Filter by:The COMPLETE study is a single-centre, investigator-initiated study of patients with an indication for invasive coronary angiography with CCTA performed during the diagnostic evaluation. After identifying the presence of a coronary stenosis, defined as an epicardial lesion >50% stenosis on CCTA, patients eligible for the study will be invited to participate. The main aim of this trial is to assess the accuracy of coronary CT angiography to quantify total atheroma volume with intravascular ultrasound as reference. Patients will be divided into 2 sub-groups: Cohort 1: Patients with stable coronary artery disease or stabilized acute coronary syndromes with a clinical indication for invasive coronary angiography. Cohort 2: Patients previously revascularized with a metallic stent with a clinical indication for invasive coronary angiography. In both cohorts, patients should have undergone coronary CT angiography as part of the standard of care. Patients included in the study will be managed according to the standard of care for the assessment of coronary artery disease. Clinical follow-up will be collected until 3 years follow-up.
The CAD-MAP (Myocardial and Arterial Phenotype of Coronary Artery Disease) registry is initiated with the goal to describe the cardiac imaging map including epicardial coronary artery, coronary microcirculation and myocardium, and further exploring the prognostic value of multidimensional imaging biomarkers and predictive models in CAD patients.
This is a prospective, single-center, single-arm study to evaluate the feasibility and safety of the combination of Scoring-Balloon Angioplasty and Sirolimus-Eluting Balloon Angioplasty for the treatment of diffuse, small vessel coronary artery disease. The objective of the study is to demonstrate the feasibility and safety of the combination of scoring-balloon angioplasty (SBA) plus sirolimus-eluting balloon angioplasty (SEBA) for diffuse (lesion length ≥20 mm), small vessel (diameter 1.5 mm -2.75 mm) coronary disease.
Cardiovascular disease (CVD) is the leading cause of human mortality worldwide, imposing substantial societal and economic burdens. Traditionally, high-density lipoprotein (HDL) has been branded as the "beneficial" lipoprotein. The Framingham study found that for every 1mg/dl increase in HDL, the risk of coronary heart disease (CHD) was reduced by 2% in men and 3% in women. Subsequent studies further affirmed the inverse correlation between HDL and the risk of CHD. However, these findings were first challenged by Mendelian randomization studies which failed to identify a causal relationship between HDL and CHD. Moreover, randomized controlled trials demonstrated that therapeutically increasing plasma HDL concentrations did not reduce the risk of CHD events, prompting doubts about HDL's status as "good cholesterol." The relationship between HDL and CHD might be more intricate than previously believed, possibly not just mediated by the quantity of HDL but also intimately linked with its function. Several cross-sectional studies have confirmed the relationship between HDL subtypes and the severity of disease in CHD patients, yet findings are inconsistent. Conventional testing methods lack a universally accepted standard for defining or describing HDL subfractions, with issues like expensive equipment, poor repeatability, cumbersome operation, slow analysis, and low throughput. Microfluidic electrophoresis technology combines the merits of electrophoresis with microfluidic chip technology. This method facilitates efficient separation of substances in microchannels on a substrate, providing rapid and consistent results. Utilizing the latest microfluidic chip technology for HDL subfraction detection offers quick, accurate, and straightforward analysis with minimal sample volume and automation. It precisely reflects the serum concentrations of HDL subfractions HDL2b and HDL3, addressing the current pitfalls of clinical HDL subfraction analysis methods. This approach is poised to become the standard method for HDL subfraction testing. In conclusion, existing studies on the association between HDL subtypes and CHD remain inconsistent, with most having a small sample size. Our study, leveraging microfluidic chip technology for HDL subfraction detection, aims to further investigate: the prognostic value of HDL subtypes for the long-term outcomes of CHD patients, building a risk prediction model for adverse cardiovascular events that includes HDL subtypes.
The present study is testing spermidine treatment in elderly patients with coronary artery disease. The study is a randomized, double-blind, placebo-controlled, two-armed, parallel-group, single centre, clinical study.
[Purpose of the Clinical Study]:The purpose of this study is to conduct a clinical comparison of low-dose rosuvastatin plus ezetimibe combination therapy and high-dose rosuvastatin monotherapy in patients with minimal to intermediate coronary artery disease without percutaneous coronary intervention to confirm non-inferiority in the reduction of key cardiovascular events. [Hypothesis]:In patients who have not undergone percutaneous coronary intervention for minimal to moderate coronary artery disease, low-dose rosuvastatin and ezetimibe combination therapy are non-inferior in terms of reducing major cardiovascular events compared to high-dose rosuvastatin monotherapy.
Diseases of the heart and circulation are known as cardiovascular diseases, and they cause over 160,000 deaths each year. Coronary heart disease (CHD) is the most common cardiovascular disease. This is due to a build-up of fatty material, known as atherosclerosis, in the blood vessels supplying blood to the heart muscle. This can cause chest pain or if blocked, can cause a heart attack. Two of the main non-invasive tests to look for coronary heart disease are Computed Tomography Coronary Angiography (CTCA) and Stress Echocardiography (Ultrasound scan). CTCA shows the arteries and allows small amounts of disease to be seen that may not yet be causing any symptoms. However, if there's lots of disease and calcification, it becomes difficult to tell how severe it is, which means several tests may be needed. Stress Echocardiography shows if enough blood is reaching the heart muscle, so can show if there is severe disease that needs treatment. However, it can't see the arteries so doesn't showt small disease that may benefit from tablet treatment. There is not yet an effective non-invasive combined test that can give all this information in one go. Studies have shown that if there's atherosclerosis in another artery, a person is very likely to have coronary atherosclerosis as well. Carotid atherosclerosis, in the neck arteries, can be seen with ultrasound similar to stress echocardiography. So, by combining these two tests the investigators want to see if it is possible to see severe as well as small areas of disease in one test, to provide better treatment. The study will enrol 2,000 participants, who need investigation for CHD, equally randomised to CTCA or stress echocardiography with carotid ultrasound. We will follow these participants for 5 years and observe for any adverse outcomes and ask them to complete a questionnaire.
The present study is a prospective randomized clinical trial aimed to compare the therapeutic strategy of angiography-guided versus concurrent OCT/FFR-guided intervention in patients with coronary artery disease.
This is a prospective case-control single center observational non-randomized study. It is carried out to evaluate the diagnostic accuracy of functional tests with physical load under the control of a 12-channel ECG together with analysis of the parameters of volatile organic compounds of the exhaled breath, and single-channel ECG data.
The FRACTURE Trial is a prospective, non-randomized, single-arm, multicenter, interventional study in US and international centers.
