Unlock Better Heart Health with Just a Dash of Math: New Study Reveals Surprising Benefits

Many people use smartwatches to keep an eye on their heart health. Most track steps or average heart rate, but researchers are now suggesting a new approach: a simple calculation that combines these two metrics. The formula is straightforward: divide your average daily resting heart rate by the number of steps you take each day. This gives you a new measure called the Daily Heart Rate per Step (DHRPS).

According to a study led by researchers at the Feinberg School of Medicine at Northwestern University, the DHRPS can reveal how efficiently your heart is working. Those with higher ratios—indicating less efficient heart function—were found to be at greater risk for serious health issues, including Type II diabetes, hypertension, and heart disease.

Zhanlin Chen, a medical student and lead author of the study, explained, “It’s a measure of inefficiency. It shows how your heart is doing with the work it has to do.” All it requires is a little basic math.

Experts support the new DHRPS metric. Dr. Peter Aziz, a pediatric cardiologist at the Cleveland Clinic, emphasized that understanding how your heart performs in relation to the effort it exerts is essential. “This is a reasonable way to measure cardio fitness,” he said. Although the metric does not consider heart rates during exercise, it still provides an overview of heart efficiency.

The study analyzed Fitbit data from roughly 7,000 users, comparing it to their electronic medical records. This large sample size adds weight to its findings. Chen illustrated its usefulness by comparing two hypothetical people. Both may walk 10,000 steps daily, but one has a resting heart rate of 80, while the other’s is 120. The person with the higher heart rate would have a less favorable DHRPS, indicating a greater cardiac risk.

The study showed that the DHRPS metric was more effective at highlighting disease risk than simply looking at step counts or heart rates alone. In fact, participants were divided into three groups based on their DHRPS. Those with higher ratios faced a stronger association with health issues.

Chen sees the DHRPS as a tool for people wanting to take charge of their health. “It’s low-cost and uses data we’re already collecting,” he noted.

As awareness grows around heart health, the DHRPS could provide a simple and effective way for individuals to monitor their cardiovascular efficiency. This innovative metric not only fosters self-awareness but also encourages proactive health management.
