Among asymptomatic patients with structurally normal TTE undergoing treatment with anthracyclines or alkylating agents that develop mildly elevated BNP and/or troponin levels, would you consider referring them for cardiac MRI to evaluate for subclinical cardiotoxicity?

If TTE images are adequate and the echo is entirely normal, but BNP and/or troponin levels are mildly elevated after anthracyclines or alkylating agents, differential diagnosis includes HFPEF, ischemia, or subclinical cardiotoxicity. If Echo shows unexplained significant LVH, CMR is reasonable to ru...
