ABSTRACT
BACKGROUND:
Although short-term mortality of acute myocardial infarction (AMI) has decreased dramatically in the past few decades, sudden cardiac arrest remains a serious complication. The aim of the study was to assess the clinical characteristics and predictors of prognosis in AMI patients who experienced out-of-hospital cardiac arrest (OHCA).METHODS:
We retrospectively registered consecutive AMI patients who were treated with emergency percutaneous coronary intervention (PCI) between 2004 and 2017. Clinical characteristics and outcomes were compared between patients with OHCA and those without OHCA.RESULTS:
Among 2101 AMI patients, 95 (4.7%) presented with OHCA. Younger age (odds ratio [OR] 0.95; 95% confidence interval [CI] 0.93-0.97; p < 0.0001), absence of diabetes mellitus (OR, 0.51; 95% CI, 0.30-0.85; p = 0.01) or dyslipidemia (OR, 0.56; 95% CI, 0.36-0.88; p = 0.01), left main trunk (LMT) or left anterior descending artery (LAD) as the culprit lesion (OR, 3.26; 95% CI, 1.99-5.33; p < 0.0001), and renal deficiency (OR, 3.64; 95% CI, 2.27-5.84; p < 0.0001) were significantly associated with incidence of OHCA. Thirty-day mortality was 32.6% in patients with OHCA and 4.5% in those without OHCA. Multivariate logistic analysis revealed LMT or LAD as the culprit lesion (OR, 12.18; 95% CI, 2.27-65.41; p = 0.004), glucose level (OR, 1.01; 95% CI, 1.00-1.01; p = 0.01), and renal deficiency (OR, 3.35; 95% CI, 1.07-10.53; p = 0.04) as independent predictors of 30-day mortality among AMI patients with OHCA.CONCLUSIONS:
In patients with AMI who underwent emergency PCI, 30-day mortality was six times greater in those having presented initially with OHCA compared with those without OHCA. Younger age, absence of diabetes mellitus or dyslipidemia, LMT or LAD as the culprit lesion, and renal deficiency were independent predictors of OHCA. OHCA patient with higher blood glucose level on admission, LMT or LAD as the culprit lesion, or renal deficiency showed worse clinical outcomes.Palavras-chave
