Sex Disparities

Background: Sex disparities exist in acute cardiovascular care. Despite sex-specific cardiac arrest (CA) research being identified as a priority by professional societies, there are limited studies on this topic. Objectives: To assess sex disparities in management and outcomes of CA complicating acute myocardial infarction (AMI) in a contemporary United States population. Methods: Adult admissions with a primary diagnosis of AMI and concomitant diagnosis of CA were identified using the National Inpatient Sample. Outcomes of interest included sex disparities in in-hospital mortality, coronary angiography (CAG), percutaneous coronary intervention (PCI) and mechanical circulatory support (MCS) use. Results: Between January 1, 2000 and December 31, 2017, 11,622,528 admissions for AMI were identified, of which 584,216 (5.0%) were complicated by CA. Men had higher prevalence of CA compared to women (5.4% vs 4.4%, p< 0.001) in both STEMI and NSTEMI (2017 vs 2000, STEMI-men: 12.3% vs 7.8%, STEMI-women: 10.4% vs 7.5%, NSTEMI-men: 3.1% vs 2.7%, NSTEMI-women: 2.4% vs 2.5%). Women with AMI-CA were on average older (70.4 vs 65.0, p<0.001), of black race (12.6% vs 7.9%, p<0.001) and had higher comorbidity. Women were more likely to present with NSTEMI (36.4% vs 32.3%, p<0.001) and a non-shockable rhythm (47.6% vs 33.3%, p<0.001). Women less frequently received CAG (56.0% vs 66.2 %), early CAG (32.0% vs 40.2%), PCI (40.4% vs 49.7%), MCS (17.6% vs 22.0%), and CABG (all p<0.001). Women had significantly higher unadjusted in-hospital mortality (52.6% vs 40.6%, p < 0.001). In a multivariable logistic regression analysis, female sex was associated with higher in-hospital mortality (OR 1.13 [95% CI 1.11-1.14]; p< 0.001). When stratified by type of rhythm, type of AMI, presence of cardiogenic shock and location of CA, women consistently received less frequent CAG and experienced higher in-hospital mortality. Conclusion: In the largest 18-year study evaluating management and outcomes of CA in AMI, we identified the presence of significant sex disparities. Women with AMI-CA were older, with higher rates of non-shockable rhythm, were less likely to undergo therapeutic procedures including CAG, PCI, and MCS. Women had higher unadjusted and adjusted in-hospital mortality.

Abstract Background Acute myocardial infarction (AMI) is an uncommon but fatal complication among patients undergoing elective spinal fusion surgery (SF), total hip arthroplasty (THA), and total knee arthroplasty (TKA). Our objective was to estimate the incidence of AMI among adults undergoing elective SF, THA, and TKA in different post-operative risk windows and characterize high-risk sub-populations in the United States. Methods A retrospective cohort study was conducted using data from a longitudinal electronic healthcare record (EHR) database from January 1, 2007 to June 30, 2018. ICD codes were used to identify SF, THA, TKA, AMI, and selected clinical characteristics. Incidence proportions (IPs) and 95% confidence intervals were estimated in the following risk windows: index hospitalization, ≤ 30, ≤ 90, ≤ 180, and ≤ 365 days post-operation. Results A total of 67,533 SF patients, 87,572 THA patients, and 167,480 TKA patients were eligible for the study. The IP of AMI after SF, THA, and TKA ranged from 0.36, 0.28, and 0.25% during index hospitalization to 1.05, 0.93, and 0.85% ≤ 365 days post-operation, respectively. The IP of AMI was higher among patients who were older, male, with longer hospital stays, had a history of AMI, and had a history of diabetes. Conclusion The IP of post-operative AMI was generally highest among the SF cohort compared to the THA and TKA cohorts. Additionally, potential high-risk populations were identified. Future studies in this area are warranted to confirm these findings via improved confounder control and to identify effect measure modifiers.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Lundbeck Foundation OnBehalf Critical Cardiac Care Research Group Background Approximately half of all patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) present with out-of-hospital cardiac arrest (OHCA). Cardiogenic shock due to OHCA is caused by abrupt cessation of circulation, whereas AMICS without OHCA is due to cardiac failure with low cardiac output. Thus, there may also be differences between the two conditions in terms of blood borne biomarkers. Purpose To explore the potential differences in the admission plasma concentrations of biomarkers reflecting tissue perfusion (lactate), neuroendocrine response (mid-regional proadrenomedullin [MRproADM], Copeptin, pro-atrial natriuretic peptide [proANP]), endothelial damage (Syndecan-1, soluble thrombomodulin [sTM]), inflammation (soluble suppression of tumorigenicity 2 [sST2]) and kidney injury (neutrophil gelatinase-associated lipocalin [NGAL]), in patients with AMICS presenting with or without OHCA. Method Consecutive patients admitted for acute coronary angiography due to suspected ST-elevation myocardial infarction (STEMI) were enrolled during a 1-year period. A total of 2,713 patients were screened. In the present study 86 patients with confirmed STEMI and CS at admission were included. Results Patients with OHCA (had significantly higher median admission concentrations of Lactate (6,9 mmol/L vs. 3.4 mmol/L p &lt;0.001), NGAL (220 ng/ml  vs 150 ng/ml p = 0.046), sTM (10 ng/ml vs. 8.0  ng/ml p = 0.026) and Syndecan-1 (160 ng/ml vs. 120 ng/ml p= 0.015) and significantly lower concentrations of MR-proADM (0.85 nmol/L  vs. 1.6 nmol/L p &lt;0.001) and sST2 (39 ng/ml vs. 62 ng/ml p &lt; 0.001).  After adjusting for age, sex, and time from symptom onset to coronary angiography, lactate (p = 0.008), NGAL (p = 0.03) and sTM (p = 0.011) were still significantly higher in patients presenting with OHCA while sST2 was still significantly lower (p = 0.029). There was very little difference in 30-day mortality between the OHCA and non-OHCA groups (OHCA 37% vs. non-OHCA 38%). Conclusion Patients with STEMI and CS at admission with or without concomitant OHCA had similar 30-day mortality but differed in terms of Lactate, NGAL, sTM and sST2 levels at the time of admission to catheterization laboratory. These findings propose that non-OHCA and OHCA patients with CS could be considered as two individual clinical entities. Abstract Figure. Level of biomarkers OHCA vs. non-OHCA
