Key result
Elevated resting heart rate is a significant independent predictor of all-cause mortality and cardiovascular disease risk in both healthy populations and patients with cardiovascular disease.
Why the study?
Does elevated resting heart rate increase the risk of cardiovascular mortality and morbidity in various populations?
Does elevated resting heart rate increase the risk of cardiovascular mortality and morbidity in various populations?
Elevated resting heart rate is an emerging, independent cardiovascular risk factor that predicts all-cause and cardiovascular mortality across various populations.
Supports risk stratification; leaves open whether lowering heart rate improves outcomes.
The development of cardiovascular disease (CVD) is usually caused by multiple risk factors, which interact to produce an individuals total CVD risk. Therefore the guidelines on the prevention of CVD recommend the preventive measures be based on individuals levels of total CVD risk so that the most intensive risk factor management can be directed towards those at highest risk. Elevated resting heart rate is a known independent cardiovascular risk factor but is not included in any risk estimating system-Coronary risk chart or SCORE(Systematic Coronary Risk Evaluation).which are used for estimation of individuals 10 year risk of a CVD event based on gender, age, total cholesterol, smoking status and systolic blood pressure. The findings several epidemiological studies showed an association between elevated heart rate an increased risk of allcause mortality and morbidity in general population, hypertensives, diabetics and those with CAD.

Kauser et al. (2012) conducted a review in Cardiovascular disease. Resting heart rate was evaluated on All-cause mortality and cardiovascular disease risk. Elevated resting heart rate is a significant independent predictor of all-cause mortality and cardiovascular disease risk in both healthy populations and patients with cardiovascular disease.
