Investigation of Myocardial Protection Level With Specific Cardioplegia Methods in Cardiac Surgery

Investigation of Myocardial Protection Level by Oxidative Stress and Endothelial Damage With Two Cardioplegia Methods Used During Cardiac Surgery

Investigating the myocardial effects of cold blood cardioplegia and del nido cardioplegia solution, which are routinely used in clinical practice, will contribute to the studies in the literature on the safety and efficacy of these two methods.

For this purpose, patients with coronary artery disease that going to be Coronary Artery Bypass Graft (CABG) surgery will be classified within the scope of the SYNTAX score, the level of exposure to cardioplegia change in proportion to their score will be examined. Also, left ventricular muscle mass will be calculated in patients who will undergo Aortic Valve replacement (AVR) due to Aortic Stenosis, and myocardial protection level proportional to muscle mass will be examined, and cardioplegia efficiency will be compared.

Study Overview

Detailed Description

Endocan, E-Selectin, TNF(Tumor Necrosis Factor)-alpha, Total Oxidant and Antioxidant status will be studied on sequential blood samples taken from patients who will undergo Elective Coronary Artery Bypass Grafting operation and aortic valve replacement, via retrograde cardioplegia cannula before induction, at the beginning of cardiopulmonary bypass and after removing the cross-clamp. With routinely used parameters like hemogram, lactate, liver and kidney function tests morbidity-mortality rates for specific cardioplegia technique will be compared

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Del Nido has beneficial effect for Endothelial function
Time Frame: through study completion, an average of 1 year

Two groups with the protection of Del Nido cardioplegia solution, might have lesser Adverse outcomes from cardiopulmonary bypass and cross-clamping irrespectively, with measurements of BLOOD ENDOCAN (ng/ml) and E-SELECTIN LEVELS measured from venous blood specimens.

Endocan and E-selectin levels to be measured by ELISA (ng/ml), expected to be much higher in the blood cardioplegia group because of the protective affect of Del nido cardioplegia.

The venous blood specimens are going to be collected on different operation phases; after cannulation just before the beginning of cardiopulmonary bypass, after removing the cross-clamp before decannulation

through study completion, an average of 1 year
Del Nido cardioplegia solution has lesser oxidative effect comparing to blood cardioplegia
Time Frame: through study completion, an average of 1 year
Two groups with the protection of Del Nido cardioplegia solution, expected to be lesser oxidative affect with comparing of the TOTAL OXIDANT AND ANTIOXIDANT STATUS measured with specific assay kits from venous blood specimens First venous blood specimen will be taken from peripheral blood, 2nd and 3rd will be taken from coronary sinus blood through retrograde cardioplegia cannula; The venous blood specimens are going to be collected on different operation phases: 1st; after cannulation just before the beginning of cardiopulmonary bypass, 2nd; after removing the cross-clamp before decannulation
through study completion, an average of 1 year
SYNTAX effect (SYNergy between PCI{Percutaneous Coronary Intervention} with TAXUS and Cardiac. Surgery)
Time Frame: through study completion, an average of 1 year

The SYNTAX score has the potential to grade coronary anatomy and to guide patient selection toward the optimal revascularisation treatment to treat complex coronary artery disease (CAD).

Subjects with Coronary Artery Disease might have proportional outcomes with SYNTAX score of individuals based upon parameters measured from venous blood specimens That means one wiht the higher SYNTAX score, expected to have higher difference in the blood cardioplegia group compared to Del Nido cardioplegia group because of the lesser protective affects to the myocardium. (ENDOCAN, E-SELECTIN, TOTAL OXIDANT AND ANTIOXIDANT STATUS measured by specific assay kits)

through study completion, an average of 1 year
LVMI effect
Time Frame: through study completion, an average of 1 year

In patients with severe symptomatic Aortic stenosis, concentric left ventricular(LV) geometry and severe LV hypertrophy by echocardiography have been associated with increased mortality after aortic valve replacement. So, demonstration of the relation of LV mass with myocardial protection levels might be important in the aortic stenosis patients for postoperative morbidity and mortality.

Subjects with Aortic Valve Stenosis might have proportional outcomes with Left Ventricular Mass Index (LVMI) of individuals based upon parameters measured from venous blood specimens. (ENDOCAN, E-SELECTIN, TOTAL OXIDANT AND ANTIOXIDANT STATUS measured by specific assay kits)

through study completion, an average of 1 year
