In patients with chest pain and/or shortness of breath coronary artery disease (CAD) is suspected depending on the pattern of symptoms and the electrocardiogram (ECG). Coronary angiography is the method of choice to verify this suspicion. If the patient coronary arteries on coronary angiography are totally normal or unobstructed, one can only speculate if the patients' discomfort is from the heart or not. A possibility to get further information about the healthiness of the coronary arteries is the acetylcholine test (ACH-test). When injecting this natural, body produced-substance into the coronary arteries one can test if the vessels develop coronary spasm which can be the reason for the patient's symptoms. The investigators therefore use this test in this study to look for coronary spasm in patients with suspected CAD but normal/unobstructed coronary arteries. In case of a positive test, the patient profits from having found a cause for his/her symptoms making treatment with special tablets possible. Furthermore, the investigators want to analyze blood samples of every patient to look for signs of inflammation, vasoconstriction and genetic variants that seem to be linked with coronary spasms. On the basis of these results the ACH-test could probably be avoided in the future.
The investigators' rationale was to evaluate whether a 64-slice CT scanner allows accurate measurement of computed tomographic changes in coronary artery flow profiles and whether CT flow measurements are suitable for classifying the significance and hemodynamic relevance of a stenosis and thereby supplement as a functional parameter for morphological stenosis analysis.
The COMPETE study is a prospective,randomized,two-arm multi-center clinical trial comparing two commercially available coronary stents: Chrono Carbostent Carbofilm™ Coated vs Driver/Micro-Driver Coronary Stent System. In this study, 204 subjects will be included (2:1 randomization Chrono:Driver/Micro Driver) in 6 Italian sites.
The main objective of this study is to compare the time from randomization to the first recurrence of any ventricular tachycardia (VT) in patients undergoing VT ablation (for stable VTs) and substrate ablation (for unstable VTs) after an initial episode of stable VT and patients not undergoing ablation, with both groups under the protection of an ICD.
The aim of this study is to determine the effects of extreme fitness in women. The incidence of coronary artery disease observed via multislice computed tomography (MSCT) angiogram will be compared with age and risk-matched controls from both sedentary and fitness activity groups who have never been significant runners. Life style, training volume and risk factors will be assessed.
The aim of this prospective study is to investigate the prevalence of coronary artery disease using computed tomography with family history of premature coronary heart disease
The purpose of this study is to evaluate the effects of an intensive Cardiac rehabilitation program on glucose metabolism of non-diabetic coronary artery disease patients.
The purpose of the investigation is to verify the efficiency of the HyperQ™ system in detecting exercise induced ischemia, with higher specificity and sensitivity than conventional ECG Stress testing. The study will be carried out by applying the HyperQ™ system during cycle ergometer stress testing in patients who are referred for angiography at the Department of Cardiology, Essen University Hospital, Essen, Germany. The HyperQ™ results will then be compared to the standard ECG stress test results using the angiography results as the gold standard. The study will be considered successful if analysis of the HyperQ provides a statistically significant improvement over the diagnostic accuracy of conventional ECG stress testing analysis.
The aim of this prospective study is to investigate the prevalence of endothelial dysfunction in subjects with family history of premature coronary heart disease. At the same time, the effect of atorvastatin in treating subclinical endothelial dysfunction in those patients will be evaluated.
