Active clinical trials for "Coronary Artery Disease"

Patients with multivessel coronary disease have a compromised blood flow in the hearts own vessels, due to stenoses, and they are often treated with a coronary artery bypass grafting surgery. This is a big heart operation where the sternum (breast plate) is split and the heart is once again given a sufficient blood flow, by redirecting blood to the compromised areas through grafts. Another method for treating coronary disease is with percutaneous coronary intervention, or an endovascular approach that can re-establish blood flow to the hearts vessels by lessening the stenoses. However, bypass surgery is still the treatment of choice when there are multiple vessels in the heart with significant disease. In this trial we want to examine if a less invasive approach, called hybrid revascularization, where we combine the best of both treatments is better than the current standard. The combination is a minimally invasive bypass surgery, called MIDCAB which makes a bypass graft through a key-hole surgery for the anterior vessel on the heart, and catheter treatment of all other vessels with significant stenoses. We will compare the hybrid revascularization with the conventional treatment with a full bypass surgery through a sternotomy. Our hypothesis is that a less invasive revascularization strategy gives a better clinical outcome than the current standard with coronary artery bypass surgery through a split sternum. To test our hypothesis we will conduct a multicenter randomized clinical trial.

Breathing maneuvers, i.e. hyperventilation followed by breath-holding, have been shown to change coronary dynamics; hyperventilating narrows the coronary arteries, puts "stress" on the heart, and increases the heart rate, whereas breath-hold dilates the coronary arteries and decreases the heart rate," rest". Heart rate response to hyperventilation has been reported to have high diagnostic accuracy to rule out heart disease. The cardiac stress test, the modality of choice for the initial assessment of patients with suspected coronary artery disease(CAD), is routinely overprescribed by physicians, which exerts a financial burden on the healthcare system. Hence, developing an inexpensive, reliable, and available tool-HR response to breathing maneuvers- may avoid unnecessary referrals for cardiac stress tests by an effective differentiation of patients with CAD from healthy people. This study aims to assess the negative predictive value of the HR response to a 4-minute breathing maneuver for inducible myocardial ischemia, avoiding further stress testing as a gatekeeper.

The objective of this study is to evaluate safety and effectiveness of the SINOMED CBC coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.

This study sought to assess the diagnostic and prognostic values of metabolomics in coronary artery disease(CAD).

Introduction: Today it is necessary to emphasize that coronary heart disease is often associated with anxiety disorders. Research over the years has shown several and sometimes surprising links between coronary heart disease and mental illness, and has even suggested that both of these phenomena may actually cause each other. However, the exact nature of these links has not yet been clearly established. Methods: The study included 202 patients with coronary artery disease, of whom 42 patients were with stable angina pectoris, they participated as a control group, and 160 patients with unstable angina pectoris, who made up the main group. Among them there are 102 women and 100 men between the ages of 30 and 88. The average age was 63.75 ± 11.37 years. All study participants had blood in the morning on fasting after 8-12 hours of fasting from the cubital vein. Determination of the level of cytokines TNF-α, IL-1β, IL-4 and IL-10 in blood serum by enzyme-linked immunosorbent assay (ELISA). All participants in the study had blood drawn in the morning on fasting after 8-12 hours of fasting from the cubital vein. The level of uric acid was determined on the CYAN Start apparatus using a unified method. When examining patients with unstable angina pectoris were used: hospital anxiety and depression scale [Kozlova S.N. 2013]. And also the Spielberger-Khanin scale [Psychiatry - Hoffman A.G. 2010], developed by Spielberger Ch.D. and adapted by Yu.L. Khanin. to assess cognitive functions [Psychiatry - Gofman A.G. 2010].

With stress echo (SE) 2020 study, a new standard of practice in stress imaging was developed and disseminated: the ABCDE protocol for functional testing within and beyond CAD. ABCDE protocol was the fruit of SE 2020, and is the seed of SE 2030, which is articulated in 12 projects: 1-SE in coronary artery disease (SECAD); 2- SE in diastolic heart failure (SEDIA); 3-SE in hypertrophic cardiomyopathy (SEHCA); 4- SE post-chest radiotherapy and chemotherapy (SERA); 5- Artificial intelligence SE evaluation (AI-SEE); 6- Environmental stress echocardiography and air pollution (ESTER); 7- SE in repaired Tetralogy of Fallot (SETOF) ; 8- SE in post-COVID-19 (SECOV); 9: Recovery by stress echo of conventionally unfit donor good hearts (RESURGE); 10- SE for mitral ischemic regurgitation (SEMIR); 11- SE in valvular heart disease (SEVA); 12- SE for coronary vasospasm (SESPASM). The study aims to recruit in the next 5 years (2021-2025) ≥10 000 patients followed for ≥5 years (up to 2030) from ≥20 quality-controlled laboratories from ≥10 countries. In this COVID-19 era of sustainable health care delivery, SE2030 will provide the evidence to finally recommend SE as the optimal and versatile imaging modality for functional testing anywhere, any time and in any patient.

Coronary angiography and percutaneous coronary intervention (PCI) is often performed in patients with ischemic heart disease. The safety of PCI has improved with new devices and strategies, but complications still occur, especially during complex procedures. The objectives of this multi-center observational registry are to examine frequency of complications occuring during cardiac catheterization and PCI, examine procedural strategies utilized for complication management, and evaluate the clinical outcomes (both immediate and during follow-up.)

Multidisciplinary team-approach in order to offer personalized treatments represents the emerging mainstream in cardiovascular medicine. "Hybrid operative rooms" allow to offer selected heart-disease patients truly "tailored" operations. This study wants to evaluate the effectiveness and safety of Hybrid Procedures in cardiac patients in three subgroups of patients: Hybrid coronary revascularization strategy (coronary by-pass + PCI); Hybrid valve and coronary disease correction (combination of surgical valve replacement and PCI); Hybrid coronary and carotid artery disease treatment (combination of coronary by-pass and carotid stenting). The investigators hypothesize that morbidity might be reduced by 50% in hybrid procedures group as compared with predicted Society of Thoracic Surgery (STS) score.

Our study focuses on the question about primary cardiac rehabilitation (CR) patients with coronary heart disease are concerned about demonstrating the association between the patients' view of CR and social associated factors. In our study, all participants are invited to choose at least 1 question in 15 questions or provide their questions regarding their doubt about the CR after filling in their personal information. The selectable questions can be categorized into five titles: the content or purpose of CR, the method of CR, the advantage of CR, the adverse effect of CR, and the expenditure of CR.

The aim of this study is to examine in-depth cardiac function and morphology after short-term coronary occlusion by balloon inflation in patients with stable coronary artery disease (CAD) who undergo percutaneous coronary intervention (PCI).
