Aims: The fatalities case due to coronavirus disease 2019 (COVID-19) is escalating. However, information on critical complications in hospitalized patients of COVID-19 is scant. We aimed to explore the prevalence of acute cardiac injury and its association with in-hospital mortality in COVID-19 patients. Methods: This retrospective study analyzed COVID-19 patients in Union Hospital (Wuhan, China) from Jan 24 to March 18, 2020. Clinical outcomes (discharge, or death) were monitored to April 9, 2020, the latest date of follow-up. Demographic, clinical, laboratory, echocardiographic data, treatment and prognosis were analyzed. Results: A total of 235 COVID-19 patients were included in the final analysis. Their median age was 66 years (interquartile range 57 - 73), and 131 (55.7%) were men. 98 (41.7%) patients were diagnosed with acute cardiac injury, of whom 60 (61.2%) died. There were more comorbidities in those who with acute cardiac injury than those without. A higher proportion of patients with acute cardiac injury received glucocorticoid therapy (68.0% vs 37.0%; P < 0.001), immunoglobulin (53.1% vs 30.1%; P < 0.001) and invasive mechanical ventilation (40.8% vs 6.6%; P < 0.001) than those without. The percentage of patients who were admitted to intensive care unit (39.8 % vs 8.0%; P < 0.001) or died during hospitalization (61.2% vs 8.0%, P < 0.001) were also higher in those with acute cardiac injury. Plasma high-sensitivity troponin I level correlated significantly with plasma interleukin -6, procalcitonin and C-reactive protein levels in COVID-19 patients. Echocardiography showed that cardiac function was attenuated in acute cardiac injury patients. Multivariable Cox proportional hazards regression analysis showed acute cardiac injury was an independent risk factor for higher in-hospital mortality in COVID-19 patients (HR, 3.393; 95% CI, 1.647- 6.987, P <0.001). Conclusions: Acute cardiac injury is a common condition and may be related to inflammatory response in COVID-19 patients. In addition, our study highlights an association between acute cardiac injury and a higher risk of in-hospital mortality. It is suggested that clinicians should be alert to acute cardiac injury in COVID-19 patients and take prompt treatments to improve outcomes.

Background: The number of fatalities due to coronavirus disease 2019 (COVID-19) is escalating. However, information on critical complications in hospitalized patients of COVID-19 is scant. We aimed to explore the prevalence of acute cardiac injury and its association with in-hospital mortality in COVID-19 patients. Method: This retrospective study analyzed patients confirmed with COVID-19 in Union Hospital (Wuhan, China) from Jan 24 to March 18, 2020. Clinical outcomes (discharge, or death) were monitored to April 9, 2020, the latest date of follow-up. Demographic, clinical, laboratory, echocardiographic data as well as treatment and prognosis were analyzed. Comparisons were made between patients with acute cardiac injury and those without. An association of acute cardiac injury and in-hospital mortality was identified. Results: A total of 235 COVID-19 patients were included in the final analysis. Their median age was 66 years (interquartile range 57 - 73 years), and 131 (55.7%) were men. 98 (41.7%) patients were diagnosed with acute cardiac injury, of whom 60 (61.2%) died. There were more comorbidities in those who had acute cardiac injury than those who did not have. A higher proportion of patients with acute cardiac injury received glucocorticoid therapy (68.0% vs 37.0%; P < 0.001), immunoglobulin (53.1% vs 30.1%; P < 0.001), high-flow oxygen (79.6% vs 43.1%; P < 0.001), and invasive mechanical ventilation (40.8% vs 6.6%; P < 0.001) than those without acute cardiac injury. The percentage of patients who were admitted to intensive care unit (39.8 % vs 8.0%; P < 0.001) or died during hospitalization (61.2% vs 8.0%, P < 0.001) were also higher in those with acute cardiac injury.

Background and objectivesPrevious reports on the outbreak of coronavirus disease 2019 were on the basis of data from the general population. Our study aimed to investigate the clinical features of patients on maintenance hemodialysis.Design, setting, participants, & measurements In this retrospective, single-center study, we included 49 hospitalized patients on maintenance hemodialysis and 52 hospitalized patients without kidney failure (controls) with confirmed coronavirus disease 2019 at Tongren Hospital of Wuhan University from January 30, 2020 to March 10, 2020. Demographic, clinical, laboratory, and radiologic characteristics and treatment and outcomes data were analyzed. The final date of follow-up was March 19, 2020.ResultsThe median age of 101 patients was 62 years (interquartile range, 49–72). All patients were local residents of Wuhan. In terms of common symptoms, there were differences between patients on hemodialysis and controls (fatigue [59% versus 83%], dry cough [49% versus 71%], and fever [47% versus 90%]). Lymphocyte counts were decreased (0.8×109/L [patients on hemodialysis] versus 0.9×109/L [controls], P=0.02). Comparing patients on hemodialysis with controls, creatine kinase–muscle and brain type, myoglobin, hypersensitive troponin I, B-type natriuretic peptide, and procalcitonin were increased, and the percentage of abnormalities in bilateral lung was higher in computed tomographic scan (82% versus 69%, P=0.15) and unilateral lung was lower (10% versus 27%, P=0.03). Common complications including shock, acute respiratory distress syndrome, arrhythmia, and acute cardiac injury in patients on hemodialysis were significantly higher. Compared with controls, more patients on hemodialysis received noninvasive ventilation (25% versus 6%, P=0.008). As of March 19, 2020, three patients on hemodialysis (6%) were transferred to the intensive care unit and received invasive ventilation. Seven patients on hemodialysis (14%) had died.ConclusionsThe main symptoms of coronavirus disease 2019 pneumonia, including fever and cough, were less common in patients on hemodialysis. Patients on hemodialysis with coronavirus disease 2019 were at higher risk of death.

Statin Use

Background There is an urgent need for novel therapeutic strategies for reversing COVID-19-related lung inflammation. Recent evidence has demonstrated that the cholesterol-lowering agents, statins, are associated with reduced mortality in patients with various respiratory infections. We sought to investigate the relationship between statin use and COVID-19 disease severity in hospitalized patients. Methods A retrospective analysis of COVID-19 patients admitted to the Johns Hopkins Medical Institutions between March 1, 2020 and June 30, 2020 was performed. The outcomes of interest were mortality and severe COVID-19 infection, as defined by prolonged hospital stay (≥ 7 days) and/ or invasive mechanical ventilation. Logistic regression, Cox proportional hazards regression and propensity score matching were used to obtain both univariable and multivariable associations between covariates and outcomes in addition to the average treatment effect of statin use. Results Of the 4,447 patients who met our inclusion criteria, 594 (13.4%) patients were exposed to statins on admission, of which 340 (57.2%) were male. The mean age was higher in statin users compared to non-users [64.9 ± 13.4 vs. 45.5 ± 16.6 years, p <0.001]. The average treatment effect of statin use on COVID-19-related mortality was RR = 1.00 (95% CI: 0.99–1.01, p = 0.928), while its effect on severe COVID-19 infection was RR = 1.18 (95% CI: 1.11–1.27, p <0.001). Conclusion Statin use was not associated with altered mortality, but with an 18% increased risk of severe COVID-19 infection.

Abstract Backgrounds Patients at greatest risk of severe clinical conditions from coronavirus disease 2019 (COVID-19) and death are elderly and comorbid patients. Increased levels of cardiac troponins identify patients with poor outcome. The present study aimed to describe the clinical characteristics and outcomes of a cohort of Italian inpatients, admitted to a medical COVID-19 Unit, and to investigate the relative role of cardiac injury on in-hospital mortality. Methods and results We analyzed all consecutive patients with laboratory-confirmed COVID-19 referred to our dedicated medical Unit between February 26th and March 31st 2020. Patients’ clinical data including comorbidities, laboratory values, and outcomes were collected. Predictors of in-hospital mortality were investigated. A mediation analysis was performed to identify the potential mediators in the relationship between cardiac injury and mortality. A total of 109 COVID-19 inpatients (female 36%, median age 71 years) were included. During in-hospital stay, 20 patients (18%) died and, compared with survivors, these patients were older, had more comorbidities defined by Charlson comorbidity index ≥ 3(65% vs 24%, p = 0.001), and higher levels of high-sensitivity cardiac troponin I (Hs-cTnI), both at first evaluation and peak levels. A dose–response curve between Hs-cTnI and in-hospital mortality risk up to 200 ng/L was detected. Hs-cTnI, chronic kidney disease, and chronic coronary artery disease mediated most of the risk of in-hospital death, with Hs-cTnI mediating 25% of such effect. Smaller effects were observed for age, lactic dehydrogenase, and d-dimer. Conclusions In this cohort of elderly and comorbid COVID-19 patients, elevated Hs-cTnI levels were the most important and independent mediators of in-hospital mortality.

Abstract Aims  The incidence and outcomes of a requirement for non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV) in acute heart failure (AHF) hospitalization are not clearly established. Thus, we aimed to characterize the incidence and trends in use of IMV and NIV in AHF and to estimate the magnitude of hazard for mortality associated with requiring IMV and NIV in AHF. Methods and results  We used the National Inpatient Sample (NIS) to identify AHF hospitalizations between 2008 and 2014. The exposure variable of interest was IMV or NIV use within 24 h of hospital admission compared to no respiratory support. We analysed the association between ventilation strategies and in-hospital mortality using Cox proportional hazards models adjusting for demographics and comorbidities. We included 6 534 675 hospitalizations for AHF. Of these, 271 589 (4.16%) included NIV and 51 459 (0.79%) included IMV within the first 24 h of hospitalization and rates of NIV and IMV use increased over time. In-hospital mortality for AHF hospitalizations including NIV was 5.0% and 27% for IMV compared with 2.1% for neither (P < 0.001 for both). In an adjusted model, requirement for NIV was associated with over two-fold higher risk for in-hospital mortality [hazard ratio (HR) 2.10, 95% confidence interval (CI) 2.01–2.19; P < 0.001] and requirement for IMV was associated with over three-fold higher risk for in-hospital mortality (HR 3.39, 95% CI 3.14–3.66; P < 0.001). Conclusion  Respiratory support is used in many AHF hospitalizations, and AHF patients who require respiratory support are at high risk for in-hospital mortality. Our work should inform prospective intervention trials and quality improvement ventures in this high-risk population.

AbstractBackgroundSince December 2019, a cluster of coronavirus disease 2019 (COVID-19) occurred in Wuhan, Hubei Province, China and spread rapidly from China to other countries. In-hospital mortality are high in severe cases and cardiac injury characterized by elevated cardiac troponin are common among them. The mechanism of cardiac injury and the relationship between cardiac injury and in-hospital mortality remained unclear. Studies focused on cardiac injury in COVID-19 patients are scarce.ObjectivesTo investigate the association between cardiac injury and in-hospital mortality of patients with confirmed or suspected COVID-19.MethodsDemographic, clinical, treatment, and laboratory data of consecutive confirmed or suspected COVID-19 patients admitted in Wuhan No.1 Hospital from 25th December, 2019 to 15th February, 2020 were extracted from electronic medical records and were retrospectively reviewed and analyzed. Univariate and multivariate Cox regression analysis were used to explore the risk factors associated with in-hospital death.ResultsA total of 110 patients with confirmed (n=80) or suspected (n=30) COVID-19 were screened and 48 patients (female 31.3%, mean age 70.58±13.38 year old) among them with high-sensitivity cardiac troponin I (hs-cTnI) test within 48 hours after admission were included, of whom 17 (17/48, 35.4%) died in hospital while 31 (31/48, 64.6%) were discharged or transferred to other hospital. High-sensitivity cardiac troponin I was elevated in 13 (13/48, 27.1%) patents. Multivariate Cox regression analysis showed pulse oximetry of oxygen saturation (SpO2) on admission (HR 0.704, 95% CI 0.546-0.909, per 1% decrease, p=0.007), elevated hs-cTnI (HR 10.902, 95% 1.279-92.927, p=0.029) and elevated d-dimer (HR 1.103, 95%CI 1.034-1.176, per 1mg/L increase, p=0.003) on admission were independently associated with in-hospital mortality.ConclusionsCardiac injury defined by hs-cTnI elevation and elevated d-dimer on admission were risk factors for in-hospital death, while higher SpO2 could be seen as a protective factor, which could help clinicians to identify patients with adverse outcome at the early stage of COVID-19.

AbstractErector spinae muscle (ESM) size has been reported as a predictor of prognosis in patients with some respiratory diseases. This study aimed to assess the association of ESM size on all-cause in-hospital mortality among elderly patients with pneumonia. We retrospectively included patients (age: ≥ 65 years) admitted to hospital from January 2015 to December 2017 for community-acquired pneumonia who underwent chest computed tomography (CT) on admission. The cross-sectional area of the ESM (ESMcsa) was measured on a single-slice CT image at the end of the 12th thoracic vertebra and adjusted by body surface area (BSA). Cox proportional hazards regression models were used to assess the influence of ESMcsa/BSA on in-hospital mortality. Among 736 patients who were admitted for pneumonia, 702 patients (95%) underwent chest CT. Of those, 689 patients (98%) for whom height and weight were measured to calculate BSA were included in this study. Patients in the non-survivor group were significantly older, had a greater frequency of respiratory failure, loss of consciousness, lower body mass index, hemoglobin, albumin, and ESMcsa/BSA. Multivariate analysis showed that a lower ESMcsa/BSA independently predicted in-hospital mortality after adjusting for these variables. In elderly patients with pneumonia, quantification of ESMcsa/BSA may be associated with in-hospital mortality.

Introduction While there are rigourous assessments made of trainees’ knowledge through formal examinations, objective assessments of technical skills are not available. Little is known about the safety of allowing resident trainees to perform cardiac surgical operations. Methods Peri-operative date was prospectively collected on all patients who underwent coronary artery bypass grafting (CABG), aortic valve replacement (AVR) or a combined procedure between 1998 and 2005. Teaching-cases were identified by resident records and defined as cases which the resident performed skin to skin. Pre-operative characteristics were compared between teaching and non-teaching cases. Short-term adverse events were defined as a composite of: in-hospital mortality, stroke, intra- or post-operative intra-aortic balloon pump (IABP) insertion, myocardial infarction, renal failure, wound infection, sepsis or return to the operating room. Intermediate adverse outcomes were defined as hospital readmission for any cardiac disease or late mortality. Logistic regression and Cox proportional hazard models were used to adjust for differences in age, acuity, and medical co-morbidities. Outcomes were compared between teaching and non-teaching cases. Results 6929 cases were included, 895 of which were identified as teaching-cases. Teaching-cases were more likely to have an EF<40%, pre-operative IABP, CHF, combined CABG/AVRs or total arterial grafting cases (all p<0.01). However, a case being a teaching-case was not a predictor of in-hospital mortality (OR=1.02, 95%CI 0.67–1.55) or the composite short-term outcome (OR=0.97, 95%CI 0.75–1.24). The Kaplan-Meier event-free survival of staff and teaching-cases was equivalent at 1, 3, and 5 years: 80% vs. 78%, 67% vs. 66%, and 58% vs. 55% (log-rank p=0.06). Cox proportional hazards regression modeling did not demonstrate teaching-case to be a predictor of late death or re-hospitalization (HR=1.05, 95%CI 0.94 –1.18). Conclusions Teaching-cases were more likely to have greater acuity and complexity than non-teaching cases. Despite this, teaching cases did no worse than staff cases in the short or intermediate term. Allowing residents to perform cardiac surgery does not appear to adversely affect patient outcomes.

Introduction: Unplanned hospitalizations are commonly associated with a circulating troponin concentration >99 th percentile upper reference limit (URL). In order to better understand the clinical significance of troponin elevation, we evaluated outcomes in hospitalized patients according to cardiac endotype. Methods: We prospectively screened consecutive hospitalized patients with elevated high-sensitivity troponin-I (hs-TnI) concentrations (Abbott ARCHITECT troponin-I assay; sex-specific URL, 99 th centile: male: >34ng/L; female: >16ng/L) within a regional cardiac care network (population 650,000). A cardiology clinical team adjudicated individual patient records and assigned endotypes by consensus agreement according to the Fourth Universal Definition of Myocardial Infarction (MI). Endotypes were sub-classified into etiological category by inciting event(s). Characteristics and comorbidity were compared and outcomes recorded on virtual follow-up until June 2 nd 2020. Results: A total of 390 consecutive patients with ≥1 hs-TnI value >URL between March 1-April 15, 2020, were evaluated; 44 patients were excluded ( Duplicates: 2; Missing data: 41; Research patient: 1 ). Of 346 who qualified for inclusion, an index diagnosis of Type 1 MI (T1MI), T2MI and myocardial injury were assigned in 115 (33.2%), 79 (22.8%) and 152 (43.9%) patients, respectively. Compared with T1MI, patients with T2MI and myocardial injury had lower peak hs-TnI values (median [IQR]: 86 [250-697] vs 5020 [853-7774]ng/L; p< 0.01), lower estimated 10-year survival (40.2% vs 53.4%; p=0.002), less frequently underwent coronary revascularization (1.4% vs 45.2%; p<0.0005) and had longer inpatient stay (13.0 vs 6.1 days). Inpatient and overall mortality rates from admission to follow-up (median [range]: 71 [0-151] days) were higher among patients with T2MI and myocardial injury (19.9% vs 7.8%; p=0.004; and 26.0% vs 11.3%; Log rank (Mantel-Cox) X 2 = 1.927; p=0.003) independent of similar cardiovascular risk profiles. Conclusions: Despite lower peak circulating troponin concentrations, patients with T2MI and myocardial injury had higher inpatient mortality, lower estimated 10-year survival and longer in-hospital stay compared to those with T1MI.

Abstract Background There is overwhelming volume of confirmed cases of COVID-19, despite this numerous knowledge gaps remain in the diagnosis, management, and prognostication of this novel coronavirus infection, making prevention and control a challenge. Methods This retrospective cohort study included patients with real-time reverse transcriptase polymerase chain reaction (rRT-PCR)-confirmed COVID-19. Binary logistic regression was used to determine the association between the cardiac biomarkers and in-hospital mortality. ROC, AUC, and cutoff analyses were used to determine optimal cutoff values for the cardiac biomarkers. Results A total of 90 subjects with a complete panel of cardiac biomarkers out of the 224 rRT-PCR confirmed cases were included. The median age was 57 years (IQR, 47–67 years), majority were males. Sixty-six (77.6%) subjects survived while 19 (22.4%) expired. The most common presenting symptom was fever (75.6%), and the most common comorbidity was hypertension (67.8%). Spearman rho correlation analysis showed moderate positive association of high sensitivity troponin I (hsTnI) with in-hospital mortality (R, 0.434, p = &lt;0.001). Multivariate binary logistic regression analysis showed that creatine kinase and hsTnI were independently associated with in-hospital mortality (OR, 4.103 [95% CI, 1.241–13.563], p=0.021; and OR, 7.899 [95% CI, 2.430–25.675], p=0.001, respectively). ROC curve analysis showed that hsTnI was a good predictor for in-hospital mortality (AUC, 0.829 [95% CI, 0.735–0.923], p = &lt;0.001) and that creatine kinase was a poor predictor (AUC, 0.677 [95% CI, 0.531–0.823], p=0.018). Optimal cutoff point derived from the ROC curve for hsTnI was 0.010 ng/ml (J, 0.574) with a sensitivity of 84% (TPR, 0.842 [95% CI, 0.604–0.966]), specificity of 73% (TNR, 0.732 [95% CI, 0.614–0.386]), and an adjusted negative predictive value of 99% (Known prevalence*adjusted NPV, 0.989), a positive likelihood ratio of 20% (LR+, 3.147 [95% CI, 2.044–4.844]) and a negative likelihood ratio of 30% (LR−, 0.216 [95% CI, 0.076–0.615]). Conclusion High sensitivity troponin I level was a good tool with a very high negative predictive value in significantly predicting in-hospital mortality among rRT-PCR positive COVID-19 patients.
