As of December 2014, there is no known therapy to treat a left anterior fascicular block. However, a biventricular pacemaker, also known as cardiac resynchronization therapy, may be used to help prevent heart failure associated with this disorder, according to University of California San Francisco.Continue Reading
A biventricular pacemaker is a battery-powered device used to balance the heart's contractions in patients that show delays in ventricular action within the heart. This therapy is done for people with advanced heart failure, notes Cleveland Clinic.
In April 2013, researchers announced new findings with regard to left anterior fascicular blocks, or LAFB, a heart condition previously thought to be harmless. Scarring in the left ventricle of the heart led to greater instances of atrial fibrillation, congestive heart failure and death in otherwise healthy patients over the age of 65, notes UCSF. Risk of heart failure increased by 143 percent in patients with LAFB. Doctors plan to study specialized pacemakers as a possible treatment for LAFB in order to prevent heart failure. Lifestyle changes, exercise and not using tobacco are other ways to help reduce the overall risk of heart problems.
LAFB prevents electrical signals from reaching parts of the left ventricle of the heart, according to UCSF. As of December 2014, researchers don't known why or how fibrosis, or scarring of the heart, is associated with this electrical block.Learn more about Cardiac Health
Levels of heart block are first-degree, second-degree and third-degree heart block. Second-degree heart block is split into two subtypes known as Mobitz I and Mobitz II, according to the National Heart, Lung and Blood Institute. Mobitz I occurs when the electric signal delay with each heartbeat, causing the heart to skip beats. Mobitz II occurs when some of the signals move to the atria and ventricles, while others do not.Full Answer >
Ways to prevent aortic vascular calcification include the use of bisphosphonates, phosphate binders and thiosulfate therapy. Additionally, increasing vitamin K intake and limiting calcium circulation averts calcification, according to O'Neill and Lomashvili for Kidney International.Full Answer >
Heart failure that has not responded to standard therapy, such as medication or surgery, is one indication for a heart transplant, according to MedlinePlus. Overall, 80 percent of patients who receive a transplanted heart are alive two years after the procedure, and 70 percent are alive after five years. The main barrier to a successful transplant is rejection of the donor heart. If doctors are able to control rejection, overall survival time increases to 10 years.Full Answer >
According to the National Heart, Lung, and Blood Institute, heart attack treatments include oxygen, aspirin therapy and nitroglycerin. Aspirin therapy helps to prevent blood clots, while nitroglycerin helps to stabilize blood flow through the coronary system. In addition to blood clotting medications, angioplasty may be required. It is a nonsurgical procedure in which a tube is inserted into an artery to remove blockages.Full Answer >
