Multicenter Study Clinical TrialImpact of age, race, and sex on the ability of B-type natriuretic peptide to aid in the emergency diagnosis of heart failure: results from the Breathing Not Properly (BNP) multinational study.
B-type natriuretic peptide (BNP) is secreted from the cardiac ventricles in response to increased wall tension. ⋯ If one assumes that failing to treat cases of CHF is worse than treating negative cases, then relatively low BNP cut-points (eg, not >100 pg/mL) should be used in patients presenting to the Emergency Department with a chief complaint of dyspnea, regardless of age, sex, or ethnicity.

Resting heart rate and cause-specific death in a 16.5-year cohort study of the Japanese general population.
Several prospective studies have reported resting heart rate (HR) to be a risk factor for certain cause-specific death, together with sex- or age-specific differences in the effects of HR on death. However, there have been few prospective data from non-Western populations. ⋯ High resting HR is an independent predictor of long-term death in the Japanese general population.
