RESUMO
OBJECTIVE: This study evaluated the relationship between the amount of urinary output during cardiopulmonary bypass and acute kidney injury in the postoperative period of coronary artery bypass grafting. METHODS: Two hundred patients with normal preoperative serum creatinine levels, operated on with isolated CABG between 2012-2014 were investigated retrospectively. The RIFLE (Risk, injury, failure, loss of function, and end-stage renal disease) risk scores were calculated for each patient in the third postoperative day. Patients were distributed into two groups in relation to the presence of acute kidney injury or not and these two groups were compared. RESULTS: The urinary output (mL/kg/hour) during cardiopulmonary bypass in the acute kidney injury negative group was significantly higher than in the acute kidney injury positive group (P = .022). In case of a urinary output value 3.70 and lower to predict acute kidney injury positivity, sensitivity was detected as 71.43%. Results of the analysis for urinary output predict positivity of acute kidney injury. CONCLUSION: We suggest that urine output during cardiopulmonary bypass is a significant criteria that could predict acute kidney injury following coronary artery bypass grafting with cardiopulmonary bypass. Attempts to increase the urine output during cardiopulmonary bypass could help to maintain the renal functions during and after surgery.

Pulmonary agenesis is associated with the absence of pulmonary vessels, bronchi, or parenchyma. This condition usually occurs between the 4th and 5th week of gestation during the embryonic phase. Etiopathogenic factors associated with pulmonary agenesis are not fully understood. In the literature, genetic and teratogenic factors, viral infections, and vitamin-A deficiency are shown to be associated with pulmonary agenesis [Malcon 2012]. This condition may be seen unilaterally or bilaterally. Although the precise rate of incidence is unknown, it is estimated to occur in one of every 10,000 to 12,000 live births [Yetim 2011]. There is a 1.3:1 female predominance with unilateral agenesis [Halilbasic 2013].

OBJECTIVE: To investigate the association of platelet to lymphocyte ratio to mortality and morbidity after coronary artery bypass grafting operation. METHODS: We evaluated records of 916 patients who underwent coronary artery bypass grafting operation between January 2009 and May 2014 retrospectively. Patients were grouped as Group 1 (n = 604) if the platelet to lymphocyte ratio was above 142 and Group 2 (n = 312) if platelet to lymphocyte ratio was below 142. RESULTS: The number of patients who developed a neurologic event during the hospital stay and in the first postoperative month was 7 (1.2%) in Group 1 and 12 (3.8%) in Group 2 for which the difference was statistically significant (P = .007). Early term mortality occurred in 3 patients (0.5%) in Group 1 and in 10 patients (3.2%) in Group 2 for which the difference was statistically highly significant (P = .001). In univariate and multivariate regression analysis, the preoperative platelet to lymphocyte ratio was determined as an independent risk factor for occurrence of atrial fibrillation in the early postoperative period, reoperation for sternum dehiscence, occurrence of a neurologic event, prolonged stay in the hospital and mortality. CONCLUSION: In this study, elevated levels of platelet to lymphocyte ratio were associated with mortality and morbidity after coronary artery bypass grafting operation.

BACKGROUND: Treatment method in patients with coronary artery disease undergoing coronary bypass surgery with accompanying carotid artery disease is still a hot topic among clinicians. This study is designed to investigate if there is an effect on myocardial infarction, cerebrovascular events and mortality during postoperative period of simultaneous carotid endarterectomy with coronary bypass surgery compared to staged carotid artery stenting before coronary bypass surgery. METHODS: 102 patients (79 male, 23 female) who underwent simultaneous carotid endarterectomy with coronary bypass surgery or staged carotid artery stenting with coronary bypass surgery in the same center with the same surgical team were divided into 2 groups and retrospectively reviewed. Group 1 (n = 71) had coronary artery bypass surgery under general anesthesia with carotid endarterectomy followed by cardiopulmonary bypass with heart team decision. Again with heart team decision, Group 2 (n=31), patients at high-risk for carotid endarterectomy (serious cardiac disease, severe chronic obstructive pulmonary disease, superiorly located lesions), received carotid artery stents in the interventional radiology department and a month later, coronary bypass surgery was performed with cardiopulmonary bypass under elective conditions. RESULTS: Median of patient age was 67.5 (45-83) years. Twenty-two patients (31%) in Group 1 and 19 patients (56.3%) in Group 2 had neurological symptoms, which was statistically significant (P = .004). During the early postoperative term, three patients (4.2%) in Group 1 and two patients (6.5%) in Group 2 died (P = .64). Five patients (7.0%) in Group 1 and two patients (6.5%) in Group 2 developed neurological symptoms during the early postoperative term (P > .05). Likewise, two patients (2.8%) in Group 1 and five patients (16.1%) in Group 2 developed myocardial infarction following carotid intervention (P = .03). CONCLUSIONS: In patients with significant carotid artery stenosis undergoing coronary bypass surgery with cardiopulmonary bypass, in comparison to simultaneous carotid endarterectomy with coronary bypass technique and carotid artery stenting followed with coronary bypass technique showed no difference in combined endpoint (postoperative myocardial infarction, neurological events, and mortality). With proper tools and according to the decisions made by heart teams, both management strategies can be safely performed.

Background: In this study, we aimed to evaluate primary outcomes and main characteristics of emergency and elective/urgent cardiovascular surgeries which were performed in the first three months of the novel coronavirus disease 2019 (COVID-19) pandemic in our center. Methods: Between March 11th, 2020 and June 11th, 2020, a total of 209 patients (44 males, 165 females; mean age: 57.3±12.8 years; range, 20 to 80 years) who underwent emergency or elective/urgent surgery with cardiovascular pathologies were retrospectively analyzed. The patients were classified as emergency and elective/urgent according to the level of necessity of the surgical procedure at the time of hospital admission. Pre-, intra-, and postoperative data of the patients were recorded. Results: During the study period, 156 elective/urgent and 74 emergency cardiovascular surgeries were performed. Six COVID-19 (+) patients were operated emergently. The number of acute aortic dissection and peripheral vascular surgery was higher in the emergency group (p<0.05). Two patients who were COVID-19 (-) preoperatively became COVID-19 (+) in the postoperative period. In these patients, acute respiratory distress syndrome developed, and extracorporeal membrane oxygenation support was needed. Four patients who needed post-cardiotomy extracorporeal membrane oxygenation support due to low cardiac output were COVID-19 (-) both in the pre- and postoperative periods. The overall in-hospital mortality rate was 9.1%. Conclusion: Even during pandemic such as COVID-19, referral centers with experienced personnel can provide non-pandemic healthcare with a quality close to the daily routine.
RESUMO
Papillary muscle rupture (PMR) is a significant mechanical complication following myocardial infarction (MI), a condition associated with a high mortality. It results in severe mitral valve regurgitation (MR), often accompanied by cardiogenic shock and pulmonary edema, requiring both emergent medical treatment and surgical intervention. Surgical treatment includes either chordal sparing mitral valve replacement or mitral valve repair, which is associated with a high mortality. Mitral valve repair is believed to be superior to mitral valve replacement with respect to improving left ventricular function, albeit with risk of repair failure and resulting in increased cross clamp times. Concomitant coronary revascularization may improve both short- and long-term outcomes after surgery. With advances in medical innovations in the field of transcatheter devices, these devices may serve as a bridge to recovery or treatment in the setting of acute MR due to PMR. However, long-term data will be required to establish the non-inferiority of one treatment modality over the other. Management of these patients should be guided by a dedicated mitral heart team.
RESUMO
Minimally invasive tricuspid surgery using a complete endoscopic approach has a steep learning curve. The purpose of creating the suture map is to allow placement of sutures with minimal tissue handling and to improve operating efficiency. This process is useful for surgeons who are just beginning to learn minimally invasive surgery and are at an early stage of their endoscopic surgical career.

Background: This study aims to investigate the association of progression of tricuspid regurgitation following double-valve replacement by comparing the tricuspid valve repair and no repair groups, and to analyze outcomes of patients with non-repaired mild-to-moderate tricuspid regurgitation. Methods: Between January 2014 and September 2017, a total of 157 patients (74 males, 83 females; mean age: 51.7±13.7 years; range, 18 to 78 years) who underwent aortic and mitral valve replacements with/without concomitant tricuspid valve repair were retrospectively analyzed. The patients were divided into two groups: no-repair (n=78) and repair groups (n=79). The primary outcome measure was development of more than moderate tricuspid regurgitation during follow-up. Results: The data were evaluated according to propensity score matched analysis. The progression of tricuspid regurgitation was significantly increased in the no-repair group (p=0.006). Rheumatic etiology was independently associated with the presence of postoperative moderateto- severe tricuspid regurgitation (p=0.004, odds ratio: 3.40). There was no statistically significant difference between the groups in terms of the potential complications and mortality and survival rates. A multivariable subgroup analysis for the baseline mild-to-moderate tricuspid regurgitation without repair showed that rheumatic etiology was an independent factor for the progression of postoperative tricuspid regurgitation (p=0.01). Conclusion: Our study results demonstrated that rheumatic etiology was an independent marker for increased tricuspid regurgitation and it was also independently associated with increased tricuspid regurgitation in patients with mild-to-moderate non-repaired patients. The degree of tricuspid regurgitation was improved in the repair group during follow-up.
RESUMO
INTRODUCTION: In this trial, we initially aimed to investigate the major predictive factors for prolonged mechanical ventilation (PMV) following cardiac surgery with cardiopulmonary bypass (CPB) in our center and, secondarily, we tried to find out the effects of the independent factors on mortality. METHODS: Between July 2017 and August 2018, 207 patients who underwent cardiac surgery with CPB were retrospectively investigated. The patients were randomly divided into two subgroups according to the duration of ventilator dependence (group 1 <24 hours, n=164, 79%; group 2 >24 hours, n=43, 21%). RESULTS: 207 patients (mean age 59.47±10.56) who underwent cardiac surgery with CPB were enrolled in this study (n=145, 70% of male patients; n=62, 30% of female patients). Amid these patients, 43 (n=43, 20.77%) had prolonged intubation time. After multivariate logistic regression analysis among preoperative factors, female gender (OR=2.321, P=0.028), leukocytosis (OR=1.233, P=0.006), perioperative lactate level (OR=1.224, P=0.027), CPB time (OR=1.012, P=0.012) and postoperative revision for bleeding (OR=23.125, P=0.040) were significantly detected. The effect of predictive factors on mortality after cardiac surgery was determined and found that PMV did not affect hospital mortality (OR=1.979, P=0.420). CONCLUSION: In our report, we revealed, differently from previous studies, that intraoperative lactate levels which manifest organ perfusion and oxygenation were included and were significantly different in the early extubation group compared to the PMV group. Female gender, preoperative leukocytosis, intraoperative CPB time, lactate levels and postoperative revision for bleeding were the independent predictive factors for PMV. Moreover, PMV did not affect the early-term mortality during hospital stay.

OBJECTIVE: Acute kidney injury (AKI) is one of the most important complications after coronary artery bypass grafting (CABG) procedure. Serum albumin, which is an acute phase reactant, is suggested to be associated with AKI development subsequent to various surgical procedures. In this study, we research the relation between preoperative serum albumin levels and postoperative AKI development in diabetes mellitus (DM) patients undergoing isolated CABG. METHODS: We included a total of 634 diabetic patients undergoing CABG (60.5±9.1 years, 65.1% male) into this study, which was performed between September 2009 and January 2014 in a single center. The relation between preoperative serum albumin levels and postoperative AKI development was observed. AKI was evaluated and diagnosed using the Kidney Disease: Improving Global Outcomes (KDIGO) classification. RESULTS: AKI was diagnosed in 230 (36.3%) patients. Multiple logistic regression analysis was performed to determine the independent predictors of AKI development. Proteinuria (odds ratio [OR] and 95% confidence interval [CI], 1.066 [1.002-1.135]; P=0.043) and low preoperative serum albumin levels (OR and 95% CI, 0.453 [0.216-0.947]; P=0.035) were found to be independent predictors of AKI. According to the receiver operating characteristic curve analysis, albumin level <3mg/dL (area under the curve: 0.621 [0.572-0.669], P<0.001) had 83% sensitivity and 10% specificity on predicting the development of AKI. CONCLUSION: We observed that a preoperative low serum albumin level was associated with postoperative AKI development in patients with DM who underwent isolated CABG procedure. We emphasize that this adjustable albumin level should be considered before the operation since it is an easy and clinically implementable management for the prevention of AKI development.

BACKGROUND: This study aims to investigate the effect of time interval between coronary angiography and coronary artery bypass grafting surgery on postoperative acute kidney injury in patients with diabetes mellitus. METHODS: Between December 2013 and November 2016, a total of 421 diabetic patients (274 males, 147 females; mean age 60±9.2 years; range, 31 to 84 years) who underwent coronary artery bypass grafting were included in the study. Data including demographic characteristics of the patients, comorbidities, medical, and surgical histories, previous coronary angiographies, and operative and laboratory results were retrospectively analyzed. The patients were divided into two groups as those with acute kidney injury (n=108) and those without acute kidney injury (n=313). The Risk, Injury, Failure, Loss, End-Stage Kidney Disease (RIFLE) criteria were used to define acute kidney injury. The patients were further classified into three subgroups according to the time interval: 0-3 days, 4-7 days, and >7 days. RESULTS: There was no statistically significant difference in the median time between coronary angiography and coronary artery bypass grafting between the patients with and without acute kidney injury (11.5 and 12.0 days; respectively p=0.871). There was no significant difference in the risk factors for acute kidney injury among the subgroups. Multivariate analysis revealed that previous myocardial infarction (odds ratio [OR]: 5.192, 95% confidence interval [CI]: 2.176-12.38; p<0.001) and the increase in the creatinine levels in the first postoperative day (OR: 4.102 and 95% CI: 1.278- 13.17; p=0.018) were independent predictors of acute kidney injury. CONCLUSION: Coronary artery bypass grafting can be performed without any delay after coronary angiography without an increase in the postoperative risk of acute kidney injury in patients with diabetes mellitus.
RESUMO
BACKGROUND: In this study, we aimed to present our results of mitral valve repair. METHODS: Between January 2007 and November 2016, a total of 128 patients (72 males, 56 females; mean age 51.8±17.2 years; range 16 to 84 years) who underwent mitral valve repair in our heart center were retrospectively analyzed. There were mitral regurgitation in 86.7% (n=111), mitral stenosis in 7.8% (n=10), and mixed type valve disease in 5.5% of the patients (n=7). Mitral ring annuloplasty was performed in 80.5% (n=103), implantation of the artificial chordae in 36.7% (n=47), open mitral commissurotomy in 13.3% (n=17), and Alfieri procedure in 6.3% (n=8) of the patients. Sixty-two patients (48.8%) underwent isolated mitral valve repair, while concomitant surgical procedures were performed in the remaining patients. Postoperative mean follow-up was 52 months. RESULTS: Early (30-day) mortality was observed in seven patients due to low cardiac output. There was no mid-term mortality. During follow-up, various degree of mitral regurgitation was detected in 4 patients (3.6%), regurgitation was severe in two of them and these two require reoperation with the replacement of the valve. Patients with a myxomatous valve pathology who underwent isolated valve repair most benefited from valve repair. Patients with isolated mitral stenosis were the most successful group among the patients with a rheumatic etiology. Postoperative echocardiography showed a significant decrease in the left atrial diameter and pulmonary artery systolic pressures (p<0.01). CONCLUSION: Mitral valve repair can be applied as an effective and safe treatment method in patients in whom the mitral valve anatomy is sufficient for repair. We suggest that each patient with mitral valve pathology should be evaluated in terms of reparability.
RESUMO
INTRODUCTION:: Elevated hemoglobin A1c levels in patients with diabetes mellitus have been known as a risk factor for acute kidney injury after coronary artery bypass grafting. However, the relationship between hemoglobin A1c levels in non-diabetics and acute kidney injury is under debate. We aimed to investigate the association of preoperative hemoglobin A1c levels with acute kidney injury in non-diabetic patients undergoing isolated coronary artery bypass grafting. METHODS:: 202 non-diabetic patients with normal renal function (serum creatinine <1.4 mg/dl) who underwent isolated coronary bypass were analyzed. Hemoglobin A1c level was measured at the baseline examination. Patients were separated into two groups according to preoperative Hemoglobin A1c level. Group 1 consisted of patients with preoperative HbA1c levels of < 5.6% and Group 2 consisted of patients with preoperative HbA1c levels of ≥ 5.6%. Acute kidney injury diagnosis was made by comparing baseline and postoperative serum creatinine to determine the presence of predefined significant change based on the Kidney Disease Improving Global Outcomes (KDIGO) definition. RESULTS:: Acute kidney injury occurred in 19 (10.5%) patients after surgery. The incidence of acute kidney injury was 3.6% in Group 1 and 16.7% in Group 2. Elevated baseline hemoglobin A1c level was found to be associated with acute kidney injury (P=0.0001). None of the patients became hemodialysis dependent. The cut off value for acute kidney injury in our group of patients was 5.75%. CONCLUSION:: Our findings suggest that, in non-diabetics, elevated preoperative hemoglobin A1c level may be associated with acute kidney injury in patients undergoing coronary artery bypass grafting. Prospective randomized studies in larger groups are needed to confirm these results.

BACKGROUND: This study was designed to determine the short- and long-term effects of proximal aortic anastomosis, performed during isolated coronary artery bypass grafting (CABG) in patients with dilatation of the ascending aorta who did not require surgical intervention. METHODS: The study was performed on 192 (38 female and 160 male patients; mean age, 62.1 ± 9.2 years; range, 42-80 years) patients with dilatation of the ascending aorta who underwent CABG surgery between 1 June 2006 and 31 May 2014. In group 1 (n = 114), the saphenous vein and left internal mammarian artery grafts were used, and proximal anastomosis was performed on the ascending aorta. In group 2 (n = 78), left and right internal mammarian artery grafts were used, and proximal aortic anastomosis was not performed. Pre-operatively and in the first and third years postoperatively, the ascending aortic diameter was measured and recorded using transthoracic echocardiography at four different regions (annulus, sinus of Valsalva, sinotubular junction and tubular aorta). RESULTS: A statistically significant difference was found between the groups for the number of grafts used and the duration of aortic cross-clamping and cardiopulmonary bypass. No significant intergroup difference was seen for the mean diameter of the ascending aorta (p > 0.05). Annual changes in the aortic diameter were found to be extremely significantly different in both groups (p = 0.0001). Mean values of the aortic diameter at the level of the sinotubular junction and tubular ascending aorta, mean aortic diameters (p = 0.002 and p = 0.0001, respectively), annual increase in diameter (p = 0.0001 and p = 0.0001, respectively), and mean annual difference in diameter (p = 0.0001 and p = 0.0001, respectively) at one and three years postoperatively were statistically significantly different between the groups. CONCLUSION: In patients with ascending aortic dilatation who did not require surgical intervention and who had proximal anastomosis of the ascending aorta and underwent only CABG, we detected statistically significant increases in the diameter of the sinotubular junction and tubular aorta up to three years postoperatively.

INTRODUCTION: Atrial fibrillation (AF) after coronary artery bypass grafting (CABG) operation is associated with increased risk of prolonged hospitalisation, health expenses and adverse clinical outcomes. AIM: To investigate the relationship of atrial fibrillation after an isolated coronary artery bypass operation with levels of mean platelet volume and C-reactive protein. MATERIAL AND METHODS: Among 1240 patients who underwent operations for isolated coronary artery bypass grafting with cardiopulmonary bypass between January 2007 and May 2014, 1138 (91.8%) patients with preoperative normal sinusal rhythm were enrolled in the study. Patients were assigned to group 1 (n = 294) comprising patients who developed atrial fibrillation in the first 72 postoperative hours or group 2 (n = 844) comprising patients who remained in normal sinusal rhythm in the postoperative period. RESULTS: The incidence of postoperative atrial fibrillation was 25.8%. The preoperative mean platelet volume (fl) and C-reactive protein (mg/dl) values in group 1 were 9.1 ±0.5 and 1.1 ±0.9 respectively, while these values were 8.3 ±0.6 and 0.5 ±0.3 respectively in group 2, which was statistically significant (p = 0.0001). Length of stay in the hospital (p = 0.0001) was higher in group 1. The values of mean platelet volume (fl) and mean C-reactive protein (mg/dl) were 9.9 ±0.9 and 30.9 ±3.4 respectively in group 1, while the values of mean platelet volume (fl) and mean C-reactive protein (mg/dl) were 8.8 ±0.6 and 24.9 ±4.8 respectively in group 2 (p = 0.0001 for mean platelet volume, p = 0.0001 for C-reactive protein). The difference between the groups was statistically significant in terms of postoperative neurologic events (p = 0.0001) and hospital mortality (p = 0.001). Increased C-reactive protein and mean platelet volume levels were found to be independent predictors of postoperative atrial fibrillation. CONCLUSIONS: In our study, elevated preoperative mean platelet volume and C-reactive protein levels were associated with development of postoperative atrial fibrillation.
RESUMO
Abstract Introduction: In this trial, we initially aimed to investigate the major predictive factors for prolonged mechanical ventilation (PMV) following cardiac surgery with cardiopulmonary bypass (CPB) in our center and, secondarily, we tried to find out the effects of the independent factors on mortality. Methods: Between July 2017 and August 2018, 207 patients who underwent cardiac surgery with CPB were retrospectively investigated. The patients were randomly divided into two subgroups according to the duration of ventilator dependence (group 1 <24 hours, n=164, 79%; group 2 >24 hours, n=43, 21%). Results: 207 patients (mean age 59.47±10.56) who underwent cardiac surgery with CPB were enrolled in this study (n=145, 70% of male patients; n=62, 30% of female patients). Amid these patients, 43 (n=43, 20.77%) had prolonged intubation time. After multivariate logistic regression analysis among preoperative factors, female gender (OR=2.321, P=0.028), leukocytosis (OR=1.233, P=0.006), perioperative lactate level (OR=1.224, P=0.027), CPB time (OR=1.012, P=0.012) and postoperative revision for bleeding (OR=23.125, P=0.040) were significantly detected. The effect of predictive factors on mortality after cardiac surgery was determined and found that PMV did not affect hospital mortality (OR=1.979, P=0.420). Conclusion: In our report, we revealed, differently from previous studies, that intraoperative lactate levels which manifest organ perfusion and oxygenation were included and were significantly different in the early extubation group compared to the PMV group. Female gender, preoperative leukocytosis, intraoperative CPB time, lactate levels and postoperative revision for bleeding were the independent predictive factors for PMV. Moreover, PMV did not affect the early-term mortality during hospital stay.

A 62-year-old man presented to the cardiology clinic with symptoms of fatigue, shortness of breath and swelling in the abdomen and legs. A pedunculated mobile mass with a short stalk in the right atrium was found to originate from the inferior vena caval opening and prolapse into the right ventricle through a tricuspid valve during diastole in echocardiography. The patient was referred to our department and surgery was planned for right atrial myxomas diagnosis. The mass with surrounding tissue was surgically removed using the cardiopulmonary bypass method. No postoperative complications were seen in the currently asymptomatic patient who is still under our follow-up schedule.

Abstract Objective: Acute kidney injury (AKI) is one of the most important complications after coronary artery bypass grafting (CABG) procedure. Serum albumin, which is an acute phase reactant, is suggested to be associated with AKI development subsequent to various surgical procedures. In this study, we research the relation between preoperative serum albumin levels and postoperative AKI development in diabetes mellitus (DM) patients undergoing isolated CABG. Methods: We included a total of 634 diabetic patients undergoing CABG (60.5±9.1 years, 65.1% male) into this study, which was performed between September 2009 and January 2014 in a single center. The relation between preoperative serum albumin levels and postoperative AKI development was observed. AKI was evaluated and diagnosed using the Kidney Disease: Improving Global Outcomes (KDIGO) classification. Results: AKI was diagnosed in 230 (36.3%) patients. Multiple logistic regression analysis was performed to determine the independent predictors of AKI development. Proteinuria (odds ratio [OR] and 95% confidence interval [CI], 1.066 [1.002-1.135]; P=0.043) and low preoperative serum albumin levels (OR and 95% CI, 0.453 [0.216-0.947]; P=0.035) were found to be independent predictors of AKI. According to the receiver operating characteristic curve analysis, albumin level <3mg/dL (area under the curve: 0.621 [0.572-0.669], P<0.001) had 83% sensitivity and 10% specificity on predicting the development of AKI. Conclusion: We observed that a preoperative low serum albumin level was associated with postoperative AKI development in patients with DM who underwent isolated CABG procedure. We emphasize that this adjustable albumin level should be considered before the operation since it is an easy and clinically implementable management for the prevention of AKI development.

Abstract INTRODUCTION: Elevated hemoglobin A1c levels in patients with diabetes mellitus have been known as a risk factor for acute kidney injury after coronary artery bypass grafting. However, the relationship between hemoglobin A1c levels in non-diabetics and acute kidney injury is under debate. We aimed to investigate the association of preoperative hemoglobin A1c levels with acute kidney injury in non-diabetic patients undergoing isolated coronary artery bypass grafting. METHODS: 202 non-diabetic patients with normal renal function (serum creatinine <1.4 mg/dl) who underwent isolated coronary bypass were analyzed. Hemoglobin A1c level was measured at the baseline examination. Patients were separated into two groups according to preoperative Hemoglobin A1c level. Group 1 consisted of patients with preoperative HbA1c levels of < 5.6% and Group 2 consisted of patients with preoperative HbA1c levels of ≥ 5.6%. Acute kidney injury diagnosis was made by comparing baseline and postoperative serum creatinine to determine the presence of predefined significant change based on the Kidney Disease Improving Global Outcomes (KDIGO) definition. RESULTS: Acute kidney injury occurred in 19 (10.5%) patients after surgery. The incidence of acute kidney injury was 3.6% in Group 1 and 16.7% in Group 2. Elevated baseline hemoglobin A1c level was found to be associated with acute kidney injury (P=0.0001). None of the patients became hemodialysis dependent. The cut off value for acute kidney injury in our group of patients was 5.75%. CONCLUSION: Our findings suggest that, in non-diabetics, elevated preoperative hemoglobin A1c level may be associated with acute kidney injury in patients undergoing coronary artery bypass grafting. Prospective randomized studies in larger groups are needed to confirm these results.
