Cardiovascular DiseasesCoronary Arteriosclerosis3 moreTo compare the effects of two intensive lipid-lowering regimens with conventional therapy on coronary atherosclerosis as assessed by arteriography.
Omega-3 Supplementation on Serum Fetuin-A Levels
Coronary Artery DiseaseBackground and aims: One of the investigated possible modulators of serum fetuin-A, associated with the risk of developing coronary artery disease (CAD), is omega-3 fatty acids (FAs). This study aims to evaluate the effects of omega-3 FA supplementation on serum fetuin-A concentration in patients with CAD. Methods: The study was carried out on 34 male volunteer patients aged 35-75 years, newly diagnosed with CAD by conventional coronary angiography. Patients with CAD were divided into the "Omega-3 Group (n:16)" and "Control Group (n:18)". Low-fat diet principles were explained to both groups at baseline. While 1.560 mg/day omega-3 FA supplementation was given to the patients in the omega-3 group for eight weeks, but not in the control group. Food intake was recorded using six-day food records.
Extremes of Coronary Artery Disease and Normality:CAD Extremes
Coronary Artery DiseaseIn the field of cardiovascular medicine, there are two differing groups of patients that remain puzzling to clinicians: patients who are not expected to have coronary artery disease (CAD) yet are diagnosed with significant CAD; and those who are have multiple risk factors for CAD but do not have CAD. Bats exhibit unique phenotypes including long lifespans and likely reduced atherosclerosis. Prior work has identified multiple molecular mechanisms of suppressing the activation of inflammasomes, causally linked to atherosclerosis. The investigators hypothesize there are different molecular markers that confer protection or increased risk for CAD, some of which may be similar to bats. Thus, the aim of this study is to identify molecular markers that contribute to or are protective against acute coronary syndrome (ACS) through analyzing the genetics, peripheral blood and atherosclerotic samples from both extreme patient groups using single-cell RNA sequencing and multi-omics approach. In addition, novel anti-atherosclerotic mechanisms and factors from bat studies will be assessed in the human samples. Identification of novel targets that prevent or cause CAD has the potential to aid in the early identification of high-risk patients and development of new therapeutics to combat this growing epidemic. To conduct this study, patients who have undergone a coronary angiogram or a CT coronary angiogram that fall into the both extremes will be recruited and blood samples will be taken for the above analysis. These will be compared to a group of controls (low risk without disease and high risk with disease).
Evaluation of PCD-CT Based Image Parameters in the Assessment and Quantification of Coronary Artery...
Coronary Artery DiseaseThe goal of this observational study is to learn about a new type of computed tomography (Photon-Counting Detector CT) in patients with coronary artery disease. The main questions it aims to answer are: How good is the image quality for the new CT How accurate are measurements in the images of the new CT Is there a relationship between measurements in the images and the management of the disease (e.g. new medication or additional investigations) Is there a relationship between measurements in the images and the results of follow-up investigations Is there a relationship between measurements in the images and the patient outcome Participants will undergo normal clinical assessment of coronary artery disease and all data from the CT scan and additional investigations will be collected. There will be no additional investigations for the purpose of the study. After 1, 2 and 5 years, participants will be asked to answer a health questionaire.
Compressive Elastic Dressing Versus TR Band
Coronary Artery DiseaseMyocardial Infarction11 moreRadial approach is widely established in cardiac diagnostic and therapeutic treatments. It has been shown to decrease bleeding, vascular problems, and mortality rates when compared to the femoral approach. It also offers better comfort to patients through early mobility and lowers hospital expenses. Previously, there were no specific devices for radial artery hemostasis. Many different types of dressings were used in various hospitals with no standardization. This raises the question of whether specific devices surpass dressings in terms of patient comfort, time required to maintain hemostasis, and vascular complications. The primary goal of this study was to examine the effectiveness of compression dressings and hemostatic wristbands on patients undergoing cardiac procedures via radial approach in terms of patient comfort, time required to maintain hemostasis, and vascular problems. The hemostatic wristband TR BandR (Terumo Corporation, Tokyo, Japan) was utilized in one group, while compressive elastic dressing, standardized as 13 threads gauze overlapped, opened, longitudinally pleated once and wrapped, making a 5-cm long cylinder, 1-cm in height, was used in the other.
Platelet Aggregation and Adenosine Levels Among Patients Taking Ticagrelor or Prasugrel
Coronary Artery DiseaseProspective, single-center, double blind, double dummy, randomized trial. Platelet function tests and adenosine levels were assessed at baseline and 15 days after taking Ticagrelor with Prasugrel placebo or Prasugrel with Ticagrelor placebo in stable patients with coronary artery disease

Administration of Mesenchymal Stem Cells in Patients With Chronic Ischemic Cardiomyopathy (MESAMI2)...
Chronic Myocardial IschemiaStem cell therapy is an emerging treatment for cardiovascular disease but the best cell type and delivery method remain to be determined. Pre-clinical studies demonstrated improvement of cardiac function by Mesenchymal stem cells (MSC) therapy in particular by their paracrine and immunosuppressive properties. Investigators initiated the MESAMI program by the bicentric pilot phase and highlighted the safety and feasibility of intramyocardial injections of MSCs from bone marrow in patients with chronic ischemic cardiomyopathy and left ventricular dysfunction, guide by the NOGA-XP system. The MESAMI program continues with the phase 2, multicenter, double-blind, randomized, placebo-controlled trial.The aim of this phase 2 study is to demonstrate a functional improvement, measuring peak VO2, at 3 months between the cell therapy group and the placebo group.
The Comparison of Strategies to PREPARE Severely CALCified Coronary Lesions Trial (PREPARE-CALC)...
Coronary Atherosclerosis Due to Severely Calcified Coronary LesionThe primary objective of this study is to evaluate the success of lesion preparation with either rotational atherectomy or cutting/scoring balloons as well as the long term effects of a hybrid sirolimus-eluting stent in an angiographically well-defined group of patients with complex calcified coronary lesions.
Colchicine in Percutaneous Coronary Intervention
Coronary Artery DiseaseAcute Coronary SyndromeInflammation in the arteries of the heart may increase the risk of cardiac death. The proposed research seeks to identify the potential beneficial role of a safe anti-inflammatory medication, colchicine, on reducing damage caused by opening up a blockage in the arteries of the heart. With its quick onset of action and excellent safety profile, colchicine may have the potential to reduce risk of major adverse events related to the heart. This research also seeks to better understand the role of neutrophils, the most common type of inflammatory white blood cell in the body, when there is damage to the heart.
