Endoscopic Thoracic Sympathectomy in the Treatment of Vasospastic Angina Resistant to Medical Therapy.

BACKGROUND: In this study, we aimed to investigate the clinical follow-up results of endoscopic thoracic sympathectomy (ETS) in the treatment of vasospastic angina (VSA) resistant to maximal medical therapy. METHODS: A total of 80 patients with VSA who presented to our hospital between 2010 and 2022 were included in our study. Among them, 6 patients who did not respond to medical therapy underwent ETS. In-hospital and long-term clinical outcomes of patients who underwent ETS were recorded. RESULTS: The median age of the patients with VSA was 57 [48-66] years, and 70% of the group were males. In the ETS group, compared to the non-ETS group, higher numbers of hospital admissions and coronary angiographies were observed before ETS (median 6 [5-6] versus 2 [1-3], P <.001; median 5 [3-6] versus 2 [1-3], P =.004, respectively). Additionally, while 2 patients (33.3%) in the ETS group had implantable cardioverter defib-rillator (ICD), only 2 patients (2.7%) in the non-ETS group had ICD (P =.027). Out of the 6 patients who underwent ETS, 2 were females, with a median age of 56 [45-63] years. Four patients underwent successful bilateral ETS, while 2 patients underwent unilateral ETS. During the follow-up period after ETS, only 3 patients experienced sporadic attacks (once in 28 months, twice in 41 months, and once in 9 years, respectively), while no attacks were observed in 3 patients during their median follow-up of 7 years. CONCLUSION: It appears that ETS is effective in preventing VSA attacks without any major complications.

The Effect of Anesthesia Type Applied in Transcatheter Aortic Valve Implantation.

OBJECTIVE: Different results have been obtained in studies on the effect of anesthesia type applied during transcatheter aortic valve implantation on in-hospital outcomes. In this study, we aimed to investigate the association of the type of anesthesia with the lenght of stay in the intensive care unit and the need for inotropes in patients undergoing transcatheter aortic valve implantation. METHODS: A total of 140 patients who underwent transcatheter aortic valve implantation between January 2016 and January 2022 were retrospectively analyzed. The patients were divided into 2 groups as deep sedation and general anesthesia according to the type of anesthesia. RESULTS: The mean age of all patients was 78.5 ± 8.6 years, and 69 of the patients (49.3%) were female. Length of stay in intensive care unit, midazolam dosage, use of inotropic agents, and procedural hypotension were significantly lower in the deep sedation group than in the general anesthesia group [(1[1-2] vs. 1[1-2.5] days, P = 0.03), (2.1 ± 0.4 mg/kg vs. 2.3 ± 05, P = 0.02), (39 (37.9%) vs. 22 (59.5%), P = 0.02), (41 (39.8%) vs. 25 (67.6%), P = 0.004)]. General anesthesia was associated with increased use of inotropic agents during transcatheter aortic valve implantation compared to deep sedation (odds ratio = 2.93 95% CI = 1.18-7.30, P = 0.02). CONCLUSION: The use of inotropes is less in transcatheter aortic valve implantation procedures performed under deep sedation and length of stay in intensive care unit is shorter.

The Role of Prophylactic Ipsilateral Distal Femoral Artery Cannulation in Preventing Periprocedural Peripheral Complications During Transcatheter Aortic Valve Implantation.

OBJECTIVE: Access site-related vascular complications are common complications of trans- catheter aortic valve replacement. In this study, we aimed to investigate the efficacy and safety of prophylactic cannulation of the ipsilateral distal femoral artery in the management of access site-related vascular complications. METHODS: One hundred sixty-four patients, who were evaluated by the Heart Team of our institution and found eligible for transcatheter aortic valve replacement procedure between January 2016 and August 2019, were included in this retrospective study. Patients were divided into two groups according to the management of peripheral complications. The antegrade crossover was used as bailout treatment in the first 70 patients. Prophylactic cannulation of the ipsilateral distal femoral artery was performed in the last 94 patients. These 2 groups were compared. RESULTS: Peripheral complications developed in 15 of the first 70 patients included in the study. The percutaneous intervention was unsuccessful in 4 of the patients who underwent bailout antegrade crossover. Peripheral complications developed in 14 of the last 94 patients in whom prophylactic cannulation of the ipsilateral distal femoral artery was performed, and all these patients were managed successfully with percutaneous intervention. CONCLUSION: Prophylactic cannulation of the ipsilateral distal femoral artery is a simple, effec- tive, and safe method in the management of access site-related vascular complications.

Effects of RAAS blocker use on AKI in elderly hypertensive STEMI patients with propensity score weighed method.

Studies reported conflicting results on the effect of renin-angiotensin-aldosterone system (RAAS) blocker use on acute kidney injury (AKI) in patients undergoing elective coronary angiography but association in elderly patients with ST-elevation myocardial infarction (STEMI) is not known. Also, there are limited data on the effect of inflammatory markers on AKI. We aimed to investigate the effects of RAAS blocker pretreatment and inflammatory markers on AKI in this population. A total of 471 patients were compared according to presence of RAAS blocker pretreatment at admission. Conventional and inverse probability weighed conditional logistic regression were used to determine independent predictors of AKI. Mean age of the study group was 75.4 ± 7.1 years and 29.1% of the patients were female. AKI was observed in 17.2% of the study population. Weighted conditional multivariable logistic regression analysis revealed that AKI was associated with baseline creatinine levels and C-reactive protein/albumin ratio (CAR) (OR 2.08, 95% CI = 1.13-3.82, p = .02 and OR 1.19, 95% CI = 1.01-1.41, p = .04, respectively). No significant association was found between RAAS blocker pretreatment and AKI. CAR and elevated baseline creatinine levels were independent predictors of AKI in this patient group.

Successful Usage of FlexCath Steerable Catheter in Case of Atrial Septal Closure Device Comes Perpendicular to Interatrial Septum.

OBJECTIVE: Percutaneous closure of atrial septal defects is challenging in cases where the device is perpendicular to the septum during the procedure. Hence, different techniques, maneuvers, and auxiliary equipment may be required. We aimed to demonstrate the effectiveness of the FlexCath steerable catheter application in percutaneous closure of atrial septal defect cases in which the device was perpendicular to the septum. METHODS: Patients with atrial septal defect who presented to our clinic between January 2017 and December 2020 and were deemed eligible for percutaneous closure were included in the study. RESULTS: Atrial septal defects of 101 patients out of 110 patients were successfully closed using standard methods. Nine patients in whom it was seen if the device was perpendicular to the interatrial septum were successfully closed with FlexCath steerable catheter support. There was no statistically significant difference between patients in terms of age, gender, floopy rim, and multiple defects. In the group that was treated with FlexCath steerable catheter support, the aortic rim was smaller, and the defect diameter and the size of the atrial septal defects device were larger. The success of the procedure was 100% while using the flexcath steerable catheter in patients with the device perpendicular to the interatrial septum. There were no complica tions during the procedure. CONCLUSION: Percutaneous closure with FlexCath steerable catheter support in difficult cases with atrial septal defects was effective in those with the atrial septal closure device being per pendicular to the interatrial septum and was performed easily without any safety issues.

C-Reactive Protein/Albumin Ratio Predicts Acute Kidney Injury in Patients With Moderate to Severe Chronic Kidney Disease and Non-ST-Segment Elevation Myocardial Infarction.

In this study, we aimed to evaluate the predictive value of admission C-reactive protein/albumin ratio (CAR) for acute kidney injury (AKI) in cases with moderate to severe chronic kidney disease (CKD) not on dialysis who presented with non-ST-segment elevation myocardial infarction (NSTEMI) and underwent coronary angiography (CAG). This cross-sectional and observational study included 420 NSTEMI patients. The study population was categorized based on the CAR tertiles as groups T1, T2, and T3. The primary outcome of the study was AKI development; 92 (21.9%) cases developed AKI. The frequency of AKI was significantly higher in the T3 group compared with the T2 and T1 groups (34% vs 17% vs 14%, P < .001). Age, estimated glomerular filtration rate, contrast media volume, and CAR (odds ratio: 1.36; 95% CI: 1.17-1.57; P < .01) were significant predictors of AKI. In a receiver operating characteristic curve analysis, CAR levels >0.20 predicted AKI development with a sensitivity of 74% and a specificity of 45%. We observed that the CAR may be a promising inflammatory parameter for AKI in NSTEMI patients with moderate to severe CKD after CAG.

Association of ectatic non-infarct-related artery with 1-month stent thrombosis in patients with ST elevation myocardial infarction.

BACKGROUND: Ectatic infarct-related artery (IRA) has been shown to be associated with higher thrombus burden, no-reflow, stent thrombosis (ST) and major adverse cardiovascular events in patients with ST-elevation myocardial infarction (STEMI). The effect of ectatic non-IRA on ST without ectatic IRA is not known. We aimed to assess the effect of ectatic non-IRA presence on ST within 1 month after primary percutaneous intervention (pPCI) in patients with STEMI. METHODS: A total of 1541 patients with a diagnosis of STEMI and underwent pPCI between 2015 and 2020 were retrospectively included in the study. Patients with and without 1 month ST were compared. Penalised logistic regression method was used to assess the association between ST and candidate predictors due to the risk of overfitting. RESULTS: Median age of the study group was 56.5 (48.7 to 67.2) years. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score, ectatic non-IRA presence and use of tirofiban were significantly higher in the ST group (18.2±9.9 vs 15.1±9.9, p=0.03; 25% vs 7.2%, p<0.001; 54.2% vs 30.5%, p<0.001; respectively). Significantly higher thrombus aspiration (14.3% vs 6.7%, p=0.03) and lower stent implantation (67.7% vs 84%, p<0.001) rates were observed in ectatic IRA group compared with ectatic non-IRA group. In multivariable analysis, ectatic non-IRA presence was independently associated with 1-month ST (OR 4.01, 95% CI 1.86 to 8.63, p=0.01). CONCLUSION: Ectatic non-IRA presence without ectatic IRA in patients with STEMI increases the risk of ST within the first month of pPCI.

Post percutaneous coronary intervention hemoglobin levels predict in-hospital mortality in patients with STEMI treated with primary percutaneous coronary intervention.

OBJECTIVE: In this study, we aimed to determine whether admission hemoglobin versus post-percutaneous coronary intervention (PCI) hemoglobin level at 24 hours is a predictor of in-hospital mortality for patients with ST elevation myocardial infarction (STEMI) without evidence of clinical hemorrhage who underwent primary PCI. METHODS: In this study, we included 1,444 consecutive patients with STEMI who underwent primary PCI at a tertiary heart hospital. The primary outcome of the study was the in-hospital all-cause mortality. We used the penalized maximum likelihood estimation (PMLE) logistic regression method to examine the relationship between primary outcome and candidate predictors. RESULTS: In total, 172 (11.9%) patients died during the in-hospital course. According to a PMLE logistic regression analysis, age, KILLIP class ≥2, pre-PCI thrombolysis in myocardial infarction (TIMI) flow <3, systolic blood pressure, creatinine, glycoprotein IIb/IIIa inhibitor use, and post-PCI hemoglobin levels at 24 hours were predictors of in-hospital mortality. The relative importance of post-PCI hemoglobin at 24 hours (contributing 6% of the explainable outcome in the model) was significantly higher than admission hemoglobin (contributing only 0.1% of the explainable outcome in the model). CONCLUSION: This study demonstrated that post-PCI hemoglobin levels were independently associated with in-hospital survival in patients with STEMI without evidence of bleeding following primary PCI. In addition, post-PCI hemoglobin was a better predictor of in-hospital mortality than admission hemoglobin for patients with STEMI who underwent primary PCI.

Higher Copeptin Levels are Associated with the Risk of Atrial Fibrillation in Patients with Rheumatic Mitral Stenosis.

BACKGROUND: Correlations between increased copeptin levels and various cardiovascular diseases have been described. In this study, we aimed to investigate the correlation between increased copeptin levels and paroxysmal atrial fibrillation (PAF) in rheumatic mitral stenosis (MS). METHODS: Patients with mild/moderate rheumatic MS and sinus rhythm were consecutively recruited from an echocardiography laboratory. Patients with a history of PAF and those with PAF on 24-48-hour ambulatory electrocardiography (ECG) monitoring constituted the study group, and those without PAF on ambulatory ECG monitoring constituted the control group. Clinical characteristics, echocardiographic parameters and levels of copeptin, plasma N-terminal proBNP (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) were evaluated. RESULTS: Twenty-nine patients with PAF and 124 control MS patients were studied. Patients in the PAF group were older, but the mitral valve areas and transmitral gradients were not different between the groups. In the PAF group, hs-CRP (1.2 vs. 0.8 mg/L, p < 0.001), NT-proBNP (335 vs. 115 pg/mL, p < 0.001) and copeptin (6.9 vs. 4.0 pmol/L, p < 0.001) levels were significantly higher than in the control group. Multivariable logistic regression analysis revealed that age [odds ratio (OR) 1.19, 95% confidence interval (CI) 1.04-1.38; p = 0.024], left atrial volume index (OR 1.23, 95% CI 1.06-1.41; p = 0.032), copeptin levels (OR 2.81, 95% CI 1.30-5.29; p < 0.001) and hs-CRP levels (OR 15.5, 95% CI 1.41-71.5; p = 0.012) were independent predictors of PAF. CONCLUSIONS: In patients with mild/moderate rheumatic MS, higher copeptin and hs-CRP levels predicted a higher risk of developing atrial fibrillation.

In-hospital statin initiation characteristics and one-year statin adherence rates in patients hospitalised for acute coronary syndrome.

INTRODUCTION: In the present study, we aimed to evaluate compliance to lipid lowering guidelines regarding statin prescription on discharge and statin adherence rates during a follow-up period of one year in patients hospitalised with a diagnosis of acute coronary syndrome (ACS). METHODS: In-hospital records of 3506 ACS patients, of which 771 had experienced an ST-elevation myocardial infarction (STEMI) and 2735 had experienced a non-STEMI, were collected. We calculated medication possession ratios (MPRs) for each subject. We designated patients with ≥9 statin refills/year (MPR ≥ 0.75) as the statin-adherent group and patients with <9 statin refills/year (MPR < 0.75) as the statin-non-adherent group. RESULTS: During a 12-month follow-up period, 234 patients in the STEMI group (30.3%) and 391 patients in the non-STEMI group (14.3%) had 12 refills of statin. Thus, only 17.8% of the total study population had complete adherence to statin therapy with an MPR of 1. When patients with ≥9 statin prescriptions were categorised as the statin-adherent group, only 1575 patients (44.9%) were found to be adherent to statin treatment. In multivariate analysis, patients with a non-STEMI diagnosis and high intensity statin treatment had higher rates of non-adherence (OR:1.685, 95%CI:1.412-2.012, p < .01 and OR:1.344, 95% CI: 1.147-1.574, p < .01, respectively). Patients with prior statin treatment had lower rates of non-adherence(OR:0.437, 95%CI: 0.346-0.553, p < .01). CONCLUSION: The present study shows that compliance with guidelines regarding statin initiation during hospitalisation and statin adherence rates during a one-year follow-up period are low for patients treated for ACS. Considering the overwhelming clinical benefits of high-intensity statins in patients with ACS, every effort should be made to increase the rate of optimal use of statins in secondary prevention.

Association of monocyte to high-density lipoprotein ratio with bare-metal stent restenosis in STEMI patients treated with primary PCI.

OBJECTIVE: Monocyte to high-density lipoprotein ratio (MHR) has recently been postulated as a novel parameter related to adverse cardiovascular outcomes. In this study, we aimed to investigate the correlation of MHR with stent restenosis (SR) rates after the primary percutaneous coronary intervention (PCI) and bare-metal stent (BMS) implantation. METHODS: In this study, patients who had undergone primary PCI for STEMI and had a control angiogram during follow-up were retrospectively recruited. Patients were categorized according to admission MHR tertiles, clinical and angiographic data were compared. In addition, predictors of SR were evaluated with logistic regression analysis. RESULTS: A total number of 448 patients (240 patients with SR and 208 patients without SR) were included in this study. Patients were categorized into three groups according to tertiles of admission MHR. During a follow-up period of median 12 months, the rate of SR was significantly higher in patients with higher MHR levels (45% in tertile 1, 54% in tertile 2 and 62% in tertile 3, p<0.01). In multivariate Cox regression analysis, male gender, stent length, admission NLR levels and MHR levels (HR 1.03, 95% CI 1.02-1.06, p<0.01) remained as the independent predictors of SR in the study population. CONCLUSION: Gender, stent length, higher MHR and NLR levels are correlated to SR after primary PCI.

Usefulness of Serum Omentin-1 Levels for the Prediction of Adverse Cardiac Events in Patients with Hypertrophic Cardiomyopathy.

OBJECTIVE: To investigate the association between serum omentin-1 levels and adverse cardiac events in patients with hypertrophic cardiomyopathy (HCM). SUBJECTS AND METHODS: This prospective, observational study included 87 patients with HCM and 50 age- and sex-matched control subjects. Serum omentin-1 and brain natriuretic peptide (BNP) levels were measured in all subjects, using enzyme-linked immunosorbent assay and electrochemiluminescence, respectively. Patients with HCM were divided into 2 groups according to their omentin levels, i.e., low: ≤291 ng/mL (n = 48) and high: > 291 ng/mL (n = 39). Cardiac mortality, hospitalization due to heart failure, and implantable cardioverter-defibrillator (ICD) implantation were considered adverse cardiac events. Statistical analysis included uni- and multivariant logistic regression, receiver-operating characteristic (ROC) analysis, and the Kaplan-Meier method. RESULTS: Serum omentin-1 levels were significantly lower in the obstructive (253.9 ± 41.3 ng/mL) and nonobstructive (301.9 ± 39.8 ng/mL) HCM groups than in the control group (767.1 ± 56.4 ng/mL), p < 0.001, respectively. The BNP levels were higher in the obstructive and nonobstructive HCM groups than in the control group (269.5 ± 220, 241.0 ± 227, and 24.0 ± 18.9 pg/mL, respectively, p < 0.001). The Kaplan-Meier analysis indicated that patients with low omentin-1 levels showed a significantly higher (48.2%) 2-year cumulative incidence of overall adverse cardiac events than those with high omentin-1 levels (16.2%) (log-rank test, p = 0.001). In the multivariate logistic regression analysis, omentin-1, interventricular septum (IVS) thickness, and male gender were independent predictors of adverse cardiac events in the follow-up. CONCLUSION: Omentin-1 levels were lower in patients with HCM than in the control group, and this was associated with worse cardiac outcomes.

Assessment of factors related to statin non-adherence in patients with established coronary artery disease: A single-center observational study.

OBJECTIVE: Lifelong statin treatment is recommended in patients with cardiovascular diseases, but drug adherence is a significant problem. The aim of this study was to investigate factors related to statin discontinuation in high-risk patients with coronary artery disease (CAD) diagnosed by coronary angiography. METHODS: A total of 300 consecutive patients who were followed-up with a diagnosis of CAD were recruited. Patients were categorized as statin adherent or statin non-adherent (patients interrupting statin therapy >30 days). Study participants completed a questionnaire regarding demographic characteristics, medical history, knowledge of statin treatment, and factors related to statin discontinuation. RESULTS: In all, 160 patients (53.3%) were found to be statin adherent. Of those, 122 patients had suffered myocardial infarction, and atorvastatin was the most prescribed statin on discharge. Among the study population, 26% were illiterate and 55% had graduated from primary school. Only 39 cases (13%) cases had a low-density lipoprotein-cholesterol level <70 mg/dL. In 60% of the statin non-adherent patients, the reason for statin discontinuation was physician discontinuation of the statin prescription. In 14%, the patient stopped the therapy after cholesterol parameters had been reduced or reached the normal range. Only 8% of participants reported that negative information received from TV programs and social media was responsible for the decision to terminate drug use. CONCLUSION: Our findings demonstrated that the importance of intensive statin treatment in CAD patients has not been recognized by patients or many physicians. Adherence to statin treatment and success of the therapy is low, leading to unnecessarily high cholesterol levels in patients with CAD.

Higher CHA2DS2-VASc Score Is Associated With Increased Mortality in Acute Pulmonary Embolism.

BACKGROUND: CHA2DS2-VASc score has been validated in risk prediction for stroke and thromboembolism in patients with atrial fibrillation (AF). Association of CHA2DS2-VASc score with higher risk of venous thromboembolism and pulmonary embolism (PE) has also been shown. In this study, we investigated the long-term prognostic value of CHA2DS2-VASc score in patients with acute pulmonary embolism (APE). METHODS: Consecutive patients with APE presenting to our emergency department were retrospectively recruited. Patients with AF and who died secondary to causes other than PE were excluded from the study. The CHA2DS2-VASc score and pulmonary embolism severity index (PESI) were calculated. RESULTS: Two hundred seventy seven participants were included in the study. The mortality rate was 18.7%. Twenty-two cases died within 30 days, and 30 cases died during the follow-up period (median: 13 months). The mean CHA2DS2-VASc score was significantly higher in dead patients compared to survivors (3.61 ± 1.35 vs 1.95 ± 1.52, P < .01). In multivariate regression analysis, systolic pulmonary artery pressure (hazard ratio [HR]: 1.03, 95% confidence interval [CI]: 1.01-1.06, P = .02), PESI score (HR: 1.010, 95% CI: 1.004-1.017, P < .01), and CHA2DS2-VASc score (HR: 1.67, 95% CI: 1.19-2.16, P < .01) were found to be independently correlated with mortality. The patients whose CHA2DS2-VASc score was between 1 and 3 had 5.67 times and patients whose CHA2DS2-VASc score was ≥4 had 16.8 times higher risk of mortality compared to patients with CHA2DS2-VASc score = 0. CONCLUSION: Patients with higher CHA2DS2-VASc scores had higher rates of mortality after APE.

An unexpected complication of acute pancreatitis: Intra-cardiac thrombus.

Left atrial thrombus after acute pancreatitis (AP) is a rare clinical statement. Because of induction of systemic prothrombotic process by AP; some patients with underlying risk factors may develop an intra-cardiac thrombus. We present a 53years-old-woman with moderate mitral stenosis and atrial fibrillation. However the patient was under warfarin treatment, she developed a big left atrial big thrombus which was originated from left atrial appendage after she was suffered from AP.

Assessment of 25-Hydroxyvitamin D Levels in Patients with Resistant Hypertension.

OBJECTIVE: To investigate the possible correlation between serum 25-hydroxyvitamin D levels and resistant hypertension (RH). SUBJECTS AND METHODS: Patients who had undergone ambulatory blood pressure measurements (ABPM) during outpatient controls were enrolled. Fifty subjects with RH, 50 with controlled hypertension (CHT) and 50 normotensive subjects (NT) were included in the study. RH was defined as 'suboptimal blood pressure control despite using 3 antihypertensive agents including a diuretic or need for 4 or more drugs to control blood pressure'. The 25-hydroxyvitamin D and parathormone levels were compared between the groups. Pearson's correlation coefficient test was applied to assess the correlation between 25-hydroxyvitamin D levels and office blood pressure (BP) and ABPM. Logistic regression analysis was used to determine the independent correlates of RH. RESULTS: The 25-hydroxyvitamin D level was significantly lower in the RH group (17.02 ± 5.4 ng/ml) compared to the CHT (24.9 ± 4.8 ng/ml) and NT groups (28.0 ± 5.7 ng/ml, p < 0.001). In univariate correlation analysis, 25-hydroxyvitamin D levels had a significant negative correlation with office systolic BP (r = -0.329, p < 0.001), office diastolic BP (r = -0.395, p < 0.001), systolic ambulatory BP (r = -0.844, p = 0.004), and diastolic ambulatory BP (r = -0.567, p = 0.005). ROC analysis revealed that 25-hydroxyvitamin D levels <21.50 ng/ml predicted the presence of RH with a sensitivity of 78% and a specificity of 79% (AUC = 0.89, 95% CI 0.83-0.94). In the multivariate logistic regression analysis, 25-hydroxyvitamin D level was independently correlated with the presence of RH (ß 0.660, 95% CI 0.572-0.760, p < 0.001). CONCLUSION: There was an independent correlation between lower 25-hydroxyvitamin D levels and presence of RH.

Increased level of red cell distribution width is associated with poor coronary collateral circulation in patients with stable coronary artery disease.

OBJECTIVES: Previous studies have shown the association between various hematological parameters and cardiovascular diseases, and their prognostic value. In this study, we compared red cell distribution width (RDW), neutrophil lymphocyte ratio (NLR) and mean platelet volume (MPV) measurements among patients with poor coronary collateral circulation (CCC) and well-developed CCC. STUDY DESIGN: 326 patients with stable coronary artery disease (CAD) were evaluated retrospectively. CCC was graded by using the Rentrop classification. The poor CCC group included patients with Rentrop 0-1 CCC, and the good CCC group included Rentrop 2-3 CCC. RESULTS: There were 171 subjects (84% male; mean age 56.6±10.4 years) in the poor CCC group, and 155 subjects (89% male; mean age 57.6±9.7 years) in the good CCC group. The total number of vessels with >95% stenosis (1.1±0.5 vs. 1.0±0.4; p=0.64) and Gensini scores (84.4±38.8 vs. 83.3±37.4; p=0.83) was not higher in the poor CCC group compared to the good CCC group. RDW was significantly higher in the poor CCC group compared to the good CCC group (14.19±1.36% vs. 13.89±1.19%; p=0.04). In multivariate logistic regression analysis, elevated levels of RDW and LDL were found to be independent predictors of poor CCC (OR 1.73, 95% CI: 1.30-2.29, p=0.01 and OR 1.01 95% CI 1.002-1.02; p=0.02, respectively). CONCLUSION: In the present study, poor CCC was found to be independently correlated with RDW, but not with any other hematological parameters in patients with stable CAD.
