Veterans with myocardial infarction (heart attack) may qualify for VA disability benefits, as heart conditions are often linked to military service. Establishing service connection—whether direct, presumptive, or secondary—is crucial for securing compensation. The VA rates heart conditions based on METs testing, symptoms, and functional limitations, with temporary 100% ratings after major cardiac events or surgeries. Secondary conditions like arrhythmias, heart failure, and psychological impacts can increase a veteran’s overall disability rating. Proper documentation, medical evidence, and expert assistance can strengthen claims and ensure veterans receive the benefits they deserve.
