Heart Failure Burden and Heart Failure Risk in the General Population in Norway: "The HUNT for Heart Failure" Risk Score

Explore which clinical risk factors or patient characteristics in a general population that are associated with increased risk for heart failure events and combine these into a new population-based heart failure risk score ("The HUNT for heart failure risk score") for predicting heart failure risk

Validate the newly developed heart failure risk score internally in the HUNT2 database

Compare the predictive ability of the new heart failure risk score with established heart failure risk scores (the ABC Health HF risk score, the Framingham HF risk score) and an established Norwegian cardiovascular risk score (NORRISK 2)

Estimate the prevalence of likely ("undiagnosed") heart failure , i.e., patients at high risk of HF, in a general population by using both the established heart failure risk scores and the newly developed heart failure risk score, and compare the heart failure event rate between those at high risk of heart failure and those with established heart failure.
