Pulmonary thromboembolism in coronavirus disease 2019 patients undergoing thromboprophylaxis.

We aimed to investigate the prevalence of pulmonary thromboembolism (PTE) and its association with clinical variables in a cohort of hospitalized coronavirus disease 2019 (COVID-19) patients receiving low-molecular-weight heparin (LMWH) at prophylactic dosage.In this retrospective observational study we included COVID-19 patients receiving prophylactic LMWH from admission but still referred for lower-limbs venous Doppler ultrasound (LL-US) and computed tomography pulmonary angiography (CTPA) for clinical PTE suspicion. A dedicated radiologist reviewed CTPA images to assess PTE presence/extension.

Non-Overt Coagulopathy in Non-ICU Patients with Mild to Moderate COVID-19 Pneumonia.

Introduction: Aim of the study is to assess the occurrence of early stage coagulopathy and disseminated intravascular coagulation (DIC) in patients with mild to moderate respiratory distress secondary to SARS-CoV-2 infection.

Materials And Methods: Data of patients hospitalized from 18 March 2020 to 20 April 2020 were retrospectively reviewed. Two scores for the screening of coagulopathy (SIC and non-overt DIC scores) were calculated.

Long-term results of sequential vein coronary artery bypass grafting compared with totally arterial myocardial revascularization: a propensity score-matched follow-up study†.

Objectives: The aim of the study was to analyse the early and long-term outcomes of a consecutive series of patients who underwent sequential coronary artery bypass grafting (CABG) and to compare them with a matched population of totally arterial revascularized patients.

Methods: From January 1994 to December 1996, 209 patients underwent total arterial myocardial revascularization at our institution [arterial (ART) group]. In the same period, 2097 patients underwent CABG with left internal thoracic artery on left anterior descending and great saphenous vein on the right and circumflex branches sequentially [sequential vein (SV) group].

Interleukin-15 and soluble interleukin-15 receptor α in coronary artery disease patients: association with epicardial fat and indices of adipose tissue distribution.

Interleukin-15 (IL-15) is a pro-inflammatory cytokine which signals via a specific alpha receptor subunit (IL-15Rα). Increased IL-15 level has been observed in cardiovascular patients and IL-15 immunoreactivity has been detected at vulnerable atherosclerotic plaques. Due to the association between adipose tissue distribution, inflammation and coronary artery disease (CAD), we quantified IL-15 and IL-15Rα in CAD patients with different adiposity and adipose tissue distribution and we evaluated whether epicardial adipose tissue (EAT), a visceral fat depot surrounding and infiltrating myocardium, may be a source of both molecules.

The additional prognostic value of left atrial volume on the outcome of patients after surgical ventricular reconstruction.

Background: Left atrial volume (LAV) is a powerful predictor of outcome in patients with chronic heart failure (HF). It is unknown whether LAV provides additional prognostic information in patients undergoing surgical ventricular reconstruction (SVR). Our objective was to assess the prognostic power of LAV on survival in patients with HF after undergoing SVR.

Optimizing dose and administration regimen of a high-relaxivity contrast agent for myocardial MRI late gadolinium enhancement.

Objectives: To investigate the time-course of late gadolinium enhancement of infarcted myocardium using gadobenate dimeglumine at different dosages and administration regimens.

Materials And Methods: After institutional review board approval and informed consent, we studied 13 patients (aged 63±11 years) with chronic myocardial infarction. They underwent two gadobenate dimeglumine-enhanced MR examinations (interval 24-48 h) using short-axis inversion-recovery gradient-echo sequences, with the following two different protocols, in randomized order: 0.

Surgical ventricular restoration: left ventricular shape influence on cardiac function, clinical status, and survival.

Background: Myocardial infarction can result in a spectrum of left ventricular (LV) shape abnormalities. Surgical ventricular restoration (SVR) can be applied to any, but there are no data that relate its effectiveness to LV shape. Moreover, there is no consensus on the benefit of SVR in patients with a markedly dilated ventricle, without clear demarcation between scarred and normal tissue.
