Since O2 extraction by the myocyte in maximal at rest, only an increase in coronary blood flow can increase MVO2 during exercise. Therefore, if a coronary stenosis limits the maximal coronary flow, it will limit MVO2 and DP at exercise.\n\nPatients with both an exercise test and a coronary artery imaging (cardiac CT or coronary angiography) within 3 months, are included. DP increase (DP max\u002FDP at rest) is measured during a maximal, symptom-limited exercise on a cycloergometer. DP at rest is measured either before the exercise test, at the end of the recovery period or during a visit to the cardiologist in the 2 months of the test, whichever is the smallest.\n\nThe predictive power to detect a significant coronary artery stenosis is assessed by computing a Receiving Operating Characteristic (ROC) curve, its area under the curve, sensitivity, specificity, and decision thresholds.\n\nNumber expected: 100-120 Time period of data collection: 1\u002F1\u002F2019 to 3\u002F1\u002F2022","Out-patients attending Centre Hospitalier Sud Francilien's cardiology department.",[26,30],{"type":27,"name":28,"description":29,"armGroupLabels":20,"otherNames":20},"DIAGNOSTIC_TEST","Exercise test","exercise test on an exercise bike with increasing load",{"type":27,"name":31,"description":32,"armGroupLabels":20,"otherNames":20},"Cardiac CT","cardiac CT scan",[34],{"name":35,"affiliation":5,"role":36},"Olivier CHARANSONNEY, MD","PRINCIPAL_INVESTIGATOR",[38,42],{"name":35,"role":39,"phone":40,"phoneExt":20,"email":41},"CONTACT","0161697766","olivier.charansonney@chsf.fr",{"name":43,"role":39,"phone":44,"phoneExt":20,"email":45},"Caroline TOURTE","0161693730","caroline.tourte@chsf.fr",[47],{"facility":48,"status":49,"city":50,"state":51,"zip":52,"country":51,"countryCode":53,"cosmosGeoPoint":54,"geoPoint":59,"contacts":60},"CHARANSONNEY Olivier","RECRUITING","Corbeil-Essonnes","France","91106","FR",{"type":55,"coordinates":56},"Point",[57,58],2.48757,48.60603,{"lat":58,"lon":57},[61],{"name":35,"role":39,"phone":62,"phoneExt":20,"email":41},"01 61 69 77 66",{"type":64,"investigatorFullName":20,"investigatorTitle":20,"investigatorAffiliation":20,"oldNameTitle":20,"oldOrganization":20},"SPONSOR","100450049",false,"NCT05140434","Evaluation of the Benefit of Exercise Testing for the Diagnosis of Obstruction in the Coronary Arteries of the Heart","Evaluation of the Predictive Power of Double-product Increase Measured During an Exercise Test for the Prediction of Coronary Stenosis As Diagnosed by Cardiac CT Scan or Coronary Angiography.","DP-Cor-1","Inclusion Criteria:\n\n* Starting betweew 1\u002F1\u002F2019 and 3\u002F1\u002F2022\n* 18 year-old patients or older\n* Patients with both exercise testing and either Cardiac CT or coronary angiography within 3 months\n* Patients informed and not opposing to their participation to the study\n\nExclusion Criteria:\n\n* Patients unable to fully understand the information related to the study","ALL","18 Years",{"count":75,"type":76},120,"ESTIMATED","OBSERVATIONAL","The purpose of this study is to determine whether exercise testing can detect an obstruction in a coronary artery, and, thereby, can avoid performing a coronary imaging in some cases.\n\nPatients with a suspicion of coronary artery disease perform an exercise test on an exercise bike with increasing load.
