    We hypothesized that the insensitivity of the electrocardiogram. in identifying acute circumflex occlusion would result in differences in the distribution of the infarct-related artery (IRA) between patients with non ST-segment elevation myocardial infarction (NSTEMI) and STEMI enrolled in the Occluded Artery Trial. We also sought to evaluate the effect of percutaneous coronary intervention to the IRA on the clinical outcomes for patients with NSTEMI. Overall, those with NSTEMI constituted 13% (n = 283) of the trial population. the circumflex IRA was overrepresented in the NSTEMI group compared to the STEM! group (42.5 vs 11.2%; p < 0.0001). the 7-year clinical outcomes for the patients with NSTEMI randomized to percutaneous coronary intervention and optimal medical therapy versus optimal medical therapy alone were similar for the primary composite of death, myocardial infarction, and class W congestive heart failure (22.3% vs 20.2%, hazard ratio 1.20, 99% confidence interval 0.60 to 2.40; p = 0.51) and the individual end points of death (13.8% vs 17.0%, hazard ratio 0.82, 99% confidence interval 0.37 to 1.84; p = 0.53), myocardial infarction (6.1 vs 5.1%, hazard ratio 1.11, 99% confidence interval 0.28 to 4.41; p = 0.84), and class IV congestive heart failure (6.7% vs 6.0%, hazard ratio 1.50, 99% confidence interval 0.37 to 6.02; p = 0.45). No interaction was seen between the electro-cardiographically determined myocardial infarction type and treatment effect (p = NS). in conclusion, the occluded circumflex IRA is overrepresented in the NSTEMI population. Consistent with the overall trial results, stable patients with NSTEMI and a totally occluded IRA did not benefit from randomization to percutaneous coronary intervention. (C) 2013 Elsevier Inc.

    No full text
    International audienceBackground: Intensive cardiac care units (ICCU) were initially developed to monitor ventricular arrhythmias after myocardial infarction. In recent decades, ICCU have diversified their activities.Aim: To determine the type of patients hospitalized in ICCU in France.Methods: We analysed the characteristics of patients enrolled in the ADDICT-ICCU registry (NCT05063097), a prospective study of consecutive patients admitted to ICCU in 39 centres throughout France from 7th-22nd April 2021. In-hospital major adverse events (MAE) (death, resuscitated cardiac arrest and cardiogenic shock) were recorded.Results: Among 1499 patients (median age 65 [interquartile range 54-74] years, 69.6% male, 21.7% diabetes mellitus, 64.7% current or previous smokers), 34.9% had a history of coronary artery disease, 11.7% atrial fibrillation and 5.2% cardiomyopathy. The most frequent reason for admission to ICCU was acute coronary syndromes (ACS; 51.5%), acute heart failure (AHF; 14.1%) and unexplained chest pain (6.8%). An invasive procedure was performed in 36.2%. "Advanced" ICCU therapies were required for 19.9% of patients (intravenous diuretics 18.4%, non-invasive ventilation 6.1%, inotropic drugs 2.3%). No invasive procedures or advanced therapies were required in 44.1%. Cardiac computed tomography or magnetic resonance imaging was carried out in 12.3% of patients. The median length of ICCU hospitalization was 2.0 (interquartile range 1.0-4.0) days. The mean rate of MAE was 4.5%, and was highest in patients with AHF (10.4%).Conclusions: ACS remains the main cause of admissions to ICCU, with most having a low rate of in-hospital MAE. Most patients experience a brief stay in ICCU before being discharged home. AHF is associated with highest death rate and with higher resource consumption

    International audienceBackground: Psychoactive drugs, including illicit drugs, are associated with an increased rate of cardiovascular events. The prevalence and outcome of patients using these drugs at the time of admission to an intensive cardiac care unit is unknown.Aim: To assess the prevalence of psychoactive drugs detected in consecutive patients hospitalized in an intensive cardiac care unit for an acute cardiovascular event.Methods: This is a nationwide prospective multicentre study, involving 39 centres throughout France, including all consecutive patients hospitalized in an intensive cardiac care unit within 2weeks. Psychoactive drug use will be assessed systematically by urine drug assay within 2hours of intensive cardiac care unit admission, to detect illicit (cannabinoids, cocaine, amphetamines, ecstasy, heroin and other opioids) and non-illicit (barbiturates, benzodiazepines, tricyclic antidepressants, methadone and buprenorphine) psychoactive drugs. Smoking will be investigated systematically by exhaled carbon monoxide measurement, and alcohol consumption using a standardized questionnaire. In-hospital major adverse events, including death, resuscitated cardiac arrest and cardiogenic shock, will be recorded. After discharge, all-cause death and major adverse cardiovascular events will be recorded systematically and adjudicated at 12months of follow-up.Results: The primary outcome will be the prevalence of psychoactive drugs detected by systematic screening among all patients hospitalized in an intensive cardiac care unit. The in-hospital major adverse events will be analysed according to the presence or absence of detected psychoactive drugs. Subgroup analysis stratified by initial clinical presentation and type of psychoactive drug will be performed.Conclusions: This is the first prospective multicentre study to assess the prevalence of psychoactive drugs detected by systematic screening in consecutive patients hospitalized for acute cardiovascular events

    International audienceBackground: The COVID-19 pandemic has had a profound effect on general health care. We aimed to evaluate the effect of a nationwide lockdown in France on admissions to hospital for acute myocardial infarction, by patient characteristics and regional prevalence of the pandemic.Methods: In this registry study, we collected data from 21 centres participating in the ongoing French Cohort of Myocardial Infarction Evaluation (FRENCHIE) registry, which collects data from all patients admitted for ST segment elevation myocardial infarction (STEMI) or non-ST segment elevation myocardial infarction (NSTEMI) within 48 h of symptom onset. We analysed weekly hospital admissions over 8 weeks: the 4 weeks preceding the institution of the lockdown and the 4 weeks following lockdown. The primary outcome was the change in the number of hospital admissions for all types of acute myocardial infarction, NSTEMI, and STEMI between the 4 weeks before lockdown and the 4 weeks after lockdown. Comparisons between categorical variables were made using χ2 tests or Fisher's exact tests. Comparisons of continuous variables were made using Student's t tests or Mann-Whitney tests. Poisson regression was used to determine the significance of change in hospital admissions over the two periods, after verifying the absence of overdispersion. Age category, region, and type of acute myocardial infarction (STEMI or NSTEMI) were used as covariables. The FRENCHIE cohort is registered with ClinicalTrials.gov, NCT04050956.Findings: Between Feb 17 and April 12, 2020, 1167 patients were consecutively admitted within 48 h of acute myocardial infarction (583 with STEMI, 584 with NSTEMI) and were included in the study. Admissions for acute myocardial infarction decreased between the periods before and after lockdown was instituted, from 686 before to 481 after lockdown (30% decrease; incidence rate ratio 0·69 [95% CI 0·51-0·70]). Admissions for STEMI decreased from 331 to 252 (24%; 0·72 [0·62-0·85]), and admissions for NSTEMI decreased from 355 to 229 (35%; 0·64 [0·55-0·76]) following institution of the lockdown, with similar trends according to sex, risk factors, and regional prevalence of hospital admissions for COVID-19.Interpretation: A marked decrease in hospital admissions was observed following the lockdown, irrespective of patient characteristics and regional prevalence of COVID-19. Health authorities should be aware of these findings, in order to adapt their message if the COVID-19 pandemic persists or recurs, or in case of future major epidemics

    Summary: Background: Smoking cigarettes produces carbon monoxide (CO), which can reduce the oxygen-carrying capacity of the blood. We aimed to determine whether elevated expiratory CO levels would be associated with a worse prognosis in smokers presenting with acute cardiac events. Methods: From 7 to 22 April 2021, expiratory CO levels were measured in a prospective registry including all consecutive patients admitted for acute cardiac event in 39 centres throughout France. The primary outcome was 1-year all-cause death. Initial in-hospital major adverse cardiac events (MAE; death, resuscitated cardiac arrest and cardiogenic shock) were also analysed. The study was registered at ClinicalTrials.gov (NCT05063097). Findings: Among 1379 patients (63 ± 15 years, 70% men), 368 (27%) were active smokers. Expiratory CO levels were significantly raised in active smokers compared to non-smokers. A CO level >11 parts per million (ppm) found in 94 (25.5%) smokers was associated with a significant increase in death (14.9% for CO > 11 ppm vs. 2.9% for CO ≤ 11 ppm; p  11 ppm was associated with a significant increase in MAE in smokers during initial hospitalisation after adjustment for comorbidities (odds ratio [OR] 15.75, 95% CI [5.56–44.60]) or parameters of in-hospital severity (OR 10.67, 95% CI [4.06–28.04]). In the overall population, CO > 11 ppm but not smoking was associated with an increased rate of all-cause death (HR 4.03, 95% CI [2.33–6.98] and 1.66 [0.96–2.85] respectively). Interpretation: Elevated CO level is independently associated with a 6-fold increase in 1-year death and 10-fold in-hospital MAE in smokers hospitalized for acute cardiac events.
