Researchers in Norway found that the increase in heart rate during rest can be used to identify the symptoms of heart disease. Researchers examined 13,499 men and 15,826 women in Norway.
Participants were measured during the resting heart rate as much as two times: the first between 1984 and 1986 and measured again 10 years later, ie between 1995 and 1997. Participants were then monitored again for 12 years.
During the study, as many as 3038 people died. Among that number, 975 people die from heart and blood vessel disease, 388 of them due to ischemic heart disease.
Participants who increased resting heart rate of below 70 bpm at the first measurement to be above 85 bpm at the second measurement 90 percent more likely to die from ischemic heart disease than did participants that his heart rate during a break of less than 70 bpm in the two measurements.
Participants that her heart rate rose more than 15 bpm are also 50 percent more likely to die from any cause, compared to participants during breaks his heart rate remained stable. This increased risk remained significant even after other factors that could affect the results is eliminated, such as exercise and smoking habits.
"A person's heart rate at rest can be easily known at home, so it is easier to check the condition of your own health" said the researcher, Ulrik Wisloff from the Norwegian University of Science and Technology, in Trondheim as reported by LiveScience.com, Friday (2 / 12 / 2011).
The study, published in the Journal of the American Medical Association also found that the decrease in heart rate during rest did not appear to reduce the risk of death during the study participants.
"Researchers need to find out why the increase in heart rate at rest increased the risk of death from heart disease. It could be a marker of unhealthy lifestyle habits or indicate an underlying genetic predisposition for heart disease," said Dr. Christopher Cove, a cardiologist at the University of Rochester Medical Center.
