Key result
Myocardial viability assessment using nuclear medicine and other imaging modalities requires careful clinical interpretation based on the percentage of affected myocardium and coronary lesion topography.
Why the study?
Although assessing myocardial viability is common practice, diagnostic results are often questioned and nuclear medicine reports require interpretation in clinical and pathophysiological context.
Myocardial viability assessment requires interpreting imaging results within a clinical context, considering the percentage of affected myocardium and coronary lesion topography to guide revascularization decisions.
Nuclear viability reports require clinical context; review extends method explanations but leaves standardization open.
Although assessing myocardial viability is a common cardiology practice, many physicians question the results of diagnostic methods. Nuclear medicine plays an important role in viability studies, but the reports require interpretation in a clinical and pathophysiological context. this article was aimed at reviewing the origin and evolution of myocardial viability. Here we present diagnostic methods by emphasizing nuclear medicine and provide a functional explanation of each test type using example images. We also propose how to act in these cases based on clinic examination findings, the percentage of affected myocardium, and coronary lesion topography (proximal or distal).
