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.

Acute myocardial infarction (AMI) is a leading cause of death in the United States with over three million cases per year. Since the mid-1970s, the total number of deaths related to AMI in the United States has not declined. Studies suggest that women with AMI have worse outcomes compared to men. However, there is limited information regarding this topic among Hispanics. This study was a secondary analysis of the Puerto Rican Heart Attack Study, which reviewed the records of Hispanic patients of Puerto Rico hospitalized for AMI at 21 academic and/or non-teaching hospitals in 2007, 2009 and 2011. This study set examined the differences in in-hospital mortality rates between genders. A p-value of 0.2 was used to select possible confounders and the chi-square test was used to examine associations between categorical variables. Factors associated with in-hospital mortality rates were identified using logistic regression. Collinearity was assessed using Pearson correlation coefficients. The 95% confidence interval and a p-value of 0.05 were used to determine statistical significance of odds ratios. Analysis was restricted to patients with ICD-9-CM code 410-414 who are above 18 (n = 2265). In our sample, there were more men than women (1291 versus 974, respectively). Men were younger and smoked more compared to women. Compared to men, women were older and suffered more comorbidities, such as stroke and congestive heart failure (CHF). Women had higher rates of in-hospital mortality compared to men (OR = 1.4, p = 0.040). Factors associated with higher rates of in-hospital mortality included age and CHF (p<0.001). Patients with CHF showed higher rates of in-hospital deaths compared to patients who did not have CHF (OR = 1.6, p = 0.026). Patients over the age of 86 showed higher odds of in-hospital death compared to younger patients (OR = 10.5, p <0.001) Significant disparities existed by gender in this sample of Hispanic AMI patients, with women showing higher in-hospital mortality compared to men. Women over 50 should perform regular checkups and discuss hormone replacement therapy or follow other preventive measures as suggested by their healthcare provider.

Objectives: Because inter- and intra-country variations in the adoption of medical technologies exist, international comparative studies provide an opportunity to infer technology effectiveness. Few studies have characterized recent trends in acute myocardial infarction (AMI) management between countries. Methods: Repeated cross-sectional observational cohorts of hospitalized adults aged ≥20 years discharged between January 2000 and December 2010. We identified new AMI hospitalizations using a US national 20% inpatient sample and a 100% inpatient sample in all Portuguese public sector hospitals. Age, sex, comorbidities, and median length of stay (interquartile range [IQR]) were determined. Annual age-sex adjusted hospitalization rates (HR) for AMI, in-hospital procedures, and in-hospital mortality were directly standardized to the 2010 US population. Intra-country (2010 relative to 2000) and inter-country in 2010 (Portugal [PT] relative to US) rate ratios [RR] were estimated. Findings: We identified 1476808 AMI US hospitalizations and 126314 Portugal hospitalizations between 2000 and 2010. Portuguese patients were more male, younger, and had fewer comorbidities compared to US patients (Table). The age-sex adjusted AMI HR decreased from 21 per 1000 person-years to 15 in the US (RR=0.70; 95% CI = [0.70, 0.71]) but increased in PT (14 to 15 per 1000, RR = 1.17 [1.14, 1.21]). While crude procedure rates were uniformly lower in PT, only CABG rates differed after standardization (2010: RR=0.19 [0.14, 0.26]). PCI use increased annually in both countries and decreased for CABG in the US only (102 to 79, RR=0.77 [0.73, 0.81]). Standardized in-hospital mortality decreased within-country (US: 44 to 29 per 1000, RR= 0.65 [0.60, 0.72]; PT: 93 to 62 per 1000, RR= 0.67 [0.44, 1.00]). In 2010, PT mortality was twice that in the US. Conclusions: AMI hospitalization rates and use of medical technologies are higher in the US compared to Portugal. However, standardized rates reveal only CABG surgery rates differ significantly between the two countries. Outcomes, measured by hospital mortality and LOS, are generally better in the U.S. Inter-country disparities may be a consequence of differential use of technologies, differences in AMI epidemiology, patient risk, or quality of hospital billing data.

Introduction: There is a paucity of contemporary data on the burden of intracranial hemorrhage (ICH) complicating acute myocardial infarction (AMI). Methods: The National Inpatient Sample database (2000 to 2017) was used to evaluate in-hospital burden of ICH in adult (>18 years) AMI admissions. In-hospital mortality, hospitalization costs, length of stay, and measure of functional ability were the outcomes of interest. The discharge destination along with use of tracheostomy and percutaneous endoscopic gastrostomy (PEG) were used to estimate functional burden. Results: Of a total 11,622,528 AMI admissions, 23,422 (0.2%) had concomitant ICH. Compared to those without, admissions with ICH were on average older, female, of non-White race, with greater comorbidities, and higher rates of arrhythmias (all p<0.001). Female sex, non-White race, ST-segment-elevation AMI presentation, use of fibrinolytics, mechanical circulatory support and invasive mechanical ventilation were identified as individual predictors of ICH. The AMI admissions with ICH received less frequent coronary angiography (46.9% vs. 63.8%), percutaneous coronary intervention (22.7% vs. 41.8%), and coronary artery bypass grafting (5.4% vs. 9.2%) as compared to those without (all p<0.001). ICH was associated with a significantly higher in-hospital mortality (41.4% vs. 6.1%; adjusted OR 5.65 [95% CI 5.47-5.84]; p<0.001), and adjusted temporal trends showed a steady decrease in in-hospital mortality over the 18-year period (Figure 1A). AMI-ICH admissions also had longer hospital length of stay, higher hospitalization costs, and greater use of PEG (all p<0.001). In AMI-ICH survivors (N=13, 689), 81.3% had a poor functional outcome indicating severe morbidity and temporal trends revealed a slight increase over the study period (Figure 1B). Conclusions: ICH causes a substantial burden in AMI due to associated higher in-hospital mortality, resource utilization, and poor functional outcomes.

Significant Difference

Background: The overall mortality rate after acute myocardial infarction (AMI) is falling in the United States. However, outcomes remain unacceptably worse in females compared to males. It is not known how coexisting atrial fibrillation (AF) modify outcomes among the sexes. We sought to examine the association of sex with clinical characteristics and outcomes after AMI among patients with AF. Methods: We accessed the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS), to extract all hospitalizations between 2007 and 2011 for patients above 18yrs with principal diagnosis of AMI and coexisting diagnosis of AF using ICD 9-CM codes. The NIS represents the largest all-payer hospitalization database in the United States, sampling approximately 8 million hospitalizations per year. We also extracted outcomes data (length of stay (LOS), stroke and in-hospital mortality) after AMI among Patients with AF. We then compared sex differences. Univariate and Multivariate analysis were conducted to determine the presence of statistically significant difference in outcomes between men and women. Results: A total of 184,584 AF patients with AMI were sampled, consisting of 46.82% (86,420) women and 53.13% (98,164) men. Compared with men, women with AF and AMI had a greater multivariate-adjusted risk for increased stroke rate (aOR=1.51, 95% CI=1.45-1.59), and higher in-hospital mortality (aOR=1.12, 95% CI=1.09-1.15). However, female gender was not significantly associated with longer LOS (aOR=-0.22, 95% CI= -0.29-(-0.14). Conclusion: In this large nationwide study of a population-based cohort, women experienced worse outcomes after AMI among patients with AF. They had higher in-hospital mortality and increased stroke rates. Our findings highlight the need for targeted interventions to improve these disparities in outcomes.
