A new study has revealed that a higher resting heart rate is linked to increased risk of death from all causes, even for those people who are not suffering from heart diseases.
"Results from this meta-analysis suggest the risk of all-cause and cardiovascular mortality increased by nine percent for every 10 beats/minute increment of resting heart rate", Zhang said. Compared with 45 beats a minute, the risk of death from any case increased linearly with increasing resting heart rate.
Though the findings are significant, the absolute risk is still small.
Still, particularly if you have other risk factors for heart and other health problems, seeing a doctor isn't a bad idea, Dr. Schussler said.
For the average adult, a normal resting heart rate is between 60 and 100 beats per minute.
"The risk of all-cause mortality increased significantly with increasing resting heart rate, but a significantly increased risk of cardiovascular mortality was observed at 90 beats/minute", the researcher added. In addition, this study does not prove the heart rate has actually caused any premature deaths. The same change also increases mortality risk from cardiovascular disease by eight percent.
Man Arrested After Threatening Manhattan Apple Store With Samurai Sword
As seen in the below photo from the Twitter account of Keith Davis, cops have the man on the ground and the sword in their hands. The man brandished the weapon on a staircase after entering the shop in Manhattan, New York, on Friday at about 4pm local time.
The authors note the limitation that various factors can affect measurement of resting heart rate and that nighttime heart rate could be a better risk predictor.
"Our results highlight that people should pay more attention to their resting heart rate for their health, and also indicate the potential importance of physical activity to lower resting heart rate".
People can find their pulse in places where an artery passes close to the skin, such as the wrist or neck.
It's known as resting heart rate, as long as the person has been resting for at least five minutes before checking their pulse.
This study was published online November the 23d in the Canadian Medical Association Journal.
