Aims: COVID-19 might have affected the care and outcomes of hospitalized acute myocardial infarction (AMI). We aimed to determine whether the COVID-19 pandemic changed patient response, hospital treatment, and mortality from AMI. Methods and results: Admission was classified as non-ST-elevation myocardial infarction (NSTEMI) or STEMI at 99 hospitals in England through live feeding from the Myocardial Ischaemia National Audit Project between 1 January 2019 and 22 May 2020. Time series plots were estimated using a 7-day simple moving average, adjusted for seasonality. From 23 March 2020 (UK lockdown), median daily hospitalizations decreased more for NSTEMI [69 to 35; incidence risk ratios (IRR) 0.51, 95% confidence interval (CI) 0.47–0.54] than STEMI (35 to 25; IRR 0.74, 95% CI 0.69–0.80) to a nadir on 19 April 2020. During lockdown, patients were younger (mean age 68.7 vs. 66.9 years), less frequently diabetic (24.6% vs. 28.1%), or had cerebrovascular disease (7.0% vs. 8.6%). ST-elevation myocardial infarction more frequently received primary percutaneous coronary intervention (81.8% vs. 78.8%), thrombolysis was negligible (0.5% vs. 0.3%), median admission-to-coronary angiography duration for NSTEMI decreased (26.2 vs. 64.0 h), median duration of hospitalization decreased (4 to 2 days), secondary prevention pharmacotherapy prescription remained unchanged (each > 94.7%). Mortality at 30 days increased for NSTEMI [from 5.4% to 7.5%; odds ratio (OR) 1.41, 95% CI 1.08–1.80], but decreased for STEMI (from 10.2% to 7.7%; OR 0.73, 95% CI 0.54–0.97). Conclusion: During COVID-19, there was a substantial decline in admissions with AMI. Those who presented to hospital were younger, less comorbid and, for NSTEMI, had higher 30-day mortality.

Prior studies have reported inconsistencies in the baseline risk profile, comorbidity burden and their association with clinical outcomes in women compared to men. More importantly, there is limited data around the sex differences and how these have changed over time in contemporary percutaneous coronary intervention (PCI) practice. We used the Nationwide Inpatient Sample to identify all PCI procedures based on ICD-9 procedure codes in the United States between 2004–2014 in adult patients. Descriptive statistics were used to describe sex-based differences in baseline characteristics and comorbidity burden of patients. Multivariable logistic regressions were used to investigate the association between these differences and in-hospital mortality, complications, length of stay and total hospital charges. Among 6,601,526 patients, 66% were men and 33% were women. Women were more likely to be admitted with diagnosis of NSTEMI (non-ST elevation acute myocardial infarction), were on average 5 years older (median age 68 compared to 63) and had higher burden of comorbidity defined by Charlson score ≥3. Women also had higher in-hospital crude mortality (2.0% vs 1.4%) and any complications compared to men (11.1% vs 7.0%). These trends persisted in our adjusted analyses where women had a significant increase in the odds of in-hospital mortality men (OR 1.20 (95% CI 1.16,1.23) and major bleeding (OR 1.81 (95% CI 1.77,1.86). In this national unselected contemporary PCI cohort, there are significant sex-based differences in presentation, baseline characteristics and comorbidity burden. These differences do not fully account for the higher in-hospital mortality and procedural complications observed in women.

Aims: We hypothesized that a decline in admissions with heart failure during COVID-19 pandemic would lead to a reciprocal rise in mortality for patients with heart failure in the community. Methods and results: We used National Heart Failure Audit data to identify 36 974 adults who had a hospital admission with a primary diagnosis of heart failure between February and May in either 2018, 2019, or 2020. Hospital admissions for heart failure in 2018/19 averaged 160/day but were much lower in 2020, reaching a nadir of 64/day on 27 March 2020 [incidence rate ratio (IRR): 0.40, 95% confidence interval (CI): 0.38–0.42]. The proportion discharged on guideline-recommended pharmacotherapies was similar in 2018/19 compared to the same period in 2020. Between 1 February–2020 and 31 May 2020, there was a 29% decrease in hospital deaths related to heart failure (IRR: 0.71, 95% CI: 0.67–0.75; estimated decline of 448 deaths), a 31% increase in heart failure deaths at home (IRR: 1.31, 95% CI: 1.24–1.39; estimated excess 539), and a 28% increase in heart failure deaths in care homes and hospices (IRR: 1.28, 95% CI: 1.18–1.40; estimated excess 189). All-cause, inpatient death was similar in the COVID-19 and pre-COVID-19 periods [odds ratio (OR): 1.02, 95% CI: 0.94–1.10]. After hospital discharge, 30-day mortality was higher in 2020 compared to 2018/19 (OR: 1.57, 95% CI: 1.38–1.78). Conclusion: Compared with the rolling daily average in 2018/19, there was a substantial decline in admissions for heart failure but an increase in deaths from heart failure in the community. Despite similar rates of prescription of guideline-recommended therapy, mortality 30 days from discharge was higher during the COVID-19 pandemic period.

To assess trends of stroke hospitalization rates, inpatient mortality, and health care resource use in young (aged ≤44 years), midlife (aged 45-64 years), and older (aged ≥65 years) adults. We studied the National Inpatient Sample database (January 1, 2002 to December 31, 2017) to analyze stroke-related hospitalizations. We identified data using the International Classification of Diseases, Ninth/Tenth Revision codes. Of 11,381,390 strokes, 79% (n=9,009,007) were ischemic and 21% (n=2,372,383) were hemorrhagic. Chronic diseases were more frequent in older adults; smoking, alcoholism, and migraine were more prevalent in midlife adults; and coagulopathy and intravenous drug abuse were more common in young patients with stroke. The hospitalization rates of stroke per 10,000 increased overall (31.6 to 33.3) in young and midlife adults while decreasing in older adults. Although mortality decreased overall and in all age groups, the decline was slower in young and midlife adults than older adults. The mean length of stay significantly decreased in midlife and older adults and increased in young adults. The inflation-adjusted mean cost of stay increased consistently, with an average annual growth rate of 2.44% in young, 1.72% in midlife, and 1.45% in older adults owing to the higher use of health care resources. These trends were consistent in both ischemic and hemorrhagic stroke. Stroke-related hospitalization and health care expenditure are increasing in the United States, particularly among young and midlife adults. A higher cost of stay counterbalances the benefits of reducing stroke and mortality in older patients.

Background Patients with underlying cardiovascular disease and Coronavirus disease 2019 (COVID‐19) infection are at increased risk of morbidity and mortality. Objectives This study was designed to characterise the presenting profile and outcomes of patients hospitalized with acute coronary syndrome (ACS) and COVID‐19 infection. Methods This observational cohort study was conducted using multisource data from all acute NHS hospitals in England. All consecutive patients hospitalized with diagnosis of ACS with or without COVID‐19 infection between 1^st March‐ 31^st May 2020 were included. The primary outcome was in‐hospital and 30‐day mortality. Results A total of 12,958 patients were hospitalized with ACS during the study period, of which 517 (4.0%) were COVID‐19 positive and were more likely to present with non‐ST elevation acute myocardial infarction. COVID‐19 ACS group were generally older, Black Asian and Minority ethnicity, more comorbid and had unfavourable presenting clinical characteristics such as elevated cardiac troponin, pulmonary oedema, cardiogenic shock and poor left ventricular systolic function compared with non‐COVID‐19 ACS group. They were less likely to receive an invasive coronary angiography (67.7% vs 81.0%), percutaneous coronary intervention (PCI) (30.2% vs 53.9%) and dual antiplatelet medication (76.3% vs 88.0%). After adjusting for all the baseline differences, patients with COVID‐19 ACS had higher in‐hospital (adjusted odds ratio (aOR) 3.27 95% confidence interval (CI) 2.41‐4.42) and 30‐day mortality (aOR 6.53 95%CI 5.1‐8.36) compared to the non COVID‐19 ACS group. Conclusion COVID‐19 infection was present in 4% of patients hospitalized with an ACS in England and is associated with lower rates of guideline recommended treatment and significant mortality hazard.

Aims: Limited data exist on the impact of COVID-19 on national changes in cardiac procedure activity, including patient characteristics and clinical outcomes before and during the COVID-19 pandemic. Methods and results: All major cardiac procedures (n = 374 899) performed between 1 January and 31 May for the years 2018, 2019, and 2020 were analysed, stratified by procedure type and time-period (pre-COVID: January–May 2018 and 2019 and January–February 2020 and COVID: March–May 2020). Multivariable logistic regression was performed to examine the odds ratio (OR) of 30-day mortality for procedures performed in the COVID period. Overall, there was a deficit of 45 501 procedures during the COVID period compared to the monthly averages (March–May) in 2018–2019. Cardiac catheterization and device implantations were the most affected in terms of numbers (n = 19 637 and n = 10 453), whereas surgical procedures such as mitral valve replacement, other valve replacement/repair, atrioseptal defect/ventriculoseptal defect repair, and coronary artery bypass grafting were the most affected as a relative percentage difference (Δ) to previous years’ averages. Transcatheter aortic valve replacement was the least affected (Δ −10.6%). No difference in 30-day mortality was observed between pre-COVID and COVID time-periods for all cardiac procedures except cardiac catheterization [OR 1.25 95% confidence interval (CI) 1.07–1.47, P = 0.006] and cardiac device implantation (OR 1.35 95% CI 1.15–1.58, P < 0.001). Conclusion: Cardiac procedural activity has significantly declined across England during the COVID-19 pandemic, with a deficit in excess of 45 000 procedures, without an increase in risk of mortality for most cardiac procedures performed during the pandemic. Major restructuring of cardiac services is necessary to deal with this deficit, which would inevitably impact long-term morbidity and mortality.
