Background: The aim of this large retrospective study was to provide a logistic risk model along an additive score to predict early mortality after surgical treatment of patients with heart valve or prosthesis infective endocarditis (IE).

Methods: From 2000 to 2015, 2715 patients with native valve endocarditis (NVE) or prosthesis valve endocarditis (PVE) were operated on in 26 Italian Cardiac Surgery Centers. The relationship between early mortality and covariates was evaluated with logistic mixed effect models.

Objectives: We described clinical-epidemiological features of prosthetic valve endocarditis (PVE) and assessed the determinants of early surgical outcomes in multicentre design.

Methods: Data regarding 2823 patients undergoing surgery for endocarditis at 19 Italian Centers between 1979 and 2015 were collected in a database. Of them, 582 had PVE: in this group, the determinants of early mortality and complications were assessed, also taking into account the different chronological eras encompassed by the study.

Objectives: Although commonly reported as single-centre experiences, redo aortic valve replacement (RAVR) has overall acceptable results. Nevertheless, trans-catheter aortic valve replacement has recently questioned the efficacy of RAVR.

Methods: Early-to-mid-term results and determinants of mortality in 711 cases of RAVR from seven European institutions were assessed in the entire population and in selected high-risk subgroups [elderly >75 years, urgent/emergent procedures, preoperative New York Heart Association (NYHA) functional Class IV and endocarditis].

Background: Octogenarians undergoing surgical aortic valve replacement (AVR) after prior cardiac surgery are expected to be at high risk of adverse events. This finding has recently popularized transcatheter AVR in this cohort.

Methods: This multicenter study includes 744 patients (99 were 80 years or older) who underwent surgical AVR after prior cardiac surgery.

Aims: We analyzed the effects of tight glycemic control on regenerative potential of myocardium during acute myocardial infarction.

Patients And Methods: Seventy-five patients with their first acute myocardial infarction undergoing coronary bypass surgery were studied: 25 patients with glycemia below 140 mg/dl served as the control group; hyperglycemic patients (glucose>140 mg/dl) were randomized to intensive glycemic control (IGC; n=20; glucose goal, 80-140 mg/dl), conventional glycemic control (CGC; n=20; glucose goal, 180-200 mg/dl), or glucose-insulin-potassium (GIK; n=10; glucose goal, 180-200 mg/dl) for almost 3 d before surgery, using insulin infusion followed by sc insulin treatment. During surgery, myocyte precursor cells (MPC) (c-kit/MEFC2/GATA4-positive cells), oxidation of MPC DNA (c-kit/8-hydroxydeoxyguanosine-positive cells), senescent MPC (c-kit/p16INK4a-positive cells), and cycling cardiomyocytes (Ki-67-positive cells) were analyzed in biopsy specimens taken from the peri-infarcted area.

Context: Several investigations as well as prospective studies have shown a significant correlation between glucose metabolism and atherosclerosis in patients without diabetes, but differences in parameters of glucose metabolism among the various degrees of coronary disease in such patients have not been specifically evaluated.

Objective: To investigate glucose metabolism in patients with normal glucose tolerance (NGT) and coronary heart disease (CHD).

Design, Setting, And Participants: Cross-sectional study of 234 men (mean [SD] age, 56.
