Resting Heart Rate as Biomarker for Heart Diseases
In a large HUNT study, it is indicated that a rise in resting heart rate may indicate an increased risk of death from heart disease. The study was published in JAMA December 21, 2011 and The New York Times covered the study in an article January 3, 2012,
The HUNT study group consisted of close to 30,000 Norwegians aged 20 or older. The group was followed for ten years and measured twice. Findings indicate that people with heart rates at 85 beats per minute or more, were almost twice as likely to die of heart disease than people with resting heart rate at 70 beats per minute or less.
In an interview with The New York Times, the scientists explain how the study was performed with completely healthy subjects at both measurements. Professor Ulrik Wisloff of the Norwegian University of Science and Technology sum up their findings: “So resting heart rate is a simple, cost-free and strong biomarker that should be monitored regularly.”
