Kato T, et al. - Among 143 consecutive patients 85 years or older with known or suspected coronary artery disease, researchers assessed the risk of all-cause mortality in relation to abnormal findings of cardiac scintigraphy. The participants underwent stress scintigraphy under adenosine or an exercise test and a ^99mTechnetium-labeled tracer or thallium 201 (²⁰¹Tl), dual tracer rest scintigraphy using ²⁰¹Tl and ¹²³I-β-methyl iodophenyl pentadecanoic acid (¹²³I-BMIPP), or ¹²³I-BMIPP single tracer scintigraphy. The probability of having undergone previous coronary angiography and having reduced ejection fraction was more in patients in the abnormal findings group (N  =  62) vs those in the normal findings group (N  =  81). Findings revealed an increased risk for death, even for patients 85 years or older, in relation to abnormal myocardial scintigraphy findings.
