<jats:title>Background</jats:title>
<jats:p xml:lang="en">To address the need for personalized prevention, we conducted a subject¿level meta¿analysis within the framework of the Heart ¿OMics¿ in AGEing (HOMAGE) study to develop a risk prediction model for heart failure (HF) based on routinely available clinical measurements.</jats:p>

Three studies with elderly persons (Health Aging and Body Composition [Health ABC],
<jats:italic>Valutazione della PREvalenza di DIsfunzione Cardiaca asinTOmatica e di scompenso cardiaco</jats:italic>
[PREDICTOR], and Prospective Study of Pravastatin in the Elderly at Risk [PROSPER]) were included to develop the
<jats:styled-content style="fixed-case">HF</jats:styled-content>
risk function, while a fourth study (Anglo¿Scandinavian Cardiac Outcomes Trial [ASCOT]) was used as a validation cohort. Time¿to¿event analysis was conducted using the Cox proportional hazard model. Incident
<jats:styled-content style="fixed-case">HF</jats:styled-content>
was defined as
<jats:styled-content style="fixed-case">HF</jats:styled-content>
hospitalization. The Cox regression model was evaluated for its discriminatory performance (area under the receiver operating characteristic curve) and calibration (Grønnesby¿Borgan ¿

statistic). During a follow¿up of 3.5 years, 470 of 10 236 elderly persons (mean age, 74.5 years; 51.3% women) developed
<jats:styled-content style="fixed-case">HF</jats:styled-content>
. Higher age, BMI, systolic blood pressure, heart rate, serum creatinine, smoking, diabetes mellitus, history of coronary artery disease, and use of antihypertensive medication were associated with increased
<jats:styled-content style="fixed-case">HF</jats:styled-content>
risk. The area under the receiver operating characteristic curve of the model was 0.71, with a good calibration (¿

<jats:p xml:lang="en">
Simple measurements allow reliable estimation of the short¿term
<jats:styled-content style="fixed-case">HF</jats:styled-content>
risk in populations and patients. The risk model may aid in risk stratification and future

prevention strategies.
