- Primary Outcome Measures
Name Time Method To determine if quantitative assessment of myocardial function with TDI is more sensitive than changes in left ventricular ejection fraction for detecting early cardiomyopathy in breast cancer patients receiving anthracycline based chemotherapy.This will be assessed by performing study procedures and monitoring be the investigators. See the timepoints below.[At four diferrent timepoints during chemotherapy treatment: pre chemotherapy, post cycle 1, post cycle 3 and 6 months post chemotherapy.];To determine if the biochemical markers Troponin I and B-type natriuretic peptide (BNP) co-relate more closely to changes in myocardial TDI velocities than they do with changes in LV ejection fraction. This will be assessed by performing study procedures and monitoring be the investigators. See the timepoints below.[At four diferrent timepoints during chemotherapy treatment: pre chemotherapy, pre cycle 2, post cylce 3 and 6 months post chemotherapy.]
- Secondary Outcome Measures
Name Time Method To determine if changes in the TDI or Troponin I and BNP are able to identify preclinical changes of cardiac function. This will be assessed by performing study procedures and monitoring be the investigators. See the timepoints below.[At four diferrent timepoints during chemotherapy treatment: pre chemotherapy, pre cycle 2, post cylce 3 and 6 months post chemotherapy.]
