AbstractAim: To study the elevated resting heart rate (RHR) represents a separate risk factor for mortality or only a sign of physical fitness.
Material and methods: The sample size for this research was 410 males. All men were given a clinical examination by a doctor (FG) that included a discussion of their responses to a questionnaire and a test of their aerobic capacity (VO2Max) on a bicycle ergometer. Heart rate and labour load data from a bicycle ergometer were used to calculate estimates of physical fitness using the strand nomogram. Using a manometer created by the London School of Hygiene and Tropical Medicine, BP was taken on the right arm of sitting subjects after at least 10 minutes of rest. The survey's questions on hypertension care led to the collection of useful data.
Results: An elevated resting heart rate has been linked to decreased fitness, hypertension, total cholesterol, triglyceride, and body mass index. Everyone got along, regardless of age or status. Smoking prevalence was greater among participants with lower resting heart rates than among those with higher resting heart rates. The VO2Max and HR at rest correlated extremely significantly (R=0.29, p0.001). Higher fitness levels were associated with decreased resting heart rates. Using heart rate as a continuous variable in an adjusted model, we find that for every 10 bpm beyond 60, the chance of death rises by 16%. Resting heart rate, smoking, and mortality all interacted to a nearly statistically significant degree. Resting heart rate was included as a continuous variable in the final model, and an increase of 10 beats per minute was associated with a 25% increase in risk for smokers and a 15% increase in risk for non-smokers.
Conclusion: Resting heart rate was shown to be an independent risk factor for death in this research of 410 healthy middle-aged and older people, regardless of physical fitness (VO2Max) as measured by a bicycle ergometer, recreational physical activity, or other traditional risk factors.
