. In comparison, only 17% and 18% of young individuals would have been eligible for primary prevention statins prior to their first STEMI with 2016 and 2019 guidelines, compared with group 55-65 years (41% and 35%) and >65 years old (19% and 72%), p<0.01. After their first STEMI, 25% of patients <55 years would be eligible for PCSK9i, compared with 23.2% and 15% in patients aged 55-65 years and >65 years. CONCLUSIONS: The 2021 ESC guidelines allowed a much better detection of young individuals before their first STEMI than prior ESC guidelines. In secondary prevention, most of young individuals did not reach low-density lipoprotein cholesterol levels recommended, but only one quarter would be eligible for PCSK9i.

ESC/EAS guidelines for the detection, prevention, and treatment of individuals at risk of a first myocardial infarction: effect of 5 years of updates and the new SCORE2.

AIMS: The European Society of Cardiology (ESC) has released three consecutive guidelines within 5 years addressing cardiovascular prevention, risk scores, and cholesterol treatment. This study aims to evaluate whether the 2021 ESC guidelines improved the eligibility of individuals for primary prevention statin therapy before their first ST-segment elevation myocardial infarction (STEMI), and for intensive lipid-lowering treatments in secondary prevention. METHODS AND RESULTS: The cardiovascular risk category of 2757 consecutive individuals admitted for a first STEMI was evaluated to assess whether they would have been eligible for primary prevention statins according to 2021 vs. 2019 and 2016 ESC guidelines. Eligibility for intensive lipid-lowering therapy in secondary prevention was assessed according to the real-life follow-up low-density lipoprotein cholesterol (LDL-C) and the expected follow-up LDL-C. More individuals would have been eligible for primary prevention statins according to 2021 and 2019 vs. 2016 guidelines (61.8% vs. 38.7% vs. 23.6%, P < 0.01), a finding observed in both men (62.3% vs. 35.0% vs. 24.9%, P < 0.01) and women (60.2% vs. 50.7% vs. 19.3%, P = 0.18). Only 27% of individuals reached the LDL-C objective of 55 mg/L in secondary prevention: using the ESC stepwise approach, 61.7% were eligible for higher doses of statins, 26.2% for ezetimibe, and 12.1% for a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor (PCSK9i). Based on expected LDL-C reductions, eligibility for a PCSK9i in secondary prevention was greater with 2021 vs. 2016 guidelines (44.5% vs. 22.5%, P < 0.01). CONCLUSION: The 2021 ESC guidelines improved the detection and treatment of individuals at risk for a first myocardial infarction. In secondary prevention, 70% of patients kept LDL-C levels above 55 mg/dL: increasing the statin dose and adding ezetimibe were the most frequently recommended therapeutic actions.
