The coronavirus disease 2019 (COVID-19) outbreak remains a major public health challenge worldwide. The present study investigated the effect of COVID-19 on blood pressure (BP) during short term follow-up. A total of 211 consecutive COVID-19 patients who were admitted to Parkhayat Kutahya hospital were retrospectively screened. Information was obtained from the electronic medical records and National health data registry. The study outcome was new onset of hypertension according to the Eight Joint National Committee and European Society of Cardiology Guidelines. Finally, 153 confirmed COVID-19 patients (mean age 46.5 ± 12.7 years) were enrolled. Both systolic (120.9 ± 7.2 vs 126.5 ± 15.0 mmHg, P <.001) and diastolic BP (78.5 ± 4.4 vs 81.8 ± 7.4 mmHg, P <.001) were significantly higher in the post COVID-19 period than on admission. New onset hypertension was observed in 18 patients at the end of 31.6 ± 5.0 days on average ( P <.001). These findings suggest that COVID-19 increases systolic and diastolic BP and may cause new onset hypertension.

Objective: The extent of severity and complexity of coronary artery disease (CAD) in patients presenting with ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) and possible correlations between serum 25-hydroxyvitamin D (25(OH)D) have not yet been adequately studied. We evaluated the relationship between 25(OH)D levels and the burden of CAD as assessed by the SYNTAX score (SXscore) in patients with acute coronary syndrome (ACS) including STEMI and NSTEMI., Methods: After exclusion, a total of 113 patients who were admitted to our hospital due to ACS and who were referred for undergoing coronary angiography were prospectively included. Their mean age was 63.3±18.5 years, and 80.5% of them were men. In total, 44.2% of the patients had NSTEMI and the remaining had STEMI. Blood samples were drawn at admission to evaluate serum 25(OH)D levels. CAD severity was assessed using the SXscore. Patients were classified as having low (SXscore ≤22) or high (SXscore >22) SXscores. Pearson's and Spearman's correlation coefficients were used to examine the relationship between serum 25(OH)D levels and the SXscore., Results: 25(OH)D levels were significantly lower in the group with a high SXscore than in the group with a low SXscore (21.0±8.0 vs. 16.7±6.8, p=0.005). Correlation analysis showed a significant correlation between 25(OH)D levels and the SXscore. Multiple linear regression (MLR) analysis was used to determine the significance of the relationship between the SXscore and 25(OH)D, parathyroid hormone, and C-reactive protein levels and eGFR. MLR analysis revealed that only 25(OH)D levels (coefficient beta, -0.217, p=0.029) was significantly associated with the severity of CAD., Conclusion: The present study showed that serum 25(OH)D levels were significantly lower in patients with STEMI/NSTEMI and that low serum 25(OH)D levels were significantly correlated with CAD severity and extent.

Objective: The aim of this study was to investigate the association between platelet-to-lymphocyte ratio (PLR) and atrial fibrillation (AF) after coronary artery bypass graft (CABG) surgery., Subjects and Methods: A total of 125 patients were retrospectively analyzed. AF was diagnosed using standard clinical criteria, and PLR was calculated as the ratio of the platelets to lymphocytes, obtained from the blood samples that were taken in the fasting state before CABG surgery. The association of different variables with postoperative AF and PLR was calculated using univariate and multivariate analysis. The receiver operating characteristics curve was used to determine the sensitivity and specificity of PLR and the optimal cutoff value for predicting post-CABG AF., Results: Of the 125 patients, 50 with AF (mean age: 67.0 ± 9.5 years, 38 males and 12 females) and 75 patients without AF (mean age: 61.1 ± 9.1 years, 58 males and 17 females) were identified, and the difference in the mean age was statistically significant (p = 0.01). PLR was also significantly higher in those with AF (152.8 ± 82.2) than those without AF (118.2 ± 32.9) (p = 0.012). Univariate analysis showed that age and PLR were associated with AF after CABG surgery (p < 0.001 and p = 0.005, respectively). Using a multivariate logistic regression model with the backward elimination method, age and PLR remained as independent predictors of AF after CABG surgery (p < 0.001 and p = 0.005, respectively). PLR levels >119.3 predicted postoperative AF with 64% sensitivity and 56% specificity (AUC: 0.634, p = 0.012)., Conclusion: In this study, age and PLR level were independent predictors of AF after CABG surgery. Patients with an elevated preoperative PLR were at higher risk of AF after CABG surgery., (© 2016 S. Karger AG, Basel.)

Aim: Anthracycline-derived antineoplastic agents are used as the main form of treatment in many malignant diseases, including breast cancer and childhood cancers. Cardiotoxicity is one of the most feared life-threatening complications of cancer therapy. In the present study, we aimed to investigate the relationship between plasma hyaluronan (HA) levels and anthracycline-induced cardiotoxicity., Materials and Methods: Fifty eight of 73 female patients who were diagnosed with breast cancer and treated with a chemotherapy regimen including anthracycline were enrolled in this study. Anamneses were taken from each patient before and after chemotherapy. Further, physical examinations, electrocardiography, and transthoracic echocardiography were performed, and plasma hyaluronan levels were determined by using ELISA assay for each patient before and after treatment., Results: Following anthracycline-based chemotherapy, the average left ventricular ejection fraction decreased (62.6±3.7% vs. 58.6±4.4%, p<0.001), and diastolic functions significantly deteriorated (p<0.001). However, troponin and hyaluronan levels significantly increased following chemotherapy [Troponin (ng/ml, mean±SD): before 0.01±0.002, after 0.037±0.02, p<0.001], [Plasma HA (ng/ml, mean±SD): before 41.3±5.4, after 70±8.5, p<0.001]. The increase in troponin values correlated with systolic dysfunction (p=0.002), but did not correlate with diastolic dysfunction (p=0.661). Significant correlations were found between systolic/diastolic dysfunction and plasma HA levels (r=0.417, p=0.001; r=0.339, p=0.009, respectively)., Conclusions: Both systolic and diastolic functions were significantly deteriorated after chemotherapy. In addition, plasma levels of HA and troponin increased after treatment. Further, both systolic and diastolic dysfunctions were found to correlate with serum HA levels. All these data suggest that HA might have a function on anthracycline-induced cardiotoxicity., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Coronary artery bypass grafting (CABG) surgery maintains an important role in the treatment of coronary artery disease. The huge saphenous vein graft aneurysm (HSVGA) is rare and occurs as a late complication after CABG. Here, we reported a case of HSVGA presenting as non-ST elevation myocardial infarction., (Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.)

Objective: The aim of this study was to highlight the use of combined intravenous lipid emulsion (ILE) and plasma exchange (PE) therapies in multidrug toxicity., Clinical Presentation and Intervention: A 45-year-old woman who attempted suicide by ingesting large quantities of amisulpride (28 g), diazepam (250 mg), valsartan (2,240 mg), aripiprazole (45 mg) and paliperidone (21 mg) was taken to the hospital of Adnan Menderes University School of Medicine. Upon arrival, she exhibited signs of cardiotoxicity and severe depression of the central nervous and respiratory systems. She was treated successfully with ILE for 4 h and PE therapy for 36 h, consecutively. She was discharged on the fourth day of hospitalization having fully recovered., Conclusion: The patient was successfully treated with the combination of ILE and PE., (© 2016 S. Karger AG, Basel.)

Early and accurate risk prediction is an important clinical demand in patients with infective endocarditis (IE). The platelet-to-lymphocyte ratio (PLR) is an independent predictor of worse prognosis in various cardiovascular diseases. The aim of this study was to determine the value of PLR in the prediction of in-hospital mortality among IE patients. We retrospectively analyzed the clinical, laboratory, and echocardiographic data of 59 adult patients with definite IE and in 40 adult controls. In-hospital mortality occurred in 16 (27%) patients. Vegetation size, levels of high-sensitive C-reactive protein and procalcitonin, neutrophil-to-lymphocyte ratio, and PLR were significantly higher in the in-hospital-mortality-positive group than in the in-hospital-mortality-negative group (p = 0.004, p = 0.009, p = 0.030, p = 0.001, and p = 0.008, respectively). Lymphocyte count was, however, significantly lower in the in-hospital-mortality-positive group (p = 0.004). In the receiver-operating characteristic analysis, PLRs over 191.01 predicted in-hospital mortality with 56.3% sensitivity and 81.4% specificity [area under the curve 0.725, 95% confidence interval (CI) 0.594-0.833; p = 0.0027]. In the multivariate analysis, PLR was found to be an independent predictor of in-hospital mortality in patients with IE (odds ratio 1.022, 95% CI 1.003-1.042; p = 0.021). In conclusion, higher PLR may predict in-hospital mortality in patients with IE., (Copyright © 2015. Published by Elsevier Taiwan.)

Objectives: Spontaneous echo contrast (SEC) is the presence of smoke-like echoes with a characteristic swirling motion of the blood in echocardiography. Previous clinical studies have shown that SEC is a risk factor for left atrial thrombus formation and a predictor of potential systemic embolism originating from the heart. There is an association between uric acid and prothrombotic state. Therefore, we aimed to investigate the role of uric acid in SEC in patients with mitral stenosis (MS)., Methods: A total of 85 consecutive patients with MS were enrolled in the study. Patients were divided into two groups according to whether SEC was present in the left atrium., Results: There were 41 patients (mean age 46.4 ± 11.4 and 68% female) in the SEC(-) group and 44 patients (mean age 45.7 ± 7.2 and 64% female) in the SEC(+) group. High sensitive C-reactive protein (hs-CRP) levels were significantly higher in the SEC(+) group than in the SEC(-) group (9.5 ± 4.2 vs. 4.7 ± 2.2 mg/L, P < 0.001). Uric acid was also significantly higher in the SEC (+) group (6.3 ± 1.4 vs. 4.5 ± 1.3 mg/dL, P < 0.001). In receiver operating characteristics curve analysis, uric acid >5.2 mg/dL had a 73% sensitivity and 76% specificity in predicting SEC in patients with MS. At multivariate analysis, uric acid (OR 3.919, 95% CI 1.911-8.035; P < 0.002) was an independent risk factor for SEC in patients with MS., Conclusion: Uric acid is independently associated with SEC in patients with MS. Our findings suggest that this inexpensive, universally available marker may be a useful biomarker for the stratification of risk in patients with MS., (© 2015, Wiley Periodicals, Inc.)

We evaluated the acute effect of intracoronary administration of tirofiban on no-reflow phenomenon in patients with ST-segment elevated myocardial infarction undergoing primary percutaneous coronary intervention. Consecutive patients (n = 162) were randomized into 2 groups based on whether intracoronary tirofiban was administered. After the administration of intracoronary tirofiban, thrombolysis in myocardial infarction (TIMI) flow grade significantly increased (P < .001) and successful reperfusion was achieved in 26 (32%) patients. In the placebo group, however, after the administration of intracoronary placebo the TIMI flow grade did not change (P = .070), and successful reperfusion was achieved only in 8 (10%) patients. In-hospital major adverse cardiac events (MACE) were significantly lower in the tirofiban group (36% vs 19%, P = .013). Intracoronary administration of tirofiban significantly improves TIMI flow grade and is associated with a lower in-hospital rate of MACE., (© The Author(s) 2014.)

Objective: Oral contraceptive pills (OCP) are widely used for treating women with polycystic ovary syndrome (PCOS). Metformin has beneficial effects on insulin resistance and endothelial functions. The aim of this study was to investigate the effects of treatment with drospirenone/ethinyl estradiol (EE) alone or in combination with metformin on the flow-mediated vasodilatation (FMD) and carotid intima media thickness (CIMT) in women with PCOS., Methods: Fifty women with PCOS (mean age 23 ± 5) were randomized to oral treatment of OCP alone (n = 25) or an OCP combination with metformin (n = 25) for 6 months. FMD from the brachial artery and CIMT were calculated. The hormonal profile, HOMA-IR score, basal insulin and glucose levels were studied in both groups. Before and after 6 months' treatment, echocardiographic measurements and laboratory tests were also obtained., Results: After 6 months' treatment we observed a small decrease in FMD in the OCP group (14.9 ± 9.4 versus 14.4 ± 9.9, p = 0.801) and a slight increase in the combination group (14.5 ± 9.1 versus 15.0 ± 8.0, p = 0.715) but neither of them reached significance. CIMT increased in the OCP group (0.048 ± 0.011 to 0.050 ± 0.010 cm, p = 0.433) and decreased slightly in the combination group (0.049 ± 0.012, 0.048 ± 0.011 cm, p = 0.833)., Conclusion: We demonstrated that adding metformin to OCP treatment may have beneficial effect on FMD and CIMT that represent vascular function in patients with PCOS. These results suggest that adding metformin to OCP treatment for PCOS could preserve the cardiovascular system and improve it.

Although mean platelet volume (MPV) is an independent correlate of impaired angiographic reperfusion and 6-month mortality in ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), there is less data regarding the association between platelet distribution width (PDW) and in-hospital major adverse cardiovascular events (MACEs). A total of 306 patients with STEMI pPCI were evaluated. No reflow was defined as a post-PCI thrombolysis in myocardial infarction (TIMI) flow grade of 0, 1, or 2 (group 1). Angiographic success was defined as TIMI flow grade 3 (group 2). The values of MPV and PDW were higher among patients with no reflow. In-stent thrombosis, nonfatal myocardial infarction, in-hospital mortality, and MACEs were significantly more frequent among patients with no reflow. In multivariate analysis, PDW, MPV, high-sensitivity C-reactive protein, and glucose on admission were independent correlates of in-hospital MACEs. Admission PDW and MPV are independent correlates of no reflow and in-hospital MACEs among patients with STEMI undergoing pPCI., (© The Author(s) 2013.)

Objectives: The aim of this study was to evaluate the association of the levels of red blood cell distribution width (RDW) with the severity of atherosclerosis and to determine whether or not the RDW level on admission is an independent predictor of all-cause mortality in patients with non-ST elevation myocardial infarction (NSTEMI)., Materials and Methods: A total of 335 consecutive patients with NSTEMI were enrolled in this study. The patients were divided into high (n = 105) and low (n = 230) SYNTAX groups. The high SYNTAX group was defined as patients with a value in the third tertile (SYNTAX score, SXscore ≥12), while the low SYNTAX group was defined as those with a value in the lower 2 tertiles (SXscore <12). The high RDW group (n = 152) was defined as patients with RDW >14.25% and the low RDW group (n = 183) as those with RDW ≤14.25%. All-cause mortality was followed up to 38 months., Results: The mean follow-up period was 18 ± 11 months. The RDW levels of patients were significantly higher in the high SYNTAX group than in the low SYNTAX group (15.2 ± 1.8 vs. 14.2 ± 1.2, p < 0.001). Pearson's coefficients were used to determine the degree of association between RDW levels and SXscore and also between RDW levels and high-sensitivity C-reactive protein. There was a significant correlation between RDW levels and SXscore (r = 0.460, p < 0.001). Also, there was a significant correlation between RDW levels and high-sensitivity C-reactive protein (r = 0.180, p = 0.001). All-cause mortality rate was not significantly different between the high and low RDW groups (log-rank, p = 0.621)., Conclusion: RDW levels were independently associated with high SXscore but were not associated with long-term mortality in NSTEMI patients., (© 2014 S. Karger AG, Basel.)

In this study we aimed to investigate whether there is an association between the neutrophil to lymphocyte ratio (NLR) and severity of coronary artery disease (CAD) in patients with non-ST segment elevation myocardial infarction (NSTEMI) using the SYNTAX score (SXscore). A total of 414 patients with NSTEMI who underwent coronary angiography were enrolled in the study. NLR was measured for all patients at presentation. The study population was then divided into 3 tertiles based on the SYNTAX trial results.(1)) The low syntax group (n = 329) was defined as those with an SXscore ≤ 22, the intermediate syntax group (n = 58) was defined as an SXscore ≥ 23 and < 33, and the high syntax group (n = 27) as those with an SXscore ≥ 33. NLR was significantly lower in patients with a low SXscore compared to patients with an intermediate SXscore or high SXscore (3.7 ± 4 to 4.6 ± 2 and 7.9 ± 4, P < 0.001). Linear regression analysis revealed that NLR (coefficientβ = 0.380, 95%CI: 1.165-1.917, P < 0.001) was significantly associated with the SXscore in patients with NSTEMI. Our results indicate that NLR is independently associated with the severity of CAD in patients with NSTEMI.

Aims: The protective effect of beta-blockers, ACE inhibitors, and ARBs on anthracycline cardiotoxicity has already been demonstrated, but the effect of aldosterone antagonism, which inhibits the last step of the renin-angiotensin-aldosterone system (RAAS), was questioned. This study sought to investigate whether spironolactone protects the heart against anthracycline-induced cardiotoxicity., Methods and Results: Eighty-three female patients who were diagnosed with breast cancer were included in the study. The study population was randomized into spironolactone and control groups. A dose of 25 mg/day spironolactone was administered to the patients in the spironolactone group. There were 43 patients (mean age 50 ± 11 years) in the spironolactone group and 40 patients (mean age 51 ± 10 years) in the control group. LVEF decreased from 67.0 ± 6.1 to 65.7 ± 7.4 (P = 0.094) in the spironolactone group, and from 67.7 ± 6.3 to 53.6 ± 6.8 in the control group (P < 0.001). When the general linear model was applied, the interaction of LVEF decrease between groups was significantly lower in the spironolactone group than in the control group (P < 0.001). The diastolic functional grade of subjects in the spironolactone group was protected (P = 0.096), whereas it deteriorated in the control group (P < 0.001)., Conclusion: We showed that spironolactone administration used simultaneously with anthracycline group chemotherapeutics protects both myocardial systolic and diastolic functions. Spironolactone can be used to protect against anthracycline-induced cardiotoxicity., Trial Registration: NCT02053974., (© 2014 The Authors.

Introduction: Sufficient coronary collateral circulation (CCC) protects myocardial tissue against ischemia in patients with coronary chronic total occlusion (CTO). Vitamin D is a steroid hormone which has been related to increased prevalence of hypertension, left ventricular hypertrophy, heart failure, peripheral artery disease, coronary artery disease, myocardial infarction and cardiovascular mortality., Aim: To investigate whether there is an association between serum 25-hydroxy-vitamin D levels and development of CCC in patients with coronary CTO., Material and Methods: A total of 188 patients with CTO at coronary angiography were included in this study. Vitamin D and parathyroid hormone (PTH) levels were measured on the day of coronary angiography. Development of collateral circulation was graded according to the Rentrop classification after coronary angiography. Then, patients were divided into two groups on the basis of CCC grades: group 1 included 68 (36%) patients with poorly developed CCC, and group 2 included 120 (64%) patients with well-developed CCC., Results: Patients with poorly developed CCC had significantly lower serum 25-hydroxy-vitamin D levels compared to those with well-developed CCC (20 ±3 vs. 30 ±6 ng/ml, p<0.0001). Multivariate logistic regression analysis indicated serum 25-hydroxyvitamin D (25(OH)D) (OR = 1.794, 95% confidence interval (CI): 1.453-2.216; p<0.001) as an independent predictor of poor collateral flow in patients with CTO., Conclusions: Low vitamin D level is an independent predictor of poor CCC in patients with CTO.

We investigated the predictors of endothelial dysfunction in patients with rheumatoid arthritis (RA) by brachial artery flow-mediated vasodilatation (FMD). The study population included 50 patients with RA and 30 controls. Disease activity score (DAS28) was calculated for patients with RA. An FMD response <7% was accepted as impaired FMD. Brachial artery Doppler study revealed that in patients with RA, FMD% was significantly lower as compared with controls (6.6% ± 3.5% vs 9.7% ± 41%, P = .002). After multivariate logistic regression analysis, erythrocyte sedimentation rate (ESR; OR: 1.086, 95% confidence interval [CI]: 1.012-1.167, P = .023), duration of RA (OR: 1.392, 95% CI: 1.044-1.856, P = .024), and DAS28 (OR: 3.335, 95% CI: 1.067-10.42, P = .038) were independent predictors of impaired FMD in patients with RA. Endothelial function is impaired in patients with RA. Disease duration, DAS28, and ESR indicating active inflammation are independent predictors of impaired FMD in patients with RA., (© The Author(s) 2013.)

Aims: To evaluate the safety and efficacy of the new Cera septal occluder (CSO) for atrial septal defect (ASD) closure as compared to the AMPLATZER Septal Occluder (ASO)., Methods and Results: A total of 405 ASD patients receiving CSO or ASO were studied. The ASDs were classified into simple defects (isolated defects <26 mm) or complex defects (isolated defects ≥26 mm, large defects with a deficient rim, double or multi-fenestrated defects). Clinical and echocardiographic findings were collected before discharge, at one month, and every six months after implantation. Two hundred and five (133 females, aged 30±13 years) and 200 (135 females, aged 28±14 years) patients received CSO and ASO implants, respectively. The CSO group had similar ASD and device sizes, prevalence of complex lesions, procedural times and success rates as compared to the ASO group. Echocardiographic follow-up at one and six months showed similar residual shunts between devices. Both groups had similar rates for device embolisation and atrial arrhythmia. The average equipment cost per patient was lower in the CSO group than in the ASO group (US $3,500 vs. US$5,600, p<0.001)., Conclusions: Transcatheter ASD closure with CSO is safe and effective. It appears to be an attractive alternative to ASO because of its relatively low cost.

Objectives: The aim of this study was to investigate the protective effect of topical rifamycin SV treatment against sternal wound infection (SWI) in diabetic patients undergoing on-pump coronary artery bypass graft (CABG) surgery., Methods: One hundred and fifty-nine diabetic patients who were scheduled to undergo isolated on-pump CABG surgery were included. Eight were excluded for various reasons. Of the 151 patients, 51 were on insulin therapy and 100 were on oral anti-diabetics. The risk of mediastinitis was assessed using the American College of Cardiology/American Heart Association 2004 guideline update for CABG surgery. According to the risk scores, patients were divided into two comparable groups: the rifamycin group (n = 78) received topical rifamycin treatment after on-pump CABG surgery, and the control group (n = 73) received no topical treatment., Results: Deep sternal wound infection (mediastinitis) was not observed in either group (0/78 vs 0/73, p = 1.0). No superficial sternal wound infection was observed in the rifamycin group, however, it did occur in one patient in the control group (0/78 vs 1/73, p = 0.303). Wound culture was performed and coagulase-negative staphylococci were observed. The infection regressed on initiation of antibiotic therapy against isolated bacteria and the patient was discharged after a full recovery., Conclusions: Although the difference in rate of superficial sternal wound infection (SSWI) in the rifamycin and control groups was not statistically significant, locally applied rifamycin SV during closure of the sternum in the CABG operation may have had a protective affect against SWI.

Introduction: Some reports have shown increased platelet aggregation and activation in patients with pulmonary artery hypertension (PAH). Mean platelet volume (MPV) is a simple and easy method of assessing platelet function. We aimed to investigate the mean platelet volume levels in patients with atrial septal defect (ASD) and the association between MPV levels and pulmonary artery hypertension., Method: One hundred and forty consecutive patients (42 males and mean age 35 +/- 9 y) and forty healthy controls (15 males and mean age 35 +/- 4 y) were enrolled in the study between December 2008 and February 2011., Results: The ASD group demonstrated a significantly higher right ventricular size and pulmonary artery pressure than the control group (42 +/- 4 mm vs. 36 +/- 3 mm and 43 +/- 12 mmHg vs. 32 +/- 11 mmHg; P < 0.001 and P < 0.001, respectively). MPV levels were higher in the ASD group than the control group (9.3 +/- 1.2 fl vs. 8.6 +/- 0.8 fl, P < 0.001). There was a significant, positive correlation between MPV and systolic pulmonary artery pressure (PAP) (r = 0.542 and P < 0.001) in the ASD group. MPV was also significantly correlated with right ventricular size but not ASD diameter in the ASD group (r = 0.441, P < 0.001 and r = 0.126, P = 0.268, respectively). In receiver operating characteristics curve analysis, the cut-off value of MPV levels was > 8.7 fl and had 82% sensitivity and 63% specificity in predicting pulmonary artery hypertension., Conclusion: In the present study, we found that MPV levels, an indicator of platelet activation, were significantly higher in patients with ASD and correlated with systolic pulmonary artery pressure and right ventricular diameter.

We evaluated the association of total bilirubin with post-percutaneous coronary intervention (PCI) coronary blood flow and in-hospital major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. A total of 536 consecutive patients with STEMI (male 79%, mean age = 59.9 ± 12.6 years) admitted within 6 hours from symptom onset were enrolled. Patients were divided into 2 groups based on the thrombolysis in myocardial infarction (MI) flow grade. In-stent thrombosis, nonfatal MI, and in-hospital mortality were significantly higher in no-reflow group (P = .007, P = .002, and P < .001, respectively). On multivariate regression, the total bilirubin levels remained independent predictors of no-reflow (odds ratio [OR] 1.586, 95% confidence interval [CI] 1.02-2.47; P = .042) and in-hospital MACE (OR 1.399, 95% CI 1.053-1.857; P = .020). Serum bilirubin levels were independently associated with no-reflow and in-hospital MACE in patients with STEMI undergoing primary PCI.

We studied 403 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI). This population was divided into tertiles according to the SYNTAX score (SXscore). The high SXscore group was defined as an SXscore ≥13, and the low SXscore group as an SXscore <13. The total bilirubin (sTB) and direct bilirubin levels of patients were significantly higher in the high SXscore group (P = .001 and P = .007, respectively). There was a correlation between sTB and SXscore (r = .495; P = .005). On multivariate linear regression analyses, age (β = .100; P = .041), sTB levels (β = .171; P = .005), low-density lipoprotein cholesterol (β = .121; P = .014), and troponin-I (β = .124; P = .011) remained independent correlates of high SXscore. The mean follow-up period was 18.2 months. All-cause mortality rate was higher in the high SXscore group but did not reach significance (P = .058). In conclusion, high sTB level is independently associated with severity of coronary artery disease in patients with NSTEMI. However, no association was found with long-term mortality.
