Many people use a smart watch to monitor cardiovascular health, and they are often by calculating the number of steps they take throughout their day, or recording average daily heart rate. Now, researchers propose an improved scale, combining the two using basic mathematics: I divide the average daily heart rate on the average number of daily steps.
Provides the resulting percentage – daily heart rate for each step, or DHRPS – insight into the efficiency of the heart, According to the study Researchers at the Faculty of Medicine at the University of Northwestern and published today in the Journal of the American Heart Association.
The study found that people whose hearts operate less efficiently, through this scale, were more likely to have various diseases, including type 2 diabetes, high blood pressure, heart failure, stroke, coronary atherosclerosis and myocardial infarction.
“It is a measure of lack of efficiency,” said Channel Chen, a third -year medical student at Fennberg Medical College at Northwestern University and the new study author. Its authors included several Venberg teaching staff. “You look at how bad your heart is,” he added. “You will just have to do a little mathematics.”
Some experts said they saw the wisdom of DHRPS as a scale. Dr. Peter Aziz, a cardiologist at Cleveland Clinic, said he appears to have provided information provided by daily steps or average heart rate alone.
He said: “It may be the most important thing for Cardio is what your heart does for the amount of work to do.” “This is a reasonable way to measure this.”
The scale does not look at the heart rate during exercise. But Dr. Aziz still provides a comprehensive feeling of efficiency, and more importantly, that researchers have a disease.
Dr. Aziz said that the size of the study added health to the results. Scientists have set the Fitbit data from approximately 7,000 smart watch users against electronic medical records.
Mr. Chen said that a simple way to understand the value of the new scale is comparing two virtual people. Both take 10,000 steps a day, but one has a daily heart rate of 80 years – in the middle of the healthy domain – while the daily heart rate of the other is 120.
The first person will have DHRPS of 0.008, and the second 0.012. The higher the ratio, the stronger the heart risk signals.
In the study, the 6947 participants were divided into three groups based on their lineage; Show those who have the highest stronger association with the disease than other participants. The study found that the DHRPS scale was also better in detecting the risk of disease more than a number of step or heart rates alone.
“We have designed this scale to be low cost and use the data we already collect,” said Mr. Chen. “People who want to be responsible for their health can do little mathematics to find out.”
