Abstract: A cardiovascular monitoring platform receives one or more signals collected for a user of the measurement device during a time period. The cardiovascular monitoring platform extracts measurements for a plurality of biomarkers based on the one or more signals collected for the user, wherein each biomarker characterizes an aspect of cardiovascular health of the user. The cardiovascular monitoring platform applies a heart function model to the one or more signals collected by the measurement device and the plurality of biomarkers. The heart function model outputs a heart function index that characterizes a likelihood whether the user will experience a heart failure event during a future time period. The cardiovascular monitoring platform generates an alert based on the heart function index. The alert comprises a risk state of the user determined based on a comparison of the heart function index to a threshold.
