And if it's yours pulse can foresee your own life expectancy ? This is suggested by a Swedish study published in the Open Heart Journal. Men older than 50 years, whose heart is more than 75 beats per minute (bpm) at rest, often die prematurely more often.
Heart rate at rest is on average between 50 and 85 beats per minute
In a healthy adult, heart rate at rest is between 50 and 85 pulsations per minute. For the older, it is between 60 and 70 bpm. However, it depends on many other factors other than age, such as sex, weight, medication or physical fitness. The researchers wanted to know if there was a heartbeat too high could have impact about the risk of developing cardiovascular disease or premature death.
To do this, they were studying 789 men born in 1943 in Gothenburg (Sweden) in the period from 21 yr. In 1993, subjects completed a questionnaire about their way of life and health, and consumed one review a complete medical examination, including the measurement of heart rhythm at rest. This frequency was re-measured in 2003 and again in 2014.
Heart rate above 75 bpm doubles the risk of cardiovascular disease
During the study, approximately 15% It's 789 men deceased before their 71st birthday, the same percentage developed coronary heart disease, and close 28% diagnosed is a cardiovascular disease.
These results enabled researchers to make several observations. Thus, an increase in the number of heartbeats in the fifties size up risk of cardiovascular disease. In contrast, men with a stable heartbeat between 50 and 60 years of age 44% it is less likely to develop this type of illness in the next decade. The scientists also found that the heart rate was greater than 75 bpm would double the risk of heart disease, compared to a frequency of 55 bpm or less.
Monitor your heart rate number to assess your life expectancy
Several factors can explain these results. Men with a heart rate at rest above 55 bpm in 1993 were more likely to have a lifestyle sitting, from dim and be pointed out from the others. Some of them also had other risk factors for cardiovascular disease (hypertension, overweight …).
Since it is a research field of study limited For men over 50 years, she deserves to be depth, to see if the results are confirmed in the female and / or younger population. However, it shows that monitoring changes in its heart rate can be an effective way to predict the risk of cardiovascular disease in the future. And so to estimate his chances to live longer or less.
