- Background: The COVID-19 pandemic carries a high burden of morbidity and mortality worldwide. We aimed to identify possible predictors of in-hospital major cardiovascular (CV) events in COVID-19.Methods: We retrospectively included patients hospitalized for COVID-19 from 10 centers. Clinical, biochemical, electrocardiographic, and imaging data at admission and medications were collected. Primary endpoint was a composite of in-hospital CV death, acute heart failure (AHF), acute myocarditis, arrhythmias, acute coronary syndromes (ACS), cardiocirculatory arrest, and pulmonary embolism (PE).Results: Of the 748 patients included, 141(19%) reached the set endpoint: 49 (7%) CV death, 15 (2%) acute myocarditis, 32 (4%) sustained-supraventricular or ventricular arrhythmias, 14 (2%) cardiocirculatory arrest, 8 (1%) ACS, 41 (5%) AHF, and 39 (5%) PE. Patients with CV events had higher age, body temperature, creatinine, high-sensitivity troponin, white blood cells, and platelet counts at admission and were more likely to have systemic hypertension, renal failure (creatinine ≥ 1.25 mg/dL), chronic obstructive pulmonary disease, atrial fibrillation, and cardiomyopathy. On univariate and multivariate analysis, troponin and renal failure were associated with the composite endpoint. Kaplan–Meier analysis showed a clear divergence of in-hospital composite event-free survival stratified according to median troponin value and the presence of renal failure (Log rank p < 0.001).Conclusions: Our findings, derived from a multicenter data collection study, suggest the routine use of biomarkers, such as cardiac troponin and serum creatinine, for in-hospital prediction of CV events in patients with COVID-19.

- Background: Acute heart failure (AHF) is the first cause of hospitalization for over-65 individuals, associated with high mortality and readmission rate. The aim of this study was to assess the prognostic value of a multiparametric score combining clinical, biochemical and echocardiographic indexes in AHF for clinical practice.Methods: 830 patients hospitalized for AHF were enrolled. Exclusion criteria were: active neoplasms; previous heart transplantation or left ventricular assist device implantation. Different variables were analyzed: etiology of AHF, clinical and biochemical data, lung congestion on chest-X ray, echocardiographic parameters and administered therapy. The endpoints were: all-cause mortality at 30 days, 6 months and 5 years and the duration of hospitalization.Results: 771 patients met eligibility criteria. Using the univariate and multivariate analysis the indexes with the best correlation with outcome were discretized and used to create the ACUTE HF score, computed as: 1.4*[serum creatinine>2 mg/dl] + 0.8*[ejection fraction<30] + 0.7*[age > 76] + 0.7*[prior hospitalization for AHF] + 0.9*[prior stroke/transient ischemic attack] + 0.5*[more than moderate mitral regurgitation] + 0.8*[use of non-invasive ventilation] and used to divide patients into 3 groups according to the risk of 6-months mortality. With the receiver operating curves and Kaplan-Meier analysis, this score proved to have a high predictive power for mortality at 30 days, 6 months and 5 years from hospitalization, and for event-free survival rates, providing a risk stratification capability superior to that of single variables.Conclusions: The ACUTE HF score could be a complete and useful tool for assessing prognosis of AHF patients. It could represent a step in the long standardization pathway of prognostic protocols for AHF.

- The aim of the present study was to explore the relation between right ventricular (RV) and left ventricular (LV) echocardiographic parameters with clinical outcome in patients with advanced heart failure referred for cardiac transplantation. Ninety-eight consecutive patients with advanced systolic heart failure, referred for cardiac transplant evaluation, were enrolled. All patients were prospectively followed for the development of new outcome events, which included hospitalization for acute heart failure, cardiovascular death, heart transplantation, intra-aortic balloon pump implantation, and ventricular assist device implantation. Conventional transthoracic echocardiography was performed in all subjects. RV longitudinal strain (RVLS) by speckle-tracking echocardiography was assessed by averaging all segments in apical 4-chamber view (global RVLS) and by averaging RV free-wall segments (free-wall RVLS). LV global longitudinal and global circumferential strains were also calculated. Of the 98 subjects at baseline, 46 had 67 new events during a mean follow-up of 1.5 +/- 0.9 years. Free-wall RVLS, global RVLS, N-terminal fragment of the prohormone brain natriuretic peptide, RV fractional area change, and LV end-diastolic volume were independently predictive of combined outcomes (all p<0.0001). The overall performance for the prediction of cardiovascular events was greatest for free-wall RVLS (area under the curve free-wall RVLS: 0.87; global RVLS: 0.67; RV fractional area change: 0.60; N-terminal fragment of the prohormone brain natriuretic peptide, 0.62; global circumferential strain: 0.55; global longitudinal strain: 0.35; and LV ejection fraction: 0.26). Free-wall RVLS showed the highest adjusted hazards ratio. A graded association between the grade of RV dysfunction and the risk of cardiovascular events was only evident for free-wall RVLS and global RVLS. In conclusion, in patients referred for heart transplantation, RVLS is a stronger predictor of outcome than LV longitudinal strain and other conventional parameters, providing a stronger prognostic stratification.

- Coronavirus disease-2019 (COVID-19) outbreak has become a worldwide healthcare emergency, with continuously growing number of infected subjects. Considering the easy virus spread through respiratory droplets produced with cough, sneezes or spit or through close contact with infected people or surfaces, healthcare workers are further exposed to COVID-19. Particularly, echocardiography remains an essential diagnostic service which, due to the close contact with patients during the exam, provides echocardiographers high-risk of contagion. Therefore, the common modalities of performing echocardiography should be improved in this scenario, avoiding performing unnecessary exams, using the appropriate personal protective equipment depending on patients' status and location, optimizing time-effectiveness of the echocardiographic study and accurately sanitizing the environment and devices after each exam. This paper aims to provide a simple guide for the clinicians to balance between providing the best care to each patient and protecting themselves and other patients from the spread of the virus. It also proposes the use of the mnemonic PREVENT to resume the crucial indications to be followed for the execution of appropriate echocardiographic examination during the COVID-19 pandemic.

- Aims: In patients with heart failure with reduced ejection fraction (HFrEF), an association between left atrial (LA) dilatation and dysfunction is expected, but the degree of coexistence of the two abnormalities and their relative prognostic role is not known.Methods and results: A total of 626 HFrEF patients formed the study population. All of them underwent a comprehensive echocardiographic evaluation. LA maximal volume was indexed to body surface area (LAVi); LA function was assessed using strain analysis during the reservoir phase: peak atrial longitudinal strain (PALS) analysis. Study primary endpoint was overall mortality or hospitalization for worsening heart failure. Four groups of patients were included in this study according to LAVi (≤34 or >34 mL/m2 ) and PALS (≤23% or >23%); 61 (10%) patients had normal LA volume and function (Group 1), 58 (9%) had LA dilatation but normal function (Group 2), 100 (16%) had normal volume but abnormal function (Group 3), and 407 (65%) had enlarged left atrium and abnormal function (Group 4). PALS was associated with primary endpoint in patients with both normal-size [Groups 1 and 3: hazard ratio (HR) 0.92, 95% confidence interval (CI) 0.88-0.96; P = 0.0006] and dilated left atria (Groups 2 and 4: HR 0.93, 95% CI 0.91-0.96; P < 0.0001). In contrast, LAVi was associated with the primary endpoint in patients with abnormal LA function (Groups 3 and 4: HR 1.018, 95% CI 1.011-1.024; P < 0.00001) but not in those with normal PALS (Groups 1 and 2: HR 1.023, 95% CI 0.99-1.057; P = 0.1).Conclusions: Left atrial dilatation and dysfunction frequently but not invariably coexist. PALS emerged as a significant prognostic parameter in HFrEF even in the absence of LA dilation.
