Heart disease is a common cause of hospitalization among veterans, and the Department of Veterans Affairs recognizes a broad range of cardiac and cardiovascular conditions for disability compensation, with ratings ranging from 10% to 100%.
The number of veterans with service-connected cardiovascular disabilities has been increasing according to the VA Annual Benefits Report for 2024, with over 750,000 veterans receiving compensation for hypertension and nearly 255,000 for arteriosclerotic (coronary artery) disease.
Both ischemic heart disease and hypertension are presumptive conditions for Agent Orange, which opens the door to benefits for Vietnam-era veterans. Even if your heart condition is not presumptive, you may still qualify through direct or secondary service connection.
How Does the VA Rate Heart Disease?
The VA rates most heart conditions under Diagnostic Codes 7000 through 7020 of 38 CFR Part 4, Section 4.104. Hypertension is rated separately under DC 7101 based on diastolic and systolic blood pressure readings (find out more about VA ratings for hypertension).
The General Rating Formula for Heart Disease is typically based on Metabolic Equivalents of Task (METs): a measure of how much physical exertion a person can tolerate before experiencing heart failure symptoms such as shortness of breath, fatigue, dizziness, or chest pain. The lower your MET tolerance, the more severe your disability and the higher your rating.
A MET of 3 or less generally corresponds to light tasks such as sitting and writing. A MET of 5 is approximately equivalent to mowing the lawn. A MET of 7 might correspond to jogging at an easy pace, and a MET of 10 to running at a moderate pace.
Veterans who cannot perform even light daily activities without cardiac symptoms may qualify for the highest heart disease ratings, up to 100%.
The General Rating Formula for Heart Disease
| Rating | Rating Criteria |
|---|---|
| 100% | Workload of 3.0 METs or less results in heart failure symptoms |
| 60% | Workload of 3.1-5.0 METs results in heart failure symptoms |
| 30% | Workload of 5.1-7.0 METs results in heart failure symptoms; or evidence of cardiac hypertrophy or dilatation confirmed by echocardiogram or equivalent |
| 10% | Workload of 7.1-10.0 METs results in heart failure symptoms; or continuous medication required for control |
The General Rating Formula applies to coronary artery disease and ischemic heart disease (DC 7005), hypertensive heart disease (DC 7007), cardiomyopathy (DC 7020), aortic stenosis and valvular heart disease (DC 7000), pericarditis residuals (DCs 7002, 7003), and most other heart conditions, such as:
- Heart murmur. Heart murmurs vary in severity, with some being harmless and others indicative of serious heart conditions. Veterans experiencing significant symptoms or complications may be eligible for disability benefits.
- Congestive heart failure, which occurs when the heart is unable to pump sufficient blood to meet the body’s needs (often caused by cardiomyopathy), leading to symptoms like fatigue, shortness of breath, and fluid buildup in the legs and lungs.
- Angina (chest pain caused by reduced blood flow to the heart)
- Arteriosclerosis and Atherosclerosis (hardening of the arteries that can lead to various heart conditions)
- Endocarditis (infection of the heart’s inner lining)
- Myocarditis (inflammation of the heart muscle)
For example, a veteran who experiences heart failure symptoms (such as shortness of breath, fatigue, or chest pain) when mowing the lawn (approximately 5 METs, within the 3.1-5.0 range) would qualify for a 60% rating.
A veteran who requires continuous cardiac medication but has no other functional limitation qualifies for a 10% rating. Use the VA disability calculator to estimate monthly compensation based on your rating.
Heart Arrhythmias
Heart arrhythmia is an irregular and often rapid heart rate that increases the risk of stroke, heart failure, and other complications. Irregular heart rhythm conditions include tachycardia, bradycardia and sick sinus syndrome.
Veterans with this condition may qualify for disability benefits depending on the severity and impact on their daily lives. This could include the placement of a pacemaker if necessary. See the ratings for heart arrhythmia.
Heart Surgery Ratings
Veterans who have undergone heart surgery or device implantation receive a temporary 100% rating during recovery, after which the underlying condition is reassessed under the General Rating Formula. A mandatory VA examination is required after each procedure period.
| Condition / Procedure | Diagnostic Code | Initial Rating | Reassessment |
|---|---|---|---|
| Myocardial Infarction (heart attack) | DC 7006 | 100% for 3 months following MI confirmed by laboratory tests | Mandatory exam; thereafter rate under General Rating Formula |
| Heart Valve Replacement (Prosthesis) | DC 7016 | 100% for an indefinite period following hospital admission for valve replacement | Mandatory exam 6 months post-discharge; thereafter rate under General Rating Formula |
| Coronary Bypass Surgery | DC 7017 | 100% for 3 months following hospital admission for surgery | Mandatory exam; thereafter rate under General Rating Formula |
| Implantable Cardiac Pacemaker | DC 7018 | 100% for one month following hospital discharge for implantation or re-implantation | Minimum 10% thereafter; evaluated as supraventricular tachycardia, ventricular arrhythmia, or AV block |
| Cardiac Transplantation | DC 7019 | 100% for a minimum of one year from date of hospital admission | Mandatory exam 1 year post-discharge; minimum 30% thereafter under General Rating Formula |
How to Establish Service Connection for Heart Disease
Service connection is the legal link between a veteran’s heart condition and military service. There are several pathways you can take, depending on your situation.
1. Agent Orange or Herbicide Exposure (Presumptive)
If you served in a qualifying location during a qualifying time period and have a current diagnosis of ischemic heart disease (including CAD, atherosclerosis, angina, or bypass surgery history) or hypertension, the VA presumes service connection.
This means that you do not need a nexus letter or any evidence of a specific in-service exposure event. Submit your DD-214 or other records showing qualifying service and your current medical diagnosis.
2. Chronic Disease Presumption (Within One Year of Service)
If you developed a compensable manifestation of cardiovascular-renal disease, including hypertension, within one year of separation from qualifying military service, the VA presumes service connection under 38 CFR 3.309(a).
3. Direct Service Connection
Veterans who do not qualify under a presumptive category can still establish direct service connection by showing three elements, according to Caluza v. Brown, 7 Vet. App. 508 (1995).
- A current diagnosis of a heart condition from a licensed healthcare provider
- An in-service event, injury, or illness: documented cardiac symptoms, a documented exposure event, known high-risk duty assignment, or physical stress from combat or operational conditions
- A medical nexus opinion: a statement from a qualified provider (cardiologist, internist, or VA examiner) that the current condition is ‘at least as likely as not’ caused or aggravated by the in-service event
Aggravation
If you had a pre-existing heart condition before service, and military service permanently worsened it beyond its natural progression, you may qualify for service connection on an aggravation theory.
This requires a medical opinion comparing the severity of the pre-existing condition with the current severity to show that service caused a permanent increase beyond the natural course of the disease.
4. Secondary Service Connection
A heart condition caused by or permanently worsened by an already service-connected condition qualifies for secondary service connection. Common examples include:
- Ischemic heart disease or coronary artery disease secondary to hypertension. Hypertension accelerates atherosclerosis and increases risk of heart attack and heart failure.
- Ischemic heart disease secondary to PTSD. Multiple studies have found higher rates of cardiovascular disease among veterans with PTSD, mediated by chronic physiologic stress, inflammation, and autonomic dysregulation.
- Coronary artery disease secondary to sleep apnea. Obstructive sleep apnea causes intermittent hypoxia and elevated catecholamines that promote atherosclerosis and increase risk of myocardial infarction.
- Hypertensive heart disease secondary to hypertension. Chronic high blood pressure causes structural changes to the heart muscle, resulting in left ventricular hypertrophy and eventually heart failure.
- Heart disease secondary to diabetes. Type 2 diabetes accelerates atherosclerosis, increases the risk of hypertension, and damages blood vessels throughout the body, including the coronary arteries.
How to Prove Your Claim
The nexus opinion is the most critical element for a non-presumptive direct claim. A letter that simply states the condition ‘may be related’ to service does not satisfy the legal standard. The opinion must say ‘at least as likely as not’ and explain how exactly the in-service event is connected to the diagnosis.
For example, from the 1950s through the 1980s, people living or working at the U.S. Marine Corps Base Camp Lejeune, North Carolina, were potentially exposed to contaminated drinking water.
Industrial solvents, such as trichloroethylene (TCE) and perchloroethylene (PCE), from dry-cleaning waste and benzene from leaking underground fuel storage tanks were detected in the water on the base.
Veterans who served at Camp Lejeune or MCAS New River between August 1, 1953, and December 31, 1987, for whom heart disease is not a presumptive condition, may pursue direct service connection with the help of a medical opinion supporting the link between toxic exposure in service and their diagnosis.

What Other Evidence Do You Need?
- Service records: DD-214 listing military occupational specialty (MOS), duty assignments, and locations; performance evaluations mentioning specific duties; deployment and assignment orders
- Individual Longitudinal Exposure Record (ILER): VA’s electronic system tracking deployment history, MOS, occupational hazards, and environmental exposures by time and location
- Medical records: treatment records from military service showing elevated blood pressure, cardiac symptoms, or related diagnoses; VA or private records post-separation
- Buddy statements: statements from fellow veterans describing shared exposure, working conditions, duration, and lack of personal protective equipment
- Environmental and base records: DoD environmental contamination databases, base industrial hygiene reports, hazardous material handling logs
- C&P exam reports: findings from Compensation and Pension exams that document heart disease, functional limitations, and any nexus opinion offered by the examiner
The Compensation and Pension Exam
After filing, the VA will schedule a Compensation and Pension exam to assess your current condition. For heart disease, the examiner will typically review your medical records, measure blood pressure, evaluate functional capacity, and may review or order additional testing.
During the exam, you should describe your worst days during the exam. Heart disease symptoms fluctuate, and the VA rating is based on your functional limitations, not your best days.
Mention how far you can walk before symptoms appear, whether you experience chest pain or shortness of breath with routine activity, whether you have had episodes of heart failure requiring hospitalization, and all medications you take for your heart condition.
The examiner will then prepare a Disability Benefits Questionnaire (DBQ) that includes a METs workload assessment, a review of cardiac imaging for signs of hypertrophy or dilatation, and an opinion about whether your heart condition may be related to your military service.
Heart Disease and Secondary Conditions
Heart disease and its treatment often cause or worsen other conditions that can be rated separately as service-connected disabilities. They include:
- Depression and anxiety: veterans with chronic cardiac illness experience higher rates of major depression and generalized anxiety disorder, evaluated by the VA under the mental health rating criteria
- Sleep apnea: obstructive sleep apnea is associated with heart failure, coronary artery disease, and arrhythmias
- Chronic kidney disease: reduced cardiac output in heart failure impairs renal perfusion, leading to cardiorenal syndrome
- Peripheral vascular disease: atherosclerosis affecting the coronary arteries often coexists with peripheral arterial disease, which is separately rated under DC 7114
- Erectile dysfunction: can entitle veterans to SMC-K when caused by vascular insufficiency or medication side effects from cardiac treatment
Can You Get VA Unemployability for Heart Disease?
If heart disease prevents you from keeping a job, you may qualify for Total Disability Based on Individual Unemployability (TDIU), which pays compensation at the 100% disability level even when your rating is lower.
Severe heart failure, post-surgical recovery, and METs limitations that restrict sustained physical activity are common bases for heart disease TDIU claims.
As established in Rice v. Shinseki, 22 Vet. App. 447 (2009), TDIU must be considered as part of any pending claim for a higher rating when the record reasonably raises the issue, even if you have not explicitly requested it.
In practice, many veterans miss out on the benefits they may be entitled to receive and may require help with the VA claims system. Hill & Ponton’s VA-accredited lawyers can assist you in pursuing a higher rating or TDIU, with no upfront costs.
Special Monthly Compensation for Heart Disease
Veterans with severe heart disease could also qualify for Special Monthly Compensation (SMC), which provides additional tax-free compensation above the standard disability rates.
- SMC-S (Housebound) may apply when heart failure substantially confines a veteran to their home, or when a 100% rating is combined with an additional service-connected disability rated at 60% or more.
- SMC-L (Aid and Attendance) helps pay for the regular help of another person if the veteran cannot manage daily activities alone due to end-stage heart failure or recovery from a major cardiac event.
- SMC-K is a flat-rate extra payment for specific losses, such as erectile dysfunction caused by insufficient blood flow or medication side effects.
For current SMC pay rates and complete eligibility requirements for each level, see our guide to Special Monthly Compensation.
Are You Making These Mistakes in Your Claim?
- Misidentifying the presumptive category: only ischemic heart disease and hypertension are presumptive for Agent Orange. Cardiomyopathy, aortic stenosis, and heart murmurs are not Agent Orange presumptive conditions. Filing these conditions as presumptive without a supporting nexus may result in denial; instead, pursue direct or secondary service connection.
- Failing to claim hypertension separately: hypertension is rated under its own diagnostic code (DC 7101) and is now a standalone Agent Orange presumptive. Veterans who have hypertension AND ischemic heart disease should file both separately, as each can carry its own rating.
- Not obtaining a formal stress test: the General Rating Formula for heart disease is typically based on METs workload. Without documented stress test results, the VA may rely on medication use alone (10%) rather than the higher functional limitation ratings (30% or 60%). Obtain formal exercise stress testing and submit the results with your claim.
- Underreporting symptoms at C&P: describe your worst days, not your average days. Mention any hospitalizations for chest pain or heart failure, how far you can walk before symptoms appear, and all cardiac medications you take.
- Not considering secondary conditions: sleep apnea, depression, kidney disease, and peripheral vascular disease may all be secondary to heart disease or to the same service-connected conditions that caused heart disease. Each additional rated condition increases the combined disability percentage.
How Hill & Ponton Can Help
Heart disease claims are medically complex. Rating criteria based on METs workload and heart failure symptoms require accurate medical evidence, correctly framed for the specific diagnostic code at issue.
Presumptive eligibility depends on service location and time period details that must be verified against the veteran’s records. Secondary conditions multiply the claim’s complexity and opportunity.
Hill & Ponton have successfully handled appeals for heart disease disability claims for decades. If the VA underrates or denies your claim, you are not alone.
