Online Health Expert Medical News Flash: According to a study done by Javaid Newman, PhD and colleagues at the Norwegian University of Science and Technology, Trondheim, Norway and published in the December 21, 2001 issue of JAMA, an increase in the resting heart rate (RHR) over a 10-year period had an increased risk of death from all causes and from ischemic heart disease (IHD). The study enrolled 30,000 healthy men and women who were followed for a period of 12 years.
The researchers found that compared with participants with a RHR of less than 70 bpm at both measurements (10 years apart), participants with a RHR of less than 70 bpm at the first measurement but greater than 85 bpm at the second measurement had a 90 percent increased risk of death from IHD. Participants with RHRs between 70-85 bpm at the first measurement and greater than 85 bpm at the second measurement had an 80 percent increased risk.
There is already some preexisting evidence that a high RHR is associated with increased cardiovascular disease and death in the general population, independent of conventional risk factors like age, smoking, hypertension, dyslipidemia, alcohol intake, physical inactivity etc. But this was the first time a study was done to show how the increase in the RHR over a period of time independently impacts death from all causes and IHD. A previous study involving 129,135 postmenopausal women done in 2009 was able to establish RHR as an independent predictor for coronary events in women. Women with high RHR (more than 76 bpm) were significantly more likely to suffer a coronary event compared to women with lowest RHR ( 62 bpm or less). This correlation was strongest in the ages 50-64 years and less strong for women 65 years or over. There have been similar previous studies showing the direct correlation between high RHR and increased coronary events among men.
These studies including the one done by Dr. Newman further support for the hypothesis that RHR may be an important prognostic marker for IHD and total mortality. Information on RHR and its time-related changes which are so simple to perform and pretty easy to obtain and follow-up and may be useful in identifying asymptomatic healthy people who could benefit from measures of primary prevention to reduce coronary events and all cause mortality and promote longevity through timely interventions.
More research needs to be done how the results from this study can be extrapolated to sick individuals and whether or not decreasing RHR will result in a decrease in all cause mortality.

This is yet another study along with many others which shows the importance of low RHR and keeping it low over time. An easy way to achieve it is to join Online Health Expert's Free and revolutionary "Move Movement". I encourage everyone to learn more and live a longer and healthier life.
