Purpose: We aimed to evaluate the effects of preoperative pulmonary hypertension (PH) on early and long term results in patients undergoing coronary bypass surgery and the effects of coronary bypass surgery on PH.
Methods: Among 2325 patients who underwent elective isolated coronary artery bypass surgery between March 2003 and March 2012, 287 patients with high preoperative pulmonary arterial pressure (PAP) ≥30 mmHg were examined. Patients' data were obtained by retrospective examination of our clinic's database. 69 patients who had complete parameters included in the study.
Results: There was no increase in the New York Heart Association (NYHA) functional classification 84% of cases. Preoperative and postoperative values of the mean ejection fraction and mean PAP of patients was respectively 45.28 ± 9.67 (25-65), 46.03 ±12.4 (20-65) (p = 0.447), 36.67 ± 6.81 (30-60) mmHg, 37.81 ± 10.07 (20-70) mmHg (p = 0.378). The late mortality of cases was 5.79%. In our study, during 33.9 ± 17 (9-100) months follow up period, life expectancy was calculated as 94.7 months.
Conclusion: Preoperative evaluation of these patients for appropriate medical treatment at peroperative and postoperative period, coronary bypass can be performed with low morbidity and mortality rates. In the late period after surgical revascularization PH showed no significant change and had no adverse effect on quality of life.

Postoperative atrial fibrillation following cardiac surgery in severe obesity: the added value of waist circumference.
Int J Obes (Lond)

Institut Universitaire de Cardiologie et de Pneumologie de Québec-Université Laval, Québec, QC, Canada.
Introduction: Obesity is an independent risk factor for postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) surgery. POAF in patients with severe obesity (body mass index [BMI] ≥ 35 kg/m) is less studied. Whether waist circumference (WC) improves prediction of POAF independently of BMI among patients with severe obesity remains unknown.

Introduction: This study aimed to compare the long-term outcomes in a propensity matched population receiving either minimally invasive direct coronary artery bypass (MIDCAB) using left internal thoracic artery (LITA) to the left anterior descending artery (LAD) or percutaneous coronary intervention using second generation everolismus-eluting stents (DES-PCI) in patients treated for isolated proximal LAD stenosis.
Methods: Between January 2012 and December 2017, 421 patients with a nonemergency status undergoing primary isolated proximal LAD revascularization were retrospectively analyzed and were divided into two groups: 111 patients receiving MIDCAB LITA to LAD and 310 patients receiving DES-PCI. Propensity score matching selected 111 pairs and both groups were comparable for all baseline characteristics and well balanced.

Objective: To compare biomarkers of neurovascular unit (NVU) - S100β, NSE, BDNF and indicators of the brain electrical activity in patients who underwent coronary artery bypass grafting (CABG) depending on the use of different versions of multi-tasking cognitive training (CT).
Material And Methods: The study included 89 people, of whom 47 completed the CTI (postural and three cognitive tasks (counting backwards, verbal fluency and the open-ended task «Unusual use of an ordinary object») and 42 patients, who underwent CTII (visuomotor reaction and the same cognitive tasks) in the early postoperative CABG period. The patients of both groups underwent complex testing of psychomotor, executive functions, attention, short-term memory and EEG study in the perioperative period of CABG.
Rare bilateral vascular variations of the upper limb: a cadaveric case study.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

Coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) is associated with the transient activation of a systemic inflammatory response. Fibronectin (FN), an endogenous inflammatory mediator, is a key component of the extracellular matrix. This study aimed to detect changes in cellular and plasma FN levels, as well as its potential fragmentation or FN-fibrin complex formation, in 40 patients undergoing CABG with CPB.
