Coronary Computed Tomographic Angiography in Intermediate-risk Chest Pain Patients
Chest PainAcute Coronary Syndrome1 moreThe aim is to determine whether a diagnostic strategy including early coronary computed tomographic angiography in intermediate-risk patients presenting to the Emergency Department with chest pain reduces the composite endpoint of death, readmission because of myocardial infarction or unstable angina requiring revascularization.
A Danish ICD-study in Patients With Coronary Artery Disease Resuscitated From Ventricular Fibrillation...
Coronary Artery DiseaseAcute Myocardial Infarction4 moreDanICD is a randomized, controlled study to with the aim to assess whether there is a benefit of ICD-implantation in patients with coronary artery disease (including acute myocardial infarction), who survive cardiac arrest due to ventricular fibrillation/sustained ventricular tachycardia and undergo revascularization and with an LVEF above 35%.
Early Detection of Coronary Artery Disease by Polygenic and Metabolic Risk Scoring
Coronary Artery DiseaseThe overall goal of this study is to develop a combined polygenic risk score (PRS) and metabolic risk score (MRS) and determine its impact on selecting community members for CCS. The trial component of this study will compare the use of these scores to motivate people to adhere to therapy, an ongoing challenge for clinicians, by providing feedback in a meaningful form to both the clinicians and the patients.
CPET in Myocardial Ischemia
Myocardial IschemiaThe investigators goal is to determine whether cardiopulmonary exercise testing (CPET) can be utilized in the diagnosis of myocardial ischemia. For the study participants the investigators will recruit patients who have been referred to myocardial perfusion PET/CT scan in Kuopio University Hospital. The participants will perform the CPET on a cycle ergometer on separate day after the perfusion scan. The investigators will compare the results of the PET/CT scan and CPET and evaluate if the possible perfusion defects detected in PET/CT correlate with the gas exchange parameters in CPET. The patients who receive invasive coronary treatment (coronary bypass surgery or percutaneous coronary intervention) will be invited to perform additional CPET ja PET/CT tests six months after the treatment. The goal will be to determine whether the recovery of myocardial perfusion can be assessed with gas exchange parameters in CPET.
PCI vs. CABG in the Treatment of Unprotected Left Main Stenosis
Coronary Artery DiseaseCoronary Artery Bypass Grafting Versus Drug Eluting Stent Percutaneous Coronary Angioplasty in the Treatment of Unprotected Left Main Stenosis. In a clinical, randomized, 5-year follow-up study to compare essential clinical outcome parameters in patients with unprotected left main (LMCA) disease, treated with coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) using drug eluting stents (DES). DES-PCI of unprotected LMCA disease is non-inferior to CABG concerning the 2-year rate of death, myocardial infarction, stroke or new revascularization and concerning the 5-year rate of death.
PET/CT* vs. Cardiac CT for Detecting Coronary Atherosclerotic Disease [*PET: Positron Emission Tomography;...
Coronary Artery DiseaseAtherosclerosis1 moreEarly detection of coronary atherosclerotic disease facilitates adequate prevention. The purpose of this study is to compare an assessment of coronary atherosclerotic disease burden by positron emission tomography / computed tomography (NaF-PET/CT) with those of conventional and ultra-high-resolution-CT (UHR-CT) in patients with suspected coronary artery disease. For this purpose, the investigators plan to include 33 patients with symptoms concerning for CAD who have been referred for cardiac CT testing.
xSPECT-based Myocardial Perfusion Scintigraphy: Consistency of Functional Values and Feasibility...
Coronary Artery DiseaseThis study is to evaluate the feasibility of myocardial Standardized Uptake Volume (SUV) assessment by means of X- (Single photon emission tomography) SPECT/Computed tomography (CT), to assess normal reference value under rest and stress in a homogeneous population without Coronary Artery Disease (CAD) and to assess the variation of absolute quantitative SUV measurements under rest and stress. The values will be evaluated in comparison with perfusion Positron Emission Tomography (PET)/CT (using 82Rb as perfusion tracer) and CT coronary angiography (CTCA) with contrast medium.).
A Non-invasive Index of Microciculatory Resistance
Coronary Microvascular DiseaseCoronary Artery DiseaseCoronary artery microvascular disease (CMVD) lacks reliable and non-invasive quantitative diagnosis methods. Improving coronary microcirculation has become one of the main goals of coronary heart disease treatment. In this study, by establishing the key influencing factors of myocardial microcirculation perfusion, an accurate three-dimensional reconstruction method of coronary artery was established, and a non-invasive coronary microcirculation resistance index (CT-IMR) calculation method based on computational fluid method mechanics was established. At the same time, a phase I single-center clinical verification and a multi-center clinical verification of the non-invasive coronary microcirculation function precision assessment system were carried out, and a non-invasive coronary microcirculation detection system and technology were established.
Role of Sugammadex as Reversal Agent in Patients Extubated Immediately After Isolated Coronary Artery...
SurgeryCoronary Artery DiseaseThe purpose of this study is to examine whether the use of Sugammadex will reduce time from reversal to extubation and improve other post extubation outcomes in Coronary artery bypass grafting patients. This study is a prospective, clinical interventional, randomized single blinded single-center design. The nurses in the cardiac intensive care unit will be blinded to treatment allocation (Group 1 or 2).

To assess the diagnostic accuracy of the A2AR profile (i.e. KD/EC50) for identifying myocardial ischemia in patients with suspected CCS compared to the gold standard inducible myocardial ischemia. To determine the best threshold value for A2AR expression for identifying significant obstructive CAD (FFR<0,8) in patients with CCS, and to estimate the diagnostic performances associated with the identified threshold To determine the best threshold value for A2AR profile (i.e. KD/EC50) for identifying myocardial ischemia (See annex 2) in patients with CCS and to estimate the diagnostic performances associated with the identified threshold.
