The Heinz Nixdorf Recall Study

The Heinz Nixdorf Recall Study is a population-based study that aims to improve the prediction of cardiovascular events by integrating new imaging and non-imaging modalities in risk assessment. One focus of the study is the evaluation of the quantification of subclinical coronary artery calcifications (coronary artery calcification, CAC) as a prognostic factor in predicting cardiac events. Primary endpoints are myocardial infarction and sudden cardiac death. The study was initiated in the late 1990s and enrolled a total of 4,814 participants aged 45-75 years between December 2000 and August 2003. A 5-year follow-up examination took place between 2006 and 2008. Currently, the 10-year follow-up is under way and is estimated to be finished in July 2013. Extending the original aims of the study, serial CAC measurements will allow the characterization of the natural history of CAC dynamics, the identification of its determinants and an understanding of the impact of CAC progression on the primary endpoints. The Heinz Nixdorf Recall Study will significantly extend our knowledge about new modalities in the prediction of cardiac events.
