Vascular Toxicity with Cancer TherapyLearning Objectives
• To review the spectrum of cardiovascular toxicity
with Bcr-Abl Tyrosine Kinase Inhibitor (TKI) therapy
for Philadelphia chromosome-positive leukemias
• To evaluate risk prediction approaches
• To formulate risk surveillance and mitigation
strategies

- Does a normal test exclude risk,
does an abnormal test prohibit therapy?
- Which additional tests should these patients have?
- Should this be done routinely or only in a subset?
