Many individuals rely on smartwatches to keep tabs on their cardiovascular health by tracking daily steps and average heart rate. Researchers are now championing a sophisticated metric that blends these two elements: the Daily Heart Rate Per Step (DHRPS). This is calculated by dividing one’s average daily resting heart rate by the average number of steps taken each day.
According to a study published in the Journal of the American Heart Association by Northwestern University’s Feinberg School of Medicine, DHRPS offers a deeper understanding of heart efficiency. The findings suggest that those with higher DHRPS numbers, signaling less efficient heart function, are more susceptible to illnesses such as Type II diabetes, hypertension, heart failure, and other cardiovascular diseases.
Zhanlin Chen, a third-year medical student and lead author of the study, explains, “This is a measure of inefficiency. It’s about assessing how well—or poorly—your heart performs. The math involved is minimal but reveals much about your heart’s health.”
Experts see merit in this metric. Dr. Peter Aziz, a pediatric cardiologist at the Cleveland Clinic, noted that DHRPS provides more insight than simply tracking steps or average heart rate. “What truly matters is how efficiently your heart operates given the workload,” he said, acknowledging the absence of exercise heart rate data but emphasizing the metric’s disease association.
Utilizing data from nearly 7,000 smartwatch users, the study uncovered that those with higher DHRPS had a stronger propensity for developing diseases than those with lower ratios. Ultimately, this innovative approach, designed for cost-effectiveness and ease of calculation, allows health-conscious individuals to gauge their cardiac health independently. Mr. Chen stated, “With just a bit of math, people can take charge of their health in a meaningful way.”
