Valvular atrial fibrillation treatment

Persistent AF: Episodes of AF that last more than 7 days and may require either pharmacologic or electrical intervention to terminate.The pulmonary veins appear to be the most frequent source of these automatic foci, but other foci have been demonstrated in several areas throughout the atria.Coronary artery disease infrequently leads directly to atrial ischemia and AF.Hyperthyroidism, diabetes, and pheochromocytoma have been associated with AF.

Atrial Fibrillation treatment with food, herbs and natural

Persistent AF with an uncontrolled, rapid ventricular heart rate response can cause a dilated cardiomyopathy and can lead to electrical remodeling in the atria (atrial cardiomyopathy).Long-standing persistent AF: AF that has persisted for more than 12 months, either because cardioversion has failed or because cardioversion has not been attempted.Structural changes of atrial myocardium due to sustained atrial fibrillation in the goat.Unstable patients requiring immediate direct current (DC) cardioversion include the following.Piccini JP, Hasselblad V, Peterson ED, Washam JB, Califf RM, Kong DF.

Patients can also have AF as an arrhythmia secondary to cardiac disease that affects the atria (eg, congestive heart failure, hypertensive heart disease, rheumatic heart disease, coronary artery disease).A meta-analysis pooled data from 43 studies and more than 278,800 patients.

Therapy, such as drugs or atrioventricular nodal modification and permanent pacemaker implantation, to control the ventricular rate can improve left ventricular function and improve quality-of-life scores.DS 2 -VASc score showed higher discrimination for predicting stroke than the model with the CHADS 2.Mortality and readmission of patients with heart failure, atrial fibrillation, or coronary artery disease undergoing noncardiac surgery: an analysis of 38 047 patients.
