Backgrounds and aims: Cardiovascular calcification is an important cause of morbidity and mortality in hemodialysis (HD) patients. Vascular and valvular calcification are indicators of increased tissue calcification. The relationship of osteopontin (OPN) - which is known as a vascular calcification inhibitor- and fibroblast growth factor-23 (FGF-23) - which its related to vascular calcification, as recently shown - to valvular calcification is unknown. In this cross-sectional study, we examined the relationship between heart valve calcification, serum OPN, and FGF-23 levels. Materials and methods: 85 adults who were on HD treatment for at least 6 months were included in the study. Echocardiographic evaluation was made with the General Electric echocardiography device and the same cardiologist. FGF-23 and osteopontin levels were measured by ELISA. Results: 54% of our patients were male, mean age was 49.8 +/- 15.1 years, and mean HD duration was 52.5 +/- 39.6 months. 34% of the patients were diabetic. and 17.6% had a history of coronary artery disease. 1.25 mmol/L calcium were used as dialysate calcium in 84.7% of the patients. 60% of the patients were on vitamin D replacement therapy. and 7.1% were receiving cinacalcet treatment. Valvular calcification ratio of the patients was 44%. Mean FGF-23 level was 682 +/- 771.7 pg/mL, and mean OPN level was 22.2 +/- 8.2 ng/mL. When the patients with and without heart valve calcification were compared. the group with heart valve calcification was older and had lower serum OPN levels. There were differences between the groups on left atrial diameters, left ventricular end-diastolic diameters, and posterior-wall thicknesses. In the logistic regression analysis, it was seen that age and serum OPN levels were predictors of valvular calcification. Conclusion: Serum osteopontin level is associated with heart valve calcification in HD patients, but there was no relationship found with FGF-23. Further research is needed on the subject.

BACKGROUND Ankylosing spondylitis (AS) is a systemic inflammatory disease, and cardiac dysfunction has not been clearly described clinically. High-sensitivity cardiac troponin T (hs-cTnT) is a noninvasive marker for subclinical myocardial injury. OBJECTIVE In this study, we aimed to investigate any relationship between hs-cTnT and left ventricular (LV) function evaluated via tissue Doppler imaging in AS patients with no known cardiac risk factor. METHODS Our study used a cross-sectional case protocol design and was conducted between January 2016 and June 2016. In total, 40 AS patients (17 females and 23 males) were age and sex matched with healthy volunteers (20 females and 20 males) and enlisted for this study. Detailed transthoracic echocardiography was performed, and tissue Doppler imaging was used to assess systolic and diastolic functions. High-sensitivity cardiac troponin T levels were measured and compared between 2 groups. RESULTS Compared with control subjects, AS patients had lower early (Em)/late (Am) diastolic myocardial velocities, mitral annular plane systolic excursion, and end-diastolic distance from the mitral annulus to the LV apex. Conversely, they had greater systolic myocardial velocity (Sm), isovolumetric relaxation time, and displacement index (p < 0.001, for all). Higher hs-cTnT levels were measured in AS patients (0.45 ± 0.22 vs. 1.11 ± 0.27, p < 0.001), and multivariate logistic regression analyses revealed that hs-cTnT was an independent predictor of LV diastolic dysfunction in AS patients. CONCLUSIONS These data show that AS patients had impaired LV functions and increased hs-cTnT levels. Tissue Doppler imaging may be a useful tool for detection of early functional LV abnormalities, and hs-cTnT may be valuable biomarker of diastolic LV dysfunction in AS patients.

Background: Majority of the incidentally discovered adrenal masses, called adrenal incidentaloma (AI), are nonfunctioning adrenal adenomas. The appropriate management of AI is still a matter debate, so it is necessary to investigate their associated morbidity. However, data regarding morphological and functional cardiac alterations are limited in this group. Objective: In this study, we aimed to assess cardiac structural and functional characteristics and atrial conduction properties in patients with nonfunctioning AI. Methods: Thirty patients with nonfunctioning AI and 46 properly matched control subjects were included in the study. After hormonal and biochemical analysis, all participants underwent transthoracic echocardiography to obtain systolic and diastolic parameters of both ventricles, in addition to atrial conduction times by tissue Doppler echocardiography. Data were analyzed with Statistical Package for the Social Sciences (SPSS, Chicago, IL, United States) statistics, version 17.0 for Windows. P < 0.05 was considered statistically significant. Results: Left ventricular (LV) mass index and LV myocardial performance index were significantly increased in AI group. Among atrial conduction times, both intra- and interatrial electromechanical delays were significantly prolonged in patients with nonfunctioning AI. Other laboratory and echocardiographic findings were similar between groups. Conclusion: Our study revealed that intra- and inter-atrial conduction times were prolonged, and LV mass index was increased in patients with nonfunctioning AI. These findings may be markers of subclinical cardiac involvement and tendency to cardiovascular complications. Close follow-up is necessary for individuals with nonfunctioning AI for their increased cardiovascular risk. Resumo Fundamento: A maioria das massas adrenais descobertas incidentalmente, denominadas incidentaloma adrenal (IA), são adenomas adrenais não funcionantes. O manejo adequado da IA ainda é um tema de debate, e por isso é necessário investigar suas morbidades associadas. Entretanto, dados referentes a alterações cardíacas morfológicas e funcionais são limitados nesse grupo. Objetivo: Neste estudo, objetivamos avaliar as características estruturais e funcionais cardíacas e as propriedades de condução atrial em pacientes com IA não funcionante. Métodos: Trinta pacientes com IA não funcionante e 46 controles adequadamente pareados foram incluídos no estudo. Após análise hormonal e bioquímica, todos os participantes foram submetidos a ecocardiograma transtorácico para obtenção de parâmetros sistólicos e diastólicos de ambos os ventrículos, além dos tempos de condução atrial pelo ecocardiograma com Doppler tecidual. Os dados foram analisados com o Statistical Package for the Social Sciences (SPSS, Chicago, IL, Estados Unidos), versão 17.0 para Windows. P < 0,05 foi considerado estatisticamente significativo. Resultados: O índice de massa do ventrículo esquerdo (VE) e o índice de desempenho miocárdico do VE foram significativamente aumentados no grupo IA. Entre os tempos de condução atrial, os atrasos eletromecânicos intra- e interatriais foram significativamente prolongados em pacientes com IA não funcionante. Outros achados laboratoriais e ecocardiográficos foram semelhantes entre os grupos. Conclusão: Nosso estudo revelou que os tempos de condução intra- e interatrial estavam prolongados e o índice de massa do VE estava aumentado em pacientes com IA não funcionante. Esses achados podem ser marcadores de envolvimento cardíaco subclínico e de tendência a complicações cardiovasculares. Um acompanhamento rigoroso é necessário para indivíduos com IA não funcionante, devido ao aumento do risco cardiovascular.

WOS: 000444683700017, PubMed ID: 30216349, Objectives The most challenging stage of cardiac resynchronization therapy (CRT) is coronary sinus cannulation (CS). The aim of this study was to compare coronary sinus cannulation techniques using electrophysiology catheters and coronary angiography catheters. Methods In this observational, retrospective and non-randomized study, 87 patients who were eligible for CRT device implantation were screened at Kahramanmaras Sutcu Imam University Hospital between March 2014 and March 2018. Seventy-two patients who met the inclusion criteria were enrolled in the study. The study population was divided into 2 groups: the first group consisted of 36 patients whose coronary sinuses were cannulated via electrophysiology (EP) catheters and the second group included 36 patients who received coronary angiography catheters for coronary sinus cannulation. Results The two groups were similar in terms of the baseline characteristics of the patients. The total fluoroscopy time was less with cannulation using coronary angiography catheters. There were no differences between the two groups in terms of the amount of contrast material and the success of the operations. Conclusions Coronary sinus catheterization using coronary angiography catheters significantly reduces fluoroscopy time in patients undergoing CRT.

Objective: Coronary artery ectasia (CAE) is defined as an angiographic enlargement of a portion of the coronary artery between 1.5 and 2 times the diameter of the adjacent normal coronary artery. It has been demonstrated that increased serum prolidase activity (SPA) is associated with increased collagen turnover. We aimed to analyze the relationship between CAE and serum SPA levels. Methods: This study used a prospective case protocol design. A total of 40 consecutive patients with isolated right CAE and normal coronary arteries (23 men, 17 women; mean age, 62.4±10.8 years) were evaluated. The control group included the same number of consecutive patients with angiographically normal coronary arteries (20 men, 20 women; mean age, 63.8±11.1 years). Clinical characteristics, laboratory results, cardiovascular risk factors, and medication use were recorded. SPA was measured using a spectrophotometer. Student’s t-test, Mann–Whitney U test, chi-square test, Pearson’s and Spearman’s correlations, logistic regression analysis, and ROC curve analysis were used for statistical analysis. Results: SPA was significantly higher in the CAE group compared with the control group (1635.2±492.0 U/L and 986.2±422.3 U/L, respectively; p
