cad_pvb: SPECT Thallium test data set

Description

Single-photon-emission computed-tomography (SPECT) thallium is a non-invasive diagnostic test used to diagnose coronary artery disease (CAD). SPECT thallium test was performed on 2688 patients. CAD is diagnosed when stenosis exceeds 50% of the artery, as evaluated by coronary angiography (gold standard). Only 471 patients underwent the coronary angiography for verification of the CAD status. The rest of the patients were unverified (82.5%).
