[Heart rate and mortality]
1Hôpital Broussais, Paris.
Insights
Increased heart rate is an independent marker for cardiovascular mortality in men and overall mortality in women. Further research is needed to determine if reducing heart rate pharmacologically can decrease mortality.
Area of Science:
- Cardiology
- Epidemiology
- Preventive Medicine
Context:
- The relationship between heart rate and cardiovascular outcomes is a significant area of research.
- Previous studies, such as the Framingham study, have indicated an association between elevated heart rate and cardiovascular events.
- Understanding the independent role of heart rate is crucial for risk stratification.
Purpose:
- To investigate whether an increased heart rate serves as an independent marker or a risk factor for cardiovascular morbidity and mortality.
- To analyze the correlation between heart rate and overall, cardiovascular, and non-cardiovascular mortality in a large cohort.
Summary:
- A large-scale French study of 20,000 patients found that heart rate is an independent marker of mortality.
- Increased heart rate correlated with overall mortality in women and both cardiovascular and non-cardiovascular mortality in men.
- The study highlights heart rate as a significant predictor irrespective of other known risk factors.
Impact:
- This research identifies increased heart rate as a critical, independent predictor of mortality, particularly cardiovascular mortality.
- Findings may influence clinical guidelines for cardiovascular risk assessment and management.
- Further investigation into the potential benefits of heart rate-lowering therapies on mortality is warranted.
Abstract:
Is increased heart rate a marker or a risk factor of cardiovascular morbidity and mortality? Several studies, including the Framingham study, have reported an association. In a large-scale French study, conducted in the Centre d'Investigations Préventives et Cliniques of Paris, based on a cohort of 20,000 male and female patients, heart rate was found to be a marker independent of the other risk factors and its increase was correlated with that of overall mortality in women, and cardiovascular and non-cardiovascular mortality in men. It remains to be seen whether pharmacological reduction of heart rate decreases mortality.
