The study suggests that “a bit of mathematics” can improve heart health

Many people employ a smartwatch to monitor their cardiovascular health, often, counting the number of steps they take during the day or registering an average daily heart rate. Now scientists offer an improved record that connects two with basic mathematics: they divide the medium daily heart rate through the average average number of steps.

The intercourse has arisen – daily heart rate or DHRP – provides insight into how effectively the heart works, According to the study Carried out by scientists from Feinberg School of Medicine at Northwestern University and published today at the Journal of the American Heart Association.

The study showed that people whose hearts work less effectively, according to this record, were more susceptible to various diseases, including type II diabetes, hypertension, heart failure, stroke, coronary atherosclerosis and myocardial infarction.

“It’s a measure of ineffectiveness,” said Zhanlin Chen, a third-year medical student at the Feinberg School of Medicine at Northwestern University and the main author of Recent Study; His co -authors are several Faculty Doctors Feinberg. “It looks like a bad heart,” he added. “You just have to do some mathematics.”

Some experts said that they perceived wisdom in DHRP as a measure. Dr. Peter Aziz, a pediatric cardiologist at Cleveland Clinic, said that it seemed that this was progress in the field of information provided by daily steps or the average heart rate itself.

“Probably more crucial for fitness cardio is what your heart does for the amount of work that he has to do,” he said. “It’s a reasonable way to measure it.”

The record does not look at the heart rate during exercise. But Dr. Aziz said that it still provided a general sense of performance, which, importantly, showed that researchers are related to the disease.

Dr. Aziz said that the size of the study added the validity of the findings. Scientists mapped Fitbit data of almost 7,000 smartwatch users compared to electronic medical records.

Mr. Chen said that a basic way to understand the value of the modern metric was to compare two hypothetical people. Both take 10,000 steps a day, but one has an average of 80 daily heart rate – in the middle of a well range – while the daily resting heart rate is 120.

The first person would have DHRP 0.008, the second 0.012. The higher the ratio, the stronger the risk of heart risk.

In the study 6,947 participants were divided into three groups based on their indicators; People with the highest level showed a stronger relationship with the disease than other participants. The study showed that the DHRPS record was also better in revealing the risk of the disease than just the number of steps or heart rate.

“We designed this metric to make it affordable and using the data we are already collecting,” said Chen. “People who want to be responsible for their own health can do some mathematics to figure it out.”
