Flagship 2: Cardiovascular diagnostics and therapeutics

Summary

Cardiovascular dysfunction (CVD) is a leading cause of death, hospital admission, and reduced quality of life, and costs approximately 1% of New Zealand’s GDP. To reduce the economic and societal costs, we need better ways to estimate and monitor key biomarkers that are not directly measurable - but that can be used to guide CVD patient management in a more reliable and personalised manner.

The overall goal of this Flagship is to develop model-based biomarkers and methods to guide care of CVD patients.
