Misperceptions and management of LDL-cholesterol in secondary prevention of patients with familial hypercholesterolemia in cardiology practice: Real-life evidence from the EPHESUS registry.

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common inherited disease, leading to premature atherosclerotic cardiovascular disease (ASCVD) due to elevated low-density lipoprotein cholesterol (LDL-C) levels. Achieving LDL-C goals is extremely important for preventing the complications of this fatal disease. We evaluated the management of FH patients with ASCVD in cardiology practice. METHODS: We analyzed patients with ASCVD from the nationwide EPHESUS registry, which was conducted in 40 cardiology outpatient clinics, and compared those with and without FH. RESULTS: Of the 1482 consecutively enrolled patients with ASCVD, 618 (41.7%) had FH, among which 455 were categorized as 'Possible FH' and 163 as 'Probable or Definite FH'. Proposed LDL-C goals were not attained in more than 90% of the patients with FH. The proportion of those on statin therapy was 77% for possible and 91% for probable or definite FH, whereas 34.2 % and 59.4% were in use of high-intensity statins, respectively. None of the patients were on PCSK-9 inhibitors, and only 2 used ezetimibe. Adverse media coverage was the most common cause of statin discontinuation (32.5% in 'possible FH' and 45.7% in 'probable/definite FH'). The negative impact of media in the decision to stop lipid lowering therapy (LLT) was increasing with education level. CONCLUSIONS: In real life most of the FH patients with ASCVD are undertreated in cardiology practice regarding statin dosing and combined LLT. Drug discontinuation rates are notably high and are mostly media-related, and side effects very rarely cause cessation of LLT. Urgent measures are needed to increase the awareness of FH among healthcare providers and patients and to develop improved treatment strategies aimed at preventing the complications of FH.

Systemic immune-inflammation index, and neutrophilto-lymphocyte and platelet-to-lymphocyte ratios can predict clinical outcomes in patients with acute coronary syndrome.

OBJECTIVE: Inflammatory mechanisms play an important role in the pathogenesis of atherosclerosis and myocardial infarction. The clinical and prognostic importance of inflammatory parameters, such as neutrophil-lymphocyte (NLR) and platelet-lymphocyte ratios (PLR) in complete blood counts in acute myocardial infarction and other cardiovascular diseases has been demonstrated. However, systemic immune-inflammation index (SII) calculated from neutrophils, lymphocytes and platelets in the complete blood cell count has not been studied sufficiently and is thought to provide a better prediction. This study investigated whether haematological parameters such as SII, NLR and PLR were associated with clinical outcomes in acute coronary syndrome (ACS) patients. METHODS: We included 1 103 patients who underwent coronary angiography for ACS between January 2017 and December 2021. The association between major adverse cardiac events (MACE) that developed in hospital and at 50 months of follow up and SII, NLR and PLR was compared. Long-term MACE were defined as mortality, re-infarction and target-vessel revascularisation. SII was calculated using the formula: NLR × total platelet count in the peripheral blood (per mm3). RESULTS: Of the 1 103 patients, 403 were diagnosed with ST-elevation myocardial infarction and 700 with non-STelevation myocardial infarction. The patients were divided into a MACE and a non-MACE group. In hospital and during the 50-month follow up, 195 MACE were observed. SII, PLR and NLR were found to be statistically significantly higher in the MACE group (p < 0.001). SII, C-reactive protein level, age and white blood cell count were independent predictors of MACE in ACS patients. CONCLUSIONS: SII was found to be a strong independent predictor of poor outcomes in ACS patients. This predictive power was greater than that of PLR and NLR.

The relationship between epicardial adipose tissue thickness and coronary artery disease progress.

BACKGROUND: The relationship between epicardial adipose tissue and inflammatory events has been shown in many studies. Because it is an inflammatory process in coronary progression, it is aimed to examine the relationship between coronary artery disease progression and epicardial adipose tissue thickness. MATERIALS AND METHODS: Our research was conducted with 50 patients (33 men, 17 women) who underwent planned or emergency coronary angiography, by evaluating the coronary artery disease progression from the coronary angiography images together with the echocardiographic epicardial adipose tissue thickness measurement. Patients were examined in two groups according to their tissue thickness, 17 patients with less than 0.55 cm were defined as group 1 and 33 patients with ≥ 0.55 were determined as group 2. RESULTS: There was no significant difference between the groups in terms of gender, diabetes, age, hypertension. In addition, a significant relationship was found with epicardial adipose tissue thickness (> 0.5 cm), ejection fraction and smoking in the group with coronary progression. Patients without stenotic changes were found to be statistically significantly lower p < 0.005. CONCLUSION: An independent relationship was found between epicardial adipose tissue and coronary artery progression. In the light of these findings, it can be concluded that epicardial adipose tissue residue is effective in the development of coronary artery stenosis and calcific-atherosclerotic changes in the coronary arteries. In the light of the information obtained, a positive correlation was determined between epicardial adipose tissue thickness and coronary artery disease (Tab. 3, Fig. 2, Ref. 15).

Relationship Between Atrial Fibrillation and Controlling Nutritional Status Score in Acute Ischemic Stroke Patients.

OBJECTIVE: To determine the relationship between nutritional status evaluated via the COntrolling NUTritional Status (CONUT) score and in-hospital mortality in acute ischemic stroke (AIS) patients. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Cardiology, University of Health Sciences, Sancaktepe Sehit Prof. Ilhan Varank Training and Research Hospital, Turkey, between September 2019 and January 2022. METHODOLOGY: Four hundred and seventy-one consecutive patients with AIS (age 18-90 years) were retrospectively enrolled. Exclusion criteria were age under 18 years, changes in inflammatory or immune markers other than a cerebrovascular event (e.g., autoimmune diseases, sepsis, trauma, recent major surgery, active malignancy), glomerular filtration rate <30 ml/min, severe hepatic failure, receiving thrombolytic therapy, paroxysmal atrial fibrillation (PAF), and pregnancy. After the exclusion of patients, 400 of cases were included in this study. The patients were divided into two groups: CONUT <2, group 1 included 262 patients; CONUT ≥2, group 2 included 138 patients. The presence of chronic AF and its relationship with CONUT were also evaluated. RESULTS: Group 2 (18, 12.3%) exhibited higher in-hospital mortality than group 1 (12, 4.7%), (p=0.006). In addition, group 2 had higher chronic AF rates. Chronic AF was an independent predictor of in-hospital mortality in group 2 (p= 0.026). CONCLUSION: AIS patients with CONUT score>2 may have a greater in-hospital mortality. Chronic AF may be used as one of the predictors of in-hospital mortality in AIS patients with higher CONUT. KEY WORDS: Malnutrition, Atrial fibrillation, Stroke.

High Triglyceride-Glucose Index is Associated With Poor Prognosis in Patients With Acute Coronary Syndrome in Long-Term Follow-Up.

The triglyceride-glucose (TyG) index is calculated from fasting triglycerides and fasting glucose levels and is an indicator of insulin resistance. The present study investigates whether the TyG index has a role in predicting clinical outcomes in cases of acute coronary syndrome (ACS). This retrospective study included 646 patients with ST-elevation myocardial infarction (STEMI) and 1048 patients with non-ST-elevation myocardial infarction (NSTEMI). The association between major adverse cardiac events (MACEs) that developed in-hospital and at 60 months of follow-up and TyG index values were compared. Patients were divided into 2 groups: TyG index values of ≥8.65 and <8.65. During the hospital stay and 60 months of follow-up, 303 MACEs occurred. In both the STEMI and NSTEMI groups, as the TyG index increased, an increase was observed in MACE rates. MACE rates were also found to be highest in the group with TyG index ≥8.65 (P < .001). TyG index, C-reactive protein, and age were independent predictors of MACEs in both the NSTEMI and STEMI groups. The present study found a significant association between higher TyG index values and increased risk of MACEs in ACS patients. The TyG index may prove useful to predict clinical outcomes in ACS patients.

Correlation between frontal QRS-T angle, Tp-e interval, and Tp-e/QT ratio to coronary artery severity assessed with SYNTAX score in stable coronary artery disease patients.

Background: It is known that a wide frontal QRS-T(f[QRS-T]) angle in the electrocardiography (ECG) is associated with poor cardiovascular outcomes. The Tp-e (the interval from the peak to the end of the T wave) interval and Tp-e/QTc ratio show the dispersion of repolarization, and increased levels lead to ventricular arrhythmogenesis in congenital channelopathies and coronary heart disease. In this study, we aimed to investigate the relationship between f(QRS-T), Tp-e interval, and Tp-e/QTc ratio and SYNTAX score in stable coronary artery disease (SCAD) patients. Methods: A total of 403 patients who performed coronary angiography for SCAD were included. The study population was divided into two groups based on the SYNTAX score. Group 1 included 248 patients (high SYNTAX score > 0), and group 2 included 155 patients (low SYNTAX score = 0). SYNTAX score was calculated using an online SYNTAX score calculator from the coronary angiography images of each patient. The f(QRS-T) angle (QRS angle minus T angle) was calculated from the automated reports of the 12-lead ECG device. Tp-e interval and Tp-e/QTc ratio and other electrocardiographic parameters were recorded. Results: The mean SYNTAX score in group 1 was 8. F(QRS-T) angle, Tp-e duration, Tp-e/QT, and Tp-e/QTc were significantly higher in group 1 compared with group 2. In the multivariate regression analysis, F(QRS-T) angle and Tp-e duration were independent predictors for SYNTAX scores in SCAD patients. Conclusions: Our study showed that Tp-e interval, Tp-e/QTc ratio, and f(QRS-T) angle were increased in patients with higher SYNTAX scores in patients with SCAD patients.

Management of LDL-cholesterol levels in patients with Diabetes Mellitus in Cardiology Practice: Real-life evidence of Under-treatment from the EPHESUS registry.

BACKGROUND AND AIMS: Effective treatment of high low-density lipoprotein cholesterol (LDL-C) levels has been shown to improve cardiovascular outcomes of patients with diabetes mellitus (DM). Herein, we aimed to provide insight to the real-life management of patients with DM in terms of LDL-C goal attainment and adherence to lipid management recommendations. Our objective was also to reveal the reasons of poor LDL-C goal attainment by assessing the perceptions of both physicians and patients. METHODS: We compared the diabetic and non-diabetic patients from the database of a nationwide registry conducted in cardiology outpatient clinics with regard to the demographic characteristics, educational status, comorbidities, medications, laboratory parameters and LDL-C goal attainment. Also, both the patients and attending physicians were surveyed to analyse perceptions and awareness of hypercholesterolemia. RESULTS: Of the 1868 consecutively enrolled patients, 873 (47%) had DM. Proportion of patients on statins was significantly lower in patients with DM (67.8% vs 55.3%; P < .001). The proportion of patients who attained LDL-C targets were lower among the diabetic patients (17.8% vs 15%; P = .06). The most common causes of the discontinuation of statin therapy were negative media coverage about statins (32.1%), and recommendations of physicians to stop the lipid lowering therapy (29.6%). Analysis of the physician survey revealed that the physicians could determine the off-target patients accurately (negative predictive value 98.4%) while the positive predictive value (48.8%) was low. The reasons for not attaining the LDL-C goals in diabetic patients were not prescription of statins (38%) and inadequate (eg low-dose, non-adherent) statin (28.3%) dosages. CONCLUSIONS: In real-life clinical cardiology practice, diabetic patients are far below the recommended LDL-C treatment goals. High-intensity statin treatment in diabetic population is still avoided because of the concerns about polypharmacy and drug interactions. Also, the inertia of physicians and even cardiologists is probably a major cause of refraining of prescription of optimal statin dosages.

An Analysis of Myocardial Efficiency in Patients with Severe Asymptomatic Mitral Regurgitation.

BACKGROUND: It is difficult to determine left ventricular systolic performance in patients with severe mitral regurgitation (MR) since left ventricular ejection fraction (EF) could be preserved until the end stages of the disease. Myocardial efficiency (MEf) describes the amount of external work (EW) done by the left ventricle per unit of oxygen consumed (mVO2). In the present study, we aimed to investigate MEf in patients with asymptomatic severe MR using a novel echocardiographic method. METHODS: A total of 27 patients with severe asymptomatic MR and 26 healthy volunteers were included in this cross-sectional study. EW was measured using stroke volume and blood pressure, while mVO2 was estimated using double product and left ventricular mass. RESULTS: There were no differences between the groups with regards to EF (66% ± 5% vs. 69% ± 7%), while MEf was significantly reduced in patients with severe MR (25% ± 11% vs. 44% ± 12%, p < 0.001). This difference was maintained even after adjustment for age, gender and body surface area (adjusted x̅: 0.44, 95% CI: 0.39-0.49 for controls and adjusted x̅: 0.24, 95% CI: 0.19-0.29 for patients with severe MR). Further analysis showed that this reduction was due to an increase in total mVO2 in the severe MR group. MEf of thepatients who were both on ß-blockers and angiotensin converting enzyme inhibitors/angiotensin receptor blockers were higher than those who were not on any drugs, but this difference was not statistically significant (32% ± 15% vs. 23% ± 9%, p = 0.41). CONCLUSIONS: MEf was significantly lower in patients with asymptomatic severe MR and preserved EF.

The reasons of poor lipid target attainment for secondary prevention in real life practice: Results from EPHESUS.

OBJECTIVE: There are lack of studies considering the suboptimal management of dyslipidemia especially in cardiology outpatient clinics. This study was conducted to assess the patient adherence to cholesterol treatment recommendations and attainment of low-density-lipoprotein cholesterol (LDL-C) goals. METHODS: EPHESUS (NCT02608645) is a national, observational and multicenter registry which has been designed as a cross-sectional study to allow inclusion of all consecutive patients with hypercholesterolemia in cardiology outpatient clinics. The present subgroup analyses of the EPHESUS trial included patients with known peripheral artery disease or atherosclerotic cerebrovascular disease, and coronary heart disease namely secondary prevention. RESULTS: The present analysis of the EPHESUS study included 1482 patients (62.79 ± 10.4 years, 38.2% female) with secondary prevention from 40 sites in Turkey. Regarding recommended lipid targets for LDL-C, only 267 patients (18%) were below the target of 70 mg/dL. Females were significantly more off-target when compared with male patients (396, 85.5% vs 67, 14.5%; P = 0.017). Moreover, the achievement of LDL-C goal was significantly decreased with illiteracy (233, 19.2% vs 35, 13.1%; P = 0.02). Patients who think that the cholesterol treatment should be terminated when the cholesterol level of a patient has normalised were higher in the off-target group (34.0% vs 24.7%, P < 0.001). Besides, physician perceptions about LDL-C goal for secondary prevention were significantly related with LDL-C target attainment. CONCLUSIONS: EPHESUS is an important study with large population in terms of representing real-life practice of the adherence to dyslipidemia guidelines in secondary prevention patients in Turkey. Perceptions, knowledge, and compliance with the guidelines for secondary prevention have increased, but it is far below from the desired levels even in cardiology outpatient clinics. There is a need for patients' and physicians' education regarding the treatment of hyperlipidemia.

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.

Increased levels of red cell distribution width is correlated with presence of left atrial stasis in patients with non-valvular atrial fibrillation.

OBJECTIVE: Red cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) have been found to be associated with non-valvular atrial fibrillation (AF) and cardiovascular diseases. However, correlation of these parameters with presence of left atrial (LA) thrombus and/or spontaneous echo contrast (SEC) in patients with non-valvular AF has not been clarified. This study was an investigation of correlation of RDW, NLR, and clinical risk factors with LA thrombus and dense SEC in patients with non-valvular AF in the Turkish population. METHODS: The demographic, laboratory, and echocardiographic properties of 619 non-valvular AF patients who underwent transesophageal echocardiography (TEE) examination before direct current cardioversion (DCCV) or AF ablation treatment were retrospectively investigated. Complete blood count (CBC) and biochemical parameters were studied 6 to 12 hours before TEE examination. Left atrial stasis (LAS) markers were noted as presence of left atrial/left atrial appendage (LA/LAA) thrombus or dense spontaneous echo contrast (DSEC). RESULTS: Total of 325 (52%) patients with LAS were compared with 294 patients (48%) without LAS. In the LAS group, there were 274 (84%) patients with LA/LAA thrombus and 51 (16%) patients with DSEC. LAS (+) group, values for RDW (14.85±1.48 vs. 13.77±1.30; p<0.01), NLR (2.38 [1.58], vs. 2.10 [1.35]; p<0.01) and C-reactive protein (0.95 [0.61] vs. 0.88 [0.60] mg/L; p<0.01) were significantly higher than seen in LAS (-) group. In multivariate regression analysis, increased level of RDW, age, male gender, heart failure, duration of AF >6 months, and international normalized ratio <2 were independently correlated with presence of LAS. CONCLUSION: Our study indicated that increased level of RDW is independently correlated with higher risk for development of LAS in patients with non-valvular AF.

Guideline-adherent therapy for stroke prevention in atrial fibrillation in different health care settings: Results from RAMSES study.

OBJECTIVE: No studies have been conducted in Turkey to compare the quality of stroke prevention therapies provided in different healthcare settings in patients with atrial fibrillation (AF). Therefore, we aimed to evaluate possible differences between secondary (SH) and tertiary hospital (TH) settings in the effectiveness of implementing AF treatment strategies. METHODS: Baseline characteristics of 6273 patients with non-valvular AF enrolled in the RAMSES (ReAl-life Multicentre Survey Evaluating Stroke Prevention Strategies in Turkey) study were compared. RESULTS: Of the study population, 3312 (52.8%) patients were treated in THs and 2961 (47.2%) patients were treated in SHs. Patients treated in the SH setting were older (70.8±9.8 vs. 68.7±11.4years, p<0.001), had a lower socioeconomic status, had a higher CHA2DS2VASc and HASBLED scores (3.4±1.4 vs. 3.1±1.7, p<0.001 and 1.7±1.0 vs. 1.6±1.1, p<0.001 respectively), and had more comorbidities than patients treated in THs. Inappropriate oral anticoagulant use was more prevalent in SHs than THs (31.4% vs. 25.6%, p<0.001). When over- and undertreatment rates were compared among hospital types, overtreatment was more prevalent in THs (7.6% vs. 0.9%, p<0.001) while undertreatment was more common in SHs (30.5% vs. 17.9%, p<0.001). CONCLUSION: This study demonstrates the marked disparity between patient groups with AF presenting at SHs and THs. The use of guideline-recommended therapy is not adequate in either type of centre, overtreatment was more prevalent in THs and undertreatment was more prevalent in SHs.

Association of contrast-induced nephropathy with bare metal stent restenosis in STEMI patients treated with primary PCI.

BACKGROUND: Contrast induced nephropathy (CIN) has been proven as a clinical condition related to adverse cardiovascular outcomes. However, relationship between CIN and stent restenosis (SR) remains unclear. In this study, we aimed to investigate the association of CIN with SR rates after primary percutaneous coronary intervention (PCI) and bare metal stent (BMS) implantation. METHODS: A total number of 3225 patients who had undergone primary PCI for STEMI were retrospectively recruited. The medical reports of subjects were searched to find whether the patients had a control coronary angiogram (CAG) and 587 patients with control CAG were included in the study. The laboratory parameters of 587 patients were recorded and patients who developed CIN after primary PCI were defined. Contrast induced nephropathy was defined as either a 25% increase in serum creatinine from baseline or 0.5 mg/dL increase in absolute value, within 72 h of intravenous contrast administration. RESULTS: The duration between primary PCI and control CAG was median 12 months [8-24 months]. The rate of SR was significantly higher in CIN (+) group compared to CIN (-) group (64% vs. 46%, p < 0.01). In multivariate Cox regression analysis, male gender, stent length, admission WBC levels and presence of CIN (HR 1.39, 95% CI 1.06-1.82, p < 0.01) remained as the independent predictors of SR in the study population. CONCLUSION: Gender, stent length, higher serum WBC levels and presence of CIN are independently correlated with SR in STEMI patients treated with BMS implantation.

Comparison of long-term prognostic value of baseline SYNTAX and clinical SYNTAX scores in ST-segment elevation myocardial infarction patients with multivessel disease.

BACKGROUND: The prognostic value of baseline SYNTAX (SS) and clinical SYNTAX (cSS) scores has been shown in different populations with coronary artery disease. However, their prognostic value has not been compared in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease. METHODS: Patients who had undergone a primary percutaneous coronary intervention (PCI) for STEMI and had at least one critical lesion other than the culprit artery were recruited retrospectively. SS and cSS were calculated from medical records and angiograms and were compared in coronary artery by-pass grafting (CABG) and PCI groups. Long-term major adverse cardiac events (MACE) were defined as mortality, reinfarction, and target vessel revascularization. RESULTS: A total of 460 patients (214 in the CABG group and 246 in the PCI group) were analyzed. The baseline SS and the cSS were significantly higher in the CABG group compared with the PCI group (30.1±6.7 vs. 22.5±5.6; P<0.01 and 41.4±21.2 vs. 27.2±15.9; P<0.01, respectively). During a follow-up period of 32±8 months, 15 patients from the CABG group and 12 patients from the PCI group died (P=0.33), but the rate of MACE was higher in the PCI group (31 vs. 20%, P<0.01). Receiver operating curve analysis and univariate Cox regression analysis indicated that SS and cSS have prognostic value in the CABG group, but not in the PCI group. In the CABG group, SS and cSS showed significant discriminative power for long-term mortality (for SS>33 sensitivity 73.3%, specificity 71.4% and for cSS>38.4 sensitivity 93.3%, specificity 58.3%) and for MACE (for SS>34.5 sensitivity 50%, specificity 81.4% and for cSS>43.5 sensitivity 66.7%, specificity 73.8%). CONCLUSION: SS and cSS scores have prognostic value in STEMI patients with multivessel disease treated with CABG surgery. cSS may be superior to SS for prediction of long-term adverse events in CABG patients.

[Turkish Adult Risk Factor survey 2014: Overall mortality and coronary disease incidence in Turkey's geographic regions]. / TEKHARF 2014 taramasi ve Türkiye'de cografi bölgelere göre ölüm orani ile koroner hastalik insidansi.

OBJECTIVE: This study aimed to examine the overall and coronary mortality in the 2014 Turkish Adult Risk Factor Study survey, and the distribution of cumulative mortality and incident coronary heart disease (CHD) across 7 geographic regions. METHODS: Information on mode of death was appropriately obtained. Information collected from survivors was based on history, examination of the cardiovascular system and the Minnesota coding of electrocardiograms. Cox regression analyses were performed. RESULTS: Of the 1.323 participants to be surveyed, 87 were lost to follow-up, 753 examined, and 35 ascertained as deceased. In 448 subjects, verbal information alone was obtained regarding health status. Nineteen deaths were of coronary and cerebrovascular origin. Cumulative 24-year assessment of the entire cohort in the age bracket 45-74 years disclosed high coronary mortality, at 7.3 per 1000 person-years in men and 3.8 in women, and recorded a limited decline of 18% since the year 2000. Age-adjusted Cox regression analysis, comprising 614 deaths and 482 incident CHD over a follow-up of 9.6 years, revealed higher mortality rates in the Mediterranean region and in men in the Black Sea and Marmara regions. The age-adjusted CHD incidence was significantly higher in males of the Mediterranean and females of the Southeast regions. An estimated 400-420.000 incident CHD cases develop currently each year in Turkey. CONCLUSION: The generally high age-adjusted overall mortality in Turkey displays significant differences across geographic regions. Age-adjusted CHD incidence is not regressing sufficiently, and is especially high among men of the Mediterranean and women of the Southeast regions.

Presence of sigma shaped right coronary artery is an indicator of poor prognosis in patients with inferior myocardial infarction treated with primary percutaneous coronary intervention.

BACKGROUND: The effectiveness of primary percutaneous coronary intervention (PCI) in ST segment elevation myocardial infarction (STEMI) is well established. The clinical variables associated with poor prognosis in patients with STEMI have been extensively investigated. Right coronary artery (RCA) has two anatomical variations detected on coronary angiography namely C-shaped and sigma shaped RCA. The clinical importance of the shape of RCA in patients with STEMI has not been investigated before. PURPOSE: To investigate the prognostic value of RCA shape in patients with inferior STEMI treated with primary PCI. METHODS: Angiographic data of patients with inferior STEMI who were treated with primary PCI were retrospectively recruited. The differentiation of sigma and C-shaped RCAs was shown using single-frame angiograms, obtained during end-diastole of cardiac cycle in the left anterior oblique projection at 25° to 35° with no cranio-caudal angulation. Cardiovascular events at 30-days and on follow up were obtained through review of hospital records and telephone contact with the patient or the patient's relatives. Patients with C-shaped RCAs served as the control group. RESULTS: A total number of 824 patients with inferior STEMI who were treated with primary PCI for RCA were included. Sigma shaped RCA was observed in 15.1% of the subjects. In the sigma shaped RCA group, the door-to-balloon times were longer (32.5 ± 5.1 vs. 27.8 ± 4.6 min; P = 0.01) and TIMI 3 flow restoration rates were lower (76.8% vs. 94.1%; p=0.01) compared to the controls. Mean SYNTAX scores were significantly higher in patients with sigma shaped RCA. Four patients (3.2%) in the sigma shaped RCA group and 23 patients (3.3%) in the control group died by day 30. The incidence of stent thrombosis, recurrent MI, and target lesion revascularization, were similar between the groups. During the follow-up (mean 37.6 ± 13.4 months) 15 patients (12.3%) from the sigma shaped RCA group and 28 (4.1%) patients from the control group died (P = 0.01). The incidence of recurrent MI (27.2% vs. 13.7%; P = 0.01) and major adverse cardiovascular events (29.7% vs. 16.3%; P = 0.01) were significantly higher in the sigma shaped RCA group. In multivariate analysis, age, Killip class of >1, the presence of sigma shaped RCA, post PCI TIMI flow <3 and decreased left ventricular ejection fraction were the independent predictors of long term mortality. CONCLUSION: Presence of sigma shaped RCA is associated with more severe form of coronary artery disease and worse clinical outcome in patients with inferior STEMI.

Coexisting bicuspid aortic and pulmonary valves with normally related great vessels diagnosed by live/real time three-dimensional transesophageal echocardiography.

Coexistence of bicuspid aortic and pulmonary valves in the same patient is a very rare entity identified mainly during surgery and postmortem. To the best of our knowledge, only one case has been diagnosed by two-dimensional echocardiography in a newborn with malposition of the great arteries but no images were presented. Here, we are reporting the first case of bicuspid pulmonary and aortic valves diagnosed by live/real time three-dimensional transesophageal echocardiography in an adult with normally related great arteries.

Prognostic value of serum resistin levels in patients with acute myocardial infarction.

BACKGROUND: Resistin is a novel adipokine that is suggested to be involved in inflammatory conditions and atherosclerosis. AIM: To investigate the prognostic importance of resistin in acute myocardial infarction (AMI) patients. METHODS: Resistin levels were measured in a population of 132 patients with AMI, of whom 72 (54%) had a diagnosis of ST elevation myocardial infarction (STEMI), and 60 (46%) had non-ST elevation myocardial infarction (NSTEMI). Thirty-three consecutive subjects who were referred to elective coronary angiography due to chest pain evaluation with normal coronary angiograms served as controls. All patients were followed-up for the occurrence of major adverse cardiac events (MACE). RESULTS: There was a significant increase in serum resistin levels in patients with AMI compared to controls (3.71 ± 4.20 vs. 2.00 ± 1.05, p = 0.001, respectively). However, serum resistin levels were similar in patients with STEMI and NSTEMI. (4.26 ± 5.11 vs. 3.06 ± 2.64, p = 0.49, respectively). The patients with MACE had significantly higher levels of serum resistin levels compared to either the AMI or the control group (6.35 ± 5.47, p = 0.005, respectively). Logistic regression analysis revealed that resistin, left ventricular ejection fraction, and coronary artery bypass graft were independent predictors of MACE in AMI patients (OR = 1.11, 95% CI 1.01-1.22, p = 0.03 and OR = 3.84, 95% CI 1.26-11.71, p = 0.018, respectively). CONCLUSIONS: Serum resistin level was increased in patients with AMI and constituted a risk factor for MACE in this group.
