Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes.

Acute coronary syndrome (ACS) is an urgent clinical condition of cardiovascular diseases. The present study evaluated the predictive efficacy of the hemoglobin to serum creatinine ratio (Hgb/Cr) on long-term mortality in patients with ACS. The ratio, representing the proportion of the 2 values, is cheap, practical, and very easy to calculate at the bedside.

Background: Prosthetic valve thrombosis (PVT) is one of the life-threatening complications of prosthetic heart valve replacement. Due to the lack of randomized controlled trials, the optimal treatment of PVT remains controversial between thrombolytic therapy (TT) and surgery.

Objectives: This study aimed to prospectively evaluate the outcomes of TT and surgery as the first-line treatment strategy in patients with obstructive PVT.

Objective: In this study, we aimed to analyze the TURKMI registry to identify the factors associated with delays from symptom onset to treatment that would be the focus of improvement efforts in patients with acute myocardial infarction (AMI) in Turkey.

Methods: The TURKMI study is a nation-wide registry that was conducted in 50 centers capable of 24/7 primary percutaneous coronary intervention (PCI). All consecutive patients (n=1930) with AMI admitted to coronary care units within 48 hours of symptom onset were prospectively enrolled during a predefined 2-week period between November 1, 2018, and November 16, 2018.

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.

Objective: This prospective study aimed to investigate the myocardial energy metabolism in severe mitral regurgitation (MR) and explore its effect on postoperative differentiation of ejection fraction (EF).

Methods: A total of 85 patients with severe MR were prospectively enrolled from October 2018 to June 2019. During the study period, a total of 50 patients underwent mitral valve surgery and 49 patients were finally enrolled due to 1 missing data.

Objective: Despite recommendations from heart failure guidelines on the use of pharmacologic and device therapy in patients with heart failure with reduced ejection fraction (HFrEF), important inconsistencies in guideline adherence persist in practice. The aim of this study was to assess adherence to guideline-directed medical and device therapy for the treatment of patients with chronic HFrEF (left ventricular ejection fraction ≤40%).

Methods: The Adherence to guideline-directed medical and device Therapy in outpAtients with HFrEF (ATA) study is a prospective, multicenter, observational study conducted in 24 centers from January 2019 to June 2019.

Mechanical prosthetic heart valves (MPHVs) are highly thrombogenic, and a pregnancy-induced procoagulant status increases the risk of MPHV thrombosis. Despite numerous case reports, 2 major registries and meta-analyses/systematic reviews, optimal anticoagulation therapy during pregnancy remains controversial. The goal of this study was to evaluate different anticoagulation regimens in pregnant patients with MPHVs.

Objective: Since visual estimation of the extent of vessel stenosis may vary between operators, we aimed in this study to investigate both inter-observer variability and consistency between the estimation of an operator and quantitative coronary analysis (QCA) measurements.

Methods: A total of 147 elective percutaneous coronary intervention patients with 155 lesions between them were consecutively enrolled in the study. These patients were evaluated for visual estimation of lesion severity by three operators.

Coronary thromboembolism (CE) is a rare cause of prosthetic valve derived complications. This study investigates the diagnosis and treatment strategies for non-ST elevation acute coronary syndrome (NSTEACS) in patients with prosthetic heart valves. Forty-eight NSTEACS patients with prosthetic heart valves (mitral:27; aortic:14; mitral+aortic:7) were included in this study.

Background And Aim Of The Study: Protein Z (PZ) is a vitamin K-dependent factor that is synthesized mainly by the liver. It acts as an activator of serpin, the protein Z-dependent inhibitor (ZPI), which inhibits factor Xa. The potential role of alterations in protein Z and/or ZPI levels in the pathogenesis of thrombotic and/or hemorrhagic diseases has been previously investigated, but results have been conflicting.

Objective This study aimed to evaluate the safety and the efficacy of primary stenting to treat Trans-Atlantic Inter-Society Consensus II (TASC) D femoropopliteal lesions. Background Advances in wire, balloon and stent design have been reported to improve the durability of stenting of longer femoropopliteal lesions. Methods A total of 57 limbs of 53 patients with Rutherford stage 3 to 6 due to TASC D femoropopliteal lesions were treated with a self-expanding nitinol stent in a prospective, single-centre, observational study.

Background:: According to common belief, most myocardial infarctions (MIs) are due to the rupture of nonsevere, vulnerable plaques with < 70% obstruction. Data from recent trials challenge this belief, suggesting that the risk of coronary occlusion is, in fact, much higher after severe stenosis. The aim of this study was to investigate whether or not acute ST-elevation MIs result from high-grade stenoses by evaluating the presence of coronary collateral circulation (CCC).

This case report presents a case with septal occluder device thrombosis which was successfully treated with low dose longer duration of thrombolytic application. Our case showed that the thrombolytic strategy with the lower dose and the longer duration might be a valuable alternative treatment option for the septal occluder thrombosis which is anticoagulation-resistant. This strategy might obviate the need for surgery.

Background And Aim Of The Study: Prosthetic valve dysfunction (PVD) due to pannus formation is considered to occur due to a bioreaction to prosthetic material. The p53 gene plays a critical role in apoptosis and cell proliferation. p53 Arg72Pro polymorphism has been found to be associated with coronary stent restenosis, but has not yet been studied in prosthetic heart valve dysfunction.
