Noninvasive Physiologic Assessment of Cardiac Allograft Vasculopathy Is Prognostic for Post-Transplant Events.

BACKGROUND: Cardiac allograft vasculopathy (CAV) causes impaired blood flow in both epicardial coronary arteries and the microvasculature. A leading cause of post-transplant mortality, CAV affects 50% of heart transplant recipients within 10 years of heart transplant. OBJECTIVES: This analysis examined the outcomes of heart transplant recipients with reduced myocardial blood flow reserve (MBFR) and microvascular CAV detected by 13N-ammonia positron emission tomography (PET) myocardial perfusion imaging. METHODS: A total of 181 heart transplant recipients who underwent PET to assess for CAV were included with a median follow-up of 4.7 years. Patients were classified into 2 groups according to the total MBFR: >2.0 and ≤2.0. Microvascular CAV was defined as no epicardial CAV detected by PET and/or coronary angiography, but with an MBFR ≤2.0 by PET. RESULTS: In total, 71 (39%) patients had an MBFR ≤2.0. Patients with an MBFR ≤2.0 experienced an increased risk for all outcomes: 7-fold increase in death or retransplantation (HR: 7.05; 95% CI: 3.2-15.6; P < 0.0001), 12-fold increase in cardiovascular death (HR: 12.0; 95% CI: 2.64-54.12; P = 0.001), and 10-fold increase in cardiovascular hospitalization (HR: 10.1; 95% CI: 3.43-29.9; P < 0.0001). The 5-year mean survival was 302 days less than those with an MBFR >2.0 (95% CI: 260.2-345.4 days; P < 0.0001). Microvascular CAV (adjusted HR: 3.86; 95% CI: 1.58-9.40; P = 0.003) was independently associated with an increased risk of death or retransplantation. CONCLUSIONS: Abnormal myocardial blood flow reserve, even in the absence of epicardial CAV, identifies patients at a high risk of death or retransplantation. Measures of myocardial blood flow provide prognostic information in addition to traditional CAV assessment.

Myocardial injury after major non-cardiac surgery evaluated with advanced cardiac imaging: a pilot study.

BACKGROUND: Myocardial injury after non-cardiac surgery (MINS) is a frequent complication caused by cardiac and non-cardiac pathophysiological mechanisms, but often it is subclinical. MINS is associated with increased morbidity and mortality, justifying the need to its diagnose and the investigation of their causes for its potential prevention. METHODS: Prospective, observational, pilot study, aiming to detect MINS, its relationship with silent coronary artery disease and its effect on future adverse outcomes in patients undergoing major non-cardiac surgery and without postoperative signs or symptoms of myocardial ischemia. MINS was defined by a high-sensitive cardiac troponin T (hs-cTnT) concentration > 14 ng/L at 48-72 h after surgery and exceeding by 50% the preoperative value; controls were the operated patients without MINS. Within 1-month after discharge, cardiac computed tomography angiography (CCTA) and magnetic resonance imaging (MRI) studies were performed in MINS and control subjects. Significant coronary artery disease (CAD) was defined by a CAD-RADS category ≥ 3. The primary outcomes were prevalence of CAD among MINS and controls and incidence of major cardiovascular events (MACE) at 1-year after surgery. Secondary outcomes were the incidence of individual MACE components and mortality. RESULTS: We included 52 MINS and 12 controls. The small number of included patients could be attributed to the study design complexity and the dates of later follow-ups (amid COVID-19 waves). Significant CAD by CCTA was equally found in 20 MINS and controls (30% vs 33%, respectively). Ischemic patterns (n = 5) and ischemic segments (n = 2) depicted by cardiac MRI were only observed in patients with MINS. One-year MACE were also only observed in MINS patients (15.4%). CONCLUSION: This study with advanced imaging methods found a similar CAD frequency in MINS and control patients, but that cardiac ischemic findings by MRI and worse prognosis were only observed in MINS patients. Our results, obtained in a pilot study, suggest the need of further, extended studies that screened systematically MINS and evaluated its relationship with cardiac ischemia and poor outcomes. Trial registration Clinicaltrials.gov identifier: NCT03438448 (19/02/2018).

Lung Transplantation for COVID-19 Pulmonary Sequelae.

BACKGROUND: The role of lung transplantation for coronavirus disease 2019 (COVID-19)-related lung failure is evolving as the pandemic persists. METHODS: From January 2021 to April 2022, 20 patients (median age 62 y; range 31-77) underwent lung transplantation for COVID-related lung failure at our institution. We reviewed their clinical and intraoperative characteristics and early outcomes including postoperative complications. RESULTS: Eleven patients (55%) had chronic lung disease when they contracted COVID-19. All 20 patients required hospitalization for antivirus treatment. Median lung allocation score was 74.7 (33.1-94.0). Thirteen patients (65%) underwent single-lung transplants, and 7 patients (35%) underwent double-lung transplants. Concomitant coronary artery bypass graft surgery was performed in 2 (10%) patients because of severe coronary artery disease. Postoperatively, venovenous extracorporeal membrane oxygenation was needed in 3 patients (15%) because of severe primary graft dysfunction; all were eventually weaned. Ten patients (50%) experienced deep venous thrombosis, and 1 eventually developed a major pulmonary embolus. The median intensive care unit stay and hospital stays were 6.5 d (3-44) and 18 d (7-77), respectively. During a median follow-up of 201 d (47-418), we experienced 1 late mortality due to COVID-19-related myocarditis. Among the 13 patients with single-lung transplant, 5 demonstrated improvement in their native lungs. CONCLUSIONS: Lung transplantation yielded favorable early outcomes in a heterogeneous patient cohort that included older patients, obese patients, and patients with coronary artery disease or preexisting chronic lung disease. Our data also shed light on the transforming role of lung transplantation for the pulmonary sequelae of a complex multisystem COVID-19 disorder.

Common coronary artery occlusions in patients with myocardial infarction.

Introduction: coronary artery disease (CAD) is a significant cardiovascular disease (CVD) that affects people worldwide. This study aimed to determine the main occluded coronary arteries in patients with myocardial infarction in Najran, Kingdom of Saudi Arabia (KSA). Methods: a retrospective cross-sectional study conducted between March 2020 and March 2021 and involving 661 myocardial infarction patients recruited from two hospitals (King Khalid Hospital and Prince Sultan Centre for Healthcare in Najran) used sampling for enrolled patients. Patients over the age of 15 years, current residents of KSA, and diagnosed with coronary artery occlusion based on at least one identifiable coronary lesion on a coronary angiography were considered eligible. We created generalized linear mixed models to investigate patients´ clinical and coronary angiographic features and identify statistically relevant components. Results: there were 661 CAD cases in this study: 548 (82.9%) males and 113 (17.1%) females, with a mean and standard deviation (SD) age of 4.03 ± 1.370 years. Ages of the 661 participants ranged from 15 to 85, who had been diagnosed with myocardial infarction were evaluated. It was found that most of the patients were in the 55-64 age range. The majority of cases (366 (55.4%) had ST-segment elevation myocardial infarction (STEMI), 187 (28.3%) had non-ST-segment elevation (NSTEMI), 101 (15.3%) had acute coronary syndrome-non-ST-segment elevation (ACS-NSTEMI), and 7 (1.1%) had acute coronary syndrome-ST-segment elevation (ACS-STEMI). Conclusion: the left anterior descending artery (LAD) is the commonest lesion found in both ST-segment elevation and non-ST-segment elevation myocardial infarction patients.

The impact of the Coronavirus disease 2019 on hospitalizations for coronary artery revascularization: results from California State Inpatient Database.

BACKGROUND: Coronavirus disease 2019 (COVID-19) outbreak has negatively impacted routine cardiovascular care. In this study, we assessed the impact of COVID-19 pandemic on percutaneous coronary artery intervention (PCI) and coronary artery bypass grafting (CABG) hospitalizations and outcomes using a large database. METHODS: The current study was a retrospective analysis of California State Inpatient Database (SID) during March-December of 2019 and 2020. All adult hospitalizations for coronary artery revascularization were included for the analysis. ICD-10-CM diagnosis and procedure codes were used for identifying hospitalizations and procedures. The primary outcome was inhospital mortality, and secondary outcomes were hospital length of stay, stroke, acute kidney injury, and mechanical ventilation. Propensity score match analysis was done to compare adverse clinical outcomes. RESULTS: PCI hospitalizations (relative decrease, 15.0%, P for trend <0.001) and CABG hospitalizations (relative decrease, 16.4%, P for trend <0.001) decreased from 2019 to 2020, while viral pneumonia hospitalizations increased (relative increase, 1751.6%, P for trend <0.001). Monthly PCI and CABG hospitalization showed decreasing trends from January 2019 to December 2020. Propensity score match analysis showed that the odds of inhospital mortality (OR, 1.12; 95% CI, 1.01-1.24), acute kidney injury (OR, 1.12; 95% CI, 1.06-1.17), and ARDS (OR, 1.89; 95% CI, 1.18-3.01) were higher among patients who received PCI in 2020. CONCLUSION: Results of our study indicate that initiatives such as encouraging patients to receive treatments and controlling the spread of COVID-19 should be instituted to improve PCI and CABG hospitalizations.

The relationship between the severity of coronary artery disease in angiography and the incidence of short-term major cardiovascular events of patients with Covid-19 and myocardial infarction: a cross-sectional study in Iran (preprint)

Background Coronary artery disease (CAD) has been frequently recognized as a risk factor for poor prognosis in COVID-19 patients. Syntax score is an invasive coronary angiographic-based tool used to determine the severity of CAD. In this study, we aim to investigate the prognostic significance of syntax score for mortality and morbidity among COVID-19 patients.Methods In this cross-sectional study, we have included patients with confirmed COVID-19 diagnosis who underwent percutaneous coronary intervention (PCI). Based on angiographic records, the CAD complexity was measured by Syntax score, and echocardiographic variables were documented. The laboratory data were obtained from the HISS database of the hospital. All patients were followed up one month after discharge for new cardiovascular events, rehospitalization, heart failure (HF), stent thrombosis, cerebrovascular accidents, and death.Results In one month, 108 patients were included in the study. The mean age was 64.8 ± 11.6, and 74% were male. The Cox regression model found no association between the Syntax score and the composite outcomes. In the univariate cox proportional HR model, MPV, LDH, and ESR were found to have predictive significance for in-hospital death. AKI was resulted to be significantly associated with rehospitalization in multivariate analysis.Conclusion The present study did not find a significant association between adverse outcomes and syntax score in COVID-19 patients referred for PCI. Acute kidney injury and duration of ICU stay was found to be the main factor predicting rehospitalization and HF. Future studies are needed to confirm these findings.

The Utility of Home Sleep Apnea Testing in the Advanced Heart Failure Populations.

Untreated sleep disorders form a risk of coronary artery disease, hypertension, obesity, and diabetes mellitus. Access to polysomnography is limited, especially during the COVID-19 pandemic, with home sleep apnea testing (HSAT) being a potentially viable alternative. We describe an HSAT protocol in patients with advanced heart failure (HF). In a single-center, observational analysis between 2019 and 2021 in patients with advanced HF and heart transplant (HT), 135 screened positive on the STOP-Bang sleep survey and underwent a validated HSAT (WatchPAT, ZOLL-Itamar). HSAT was successful in 123 patients (97.6%), of whom 112 (91.1%; 84 HF and 28 HT) tested positive for sleep apnea. A total of 91% of sleep apnea cases were obstructive, and 63% were moderate to severe. Multivariable linear regression showed that the apnea hypopnea index was 34% lower in the HT group than in the HF group (p = 0.046) after adjusting for gender, and that this effect persisted in White patients but not among African-Americans. Patient characteristics were similar between groups, with coronary artery disease, diabetes mellitus, and hypertension as the most prevalent co-morbidities. In conclusion, sleep apnea remains prevalent in patients with HF with a high co-morbidity burden. HSAT is a feasible and effective tool for screening and diagnosis in this population.

Fear of COVID-19 and social distancing on the health behavior of coronary heart disease patients.

PURPOSE: This study aimed to provide basic data to improve the health behavior of patients diagnosed with coronary artery disease during pandemics such as that caused by coronavirus disease 2019 (COVID-19) by identifying the fear of COVID-19 and the degree of social distancing behavior of coronary patients. METHODS: In this study, 162 patients diagnosed with coronary artery disease who received follow-up care at the cardiovascular center of Dong-A University Hospital in Busan were selected. The variables examined in this study included subjects' general characteristics and disease-related characteristics, fear of COVID 19, social distancing behavior, and health behavior. Data were collected from June 8-25, 2021, and data analysis was performed using the IBM SPSS26.0 program. RESULTS: The results showed that older participants, those who were religious, those with cohabitants, and those who showed better compliance with social distancing showed better health behavior practice. Factor with the greatest influence on the health behavior of patients with coronary artery disease was social distancing behavior (ß = 0.299, p < .001). CONCLUSION: After the COVID-19 pandemic, it is necessary to develop a health care program to promote the health behavior of high-risk patients, including coronary artery disease, in preparation for the COVID-19 era. The younger the patient, the fewer health activities are undertaken when living alone, so appropriate education and support for these individuals should increase the rate of implementation of health activities for coronary artery disease.

Multisystem inflammatory syndrome in children associated with SARS-CoV-2 infection and severe abdominal syndrome: the Lviv "OHMATDYT" (Western Ukraine) experience.

Multisystem inflammatory syndrome in children (MIS-C) associated with Severe Acute Respiratory Coronavirus 2 (SARS-CoV-2) usually develops 1-1.5 months after mild or asymptomatic COVID-19 in countries with high incidence. MIS-C has a polymorphism of clinical manifestations, which include prolonged fever, polymorphic rash, non-purulent conjunctivitis, pneumonia complicated by distress syndrome, myocarditis, coronary artery disease, toxic shock syndrome, limb edema, polyserositis, severe abdominal syndrome with diarrhea and others. Establishing this diagnosis requires significant efforts to rule out diseases of other etiology. The aim of our study was to analyze the clinical and laboratory features of children with MIS-C associated with SARS-CoV-2 and severe abdominal syndrome. Six children with MIS-C associated with SARS-CoV-2 and severe abdominal syndrome were hospitalized in Lviv Regional Children's Clinical Hospital "OHMATDYT", Ukraine, from April 2020 to September 2021. For differential diagnosis IgM, IgG to SARS-CoV-2 by ELISA, RNA to SARS-CoV-2 by PCR, bacteriological tests of blood, urine and feces were performed. Furthermore, the diagnostic work up included chest radiography, echocardiography, ultrasound of the lungs and abdominal organs. Laboratory findings revealed an increase in the normal value of inflammatory markers and high levels of IgG to SARS-CoV-2. Administration of intravenous immunoglobulin at a dose of 1 to 2 g/kg body weight per day prevented further coronary artery disease in patients and provided regression in already affected coronary arteries. At the same time, regression of abdominal syndrome was observed. Early diagnosis of MIS-C in patients with SARS-CoV-2 and severe abdominal syndrome allows to define the appropriate treatment strategy.

Elucidating the genetic architecture of DNA methylation to identify promising molecular mechanisms of disease.

DNA methylation commonly occurs at cytosine-phosphate-guanine sites (CpGs) that can serve as biomarkers for many diseases. We analyzed whole genome sequencing data to identify DNA methylation quantitative trait loci (mQTLs) in 4126 Framingham Heart Study participants. Our mQTL mapping identified 94,362,817 cis-mQTLvariant-CpG pairs (for 210,156 unique autosomal CpGs) at P < 1e-7 and 33,572,145 trans-mQTL variant-CpG pairs (for 213,606 unique autosomal CpGs) at P < 1e-14. Using cis-mQTL variants for 1258 CpGs associated with seven cardiovascular disease (CVD) risk factors, we found 104 unique CpGs that colocalized with at least one CVD trait. For example, cg11554650 (PPP1R18) colocalized with type 2 diabetes, and was driven by a single nucleotide polymorphism (rs2516396). We performed Mendelian randomization (MR) analysis and demonstrated 58 putatively causal relations of CVD risk factor-associated CpGs to one or more risk factors (e.g., cg05337441 [APOB] with LDL; MR P = 1.2e-99, and 17 causal associations with coronary artery disease (e.g. cg08129017 [SREBF1] with coronary artery disease; MR P = 5e-13). We also showed that three CpGs, e.g., cg14893161 (PM20D1), are putatively causally associated with COVID-19 severity. To assist in future analyses of the role of DNA methylation in disease pathogenesis, we have posted a comprehensive summary data set in the National Heart, Lung, and Blood Institute's BioData Catalyst.

Safety and efficacy of percutaneous coronary intervention combined with catheter ablation in a single procedure for patients with coronary artery disease complicated with atrial fibrillation (preprint)

Background Coronary artery disease (CAD) always co-exists with atrial fibrillation (AF). A new delivery of cardiac interventions for patients is needed during or even after the 2019 coronavirus disease (COVID-19) pandemic. This study aimed to evaluate the safety and efficacy of percutaneous coronary interventions (PCI) combined with AF catheter ablation (AFCA) in a single procedure for patients with CAD and AF.Methods From Jan 2020 to Jun 2021, 40 consecutive patients who underwent both PCI and AFCA were retrospectively enrolled for this study. All patients were followed up 1, 3, 6, and 12 months after the procedure. The primary safety outcomes included cardiac tamponade, cerebrovascular accident/stroke, transient ischemic attack (TIA), thromboembolism, myocardial infarction, vascular access site complications, and bleeding. The primary efficacy outcomes included 12-month AF recurrence and in-stent restenosis (ISR).Results Six adverse events were reported, including small hematoma at the groin access site in two cases, minor bleeding in three cases, and stroke not related to the procedure in one case. No ISR was reported. The Kaplan-Meier analysis estimated that the AF-free success rate at 12 months was 95.7% in paroxysmal atrial fibrillation (PAF) patients and 64.7% in those with persistent atrial fibrillation (PsAF).Conclusions The combination of PCI and AFCA in one procedure was feasible, safe, and efficacious in patients with CAD and AF. The combined procedure can be recommended in clinical practice, during or even after the COVID-19 era.

Prior SARS-CoV-2 Infection Is Associated With Coronary Vasomotor Dysfunction as Assessed by Coronary Flow Reserve From Cardiac Positron Emission Tomography.

Background Cardiovascular complications from COVID-19 contribute to its high morbidity and mortality. The effect of COVID-19 infection on the coronary vasculature is not known. The objective of this study was to investigate the prevalence of coronary vasomotor dysfunction identified by coronary flow reserve from cardiac positron emission tomography in patients with previous COVID-19 infection. Methods and Results All patients who had polymerase chain reaction-confirmed SARS-CoV-2 infection referred for myocardial stress perfusion positron emission tomography imaging at Brigham and Women's Hospital from April 2020 to July 2021 were compared with a matched control group without prior SARS-CoV-2 infection imaged in the same period. The main outcome was the prevalence of coronary vasomotor dysfunction. Myocardial perfusion and myocardial blood flow reserve were quantified using N13-ammonia positron emission tomography imaging. Thirty-four patients with prior COVID-19 were identified and compared with 103 matched controls. The median time from polymerase chain reaction-confirmed SARS-CoV-2 to cardiac positron emission tomography was 4.6 months (interquartile range,1.2-5.6 months). There were 16 out of 34 (47%) patients previously hospitalized for COVID-19 infection. Baseline cardiac risk factors were common, and 18 (53%) patients in the COVID-19 group had abnormal myocardial perfusion. Myocardial blood flow reserve was abnormal (<2) in 44.0% of the patients with COVID-19 compared with 11.7% of matched controls (P<0.001). The mean myocardial blood flow reserve was 19.4% lower in patients with COVID-19 compared with control patients (2.00±0.45 versus 2.48±0.47, P<0.001). Conclusions Myocardial blood flow reserve was impaired in patients with prior COVID-19 infection compared with cardiovascular risk factor-matched controls, suggesting a relationship between SARS-CoV-2 infection and coronary vascular health. These data highlight the need to assess long-term consequences of COVID-19 on vascular health in future prospective studies.

Persistent Myocardial Dysfunction Assessed by Global Myocardial Strain in Covid-19 Recovered Patients with Cardiovascular Comorbidities at 3 Months after Acute Infection (preprint)

Background Previous studies reported the Coronavirus disease (COVID-19) has long implications, which involve multiple organs, including the cardiovascular system. This study aims to assess myocardial dysfunction by echocardiograph myocardial longitudinal strain Left ventricular-Global Longitudinal Strain (LV-GLS) and Right Ventricular-Free Wall Strain (RV-FWS) measurements as a marker for myocardial dysfunction and heart fibrosis. Additionally, we aim to identify admission factors that may serve as a predictor of long COVID syndrome.Methods This cross-sectional study assessed echocardiograph global longitudinal strain (GLS) values measurement done three months after initial hospitalization. Multivariate analysis was done to investigate admission factors associated with differences in GLS values.Results 100 subjects with cardiovascular comorbidities and prior COVID-19 infection were enrolled. Echocardiography examination showed lower GLS values in this group compared to the normal population. Demographic and risk factors-matched subjects without a history of COVID-19 (n = 31, Control 1) and healthy subjects (n-31, Control 2) were included as comparisons to validate GLS results. The case group had significantly lower LV-GLS values compared to other groups (p < 0.05, mean ± SD -16.17 ± 3.379, -19.48 ± 1.141, -21.48 ± 1.777 respectively for case, control one, and control two groups). Upon admission, a history of coronary artery disease was found to be associated with decreased LV GLS values in recovered COVID-19 patients with cardiovascular comorbidity.Conclusion LV GLS values significantly decreased in recovered COVID-19 patients with cardiovascular comorbidities. Upon admission, a history of CAD may predict cardiac long COVID-19 syndrome.

Older Adults' Attitudes Regarding COVID-19 and Associated Infection Control Measures in Shanghai, and Impact on Well-Being (preprint)

This cross-sectional study investigated health management, well-being, and pandemic-related perspectives in Shanghainese adults [≥]50 years during early and strict COVID-19 control measures. A self-report survey was administered via Wenjuanxing between March-April/2020. Items from the Somatic Symptom Scale, Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 were administered, as well as pandemic-specific questions. 1181 primarily married, retired females participated; Many had hypertension (n=521, 44.1%), coronary artery disease (CAD; n=201, 17.8%) and diabetes (n=171, 14.5%). While most respondents (n=868; 73.5%) were strictly following control measures (including limiting visits with children; n=390, 33.0%) and perceived they could tolerate that beyond 6 months (n=555;47.0%), they were optimistic about the future if control measures were continued (n=969;82.0%), and perceived impact would be temporary (n=646;64.7%). 52 of those with any condition (8.2%) and 19 of those without a condition (3.5%) reported the pandemic was impacting their health. Somatic symptoms were high (29.4+/-7.1/36), with Sleep & Cognitive symptoms highest. 24.4% and 18.9% of respondents had elevated depressive and anxious symptoms, respectively; greater distress was associated with lower income (p=0.018), having hypertension (p=0.001) and CAD (p<0.001), more negative perceptions of global COVID-19 control (p=0.004), COVID-19 spread (p[≤]0.001), impact on life and health (p<0.001), compliance with control measures (p<0.001), and shorter time control measures could be tolerated (p<0.001) in adjusted analyses. In the initial COVID-19 outbreak, most older adults were optimistic and resilient with regard to the epidemic and control measures. However, the distress of older adults is not trivial, particularly in those with health issues.

Contribution of genetics and lifestyle to the risk of major cardiovascular and thromboembolic complications following COVID-19 (preprint)

Clinical determinants for cardiovascular and thromboembolic (CVE) complications of COVID-19 are well-understood, but the roles of genetics and lifestyle remain unknown. We performed a prospective cohort study using UK Biobank, including 25,335 participants with confirmed SARS-CoV-2 infection between March 1, 2020, and September 3, 2021. Outcomes were hospital-diagnosed atrial fibrillation (AF), coronary artery disease (CAD), ischemic stroke (ISS), and venous thromboembolism (VTE) within 90 days post-infection. Heritable risk was represented by validated polygenic risk scores (PRSs). Lifestyle was defined by a composite of nine variables. We estimated adjusted hazard ratios (aHR) and confidence intervals (CI) using Cox proportional hazards models. In the COVID-19 acute phase, PRSs linearly predicted a higher risk of AF (aHR 1.52 per standard deviation increase, 95% CI 1.39 to 1.67), CAD (1.59, 1.40 to 1.81), and VTE (1.30, 1.11 to 1.53), but not ISS (0.92, 0.64 to 1.33). A healthy lifestyle was associated with a substantially lower risk of post-COVID-19 AF (0.70, 0.53 to 0.92), CAD (0.64, 0.44 to 0.91), and ISS (0.28, 0.12 to0.64), but not VTE (0.82, 0.48 to 1.39), compared with an unhealthy lifestyle. No evidence for interactions between genetics and lifestyle was found. Our results demonstrated that population genetics and lifestyle considerably influence cardiovascular complications following COVID-19, with implications for future personalised thromboprophylaxis and healthy lifestyle campaigns to offset the elevated cardiovascular disease burden imposed by the ongoing pandemic.

Long-term predictive value of cardiac biomarkers in patients with COVID-19 infection.

OBJECTIVE: Several studies have investigated the association between cardiac biomarkers and short-term prognosis in the COVID-19 infection. However, the data on the predictive value of cardiac biomarkers to predict long-term prognosis in COVID-19 infection are limited. We aimed at determining the relationship between N-terminal brain-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin I (hs-TnI) as cardiac biomarkers and in-hospital/long-term outcomes in COVID-19 infection. PATIENTS AND METHODS: The study included a total of 916 patients with confirmed COVID-19 infection. The primary outcome was in-hospital and 1-year mortality. The secondary outcome was intensive care need at admission or the need to be transferred to the intensive care unit later on. RESULTS: The study included 498 (54.4%) males and 418 (45.6%) females with a mean age of 55.1±18.5 years. The patients with known heart failure (HF), COVID-19-related HF, acute renal failure (ARF), chronic kidney disease (CKD), diabetes mellitus, hypertension, coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD)/asthma, high CO-RADS score (≥ 4), lower EF, higher hs-TnI, and NT-proBNP levels had increased in-hospital and 1-year mortality. After multivariate analysis, NT-proBNP, hs-TnI, CKD, ARF, diabetes mellitus, and CAD were independent predictors of in-hospital and 1-year mortality. After ROC analysis, NT-proBNP cut-off levels of 1022.50 (sensitivity 87.5%, specificity 87.1%) and 1008 (sensitivity 88.6%, specificity 88.0%) were found to predict in-hospital and 1-year mortality, respectively. Hs-TnI cut-off levels of 49.6 (sensitivity 88.6%, specificity 88.9%) and 34.10 (sensitivity 83.8%, specificity 84.1%) were found to predict in-hospital and 1-year mortality, respectively. CONCLUSIONS: The current study suggests that NT-proBNP and hs-TnI can be used as valuable cardiac biomarkers to predict short-term and long-term parameters in COVID-19 infection.

Reverse Takotsubo Cardiomyopathy After Casirivimab-Imdevimab Therapy in a Patient with COVID-19: A Case Report.

BACKGROUND Takotsubo cardiomyopathy, also referred to as apical ballooning syndrome (ABS), stress cardiomyopathy, or broken heart syndrome, initially described in Japan, is characterized by transient wall motion abnormalities involving the apical segment. Several variants have been described, including reverse type, mid-ventricular type, and the focal type. In the reverse type, there is basal hypokinesis and apical hyperkinesis. Stress cardiomyopathy is most likely to occur in middle-aged women and the underlying etiology is believed to be related to catecholamine release due to intense stress. CASE REPORT We report an extremely rare case of reverse takotsubo cardiomyopathy (rTTC) in a young woman with COVID-19 who was treated with Casirivimab-Imdevimab therapy. Our report is the second to reveal rTTC in a patient with COVID-19 in which obstructive coronary artery disease was definitively ruled out by coronary CT angiography. CONCLUSIONS Cardiovascular involvement in COVID-19 has been linked to increased morbidity and mortality rates. Recent reports have suggested the occasional occurrence of TTC and the rare occurrence of reverse takotsubo cardiomyopathy (rTTC) in patients with COVID-19. In fact, to the best of our knowledge, this is only the fifth reported case of rTTC in a patient with COVID-19; importantly, 3 out of the 4 of the previous reported cases lacked definitive ischemic work-up to rule out obstructive coronary artery disease due to the critical condition of the patients.

Impact of Omicron Wave and Associated Infection Prevention and Control Measures in Shanghai on Health Management and Psychosocial Well-Being of Patients with Chronic Conditions (preprint)

Background COVID-19 and associated controls may be particularly problematic in the context of chronic conditions. This study investigated health management, well-being, and pandemic-related perspectives in these patients in the context of stringent measures, and associated correlates. Methods A self-report survey was administered via Wenjuanxing in Simplified Chinese between March-June 2022 during the Omicron wave lockdown in Shanghai, China. Items from the Somatic Symptom Scale (SSS) and Symptom Checklist-90 (SCL-90) were administered, as well as pandemic-related items created by a working group of the Chinese Preventive Medical Association. Chronic disease patients in this cross-sectional study were recruited through an associated community family physician group. Results Overall, 1775 patients, mostly married females with hypertension, participated. Mean SSS scores were 36.1±10.5/80, with 41.5% scoring in the elevated range (i.e., above 36). In an adjusted model, female, diagnosis of coronary artery disease and arrhythmia, perceived impact of pandemic on life, duration can tolerate control measures, perception of future & control measures, impact of pandemic on health condition and change to exercise routine due to pandemic were significantly associated with greater distress. Approximately one-quarter (24.5%) perceived the pandemic had a permanent impact on their life, and 44.1% perceived at least a minor impact on their health. One-third (33.5%) discontinued exercise due to the pandemic. While 47.6% stocked up on their medications before the lockdown, their remaining supply was mostly only enough for a couple of weeks and 17.5% of participants discontinued use. Chief among their fears were inability to access healthcare (83.2%), and what they stated they most needed to manage their condition was medication access (65.6%). Conclusions Since 2020 when we assessed a similar cohort, distress and perceived impact of the pandemic has worsened. Greater access to cardiac rehabilitation in China could address these issues.
