Measurement of epicardial fatty tissue thickness has a diagnostic value in lichen planus patients and is associated with fibrinogen to albumin ratio and neutrophil to lymphocyte ratio.

OBJECTIVE: Lichen planus (LP) is one of the chronic inflammatory diseases. Epicardial fatty tissue (EFT) is the adipose tissue in which pro-inflammatory and pro-atherogenic hormones and cytokines are secreted. We planned to investigate the predictive value of EFT in LP patients by evaluating together with Fibrinogen to albumin ratio (FAR) other inflammation markers. MATERIALS AND METHODS: A total of 53 consecutive LP patients and 57 healthy controls were enrolled in this single-center, prospective, case-control study. Demographic data were recorded; blood tests were obtained from both groups. Then, EFT thickness was measured by echocardiography. RESULTS: Fibrinogen, FAR, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio, and EFT thickness were higher in LP patients (p < 0.05, for all). EFT was positively correlated with FAR (r = 0.306, p = 0.001), NLR (r = 0.240, p = 0.011), and PLR (r = 0.297, p = 0.002). ROC analysis indicated that FAR could predict LP with a sensitivity of 83 % and a specificity of 44 %; NLR could predict LP with a sensitivity of 80 % and a specificity of 46 %; EFT could predict LP with a sensitivity of 79 % and a specificity of 54 %. In the binary logistic regression analysis NLR, FAR, and EFT were found to be independent predictors of LP. CONCLUSION: We found a relationship between LP and FAR together with other inflammation parameters NLR, and PLR. We demonstrated for the first time that FAR, NLR and EFT were independent predictors of LP. Also, there was a significant relationship between these parameters and EFT (Tab. 4, Fig. 1, Ref. 30).

Coronary sinus collapsibility index and inferior vena cava collapsibility index can predict right atrial pressure in patients undergoing right heart catheterization.

BACKGROUND: The aim of the study is to investigate the relationship between the diameters and collapsibility indices of coronary sinus (CS) and inferior vena cava (IVC) and invasively measured right atrial pressure (RAP), and to determine whether these parameters have predictive value on RAP. METHODS: A total of 136 patients undergoing right heart catheterization due to pulmonary arterial hypertension were included in the study prospectively. CS diameters, IVC diameters, CS collapsibility index (CSCI), and IVC collapsibility index (IVCCI) were measured by echocardiography before catheterization. Pearson correlation analysis was used to compare the parameters. Receiver operating characteristics (ROC) curve analysis was used to determine the predictive value of the CS and IVC collapsibility indices in predicting RAP. RESULTS: Patients were divided into two groups as invasively measured RAP≥10 mm Hg (n:57) and RAP < 10 mm Hg (n:79). In the group with RAP≥10 mm Hg, IVC and CS diameters were higher than in the group with RAP < 10 mm Hg, while the IVCCI and CSCI were lower (p < 0.001). A negative correlation was observed between CSCI and IVCCI and RAP. Also, a positive correlation was observed between CSCI and IVCCI. Optimal cut-off value for IVCCI was 46.1 with a sensitivity of 75%, and specificity of 79.7%. Optimal cut-off value for CSCI was 39.2 with a sensitivity of 75.4%, and specificity of 88.6%. CONCLUSION: CS and IVC diameters and collapsibility indices measured by echocardiography were found to be associated with invasively measured RAP, and may be used together for estimating RAP.

Usefulness of novel Martin/Hopkins and Sampson equations over Friedewald equation in cardiology outpatients: A CVSCORE-TR substudy.

BACKGROUND AND AIMS: The Friedewald equation (LDL-Cf) is known to produce inaccurate estimations of low-density lipoprotein cholesterol (LDL-C) when triglycerides are high (>400 mg/dL) or LDL-C is low (<70 mg/dL). The Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) equations were developed to overcome these limitations, but few data are available to assess whether these equations offer incremental usefulness over LDL-Cf. Our aim was to understand whether there was any incremental usefulness of novel equations on decisions regarding patient management. METHODS: Four thousand one hundred and ninety-six cardiology patients who were included in a multicentre registry database were analysed. Each patient was assigned to a cardiovascular risk class using the SCORE (Systematic COronary Risk Evaluation) algorithm, and relevant European guidelines were used to assess LDL-C targets. RESULTS: Compared with LDL-Cmh and LDL-Cs, LDL-Cf was able to correctly identify 96.9%-98.08% of patients as within or outside the LDL-C target, respectively, and 1.95%-2.8% of patients were falsely identified as being within the LDL-C target. Kappa coefficients for agreement between LDL-Cf vs LDL-Cmh and LDL-Cf vs LDL-Cs were 0.868 and 0.918 (P < .001). For patients not on cholesterol-lowering drugs, the decision to initiate treatment would be different in 1.2%-1.8% of cases if LDL-Cs or LDL-Cmh were used, respectively. For those already on cholesterol-lowering drugs, decisions regarding treatment intensification would be different in 1.5%-2.4% of cases if LDL-Cs or LDL-Cmh were used. CONCLUSIONS: In most cardiology outpatients, the Friedewald equation has excellent agreement with the novel Martin/Hopkins and Sampson equations, and treatment decisions should not change in most patients.

Cardiovascular risk unawareness is common in individuals admitting to cardiology outpatient clinics in Turkey: the CVSCORE-TR study.

OBJECTIVES: Cardiovascular "risk" is an abstract concept that is frequently misunderstood by the general public. However, correct estimation of one's own cardiovascular risk is important as risk unawareness is associated with noncompliance with interventions aimed to reduce risk burden. Knowing the prevalence and factors linked with an increased probability of risk unawareness are therefore important to develop strategies aimed to increase risk awareness. Aims. To study prevalence of risk unawareness and to understand risk markers associated with risk underestimation and overestimation. Design. A total of 1716 participants were enrolled to the study in 33 centers across Turkey. Relevant demographic and clinical data were collected by direct interview. Cardiovascular risk of the participants was calculated using SCORE risk charts. Results. Ten-year risk for a fatal cardiovascular event was calculated as low in 633 (36.8%), intermediate in 513 (29.9%) and high-very high in 570 (33.2%) participants, respectively. According to these findings, 34.6% (n = 593) of the participants estimated their risk correctly, whereas 22.7% (n = 390) of the participants overestimated and 42.7% (n = 733) of the participants underestimated their risk. Male gender was the sole factor that was associated with an increased risk of underestimation, while having hypertension, significant valve disease or atrial fibrillation was associated with increased odds for risk overestimation. Conclusions. Only one-thirds of the sample was aware of their calculated risk for cardiovascular mortality and risk underestimation was the most common mode of risk unawareness, prompting concerns on the possible impact of the latter on adherence to the strategies aimed to reduce cardiovascular risk.

Melatonin protects against streptozotocin-induced diabetic cardiomyopathy through the mammalian target of rapamycin (mTOR) signaling pathway.

BACKGROUND: Several studies demonstrated that the overexpression of mammalian target of rapamycin (mTOR) signaling protein is associated with cardiomyopathy. However, the effect of mTOR on the heart in hyperglycemic condition is still controversial. OBJECTIVES: We aimed to investigate the expression of mTOR and antioxidant enzyme activity in cardiac hypertrophy in rats with streptozotocin-induced diabetes mellitus (DM), and the effects of the melatonin on diabetic cardiomyopathy (DCM). MATERIAL AND METHODS: Forty male Wistar rats were used as the experimental animals. The rats were divided into 4 groups (10 animals in each): group 1 (control group), group 2 (ethanol vehicle group), group 3 (iatrogenically DM-induced group), and group 4 (group given melatonin after iatrogenical DM induction). Streptozotocin was injected intraperitoneally to group 3 and 4 to induce experimental type 1 DM. Melatonin was injected intraperitoneally at a dose of 50 mg/kg/day for 56 days to group 4. We investigated expression of mTOR levels in heart muscle fibers of all groups. Laboratory analysis and transthoracic echocardiography were performed. RESULTS: Melatonin increased the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), which were reduced due to hyperglycemia. The mTOR expression levels were significantly higher in group 3 (DM group) compared with controls, whereas melatonin treatment significantly decreased the levels of mTOR expression in group 4 (melatonin + DM group). Diabetic rats developed myocardial hypertrophy with preserved cardiac function. CONCLUSIONS: Cardioprotective effect of melatonin may reduce damages caused by DM in the heart muscle fibers through the mTOR signaling pathway.

Aortic-flow propagation velocity is associated with proteinuria and left ventricular hypertrophy in newly diagnosed hypertensive patients.

OBJECTIVE: Subclinical target organ damage (TOD) is an important long-term complication of hypertension and is associated with cardiovascular events and death. Aortic-flow propagation velocity (APV) is one of the arterial stiffness parameters. The aim of this study was to investigate the predictive value of APV on left ventricular hypertrophy (LVH) and proteinuria. METHODS: A total of 149 newly diagnosed HT patients were included in the study. Urine samples and blood tests were obtained from each patient for diagnosis of proteinuria. All patients underwent echocardiographic examination. All patients' APV measurements, carotid intima-media thicknesses (CIMT), and ankle-brachial indexes (ABI) were measured and recorded. RESULTS: The LVH (+) group consisted of 47 patients, and the LVH (-) group consisted of 102 patients. The proteinuria (+) group consisted of 32 patients, and the proteinuria (-) group consisted of 117 patients. Average CIMT was significantly higher in both proteinuria (+) and LVH (+) groups compared with the (-) groups. ABI and APV were significantly lower in both proteinuria (+) and LVH (+) groups compared with the (-) groups. APV was negatively correlated with LVH, proteinuria, and CIMT and positively correlated with ABI. In the multivariate binary logistic regression analysis, APV was the significant independent predictor of proteinuria. Additionally, APV and ABI were found to be independent predictors of LVH or/and proteinuria. CONCLUSION: Hypertensive patients who had TOD had worse consequences of APV, CIMT, and ABI. APV had a powerful predictive value to identify the patients with higher risk of TOD among newly diagnosed hypertensive patients.

Relationship between interleukin-17A and isolated coronary ectasia.

The aim of this study was to evaluate serum interleukin (IL)-17A levels in patients with coronary artery ectasia (CAE), the relationship between IL and 17A and CAE, and to determine the relationship between the severity of coronary ectasia and the level of IL-17A. In total, 41 patients (19 female and 22 male) with ischemic symptoms whose non-invasive cardiac tests were positive for myocardial ischemia, and in whom coronary artery ectasia were detected after coronary angiography, and 45 patients (32 female and 13 male) with normal coronary arteries were included in this study. Echocardiographic assessments were performed. Serum IL-17A levels of all patients were evaluated using an enzyme-linked immunosorbent assay. IL-17A levels of the group with isolated coronary artery ectasia were significantly higher compared with the control group (4.86 ±â€¯3.24 and 1.37 ±â€¯1.56 ng/ml, respectively; p < 0.001). There was no correlation between the levels of IL-17A and the extension of the CAE, but IL-17A levels were high in both groups. CAE patients have significantly increased levels of IL-17A, fibrinogen, and RDW compared to patients with normal coronary arteries. It was demonstrated that increased levels of IL-17A were associated with ectasia formation in CAE patients.

Melatonin protects against streptozotocin-induced diabetic cardiomyopathy by the phosphorylation of vascular endothelial growth factor-A (VEGF-A).

The aim of the present study is to investigate if the melatonin has any protective effect on diabetic cardiomyopathy and antioxidant enzymes via phosphorylation of vascular endothelial growth factor-A (VEGF-A). A total of 40 male Wistar rats were enrolled in the study. Rats were divided into four groups: group 1 (control, n=10), group 2 (DM, n=10), group 3 (melatonin, n=10), and group 4 (melatonin+DM, n=10). Melatonin was injected intraperitoneally at a dose of 50 mg/kg/day for 56 days to group 3 and group 4. We investigated expression and phosphorylation of the VEGF-A in coronary vessels of all groups. Staining intensities, biochemical, immunohistochemistry analysis, and transthoracic echocardiography were performed. In comparison to the group 1, DM induced a decrease in p-VEGF-A in coronary vessels of group 2. The lower constitutive phosphorylation of VEGF-A in the group 2 was also increased in coronary vessels after melatonin treatment (p<0.05). Diabetic rats developed myocardial hypertrophy with preserved cardiac function (p<0.05). Cardio-protective effect of melatonin may reduce the damages of diabetes mellitus on the heart muscle fibers and coronary vessels via the phosphorylation of VEGF-A. Melatonin-dependent phosphorylation of VEGF-A in coronary angiogenesis may be associated with the physiological as well as with the pathological cardiac hypertrophy.

Compliance With Dyslipidemia Guidelines in Daily Practice: How Effective Is Cardiovascular Risk Prevention?

PURPOSE: Cardiovascular disease (CVD) due to atherosclerosis is the leading cause of early mortality and morbidity. The current European guidelines on CVD prevention in clinical practice recommend the use of the Systematic Coronary Risk Estimation (SCORE) system. The current American Heart Association guidelines recommend the use of the new pooled cohort risk assessment equations to estimate the 10-year atherosclerotic CVD risk. The purpose of this article was to investigate the compliance of dyslipidemia guidelines in daily practice in patients with dyslipidemia or who have risk factors for CVD. METHODS: The study group consisted of 500 outpatients who had dyslipidemia or risk factors for CVD. The risk level was computed according to the European and American Heart Association guidelines. Therapeutic LDL-C targets were identified based on the calculated risk level. Therapeutic target levels were compared based on the dosage of statins used and achievement of the LDL-C goal in daily practice according to the risk levels. FINDINGS: According to the European dyslipidemia guidelines, 231 patients were in the very-high/high-risk group, and 106 patients (45.9%) achieved the LDL-C target (<100 mg/dL); 210 patients were in the moderate-risk group, and 156 (74.3%) patients achieved the LDL-C target (<115 mg/dL); and 59 patients were in the low-risk group, and 55 (93.2%) patients achieved the LDL-C target (<155 mg/dL). Univariate and multivariate logistic regression analyses revealed that the LDL-C level and presence of coronary artery disease were significantly reverse associated with achievement of the LDL-C goal (both, P < 0.001). IMPLICATIONS: Our results showed that the majority of patients were in the very-high/high-risk group in daily practice. Although the European dyslipidemia guidelines are more likely to be used in daily practice, achievement of the guidelines-recommended treatment goals was low.

ST segment elevation myocardial infarction (STEMI) patients are more likely to achieve lipid-lowering treatment goals: A retrospective analysis of patients presenting with first acute coronary syndromes.

Statin nonadherence or discontinuation is associated with increased cardiovascular events. Many factors related to the physicians or the patients are influential in this. We aimed to compare the compliance with statin therapy between the patients who first presented with ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina pectoris (UA) based on the target achievement according to the current dyslipidemia guidelines.We retrospectively acquired all the information about demographic characteristics, in-hospital revascularization procedures, prescribed treatments, and index and up to 6-month follow-up laboratory results of the first acute coronary syndrome patients. Acute coronary syndrome patients were divided into 3 groups as STEMI, NSTEMI, and UA.The STEMI group consisted of 260 patients, NSTEMI group consisted of 560 patients, and UA group consisted of 206 patients. Seventy-six percent of patients underwent percutaneous coronary interventions, 18.3% were managed medically, and 5.7% were referred for coronary artery bypass grafting. There was a significant decrease in low-density lipoprotein-cholesterol (LDL-C) values with the statin treatment at the follow-up in all 3 groups (for all P < .001). In the STEMI group, the percentage of those achieving the target LDL-C level was significantly higher than those who did not achieve the target according to both The American College of Cardiology/American Heart Association (ACC/AHA) and European Society of Cardiology dyslipidemia guidelines. The LDL-C target achievement rates were also higher in the STEMI group than in the NSTEMI and UA groups.Our study concluded that statin treatment goals were more attained in STEMI patients than NSTEMI and UA. All physicians should encourage lifelong intensive statin treatment in UA and NSTEMI patients such as STEMI patients.

Assessment of left atrial function using speckle tracking echocardiography in ankylosing spondylitis: a case-control study.

The aim of this study is to assess the left atrium (LA) deformation parameters by using 2D speckle tracking echocardiography (2D-STE) in ankylosing spondylitis (AS) patients and to evaluate the relationship between these parameters and AS clinical indexes. 30 patients with AS (22 males, 8 females) and 30 healthy individuals (19 males, 11 females) were enrolled in this study. Transthoracic echocardiography was performed to both groups. Besides the conventional echocardiographic parameters, the LA strain parameters; including systolic-reservoir (LA S-S), early diastolic-conduit (LA S-E), late diastolic-contraction (LA S-A) were measured. No significant difference was found between two groups in terms of conventional echocardiographic parameters except mean deceleration time (DT). Mean DT was prolonged in the AS patients compare with the control group (173.5 ± 22.5 vs. 155.3 ± 36.7, p = 0.025). In the AS patients, LA S-S (48.3 ± 9.4 vs. 56.9 ± 10.1, p = 0.001), LA S-E (26.4 ± 6.4 vs. 31.6 ± 7.3, p = 0.005) and LA S-A (21.9 ± 4.7 vs. 25.4 ± 5.7, p = 0.013) values were statistically lower than the control group. Also a negative correlation was observed between the Bath Ankylosing Spondylitis Metrology Index (BASMI) and LA S-S (r = - 0.509, p = 0.004), LA S-E (r = - 0.501, p = 0.005). Our study demonstrated that 2D-STE is a useful method to determine the left atrial involvement in AS patients without the clinical evident of cardiovascular disease.

Rupture of Sinus of Valsalva Aneurysm into Left Atrium in a Patient who is a Candidate for Hepatic Transplantation.

Sinus of valsalva aneurysm (SVA) is a rare cardiac disease. The most common complication of SVA is rupture into the right atrium or right ventricle. Rupture into the left chambers is very rare. Patients with ruptured SVA are likely to die of heart failure or endocarditis. We present a 29-year-old man who was hospitalized for hepatic transplantation with rupture of SVA. Transthoracic echocardiography and transesophageal echocardiography showed rupture of a noncoronary SVA into the left atrium. Mitral valve infective endocarditis developed and surgery was planned for the patient, but the patient died due to multiple organ dysfunction syndrome.

Evaluation of atrial electromechanical functions in dipper and nondipper hypertension patients using left atrial strain P-wave dispersion and P terminal force.

OBJECTIVE: Nondippers are known to carry a high risk of cardiovascular morbidity and mortality. The aim of this study was to investigate the effects of dipper and nondipper status of hypertension on left atrial (LA) systolic and diastolic functions using two-dimensional speckle tracking echocardiography (2D-STE), P-wave dispersion (PWD), and P terminal force (PTF) in hypertensive patients. METHODS: A total of 72 patients and 39 healthy individuals were included in the study. The patients were classified as nondippers if their daytime ambulatory systolic and diastolic blood pressure did not decrease by at least 10% during the night. Atrial electromechanical delay times, LA strain values were obtained by 2D-STE with automated software and compared between the groups. PWD and PTF data were calculated on the electrocardiography. RESULTS: Inter-atrial (dippers: 25.5 ± 3.9, nondippers: 32.2 ± 7.4, P < .001), left-atrial (dippers: 14.9 ± 3.7, nondippers: 18.2 ± 6.0, P = .016), and right atrial (dippers: 10.5 ± 2.1, nondippers: 14.2 ± 5.2, P < .001) electromechanical delay times were significantly longer in nondippers. LA strain S (dippers: 34.2 [29.7-38.7], nondippers: 27.7 [22.7-32.2], P < .001), LA strain E (dippers: 18.2 [16.6-20.1], nondippers: 14.4 [11.6-16.8], P < .001), and LA strain A (dippers: 15.8 [13.5-17.9], nondippers: 12.7 [9.9-14.5], P < .001) were significantly lower in nondippers. Nondippers also had an increased values of maximum P-wave duration (dippers: 0.117 [0.10-0.12], nondippers: 0.126 [0.12-0.14], P < .001), PWD (dippers: 0.062 [0.06-0.07], nondippers: 0.069 [0.06-0.08], P = .004), and PTF (dippers: 0.055 ± 0.02, nondippers: 0.066 ± 0.02, P = .02). CONCLUSION: Nondipping pattern in hypertensive patients had a worse cardiac remodeling, and impaired mechanical LA function compared with dipping pattern. The PWD and PTF findings support these changes.

Development of massive pulmonary embolism during echocardiographic imaging: A case report.

RATIONALE: Pulmonary embolism (PE) is a common diagnostic consideration for patients who present to the emergency department (ED) with chest pain, dyspnea, or both. In addition, PE has a very high mortality in patients who are hemodynamically unstable. An electrocardiography, bedside transthoracic echocardiogram, and computed tomography pulmonary angiogram are usually performed to confirm the diagnosis. PATIENT CONCERNS: A 53-year-old man was admitted to the cardiology clinic with complaints of dyspnea, chest pain, and general weakness after walking. He had a history of hypertension and smoking. DIAGNOSIS: During synchronous recording of echocardiographic images, a large mobile thrombus detached from the right atrium, and first embolized to the right ventricle and then to the main pulmonary artery from the right heart chambers. Soon after, shortness of breath developed which clinically worsened the patient. Transthoracic echocardiogram which demonstrated the thrombus in the pulmonary artery or right heart chambers was suspected of causing acute massive PE. INTERVENTIONS: The patient was transferred to Critical Care Unit for monitoring; 100 mg of alteplase was initiated immediately and alleviated the hemodynamic instability within 2 hours of intravenous administration. OUTCOMES: To the best of our knowledge, this is the first synchronous echocardiographic recording showing the embolization of a thrombus from the right atrium, first to the right ventricle and then to the main pulmonary artery. LESSONS: Transthoracic echocardiography provides a safe, rapid, and noninvasive diagnostic tool for evaluation of suspected massive PE. Thrombolytic therapy is useful for treating acute massive PE that leads to hemodynamic instability.

[Congenitally corrected transposition of the great arteries in patient with atrial septal defect and acute inferior segment myocardial infarction]. / Ileri yasta akut inferiyor miyokart enfarktüsü ile basvuran ve atriyal septal defekt anomalisinin eslik ettigi dogumsal düzeltilmis büyük arter transpozisyonu.

Congenitally corrected transposition of the great arteries is a rare abnormality accounting for approximately 1% of clinically apparent congenital heart disease. Age at time of diagnosis and survival rate vary and depend on associated anomalies, including pulmonary stenosis, ventricular septal defect, atrial septal defect, atrioventricular block, and atrioventricular valve regurgitation. Reported cases of corrected transposition of the great arteries with single coronary ostium anomaly and atrial septal defect are very rare. Described in the present report is the case of a 55-year-old male who presented with acute inferior ST-segment elevation myocardial infarction and coincidental single coronary ostium arising from the right sinus of Valsalva, as observed on coronary angiography. Successful balloon angioplasty and stenting of the circumflex artery were performed. Echocardiography demonstrated the corrected transposition of the great arteries with negative contrast enhancement between the atrial chambers. The patient was discharged with medical therapy on the eighth postoperative day. To our knowledge, the present is the first report to describe corrected transposition of the great arteries, atrial septal defect, single coronary ostium, and acute myocardial infarction as comorbidities.

Red cell distribution width and neutrophil-to-lymphocyte ratio predict left ventricular dysfunction in acute anterior ST-segment elevation myocardial infarction.

OBJECTIVES: Red cell distribution width (RDW) and neutrophil-to-lymphocyte ratio (NLR) are the two markers used to determine risk of mortality and adverse cardiovascular outcomes in patients with acute myocardial infarction. The relationship between RDW, NLR, and left ventricular (LV) systolic functions has not been reported. In this report, we aimed to investigate the relationship between RDW, NLR, and LV systolic function in anterior ST-segment elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention (PCI). METHODS: RDW and NLR were measured on admission in 106 STEMI patients treated with primary PCI. Patients were divided into two groups according to left ventricular ejection fraction (LVEF), as Group I (systolic dysfunction, LVEF <50%) and Group II (preserved global left ventricle systolic function, LVEF ⩾50%). The first group included 47 patients and the second group included 59 patients. RESULTS: Mean RDW and NLR were significantly higher in Group I compared to Group II [13.7 ± 0.9% vs. 13.4 ± 0.7%, p = 0.03 and 5.86 (range, 0.66-40.50) vs. 2.75 (range, 0.51-39.39), p = 0.013, respectively]. CONCLUSION: Increased RDW and NLR on admission, in anterior STEMI patients treated with primary PCI are associated with LV systolic dysfunction.
