CAD-risk: Risk Stratification for Coronary Artery Disease With Type 2 Diabetic Patients
Study Details
Study Description
Brief Summary
Diabetic type 2 patients (DB2) has a higher prevalence of coronary artery disease (CAD) than non-diabetic persons. Presence of CAD results in murmurs arising from the filling of the arteries and can be detected by the CADScor System and can together with biological patient profile indicate the risk of presence of CAD in the patient. In the pilot study 100 asymptomatic DB2-patients examined with CADScor System and biomarkers will be compared with computed tomography (CT) cardiography and single-photon emission computed tomography (SPECT) for assessing if combination of patient profile (gender, age etc) combined with above measures may give rise to new improved risk scoring method for he DB2-patient.

Detailed Description
The study is intended as a pilot observational study for evaluation of a new risk scoring method, CADScor System, is relevant for assessment of CAD in the DB2-patient.
The primary end point will be to document that the hypothesis of combining the CADScor System measure with other patient profile data will increase the accuracy of the method for determination of risk of presence of CAD.
The secondary endpoint will be to show that a receiver operating characteristic curve (ROC) of > 80% for correct determination of presence of CAD will be achieved.
The further objective of the study will be to confirm the relevance of performing a large scale study with equivalent objectives.
As controls in the study will be applied CT angiography, CT-calcium and resting and drug induced CT-scintigraphy.
It is assumed that 15-20 of enrolled patients in the study will suffer from CAD.

Outcome Measures
Primary Outcome Measures
- Acoustic Cad-score [1 year]
Comparison of an non-invasive acoustic Cad-score as risk prediction for presence of coronary artery disease with control studies of CT-angiography and resting and drug induced CT scintigraphy
Secondary Outcome Measures
- The degree of presence of coronary artery disease (CAD) in Diabetic type 2 patients (DB2) patients [1 year]
Resting and drug induced perfusion test will be compared to CT Angiography for determining the degree of presence of CAD when including patient parameters characterizing the status and severity of the DB2.
