Review updates aerobic exercise prescription methods in CHF to address beta-blocker interference with HR reserve.
This review provides an update on aerobic exercise prescription methods for patients with chronic heart failure on beta-blocker therapy, as these medications can interfere with heart rate reserve calculations.
Answers are grounded in this paper and cite their sources.
May inform exercise prescriptions in beta-blocked HF; leaves open need for prospective validation of updated methods.
Aerobic exercise training is a well-established nonpharmacological tool in patients with clinically stable chronic heart failure. In recent years, β-blocker therapy has become a primary pharmacologic intervention in patients with chronic heart failure. Despite the undeniable improvements in patients, the β-blocker era has aroused uncertainties about aerobic exercise intensity prescription. It is well known that aerobic exercise prescription is performed by a percentage of the patient's heart rate reserve and the use of β-blockers could interfere in this method. For this reason, the aim of this review is to provide an update about aerobic exercise prescription in patients with chronic heart failure who are using β-blockers.

Vítor Oliveira Carvalho (2012) conducted a review in chronic heart failure. Aerobic exercise prescription was evaluated. This review provides an update on aerobic exercise prescription methods for patients with chronic heart failure on beta-blocker therapy, which can interfere with heart rate reserve calculations.
