ABSTRACT

Acute viral myocarditis is a serious complication of viral infectious diseases, including coronavirus disease 2019 (COVID-19). To better understand the pathogenesis of acute viral myocarditis, we retrospectively analyzed the incidence and prognostic significance of hypocalcemia among patients with acute myocarditis, most of whom were considered to have acute viral myocarditis. We retrospectively reviewed the demographic and clinical data of patients with clinically confirmed acute myocarditis treated in our hospital over a 13-year period from 2006 to 2019, including laboratory results, cardiac imaging findings, and clinical outcomes. These data were compared between lower, middle, and higher calcium groups depending on the minimum calcium level measured during hospitalization. Among the 288 patients with acute myocarditis included, the hypocalcemia group (lower calcium group) had poorer clinical and laboratory results, received more medications and device support, and experienced poorer outcomes, including heart failure, arrhythmias, and death. Specifically, the left ventricular ejection fraction was significantly lower, and the length of hospital stay was significantly longer in the hypocalcemia group than in the other two groups. Furthermore, the incidence rates of atrioventricular block, ventricular tachycardia/ventricular fibrillation, cardiogenic shock, and mortality were significantly higher in the hypocalcemia group. Multivariate Cox regression analysis identified hypocalcemia as an independent risk factor for 30-day mortality in patients with acute myocarditis. In conclusion, the clinical evidence provided by the present study indicates that hypocalcemia is a risk factor for poorer outcomes in patients with acute myocarditis that should be considered carefully in the diagnosis and treatment of these patients.

ABSTRACT

BACKGROUND: The expense of clinical trials mandates new strategies to efficiently generate evidence and test novel therapies. In this context, we designed a decentralized, patient-centered randomized clinical trial leveraging mobile technologies, rather than in-person site visits, to test the efficacy of 12 weeks of canagliflozin for the treatment of heart failure, regardless of ejection fraction or diabetes status, on the reduction of heart failure symptoms. METHODS: One thousand nine hundred patients will be enrolled with a medical record-confirmed diagnosis of heart failure, stratified by reduced (≤40%) or preserved (>40%) ejection fraction and randomized 1:1 to 100 mg daily of canagliflozin or matching placebo. The primary outcome will be the 12-week change in the total symptom score of the Kansas City Cardiomyopathy Questionnaire. Secondary outcomes will be daily step count and other scales of the Kansas City Cardiomyopathy Questionnaire. RESULTS: The trial is currently enrolling, even in the era of the coronavirus disease 2019 (COVID-19) pandemic. CONCLUSIONS: CHIEF-HF (Canagliflozin: Impact on Health Status, Quality of Life and Functional Status in Heart Failure) is deploying a novel model of conducting a decentralized, patient-centered, randomized clinical trial for a new indication for canagliflozin to improve the symptoms of patients with heart failure. It can model a new method for more cost-effectively testing the efficacy of treatments using mobile technologies with patient-reported outcomes as the primary clinical end point of the trial.

ABSTRACT

INTRODUCCIÓN: La pandemia de enfermedad por coronavirus 2019 (COVID-19) ha incidido de forma negativa en los programas de rehabilitación cardiaca (PRC) españoles. OBJETIVO: Este trabajo tiene como objetivo fundamental el analizar la posibilidad de mantenerlos abiertos y como secundario valorar si se mantienen los beneficios demostrados a nivel físico y psicológico. MÉTODOS: Analizamos los resultados de nuestro PRC en el año 2020 (119 pacientes) y los comparamos con los del año 2019 (121 pacientes), libre de COVID-19. Se comparan distintas variables generales, y los resultados obtenidos en capacidad física, a nivel psicológico, así como las complicaciones y abandonos. RESULTADOS: No existen diferencias significativas entre ambos grupos en la edad (61.6 vs. 61.5), sexo (mujeres: 12.6 vs. 14.8%), diagnóstico de cardiopatía isquémica (106 vs. 99) y fracción de eyección de ventrículo izquierdo (55.9 vs. 55.8%). La ansiedad media-alta fue superior al inicio (p = 0.02) y final (p = 0.002) del programa en el año 2019, así como las puntuaciones del patrón de conducta tipo A (p = 0.041 vs. 0.034). El porcentaje de depresión fue similar. Más del 95% de los pacientes del año 2020 referían miedo al contagio. La capacidad funcional aumentó, pero menos en el año 2020 (p = 0.001). La duración del programa fue superior en el año 2020 (p = 0.001). Los abandonos (15 vs. 11 pacientes) no mostraron diferencias significativas. CONCLUSIONES: Los PRC en época COVID-19 son posibles y siguen mostrando beneficios. La duración del programa fue mayor por periodos de falta de asistencia. La menor capacidad física puede estar relacionada con el uso de la mascarilla. INTRODUCTION: COVID-19 pandemic has had a negative impact on Spanish Cardiac Rehabilitation Programmes (CRP). OBJECTIVES: The main objective of this study is to analyze the possibility of keeping these units open and, secondly, to assess whether demonstrated physical and psychological benefits are preserved. METHODS: We analyzed results of our CRP in 2020 (119 patients) and compared them with those of 2019 (121 patients), year free of Covid. We compare different general variables, and results obtained in physical capacity, psychological level, as well as complications and dropouts. RESULTS: There were no significant differences between two groups in age (61.6 vs. 61.5), sex (women: 12.6% vs. 14.8%), diagnosis of ischemic heart disease (106 vs. 99) and left ventricular ejection fraction (55.9% vs. 55.8%). Mean-high anxiety was higher at baseline (p = 0.02) and endline (p = 0.002) of program in 2019, as well as type A behavior pattern scores (p=0.041 and 0.034). Percentage of depression was similar. More than 95% of patients in 2020 reported fear of infection. Functional capacity increased, but less in 2020 (p = 0.001). Programme duration was longer in 2020 (p=0.001). Dropouts (15 vs. 11 patients) showed no significant differences. CONCLUSIONS: CR programmes in COVID-19 era are possible and continue to show benefits. The duration of programme was longer due to periods of non-attendance. Lower physical capacity may be related to mask use.

ABSTRACT

OBJECTIVE: To study the cardiac outcomes of patients with multisystem inflammatory syndrome in children (MIS-C) after 6-month of diagnosis. METHODS: This review of hospital records was conducted on MIS-C patients (aged <21 year) who completed a six-month follow up. The baseline demographic, clinical, laboratory, and treatment characteristics during the acute phase, and echocardiographic findings during follow-up were collected. RESULTS: 116 patients (61.2% male, median age 7 years) with MIS-C were included in the study. At the time of admission, cardiac abnormalities were present in 70.7% of MIS-C patients, and the most common cardiac abnormalities were valve failure (50.9%), followed by ventricular dysfunction (39.7%), and pericardial effusion (23.3%). Six month after diagnosis, cardiac abnormalities were found in 10.3% of patients, and patients had lower rates of ventricular dysfunction (P<0.001), valve failure (P<0.001), pericardial effusion (P<0.001), and coronary involvement (P<0.001) as composed to the baseline. Intravenous immunoglobulin (IVIG) and steroid treatment significantly reduced the odds of occurrence of ventricular dysfunction (P=0.002), valve failure (P=0.004), and low ejection fraction (P=0.002) in comparison to IVIG treatment. CONCLUSION: While most MIS-C patients had abnormal echocardiographic findings at admission, only 10.3% of patients had cardiac abnormalities during follow up.

ABSTRACT

AIMS: We conducted a meta-analysis of randomised controlled trials (RCTs) of implantable haemodynamic monitoring (IHM)-guided care. METHODS: PubMed and Ovid MEDLINE were searched for RCTs of IHM in patients with heart failure (HF). Outcomes were examined in total (first and recurrent) event analyses. RESULTS: Five trials comparing IHM-guided care with standard care alone were identified and included 2710 patients across ejection fraction (EF) ranges. Data were available for 628 patients (23.2%) with heart failure with preserved ejection fraction (HFpEF) (EF ≥50%) and 2023 patients (74.6%) with heart failure with a reduced ejection fraction (HFrEF) (EF <50%). Chronicle, CardioMEMS and HeartPOD IHMs were used. In all patients, regardless of EF, IHM-guided care reduced total HF hospitalisations (HR 0.74, 95% CI 0.66 to 0.82) and total worsening HF events (HR 0.74, 95% CI 0.66 to 0.84). In patients with HFrEF, IHM-guided care reduced total worsening HF events (HR 0.75, 95% CI 0.66 to 0.86). The effect of IHM-guided care on total worsening HF events in patients with HFpEF was uncertain (fixed-effect model: HR 0.72, 95% CI 0.59 to 0.88; random-effects model: HR 0.60, 95% CI 0.32 to 1.14). IHM-guided care did not reduce mortality (HR 0.92, 95% CI 0.71 to 1.20). IHM-guided care reduced all-cause mortality and total worsening HF events (HR 0.80, 95% CI 0.72 to 0.88). CONCLUSIONS: In patients with HF across all EFs, IHM-guided care reduced total HF hospitalisations and worsening HF events. This benefit was consistent in patients with HFrEF but not consistent in HFpEF. Further trials with pre-specified analyses of patients with an EF of ≥50% are required.

ABSTRACT

PURPOSE: We aimed to better understand the pathophysiology of SARS-CoV-2 pneumonia in non-critically ill hospitalized patients secondarily presenting with clinical deterioration and increase in oxygen requirement without any identified worsening factors. METHODS: We consecutively enrolled patients without clinical or biological evidence for superinfection, without left ventricular dysfunction and for whom a pulmonary embolism was discarded by computed tomography (CT) pulmonary angiography. We investigated lung ventilation and perfusion (LVP) by LVP scintigraphy, and, 24 h later, left and right ventricular function by Tc-99m-labeled albumin-gated blood-pool scintigraphy with late (60 mn) tomographic albumin images on the lungs to evaluate lung albumin retention that could indicate microvascular injuries with secondary edema. RESULTS: We included 20 patients with confirmed SARS-CoV-2 pneumonia. All had CT evidence of organizing pneumonia and normal left ventricular ejection fraction. No patient demonstrated preserved ventilation with perfusion defect (mismatch), which may discard a distal lung thrombosis. Patterns of ventilation and perfusion were heterogeneous in seven patients (35%) with healthy lung segments presenting a relative paradoxical hypoperfusion and hypoventilation compared with segments with organizing pneumonia presenting a relative enhancement in perfusion and preserved ventilation. Lung albumin retention in area of organizing pneumonia was observed in 12 patients (60%), indicating microvascular injuries, increase in vessel permeability, and secondary edema. CONCLUSION: In hospitalized non-critically ill patients without evidence of superinfection, pulmonary embolism, or cardiac dysfunction, various types of damage may contribute to clinical deterioration including microvascular injuries and secondary edema, inconsistencies in lung segments vascularization suggesting a dysregulation of the balance in perfusion between segments affected by COVID-19 and others. SUMMARY STATEMENT: Microvascular injuries and dysregulation of the balance in perfusion between segments affected by COVID-19 and others are present in non-critically ill patients without other known aggravating factors. KEY RESULTS: In non-critically ill patients without evidence of superinfection, pulmonary embolism, macroscopic distal thrombosis or cardiac dysfunction, various types of damage may contribute to clinical deterioration including 1/ microvascular injuries and secondary edema, 2/ inconsistencies in lung segments vascularization with hypervascularization of consolidated segments contrasting with hypoperfusion of not affected segments, suggesting a dysregulation of the balance in perfusion between segments affected by COVID-19 and others.

ABSTRACT

The Coronavirus Disease 2019 (COVID-19) pandemic has transformed health systems worldwide. There is conflicting data regarding the degree of cardiovascular involvement following infection. A registry was designed to evaluate the prevalence of echocardiographic abnormalities in adults recovered from COVID-19. We prospectively evaluated 595 participants (mean age 45.5 ± 14.9 years; 50.8% female) from 10 institutions in Argentina and Brazil. Median time between infection and evaluation was two months, and 82.5% of participants were not hospitalized for their infection. Echocardiographic studies were conducted with General Electric equipment; 2DE imaging and global longitudinal strain (GLS) of both ventricles were performed. A total of 61.7% of the participants denied relevant cardiovascular history and 41.8% had prolonged symptoms after resolution of COVID-19 infection. Mean left ventricular ejection fraction (LVEF) was 61.0 ± 5.5% overall. In patients without prior comorbidities, 8.2% had some echocardiographic abnormality: 5.7% had reduced GLS, 3.0% had a LVEF below normal range, and 1.1% had wall motion abnormalities. The right ventricle (RV) was dilated in 1.6% of participants, 3.1% had a reduced GLS, and 0.27% had reduced RV function. Mild pericardial effusion was observed in 0.82% of participants. Male patients were more likely to have new echocardiographic abnormalities (OR 2.82, p = 0.002). Time elapsed since infection resolution (p = 0.245), presence of symptoms (p = 0.927), or history of hospitalization during infection (p = 0.671) did not have any correlation with echocardiographic abnormalities. Cardiovascular abnormalities after COVID-19 infection are rare and usually mild, especially following mild infection, being a low GLS of left and right ventricle, the most common ones in our registry. Post COVID cardiac abnormalities may be more frequent among males.

ABSTRACT

STUDY OBJECTIVE: Dynamic arterial elastance (Eadyn) has been suggested as a functional measure of arterial load. We aimed to evaluate whether pre-induction Eadyn can predict post-induction hypotension. DESIGN: Prospective observational study. PATIENTS: Adult patients undergoing general anesthesia with invasive and non-invasive arterial pressure monitoring systems. MEASUREMENTS: We collected invasive and non-invasive Eadyns (n = 38 in each), respectively. In both invasive and non-invasive Eadyns, pre-induction Eadyns were obtained during one-minute tidal and deep breathing in each patient before anesthetic induction. Post-induction hypotension was defined as a decrease of >30% in mean blood pressure from the baseline value or any absolute mean blood pressure value of <65 mmHg for 10 min after anesthetic induction. The predictabilities of Eadyns for the development of post-induction hypotension were tested using receiver-operating characteristic curve analysis. MAIN RESULTS: Invasive Eadyn during deep breathing showed significant predictability with an area under the curve (AUC) of 0.78 (95% Confidence interval [CI], 0.61-0.90, P = 0.001). But non-invasive Eadyn during tidal breathing (AUC = 0.66, 95% CI, 0.49-0.81, P = 0.096) and deep breathing (AUC = 0.53, 95% CI, 0.36-0.70, P = 0.75), and invasive Eadyn during tidal breathing (AUC = 0.66, 95% CI, 0.41-0.74, P = 0.095) failed to predict post-induction hypotension. CONCLUSION: In our study, invasive pre-induction Eadyn during deep breathing -could predict post-induction hypotension. Despite its invasiveness, future studies will be needed to evaluate the usefulness of Eadyn as a predictor of post-induction hypotension because it is an adjustable parameter.

ABSTRACT

INTRODUCTION: The sequelae of COVID-19 have been described as a multisystemic condition, with a great impact on the cardiovascular and pulmonary systems with abnormalities in pulmonary function tests, such as lower diffusing capacity of the lung for carbon monoxide (DLco) levels and pathological patterns in spirometry; persistence of radiological lesions; cardiac involvement such as myocarditis and pericarditis; and an increase in mental disorders such as anxiety and depression. Several factors, such as infection severity during the acute phase as well as vaccination status, have shown some variable effects on these post-COVID-19 conditions, mainly at a clinical level such as symptoms persistence. Longitudinal assessments and reversibility of changes across the spectrum of disease severity are required to understand the long-term impact of COVID-19. METHODS AND ANALYSIS: A prospective cohort study aims to assess the impact of SARS-CoV-2 infection on cardiopulmonary function and quality of life after the acute phase of the disease over a 6-month follow-up period. Sample size was calculated to recruit 200 participants with confirmatory COVID-19 tests who will be subsequently classified according to infection severity. Four follow-up visits at baseline, month 1, month 3 and month 6 after discharge from the acute phase of the infection will be scheduled as well as procedures such as spirometry, DLco test, 6-minute walk test, chest CT scan, echocardiogram, ECG, N-terminal pro-B-type natriuretic peptide measurement and RAND-36 scale. Primary outcomes are defined as abnormal pulmonary function test considered as DLco <80%, abnormal cardiovascular function considered as left ventricular ejection fraction <50% and abnormal quality of life considered as a <40 score for each sphere in the RAND-36-Item Short Form Health Survey. ETHICS AND DISSEMINATION: The study protocol was approved by the Institutional Ethics Committee of the Universidad Peruana Cayetano Heredia (SIDISI 203725) and the Ethics Committee of the Hospital Cayetano Heredia (042-2021). Protocol details were uploaded in ClinicalTrials.gov. Findings will be disseminated through peer-reviewed journals, scientific conferences and open-access social media platforms. TRIAL REGISTRATION NUMBER: NCT05386485.

ABSTRACT

BACKGROUND: Cardiovascular manifestations in patients with COVID-19 are associated with dire outcomes. Long COVID syndrome is the persistence of symptoms after acute disease and is found in up to 40% of subjects. There is little information regarding subacute echocardiographic manifestations after COVID-19, and no study has included a Mexican mestizo population. METHODS: This cross-sectional study included subjects older than 18 with an episode of COVID-19 in the last 3 months. Those with previously known cardiovascular disease were excluded. The patient´s medical history and COVID-19 information were obtained from clinical charts. We performed a transthoracic echocardiogram in every subject and determined left ventricular (LV) index mass, LV ejection fraction (LVEF), left ventricular global longitudinal strain (LV GLS), right ventricular (RV) GLS, and tricuspid annular plane systolic excursion (TAPSE). A descriptive and comparative analysis was performed based on symptom severity and persistence. RESULTS: One hundred subjects were included; 63% were classified with mild and 37% with moderate to severe COVID-19. The median of LVEF was 60% (55-60), LV GLS and RV GLS was impaired in 34% and 74% of patients, respectively. Patients with moderate to severe disease had significantly lower LVEF (Mean Difference: -3.3), TAPSE (mean difference: -1.8), and higher (worse) LV GLS (Mean Difference: 2.5) and RV GLS (mean difference: 2.9). Persistent symptoms were associated with lower TAPSE and higher RVGLS. CONCLUSIONS: Patients who recover from COVID-19 have a high prevalence of subtle RV and LV dysfunction using GLS analysis. A moderate to severe episode was associated with worse RV and LV function measured by RV GLS, TAPSE, and LV GLS. Subjects with persistent symptoms had worse RVGLS and TAPSE.

ABSTRACT

Heart failure exacerbations impart significant morbidity and mortality, however, large- scale studies assessing outcomes in the setting of concurrent coronavirus disease-19 (COVID-19) are limited. We utilized National Inpatient Sample (NIS) database to compare clinical outcomes in patients admitted with acute congestive heart failure exacerbation (CHF) with and without COVID-19 infection. A total of 2,101,980 patients (Acute CHF without COVID-19 (n = 2,026,765 (96.4%) and acute CHF with COVID-19 (n = 75,215, 3.6%)) were identified. Multivariate logistic regression analysis was utilized to compared outcomes and were adjusted for age, sex, race, income level, insurance status, discharge quarter, Elixhauser co-morbidities, hospital location, teaching status and bed size. Patients with acute CHF and COVID-19 had higher in-hospital mortality compared to patients with acute CHF alone (25.78% vs. 5.47%, adjust OR (aOR) 6.3 (95% CI 6.05-6.62, p < 0.001)) and higher rates of vasopressor use (4.87% vs. 2.54%, aOR 2.06 (95% CI 1.86-2.27, p < 0.001), mechanical ventilation (31.26% vs. 17.14%, aOR 2.3 (95% CI 2.25-2.44, p < 0.001)), sudden cardiac arrest (5.73% vs. 2.88%, aOR 1.95 (95% CI 1.79-2.12, p < 0.001)), and acute kidney injury requiring hemodialysis (5.56% vs. 2.94%, aOR 1.92 (95% CI 1.77-2.09, p < 0.001)). Moreover, patients with heart failure with reduced ejection fraction had higher rates of in-hospital mortality (26.87% vs. 24.5%, adjusted OR 1.26 (95% CI 1.16-1.36, p < 0.001)) with increased incidence of vasopressor use, sudden cardiac arrest, and cardiogenic shock as compared to patients with heart failure with preserved ejection fraction. Furthermore, elderly patients and patients with African-American and Hispanic descents had higher in-hospital mortality. Acute CHF with COVID-19 is associated with higher in-hospital mortality, vasopressor use, mechanical ventilation, and end organ dysfunction such as kidney failure and cardiac arrest.

ABSTRACT

BACKGROUND: Long COVID is associated with multiple symptoms and impairment in multiple organs. Cross-sectional studies have reported cardiac impairment to varying degrees by varying methodologies. Using cardiac MR (CMR), we investigated a 12-month trajectory of abnormalities in Long COVID. OBJECTIVES: To investigate cardiac abnormalities 1-year post-SARS-CoV-2 infection. METHODS: 534 individuals with Long COVID underwent CMR (T1/T2 mapping, cardiac mass, volumes, function and strain) and multiorgan MRI at 6 months (IQR 4.3-7.3) since first post-COVID-19 symptoms. 330 were rescanned at 12.6 (IQR 11.4-14.2) months if abnormal baseline findings were reported. Symptoms, questionnaires and blood samples were collected at both time points. CMR abnormalities were defined as ≥1 of low left or right ventricular ejection fraction (LVEF), high left or right ventricular end diastolic volume, low 3D left ventricular global longitudinal strain (GLS), or elevated native T1 in ≥3 cardiac segments. Significant change over time was reported by comparison with 92 healthy controls. RESULTS: Technical success of multiorgan and CMR assessment in non-acute settings was 99.1% and 99.6% at baseline, and 98.3% and 98.8% at follow-up. Of individuals with Long COVID, 102/534 (19%) had CMR abnormalities at baseline; 71/102 had complete paired data at 12 months. Of those, 58% presented with ongoing CMR abnormalities at 12 months. High sensitivity cardiac troponin I and B-type natriuretic peptide were not predictive of CMR findings, symptoms or clinical outcomes. At baseline, low LVEF was associated with persistent CMR abnormality, abnormal GLS associated with low quality of life and abnormal T1 in at least three segments was associated with better clinical outcomes at 12 months. CONCLUSION: CMR abnormalities (left entricular or right ventricular dysfunction/dilatation and/or abnormal T1mapping), occurred in one in five individuals with Long COVID at 6 months, persisting in over half of those at 12 months. Cardiac-related blood biomarkers could not identify CMR abnormalities in Long COVID. TRIAL REGISTRATION NUMBER: NCT04369807.

ABSTRACT

In the last years, major progress occurred in heart failure (HF) management. Quadruple therapy is now mandatory for all the patients with HF with reduced ejection fraction. Whilst verciguat is becoming available across several countries, omecamtiv mecarbil is waiting to be released for clinical use. Concurrent use of potassium-lowering agents may counteract hyperkalaemia and facilitate renin-angiotensin-aldosterone system inhibitor implementations. The results of the EMPagliflozin outcomE tRial in Patients With chrOnic heaRt Failure With Preserved Ejection Fraction (EMPEROR-Preserved) trial were confirmed by the Dapagliflozin in Heart Failure with Mildly Reduced or Preserved Ejection Fraction (DELIVER) trial, and we now have, for the first time, evidence for treatment of also patients with HF with preserved ejection fraction. In a pre-specified meta-analysis of major randomized controlled trials, sodium-glucose co-transporter-2 inhibitors reduced all-cause mortality, cardiovascular (CV) mortality, and HF hospitalization in the patients with HF regardless of left ventricular ejection fraction. Other steps forward have occurred in the treatment of decompensated HF. Acetazolamide in Acute Decompensated Heart Failure with Volume Overload (ADVOR) trial showed that the addition of intravenous acetazolamide to loop diuretics leads to greater decongestion vs. placebo. The addition of hydrochlorothiazide to loop diuretics was evaluated in the CLOROTIC trial. Torasemide did not change outcomes, compared with furosemide, in TRANSFORM-HF. Ferric derisomaltose had an effect on the primary outcome of CV mortality or HF rehospitalizations in IRONMAN (rate ratio 0.82; 95% confidence interval 0.66-1.02; P = 0.070). Further options for the treatment of HF, including device therapies, cardiac contractility modulation, and percutaneous treatment of valvulopathies, are summarized in this article.

ABSTRACT

AIMS: Several patients with heart failure and reduced ejection fraction (HFrEF) do not receive renin-angiotensin-aldosterone system (RAAS) inhibitors at the recommended dose or at all, frequently due to actual or feared hyperkalaemia. Sodium zirconium cyclosilicate (SZC) is an orally administered non-absorbed intestinal potassium binder proven to lower serum potassium concentrations. METHODS AND RESULTS: PRIORITIZE-HF was an international, multicentre, parallel-group, randomized, double-blind, placebo-controlled study to evaluate the benefits and risks of using SZC to intensify RAAS inhibitor therapy. Patients with symptomatic HFrEF were eligible and randomly assigned to receive SZC 5 g or placebo once daily for 12 weeks. Doses of study medication and RAAS inhibitors were titrated during the treatment period. The primary endpoint was the proportion of patients at 12 weeks in the following categories: (i) any RAAS inhibitor at less than target dose, and no MRA; (ii) any RAAS inhibitor at target dose and no MRA; (ii) MRA at less than target dose; and (iv) MRA at target dose. Due to challenges in participant management related to the COVID-19 pandemic, the study was prematurely terminated with 182 randomized patients. There was no statistically significant difference in the distribution of patients by RAAS inhibitor treatment categories at 3 months (P = 0.43). The proportion of patients at target MRA dose was numerically higher in the SZC group (56.4%) compared with the placebo group (47.0%). Overall, SZC was well tolerated. CONCLUSIONS: PRIORITIZE-HF was terminated prematurely due to COVID-19 and did not demonstrate a statistically significant increase in the intensity of RAAS inhibitor therapies with the potassium-reducing agent SZC compared with placebo.

ABSTRACT

BACKGROUND: With the rapid rollout of COVID-19 vaccinations, numerous associated and suspected adverse events have been reported nationally and worldwide. Literature reporting confirmed cases of pericarditis and myocarditis following SARS-CoV-2 mRNA vaccinations has evolved, with a predominance in adolescent males following the second dose. METHODS: This was a retrospective analysis of all patients presenting to St Vincent's Hospital, Sydney, Australia with suspected COVID-19 vaccine-related myocarditis and pericarditis. The Brighton Collaboration Case Definitions of Myocarditis and Pericarditis were used to categorise patients into groups based on diagnostic certainty. Cardiac magnetic resonance imaging findings were reviewed against updated Lake Louise Criteria for diagnosing patients with suspected myocarditis. RESULTS: We report 10 cases of confirmed, possible or probable myocarditis and pericarditis. The mean age of presentation in the vaccine group was 33±9.0 years. The most common presenting symptom was pleuritic chest pain (n=8, 80%). Eight patients (80%) had electrocardiogram (ECG) abnormalities (n=6 pericarditis, n=2 myocarditis). Five patients (50%) had a minimum 24 hours of cardiac monitoring. One patient had multisystem inflammatory syndrome following vaccination (MIS-V) with severely impaired left ventricular ejection fraction and required admission to the intensive care unit. DISCUSSION AND CONCLUSION: Cardiac complications post mRNA vaccines are rare. Our case series reflects the worldwide data that vaccine-related myocarditis and pericarditis most frequently occur in young males, following the second dose of the vaccine. These cardiac side effects are mild and self-limiting, with adequate responses to oral anti-inflammatories. One patient developed a severe reaction, with no fatal cases.

ABSTRACT

Aim      To determine the effect of major electrocardiographic (ECG) parameters on the prognosis of patients with COVID-19.Material and methods  One of systemic manifestations of COVID-19 is heart injury. ECG is the most simple and available method for diagnosing the heart injury, which influences the therapeutic approach. This study included 174 hospitalized patients with COVID-19. Major ECG parameters recorded on admission and their changes before the discharge from the hospital or death of the patient, were analyzed, and the effect of each parameter on the in-hospital prognosis was determined. Results were compared with the left ventricular ejection fraction (LV EF), laboratory data, and results of multispiral computed tomography (MSCT) of the lungs.Results ECG data differed on admission and their changes differed for deceased and discharged patients. Of special interest was the effect of the QRS complex duration at baseline and at the end of treatment on the in-hospital survival and mortality rate. The Cox regression analysis showed that the QRS complex duration (relative risk (RR) 2.07, 95% confidence interval (CI): 1.17-3.66; р=0.01), MSCT data (RR, 1.54; 95 % CI: 1.14-2.092; р=0.005), and glomerular filtration rate (GFR) (RR, 0.98; 95 % CI: 0.96-0.99; р=0.001) had the highest predictive significance. In further comparison of these three indexes, the QRS duration and GFR retained their predictive significance, and a ROC analysis showed that the cut-off QRS complex duration was 125 ms (р=0.001). Patients who developed left bundle branch block (LBBB) in the course of disease also had an unfavorable prognosis compared to other intraventricular conduction disorders (р=0.038). The presence of LBBB was associated with reduced LV EF (р=0.0078). The presence of atrial fibrillation (AF) significantly predetermines a worse outcome both at the start (р=0.011) and at the end of observation (р=0.034). A higher mortality was observed for the group of deceased patients with ST segment deviations, ST elevation (р=0.0059) and ST depression (р=0.028).Conclusion      Thus, the QTc interval elongation, LBBB that developed during the treatment, AF, and increased QRS complex duration are the indicators that determine the in-hospital prognosis of patients with COVID-19. The strongest electrocardiographic predictor for an unfavorable prognosis was the QRS complex duration that allowed stratification of patients to groups of risk.

ABSTRACT

BACKGROUND: COVID-19 is a great medical challenge as it provokes acute respiratory distress and has pulmonary manifestations and cardiovascular (CV) consequences. AIMS: This study compared cardiac injury in COVID-19 myocarditis patients with non-COVID-19 myocarditis patients. METHODS: Patients who recovered from COVID-19 were scheduled for cardiovascular magnetic resonance (CMR) owing to clinical myocarditis suspicion. The retrospective non-COVID-19 myocarditis (2018-2019) group was enrolled (n = 221 patients). All patients underwent contrast-enhanced CMR, the conventional myocarditis protocol, and late gadolinium enhancement (LGE). The COVID study group included 552 patients at a mean (standard deviation [SD]) age of 45.9 (12.6) years. RESULTS: CMR assessment confirmed myocarditis-like LGE in 46% of the cases (68.5% of the segments with LGE <25% transmural extent), left ventricular (LV) dilatation in 10%, and systolic dysfunction in 16% of cases. The COVID-19 myocarditis group showed a smaller median (interquartile range [IQR]) LV LGE (4.4% [2.9%-8.1%] vs. 5.9% [4.4%-11.8%]; P <0.001), lower LV end-diastolic volume (144.6 [125.5-178] ml vs. 162.8 [136.6-194] ml; P <0.001), limited functional consequence (left ventricular ejection fraction, 59% [54.1%-65%] vs. 58% [52%-63%]; P = 0.01), and a higher rate of pericarditis (13.6% vs. 6%; P = 0.03) compared to non-COVID-19 myocarditis. The COVID-19-induced injury was more frequent in septal segments (2, 3, 14), and non-COVID-19 myocarditis showed higher affinity to lateral wall segments (P <0.01). Neither obesity nor age was associated with LV injury or remodeling in subjects with COVID-19 myocarditis. CONCLUSIONS: COVID-19-induced myocarditis is associated with minor LV injury with a significantly more frequent septal pattern and a higher pericarditis rate than non-COVID-19 myocarditis.

ABSTRACT

A 37-year-old female patient was admitted 16 days after delivery in a hospital for infectious diseases with cough, shortness of breath, and infiltrative changes in the lungs that were interpreted as viral pneumonia. Considering the failure of therapy and the history, peripartum cardiomyopathy was suspected. Examination revealed a decrease in left ventricular ejection fraction to 30 %, ultrasonic signs of lung congestion and bilateral hydrothorax. The patient was diagnosed with peripartum cardiomyopathy accompanied by functional class 4 heart failure. A specific feature of this case was fast positive dynamics with complete regression of the clinical picture of congestion and improvement of the left ventricular myocardial function associated with the treatment.

ABSTRACT

In order to explore the proteomic signatures of epicardial adipose tissue (EAT) related to the mechanism of heart failure with reduced and mildly reduced ejection fraction (HFrEF/HFmrEF) and heart failure (HF) with preserved ejection fraction (HFpEF), a comprehensive proteomic analysis of EAT was made in HFrEF/HFmrEF (n = 5) and HFpEF (n = 5) patients with liquid chromatography-tandem mass spectrometry experiments. The selected differential proteins were verified between HFrEF/HFmrEF (n = 20) and HFpEF (n = 40) by ELISA (enzyme-linked immunosorbent assay). A total of 599 EAT proteins were significantly different in expression between HFrEF/HFmrEF and HFpEF. Among the 599 proteins, 58 proteins increased in HFrEF/HFmrEF compared to HFpEF, whereas 541 proteins decreased in HFrEF/HFmrEF. Of these proteins, TGM2 in EAT was down-regulated in HFrEF/HFmrEF patients and was confirmed to decrease in circulating plasma of the HFrEF/HFmrEF group (p = 0.019). Multivariate logistic regression analysis confirmed plasma TGM2 could be an independent predictor of HFrEF/HFmrEF (p = 0.033). Receiver operating curve analysis indicated that the combination of TGM2 and Gensini score improved the diagnostic value of HFrEF/HFmrEF (p = 0.002). In summary, for the first time, we described the proteome in EAT in both HFpEF and HFrEF/HFmrEF and identified a comprehensive dimension of potential targets for the mechanism behind the EF spectrum. Exploring the role of EAT may offer potential targets for preventive intervention of HF.
