RESUMEN

BACKGROUND: Right ventricular (RV) dysfunction may develop over the course of chronic obstructive pulmonary disease (COPD) and is an important predictor of morbidity and mortality. Polymorphism of the multidrug resistance-1 (MDR-1) gene has been correlated with worse clinical findings among patients with COPD. Our aim here was to investigate the relationship between MDR-1 C3435T gene polymorphism and RV dysfunction in COPD patients. DESIGN AND SETTING: This was a cross-sectional study investigating the relationship between RV dysfunction and genetic defects in COPD patients. METHODS: Forty-one consecutive patients diagnosed with COPD and hospitalized due to acute exacerbation were enrolled. Polymorphism was analyzed using the strip assay technique. RV parameters were evaluated, and RV dysfunction was identified via transthoracic echocardiography. Patients were categorized into three groups according to gene polymorphism: MDR-1 CC (wild type, n = 9), MDR-1 CT (heterozygote mutant, n = 21) or MDR-1 TT (homozygote mutant, n = 11). RESULTS: The study included 14 males and 27 females (mean age 65 ± 11 years). The mean systolic pulmonary artery pressure was 31.4 ± 8 mmHg in the wild-type group, 42.2 ± 12 mmHg in the heterozygote mutant group and 46.5±14 mmHg in the homozygote mutant group (P = 0.027). Presence of RV dilatation was significantly different among the three groups (33%, 71%, and 100%, respectively; P = 0.005). In multiple logistic regression analysis, MDR-1 C3435T gene polymorphism (OR = 9.000, P = 0.019) was an independent predictor of RV dysfunction after adjustment for potential confounders. CONCLUSION: MDR-1 C3435T gene polymorphism was associated with RV dysfunction in patients with COPD.

RESUMEN

OBJECTIVE: Soluble suppression of tumorigenicity-2 (sST2), a member of the interleukin 1 receptor family, is increased in mechanical stress conditions and is produced by cardiomyocytes and cardiac fibroblasts. Elevated sST2 level is associated with the prognosis of acute coronary syndrome, pulmonary arterial hypertension, and acute and chronic heart failure (HF). In this study, we aimed to investigate the relationship between sST2 levels and cardiovascular mortality in outpatients with HF. METHODS: This study used a prospective observational cohort design. A total of 130 consecutive outpatients with HF were prospectively evaluated. Clinical characteristics, laboratory results, cardiovascular risk factors, comorbidities, and medication use were recorded. The patients were followed up for a mean period of 12±4 months for the development of cardiovascular death. They were classified into two groups: those who survived and those who died. RESULTS: Mean age of patients was 67±11 years (69% males). After follow-up, 23 of 130 patients (18%) experienced cardiovascular death. sST2 levels were higher among those who died compared with among those who survived [51 (21-162) vs. 27 (9-198) ng/mL, p<0.001]. Optimal cut-off sST2 level to predict cardiovascular mortality was found to be >30 ng/mL with a sensitivity of 87% and a specificity of 67% (AUC =0.808, 95% CI=0.730 to 0.872). sST2 levels were negatively correlated with left ventricular ejection fraction and triglyceride, total cholesterol, LDL cholesterol, and hemoglobin levels and were positively correlated with left atrium size and the presence of right ventricular dilatation. In multiple Cox regression analysis, sST2 level of >30 ng/mL (HR=6.756, p=0.002, 95% CI=1.983-23.018), hemoglobin level (HR=0.705, p<0.001, 95% CI=0.587-0.847), age (HR=1.050, p=0.013, 95% CI=1.010-1.091), and HDL cholesterol level (HR=0.936, p=0.010, 95% CI=0.889-0.984) remained to be associated with an increased risk of mortality. CONCLUSION: sST2 measurement could help risk stratification in outpatients with HF. Moreover, this is the first study describing the impact of sST2 protein in Turkish patients with HF.

RESUMEN

Length of stay is the primary driver of heart-failure hospitalization costs. Because cancer antigen 125 has been associated with poor morbidity and mortality rates in heart failure, we investigated the relationship between admission cancer antigen 125 levels and lengths of stay in heart-failure patients. A total of 267 consecutive patients (184 men, 83 women) with acute decompensated heart failure were evaluated prospectively. The median length of stay was 4 days, and the patients were classified into 2 groups: those with lengths of stay ≤4 days and those with lengths of stay >4 days. Patients with longer lengths of stay had a significantly higher cancer antigen 125 level of 114 U/mL (range, 9-298 U/mL) than did those with a shorter length of stay (19 U/mL; range; 3-68) (P <0.001). The optimal cutoff level of cancer antigen 125 in the prediction of length of stay was >48 U/mL, with a specificity of 95.8% and a sensitivity of 96% (area under the curve, 0.979; 95% confidence interval [CI], 0.953-0.992). In the multivariate logistic regression model, cancer antigen 125 >48 U/mL on admission (odds ratio=4.562; 95% CI, 1.826-11.398; P=0.001), sodium level (P<0.001), creatinine level (P=0.009), and atrial fibrillation (P=0.015) were also associated with a longer length of stay after adjustment for variables found to be statistically significant in univariate analysis and correlated with cancer antigen 125 level. In addition, it appears that in a cohort of patients with acute decompensated heart failure, cancer antigen 125 is independently associated with prolonged length of stay.

RESUMEN

BACKGROUND: Heart failure (HF) is a fatal disease. Plasma osmolality with individual impacts of sodium, blood urea nitrogen (BUN), and glucose has not been studied prognostically in patients with HF. AIM: This study aims to investigate the impact of serum osmolality on clinical endpoints in HF patients. METHODS: A total of 509 patients (383 males, 126 females) with HF with reduced ejection fraction in three HF centres were retrospectively analysed between January 2007 and December 2013. Follow-up data were completed for 496 patients. Plasma osmolality was calculated as (2 × Na) + (BUN/2.8) + (Glucose/18). Quartiles of plasma osmolality were produced, and the possible relationship between plasma osmolality and cardiovascular mortality was investigated. RESULTS: The mean follow-up was 25 ± 22 months. The mean age was 56.5 ± 17.3 years with a mean EF of 26 ± 8%. The mean levels of plasma osmolality were as follows in the quartiles: 1st % = 280 ± 6, 2nd % = 288 ± 1, 3rd % = 293 ± 2 (95% confidence interval [CI] 292.72-293.3), and 4th % = 301 ± 5 mOsm/kg. The EF and B-type natriuretic peptide levels were similar in the four quartiles. Univariate and multivariate analyses in the Cox proportional hazard model revealed a significantly higher rate of mortality in the patients with hypo-osmolality. The Kaplan-Meier plot showed graded mortality curves with the 1st quartile having the worst prognosis, followed by the 4th quartile and the 2nd quartile, while the 3rd quartile was shown to have the best prognosis. CONCLUSIONS: Our study results suggest that normal plasma osmolality is between 275 and 295 mOsm/kg. However, being close to the upper limit of normal range (292-293 mOsm/kg) seems to be the optimal plasma osmolality level in terms of cardiovascular prognosis in patients with HF.

RESUMEN

OBJECTIVE: New York Heart Association (NYHA) classification predicts prognosis for heart failure (HF) patients. Socioeconomic status (SES) has the potential to affect treatment strategy and disease course. The present objective was to investigate whether SES of Turkish HF patients affected NYHA classification. METHODS: Turkish research team-HF (TREAT-HF) is a questionnaire study with 52 questions, the purpose of which is to aid in the assessment of various qualities of HF patients. The 2013 TREAT-HF cohort included 503 patients from 11 centers in Turkey. Patients were divided into 2 groups according to NYHA functional classification: I-II, a better functional classification, or III-IV, a poorer functional classification. In addition, patients were analyzed according to gender. RESULTS: Evaluated were NYHA functional classifications of 459 (326 males and 133 females) patients with a mean age of 59.7±14.07 years and a mean ejection fraction (EF) of 31.7±9.22%. Total monthly family income level of ≥1000 TL, younger age, higher EF, and male gender were independently associated with better NYHA functional classification. In addition to EF, regular weight control was found to be independently associated with better NYHA classification for females, while younger age and income of ≥1000 TL were independently associated with better NYHA classification for males. CONCLUSION: The present results demonstrated that SES was associated with NYHA functional classification in a cohort of Turkish HF patients.

RESUMEN

OBJECTIVE: To evaluate the factors that affects the postperfusion syndrome in cadaveric liver transplantations and the effect of the postperfusion syndrome on discharge from the hospital. METHODS: Patients who underwent cadaveric liver transplantations between 2007 and 2013 were scanned retrospectively. Intraoperative anaesthesia records, intensive care unit follow-up forms and discharge reports were examined from patient files. Overall, 43 patients having complete data were included in the study. The postperfusion syndrome is defined as asystoli or a decrease in mean arterial pressure of more than 30%, which occurred in the first 5 min of reperfusion and continued for 1 min. Patients were divided into two groups: those who had the postperfusion syndrome and those who did not. RESULTS: The number of patients who had the postperfusion syndrome was 25 of 43 (58.1%). The MELD score of patients without the postperfusion syndrome was calculated as 16.9±3.2 and that of patients with the postperfusion syndrome was 19.7±3.6. A statistically significant relationship was detected between the postperfusion syndrome occurrence and a high MELD score (p=0.013). The diastolic blood pressure just before reperfusion was statistically lower in the group with the postperfusion syndrome than in the other group (p=0.023, 50±8 vs. 58±11). According to the logistic regression analysis, the MELD score and the decrease in diastolic blood pressure before reperfusion were defined as independent predictive factors. CONCLUSION: According to the study, the ratio for having the postperfusion syndrome was found to be 58.1%. The independent predictor factors affecting the postperfusion syndrome were detected as the MELD score and the decrease in diastolic blood pressure before reperfusion. The postperfusion syndrome during orthotropic liver transplantation is an important issue for anaesthesiologists. The awareness of the related factors with the postperfusion syndrome may help in the development of various preventive strategies.

RESUMEN

OBJECTIVE: Coronary artery bypass graft surgery in one of the most effective and widely used methods employed in the treatment of ischemic heart disease, but many factors to various degrees are directly associated with perioperative and postoperative problems. In this study, we evaluated the relationship between preoperative eosinophil count and postoperative mortality in patients who underwent coronary artery bypass graft operation. METHODS: A total of 241 patients (157 males, 84 females) who underwent isolated on-pump coronary artery bypass graft operation between 2011 and 2013 in two centers were evaluated retrospectively. The mean age of patients was 64 ± 11 years. After the mean 6.2 ± 0.8 month follow-up period, 36 (15%) of the 241 patients experienced cardiovascular death. Patients were classified into two groups as those who survived versus those who died. RESULTS: Eosinophil levels were lower among the patients who died compared to the patients who survived (0.8 [0-3.8] versus 1.7 [0-9.4] ×1000 cells/mm3; P < .001). Optimal cut-off level of eosinophils for predicting mortality was determined as ≤1.6 ×1000 cells/mm3, with a sensitivity of 85.7% and specificity of 51.0% (area under curve, 0.703; 95% CI, 0.641-0.760). CONCLUSION: Eosinopenia was used as the predictor of mortality in pediatric and adult patients in the intensive care units. Eosinopenia after coronary artery bypass graft can be related to the endogenous stress hormones, and insufficiency of the existing cardiac status. Eosinophil levels can assist and facilitate risk stratification for patients with coronary artery bypass graft.

RESUMEN

BACKGROUND: There are several studies evaluating the cardiac effects of carbon monoxide (CO) poisoning during the acute period; however, the number of studies evaluating the long-term cardiac effects is limited. OBJECTIVE: The present study aimed to evaluate the effects of blood carboxyhemoglobin (COHb) levels, elevated due to CO poisoning on the long-term development of acute myocardial infarction (AMI). METHODS: This cross-sectional cohort study included a total of 1013 consecutive patients who presented to the emergency department (ED) due to CO poisoning, between January 2005 and December 2007. The diagnosis of CO poisoning was made according to the medical history and a COHb level of greater than 5%. In terms of AMI development, the patients were followed up for an average of 56 months. RESULTS: At the end of follow-up, 100 (10%) of 1013 patients experienced AMI. Carboxyhemoglobin levels at the time of poisoning were higher among those who were diagnosed with AMI compared to those who were not (55%±6% vs 30%±7%; P<.001). Using a multivariate Cox proportional hazards model with forward stepwise method, age, COHb level, CO exposure time, and smoking remained associated with an increased risk of AMI after adjustment for the variables found to be statistically significant in a univariate analysis. According to a receiver operating characteristic curve analysis, the optimal cutoff value of COHb used to predict the development of AMI was found to be greater than 45%, with 98% sensitivity and 94.1% specificity. CONCLUSION: In patients presenting to the ED with CO poisoning, COHb levels can be helpful for risk stratification in the long-term development of AMI.

RESUMEN

INTRODUCTION: Atrial fibrillation (AF) is a common arrhythmia in heart failure (HF). Recent studies have shown that serum cancer antigen-125 (CA-125) levels are elevated in HF, and high levels of CA-125 in HF patients with sinus rhythm have been shown to be associated with the development of new onset AF. However, the relation between CA-125 levels and the presence of AF in HF is unknown. In this study we investigated whether plasma CA-125 levels in patients with systolic HF could predict the presence of AF. METHODS: The study was a retrospective cohort design including 205 stable systolic HF patients who were selected during outpatient clinic visits and who had CA-125 measurement and an electrocardiogram within the last one month before admittance to cardiology clinic. Patients were classified into two groups based on the presence of AF (n = 67) or sinus rhythm (n = 138). RESULTS: The mean age of the patients was 68 ± 11 years. CA-125 levels were significantly higher in patients with AF than patients with SR [33 (3-273) vs 102 (7-296) U/ml, P < 0.001]. CA-125 level, presence of right ventricular dilatation, pericardial effusion, moderate to severe TR and MR, and left atrial diameter were found to be associated with the presence of AF in univariate analysis. In a multivariate logistic regression model, only the CA-125 level remained associated. Also, according to the ROC curve analysis, the optimal cut-off level of CA-125 for predicting AF was ≥ 91 U/mL with a specificity of 84% and a sensitivity of 54%. CONCLUSION: We have shown that the CA-125 levels can be used to predict AF in patients with systolic HF.

RESUMEN

OBJECTIVE: Endothelial dysfunction, secondary to systemic inflammation and oxidative stress, is known to play a major role in the development and progression of atherosclerosis. It is hypothesized that the lower incidence of coronary artery disease in the premenopausal period in females when compared with males is associated with regular menstrual blood loss. We investigated whether regular blood donation (BD) is associated with improved endothelial function in healthy adult males. METHODS: Fifty young healthy male volunteers volunteers with a mean age of 30 ± 6 years without overt cardiovascular disease were enrolled to participate in serial consecutive BDs. Serum iron levels as oxidative stress parameters, flow-mediated dilatation (FMD) for endothelial function, 24-h mean diastolic blood pressure for peripheral vascular resistance identification, and high-sensitivity C-reactive protein (hs-CRP) levels as systemic inflammatory markers were evaluated before and after BD. This study used a prospective observational cohort design. Patients with cardiovascular and inflammatory diseases were excluded. RESULTS: BD was found to improve FMD steadily and significantly when compared with the baseline (mean ± SD: 9.9% ± 3.8%, 10.44% ± 3.9%, 10.65% ± 3.9%, and 10.75 ± 3.9%, respectively, p=0.15, p=0.02, p=0.006 as compared with the baseline). A steady decrease was identified in hs-CRP levels after serial BDs, although this decrease was not statistically significant in the all phases (2.96 ± 3.3 mg/L, 2.26 ± 1.5 mg/L, and 2.12 ± 1.5 mg/L, respectively, p=0.829, p=0.558). The 24-h mean diastolic blood pressures were significantly lower in the chronic phase (77 ± 9 mm Hg, 75 ± 7 mm Hg, and 72 ± 8 mm Hg, respectively, p=0.50, p=0.003), whereas there was no significant change in iron levels in the acute and chronic phases (66 ± 32 mg/dL, 72 ± 43 mg/dL, and 68 ± 33 mg/dL, respectively, p=1.000, p=1.000). CONCLUSION: The results of the study indicate that regular BD improves endothelial function.

RESUMEN

CONTEXT AND OBJECTIVE: The location of embolism is associated with clinical findings and disease severity in cases of acute pulmonary embolism. The level of gamma-glutamyl transferase increases under oxidative stress-related conditions. In this study, we investigated whether gamma-glutamyl transferase levels could predict the location of pulmonary embolism. DESIGN AND SETTING: Hospital-based cross-sectional study at Cumhuriyet University, Sivas, Turkey. METHODS: 120 patients who were diagnosed with acute pulmonary embolism through computed tomography-assisted pulmonary angiography were evaluated. They were divided into two main groups (proximally and distally located), and subsequently into subgroups according to thrombus localization as follows: first group (thrombus in main pulmonary artery; n = 9); second group (thrombus in main pulmonary artery branches; n = 71); third group (thrombus in pulmonary artery segmental branches; n = 34); and fourth group (thrombus in pulmonary artery subsegmental branches; n = 8). RESULTS: Gamma-glutamyl transferase levels on admission, heart rate, oxygen saturation, right ventricular dilatation/hypokinesia, pulmonary artery systolic pressure and cardiopulmonary resuscitation requirement showed prognostic significance in univariate analysis. The multivariate logistic regression model showed that gamma-glutamyl transferase level on admission (odds ratio, OR = 1.044; 95% confidence interval, CI: 1.011-1.079; P = 0.009) and pulmonary artery systolic pressure (OR = 1.063; 95% CI: 1.005-1.124; P = 0.033) remained independently associated with proximally localized thrombus in pulmonary artery. CONCLUSIONS: The findings revealed a significant association between increased existing embolism load in the pulmonary artery and increased serum gamma-glutamyl transferase levels.

Eles foram divididos em dois grupos principais (localização proximal e distal) e depois em subgrupos de acordo com a localização do trombo da seguinte forma: primeiro grupo (trombo na artéria pulmonar [AP] principal, n = 9); segundo (trombo no ramo da AP principal; n = 71); terceiro grupo (trombo na segmentar da AP; n = 34); quarto grupo (trombo na subsegmentar da AP; n = 8). RESULTADOS : Na análise univariada, os níveis de GGT tiveram significado prognóstico em relação à admissão, pulsação arterial, saturação de oxigênio, dilatação do ventrículo direito/hipocinesia, pressão sistólica da artéria pulmonar (PSAP) e necessidade de ressuscitação cardiopulmonar. O modelo de regressão logística multivariada demonstrou que o nível de GGT na admissão (razão de possibilidades, OR: 1,044; 95% intervalo de confiança, CI: 1,011-1,079; P = 0,009) e PSAP (OR: 1,063, 95% CI: 1,005-1,124; P = 0,033) permaneceram independentemente associados com trombo localizado proximalmente na AP. CONCLUSÕES : Os resultados demonstraram associação significativa entre aumento da carga existente de embolia da AP e aumento dos níveis séricos da GGT.

RESUMEN

OBJECTIVE: In heart failure (HF) patients, functional capacity has been demonstrated to be a marker of poor prognosis, independent of left ventricular ejection fraction (EF). Lymphocyte count is currently recognized in certain risk stratification scores for chronic HF, and severe HF is associated with lymphocytopenia. However, no data exists on the association between lymphocyte count and functional capacity in patients with stable HF. This study aimed to assess the relationship between lymphocyte count and New York Heart Association (NYHA) functional capacity in systolic HF outpatients. METHODS: The Turkish Research Team-HF (TREAT-HF) is a network which undertakes multi-center observational studies in HF. Data on 392 HF reduced ejection fraction (HFREF) patients from 8 HF centers are presented here. The patients were divided into two groups and compared: Group 1 comprised stable HFREF patients with mild symptoms (NYHA Class I-II), while Group 2 consisted of patients with NYHA Class III-IV symptoms. RESULTS: Patient mean age was 60±14 years. Lymphocyte count was lower in patients with NYHA functional classes III and IV than in patients with NYHA functional classes I and II, (0.9 [0.6-1.5]x1000 versus 1.5 [0.7-2.2]x1000, p<0.001). In multivariate logistic regression analysis, lymphocyte count (OR: 0.602, 95% CI: 0.375-0.967, p=0.036), advanced age, male gender, presence of hypertension, EF, left atrium size, systolic pulmonary artery pressure, neutrophil and basophil counts, creatinine level, and diuretic usage were associated with poor NYHA functional class in systolic HF outpatients. CONCLUSION: The present study demonstrated that in stable HFREF outpatients, lymphocytopenia was strongly associated with poor NYHA function, independent of coronary heart disease risk factors.

RESUMEN

BACKGROUND: Cancer antigen-125 (CA-125) might be a useful biomarker to predict long-term mortality in patients with recent exacerbation of chronic obstructive pulmonary disease (COPD). METHODS: A total of 87 consecutive patients with COPD were evaluated prospectively. Mean age of patients was 68 ± 10 years (55% males, 45% females) with a median follow-up period of 49 months. Optimal cut-off value of CA-125 to predict mortality was found as >93.34 U/ml, with 91% specificity and 40% sensitivity. RESULTS: After follow-up, 20 out of 87 (23%) experienced cardiovascular death. CA-125 levels were higher among those who died compared to those who survived [55 (12-264) versus 28 (5-245) U/ml, p = 0.013]. In multivariate Cox proportional-hazards model with forward stepwise method, only CA-125 > 93.34 U/ml on admission (HR = 3.713, 95% CI: 1.035-13.323, p = 0.044) remained associated with an increased risk of death. CONCLUSIONS: For the first time, we demonstrated that CA-125 helps the risk stratification of patients with COPD.

RESUMEN

OBJECTIVE: Cardiopulmonary resuscitation (CPR) is a series of lifesaving actions that improve the chance of survival following cardiac arrest (CA). Many clinical and laboratory parameters, such as the presence of asystole, out-of-hospital CPR, and duration of cardiac arrest, are associated with failed CPR in patients with CA. Asystole is a state of no cardiac electrical activity, along with the absence of contractions of the myocardium and absence of cardiac output. Oxidative stress index (OSI), which is the ratio of total oxidative status to total antioxidant status, increases by ischemia-reperfusion injury. We investigated whether OSI levels in patients with CA could predict early mortality after CPR. METHODS: This study has a prospective observational cohort design. Five patients with a history of cancer, four patients who developed hemolysis in their blood, six patients who were transferred to our hospital from other hospitals, and six patients in whom blood samples for OSI could not be stored properly were excluded. Finally, a total of 90 in-hospital or out-of-hospital CA patients and 40 age- and sex-matched healthy volunteers as the control group were evaluated prospectively. The patients were classified according to the CPR response into a successful group (n=46) and a failed group (n=44). Comparisons between groups were performed using one-way ANOVA with post hoc analysis by Tukey's HSD or independent samples t-test and the Kruskal-Wallis tests or Mann- Whitney U test for normally and abnormally distributed data, respectively. Also, we used chi-square test, Spearman's correlation test, univariate and multible logistic regression analyses, and receiver operator characteristic curve analysis. RESULTS: OSI was 3.0±4.0, 5.6±4.3, and 8.7±3.8 in the control group, the successful CPR group, and the failed CPR group, respectively (p<0.001 for the 2 comparisons). OSI on admission, ischemia-modified albumin, presence of asystole, mean duration of cardiac arrest, out-of-hospital CPR, pH, and potassium and sodium levels were found to have prognostic significance in the univariate analysis. In the multivariate logistic regression model, OSI on admission (OR=1.325, p=0.003), ischemia-modified albumin (OR=1.008, p=0.005), presence of asystole (OR=13.576, p<0.001), and sodium level (OR=1.132, p=0.029) remained associated with an increased risk of early mortality. In addition, the optimal cut-off value of OSI to predict post-CPR mortality was measured as >6.02, with 84.1% sensitivity and 76.1% specificity. CONCLUSION: Elevated OSI levels can predict failed CPR in CA patients.

RESUMEN

BACKGROUND: Outcomes in patients requiring coronary artery bypass graft (CABG) surgery have been improved with devices such as the intra-aortic balloon pump (IABP). Good coronary collateral circulation (CCC) has been shown to reduce mortality in patients with coronary artery disease (CAD). We aimed to investigate whether poor preoperative CCC grade is a predictor of in-hospital mortality in CABG surgery requiring IABP support. METHODS: Fifty-five consecutive patients who were undergoing isolated first time on-pump CABG surgery with IABP support were enrolled into this study and CCC of those patients was evaluated. RESULTS: Twenty-seven patients had poor CCC and 28 patients had good CCC. In-hospital mortality rate in poor CCC group was significantly higher than good CCC group (14 (50%) vs. 4 (13%), P = 0.013). Preoperative hemoglobin level (OR: 0.752; 95% CI, 0.571-0.991, P = 0.043), chronic obstructive pulmonary disease (OR: 6.731; 95% CI, 1.159-39.085, P = 0.034) and poor CCC grade (OR: 5.750; 95% CI, 1.575±20.986, P = 0.008) were associated with post-CABG in-hospital mortality. Poor CCC grade (OR: 4.853; 95% CI, 1.124-20.952, P = 0.034) and preoperative hemoglobin level (OR: 0.624; 95% CI, 0.476-0.954, P = 0.026) were independent predictors of in-hospital mortality after CABG. CONCLUSION: Preoperative poor CCC and hemoglobin are predictors of in-hospital mortality after CABG with IABP support.
