Serial Biomarker Testing and Cardiovascular Risk Stratification (ACHILLES)

The goal of this observational study is to learn how blood levels of biomarkers, e.g. hsCRP and Lp(a) - two markers linked to heart disease risk - change over time in patients who have had these levels tested more than once. The main questions it aims to answer are: How often does a high result on a first test return to normal on a later test? Do patients whose levels stay high across repeated tests have a higher risk of death than patients whose high level was only temporary
