Is a left anterior fascicular block serious?

Left anterior fascicular block (LAFB) is considered a failure or delay of conduction in the left anterior fascicle. Despite the fact that little is known about the long-term prognosis associated with LAFB, it has generally been thought of as a benign electrocardiographic (ECG) finding.

What causes a left anterior fascicular block?

In the absence of manifest heart disease and in association with aging, left anterior fascicular block is attributed to degenerative disease of the conducting system,27 sclerosis of the left side of the cardiac skeleton,28 or myocardial fibrosis.

Is LPFB serious?

Although rare, LPFB is a clinically important intraventricular conduction disturbance. Its appearance is reliably connected with inferior wall MI and generally reflects severe two- or three-vessel disease, requiring invasive investigation [[11], [12], [13]].

What are the symptoms of left anterior fascicular block?

Individuals with left anterior fascicular block more often developed atrial fibrillation (p<0.001), congestive heart failure (p<0.001), and death (p<0.001), when compared to those without conduction disease.

Is left anterior fascicular block treatable?

The bottom EKG shows a reading of a person with left anterior fascicular block (LAFB), previously thought to be benign but found by a UCSF-led team to potentially signal a serious heart condition. There currently is no treatment for people with LAFB.

Can you have surgery with left anterior fascicular block?

In our case, the patient’s preoperative ECG showed left anterior fascicular block and sinus bradycardia. This is usually regarded as a low risk for surgery when the patient has normal ventricular function and is asymptomatic.

Is LAFB reversible?

Unfortunately LBBB is not reversible. In your case, in the absence of any structural heart disease and symptoms, the overall risk of cardiovascular morbidity or mortality should be very low.

Can you live a normal life with LAFB?

How serious is left posterior fascicular block?

There is no major clinical significance to the presence of a LPFB, except it indicates some degree of conduction system disease and thus a somewhat higher risk of progression to higher forms of heart block in the future.

Can I exercise with heart block?

Get regular exercise. Try for 2½ hours a week. If you do not have other heart problems, you likely do not have limits on the type or level of activity that you can do. You may want to walk, swim, bike, or do other activities.

Can heart block be caused by stress?

Studies suggest that the high levels of cortisol from long-term stress can increase blood cholesterol, triglycerides, blood sugar, and blood pressure. These are common risk factors for heart disease. This stress can also cause changes that promote the buildup of plaque deposits in the arteries.
