[Baroreflex activation therapy : Indication and evidence in resistant hypertension and heart failure].

Baroreflex activation therapy (BAT) is a sympathoinhibitory procedure for treatment of therapy-resistant hypertension (rsHTN) and severe heart failure with reduced ejection fraction (HFrEF) that been available for several years. The double-blind, randomized Rheos Pivotal Trial demonstrated a blood pressure lowering effect in patients with rsHTN for the first-generation BAT device. A smaller randomized study in heart failure showed that the Barostim Neo system is safe and can improve heart failure symptoms and decrease neuroendocrine activation. However, for this unilateral system, which is currently in clinical use, no data from large randomized trials exist. Despite existing data for BAT in rsHTN and HFrEF, large randomized trials, showing reduction of blood pressure and cardiovascular events are still lacking. Therefore, BAT's efficacy and safety cannot be conclusively assessed.
