Background: The currently used scheme for the classification of infarct location and extent in anterior myocardial infarction (MI) is intuitive rather than being evidence-based, and recent evidence suggests that it may be misleading both in anatomic and prognostic sense. Material and Methods: Consecutive patients with the diagnosis of anterior MI were enrolled. All electrocardiograms (ECG) were first classified according to established scheme and then reassessed using newer criteria for angiographic site of occlusion. The site of left anterior descending (LAD) occlusion was determined using multiple angiographic views. Clinic, echocardiographic and angiographic outcomes were compared. Results: A total of 379 anterior MI cases were enrolled, final study population consisted of 267 patients. The established scheme did not predict infarct size or adverse outcomes. Location of the myocardium subtended by the occluded coronary network did not match with the anatomic location as ECG classification implies. Many high-risk patients with proximal LAD were classified as “anteroseptal”, whereas the majority of the patients labeled as “extensive anterior MI” had in fact distal occlusions. On the other hand, expert interpretation was fairly accurate in predicting adverse outcomes and the site of angiographic involvement. Conclusion: Classifying patients according to the established scheme neither gives prognostic information nor accurately localizes infarction. It should be regarded as obsolete and its use should be abandoned. Instead, the extent of infarction can be inferred from newer criteria provided by the angiographic correlation studies. © 2019 Wiley Periodicals, Inc.

- Abstract
In December 2019, in the city of Wuhan, in the Hubei province of China, treatment-resistant cases of pneumonia emerged and spread rapidly for reasons unknown. A new strain of coronavirus (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) was identified and caused the first pandemic of the 21st century. The virus was officially detected in our country on March 11, 2020, and the number of cases increased rapidly; the virus was isolated in 670 patients within 10 days. The rapid increase in the number of patients has required our physicians to learn to protect both the public and themselves when treating patients with this highly infectious disease. The group most affected by the outbreak and with the highest mortality rate is elderly patients with known cardiovascular disease. Therefore, it is necessary for cardiology specialists to take an active role in combating the epidemic. The aim of this article is to make a brief assessment of current information regarding the management of cardiovascular patients affected by COVID-19 and to provide practical suggestions to cardiology specialists about problems and questions they have frequently encountered. / Aralık 2019’da, Çin’in Hubei eyaletindeki Wuhan şehrinde, nedeni bilinmeyen, tedaviye dirençli pnömoni olguları ile ortaya çıkan ve devamında hızla yayılarak XXI. yüzyılın ilk pandemisine neden olan yeni koronavirüsün (severe acute respiratory syndrome koranavirüs-2 [SARS-CoV-2]) 11 Mart 2020 tarihinde ülkemizde de resmi olarak saptanmasının ardından olgu sayısı hızla artmış ve 10 gün içerisinde 670 hastada virüs izole edilmiştir. Hasta sayısındaki hızlı artış, hekimlerimizin bir yandan etkilenen hastalara müdahale ederken diğer yandan toplumu ve kendilerini korumayı öğrenmelerini gerektirmektedir.

Background: In a minority of the patients presenting with ST-segment elevation (STE) myocardial infarction (MI), electrocardiogram (ECG) may show a balanced STE in both anterior and inferior lead groups and may cause diagnostic confusion about involved myocardial territory. In this study, we sought ECG clues which may facilitate discriminating (1) MI location and then (2) culprit artery in patients with difficult-to-discern ECGs. Material and methods: Consecutive patients with the diagnosis of STEMI were scanned and patients with ECGs displaying both anterior and inferior STE were enrolled. ECGs with obvious ST elevation in either lead group and reciprocal ST-segment depression were excluded. Predictive power of several ECG variables has been analyzed and an algorithm has been constructed. Results: A total of 959 STEMI cases were scanned, the final study population was consisted of 114 patients. Our algorithm for locating MI territory had a sensitivity, specificity, positive and negative predictive value of 72.1%, 92.5%, 91.7% and 74.2% for inferior versus anterior location, respectively (P < 0.001, ? = 0.652). As anterior MI was strictly reserved for left anterior descending (LAD) artery occlusion, these diagnostic values were also valid for discriminating circumflex artery [Cx]/right coronary artery [RCA] versus LAD as the culprit artery. In patients classified as having inferior MI, an STE in lead III greater than STE in lead II favored RCA over Cx as the culprit artery with a sensitivity, specificity, positive and negative predictive value of 97%, 46.6%, 80% and 87.5%, respectively (P < 0.001; ? = 0.544). Conclusion: Our algorithm can be used in difficult-to-discern ECGs for defining involved myocardial territory and culprit artery. © 2018 Elsevier Inc.

Abstract Background Symptoms in hypertrophic cardiomyopathy (HC) appear to be caused by diastolic dysfunction, myocardial ischemia, left ventricle (LV) outflow obstruction, and atrial fibrillation. However, clinical deterioration and severe heart failure symptoms can be observed in patients without any of these factors. Thus, the aim of this study is to determine the echocardiographic predictors of severe heart failure symptoms in patients with HC. Methods and results 86 HC patients were compared according to symptomatic status. Patients with severe heart failure symptoms were older, preponderantly female, had more often LV outflow obstruction and mitral regurgitation, longer E wave deceleration time (EDt), higher E/Ea ratios and lower LV tissue Doppler (TD) velocities when compared to rest of the patients. LV outflow obstruction (r = 0.43, R2 = 0.19, p < 0.0001), LV lateral mitral annular systolic TD velocity (LMSa) (r = 0.51, R2 = 0.26, p < 0.006) and EDt (r = 0.55, R2 = 0.30, p < 0.027) were found to be the independent predictors for severe heart failure symptoms in forward stepwise regression. Conclusion In HCM patients with sinus rhythm and normal LV systolic function, LMSa, EDt and LV outflow obstruction are independent predictors of heart failure symptoms. Diastolic dysfunction determined with EDt, occult systolic dysfunction which is detected with TD analysis, and afterload increase as result of LV outflow obstruction seem to be the main echocardiographic factors affecting symptomatic status in HCM patients with sinus rhythm and normal systolic function.

İM midenin premalign lezyonlarından biridir. İM saptanan hastaların takibinde nasıl bir yöntem izlenmesi gerektiği yeterince açık değildir. Kılavuzlar mide kanseri insidansı nispeten düşük olan ülkelerde yalnızca mide kanseri riski olan hastaların takibini önermektedir. Bununla birlikte takipte nasıl bir yol izleneceği kesin olarak belirlenmediğinden hekimin kişisel kararına kalmış görünmektedir. Son yıllarda gelişen magnifiye endoskopi veya NBI gibi yöntemler kromoendoskopi ile birlikte kulanıldığında hastaların tanısında belirgin bir iyileşme sağlamaktadır. Ancak bu yöntemler günümüzde oldukça pahalı ve özel ekipmanlar gerektirmektedir.Yaklaşık 40 yıldır güvenle kullanılmakta olan kromoendoskopinin birçok gastrointestinal lezyonun tanınmasında konvansiyonel endoskopiye olan üstünlüğü bilinmektedir. Birçok çalışmada gösterildiği gibi metilen mavisi kullanılarak yapılan kromoendoskopi İM saptamada etkili bir yöntemdir. Metilen mavisi ucuz, kolay erişilebilen ve uygulanması kolay olan absorbtif bir boyadır.Literatürde özellikle hastaların takibinde kromoendoskopinin etkinliğini araştıran çalışma sayısı kısıtlıdır. Bu çalışmada uygulanması kolay ve ucuz olan kromoendoskopinin İM'nin takibinde konvansiyonel endoskopiye oranla ek bir katkı sağlayıp sağlayamayacağı araştırıldı.Ocak 2010-Eylül 2011 tarihleri arasında Ufuk Üniversitesi Tıp Fakültesi Gastroenteroloji polikliniğine başvuran ve son 6 ay içinde yapılan İM saptanmış olan 26 erişkin hasta çalışmaya dahil edildi. Her hastaya konvansiyonel endoskopi yapıldı ve Sydney proyokolüne uygun olarak rastlantısal biyosiler alındı. Daha sonra aynı seansta metilen mavisi kullanılarak kromoendoskopi yapıldı. Boya tuttuğu izlenen alanlardan biyopsi alındı. Hastaların biyopsi sonuçları değerlendirildi.Sonuç olarak kromoendoskopi, İM tespitinde konvansiyonel endoskopiye oranla daha başarılı bulundu (%69,2 vs %23). Özellikle korpustaki İM'lerin tespitinde belirgin derecede üstün idi (%44,8 vs %11,7). Endoskopisitin görsel değerlendirmesi kromoendoskopiye oranla daha başarısız idi (%50 vs %69,2).İM olduğu bilinen hastaların takibinde konvansiyonel endoskopi ile kromoendoskopinin etkinliğinin karşılaştırıldığı bu çalışmada kromoendoskopinin konvansiyonel endoskopiye belirgin üstünlüğü olduğu gösterilmiştir. Özellikle mide kanseri riski taşıyan ve İM tespit edilen hastaların takibinde NBI veya magnifiye endoskopi gibi daha etkin olduğu bilinen bir yöntem kullanma imkanı yoksa konvansiyonel endoskopi yerine güvenilir, ucuz ve etkili bir yöntem olan kromoendoskopinin kullanılması rasyonel bir seçim olacaktır. IM (intestinal metaplasia ) is a gastric premalignant lesion. How screening of patients with IM is unclear. In populations with a low gastric cancer burden, the decision to recommend a screening program should be made on an individual patient basis. Periodic upper endoscopy (possibly with specialized techniques such as chromoendoscopy, NBI or magnification endoscopy) can be offered to patients who are considered to be at increased risk, although the benefits and risks of such an approach are unclear.Chromoendoscopy is an endoscopic technique that uses stains during endoscopy to highlight differences in mucosa, as well as dysplastic and malignant changes that are not apparent in conventional endoscopy. Methylene blue staining is used to identify metaplastic absorptive epithelium, such as IM in the stomach.The aim of this study was to compare the accuracy and sensitivity of chromoendoscopy with conventional endoscopy and systematic biopsies for locating IM of the gastric mucosa.During a period of between January 2011 and September 2011, in the Department of Gastroenterology at the Ufuk University Medical School, 26 patients in whom previous routine endoscopic biopsies showed intestinal metaplasia were enrolled in a prospective study. Each patient underwent a two-step endoscopy procedure: conventional endoscopy and chromoendoscopy. Biopsies were taken during each step and were studied by an expert pathologist.The present study demonstrated that chromoendoscopy is superior to conventional endoscopy for the detection of IM (69,2% vs 23%). Chromoendoscopy was significantly more effective in demonstrating the involvement of body (44,8% vs 11,7%).Based on the results of the present study, chromoendoscopy using methylene blue is an effective method for the detection and accurate delineation of IM of the stomach. Chromoendoscopy can be recommended when a follow-up endoscopy unless specialized techniques such as NBI or magnification endoscopy. 61

- Abstract
Objectives: This study has been conducted to investigate the non-invasive diagnostic journey of patients with a transthyretin amyloid cardiomyopathy (aTTR-CM) in Turkey, identify the challenges and uncertainties encountered on the path to diagnosis from the perspectives of expert physicians, and develop recommendations that can be applied in such cases., Methods: This study employed a three-round modified Delphi method and included 10 cardiologists and five nuclear medicine specialists. Two hematologists also shared their expert opinions on the survey results related to hematological tests during a final face-to-face discussion. A consensus was reached when 80% or more of the panel members marked the "agree/strongly agree" or "disagree/strongly disagree" option., Results: The panelists unanimously agreed that the aTTR-CM diagnosis could be established through scintigraphy (using either 99mTc-PYP, 99mTc-DPD, or 99mTc-HMPD) in a patient with suspected cardiac amyloidosis (CA) without a further investigation if AL amyloidosis is ruled out (by sFLC, SPIE and UPIE). In addition, scintigraphy imaging performed by SPECT or SPECT-CT should reveal a myocardial uptake of Grade ≥2 with a heart-to-contralateral (H/CL) ratio of ≥1.5. The cardiology panelists recommended using cardiovascular magnetic resonance (CMR) and a detailed echocardiographic scoring as a last resort before considering an endomyocardial biopsy in patients with suspected CA whose scintigraphy results were discordant/inconclusive or negative but still carried a high clinical suspicion of aTTR-CM., Conclusion: The diagnostic approach for aTTR-CM should be customized based on the availability of diagnostic tools/methods in each expert clinic to achieve a timely and definitive diagnosis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Çavuşoğlu, Başarıcı, Tüfekçioğlu, Özpelit, Özdemir, Sivrikoz, Altay, Değertekin, Dinçer, İkitimur, Kahveci, Bozkurt, Erkılıç, Kaya, Beksaç, Salihoğlu and Tokgözoğlu.)

- Abstract
Objective: The aim of this study was to determine adiponectin and copeptin levels that might be prognostic for cardiovascular mortality (CvsM) in ST-segment elevation myocardial infarction (STEMI) patients who had percutaneous coronary intervention (PCI)., Methods: Patients who underwent PCI between November 2010 and April 2011 were enrolled and followed for more than eight years. The baseline, demographic and angiographic findings, in-hospital follow up, laboratory results including adiponectin and copeptin levels, and echocardiographic data of the patients were evaluated., Results: There were 78 males and 20 females. The CvsM rate was 26.66% at 112 months of follow up. Some factors were significantly related to CvsM and adiponectin level was an independent predictor of mortality. A cut-off value of ≥ 8 950 ng/ml for adiponectin and ≥ 7.41 ng/ml for copeptin was related to a 3.01- and 2.83-times higher CvsM risk, respectively., Conclusion: Adiponectin level was a predictor for CvsM. Higher levels of adiponectin and copeptin could predict a higher risk of CvsM in STEMI patients.

- Abstract
Objective: The current understanding of heart failure (HF) largely centers round left ventricular (LV) function; however, disorders in serial integration of cardiovascular system may cause a hemodynamic picture similar to left-sided HF. Therefore, focusing only on LV function may be a limited and misleading approach. We hypothesized that cardiovascular system has four major integration points, and disintegration in any of these points may produce the hemodynamic picture of HF., Methods: We used a computational model in which mechanical properties of each chamber were characterized using time-varying elastance, and vascular beds were modeled by series of capacitances and resistances. The required percent changes in stressed volume (Vstressed) was presented as a measure of congestion susceptibility., Results: As mean systemic pressure is closely correlated with pulmonary capillary wedge pressure (PCWP), arteriovenous disintegration can create a diastolic dysfunction pattern, even without any change in diastolic function. For 10%, 20%, 30%, 40%, and 50% interventricular disintegration, required Vstressed for reaching a PCWP over 20 mmHg was decreased by 42.0%, 31.2%, 22.5%, 15%, and 8.3%, respectively. Systolodiastolic disintegration, namely combined changes in the end-diastolic and systolic pressure-volume curves and ventriculoarterial disintegration significantly decreases the required percent change in Vstressed for generating congestion., Conclusion: Four disintegration points can produce the hemodynamic picture of HF, which indicates that combination of even seemingly mild abnormalities is more important than an isolated abnormality in a single function of a single chamber. Our findings suggest that a "cardiovascular disintegration" perspective may provide a different approach for assessing the HF syndrome.

Background: Although ST-segment elevation (STE) has been used synonymously with acute coronary occlusion (ACO), current STE criteria miss nearly one-third of ACO and result in a substantial amount of false catheterization laboratory activations. As many other electrocardiographic (ECG) findings can reliably indicate ACO, we sought whether a new ACO/non-ACO myocardial infarction (MI) paradigm would result in better identification of the patients who need acute reperfusion therapy., Methods: A total of 3000 patients were enrolled in STEMI, non-STEMI and control groups. All ECGs were reviewed by two cardiologists, blinded to any outcomes, for the current STEMI criteria and other subtle signs. A combined ACO endpoint was composed of peak troponin level, troponin rise within the first 24 h and angiographic appearance. The dead or alive status was checked from hospital records and from the electronic national database., Results: In non-STEMI group, 28.2% of the patients were re-classified by the ECG reviewers as having ACO. This subgroup had a higher frequency of ACO, myocardial damage, and both in-hospital and long-term mortality compared to non-STEMI group. A prospective ACOMI/non-ACOMI approach to the ECG had superior diagnostic accuracy compared to the STE/non-STEMI approach in the prediction of ACO and long-term mortality. In Cox-regression analysis early intervention in patients with non-ACO-predicting ECGs was associated with a higher long-term mortality., Conclusions: We believe that it is time for a new paradigm shift from the STEMI/non-STEMI to the ACOMI/non-ACOMI in the acute management of MI.

- Abstract
Objective: This was an investigation of the relationship between the N-terminal pro-brain natriuretic peptide (NT-proBNP) level and mortality in patients with stage 3-4 chronic kidney disease (CKD)., Methods: This study was designed as a subgroup analysis of the Heart Failure Prevalence and Predictors in Turkey (HAPPY) study. The HAPPY study included 4650 randomly selected individuals from the 7 geographical regions of Turkey. A total of 191 subjects from the original cohort with an estimated glomerular filtration rate (eGFR) <60 mL/min/1.1.73 m² were enrolled in this study and the relationship between NT-proBNP and mortality was investigated. Prognostic variables for total and cardiovascular mortality were also examined using Cox regression analysis., Results: The mean length of follow-up was 76.12±22.45 months. The mean NT-proBNP level was 423.54±955.88 pg/mL. During follow-up, 51 subjects (26.7%) died from any cause and 36 subjects (18.8%) died from a cardiovascular cause. The presence of hypertension (hazard ratio [HR]: 1.89; 95% confidence interval [CI]: 1.01-3.50; p=0.048), anemia (HR: 2.49; 95% CI: 1.20-5.15; p=0.014), male gender (HR: 2.64; 95% CI: 1.44-4.86; p=0.002) and log NT-proBNP (HR: 4.93; 95% CI: 2.83-8.58; p<0.001) were independent variables for total mortality. The presence of hypertension (HR: 2.47; 95% CI: 1.09-5.56; p=0.029), male gender (HR: 2.79; 95% CI: 1.38-5.62; p=0.004), eGFR (HR: 0.94; 95% CI: 0.91-0.98; p=0.005) and log NT-proBNP (HR: 6.31; 95% CI: 3.11-12.81; p<0.001) were independent predictors of cardiovascular mortality., Conclusion: NT-proBNP was found to be an independent prognostic marker in patients with stage 3-4 CKD.

- Abstract
Background: We identified a specific pattern that does not display contiguous ST-segment elevation (STE), indicating acute inferior myocardial infarction (MI) with concomitant critical stenoses on the other coronary arteries. We sought to define the frequency, underlying anatomic substrate, diagnostic power and prognostic implications of this pattern., Methods: One thousand patients with a diagnosis of non-STEMI were enrolled as the study group. Within the same date range, all patients with inferior STEMI and 1000 patients, who had been excluded for MI (no-MI), were also enrolled. The coronary angiograms were reviewed by two interventional cardiologists, who were blinded to the ECGs. Echocardiographic wall motion bullseye displays and coronary angiography maps were constructed for each group. The dead or alive status was checked from the electronic national database., Results: The final study population consisted 2362 patients. The prespecified ECG pattern was observed in 6.3% (61/966) of the non-STEMI cohort and 0.5% (5/1000) of no-MI patients. These patients had a larger infarct size as evidenced by 24-hour troponin levels, higher frequency of angiographic culprit lesion, and higher frequency of composite acute coronary occlusion endpoint compared to their non-STEMI counterparts. On the other hand, they had a similar in-hospital (5% vs. 4%, respectively; P = 0.675) and one-year mortality compared to the patients with inferior STEMI (11% vs. 8%, respectively; P = 0.311)., Conclusion: We here define a new ECG pattern indicating inferior MI in patients with concomitant critical lesion(s) in coronary arteries other than the infarct-related artery. Patients with this pattern have multivessel disease and higher mortality., Competing Interests: Declaration of competing interest The authors report no relationships that could be construed as a conflict of interest., (Copyright © 2020 Elsevier Inc.

In December 2019, in the city of Wuhan, in the Hubei province of China, treatment-resistant cases of pneumonia emerged and spread rapidly for reasons unknown. A new strain of coronavirus (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) was identified and caused the first pandemic of the 21st century. The virus was officially detected in our country on March 11, 2020, and the number of cases increased rapidly; the virus was isolated in 670 patients within 10 days. The rapid increase in the number of patients has required our physicians to learn to protect both the public and themselves when treating patients with this highly infectious disease. The group most affected by the outbreak and with the highest mortality rate is elderly patients with known cardiovascular disease. Therefore, it is necessary for cardiology specialists to take an active role in combating the epidemic. The aim of this article is to make a brief assessment of current information regarding the management of cardiovascular patients affected by COVID-19 and to provide practical suggestions to cardiology specialists about problems and questions they have frequently encountered.

- Abstract
Background: The currently used scheme for the classification of infarct location and extent in anterior myocardial infarction (MI) is intuitive rather than being evidence-based, and recent evidence suggests that it may be misleading both in anatomic and prognostic sense., Material and Methods: Consecutive patients with the diagnosis of anterior MI were enrolled. All electrocardiograms (ECG) were first classified according to established scheme and then reassessed using newer criteria for angiographic site of occlusion. The site of left anterior descending (LAD) occlusion was determined using multiple angiographic views. Clinic, echocardiographic and angiographic outcomes were compared., Results: A total of 379 anterior MI cases were enrolled, final study population consisted of 267 patients. The established scheme did not predict infarct size or adverse outcomes. Location of the myocardium subtended by the occluded coronary network did not match with the anatomic location as ECG classification implies. Many high-risk patients with proximal LAD were classified as "anteroseptal", whereas the majority of the patients labeled as "extensive anterior MI" had in fact distal occlusions. On the other hand, expert interpretation was fairly accurate in predicting adverse outcomes and the site of angiographic involvement., Conclusion: Classifying patients according to the established scheme neither gives prognostic information nor accurately localizes infarction. It should be regarded as obsolete and its use should be abandoned. Instead, the extent of infarction can be inferred from newer criteria provided by the angiographic correlation studies., (© 2019 Wiley Periodicals, Inc.)

- Abstract
diac structure and function in obese patients. This study was an examination of the short-term effects of sleeve gastrectomy on body measurements and diastolic function., Methods: A total of 41 consecutive obese patients who were scheduled to undergo a sleeve gastrectomy procedure were included in the study. Baseline body and echocardiographic measurements and the follow-up counterpart data, including total and excess weight loss percentages, were recorded., Results: The mean age of the patients was 42.85+-11.47 years. Of the total, 21 (51.1%) patients were female. The mean body mass index (BMI) was 44.86+-5.62 kg/m². The mean duration of follow-up was 91.24+-44.48 days. The participants demonstrated statistically significant weight loss (26.64+-10.95 kg), as well as a decrease in BMI (8.84+-3.93 kg/m²) and body surface area (0.27+-0.12 m²). A significant increase in E velocity and mitral annular e velocity were observed, as well as a significant decrease in A velocity, E/e ratio, left ventricle mass, and left atrial volume (LAV). No significant correlations between the body measurement changes and changes in echocardiographic parameters were observed, with the exception that the excessive weight loss percentage was moderately correlated with a change in LAV., Conclusion: Sleeve gastrectomy led to a significant decrease in body weight and improved diastolic function parameters in the short-term. No significant relationship was found between the amount of weight loss and change in echocardiographic measurements.

- Abstract
Background: In a minority of the patients presenting with ST-segment elevation (STE) myocardial infarction (MI), electrocardiogram (ECG) may show a balanced STE in both anterior and inferior lead groups and may cause diagnostic confusion about involved myocardial territory. In this study, we sought ECG clues which may facilitate discriminating (1) MI location and then (2) culprit artery in patients with difficult-to-discern ECGs., Material and Methods: Consecutive patients with the diagnosis of STEMI were scanned and patients with ECGs displaying both anterior and inferior STE were enrolled. ECGs with obvious ST elevation in either lead group and reciprocal ST-segment depression were excluded. Predictive power of several ECG variables has been analyzed and an algorithm has been constructed., Results: A total of 959 STEMI cases were scanned, the final study population was consisted of 114 patients. Our algorithm for locating MI territory had a sensitivity, specificity, positive and negative predictive value of 72.1%, 92.5%, 91.7% and 74.2% for inferior versus anterior location, respectively (P < 0.001, φ = 0.652). As anterior MI was strictly reserved for left anterior descending (LAD) artery occlusion, these diagnostic values were also valid for discriminating circumflex artery [Cx]/right coronary artery [RCA] versus LAD as the culprit artery. In patients classified as having inferior MI, an STE in lead III greater than STE in lead II favored RCA over Cx as the culprit artery with a sensitivity, specificity, positive and negative predictive value of 97%, 46.6%, 80% and 87.5%, respectively (P < 0.001; φ = 0.544)., Conclusion: Our algorithm can be used in difficult-to-discern ECGs for defining involved myocardial territory and culprit artery., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: It may sometimes be difficult to differentiate subtle ST-segment elevation (STE) due to anterior myocardial infarction (MI) from benign variant (BV) STE. Recently, two related formulas were proposed for this purpose. However, they have never been tested in an external population., Materials and Methods: Consecutive patients from May 2017 to January 2018, who were admitted with the diagnosis of acute anterior STEMI, were enrolled. Electrocardiograms were systematically reviewed and only subtle ones were included. First 200 consecutive patients with noncardiac chest pain were also enrolled as a control group. Relevant electrocardiographic parameters were measured., Results: A total of 379 anterior MI and 200 BV-STE cases were enrolled during study period. A total of 241 patients in STEMI group were excluded for not matching subtleness criteria, four patients in control group were also excluded because of prior left-anterior descending artery intervention. The three-variable formula, with recommended cut-point of 23.5, had a sensitivity, specificity, and diagnostic accuracy of 73.9%, 86.7%, and 81.4%, respectively. The four-variable formula, with the published cut-point of 18.2, had a sensitivity, specificity, and diagnostic accuracy of 83.3%, 87.7%, and 85.9%, respectively., Conclusion: Three- and four-variable formulas with recommended cutoffs have a reasonable sensitivity, specificity, and diagnostic accuracy in differentiating subtle STEMI with BV-STE. Although both perform well, the four-variable formula has a higher sensitivity, specificity, and diagnostic accuracy and should be preferred., (© 2018 Wiley Periodicals, Inc.)

- Abstract
Benign variant (BV) ST-segment elevation (STE) is present in anterior chest leads in most individuals and may cause diagnostic confusion in patients presenting with chest pain. Recently, 2 regression formulas were proposed for differentiation of BV-STE from anterior ST-elevation myocardial infarction (MI) on the electrocardiogram, computation of which is heavily device-dependent. We hypothesized that a simpler visual-assessment-based formula, namely (R-wave amplitude in lead V4 + QRS amplitude in V2) - (QT interval in millimeters + STE60 in V3), will be noninferior to these formulas. Consecutive cases of proven left anterior descending occlusion were reviewed, and those with obvious ST elevation MI were excluded. First 200 consecutive patients with noncardiac chest pain and BV-STE were also enrolled as a control group. Relevant electrocardiographic parameters were measured. There were 138 anterior MI and 196 BV-STE cases. Our simple formula was superior to the 3- and noninferior to the 4-variable formulas. This new practical formula had an excellent area-under curve of 0.963 (95% confidence interval, 0.946 to 0.980, p<0.001). It also had a sensitivity, specificity and diagnostic accuracy of 86.9%, 92.3%, and 90.1%, respectively. In conclusion, a simple visual assessment-based formula can reliably differentiate STE MI from BV-STE. Also, our results emphasize that focusing only on STE for diagnosing acute coronary occlusion is extremely insensitive and even puts the term "STEMI" itself into question., (Copyright © 2018.

- Abstract
Objective: The purpose of this study was to identify patient characteristics and statin discontinuation-related factors in patients with hypercholesterolemia., Methods: A total of 532 patients (age mean±SD: 57.4±11.5 years; 52.4% women, 47.6% men) with hypercholesterolemia and statin discontinuation were included in this national cross-sectional non-interventional observational study. Data on socio-demographic characteristics of patients, cardiovascular risk factors, past treatment with and discontinuation of statin treatment were collected in one visit., Results: Mean±SD duration of hypercholesterolemia was 4.9±4.2 years at time of discontinuation of statin treatment. Statin treatment was initiated by cardiologists in the majority of cases (55.8%), whereas discontinuation of statin treatment was decided by patients in the majority of cases (73.7%), with patients with higher (at least secondary education, 80.4%) more likely than those with lower (only primary education, 69.7%) to decide to discontinue treatment (p=0.022). Negative information about statin treatment disseminated by TV programs-mostly regarding coverage of hepatic (38.0%), renal (33.8%), and muscular (32.9%) side effects (32.9%)-was the most common reason for treatment discontinuation., Conclusion: The decision to discontinue statin treatment was made at the patient's discretion in 74% of cases, with higher likelihood of patients with higher educational status deciding to discontinue treatment and switch to non-drug lipid-lowering alternatives. Cardiologists were the physicians most frequently responsible for the initiation of the statin treatment; coverage of several non-life-threatening statin side effects by TV programs and patients' lack of information regarding high cholesterol and related risks were the leading factors predisposing to treatment discontinuation.

- Abstract
Objectives: The aim was to investigate the microbiological characteristics and complications of infective endocarditis (IE) in 119 patients treated in our center for IE, diagnosed by modified Duke criteria., Study Design: The archive records of 119 patients (82 [69%] males; 37 [31%] females; mean age 39 ± 16 years) with a definite diagnosis of IE between January 1997 and November 2004 were systematically reviewed for clinical and microbiological properties and complications., Results: The most common complaint of the patients was fever and malaise (102 patients, 85.7%, each). Culture was negative in 68 patients (57.1%), while Staphylococcus aureus was the most common etiological agent in culture positive cases. The aortic valve was the most common region of vegetation (43 patients, 36.1%). The frequency of surgical operation for valvular insufficiency due to IE was 75.6%, and the frequency of congestive heart failure was 53.8% (64 patients)., Conclusion: IE is still an important disease considering its high morbidity and mortality rates, increased life expectancy of the patients, and increased number of valve replacement procedures.

- Abstract
Left ventricular (LV) noncompaction is a congenital dysfunction of endomyocardial morphogenesis characterized by excessively prominent trabeculations and deep intratrabecular recesses of the myocardium. Its association with Ebstein's anomaly is very rare. A 13-year-old boy presented to the outpatient clinic for a cardiac evaluation before enrolling in a sports activity. On physical examination, there was a grade 1/6 systolic murmur at the tricuspid valve location. His electrocardiogram was normal. Transthoracic echocardiography revealed numerous large trabeculations and deep intratrabecular recesses at the apex, lateral wall, and the apical part of the interventricular septum. Color flow Doppler examination confirmed the presence of blood flow within the trabeculae. The size and ejection fraction of the LV was normal (65%). The attached margins of the septal and inferior leaflets of the tricuspid valve were apically displaced and there was mild tricuspid regurgitation. The distance between the mitral and tricuspid annuli was 20 mm. The right ventricle showed no dilatation and had normal systolic function, but the right atrium was moderately enlarged. As the patient was asymptomatic and the LV systolic function was preserved, he was scheduled for regular follow-up without medication except for low-dose aspirin (100 mg/day). After five years of follow-up, he was still asymptomatic with normal size and ejection fraction of both ventricles.

- Abstract
A 51-year-old woman presented with severe chest pain minutes after starting intravenous paclitaxel as a part of the systemic chemotherapy due to ovarian carcinoma. The electrocardiogram (ECG) revealed sinus rhythm with ST-segment elevations in inferior and anterior leads. The ST-segment elevations resolved immediately after sublingual nitroglycerine. Cardiac troponin T and CPK MB levels remained in the normal range at repeat measurements. It was presumed that in spite of standard premedication, paclitaxel had induced acute coronary syndrome with ST-segment elevations in this patient., (2009 Wiley Periodicals, Inc.)

- Abstract
The evaluation of left ventricular function and viability is critical in patients with suspected or documented ischemic heart disease. Recently, cardiac multislice computed tomography (MSCT) has emerged as a powerful modality for cardiac imaging. In addition to coronary artery assessment, contrast enhanced MSCT can provide reliable information about myocardial function, perfusion and viability. This review will focus on the pathophysiological mechanisms and clinical applications of contrast enhanced myocardial function and viability MSCT imaging.

- Abstract
Objectives: Traditional risk factors may underestimate the burden of subclinical atherosclerosis in women. Recently, multislice computed tomography (MSCT) has become widely available in detecting early coronary artery disease (CAD). We sought the prevalence of CAD in low to moderate-risk asymptomatic women by MSCT coronary artery calcium (CAC) scoring and coronary angiography., Study Design: The study included 185 women (mean age 57+/-12 years) without known CAD and diabetes, with low or moderate risk for CAD based on traditional risk scoring. Coronary artery calcium scoring and coronary angiography were performed by MSCT, which included a segment-based plaque detection and characterization of calcification. The plaques were classified based on the luminal stenotic effect (>50%). Patients with = or >1 stenotic plaque were classified as having obstructive CAD. Angiographic findings were compared with calcium scores., Results: Coronary artery calcium scoring and coronary angiography detected CAD in 63 (34.1%) and 100 (54.1%) women, respectively. In both groups, women were significantly older and had higher prevalences of hypertension and dyslipidemia. Coronary angiography showed CAD in 41 women (41%; 14.6% were obstructive) without CAC. These women were significantly younger than those with a positive CAC score (p<0.01). Age (p<0.02) and hypertension (p<0.05) were found as independent predictors of CAD detected by coronary angiography., Conclusion: Multislice computed tomography identified a subset of low-risk women who might be at higher risk than that suggested by current risk stratification strategies. Women, especially having hypertension and dyslipidemia may be potential candidates for further risk stratification by MSCT coronary angiography.

- Abstract
Assessment and treatment of sexual dysfunction gain more importance in countries like Turkey where cardiovascular events are frequently seen in young adults. The mortality of cardiovascular events is reduced by primary percutaneous coronary angioplasty (PTCA), use of new thrombolytics in acute myocardial infarction (MI), and new drugs used in the treatment of heart failure. Because of the longer life expectancy, assessment of sexual functions and rehabilitation are getting more important in these patients. Since phosphodiesterase type 5 inhibitors (PDE 5) have been frequently utilized in the treatment of impotence, patients' and the doctors' attention have been directed towards cardiovascular risks of sexual activity. In recent years, this topic has become more important because several reports have stated the possible relationship between the use of PDE5 inhibitors and myocardial infarction. It is known, that in patients with cardiovascular diseases, sexual activity poses a low sudden death risk independent of PDE5 inhibitor use. In this review, the points that doctors should take into account while considering and treating the sexual dysfunction in patients with cardiovascular diseases are discussed.
