ABSTRACT
Background: Coronary artery ectasia (CAE), known for localized or diffuse excessive dilatation of the coronary artery, has an unknown etiology, but it has been reported that the underlying cause may be atherosclerosis and genetic changes that may affect the arterial lumen. MicroRNAs have been shown to have an effect in aneurysm diseases and are known to contribute to vascular development and atherosclerosis. The purpose of this study was to investigate whether they are also associated with CAE. Methods: This cross-sectional study consisted of 25 patients with CAE and 25 subjects with normal coronary arteries. Blood was collected and miRNA expression was detected using the Rotor-GeneQ real-time polymerase chain reaction cycler (Qiagen) to investigate expression levels of miR-24-1-5p, miR-34a-5p, miR-126-5p, miR-143-5p, and miR-145-5p. Results: Demographic variables of CAE (mean age 59.5 ± 1.7; 12 women) and controls (mean age 57.2 ± 2.1; 16 women) were similar. miR-126-5p (p = 0.014) and miR-145-5p (p = 0.003) levels were found to be <2-fold upregulated in CAE compared to controls; miR-143-5p also showed upregulation, but it was not significant (p = 0.078). Conversely, miR-24-1-5p (p = 0.032) levels were downregulated in CAE compared to controls. miR-34a-5p was also downregulated, but this was not considered significant (p = 0.185). Conclusions: According to our study findings, miR-126-5p, miR-145-5p, and miR-24-1-5p may be associated with CAE. These microRNAs could be of diagnostic and therapeutic significance for further studies of CAE involving abnormal angiogenesis and vascular disorders and potentially serve as useful biomarkers.

BACKGROUND: To investigate retinal and optic disk microcirculation using optical coherence tomography angiography (OCTA) in order to predict related outcomes based on the SYNergy between PCI with TAXUS and Cardiac Surgery (SYNTAX) score (SS) system in coronary artery disease patients. METHODS: 104 patients were grouped based on coronary angiography results: 32 chronic coronary syndrome (CCS) patients, 35 acute coronary syndrome (ACS) patients, and 37 healthy controls. The SS system determined atherosclerosis degree and lesion-related mortality risk, followed by scoring as SYNTAX I score (SS-I) and SYNTAX II score (SS-II). Patients were further subdivided into SS-I, SS-II percutaneous coronary intervention (PCI), and SS-II coronary artery by-pass grafting (CABG) groups. Following a thorough ophthalmological examination, an OCTA Angio Retina mode (6 × 6 mm) automatically quantified retinal and optic disk microcirculation. RESULTS: The mean ages did not differ significantly among groups (p = 0.940). The outer retinal select area varied significantly among groups, with the highest values found in ACS patients (p = 0.040). Despite non-significant differences between SS-I patients and healthy controls, the former had lower capillary plexus vessel densities in all regions and in foveal vessel density 300 µm around foveal avascular zone (FD-300) (p>0.05). Vessel densities were lowest in SS-II PCI≥28.5 patients, particularly in whole (p = 0.034) and parafoveal (p = 0.009) superficial capillary plexus, and in FD-300 (p = 0.019). Vessel densities were lowest in SS-II CABG (p = 0.020), and perifoveal (p = 0.017) deep capillary plexus, and in FD-300 (p = 0.003). The outer retina flow area increased the most in SS-II CABG≥25.1 patients (p = 0.020). CONCLUSIONS: Using OCTA, a non-invasive imaging technique, to assess retinal and optic disk microcirculation appears to have the potential to yield significant clinical results in the early diagnosis or prognosis of cardiovascular diseases.

OBJECTIVE: Informed consent forms are a contract between the patient and the doctor before the medical diagnosis and treatment. It is extremely important that the patient can read and understand such forms. The purpose of the present study was to investigate the readability levels of consent forms recommended by the Turkish Society of Cardiology used in cardiology clinics. METHODS: The number of words, syllables, letters, and characters of 20 consent forms that are used in cardiology clinics were calculated. The readability scores were calculated by using the formulas of Atesman and Bezirci-Yilmaz. RESULTS: It was found that the cardiology consent forms were readable at the 11th or 12th grade according to the Atesman Index and at the high school level according to the Bezirci-Yilmaz Index. CONCLUSION: We suggest that the informed consent forms recommended by the Turkish Society of Cardiology must be simplified from the level that requires high school education to the level that requires 6 years of education, which is the average schooling year in Turkey.

Abstract Background: Although electrical and structural remodeling has been recognized to be important in the pathophysiology of atrial fibrillation, the mechanisms underlying remodeling process are unknown. There has been increasing interest in the involvement of inflammatory molecules and adipokines released from the epicardial fat tissue in the pathophysiology of atrial fibrillation. Objectives: In our study, we aimed to investigate the relationship of atrial fibrillation with increased epicardial adipose tissue, inflammatory molecules released from this tissue and omentin. Methods: Thirty-six patients who were followed up with a diagnosis of permanent AF at the cardiology outpatient clinic 33 individuals without atrial fibrillation (controls) were included in the study. Epicardial adipose tissue thickness of patients was measured by echocardiography. Serum omentin, IL 6, IL 1 beta, TNF alpha and CRP levels were measured. Man-Whitney U test was performed for comparisons and significance was established at 5% (p<0.05). Results: Epicardial adipose tissue thickness was significantly greater in the patient group (6mm [4-5.5]) than controls (4mm [3-5.5]) (p <0.001). No significant difference was found in the concentrations of omentin or inflammatory molecules between the groups. Conclusion: No relationship was found between atrial fibrillation and serum levels or omentin or inflammatory markers. A relationship between epicardial adipose tissue thickness measured by echocardiography and atrial fibrillation was determined.

PURPOSE: Sodium glucose transporter-2 (SGLT-2) inhibitors are employed in the treatment of cardiovascular diseases such as heart failure and coronary artery disease. In the present study, we aimed to investigate how Empagliflozin in SGLT 2 inhibitors affects cardiac contraction and pump efficiency in patients who have Diabetes Mellitus (DM) without cardiovascular disease. METHODS: The conventional echocardiographic records and biochemical values ââof 62 patients who had DM without a history of cardiovascular disease were evaluated before using Empagliflozin. The myocardial mechano-energetic (MME) activity and index, and global longitudinal strain (GLS) were also calculated. After 3 months of Empagliflozin use, the tests were repeated and compared with previous data. A p < .05 was considered statistically significant. RESULTS: Left ventricular GLS and MME efficiency were found to be significantly higher after treatment (-17.71 ± 2.12, -19.15 ± .71; p < .001 and 62.14 ± 18.21, 72.24 ± 26.57; p: .019). CONCLUSION: An increase was detected in left ventricular longitudinal strain and MME efficiency after using Empagliflozin for 3 months in patients with DM. This result suggests that Empagliflozin improves left ventricular pump efficiency and contraction.

OBJECTIVE: Dietary recommendations, in addition to medications, have recently become important in the treatment of heart failure. Our study aimed to show the positive effects of both milk chocolate and dark chocolate on heart failure through endothelial functions. METHODS: Twenty patients with heart failure and reduced ejection fraction were included in the study. In this randomized, crossover study, some of the patients consumed milk chocolate and some consumed dark chocolate. We recorded the patients' 6-minute walking tests, flow- mediated dilatation values, plasma catechin, epicatechin, and N-terminal pro-brain natri- uretic peptide values before and after chocolate consumption. After 2 weeks, their chocolate consumption was changed. The same parameters were measured again. RESULTS: A significant decrease was observed in N-terminal pro-brain natriuretic peptide values after consumption of both milk chocolate (356 ± 54.2 and 310 ± 72.1 pg/mL; P = .007) and dark chocolate (341 ± 57 and 301 ± 60.1 pg/mL;P=.028). Flow-mediated dilation values increased after dark chocolate consumption (8.9 ± 3% and 14 ± 4.5%; P = .019). CONCLUSION: Chocolate consumption acutely decreases N-terminal pro-brain natriuretic pep- tide values in heart failure. Dark chocolate consumption also seems to improve endothelial functions by increasing flow-mediated dilation values.

Background and Aim: Despite the advances in oral anticoagulation with NOACs, careful patient and dose selection is required with NOAC therapy. Our study aimed to assess treatment patterns of NOACs in AF along with patients' continuity to NOAC treatments in first year, and their knowledge level of AF and NOAC treatment. Methods: ASPECT-NOAC was designed as an observational, prospective, and multicenter study. AF patients who were prescribed NOACs within last four months were recruited from 34 outpatient cardiology clinics covering all geographic regions of Turkey. Baseline data were collected initially whereas patient awareness was evaluated at 3 to 4 weeks. Final study visit was performed at 12 months. Results: In total, 991 patients were included to the study. Mean ± standard deviation of age was 69.4 ± 10.2 years and 53.0% of patients were female. Mean duration from AF diagnosis was 24.9 ± 50.9 months. Mean CHA2DS2-VASc and HAS-BLED scores were 3.1 ± 1.5 and 1.6 ± 1.1, respectively. AF disease and NOAC treatment knowledge levels were found to be 48.9 ± 23.1% and 73.0 ± 19.3%, respectively. Among reduced dose users 71.4% of patients were prescribed inappropriate reduced doses. Through the study follow-up, 32 patients (3.2%) deceased and NOAC therapy was discontinued in 74 patients (8.7%). Conclusion: AF patients who recently started NOAC treatment in Turkey were found to have variable knowledge about their disease and anticoagulation treatment. It was observed that most of the patients continued the NOAC treatment throughout the study. Reduced dosing of NOACs was common, which was associated with higher baseline risk for bleeding as well as stroke.
ABSTRACT
BACKGROUND: Takotsubo Cardiomyopathy (TC) is a rare disorder that is mostly caused by stress and is often misdiagnosed. We aimed to analyze Takotsubo Syndrome at the molecular level by using the Oxford Nanopore Minion Device and its protocol. METHODS AND RESULTS: Ten patients who were previously diagnosed with Takotsubo Syndrome (increased after decrease in ejection fraction and without critical stenosis in coronary arteries) and 10 healthy individuals in the control group were included in our project. The mean age was 53 ± 12.2 for the patient group and 52.4 ± 9.9 for the control group, and the left ventricular ejection fraction was 50.3 ± 11.5 for the patient group and 64.2 ± 2.8 for the control group (p < 0.05). Peripheral blood of patients and healthy individuals was taken and their DNA was obtained. By making long reads throughout the genome, the most studied regions responsible for ß-adrenergic signaling pathways; The gene expression level of cardiac ß-1 ADRB1 (rs1801253-ENST00000369295.4), G > C, (Gly389Arg) and cardiac ß-2 ADRB2 (rs1800888-ENSG00000169252), C > T, (Thr165Ile) adrenoceptors was investigated. As a result; no structural variation was detected leading to Takotsubo Cardiomyopathy. The results obtained from the bioinformatics analysis were also checked from the VarSome Tools and similar results were found. CONCLUSIONS: Many publications in TC susceptibility have that may lead to adrenergic pathway dysregulation, most studied adrenergic receptor genes in the similar literatures too. We searched for genetic variants in b1AR and b2AR genes in our study and however we could not find any variants in this study, we think larger numbers of cohort studies are needed.

OBJECTIVE: Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation in the coronary artery lumen of at least 1.5 times the diameter of adjacent healthy reference segments. The etiology of CAE is still unknown, but the most likely cause is atherosclerosis. The aim of this study was to evaluate several gene polymorphisms that are thought to have an effect on the development of coronary atherosclerosis and have been shown to cause thrombophilia in CAE patients. METHODS: The factor V Leiden (G1691A), factor V H1299R, prothrombin G20210A, factor XIII V34L, beta-fibrinogen-455 G>A, plasminogen activator inhibitor (PAI)-1 4G/5G, and methylenetetrahydrofolate reductase (MTHFR) C677T, and MTHFR A1298C polymorphisms were evaluated in 66 patients with CAE and 32 individuals with normal coronary arteries. RESULTS: Comparison of the CAE and control groups revealed that the clinical features and the frequency of polymorphism in the thrombophilic genes were similar in both groups. However, when heterozygous and/or homozygous polymorphism was compared between groups, it was found that there was a significantly higher finding of thrombophilic gene polymorphism in the CAE group (p=0.023). CONCLUSION: Thrombophilic gene polymorphism may be associated with the formation and clinical presentation of CAE.
