Agent Orange Heart Disease VA Disability Rating: Criteria, Evidence & Pay

What is Agent Orange heart disease and how does it affect veterans?

Agent Orange heart disease refers to ischemic heart disease that develops in veterans who were exposed to Agent Orange and other tactical herbicides during military service. Ischemic heart disease occurs when the arteries supplying blood to the heart become narrowed or blocked, reducing oxygen delivery to the heart muscle. This includes coronary artery disease, angina (chest pain), myocardial infarction (heart attack), and other conditions caused by inadequate blood supply to the heart.

Agent Orange — a mixture of the herbicides 2,4-D and 2,4,5-T contaminated with dioxin (TCDD) — was sprayed extensively during the Vietnam War to defoliate forests and destroy enemy crops. Approximately 2.6 million U.S. military personnel served in Vietnam, and many were exposed to this toxic chemical. Scientific research has established a clear link between Agent Orange/dioxin exposure and the development of ischemic heart disease, often manifesting years or decades after exposure.

The VA added ischemic heart disease to the list of Agent Orange presumptive conditions in 2010. This means that if you served in a qualifying location and have been diagnosed with ischemic heart disease, the VA presumes the disease is connected to your herbicide exposure — no nexus letter is required.

VA diagnostic code for Agent Orange heart disease

Agent Orange-related ischemic heart disease is rated under Diagnostic Code (DC) 7005 per 38 CFR § 4.104, Schedule of Ratings — Cardiovascular System. DC 7005 covers arteriosclerotic heart disease (coronary artery disease), which is the most common form of ischemic heart disease among Agent Orange veterans.

The rating criteria are based on exercise capacity measured in METs (metabolic equivalents of task), left ventricular ejection fraction (EF), and the presence of congestive heart failure (CHF). The VA uses whichever criteria produces the higher rating for the veteran.

Rating criteria for Agent Orange heart disease

The VA assigns Agent Orange heart disease ratings at five possible levels. Here’s what each rating requires and what it pays in 2026:

0% rating

Criteria: Ischemic heart disease has been diagnosed and service-connected, but cardiac testing shows a workload greater than 7 METs without symptoms such as dyspnea (shortness of breath), fatigue, angina (chest pain), dizziness, or syncope (fainting), and there is no evidence of cardiac hypertrophy or dilatation on testing.

Monthly payment: $0 (but establishes service connection, which is critical for future increases as the condition progresses and for secondary condition claims)

10% rating — $180.42/month

Criteria: A workload of greater than 7 METs but not greater than 10 METs that results in dyspnea, fatigue, angina, dizziness, or syncope, or continuous medication is required for control.

What this looks like: You take daily heart medication (beta blockers, statins, blood thinners) and experience mild symptoms during vigorous activity. You can perform most daily activities without problems, but heavy exercise or strenuous work causes chest tightness, shortness of breath, or fatigue.

30% rating — $552.47/month

Criteria: A workload of greater than 5 METs but not greater than 7 METs that results in dyspnea, fatigue, angina, dizziness, or syncope, or evidence of cardiac hypertrophy or dilatation on electrocardiogram, echocardiogram, or X-ray.

What this looks like: Moderate physical activities such as brisk walking, climbing a flight of stairs, mowing the lawn, or carrying groceries cause noticeable cardiac symptoms. Your heart may show structural changes (enlargement) on imaging. You take multiple medications and may have had cardiac procedures (stenting, angioplasty).

60% rating — $1,435.02/month

Criteria: More than one episode of acute congestive heart failure in the past year, or a workload of greater than 3 METs but not greater than 5 METs that results in dyspnea, fatigue, angina, dizziness, or syncope, or left ventricular dysfunction with an ejection fraction of 30% to 50%.

What this looks like: Routine daily activities cause cardiac symptoms. Walking short distances, light housework, or getting dressed may produce shortness of breath or fatigue. Your heart does not pump blood as efficiently as it should (reduced ejection fraction). You may have experienced episodes of congestive heart failure requiring medical intervention. Employment involving any physical activity is extremely difficult.

100% rating — $3,938.58/month

Criteria: Chronic congestive heart failure, or a workload of 3 METs or less that results in dyspnea, fatigue, angina, dizziness, or syncope, or left ventricular dysfunction with an ejection fraction of less than 30%.

What this looks like: Your heart disease is severe and life-limiting. Even minimal physical activity causes significant cardiac symptoms. You may have chronic congestive heart failure requiring ongoing management. Your heart’s pumping function is severely compromised. You are unable to maintain employment in any capacity, and daily activities require assistance or cause distress.

What evidence do you need?

The presumptive service connection for Agent Orange heart disease simplifies the claims process significantly, but you still need to document your condition and qualifying service:

Service records

• DD-214 confirming service in Vietnam between January 9, 1962, and May 7, 1975
• Or documentation of service at qualifying Thailand military bases, C-123 aircraft, or herbicide test/storage sites
• Deployment records, orders, or personnel records confirming dates and locations
• Service treatment records are helpful but not required for presumptive claims

Medical evidence

• Current diagnosis of ischemic heart disease from a cardiologist or qualified physician
• Cardiac testing results — echocardiogram showing ejection fraction, stress test showing METs capacity, EKG results
• Cardiac catheterization results if performed
• Records of any heart procedures (stenting, angioplasty, bypass surgery)
• Treatment records showing ongoing symptoms and medication use
• Documentation of any congestive heart failure episodes

Nexus letter

A nexus letter is generally not required for Agent Orange presumptive conditions. The VA presumes the connection between your qualifying service and ischemic heart disease. However, if your claim is denied or if there is a question about whether your specific cardiac condition qualifies as ischemic heart disease, a cardiologist’s opinion can be valuable.

Buddy statements

Statements from family members, friends, or fellow veterans who can describe:

• Your cardiac symptoms and how they limit your activities
• Changes in your physical abilities over time
• Your service in Vietnam or other qualifying locations
• How heart disease has affected your daily life and ability to work

Personal statement

Your own detailed account of how ischemic heart disease affects your daily life. Be specific about limitations — describe how far you can walk before symptoms occur, which daily activities cause problems, and how your condition has changed over time. For example, instead of “I have heart problems,” write “I cannot walk more than one block without chest pain and shortness of breath, and I had to quit my job as a warehouse worker because I could no longer lift anything over 10 pounds without becoming dizzy.”

C&P exam tips for Agent Orange heart disease

The C&P exam for heart disease focuses heavily on objective cardiac testing, but accurately communicating your symptoms is equally important.

What the examiner evaluates

The examiner will assess:

• Your current cardiac diagnosis and history
• METs capacity — either through an exercise stress test or an interview-based estimate if you cannot exercise safely
• Left ventricular ejection fraction from recent echocardiogram
• Whether you have or have had congestive heart failure
• Current medications and treatments
• Impact on occupational and daily functioning
• History of cardiac procedures (bypass, stenting, pacemaker)

How to prepare

1. Bring all recent cardiac test results. Echocardiograms, stress tests, EKGs, and cardiac catheterization reports. Having recent results (within the past year) is important.
2. Be honest about your limitations. If you cannot climb stairs without chest pain, say so. If you stopped exercising because of your heart, explain that.
3. Know your METs level. Think about what activities cause symptoms. For reference: 1-3 METs = dressing, eating, walking slowly; 3-5 METs = light yard work, brisk walking; 5-7 METs = mowing lawn, climbing stairs; 7-10 METs = jogging, heavy yard work.
4. Report all symptoms. Chest pain, shortness of breath, fatigue, dizziness, swelling in legs/ankles, irregular heartbeat — describe when and how often each occurs.
5. Describe the trajectory. Heart disease typically worsens over time. Explain how your symptoms and limitations have progressed.

Common mistakes

• Underreporting symptoms because “it could be worse” — describe your actual limitations
• Not having recent cardiac testing (stress test, echocardiogram) — if your last test is over a year old, ask your cardiologist for updated testing before your C&P exam
• Failing to mention episodes of congestive heart failure or emergency room visits
• Not connecting symptoms to daily activities and work limitations
• Exercising or being unusually active before the exam, which can temporarily affect test results

Common secondary conditions linked to Agent Orange heart disease

Agent Orange exposure and the resulting heart disease frequently cause or aggravate other conditions. These can be claimed as secondary service-connected disabilities:

• Depression — Heart disease is strongly linked to depression. The physical limitations, medication side effects, and life changes caused by chronic heart disease frequently trigger depressive episodes. Research shows that cardiac patients have depression rates 2-3 times higher than the general population.
• Sleep apnea — Heart disease and sleep apnea share a bidirectional relationship. Heart failure can cause central sleep apnea, and the medications and reduced activity from heart disease can contribute to weight gain and obstructive sleep apnea.
• Diabetes — Many Agent Orange veterans have both heart disease and Type 2 diabetes (also a presumptive condition). Diabetes can worsen heart disease and is frequently claimed as a separate service-connected condition.
• Erectile dysfunction — Heart disease and the medications used to treat it (beta blockers, statins) commonly cause erectile dysfunction. Reduced blood flow from cardiovascular disease directly affects sexual function.
