AimsThe purpose of this study was to evaluate the additional prognostic value of echocardiography in acute decompensation of advanced chronic heart failure (CHF), focusing on right ventricular (RV) dysfunction and its interaction with loading conditions. Few data are available on the prognostic role of echocardiography in acute HF and on the significance of pulmonary hypertension in patients with severe RV failure. Methods and resultsA total of 265 NYHA IV patients admitted for acute decompensation of advanced CHF (EF 22 ± 7%, systolic blood pressure 107 ± 20 mmHg) were prospectively enrolled. Fifty-nine patients met the primary composite endpoint of cardiac death, urgent heart transplantation, and urgent mechanical circulatory support implantation at 90 days. Pulmonary hypertension failed to predict events, while patients with a low transtricuspid systolic gradient (TR gradient <20 mmHg) showed a worse outcome [hazard ratio (HR) 2.37, 95% confidence interval (CI) 1.12-5.00, P = 0.02]. RV dysfunction [tricuspid annular plane systolic excursion (TAPSE) ≤14 mm] in the presence of a low TR gradient identified patients at higher risk of events (HR 2.97, 95% CI 1.19-7.41, P = 0.02). Multivariate analysis showed as best predictors of outcome low RV contraction pressure index (RVCPI), defined as TAPSE × TR gradient, and high estimated right atrial pressure (eRAP). Adding RVCPI (<400 mm*mmHg) and eRAP (≥20 mmHg) to conventional clinical (ADHERE risk tree and NT-proBNP) and echocardiographic risk evaluation resulted in an increase in net reclassification improvement of +19.1% and +20.1%, respectively (P = 0.01) and in c-statistic from 0.59 to 0.73 (P < 0.01).
BACKGROUND: Little is known about the coronavirus SARS-CoV-2 disease (COVID-19) in solid organ transplanted patients. We here report a series of heart transplanted patients with COVID-19 from two centers of Italy. METHODS: All heart transplanted patients of Transplant Centers of Bergamo and Torino with a microbiologically confirmed SARS-CoV-2 infection were enrolled. Data collection included clinical presentation, laboratory and radiological findings, treatment and outcome. Follow-up was performed by visit or phone. RESULTS: From February to March 2020 twenty-six heart transplanted patients (age 62 §12 years; 77% males; time from transplant 10 §10 years; 69% with comorbidities) had a microbiologically confirmed COVID-19. The most frequent symptom was fever, followed by cough. Seventeen patients had a pneumonia, 8 of them severe pneumonia. Seven patients died (27%) and 17 (65%) were hospitalized. Discontinuation of immunosuppression was associated with death (71 vs 21%, p=0.02). Conversely, all patients receiving steroids survived (p<0.001). Patients who received heart transplantation during COVID-19 outbreak survived and no acute graft rejection occurred. Patients who died were older than survivors, had a longer time from transplant and a worse clinical presentation at diagnosis. The current regimen enabled the prolonged survival and function of orthotopic cardiac xenografts in altogether 6 of 8 baboons, of which 4 were now added. These results exceed the threshold set by the Advisory Board of the International Society for Heart and Lung Transplantation. CONCLUSIONS: COVID-19 has a significant impact on long term heart transplanted patients. Conversely, SARS-CoV-2 infection seems to have a limited influence on more recent transplants. Our
Aims To assess the proportion of patients with heart failure and reduced ejection fraction (HFrEF) who are eligible for sacubitril/valsartan (LCZ696) based on the European Medicines Agency/Food and Drug Administration (EMA/FDA) label, the PARADIGM‐HF trial and the 2016 ESC guidelines, and the association between eligibility and outcomes. Methods and results Outpatients with HFrEF in the ESC‐EORP‐HFA Long‐Term Heart Failure (HF‐LT) Registry between March 2011 and November 2013 were considered. Criteria for LCZ696 based on EMA/FDA label, PARADIGM‐HF and ESC guidelines were applied. Of 5443 patients, 2197 and 2373 had complete information for trial and guideline eligibility assessment, and 84%, 12% and 12% met EMA/FDA label, PARADIGM‐HF and guideline criteria, respectively. Absent PARADIGM‐HF criteria were low natriuretic peptides (21%), hyperkalemia (4%), hypotension (7%) and sub‐optimal pharmacotherapy (74%); absent Guidelines criteria were LVEF>35% (23%), insufficient NP levels (30%) and sub‐optimal pharmacotherapy (82%); absent label criteria were absence of symptoms (New York Heart Association class I). When a daily requirement of ACEi/ARB ≥ 10 mg enalapril (instead of ≥ 20 mg) was used, eligibility rose from 12% to 28% based on both PARADIGM‐HF and guidelines. One‐year heart failure hospitalization was higher (12% and 17% vs. 12%) and all‐cause mortality lower (5.3% and 6.5% vs. 7.7%) in registry eligible patients compared to the enalapril arm of PARADIGM‐HF. Conclusions Among outpatients with HFrEF in the ESC‐EORP‐HFA HF‐LT Registry, 84% met label criteria, while only 12% and 28% met PARADIGM‐HF and guideline criteria for LCZ696 if requiring ≥ 20 mg and ≥ 10 mg enalapril, respectively. Registry patients eligible for LCZ696 had greater heart failure hospitalization but lower mortality rates than the PARADIGM‐HF enalapril group.
BACKGROUND Short QT syndrome (SQTS) is a congenital ion channel disease characterized by an increased risk of sudden cardiac death. Little is known about the possibility that accelerated repolarization alters mechanical function in SQTS.OBJECTIVES The study investigated the presence of left ventricular dysfunction and mechanical dispersion, assessed by tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE), and their correlation with QT interval duration and genetics.METHODS Fifteen SQTS patients (7 with HERG and 3 with KCNQ1 mutation) were studied. Electrocardiographic and echocardiographic parameters were compared with age-and sex-matched healthy controls.RESULTS When compared to the control group, SQTS patients showed reduced left ventricular contraction (global longitudinal strain: À16.0% Ϯ 3.4% vs À22.6% Ϯ 1.7%, P o .001; myocardial performance index 0.59 Ϯ 0.17 vs 0.34 Ϯ 0.08, P o .001) and a higher incidence of ejection fraction o55% (odds ratio 11, 95% confidence interval 1.045-374, P ¼ .04). Mechanical dispersion assessed by TDI (P o .01) and STE (P o .001) was higher in the SQTS group than in controls; each parameter showed a significant inverse correlation with QT interval but not with QT dispersion.CONCLUSION This study showed that in SQTS systolic function may also be affected. SQTS patients presented a significant dispersion of myocardial contraction. TDI and STE could become part of the evaluation of this rare disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
