Differences in clinical features according to survival and gender in patients admitted for cardiac arrest
European Heart Journal: Acute Cardiovascular Care(2024)
摘要
Abstract Funding Acknowledgements None. Introduction Cardiac arrest (CA) is a condition with poor vital and neurological prognosis. Although there are widely known clinical features modifying prognosis –such as time to return of spontaneous circulation (ROSC) and neuron-specific enolase values-, there is uncertainty around whether gender, ischemic etiology or classic cardiovascular risk factors may influence in the management and prognosis. Purpose The aim of this study was to analyze the differences in baseline characteristics and management between survivors and non survivors, among patients admitted for CA in an Intensive Cardiac Care Unit. Methods A prospective unicentric registry was performed from January 2010 to December 2021, including all consecutive cardiac arrest patients admitted to an intensive cardiac care unit of a university hospital. Patients were classified into survivors –to hospital discharge- and non-survivors –deceased during hospital admission, irrespective of time of death. Univariate analysis were performed using Chi-square and Student t tests, and logistic regression was used for a multivariate analysis to compare both groups. Results A total of 324 patients were included, mean age 59.7 (DE 12.2) years, 17.9% were women. In-hospital mortality was 42% (136 patients) and 188 patients survived to hospital discharge. Survivors were significantly younger (mean of 57,37 vs 62,98 years) and had less prevalence of diabetes (17 vs 33%) and previous myocardial infarction (15 vs 25%) than non-survivors. Among survivors, there was a higher prevalence of in-hospital CA (26,6 vs 12,5%), CA due to acute coronary syndrome (68,62 vs 57,78%) and shockable first rhythm (90,43 vs 72,06%). They also had shorter ROSC (mean 22,13 vs 34,25 minutes) and no flow times (mean 2,54 vs 5,67 minutes). Gender, arterial hypertension, dyslipidemia and smoking habit did not modify prognosis. When comparing genders, women had significantly less prevalence of smoking habit and previous ischemic heart disease, their time to ROSC was lower and they received less coronary angiographies than men. The multivariate analysis showed significant in-hospital mortality risk increase with age (OR 1,04 per year), ROSC (OR 1,04 per minute) and no-flow (OR 1,09 per minute) times, out of hospital CA (OR 2,26) and non shockable rhythm. Conclusions In a consecutive cohort of 324 patients admitted after cardiac arrest, survivors were significantly younger, and had less prevalence of diabetes mellitus and previous myocardial infarction. In-hospital arrest, shockable rhythm, and shorter ROSC and no-flow times were associated with better survival. No differences in survival were found between genders, although women had significantly shorter resuscitation times.Univariate analysisMultivariate analysis
