Active clinical trials for "Coronary Artery Disease"

Centralized Pan-Algerian Survey on the undertreatment of hypercholesterolemia. The purpose of this study is to establish the proportion of patients on lipid-lowering pharmacological treatment reaching the LDL-C goals according to the Third Joint European Task Force guidelines in the survey population.

Coronary heart disease is a very common condition caused by narrowings in the blood vessel supplying the heart. the investigators are studying new tests to diagnose heart disease. In this study the investigators plan to investigate a special scan called a PET/CT (Positron emission tomography/computed tomography) and a new type of CT (Computed tomography) scan to tell us about the flow of blood to the heart muscle.

Coronary artery bypass graft surgery (CABG) is associated with postoperative respiratory depression. In this study we aimed at investigating perioperative parameters that could predict the nadir of postoperative respiratory function impairment.

The investigators are going to recruit patients who have a scheduled elective coronary angiography and going to do a dobutamin stress echography (DSE) before the coronary examination. Next to a regular 2D-DSE, the investigators will perform an 3-dimensional DSE, incl ventriculography. In the interventional part (coronary angiography), they will measure each stenosis with fractional flow-reserve (FFR)and herewith graduate its stenosis severity.

Background: Only around 20% of all patients seen in hospital with suspected Acute Coronary Syndrome will have Acute Myocardial Infarction. However, several studies indicate that patients where ACS had been excluded by conventional methods sustain a higher cardiac morbidity and mortality than the background population. Not all of these patients can be identified by traditional risk factors such as cholesterol, hypertension, and diabetes or with conventional methods such as ECG, troponin and clinical symptoms. Non-Contrast Cardiac-CT measures the amount of calcification in the coronary arteries and might be a useful addition in predicting future cardiac events in this patient group. The aim of this study is through a double-blinded study to determine whether non-contrast CT scan with calcium score can be used to identify patients at increased risk of death and cardiac event within the following 12 months after an acute admission where troponin measurements were normal. Methods: The study will investigate patients with suspected Acute Coronary syndrome who have been examined and subsequently sent home from an emergency- or cardiology department without ACS or another obvious explanation. 750 patients, age 30-70 years who are included in the study: "Identification of risk factors in non-cardiac chest pain patients" will be offered a non-contrast CT scan with calcium score within 14 days after the hospital contact. The participants will be included in a 12 months follow up, where the result of the calcium score is not revealed neither for the patient nor the investigator. After 12 months the results of the scan is compared with the rate of cardiac events. This project is a multicenter study and recruits patients from 6 emergency - and cardiology departments in the region of Southern Denmark. The study commences at September 2014 and results of this project are expected to contribute to the risk stratification of Non-cardiac chest pain patients.

Metabolic syndrome (MS) has been reported as a risk for cardiovascular events. The aim of the present cohort study is to investigate whether ACEi therapy reduces the rate of periprocedural myocardial injury (PPMI) after elective percutaneous coronary intervention (PCI) among patients with metabolic syndrome.

Chronic total occlusions (CTO) are encountered in almost one-fourth of patients undergoing coronary angiography. The presence of an untreated CTO has been related to adverse clinical prognosis, both in stable angina and acute myocardial infarction, and is often associated with persistent symptomatic angina. Depending on their symptomatic and functional status as well as anatomical complexity, CTO can be treated by optimal medical therapy only or therapy combined with coronary revascularization. The potential benefits of percutaneous coronary intervention (PCI) in CTO include symptom relief, improved left ventricular function, and potentially a survival advantage associated with success when compared with failed revascularization. Of note, marked advances in endovascular techniques and device technology have resulted in substantial improvements of procedural success rates of PCI in CTO. In spite of these advances, the vast majority of patients with CTO are still being managed medically or referred for coronary bypass surgery rather than PCI. The most common reason for deferring PCI in patients with CTO appears to be the uncertainty of predicting the procedural outcome of percutaneous revascularization. Further barriers to attempting CTO by PCI include the difficulty of gauging the time required for the procedure and the use of resources. The CT-RECTOR (Computed Tomography REgistry of Chronic Total Occlusion Revascularization) study was designed to evaluate the application of coronary computed tomography angiography (CTA) for the prediction of procedural outcome of PCI in CTO in an international patient population. The main purpose of this multicenter registry is to develop a noninvasive CTA-based prediction tool (CT-RECTOR Score) for grading CTO suitability for PCI.

To determine the ability of semi-automated plaque assessment in cardiac computed tomography angiography (CCTA) and high sensitive troponin T (hsTnT) for the risk stratification of patients at intermediate risk for coronary artery disease (CAD).

Coronary heart disease (CHD) is one of the leading causes of mortality and morbidity. PCI, as a well-proved and booming measure in CHD management, is invasive and of high cost, however the knowledge about the real-life PCI use in China is limited. Within a nation-wide and regional representative probability sample of hospitals in China, 14,000 CAG/PCI inpatient cases will be sampled randomly from 2001 to 2011. The sampled medical records will be reviewed and abstracted in the national coordinating centre, in order to evaluate the treatment pattern, outcomes, and cost for PCI, during the past decade. Basic data and innovative evidence will accelerate evidence-based clinical practice and policy making, and improve patients outcomes in future finally.

Coronary heart disease (CHD) pose a serious health threaten to population. PCI, as a well-proved and booming measure in CHD management, is invasive and of high cost, however the knowledge about the real-life PCI use in China is limited. By consecutively recruiting PCI patients in 30 geographically representative highest-rank hospitals, this study will examine various real-life factors, that may affect patients recovery after the procedure. Practical guidelines, appropriateness criteria and quality evaluative system for PCI will be established based on the findings, to improve patients outcomes in future finally.
