Cardiorespiratory fitness and the incidence of coronary surgery and postoperative mortality: the HUNT study.

Objectives: Low physical activity and cardiorespiratory fitness are known risk factors for coronary artery disease, but how they affect the risk of undergoing coronary artery bypass graft surgery is not established. We explored how physical activity and estimated cardiorespiratory fitness affect the risk of coronary surgery and postoperative outcome.

Methods: Participants with no history of coronary disease from the second wave of the Trøndelag Health Study (HUNT2) were cross-linked with the local heart surgery register and the Norwegian Cause of Death Registry.

Phase of care mortality analysis and failure to rescue in a Norwegian cardiothoracic unit.

. Two tools to categorize and present quality data, phase of care mortality analysis (POCMA) and failure to rescue (FTR) have been introduced in the cardiothoracic surgical environment, but not tested in Scandinavia. We aimed to investigate whether these tools could be used in a Norwegian patient population and to increase the understanding of why patients die after cardiac surgery.
