Key result
Cardiac fluoroscopy for coronary calcification was highly specific for significant coronary artery disease, with 97% of patients with detected calcification having ≧70% angiographic stenosis.
Why the study?
Does cardiac fluoroscopy accurately detect significant coronary artery disease in patients with proven or suspected coronary artery disease?
Population
360 patients with proven or suspected coronary artery disease undergoing coronary arteriography

Does cardiac fluoroscopy accurately detect significant coronary artery disease in patients with proven or suspected coronary artery disease?
Cardiac fluoroscopy is a highly specific, noninvasive, and inexpensive screening tool for detecting significant coronary artery disease.
Bartel et al. (1974) conducted a cross-sectional in Proven or suspected coronary artery disease (n=360). Cardiac fluoroscopy vs. Coronary arteriography was evaluated on Significant coronary disease angiographically (≧ 70% stenosis) in patients with coronary calcification. Cardiac fluoroscopy for coronary calcification was highly specific for significant coronary artery disease, with 97% of patients with detected calcification having ≧70% angiographic stenosis.
