Although certain risk factors have been associated with morbidity and mortality, validated emergency department (ED) derived risk prediction models specific to coronavirus disease 2019 (COVID-19) are lacking. The objective of this study is to describe and externally validate the COVID-19 risk index (CRI). A large retrospective longitudinal cohort study was performed to analyze consecutively hospitalized patients with COVID-19. Multivariate regression using clinical data elements from the ED was used to create the CRI. The results were validated with an external cohort of 1799 patients from the MI-COVID19 database. The primary outcome was the composite of the need for mechanical ventilation or inpatient mortality, and the secondary outcome was inpatient mortality. A total of 1020 patients were included in the derivation cohort. A total of 236 (23%) patients in the derivation cohort required mechanical ventilation or died. Variables independently associated with the primary outcome were age ≥ 65 years, chronic obstructive pulmonary disease, chronic kidney disease, cerebrovascular disease, initial D-dimer > 1.1 µg/mL, platelet count

The use of mechanical circulatory devices to support high-risk elective percutaneous coronary intervention (PCI) has become more common as the group of patients considered inoperable or high risk for surgical revascularization has grown. Most of the data examining outcomes in high-risk PCI are observational and retrospective. Limited prospective randomized studies have been unable to show improved clinical outcomes with routine mechanical circulatory support (MCS) in patients with a high burden of coronary artery disease and reduced ejection fraction. The role for MCS in high-risk PCI continues to evolve as understanding of the appropriate groups for this therapy evolves.

Patients with atrial fibrillation or flutter (AF) on anticoagulation (AC) for stroke prevention are at an increased risk of bleeding. A common clinical dilemma is deciding when to safely restart AC following a bleed. Although studies have shown better outcomes with re-initiation of AC after hemostasis, there are clinical barriers to restarting AC. Left atrial appendage occlusion (LAAO) is a safe and efficacious alternative for patients who are unable to tolerate AC following major bleeding. We aimed to evaluate the rate of stroke prevention strategies instituted at time of discharge in patients with AF on AC who had been hospitalized for a bleeding event. We retrospectively identified patients with AF on AC admitted for bleeding between January 2016 and August 2019. The type of AC, form of bleeding, and CHA2DS2VASc were collected. Stroke prevention strategies upon discharge and at 3 months were noted. One hundred seventy-four patients with AF on AC were hospitalized with a bleeding event, of which 10.9% died. Among patients who survived, AC was restarted in 45.2% of patients, 9.7% were referred for LAAO, and 45.1% were discharged without stroke prevention strategy. At 3 months, 32.6% of patients still had no documented stroke prophylaxis. Those referred for LAAO had, on average, higher CHA2DS2VASc (5 ± 1 vs 4 ± 1, p = 0.007). A significant number of patients with AF hospitalized for bleeding were discharged with no plan for stroke prophylaxis. Despite its safety and efficacy, LAAO appears to be an underutilized alternative in AF patients with high bleeding risk.

Although certain risk factors have been associated with increased morbidity and mortality in patients admitted with Coronavirus Disease 2019 (COVID-19), the impact of cardiac injury and high-sensitivity troponin-I (hs-cTnI) concentrations are not well described. In this large retrospective longitudinal cohort study, we analyzed the cases of 1,044 consecutively admitted patients with COVID-19 from March 9 until April 15. Cardiac injury was defined by hs-cTnI concentration >99th percentile. Patient characteristics, laboratory data, and outcomes were described in patients with cardiac injury and different hs-cTnI cut-offs. The primary outcome was mortality, and the secondary outcomes were length of stay, need for intensive care unit care or mechanical ventilation, and their different composites. The final analyzed cohort included 1,020 patients. The median age was 63 years, 511 (50% patients were female, and 403 (40% were white. 390 (38%) patients had cardiac injury on presentation. These patients were older (median age 70 years), had a higher cardiovascular disease burden, in addition to higher serum concentrations of inflammatory markers. They also exhibited an increased risk for our primary and secondary outcomes, with the risk increasing with higher hs-cTnI concentrations. Peak hs-cTnI concentrations continued to be significantly associated with mortality after a multivariate regression controlling for comorbid conditions, inflammatory markers, acute kidney injury, and acute respiratory distress syndrome. Within the same multivariate regression model, presenting hs-cTnI concentrations were not significantly associated with outcomes, and undetectable hs-cTnI concentrations on presentation did not completely rule out the risk for mechanical ventilation or death. In conclusion, cardiac injury was common in patients admitted with COVID-19. The extent of cardiac injury and peak hs-cTnI concentrations were associated with worse outcomes.

The aim of this study was to evaluate the combined impact of race, ethnicity, and sex on in-hospital outcomes using data from the National Inpatient Sample.Cardiogenic shock (CS) is a major cause of mortality following ST-segment elevation myocardial infarction (STEMI). Early revascularization reduces mortality in such patients. Mechanical circulatory support (MCS) devices are increasingly used to hemodynamically support patients during revascularization. Little is known about racial, ethnic, and sex disparities in patients with STEMI and CS.The National Inpatient Sample was queried from January 2006 to September 2015 for hospitalizations with STEMI and CS. The associations between sex, race, ethnicity, and outcomes were examined using complex-samples multivariate logistic or generalized linear model regressions.Of 159,339 patients with STEMI and CS, 57,839 (36.3%) were women. In-hospital mortality was higher for all women (range 40% to 45.4%) compared with men (range 30.4% to 34.7%). Women (adjusted odds ratio [aOR]: 1.11; 95% confidence interval [CI]: 1.06 to 1.16; p 0.001) as well as Black (aOR: 1.18; 95% CI: 1.04 to 1.34; p = 0.011) and Hispanic (aOR: 1.19; 95% CI: 1.06 to 1.33; p = 0.003) men had higher odds of in-hospital mortality compared with White men, with Hispanic women having the highest odds of in-hospital mortality (aOR: 1.46; 95% CI: 1.26 to 1.70; p 0.001). Women were older (age: 69.8 years vs. 63.2 years), had more comorbidities, and underwent fewer invasive cardiac procedures, including revascularization, right heart catheterization, and MCS.There are significant racial, ethnic, and sex differences in procedural utilization and clinical outcomes in patients with STEMI and CS. Women are less likely to undergo invasive cardiac procedures, including revascularization and MCS. Women as well as Black and Hispanic patients have a higher likelihood of death compared with White men.

A 67-year-old woman presented with upper respiratory symptoms and was diagnosed with coronavirus disease-2019 (COVID-19). She was found to have a large hemorrhagic pericardial effusion with echocardiographic signs of tamponade and mild left ventricular impairment. Clinical course was complicated by development of takotsubo cardiomyopathy. She was treated with pericardiocentesis, colchicine, corticosteroids, and hydroxychloroquine, with improvement in symptoms. (Level of Difficulty: Intermediate.)

Background Cardiovascular comorbidities and complications, including right ventricular dysfunction, are common and are associated with worse outcomes in patients with COVID-19. The data on the clinical utility of 12-lead electrocardiograms (ECG) to aid with prognosis is limited. Objectives We aim to assess the association of new right heart strain patterns on presenting 12-lead electrocardiogram (RHS-ECG) with outcomes in patients hospitalized with COVID-19. Methods We retrospectively evaluated records from 480 patients who were consecutively admitted with COVID-19. ECGs obtained at the time of presentation in the emergency department (ED) were considered as index ECGs. RHS-ECG was defined by any new right axis deviation, S1Q3T3 pattern, or ST depressions with T-wave inversions in leads V1-3 or II, III, aVF. Multivariable logistic regression was performed to assess whether RHS-ECG is independently associated with our primary outcomes. Results ECGs from the ED were available for 314 patients who were included in the analysis. Most patients were in sinus rhythm, with sinus tachycardia being the most frequent dysrhythmia. RHS-ECG findings were present in 40 (11%) patients. RHS-ECG was significantly associated with the incidence of adverse outcomes and an independent predictor of mortality (adjOR, 15.2 (95% [CI, 5.1-45.2]; P, Graphical abstract, Cardiovascular complications are associated with worse outcomes in COVID-19. The present study evaluates the likelihood of critical illness in patients who have new right heart strain patterns on presenting 12-lead electrocardiogram (RHS-ECG). RHS-ECG was defined by any new right axis deviation, S1Q3T3 pattern, or ST Depressions with T-wave inversions in leads V1-3 or II, III, aVF. Our results revealed that RHS-ECG was the strongest independent predictor of mechanical ventilation and mortality in multivariable analysis with a powerful discriminatory ability as early as the ED encounter. A structured approach is warranted for patients admitted with RHS-ECG.

Introduction Cardiovascular comorbidities confer worse outcomes for patients with Coronavirus disease 2019 (COVID-19), but the impact of heart failure (HF) with preserved (HFpEF) and reduced (HFrEF) ejection fraction has not been well characterized. The aim herein is to examine outcomes in COVID-19 patients with and without HF. Methods Patients (n = 437) consecutively admitted with COVID-19 were categorized according to the presence vs. absence of HF and subcategorized according to HFpEF and HFrEF (EF 0.05) and there were no differences in inflammatory markers (ferritin, D-dimer, CRP, LDH). Independent predictors of inpatient mortality included: HFpEF (adjOR 2.55 (1.37-4.76)), age > 65 years (adjOR 3.00 (1.66-5.43), African American race (adjOR 1.82 (1.00-3.30)), Other race (adjOR 2.34 (1.02-5.37), p = 0.043), cerebrovascular disease (adjOR 3.07 (1.54-6.10), p = 0.001), and chronic hypoxic respiratory failure [adjOR 3.02 (1.19-7.62], p = 0.019)], whereas HFrEF was not (adjOR 1.58 (0.77-3.23). Discussion HF is prevalent in patients admitted with COVID-19. Patients with HFpEF had 2.6-fold higher mortality than those without HF and greater burdens of inpatient complications. Patients with HFpEF with COVID19 may warrant closer outpatient monitoring and a lower threshold for admission.
