Women with ST-segment elevation myocardial infarction (STEMI) receive suboptimal care and have worse outcomes than men. Whether strategies to reduce STEMI care variability impact disparities in the care and outcomes of women with STEMI is unknown. The study assessed the care and outcomes of men versus women with STEMI before and after implementation of a comprehensive STEMI protocol. On July 15, 2014, the authors implemented: 1) emergency department catheterization lab activation; 2) STEMI Safe Handoff Checklist; 3) immediate transfer to an immediately available catheterization lab; and 4) radial first approach to percutaneous coronary intervention (PCI). The authors prospectively studied consecutive patients with STEMI and assessed guideline-directed medical therapy (GDMT) before PCI, median door-to-balloon time (D2BT), in-hospital adverse events, and 30-day mortality stratified by sex before (January 1, 2011 to July 14, 2014; control group) and after (July 15, 2014 to December 31, 2016) implementation of the STEMI protocol. Of 1,272 participants (68% men, 32% women), women were older with more comorbidities than men. In the control group, women had less GDMT (77% vs. 69%; p = 0.019) and longer D2BT (median 104 min; [interquartile range (IQR): 79 to 133] min vs. 112 [IQR: 85 to 147] min; p = 0.023). Women had more in-hospital stroke, vascular complications, bleeding, transfusion, and death. In the comprehensive 4-step STEMI protocol, sex disparities in GDMT (84% vs. 80%; p = 0.32), D2BT (89 [IQR: 68 to 106] min vs. 91 [IQR: 68 to 114] min; p = 0.15), and in-hospital adverse events resolved. The absolute sex difference in 30-day mortality decreased from the control group (6.1% higher in women; p = 0.002) to the comprehensive 4-step STEMI protocol (3.2% higher in women; p = 0.090). A systems-based approach to STEMI care reduces sex disparities and improves STEMI care and outcomes in women.

Background: We aimed to understand the characteristics and outcomes of patients readmitted with a recurrent myocardial infarction (RMI) within 90 days of discharge after an acute myocardial infarction (early RMI). Methods and Results: We analyzed the timing of reinfarction, etiology, and outcome for all patients admitted with an early RMI within 90 days of discharge after an acute myocardial infarction between January 1, 2010 and January 1, 2017. We identified 6626 admissions for acute myocardial infarction (index myocardial infarction) which led to 168 cases of RMI within 90 days of discharge. The mean patient age was 65.1±13.1 years, and 37% were women. The 90‐day probability of readmission with an early RMI was 2.5%. Black race, medical management, higher troponin T, and shorter length of stay were independent predictors of early RMI. Medically managed group had a higher risk for early RMI compared with percutaneous coronary intervention ( P =0.04) or coronary artery bypass grafting ( P =0.2). Predominant mechanisms for reinfarction were stent thrombosis (17%), disease progression (12%), and unchanged coronary artery disease (11%). At 5 years, the all‐cause mortality rate for patients with an early RMI was 49% (95% CI, 40%–57%) compared with 22% (95% CI, 21%–23%) for patients without an early RMI ( P <0.0001). Conclusions: Early RMI is a life‐threatening condition with nearly 50% mortality within 5 years. Stent‐related events and progression in coronary artery disease account for most early RMI. Medication compliance, aggressive risk factor management, and care transitions should be the cornerstone in preventing early RMI.

Background: Readmission after myocardial infarction ( MI ) is a publicly reported quality metric with hospital reimbursement linked to readmission rates. We describe the timing and pattern of readmission by cause within the first year after MI in consecutive patients, regardless of revascularization strategy, payer status, or age. Methods and Results: We identified patients discharged after an MI from April 2008 to June 2012. Readmission within 12 months was the primary end point. Readmissions were classified into 4 groups: MI related, other cardiovascular, noncardiovascular, and planned. A total of 3069 patients were discharged after an MI (average age, 65±13 years; and 1941 [63%] men). A total of 655 patients (21.3%) were readmitted at least once (897 total readmissions). A total of 147 patients (4.8%) were readmitted ≥2 times, accounting for 389 readmissions (43%). The instantaneous risk of all‐cause readmission was highest (15 readmissions/100 patients per month; 95% confidence interval, 12–19 readmissions/100 patients per month) immediately after discharge, decreased by almost half (8.1 readmissions/100 patients per month; 95% confidence interval, 7.2–9.0 readmissions/100 patients per month) within 15 days, and was substantially lower and relatively constant (1.4 readmissions/100 patients per month; 95% confidence interval, 1.2–1.6 readmissions/100 patients per month) out to 1 year. Cardiovascular causes of readmission were more common early after discharge. Conclusions: Most patients with MI are never readmitted, whereas a small minority (≈5%) account for nearly half of 1‐year readmissions. The readmission pattern after MI is characterized by an early peak (first 15 days) of cardiovascular readmissions, followed by a middle period (months 1–4) of noncardiovascular readmissions, and ending with a low‐risk period (>4 months) during which the risk appears independent of cause.

The unprecedented nature of the COVID-19 pandemic has challenged how and whether patients with heart disease are able to safely access center-based exercise training and cardiac rehabilitation (CR). This commentary provides an experience-based overview of how one health system quickly developed and applied inclusive policies to allow patients to have safe and effective access to exercise-based CR.

The COVID-19 pandemic has dramatically impacted healthcare delivery worldwide. In hotspot areas such as Wuhan, Lombardy, and New York City, the disease has forced hospitals to focus on COVID-19 patients. Anecdotal reports have suggested that the pandemic has led to a decrease in patients presenting to these hospitals with serious cardiovascular and neurologic diseases such as ST-elevation myocardial infarction (STEMI) and stroke. We sought to measure the impact of the COVID-19 pandemic on emergency transfers for STEMI, stroke, and acute aortic emergencies within our regional health system.
