RESUMO
BACKGROUND AND AIMS: We aimed to investigate the relationship between triglyceride glucose (TyG) index and intracoronary thrombus burden in patients with ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). METHODS AND RESULTS: A total of 468 consecutive patients who were admitted with STEMI and underwent primary PCI were included in the study. TyG index was calculated as ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2]. According to the angiographic reclassified thrombolysis in myocardial infarction (TIMI) thrombus grade, patients were divided into two groups as small thrombus burden (STB) with TIMI thrombus grade 0-3, and large thrombus burden (LTB) with TIMI thrombus grade 4-5. TyG index was significantly higher in the LTB group than in the STB group (9.11 ± 0.86 vs 8.89 ± 0.62; p = 0.002). In multivariate analysis, TyG index was found to be an independent predictor of LTB in STEMI patients who underwent primary PCI [OR (95 % CI): 1.470 (1.090-1.982), p = 0.012]. The area under the curve (AUC) of TyG index predicting LTB was 0.568 (95 % CI 0.506-0.631; p = 0.023), with the best cut-off value of 8.87. In the classification according to TyG index cut-off value, the frequency of LTB was found to be significantly higher in the high TyG index group than in the low TyG index group (33.6 % vs 21.2 %; p = 0.003). CONCLUSION: TyG index, a valid surrogate marker of insulin resistance, is an independent predictor of LTB in STEMI patients who underwent primary PCI and can be used as an indicator of increased intracoronary thrombus burden.

Accessory chordae tendineae is an extremely rare anomaly. In this case report, we described a 61-year-old female patient newly diagnosed with the combination of an accessory mitral valve chordae extending from left atrium which is an extremely rare congenital anomaly and a bicuspid aortic valve. In our patient, three-dimensional echocardiography showed incremental value over two-dimensional echocardiography in the assessment of the exact localization and the extend of accessory chordea.

BACKGROUND: Using the tricuspid annular plane systolic excursion (TAPSE)/pulmonary arterial systolic pressure (PASP) ratio as an index of right ventricular load adaptability, we aimed to evaluate early changes in right heart contractile function of patients with group 1 pulmonary artery hypertension (PAH) after sequential combination PAH-specific therapy. METHODS: A total of 49 patients with group 1 PAH and 31 control participants were included in the study. The baseline clinical and echocardiographic data of the control and PAH group were compared. Subsequently, clinical and echocardiographic data of PAH patients before treatment and at 6 months after PAH-specific treatment were analyzed. RESULTS: A significant increase in the TAPSE/PASP ratio was found in patients at 6 months of PAH-specific treatment (0.25⯱ 0.14; 0.33⯱ 0.16, pâ¯< 0.001). Right atrial pressure (8â¯mmâ¯Hg [5-10]; 5â¯mmâ¯Hg [3-8], pâ¯< 0.001) and PASP (80.8⯱ 30.6â¯mmâ¯Hg; 65.9⯱ 25.7â¯mmâ¯Hg, pâ¯< 0.001) were significantly lower after sequential combination PAH-specific therapy. Negative correlations were found between the TAPSE/PASP ratio and Nterminal pro-B-type natriuretic peptide (râ¯= -0.524, pâ¯< 0.001), tricuspid regurgitation velocity (râ¯= -0.749, pâ¯< 0.001), right atrial area (râ¯= -0.298, pâ¯= 0.037), and right atrial pressure (râ¯= -0.463, pâ¯= 0.001). CONCLUSION: In patients with group 1 PAH, echocardiographic evaluation at the early stage of treatment (6 months) shows a significant improvement in the TAPSE/PASP ratio indicating right ventricular load adaptation. Comprehensive studies are needed on the routine use of the TAPSE/PASP ratio in the risk assessment of PAH patients.

BACKGROUND: The prognostic value of C-reactive protein/albumin ratio (CAR) is of import in cardiovascular diseases. Our aim was to evaluate the impact of the CAR in patients with asymptomatic abdominal aortic aneurysm (AAA) undergoing endovascular aneurysm repair (EVAR). MATERIAL AND METHOD: We retrospectively evaluated 127 consecutive patients who underwent technically successful elective EVAR procedure between December 2014 and September 2020. The optimal CAR cut-off value was determined by using receiver operating characteristic (ROC) curve analysis. Based on the cut-off value, we investigated the association of CAR with long-term all-cause mortality. RESULTS: 32 (25.1%) of the patients experienced all-cause mortality during a mean 32.7 ± 21.7 months' follow-up. In the group with mortality, CAR was significantly higher than in the survivor group (4.63 (2.60-11.88) versus 1.63 (0.72-3.24), p < 0.001). Kaplan-Meier curves showed a higher incidence of all-cause mortality in patients with high CAR compared to patients with low CAR (log-rank test, p < 0.001). Multivariable Cox regression analysis revealed that glucose ≥ 110 mg/dL (HR: 2.740; 95% CI: 1.354-5.542; p = 0.005), creatinine ≥ 0.99 mg/dL (HR: 2.957, 95% CI: 1.282-6.819, p = 0.011) and CAR > 2.05 (HR: 8.190, 95% CI: 1.899-35.320, p = 0.005) were the independent predictors of mortality. CONCLUSION: CAR was associated with a significant increase in postoperative long-term mortality in patients who underwent EVAR. Preoperatively calculated CAR can be used as an important prognostic factor.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a severe, life-threatening disorder despite the availability of specific drug therapy. A lack of endogenous prostacyclin secondary to downregulation of prostacyclin synthase in PAH may contribute to vascular pathologies. Therefore, prostacyclin and its analogs including inhaled iloprost may decrease pulmonary arterial pressure and ventricular pressure. METHODS: Here, we studied that acute effects of iloprost used in pulmonary vasoreactivity testing on the intracardiac conduction system in patients with PAH. A total of 35 (15 idiopathic PAH, 20 congenital heart disease) patients with PAH were included in this prospective study. Patients were divided into two groups: 22 patients with negative pulmonary vasoreactivity in group 1 and 13 with positive pulmonary vasoreactivity in group 2. Electrophysiological parameters including basic cycle length, atrium-His (AH) interval, His-ventricle (HV) interval, PR interval, QT interval, QRS duration, Wenckebach period, and sinus node recovery time (SNRT) were evaluated before and after pulmonary vasoreactivity testing in both groups. RESULTS: The AH interval (81 [74-93]; 80 [65.5-88], pâ¯= 0.019) and SNRT (907.7⯱ 263.4; 854.0⯱ 288.04, pâ¯= 0.027) was significantly decreased after pulmonary vasoreactivity testing. Mean right atrium pressure was found to be correlated with baseline AH (râ¯= 0.371, pâ¯= 0.031) and SNRT (râ¯= 0.353, pâ¯= 0.037). CONCLUSION: Inhaled iloprost can improve cardiovascular performance in the presence of PAH, primarily through a reduction in right ventricular afterload and interventricular pressure. Decreased pressure on the interventricular septum and ventricles leads to conduction system normalization including of the AH interval and SNRT due to resolution of inflammation and edema.

BACKGROUND: Carotid artery stenting (CAS) is being increasingly used as an alternative revascularization procedure to carotid endarterectomy; however, subclinical ischemic cerebral lesions after CAS remain as a matter of concern. Hence, we aimed to assess the clinical utility of the CHADS2 score in predicting subclinical ischemic events after CAS. METHODS: We prospectively evaluated 107 patients (mean age: 70.4 ± 6.6 years, male:77) who underwent CAS for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after CAS were excluded. The presence of new hyperintense lesion on diffusion-weighted imaging (DWI) without any neurological findings was considered as silent ischemia. Patients were classified into two groups as DWI-positive and DWI-negative patients. RESULTS: Among study population, 28 patients (26.2%) had subclinical embolism. The DWI-positive group had a significantly higher CHADS2 scores, older age, more frequent history of stroke, higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. Increased CHADS2 score was identified as one of the independent predictors of silent embolism (OR = 5.584; 95%CI: 1.516-20.566; p = .010), and CHADS2 score higher than 2.5 predicted subclinical cerebral ischemia with a sensitivity of 72% and a specificity of 71% (AUC: 0.793; 95% CI: 0.696 - 0.890; p < .001). CONCLUSIONS: CHADS2 score was able to predict the risk of periprocedural subclinical ischemic events in CAS and might be of clinical value in the management of patients with carotid artery stenosis.

AIM: Gender-related differences have been described in the clinical characteristics and management of patients with chronic heart failure with reduced ejection fraction (HFrEF). However, published data are conflictive in this regard. METHODS: We investigated differences in clinical and management variables between male and female patients from the ATA study, a prospective, multicentre, observational study that included 1462 outpatients with chronic HFrEF between January and June 2019. RESULTS: Study population was predominantly male (70.1%). In comparison to men, women with chronic HFrEF were older (66 ± 11 years vs 69 ± 12 years, P < .001), suffered more hospitalisations and presented more frequently with NYHA class III or IV symptoms. Ischaemic heart disease was more frequent in men, whereas anaemia, thyroid disease and depression were more frequent in women. No difference was seen between genders in the use rate of renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, or ivabradine, or in the proportion of patients achieving target doses of these drugs. Regarding device therapies, men were more often treated with an implantable cardioverter-defibrillator (ICD) and women received more cardiac resynchronisation therapy. CONCLUSION: In summary, although management seemed to be equivalent between genders, women tended to present with more symptoms, require hospitalisation more frequently and have different comorbidities than men. These results highlight the importance of gender-related differences in HFrEF and call for further research to clarify the causes of these disparities. Gender-specific recommendations should be included in future guidelines in HFrEF.

OBJECTIVES: Malnutrition has been shown to be associated with survival in a variety of diseases. Our aim is to evaluate the prognostic value of objective nutritional indexes indicating malnutrition, in patients underwent endovascular aortic replacement. METHODS: We retrospectively evaluated 149 consecutive patients who underwent technically successful endovascular aortic replacement operation between October 2010 and August 2019. Objective nutritional indexes, prognostic nutritional index, geriatric nutritional risk index and controlling nutritional status, scores were calculated using the preoperative data. Optimal cut-off values were obtained by receiver operating characteristic analysis. According to the cut-off values, we investigated the relationship between indexes and the long-term all-cause mortality. RESULTS: During mean 48.0 ± 30.3 months follow-up duration, in 47 of patients (31.5%), all-cause mortality were documented. In mortality group, prognostic nutritional index (42.8 ± 7.1 vs 51.3 ± 5.2, p < 0.001) and geriatric nutritional risk index (100.7 ± 10.1 vs 107.6 ± 9.2, p < 0.001) were significantly lower, controlling nutritional status score (2.0 (1.0-4.0) vs 1.0 (0.0-2.0), p < 0.001) was higher when compared to survivor group. Kaplan-Meier curves presented higher mortality incidence in malnutrition patients evaluated with objective nutritional indexes (Log-rang test, for all three indexes p < 0.001). Besides Cox-proportional hazard analysis showed all three nutritional indexes may be a predictive marker for all-cause mortality, prognostic nutritional index introduced more valuable data than other two indexes. CONCLUSIONS: Malnutrition is associated with significant increase in postoperative long-term mortality in endovascular aortic replacement patients. Preoperatively calculated objective nutritional indexes especially prognostic nutritional index can be used as an important prognostic tool.

AIM: The logistic clinical SYNTAX score (log CSS) is a combined risk scoring system including clinical and anatomic parameters; it has been found to be effective for the prediction of mortality in patients with ST-elevation myocardial infarction (STEMI). Coronary artery bypass grafting (CABG) in the primary treatment of acute myocardial infarction is still debated. In the present study, we aimed to evaluate the utility of log CSS to stratify the risk of in-hospital mortality in acute STEMI patients undergoing emergent CABG for primary revascularization. METHOD: In total, 88 consecutive patients with acute STEMI, who did not qualify for primary percutaneous coronary intervention and required emergent CABG were included in our study. Nine of 88 patients died during hospitalization. The study population was divided into two groups as in-hospital survivors and non-survivors. Log CSS and SYNTAX score (SS) were calculated for both groups and two groups were compared in terms of demographics, preoperative, intraoperative, postoperative characteristics, SS and log CSS. RESULTS: Log CSS was found to be an independent predictor of in-hospital mortality, log CSS > 10.5 had 89% sensitivity, 81% specificity (area under the curve: 0.927; 95% confidence interval: 0.855-0.993). Moreover, peak troponin level was an independent predictor of in-hospital mortality. Glucose level, cardiopulmonary resuscitation before operation, glomerular filtration rate, left ventricular ejection fraction, and Killip class were significantly associated with in-hospital mortality. CONCLUSION: Log CSS may improve the accuracy of risk assessment in patients who are undergoing emergent CABG for primary revascularization of STEMI.

INTRODUCTION: Aortic stenosis (AS) is the most common degenerative valvular heart disease that can affect left ventricular functions. Tp-e interval and Tp-e/QT ratio is a novel repolarization marker which is associated with adverse cardiovascular events in several cardiovascular diseases. In our study, our aim is to investigate the prognostic effect of Tp-e interval, Tp-e/QT and Tp-e/QTc ratios on mortality in patients who underwent successful surgical aortic valve replacement (AVR). METHODS: A total of three hundred seventy-five patients undergoing successful surgical AVR were included in this study. Then, patients were divided into two groups according to mortality as group 1 without mortality (342 patients) and group 2 with mortality (33 patients). Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were calculated for both groups. RESULTS: Tp-e interval (71 (63.7-77); 86 (84-88), p < .001), Tp-e/QT ratio (0.19 (0.17-0.20); 0.23 (0.22-0.23), p < .001) and Tp-e/QTc ratio (0.17 ± 0.02; 0.21 ± 0.01, p < .001) were higher in group 2 compared to group 1. In multivariate logistic regression analyses Tp-e interval (odds ratio [OR]: 1.315, 95% confidence interval [CI]: 1.203-1.437, p < .001), Tp-e/QT ratio (OR: 7.334, 95% CI: 3.274-1.643, p < .001) and Tp-e/QTc ratio (OR: 2.567, 95% CI: 4.106-1.605, p < .001) were found to be independent predictors of mortality. Additionally, a Kaplan-Meier survival analysis also revealed that long term survival was found to be significantly decreased in patients with higher Tp-e/QT ratio (Log-Rank p < .001) and Tp-e/QTc ratio (Log-Rank p < .001). CONCLUSION: Tp-e interval, Tp-e dispersion, Tp-e/QT, and Tp-e/QTc ratios are associated with worse prognosis after surgical AVR in patients with severe AS. All of them are also independent predictors of mortality.

Endomyocardial fibrosis (EMF), a restrictive cardiomyopathy characterized by subendocardial fibrosis, is commonly seen in tropical and subtropical regions. EMF involving the left ventricle presents with severe pulmonary hypertension (PH) and is a rare cause of PH in non-tropical areas. Multimodality imaging is important for accurate diagnosis, especially cardiac magnetic resonance imaging which is the cornerstone. Herein, we report the case of a patient who presented with heart failure symptoms and severe PH, and in whom EMF was diagnosed by multimodality imaging.

BACKGROUND: Postoperative atrial fibrillation (POAF) is associated with an increased risk of short and long-term stroke. Our aim is to identify the independent predictors of cerebrovascular accident (CVA) development in the patients who underwent isolated coronary artery bypass graft (CABG) surgery and developed POAF which lasted within 48 h. METHOD: 301 consecutive patients who underwent isolated CABG surgery in our institution between January 2015 and September 2019 and developed POAF which lasted within 48 h, were retrospectively analyzed. Oral anticoagulant (OAC) treatment was not started in any of these patients, and those who received OAC during follow-ups, were excluded from the study. The predictors of CVA development after mean 32.1± 17.9 months follow-up, were determined by using the Cox proportional hazards model. RESULTS: 20 (6.6%) patients developed CVA, in which 6 (2.0%) of them were in-hospital events. As a result of the multivariate analysis, being over 70 year-old, history of CVA, hypertension (HT), and left ventricular ejection fraction (LVEF) < 45% were determined as the independent predictors of CVA development over time. Having at least two of these factors could predict CVA development with sensitivity of 95.0% and specificity of 82.2%. This predictive value was better than the value obtained with CHA2DS2-VASc score. CONCLUSION: The risk factors which we have obtained, might be used to evaluate the risk of CVA development over time in the patients who underwent isolated CABG surgery and developed POAF which lasted within 48 h.

BACKGROUND: Although it has been shown that high mean platelet volume (MPV) is associated with target organ damage in hypertensive patients, the relationship between MPV and the development of long-term major adverse cardiovascular events (MACE) has not been thoroughly investigated. In this study, we investigated the relationship between MPV and long-term MACE in hypertensive patients. METHODS: From September 2011 to July 2017, 1507 patients with hypertension were included in this study. Ambulatory blood pressure monitoring was performed in all patients. Patients with chronic renal failure, cardiovascular disease, chronic systemic disease and white coat hypertension were excluded from the study. MACE were defined as myocardial infarction, stroke and cardiovascular mortality. Patients were followed-up until january 2020. RESULTS: The mean follow-up duration was 87 (83.3 ± 24.4) months, and 876 patients completed the study. MACE developed in 79 patients, while 797 patients were event-free. In univariate Cox regression analysis, age, diabetes mellitus (DM), MPV, creatinine, 24-hour systolic blood pressure, and non-dipper hypertension were found to be associated with the development of MACE. In multivariate Cox regression analysis, creatinine and 24-hour systolic blood pressure lost significance, and age, DM, non-dipper hypertension and MPV were found to be independent predictors for MACE development (p < 0.001, p < 0.001, p = 0.044, and p = 0.049, respectively). CONCLUSIONS: MPV, age, DM, and non-dipper hypertension were independent predictors of long-term MACE in hypertensive patients.
RESUMO
BACKGROUND: The determinants of left ventricular (LV) recovery after successful revascularization in ST-elevation myocardial infarction (STEMI) patients are not clear. In addition, the relationship between growth differentiation factor15 (GDF-15) and left ventricular ejection fraction (LVEF) improvement is also unknown. This study hypothesizes that a low GDF-15 level would be associated with LVEF recovery. METHODS: One hundred and sixty-one STEMI patients were included in this study. Echocardiographic examinations were performed before and 12-18 weeks after discharge. The patients were divided into three groups according to the changes in LVEF as 62 patients with ≥ 10% change, 47 patients with 1-9% change, and 52 patients ≤ 0% change. LV recovery was defined as ≥ 10% LVEF improvement and the predictors of LV recovery were investigated. Moreover, two groups were created according to GDF-15 values, and the follow-up/baseline echocardiographic parameters were compared between these groups. RESULTS: LV recovery was detected in 38.5% of the patients. Low baseline LVEF [odds ratio (OR): 0.85, 95% confidence interval (CI) 0.82-0.94, p = 0.001], low GDF-15 (OR: 0.79, 95% CI 0.68-0.93, p = 0.004), previous angina (OR: 2.34, 95% CI 1.10-4.96, p = 0.027), and symptom-to-balloon time (OR: 0.97, 95% CI 0.95-1.00, p = 0.043) were independent predictors of LV recovery. The ratios of follow-up/baseline LV end-diastolic volume index, LV end-systolic volume index and wall motion score index were lower in the low GDF-15 group (0.96 vs. 1.04, p < 0.001; 0.96 vs. 1.10, p < 0.001; 0.89 vs. 0.96, p < 0.001). Moreover, being in the low GDF-15 group was associated with LV recovery (OR: 2.93, 95% CI 1.43-6.02, p = 0.001). CONCLUSIONS: Lower GDF-15 level was associated with better LV improvement and less adverse remodeling in STEMI patients.
RESUMO
Left atrial (LA) invasion by lung cancer via hematogenous pathways is relatively uncommon. Herein we report the case of a 68-year-old male without any medical history, in whom lung cancer was diagnosed by transesophageal echocardiographic detection of the LA and left ventricle tumoral invasion via the left upper pulmonary vein. The primary source of tumor was found out by computed tomography.

BACKGROUND: The aim of this study was to investigate the relationship between QT (QTc) interval, Tp-e interval, Tp-e/QTc ratio, 5-year sudden cardiac death (SCD) risk score, and late gadolinium enhancement (LGE) detected by CMR in hypertrophic cardiomyopathy (HCM) patients. METHOD: A total of 74 consecutive patients who underwent CMR with HCM diagnosis were included in the study. These patients were divided into two groups according to the presence of LGE on CMR. All patients underwent detailed echocardiography and QTc interval, Tp-e interval, and Tp-e/QTc ratios and 5-year SCD risk scores were calculated. These parameters were compared for two groups. RESULTS: CMR revealed LGE in 32 (43.2%) of 74 HCM patients. In the group with LGE, significantly higher QTc interval (p = 0.002), Tp-e interval (p < 0.001), Tp-e/QTc ratio (p = 0.004), and 5-year SCD risk score were detected. In addition, QTc interval, Tp-e interval, Tp-e/QTc ratio, maximum wall thickness, left ventricular mass index, 5-year SCD risk score, and cardiac fibrosis index were found to be correlated with various degrees in correlation analysis. Also, Tp-e interval is found to be an independent predictor of LGE detected by CMR in HCM patients (p = 0.017, OR [%95 CI] = 1.017 [1.001-1.034]). In addition, the Tp-e interval can detect the LGE with a sensitivity of 64.3% and a specificity of 84.2% at 99.4 ms. (p < 0.001, AUC [95% CI] = 0.790 [0.676-0.905]). CONCLUSION: The Tp-e interval can be used to optimize SCD risk stratification in HCM patients and determine which patients will benefit from implantable cardioverter-defibrillator (ICD) treatment.

AIM: Rheumatic heart disease is a common cause of valvular disease, especially in developing countries. Echocardiography is the gold standard investigation modality for cardiac valves. In rheumatic mitral stenosis (MS), three-dimensional transesophageal echocardiography (3D TEE) provides better alignment of the image plane at the mitral tips and more accurate and reproducible planimetric measurement of mitral valve area (MVA). Cardiac magnetic resonance (CMR) is a new method that provides evaluation of cardiac anatomy and function noninvasively. Previous studies showed strong correlation between planimetric MVA measured by two-dimensional transthoracic echocardiography and CMR. We aimed to compare the planimetric MVAs assessed by 3D TEE and CMR in rheumatic MS patients. To best of our knowledge, this is the first study that compares 3D TEE and CMR for the assessment of the planimetric MVA in rheumatic MS. METHODS: We retrospectively evaluated 28 rheumatic MS patients who underwent 3D TEE and ECG-gated CMR. 3D TEE planimetric MVAs were measured manually by multiplanar reconstruction (MPR) method and CMR planimetric MVAs were measured manually on short-axis cine images. Then, 3D TEE and CMR measurements were compared. RESULTS: A total of 28 patients' (mean age 44 ± 12, 82.1% female) planimetric 3D TEE MVAs (1.00 ± 0.20 cm2 ) and CMR MVAs (1.04 ± 0.17 cm2 ) were found to be highly correlated (P < 0.0001, r: 0.744) with Pearson correlation analysis. Bland-Altman analysis showed strong agreement between two techniques. CONCLUSION: For the diagnosis and the follow-up of rheumatic MS, planimetric CMR MVA is an alternative noninvasive method which highly correlates with planimetric 3D TEE MVA.

Myxomas are the most common cardiac primary tumors; however, left ventricular myxomas are extremely rare. We describe a young female patient with a giant left ventricular myxoma causing partial obstruction of the left ventricular outflow tract, who underwent successful surgical resection. Real-time three-dimensional echocardiography yielded incremental value to two-dimensional echocardiography by allowing better assess of the true size, extent, attachment, and morphology of the tumor. © 2017 Wiley Periodicals, Inc.

Hydatid disease is a human parasitic infection caused by the larval stage of Echinococcus granulosus. The most common locations for hydatid cysts are the liver and lungs. Cardiac involvement is rare, and isolated cardiac hydatid cysts are even more unusual. We report the case a 48-year-old female patient with an isolated huge cardiac hydatid cyst involving both the left ventricular free wall and the pericardium, and presenting with atypical chest pain. © 2017 Wiley Periodicals, Inc.
