 Summary: 
 TRUST-ACE will compare a simplified echocardiographic protocol focusing on ventricular
function with the guideline recommended comprehensive echocardiographic examination using
a randomised design in follow-up of breast-cancer patients with respect to identification
of cancer treatment related cardiac dysfunction (CTRCD).
Secondly, the study will evaluate whether novel tools used to improve standardization of
recordings as well as automated measurements of central measurements, e.g. ejection
fraction (EF) and global longitudinal strain (GLS) can improve the precision of
echocardiography in daily clinical practice. 
 Detailed description: 
 Cancer treatment related cardiac dysfunction (CTRCD) is a well-known complication to
cancer treatment with implication both with respect to treatment and prognosis of the
cancer as well as heart.
CTRCD, often named cardiotoxicity, usually refers to myocardial dysfunction and heart
failure developing after administration of potentially cardiotoxic therapy. By precise
diagnostics, adequate treatment can be started early to prevent heart failure and
unnecessary discontinuation of the potential life-saving cancer treatment may be avoided.
However, guideline advocated analyses of cardiac function (EF and GLS) by
echocardiography are time consuming and many operators base their semi-quantitative
estimates on visual assessment. Furthermore, test-retest variability for both EF and GLS
are significant and may exceed the guideline recommended cut-offs for identification of
cancer therapy-related cardiovascular toxicity.
The study will compare a simplified echocardiographic protocol focusing on ventricular
function with the guideline recommended comprehensive echocardiographic examination using
a randomized design. The study will also evaluate if novel tools for improved
standardization of recordings and automated measurements of relevant measurements as
ejection fraction (EF) and global longitudinal strain (GLS) can improve the diagnostic
precision.
Breast cancer patients referred for follow-up at the echocardiography will be included.
Patients will be randomized 1:1 to A) examinations with two- and three-dimensional
echocardiography including all central measures of cardiac size and function measured by
sonographers as recommended by the European guidelines and as clinical practice or B)
echocardiographic examinations focusing on the ventricles.
Subpopulations will undergo additional testing with serial echocardiographic examinations
by four operators on the same day with and without use of novel tools for improved
standardization of recordings and automated measurements.
