Background: Increase in the concentration of homocysteine is one of the risks of cardiovascular diseases. Coronary artery disease accompanied the increase of LDL cholesterol level and hipolipemic drugs are used in such treatments. Also these drugs have pleiotropic effects, which are not greatly known. The aim of that study is to compare the effect of three different hipolipemic therapies (rosuvastatin 15mg/d; atorvastatin 40mg/d; atorvastatin+ezetymibe 10mg/d+10mg/d) depending upon the concentration of homocysteine and lipid peroxidation in plasma of CAD patients with non-target LDL-cholesterol level.
Methods And Results: The study involved 30 healthy subjects as well as 30 patients with angiographically confirmed coronary artery disease who despite at least 6 months hypolipidemic treatment did not achieve LDL-C <70mg/dl. The following parameters studied included homocysteine level, lipid peroxidation in plasma and lipidogram parameters. Our study showed increase of homocysteine level, lipid peroxidation in plasma, LDL-C concentration and total cholesterol level. After six months therapy, the following changes were observed in comparison to the values before therapy: decrease of homocysteine level in plasma - R15 20%, A40 26% and A+E 28%; decrease of lipid peroxidation in plasma - R15 31%, A40 27% and A+E 32%; decrease of LDL-C cholesterol level - R15 18%; A40 17% and A+E 33% and decrease of total cholesterol level - R15 9%, A40 15% and A+E 17%.
Conclusion: Our results suggest that intensive lipid-lowering therapy has a beneficial effect on certain parameters of the blood of CAD patients.

Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of morbidity and mortality globally, significantly influenced by modifiable risk factors, particularly hypercholesterolemia. Despite the availability of effective lipid-lowering drugs, achieving the low-density lipoprotein cholesterol (LDL-C) target levels remains a significant challenge in clinical practice, contributing to persistent high rates of cardiovascular events. The intEgrated multidiscipliNary pathway for large-scale maNagement of dyslipidemiA in high-risk patients (ENNA) Project was designed to address the alarming rates of suboptimal lipid management among high and very-high risk patients in the Province of Enna, Sicily.

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.

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.
