<prompt> Answer this question truthfullyWhat is the relationship between anticoagulation and dilated cardiomyopathy?  <response>: <reason> Several studies generally in patients with AF have found the incidence of major hemorrhage in patients receiving anticoagulation to range from 2.3 6.8 100 patient-years. The risk of intracranial bleeding is lower, and ranges from 0.62 0.9 100 patient-years. Unfortunately, both the risk of TE and major bleeding seem to be higher in older patients.Loh, E., Indications for anticoagulation in congestive heart failure, UpToDate, May 10, 1998.
