    ABSTRACT: Chronic total occlusion (CTO) in a noninfarct-related artery (non-IRA) is an independent predictor of mortality in acute coronary syndrome (ACS). Mean platelet volume (MPV) and serum uric acid (SUA) are associated with cardiovascular events in ACS. We investigated the relationship between the presence of non-IRA-CTO with MPV and SUA levels in patients with ACS. Patients (n = 1024) who underwent urgent coronary angiography for ACS were included in this study. Blood samples were drawn on admission. Patients were categorized into 2 groups: non-IRA-CTO (-) and non-IRA-CTO (+). The MPV and SUA levels on admission were significantly higher in the non-IRA-CTO (+) group than in the non-IRA-CTO (-) group (P < .001). At multivariate analysis, MPV (odds ratio [OR]: 4.705, P < .001) and SUA (OR: 2.535, P < .001) were independent predictors of non-IRA-CTO together with age, hemoglobin, ejection fraction, and non-ST-segment elevation ACS. The MPV and SUA levels were significant and independent predictors for the presence of non-IRA-CTO in patients with ACS.

    ABSTRACT: N-terminal pro-brain natriuretic peptide (NT-proBNP) levels are associated with short- and long-term mortality in acute coronary syndrome (ACS). We investigated whether baseline NT-proBNP levels are associated with burden of coronary atherosclerosis assessed by SYNTAX score (SXScore). We enrolled 509 patients with ACS who underwent coronary angiography. The patients were divided into tertiles according to the SXScore: low SXScore (≤22), intermediate SXScore (23-32), and high SXScore (≥33). The NT-proBNP levels demonstrated an increase from low SXScore tertile to high SXScore tertile. The NT-proBNP levels according to the SXScore tertiles are as follows: low and intermediate (median 635 vs 1635, P = .014), low and high (median 635 vs 4568, P < .001), and intermediate and high (median 1635 vs 4568, P < .001). In multivariate analysis, NT-proBNP remained an independent predictor of high SXScore (odds ratio: 2.688, 95% confidence interval: 1.315-5.494, P = .007) together with age (P = .002), neutrophil-lymphocyte ratio (P = .017), and presence of non-ST-segment elevation ACS (P = .002). The NT-proBNP was independently associated with burden of coronary atherosclerosis in patients with ACS.

    ABSTRACT: We investigated the relationship between red cell distribution width (RDW) and contrast-induced nephropathy (CIN) in patients (aged 61 ± 12, 69% men) with acute coronary syndrome (ACS). Consecutive patients diagnosed with ACS (n = 662) who underwent percutaneous coronary intervention (PCI) were included in the study. Patients were divided into 2 groups: CIN and no CIN. Contrast-induced nephropathy was defined as an increase in serum creatinine level of ≥0.5 mg/dL or ≥25% above baseline within 72 hours after PCI. Contrast-induced nephropathy occurred in 81 (12.2%) patients. Red cell distribution width, creatinine, and high-sensitivity C-reactive protein levels were significantly higher in the CIN group than in the no-CIN group. Multivariate regression analysis revealed that baseline RDW level (odds ratio 1.379, 95% confidence interval 1.084-1.753, P = .009), age (P = .025), creatinine (P = .004), and left ventricular ejection fraction (P = .011) were independent risk factors for the development of CIN. In conclusion, increased RDW levels are independently associated with a greater risk of CIN in patients undergoing PCI for ACS.

    ABSTRACT: Impaired coronary flow after primary percutaneous coronary intervention (PPCI) is associated with short- and long-term morbidity and mortality in patients with acute ST-segment elevation myocardial infarction (STEMI). Recent studies have demonstrated that platelet-to-lymphocyte ratio (PLR) is associated with adverse cardiovascular outcomes. The aim of this study was to assess the relation between admission PLR and angiographic reflow after PPCI. A total of 520 patients with acute STEMI (age 60 ± 13 years; 74% men) occurring within 12 hours of the onset of symptoms who underwent PPCI were enrolled. The PLR and other laboratory parameters were measured before PPCI. The patients were divided into 2 groups based on the postintervention Thrombolysis in Myocardial Infarction (TIMI) flow grade: normal-reflow group (defined as postintervention TIMI grade 3 flow) and none-reflow group (consisted of both patients with angiographic no-reflow defined as postintervention TIMI grades 0 to 1 flow and slow flow defined as postintervention TIMI grade 2 flow). There were 117 patients (22.5%) in the none-reflow group (age 68 ± 13 years and 77% men) and 403 patients in the normal-reflow group (age 58 ± 12 years and 63% men). The none-reflow group had significantly higher PLR compared with the normal-reflow group (219 ± 79 vs 115 ± 59, p <0.001). In logistic regression analysis, PLR (odds ratio 1.818, 95% confidence interval 1.713 to 1.980, p <0.001) and total stent length (OR 1.052, confidence interval 1.019 to 1.086, p = 0.002) were independent predictors of none-reflow after PPCI. In conclusion, preintervention PLR is a strong and independent predictor of slow flow/no-reflow after PPCI in patients with acute STEMI.

    ABSTRACT: Abstract Increased red cell distribution width (RDW) is closely related to the poor prognosis and adverse events of cardiovascular diseases. We aimed to investigate the association of serum RDW levels and in-stent restenosis (ISR) after coronary stenting with bare-metal stent in patients with stable coronary artery disease. A total of 251 patients (age 62 ± 11 years, 69% male) with a history of coronary stenting who underwent control coronary angiography (128 with ISR and 123 without ISR) were enrolled into the study. Laboratory parameters were measured before angiography. ISR was defined as luminal stenosis ≥50% within the stent or within 5 mm of its edges by the quantitative coronary analysis. The patients were divided into the two groups: ISR group and no-ISR group. Baseline characteristics of the patients were similar. The ISR group had significantly higher RDW levels compared with patients in no-ISR group (14.47 ± 1.37 vs. 13.59 ± 0.88, p < 0.001). Furthermore, the ISR group had significantly longer stent length and lower stent diameter when compared to no-ISR group (p = 0.001 and p = 0.004, respectively). In a multivariate analysis, RDW levels >13.75%, high-sensitivity C-reactive protein levels, stent diameter and stent length were independently associated with ISR [odds ratio (OR) = 2.12, 95% confidence interval (CI) = 1.71-3.15, OR = 2.80, 95% CI = (1.34-4.61), OR = -2.60, 95% CI = -(1.19-4.51), OR = 2.02, 95% CI = 1.99-3.76, p = 0.001, respectively]. We concluded that increased serum RDW levels were independently associated with bare-metal ISR in patients with stable coronary artery disease.

    ABSTRACT: Background Contrast-induced nephropathy (CIN) is associated with significantly increased morbidity and mortality after percutaneous coronary intervention (PCI). Patients with acute coronary syndrome (ACS) are at higher risk for CIN. N-terminal pro-brain natriuretic peptide (NT-proBNP) is closely linked to the prognosis as a strong predictor of both short- and long-term mortality in patients with ACS.HypothesisWe hypothesized that NT-proBNP levels on admission can predict the development of CIN after PCI for ACS.MethodsA total of 436 patients (age 62.27 ± 13.01 years; 64.2% male) with ACS undergoing PCI enrolled in this study. Admission NT-proBNP levels were measured before PCI. Serum creatinine values were measured before and within 72 hours after the administration of contrast agents. Patients were divided into 2 groups: CIN group and no-CIN group. CIN was defined as an increase in serum creatinine level of ≥0.5 mg/dL or ≥25% above baseline within 72 hours after contrast administration.ResultsCIN developed in 63 patients (14.4%). Baseline NT-proBNP levels were significantly higher in patients who developed CIN compared to those who did not develop CIN (median 774 pg/mL, interquartile range 177.4–2184 vs median 5159 pg/mL, interquartile range 2282–9677, respectively; P < 0.001). Multivariate analysis found that NT-proBNP (odds ratio [OR]: 3.448, 95% confidence interval [CI]: 1.394-8.474, P = 0.007) and baseline creatinine (OR: 6.052, 95% CI: 1.860-19.686, P = 0.003) were independent predictors of CIN.Conclusions Admission NT-proBNP level is an independent predictor of the development of CIN after PCI in ACS.

    ABSTRACT: Low serum albumin (SA) levels are associated with increased cardiovascular mortality. We investigated whether baseline SA levels are associated with no-reflow following primary percutaneous coronary intervention (pPCI). A total of 536 patients (aged 60 ± 13 years; 74% men) who underwent pPCI were enrolled. The patients were divided into 2 groups: no-reflow and normal-reflow. No-reflow was defined as thrombolysis in myocardial infarction ≤2 flow. Admission SA levels were significantly lower in the no-reflow group than in the normal-reflow group (3.55 ± 0.44 vs 4.01 ± 0.32 mg/dL, P < .001). Also, high-sensitivity C-reactive protein (hsCRP), creatinine, creatine kinase myocardial band isoenzyme, and troponin T were significantly higher while hemoglobin and left ventricular ejection fraction (LVEF) were significantly lower in the no-reflow group. In multivariate analysis, SA level remained an independent predictor of angiographic no-reflow (odds ratio 0.114, 95% confidence interval 0.032-0.405, P = .001) together with LVEF, hsCRP, and baseline culprit artery patency. Admission SA level was an independent predictor of no-reflow after pPCI.

    ABSTRACT: The Syntax score (SXscore) is an anatomic scoring system based on the coronary angiography (CA), which not only quantifies lesion severity and complexity, but also predicts poor cardiovascular outcomes including mortality in patients with acute coronary sydromes (ACS). Recent studies have shown that platelet-to-lymphocyte ratio (PLR) is associated with worse outcomes in many cardiovascular diseases. We sought to investigate the association of PLR with severity and complexity of coronary atherosclerosis as assessed by the SXscore in patients with ACS undergoing urgent CA. A total of 1016 patients with ACS undergoing urgent CA were included into the study between August 2012 and March 2014. Admission PLR values were calculated before CA. The SXscore was determined from baseline CA. The patients were divided into two groups as low SXscore (≤22) and intermediate-high SXscore (≥23). The PLR was significantly higher in patient with intermediate-high SXscore compared with low SXscore (P<0.001). In-hospital mortality was significantly higher in high PLR and intermediate-high SXscore groups. In multivariate analysis, the independent predictors of intermediate-high SXscore were PLR (OR:1.018, 95% CI:1.013-1.023, P < 0.001) together with left ventricular ejection fraction (OR:0.935, 95% CI:0.910-0.960, P<0.001), and age (OR: 1.029, 95% CI:1.029-1.054, P=0.02). A PLR ≥116 had a 71% sensitivity and 66% specificity in predicting intermediate-high SXscore. In conclusion, the PLR at admission is significantly associated with the severity and complexity of coronary atherosclerosis in patients with ACS. Increased PLR is an independent predictor of higher SXscore in patients with ACS underwent urgent CA.

    ABSTRACT: Reduced baseline coronary flow in an infarct-related artery (IRA) before a primary percutaneous coronary intervention (PPCI) increases mortality in patients with ST-elevation myocardial infarction (STEMI). Increased neutrophil/lymphocyte (N/L) ratio has been linked to poor clinical outcomes in patients with STEMI. We investigated whether the N/L ratio, as measured at admission, was associated with IRA patency before mechanical reperfusion in patients with STEMI undergoing PPCI. A total of 404 patients who had undergone PPCI on a single culprit artery were enrolled in this study. According to thrombolysis in myocardial infarction (TIMI) flow grade in the IRA before PPCI, the study population was divided into two groups as TIMI 0 or 1 group (occluded IRA) and TIMI 2 or 3 group (patent IRA). The N/L ratios were found to be significantly higher in the TIMI flow 0/1 group when compared with the TIMI flow 2/3 group (6.08±3.94 vs. 4.01±2.87, P=0.001). The absence of early IRA patency was associated with higher Syntax score, mean platelet volume, creatine kinase-myocardial band, and troponin T levels (P=0.0001, P=0.03, P<0.001, and P=0.004, respectively), and lower left ventricular ejection fraction (P=0.02). Multivariate logistic regression analysis showed that the N/L ratio and Syntax score were independent predictors of IRA patency (odds ratio: 1.89, 95% confidence interval: 1.82-1.98; odds ratio=2.80, 95% confidence interval: 1.75-3.86, respectively; P=0.001). The N/L ratio has been found to be associated independently with early IRA patency before PPCI in patients who have undergone PCI for STEMI. This simple and cheap parameter can provide useful information on the related risk evaluation in these patients.

    ABSTRACT: Abstract Backgrounds: Little is known about the effect of the estimated glomerular filtration rate (eGFR) on the periprocedural myocardial infarction (PMI). The aim of this study was to determine an eGFR value that is related with PMI development in patients with stable angina undergoing elective percutaneous coronary intervention (PCI). Method: A retrospective analysis was conducted of 257 consecutive PCI patients with stable angina pectoris. The patients were divided into three groups according to eGFR: Group 1: eGFR > 90 mL/min/1.73 m(2), Group 2: eGFR = 60-89 mL/min/1.73 m(2), and Group 3: eGFR = 30-59 mL/min/1.73 m(2). Cardiac biomarkers were measured before, at 8, and at 24 h after the procedure. Results: Periprocedural myocardial infarction occurred in 19% of the study patients. The frequency of PMI was 13.8% in group 1, 15.2% in group 2, and 35% in group 3 (p = 0.002). There was an inverse relationship with increasing cardiac biomarkers and decreasing eGFR values. Multiple regression analysis showed that an eGFR value between 30 and 59 mL/min/1.73 m(2) was an independent variable that significantly affected PMI development after PCI. Conclusions: An estimated glomerular filtration rate between 30 and 59 mL/min/1.73 m(2) is a predictor of developing PMI after elective PCI in patients with stable angina pectoris.

    ABSTRACT: Purpose: In this study, we aimed to investigate the relationship between saphenous vein graft disease (SVGD) and neutrophil-to-lympocyte ratio (NLR) with other possible confounding factors. Methods: A total of 120 patients were enrolled into the present study. Of all participants, 40 patients were with SVGD and 80 of them were with patent SVG. Results: The NLR, white blood cell (WBC) count, age of SVG, red cell distribution width (RDW), and mean platelet volume were significantly higher in the SVGD group. In regression analysis, NLR, WBC, RDW, and age of SVG remained as independent predictors of SVGD.Conclusion: To our knowledge, we showed for the first time that NLR is independently associated with SVGD. It can be easily used in this era, because it is easily available, widely used, and relatively cheap. Besides NLR, WBC count, SVG age, and RDW can also be used to predict SVGD.

    ABSTRACT: We aimed to elucidate the relationship between mild to moderate renal impairements and burden of atherosclerosis in patients with acute coronary syndrome (ACS). A total of 380 patients with ACS were included in the study. Gensini and SYNTAX scores were also calculated. Kidney function was classified based on estimated glomerular filtration rate (eGFR) into stage 1: eGFR >90, stage 2: 60 to 89, and stage 3: 30 to 60 mL/min per 1.73 m(2). Gensini and SYNTAX scores were higher in stages 2 and 3 than in stage 1. Also, the number of diseased vessels, number of critical lesions (>50 and 70%), left main disease, and number of total occlusion vessels were higher in stages 2 and 3 than in stage 1. Multivariate linear regression analysis demonstrated that a decreased eGFR was an independent risk factor for SYNTAX and Gensini scores together with age and male gender.

    ABSTRACT: Background and aims To evaluate the anxiety, depression and related psychogenic erectile dysfunction that might be developed before and after pacemaker implantation in patients with cardiac arrhythmias. Material and methods Thirty permanent pacemaker implanted male patients, were enrolled to study between September 2006 and September 2008. Erectile function domain questions of International Index of Erectile Function (IIEF-6) and Hospital Anxiety and Depression Scale (HAD) questionnaires were applied to patients, 6 months before pacemaker implantation (BP6) and on month 1 (AP1) and 6 after application (AP6). Patients were included in a multidisciplinary cardiac rehabilitation-adaptation program with a duration of 1-2 months. Patients were evaluated in subgroups. Results Mean age was 51.5 ± 10.3. Most frequent diagnosis was observed as AV block in etiology. The mean IIEF values were changed 22.8→20.2→24.6 in BP6, AP1 and AP6 time frames consecutively. However, the mean HAD-Anxiety scores were evaluated as 8.1→17.0→7.3 and the mean HAD-Depression as 3.9→7.9→8.9 consecutively in the same time frames. Conclusion Cardiac arrhythmia plus permanent pacemaker implantation, increased anxiety and depression of patients and decreased erectile function at AP1; however, the improvement in cardiac symptoms at AP6 with the possible positive effects of rehabilitation program, helps to reduce anxiety and increased IIEF scores, although there was still a slight increase in depression levels.

    ABSTRACT: Platelets play a central role in the pathophysiology of coronary artery disease (CAD). Increased mean platelet volume (MPV) is an indicator of platelet function and associated with poor clinical outcome in patients with acute coronary syndrome (ACS). We evaluated the relationship between MPV and severity of CAD in patients with ACS. A total of 395 patients with ACS were included. Severity of CAD was assessed with the Gensini and Syntax scores. High levels of MPV were associated with the Gensini and Syntax scores, number of diseased vessels (>50%), number of critical lesions (>50% and >70%), and noncritical lesions. After multivariate analysis, high levels of MPV were independent predictors of multivessel CAD together with age. In patients with ACS, high MPV levels were associated with severity of CAD. It is possible that MPV can be a helpful marker in patients with CAD for the severity of coronary atherosclerosis.

    ABSTRACT: A 72 year-old woman was admitted with a one-week history of weakness, right limb pain and progressive breathlessness. Her blood pressure was 60/40 mmHg, ECG showed inverted T waves in the precordial leads and incomplete right bundle branch block (RBBB). Transthoracic echocardiography revealed a large serpentine mobile mass across the atrial septum and mitrale valve extending into the left ventricular cavity. The right ventricle was dilated and peak systolic tricuspid annular velocity (RV-Sm) was 6.5 cm/sn, indicate right ventricular systolic function was severely depressed. Transoesophageal echocardiography showed a large, mobile thrombus in the foramen ovale, extending into the left atrium and ventricle. As the patient was in a haemodynamically compromised condition, high dose rapid infusion of streptokinase was administered. However, the thrombus did not fully resolve with this intervention. Therefore, low dose continuous streptokinase infusion was administered for an additional 72 h resulting in full resolution of the lesion by the third day of therapy. The optimal management of impending paradoxical embolism remains unclear. Prolonged continuous thrombolytic infusion may be a option for patients who do not experience full resolution of high risk thrombi with conventional thrombolytic therapy.

    ABSTRACT: Many cases of coronary artery spasm during regional or general anesthesia have been reported. To our knowledge, for the first time we report a case of coronary artery spasm induced by general anesthesia that was documented by immediate angiography and treated with intracoronary nitroglycerine. A 68-year-old female was to undergo elective cholecystectomy. General anesthesia was induced by propofol 140 mg, fentanyl 50 microg, and vecuronium bromide 7 mg. Immediately after intubation sudden hypotension (60/40 mmHg) and marked ST-segment elevation on the monitor were noticed. A 12-lead electrocardiogram demonstrated marked ST-segment elevations in inferior leads with reciprocal changes. An immediate diagnostic coronary angiography showed diffuse severe narrowing of the right coronary artery with a non-critical plaque in the midportion. After intracoronary administration of nitroglycerine 0.2 mg into the right coronary artery, there was marked diffuse vasodilatation. A diagnosis of variant angina was made and 2 days of hospital course was uneventful. The patient was discharged taking diltiazem 120 mg two times daily, aspirin 100 mg daily and isosorbidemononitrate 60 mg daily.

    ABSTRACT: Air ambulance system has been established throughout the country by the Ministry of Health of Turkey. Fifteen provinces are determined as centers of the system so that all the country is covered within at the most one-hour flight distance. As part of this nationwide system, two helicopter ambulances have been deployed in our hospital since October 2008. Prompt use of reperfusion therapy improves survival of patients sustaining acute myocardial infarction (AMI). Two components of delay from the onset of AMI to reperfusion therapy are prehospital and interhospital transportations. We presented the first two cases of AMI whose transfers were made by a helicopter ambulance for primary percutaneous coronary intervention. One patient (age 58 years, male) presented to a state hospital 47 km away from Ankara about an hour after the onset of chest pain. Time to reach the patient by a helicopter ambulance was 28 minutes and transfer to our center was 14 minutes. The other patient (age 76 years, male) was admitted within 15 minutes of the onset of chest pain to a state hospital 58 km away from Ankara. Reaching the patient by a helicopter ambulance and transferring him to our center took 30 minutes and 16 minutes, respectively. Door-to-balloon times were 16 minutes and 18 minutes, respectively. Infarct-related coronary artery patency was achieved in both cases.

    ABSTRACT: Ivabradine is the first specific heart rate-lowering agent that has completed clinical development for stable angina pectoris. The aim of the present study was to investigate the effects of ivabradine therapy on P-wave duration, dispersion and QT duration, dispersion in coronary artery disease patients. The study population consisted of 21 patients with CAD who have confirmed by coronary angiography previously. Written informed consent was obtained in all patients. Twelve-lead electrocardiogram was recorded for each subject at a rate of 50mm/s on admission and repeated after 1 month ivabradine therapy. QT duration, QT dispertion, maximum and minimum QT duration calculated. Maximum and minimum P wave and P wave dispersion has been calculated. Heart rate was decreased after ivabradine therapy. (75+/-15 and 63+/-10, P=0.02).There was no difference between Pmax, Pmin and Pdis values before and after treatment. QTmax value was prolonged after treatment. (410+/-43 and 431+/-14, P=0,005) but there was no difference between cQTmax value.(455+/-38 and 439+/-21) There was no difference between QTdis and cQTdis values before and after treatment. (44+/-18 & 49+/-14; and 49+/-22 & 48+/-15). QTmax was prolonged after ivabradine therapy but cQTmax, Pdis, QTdis and cQTdis were not prolonged. There is no relationship between ivabradine therapy and increased risk of ventricular and atrial arrhythmia in coronary artery disease patient.
