Introduction The incidence, characteristics, and prognosis of pulmonary embolism (PE) in Coronavirus disease 2019 (COVID-19) have been poorly investigated. We aimed to investigate the prevalence and the correlates with the occurrence of PE as well as the association between PE and the risk of mortality in COVID-19. Methods Retrospective multicenter study on consecutive COVID-19 patients hospitalized at 7 Italian Hospitals. At admission, all patients underwent medical history, laboratory and echocardiographic evaluation. Results The study population consisted of 224 patients (mean age 69 ± 14, male sex 62%); PE was diagnosed in 32 cases (14%). Patients with PE were hospitalized after a longer time since symptoms onset (7 IQR 3–11 days, 3 IQR 1–6 days; p = 0.001) and showed higher D-dimers level (1819 IQR 568–5017 ng/ml vs 555 IQR 13–1530 ng/ml; p < 0.001) and higher prevalence of myocardial injury(47% vs 28%, p = 0.033). At multivariable analysis, tricuspid annular plane systolic excursion (TAPSE; HR = 0.84; 95% CI 0.66–0.98; p = 0.046) and systolic pulmonary arterial pressure (sPAP; HR = 1.12; 95% CI 1.03–1.23; p = 0.008) resulted the only parameters independently associated with PE occurrence. Mortality rates (50% vs 27%; p = 0.010) and cardiogenic shock (37% vs 14%; p = 0.001) were significantly higher in PE as compared with non-PE patients. At multivariate analysis PE was significant associated with mortality. Conclusion PE is relatively common complication in COVID-19 and is associated with increased mortality risk. TAPSE and sPAP resulted the only parameters independently associated with PE occurrence in COVID-19 patients.

In aortic stenosis (AS), the increased afterload results in progressive structural and functional changes that precede the development of symptoms. We hypothesized that the detection of abnormalities in left ventricular long-axis function could identify patients with asymptomatic AS at increased risk of events. We prospectively examined the outcome of 126 patients with asymptomatic AS who underwent a comprehensive echocardiographic examination, including tissue Doppler imaging. B-type natriuretic peptide ( Aortic valve stenosis (AS) is the most common valvular disease and has become the most common cardiovascular disease, after coronary artery disease and hypertension, in developed countries. 1 AS is characterized by a long asymptomatic phase, lasting several decades, during which outflow obstruction progressively develops. 2 Aortic valve replacement is the sole effective therapy for symptomatic patients. In contrast, the management of asymptomatic AS remains controversial. 3,4 In these patients, the chronically increased afterload results in progressive left ventricular (LV) myocardial hypertrophy and interstitial fibrosis, diastolic dysfunction, elevated left atrial pressures, dilation of the left atrium, and, eventually, intrinsic myocardial dysfunction. 5 These structural and functional changes precede symptom development, predict changes in clinical status, and trigger B-type natriuretic peptide (BNP) release. 6,7 In AS, the BNP level correlates with the valve area, diastolic function, functional status, and symptomatic deterioration and might improve risk stratification. 8 -11 Tissue Doppler measurement of mitral annular velocities is a sensitive method for the detection of early abnormalities in LV longaxis function and improves the assessment of LV diastolic function. 12 In asymptomatic AS, the incremental prognostic value of tissue Doppler imaging and BNP measurement compared with validated parameters has never been investigated. The present study was undertaken to prospectively assess the comparative usefulness in predicting the clinical outcomes of long-axis function and BNP level in a series of patients with asymptomatic severe AS. MethodsAsymptomatic patients with severe AS were prospectively screened from our echocardiographic laboratory for inclusion in the present study. All the patients met the following criteria: (1) moderate to severe AS, as defined by an aortic valve area of Յ1.2 cm 2 ; (2) no symptoms according to a careful history taken by the referring physician; (3) normal LV ejection fraction (Ն55%), as calculated by 2-dimensional echocardiography; (4) no more than mild associated cardiac valve lesions; (5) sinus rhythm; and (6) serum creatinine Ͻ16 mg/L. A total of 126 patients met these criteria. The relevant institutional review boards approved the protocol, and all patients gave written informed consent.A comprehensive Doppler echocardiographic study, including M-mode, 2-dimensional echocardiography, color Doppler, and pulsed-wave and continuous-wave Doppler measurements was perform...

Introduction: Little is still known about the prognostic impact of incident arrhythmias in hospitalized patients with COVID-19. The aim of this study was to evaluate the incidence and predictors of sustained tachyarrhythmias in hospitalized patients with COVID-19, and their potential association with disease severity and in-hospital mortality. Materials and methods: This was a retrospective multicenter observation study including consecutive patients with laboratory confirmed COVID-19 admitted to emergency department of ten Italian Hospitals from 15 February to 15 March 2020. The prevalence and the type of incident sustained arrhythmias have been collected. The correlation between the most prevalent arrhythmias and both baseline characteristics and the development of ARDS and in-hospital mortality has been evaluated. Results: 414 hospitalized patients with COVID-19 (66.9 ± 15.0 years, 61.1% male) were included in the present study. During a median follow-up of 28 days (IQR: 12-45), the most frequent incident sustained arrhythmia was AF (N: 71; 17.1%), of which 50 (12.1%) were new-onset and 21 (5.1%) were recurrent, followed by VT (N: 14, 3.4%) and supraventricular arrhythmias (N: 5, 1.2%). Incident AF, both new-onset and recurrent, did not affect the risk of severe adverse events including ARDS and death during hospitalization; in contrast, incident VT significantly increased the risk of in-hospital mortality (RR: 2.55; P: .003). Conclusions: AF is the more frequent incident tachyarrhythmia; however, it not seems associated to ARDS development and death. On the other hand, incident VT is a not frequent but independent predictor of in-hospital mortality among hospitalized COVID-19 patients.

OBJECTIVEImpaired parasympathetic and sympathetic nervous system activity have been demonstrated in patients with diabetes mellitus (DM) and correlated with worse prognosis. Few data are available on the effect of DM on cardiac neuropathy in heart failure (HF). The aim of the current study was to assess cardiac sympathetic activity in HF patients with and without DM.RESEARCH DESIGN AND METHODSPatients with severe HF (n = 75), with (n = 37) and without DM (n = 38), and 14 diabetic patients with normal cardiac function underwent 123I meta-iodobenzylguanidine scintigraphy from which early and late heart-to-mediastinum (H/M) ratios were calculated. Clinical, echocardiographic, and biochemical data were measured.RESULTSDM compared with non-DM patients showed significantly lower early (1.65 ± 0.21 vs. 1.75 ± 0.21; P < 0.05) and late H/M ratios (1.46 ± 0.22 vs. 1.58 ± 0.24; P < 0.03). Early and late H/M were significantly higher in DM patients without HF (2.22 ± 0.35 and 1.99 ± 0.24, respectively) than HF patients with (P < 0.0001) and without (P < 0.0001) DM. In HF patients, an inverse correlation between early or late H/M ratio and hemoglobin A1c (HbA1c) (Pearson = −0.473, P = 0.001; Pearson = −0.382, P = 0.001, respectively) was observed. In DM, in multivariate analysis, HbA1c and ejection fraction remained significant predictors of early H/M; HbA1c remained the only significant predictor of late H/M. No correlation between early or late H/M and HbA1c was found in non-DM patients.CONCLUSIONSDiabetic patients with HF show lower cardiac sympathetic activity than HF patients not having DM or than DM patients with a similar degree of autonomic dysfunction not having HF. HbA1c correlated with the degree of reduction in cardiac sympathetic activity.
