Two heart conditions now sit on the VA’s Agent Orange presumptive list: ischemic heart disease and hypertension. The bottom line for a veteran with either diagnosis is that the claim no longer hinges on proving a direct link to service.
The numbers behind the claims
Heart disease is a common cause of hospitalization among veterans, and the VA’s Annual Benefits Report for 2024 shows service-connected cardiovascular disability still climbing. More than 750,000 veterans receive compensation for hypertension. Nearly 255,000 more are paid for arteriosclerotic disease, which includes coronary artery disease. Ratings run from 10% to 100%.
The wider medical picture explains the volume. Coronary artery disease affected 110 million people worldwide in 2015 and caused 8.9 million deaths that year. In the United States in 2010, about 20% of people over 65 had it, and rates were higher in men than in women of the same age.
What the presumption covers
Under 38 CFR 3.309(e) and the PACT Act, the VA treats a listed illness as service connected when the veteran also has qualifying service. No nexus letter is needed. The list applies to exposure to tactical herbicides generally, not just Agent Orange: Agent Blue, White, Purple, Pink and Green are covered too.
Ischemic heart disease takes in coronary artery disease, angina and myocardial infarction. It leaves out hypertension, peripheral vascular disease and cerebrovascular disease, so a veteran with both hypertension and ischemic heart disease should file the two separately. Each can carry its own rating.
Location matters as much as diagnosis. Service in Vietnam, Thailand, Korea or another qualifying area during the Vietnam War era is the second half of the test. Three conditions carry a clock, though. Chloracne, early-onset peripheral neuropathy and porphyria cutanea tarda must reach 10% or more within one year of last exposure. Ischemic heart disease has no such limit.
How the rating works
Most heart conditions are rated under the General Rating Formula, which turns on METs, a measure of how much exertion a person can take before symptoms such as shortness of breath, fatigue, dizziness or chest pain appear. The lower the MET tolerance, the higher the rating.
The benchmarks are concrete. Three METs or less is sitting and writing. Five is roughly mowing the lawn, seven an easy jog, ten a moderate run. A veteran who cannot manage even light daily activity without cardiac symptoms can reach 100%. One who needs continuous medication but has no other limitation gets 10%.
The formula covers coronary artery disease and ischemic heart disease, hypertensive heart disease, cardiomyopathy, aortic stenosis and valvular disease, residuals of pericarditis, murmurs and congestive heart failure. Cardiomyopathy, aortic stenosis and murmurs are not on the Agent Orange list, so those claims need a direct or secondary connection.
The figure that matters at the exam is the veteran’s worst days. Symptoms fluctuate, and the rating follows functional limits, not the best afternoon of the month. A formal stress test supplies the METs result. Without one, the VA may fall back on medication use alone, which means 10%.
