Heart Failure

Acute Heart Failure Management

Traditional heart metrics do not directly quantify heart function and therefore make it difficult for physicians to see the individual effectiveness of acute heart failure medications on the heart. This complicates physicians' ability to manage and optimize treatment, as patients may be taking up to 8-11 different drugs with potentially interacting effects.[1]

MyoStrain® provides the sensitivity and quantitative accuracy to help physicians see how the heart responds to various treatments. This may allow physicians to select and dose therapy on an individual basis and focus on reducing re-hospitalizations and medications to ultimately improve patient quality of life.[2]

Multiparametric Early Detection and Prediction of Cardiotoxicity Using Myocardial Strain, T1 and T2 Mapping, and Biochemical Markers: A Longitudinal Cardiac Resonance Imaging Study During 2 Years of Follow-Up
This publication features key outcome data from the PREFECT study demonstrating MyoStrain's ability to help clinicians detect and predict early cardiotoxicity in patients undergoing cancer therapy. These findings highlight MyoStrain as an accurate and sensitive assessment that may enable cardio-oncologists to implement cardio-protective strategies for cancer patients.

Feasibility of fast cardiovascular magnetic resonance strain imaging in patients presenting with acute chest pain
This study indicates that in patients presenting with acute chest pain and inconclusive initial clinical screening, MyoStrain can be used to rule out obstructive coronary artery disease. These results show that MyoStrain may serve as a fast and accurate diagnostic tool that could be integrated into clinical workflows.

Myocardial deformation assessed among heart failure entities by cardiovascular magnetic resonance imaging
MyoStrain revealed that the LV septum is the location affected most, with reduced values visible in HFpEF and further reductions in HFmrEF and HFrEF where traditional CMR did not detect. This may hold significant socioeconomic implications, possibly aiding the identification of millions of presumable healthy individuals at risk for heart failure, who could benefit from early risk control and treatment.
