Complications
Patients usually have paroxysmal to persistent AF with risk factors to thromboembolic events, such as left atrial dilation, congestive heart failure, hypertension, diabetes, hyperlipidemia, and advanced age.
Controversy exists regarding the treatment of established embolic acute stroke in the presence of new-onset AF. Anticoagulation in this setting may cause hemorrhagic stroke. Consultation with a specialist (neurologist) is highly recommended. Novel approaches to interrupt thrombus propagation by intravascular devices are being studied.
Rapid ventricular rate and increased myocardial demand may lead to acute MI in people with coronary artery disease.[166]
Rapid ventricular rate, increased myocardial demand, and unfavorable hemodynamics may lead to acute heart failure in people with coronary artery disease, left ventricular dysfunction, and valvular pathology.[166]
