Active clinical trials for "Coronary Disease"

The PCI Suite is developed by Philips Medical Systems, a Philips Healthcare company. The proposed PCI Suite is a new software package which can be used during coronary interventions. The software package includes two sub-packages, known as StentBoost and Cardiac Roadmapping. The patient will undergo standard of care medical treatment for his or her cardiac condition. During the procedure, the physician may make angiograms for diagnosis and as reference for device navigation as part of the standard care. These angiograms will be automatically processed in PCI Suite and displayed on fluoroscopy for navigation support. In case a balloon catheter is inserted into the coronary arteries, the physician may take cine images as part of the standard care. These images can be automatically enhanced in PCI Suite. The primary objective of this prospective, mono-center, randomized clinical trial is to evaluate the amount of contrast medium used during percutaneous coronary intervention.

Observational, prospective multicentric, national study, evaluating the diagnostic and therapeutic pathways of patient with cronic coronary artery disease followed in Italian cardiology centers.

Epicardial adipose tissue (EAT) is a visceral adipose tissue that surrounds the heart and the coronary arteries. It is metabolically active, secreting pro- and anti-inflammatory mediators and cytokines. With increasing EAT volume, inflammatory activity increasing, which suggests that EAT may locally influence atherosclerosis development in the coronary artery tree. The amount of EAT is associated with cardiovascular disease risk factors as well as presence and progression of subclinical atherosclerosis. Likewise, EAT volume is increased in patient with prevalent and incident coronary artery disease manifestation. In the setting of acute coronary syndrome, EAT was found to be associated with the TIMI risk score and Syntax II score. While CT imaging of the heart is the gold standard for EAT quantification, transthoracic echocardiography allows for a quick and reliable assessment of EAT thickness, as has been used in research studies and may qualify for routine EAT assessment in clinical routine.However, currently data on how quantification of EAT in clinical routine may impact patient management is lacking. We aim to investigate, whether quantification of EAT thickness via transthoracic echocardiography enables improved risk stratification in patients presenting with acute chest pain to the emergency department.

Myocardial injury is common in patients without acute coronary syndrome, and therefore international guidelines propose a classification of patients with myocardial infarction by aetiology. This differentiates between myocardial infarction due to plaque rupture (type 1) and myocardial oxygen supply-demand imbalance (type 2) in other acute illnesses. However, these guidelines have not been widely adopted as the diagnostic criteria for type 2 myocardial infarction are not clearly defined. Patients with type 2 myocardial infarction have poor long term outcomes, with at least twice the mortality at five years compared to those with an index type 1 myocardial infarction. Despite the majority of deaths being attributable to non-cardiovascular events, the rate of future type 1 myocardial infarction or cardiovascular death is similar regardless of index classification. If this future risk is related to the presence of underlying coronary artery disease, then there may be the potential to improve outcomes through targeted investigation and secondary prevention. The investigators will undertake a systematic evaluation of the mechanism of myocardial injury and the role of coronary artery disease in 100 patients with elevated cardiac troponin concentrations where the diagnosis is likely to be type 2 myocardial infarction. These studies will help improve the assessment of patients with myocardial injury, refine the diagnostic criteria for type 2 myocardial infarction, and aid the design of future therapeutic trials.

Anabolic androgenic steroids (AASs) have been associated with coronary artery disease (CAD). The illicit use of these substances also leads to a remarkable decrease in high-density lipoprotein (HDL) plasma concentration, which could be a key factor in the atherosclerotic process. The investigators tested the functionality of HDL by cholesterol efflux and antioxidant capacity and its association with CAD in young men.

Patients with suspected or known coronary artery disease who are scheduled for clinically indicated SPECT myocardial perfusion imaging (MPI) and will receive invasive coronary angiogram are recruited to receive SPECT MBF study.

This study aims to determine whether the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) can be used as predictors of coronary heart disease (CHD) in CKD patients undergoing dialysis at Moewardi General Hospital Surakarta. It was hypothesized that NLR and PLR, which have been identified as inflammatory biomarkers, would be significantly related to increased arotid intima-media thickness (CIMT) in CKD patients undergoing dialysis. This study is an observational analytic study using a cross-sectional approach conducted at department of renal-hypertension and hemodialysis unit in Moewardi General Hospital in Surakarta, Indonesia from January to July 2022.

A total of 9269 adults who received CCTA scans for coronary disease evaluation during a general medical checkup at the Health Screening and Promotion Center in Asan Medical Center, Seoul, Korea between January 2007 and December 2011 were initially selected. All participants were provided with information about the potential benefits and risks of CCTA and made the decision to undergo the procedure at their own expense. They were also informed that their clinical and radiological data would be used for this study and gave their consent. Of these individuals, 7129 agreed to participate, and 6343 were enrolled in this CCTA registry.

To investigate the risk of major bleeding (including gastrointestinal and intracranial bleeding episodes) among new users of low-dose acetylsalicylic acid (ASA) in clinical practice

Background: Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome, which is one of the major risk factors of coronary heart disease (CHD). CHD is the most important manifestation of atherosclerosis, because of its immense morbidity and mortality. Transient elastography (TE, Fibroscan®) including the currently developed controlled attenuation parameter (CAP) is a non-invasive method for evaluation of liver fibrosis and steatosis, which is already implemented in routine care of patients with NAFLD. Hypothesis: The use of TE with CAP as screening for NAFLD might be an easy tool for risk assessment for CHD. Methods: Patients scheduled for routine coronary angiography will be screened for manifestation of NAFLD by TE including CAP, conventional ultrasound, clinical and laboratory parameters. Patients will be stratified for the presence of CHD based on the angiography results and correlation analysis with liver fat content will be performed. NFALD screening will be validated in a subgroup by MR-based measurements.
