  • Capable of providing written informed consent and willing to adhere to all protocol requirements
  • Histologically confirmed HER2-positive breast cancer, as confirmed on immunohistochemistry (IHC) or fluorescence in situ hybridisation; Participants with IHC 1+ or 2+ results, also known as HER2-low cancer, are allowed to participate if they are planned for treatment with HER2-directed therapies
  • Planned for or commenced treatment with HER2-directed therapy for less than 3 months, which include monotherapy or combination therapy with any of the following agents - Trastuzumab, Pertuzumab, Trastuzumab emtansine, Trastuzumab deruxtecan, Neratinib, Lapatinib

排除标准

  • Unable to provide written informed consent
  • Unable or unwilling to adhere to all protocol requirements
  • Commenced current treatment with HER2-directed therapy for 3 months or longer
  • History of left ventricular dysfunction or heart failure with reduced ejection fraction, defined as left ventricular ejection fraction of <50% (this includes patients with left ventricular dysfunction identified on baseline screening echocardiogram or previous left ventricular dysfunction that recovered with cardioprotective medications)
  • History of left ventricular dysfunction during previous treatment with HER2-directed therapies
  • History of severe valvular heart disease
  • Poor imaging quality on baseline screening echocardiogram limiting interpretation of baseline and potentially future echocardiogram results
  • Severe uncontrolled tachyarrhythmia
  • History of ventricular tachycardia or ventricular fibrillation
  • History of permanent pacemaker or implantable cardiac defibrillator implantation
  • Prognostic factors associated with an expected survival less than 12 months as per treating clinician discretion.
