Lymphocyte Levels and Morbidity and Mortality in Cardiovascular Surgery With Cardiopulmonary Bypass.

Introduction: A year ago, in a sample of 113 patients, our research group found that a high number of lymphocytes in the immediate postoperative period was correlated to a poor prognosis in cardiovascular surgeries. This study is an expansion of the initial study in order to confirm this finding.

Methods: We analyzed the data of 338 consecutive patients submitted to cardiovascular surgeries with cardiopulmonary bypass performed at Hospital Universitário Ciências Médicas (Belo Horizonte/Brazil) from 2015 to 2017.

Impact of body mass index on outcome in patients undergoing coronary artery bypass grafting and/or valve replacement surgery.

Objective: This study aimed to analyze the impact of body mass index on outcomes of 101 patients undergoing coronary artery bypass grafting, valve replacement, or combined valve/ coronary artery bypass grafting surgery in a private hospital in Belo Horizonte, Brazil.

Methods: This was a prospective cross-sectional study of patients undergoing cardiac surgery from May 2009 to December 2012. All patients were followed up from the first day of admission until discharge or death.

Comparison of patency between radial artery and saphenous vein in a coronary artery bypass grafting post operative with return of the symptoms.

Objective: To compare the radial artery and saphenous vein's patency in patients with recurrence of symptoms in a coronary artery bypass grafting (CABG).

Methods: Retrospective study. From January 1998 to December 2005, 469 CABGs were performed using the radial artery as a graft, in Vera Cruz Hospital in Belo Horizonte/ MG.

Hemodinamic behavior of arterial anastomosis using fibrin sealant: experimental study in swine.

Objectives: To evaluate the flow, tear pressure, the need of reinforcement stitches in sutured arteries reinforced or not using fibrin sealant after a cross-section.

Method: Tissucol fibrin sealant was used. The femoral and carotid arteries of seventeen swine from the same breed (weighing from 15 to 20 kg) were cross-sectioned after heparinization and subjected to anastomoses using a single continuous plane of prolene 7-0.
