Patients diagnosed by electrocardiogram with left anterior fascicular block (LAFB), which involves scarring in a section of the hearts' left ventricle, had a 2.3-fold increased risk of congestive heart failure, an 89% increased risk of atrial fibrillation, and a 57% increased risk of dying over an average follow-up of 15.7 years in a recent JAMA analysis. The analysis included individuals in the Cardiovascular Health Study who were aged 65 years or older and were sampled from Medicare eligibility lists nationwide. Until now, LAFB was considered a benign electrocardiographic finding.
