One study finds that resting heart rate is not a factor in determining disease risk – NewsDio

The resting heart rate refers to the number of times the heart beats per minute (bpm), pumping the least amount of blood needed while the body remains stationary. A new study said that a deviation from the resting heart rate of the person's regular baseline is considered a cause for concern, as it indicates an underlying health condition, such as hypothyroidism and medication overdose. A high resting heart rate (RHR) is generally considered a risk factor for developing cardiovascular disease, however, another previous study said that RHR below 65 bmp could also be problematic. Only changes in individual normal RHR for three years indicated risks of heart disease, according to the study by the Huazhong University of Science and Technology, Wuhan, published in Scientific Reports last year in April. In the latest study by the Scripps Research Translational Institute, a similar conclusion was reached on fluctuating heart rate and disease risk. "For example, a thyroid problem called hyperthyroidism, or overactive thyroid, can cause rapid heart rates, while hypothyroidism can cause slower heart rates," said Dr. Michael Goyfman, director of clinical cardiology at Long Island Jewish Forest Hills from Northwell Health.

The fitbit device passively measures heart rate, activity levels and sleep duration, making it a very convenient monitoring tool. Across the country, 92,457 people were recruited for a minimum of 35 weeks, from March 2016 to February 2018. They had a heart rate tracker for at least two days a week, for approximately 20 hours per day. Age, sex, sleep duration and BMI were included in the daily HR analysis of almost 33 million HR values for an average duration of 320 days. "The average daily HR was 65 beats per minute (ppm), with a range of 40 to 109 Lpm among all individuals. The average RHR differed significantly according to age, sex, BMI and average sleep duration. Also variations were observed at the time of the year, with a minimum in July and a maximum in January For most of the subjects, the RHR remained relatively stable in the short term, but 20 percent experienced at least 1 week in which their RHR fluctuated at 10 bpm or more, the researchers said in their article published in PLOS ONE. These are some of the other findings based on several factors: Gender: RHR for men was between 50 and 80 bpm, while RHR for women was between 53 and 82 bpm. Age: HR gradually increased as people aged, however, beyond 50, the rate decreased. BMI: The average BMI corresponded with low RHR than those with high or low BMI. Sleep: People who slept for 7 to 7.5 hours every night had low HR. Season: every season, 2 bpm fluctuates. Individual RHR: People have a daily RHR that is normal for them, but may differ from the normality of another person by up to 70 bpm. In the future, the devices could help detect chronic diseases and infections. For now, researchers recognized the large amount of available data. However, the question remains how useful these data are. As technology evolves, it will be interesting to see if we can really detect some patterns in the data that offer significant diagnostic or prognostic use, "Goyfman added. Normal resting heart rates are individual for each person.
