Why the study?
Does a resting heart rate ≥66 beats/min correlate with altered anthropometric, metabolic, and hemodynamic parameters in subjects aged 80 years and over?
Does a resting heart rate ≥66 beats/min correlate with altered anthropometric, metabolic, and hemodynamic parameters in subjects aged 80 years and over?
In individuals aged 80 and over, a resting heart rate ≥66 beats/min is associated with higher diastolic blood pressure, glucose, and total cholesterol, and lower pulse pressure.

Higher RHR links to elevated DBP and metabolic markers in octogenarians; leaves open causal and prognostic validation.
This study examined the relationship between resting heart rate (RHRr) and anthropometric, metabolic and hemodynamic parameters in subjects aged 80 years and over. One hundred thirteen individuals were divided into two groups (RHR:<66 beats/min and ≥66 beats/min). Anthropometric parameters (weight, height, body mass index and waist circumference (WC) were measured. Hemodynamic parameters (systolic (SBP) and diastolic (DBP) pressure) were measured and pulse pressures (PP) were obtained. Metabolic parameters were fasting blood glucose, triglycerides and total cholesterol. In elderly aged 80 and over, RHR influenced the changes observed in DBP, PP and triglycerides. Additionally, subjects with RHR≥66 beats/min had higher DBP, glucose, total cholesterol and lower PP as compared with elderly with RHR<66 beats/min. Men demonstrated greater weight, height, and WC than women while women had higher percentage of body fat, trunk fat, and higher total cholesterol. Thus, subjects with 80 years old and over who present RHR≥66 have higher DBP and lower PP and heart rate variability compared with the elderly with RHR<66.
