Heart failure and atrial fibrillation: tachycardia-mediated acute decompensation.

ABSTRACT:

Aims

Tachycardia is a reversible event that may cause hemodynamic decompensation but may not necessarily cause direct damages to the myocardium. To evaluate the clinical outcomes of patients with heart failure (HF) and atrial fibrillation (AF), whose acute decompensation was tachycardia mediated.

Methods and results

The Korean Acute Heart Failure registry was a prospective registry that consecutively enrolled 5625 patients with acute HF. Patients were classified into three groups according to the rhythm and aggravating factor: (i) 3664 (65.1%) patients with sinus rhythm (SR), (ii) 1033 (18.4%) patients with AF whose decompensation was tachycardia-mediated, AF-TM (+), and (iii) N = 928 (16.5%) patients with AF whose decompensation was not tachycardia-mediated, AF-TM (-).
