What Is the VA Rating for Heart Disease? DC 7005 Criteria, METs Testing, and the Agent Orange Presumptive Path

Heart disease is one of the most common conditions among veterans, and ischemic heart disease (IHD) — which includes coronary artery disease (CAD) — is rated under one of the most compensated diagnostic codes in the VA system.

But here is the problem: the rating criteria changed significantly in November 2021, and most online guides still publish outdated information.

This guide covers the current DC 7005 rating criteria, how METs testing works (including interview-based METs), the Agent Orange presumptive pathway, secondary conditions, post-surgery ratings, and exactly what to say at your C&P exam.

DC 7005 Rating Criteria (Current — Post-November 2021)

VA rates coronary artery disease and ischemic heart disease under 38 CFR § 4.104, Diagnostic Code 7005. Since the November 14, 2021 VASRD overhaul, ratings are based primarily on METs (Metabolic Equivalents of Task) exercise tolerance testing.

Here are the four rating levels:

The critical question at your C&P exam is: at what workload level do you experience cardiac symptoms? Those symptoms are specifically dyspnea (shortness of breath), fatigue, angina (chest pain), dizziness, or syncope (fainting).

METs Testing and Interview-Based METs

METs stands for Metabolic Equivalents of Task. It measures how much energy your body uses during physical activity compared to rest.

Here is what METs levels look like in daily life:

Exercise Stress Testing

The gold standard is an exercise stress test (usually on a treadmill) where the examiner measures your actual METs capacity while monitoring your heart. The test stops when you develop symptoms or reach your limit.

Interview-Based METs Estimation

Here is what many veterans do not know: exercise testing is not always required.

Under Note 2 of the General Rating Formula (38 CFR § 4.104), when exercise testing is medically contraindicated — for example, due to musculoskeletal limitations, obesity, or the cardiac condition itself — the examiner can estimate your METs capacity through an interview.

BVA decisions confirm that interview-based METs estimation is valid. In BVA 24002999, the Board upheld a rating based on interview METs of ">5–7 METs" where the examiner confirmed the limitation was due solely to CAD.

The "Due Solely" METs Requirement

VA examiners must determine whether your METs limitation is due solely to your heart condition. If you have other conditions affecting your exercise tolerance — such as COPD, obesity, or orthopedic problems — the examiner may try to separate out how much limitation comes from each condition.

But here is the critical rule that can save your claim:

When the examiner cannot separate which portion of the METs limitation is due to your heart disease versus other conditions, the Mittleider rule requires attributing the entire METs limitation to your service-connected condition. This comes from BVA 22071464, and it can mean the difference between a 30% and a 60% rating.

The 2021 LVEF Change (What Most Guides Get Wrong)

Before November 14, 2021, VA heart disease ratings included two additional criteria that could qualify you for higher ratings:

The November 14, 2021 VASRD overhaul (86 FR 54093) eliminated LVEF and standalone CHF as rating criteria for new claims filed after that date. Under the current criteria, only METs testing (and cardiac hypertrophy/dilatation for 30%) determines your rating.

Here is why this matters:

Many commercial legal sites — including well-known VA claims firms — still publish the old LVEF/CHF criteria without noting that they were removed in 2021 for new claims. If you rely on outdated guidance expecting your LVEF of 40% to automatically get you 60%, you may be in for a surprise.

Protection for Pre-2021 Ratings

If you had a heart disease claim or appeal pending as of November 14, 2021, the old criteria still apply when they produce a more favorable result. The controlling legal authority is VAOPGCPREC 07-03 (November 19, 2003), which holds that "a new rule may not extinguish any rights or benefits the claimant had prior to the enactment of the new rule."

BVA 25002360 (2025) — the most current BVA decision on this issue — explicitly cites VAOPGCPREC 07-03 and applies a bifurcated time-period analysis: old criteria for periods predating November 14, 2021, and new criteria after, using whichever is more favorable at each interval.

Agent Orange Presumptive Path for Ischemic Heart Disease

Ischemic heart disease — including coronary artery disease, angina, and heart attacks — is a presumptive condition for veterans exposed to Agent Orange or other tactical herbicides.

This means Vietnam-era veterans diagnosed with IHD do not need a nexus letter proving direct causation. VA presumes the connection to service based on herbicide exposure alone.

Who Qualifies

• Veterans who served in Vietnam between 1962 and 1975
• Veterans who served in Thailand at certain Royal Thai Air Force Bases during the Vietnam era
• Veterans exposed to Agent Orange during testing or storage at specific locations
• Veterans who served on C-123 aircraft used to spray Agent Orange

What Counts as Ischemic Heart Disease

Under 38 CFR § 3.309(e), ischemic heart disease includes:

• Coronary artery disease (atherosclerotic heart disease)
• Angina pectoris (chest pain from reduced blood flow)
• Myocardial infarction (heart attack)
• Acute, subacute, and old myocardial infarction

Ischemic heart disease does not include hypertension, peripheral vascular disease, or heart conditions not caused by reduced coronary blood flow.

IHD Is NOT a PACT Act Burn Pit Presumptive

This is a common source of confusion. IHD was made presumptive under Agent Orange in 2010 — before the PACT Act. The PACT Act expanded presumptives for post-9/11 and Gulf War veterans exposed to burn pits, but IHD is not among those burn pit presumptives.

Gulf War veterans without Agent Orange exposure who develop IHD will need a direct nexus letter establishing the connection to service.

Hypertension: The New Agent Orange Presumptive (January 2025)

As of January 8, 2025, hypertension (high blood pressure) was officially added as an Agent Orange presumptive condition. This creates a powerful opportunity for Vietnam-era veterans.

Under Note 3 of DC 7101, VA is required to rate hypertension separately from heart disease. The two conditions use completely different criteria — blood pressure readings for hypertension versus METs for heart disease — so there is no anti-pyramiding conflict.

All Four Service Connection Pathways

Not every veteran qualifies for the Agent Orange presumptive. Here are all four pathways to service-connect heart disease:

1. Agent Orange Presumptive

As described above — Vietnam-era veterans with IHD. No nexus letter required. The strongest and simplest pathway.

2. Former POW Presumptive

Former prisoners of war who develop atherosclerotic heart disease or hypertensive vascular disease have a separate presumptive pathway under 38 CFR § 3.309(c).

3. Secondary Service Connection

Veterans whose heart disease was caused or aggravated by another service-connected condition. Common secondary pathways include:

• PTSD → IHD: Chronic physiologic stress, elevated catecholamines, and autonomic dysregulation from PTSD accelerate cardiovascular disease. BVA 1513277 granted IHD secondary to PTSD based on aggravation nexus.
• Hypertension → IHD: Longstanding uncontrolled hypertension damages coronary arteries. BVA 21064277 granted IHD simultaneously as Agent Orange presumptive AND secondary to hypertension.
• Diabetes → IHD: Type 2 diabetes accelerates atherosclerosis and damages coronary blood vessels. This is especially powerful for Vietnam-era veterans since diabetes is also an Agent Orange presumptive.
• Sleep apnea → IHD: Intermittent hypoxia from OSA promotes atherosclerosis. Note: this direction is contested at the examiner level — BVA 1234773 shows a VA examiner denying it. A strong private nexus letter is recommended.
• Above-knee amputation → IHD: Under 38 CFR § 3.310(b), veterans with service-connected above-knee amputation who develop CAD have an automatic secondary connection. No nexus letter needed.

4. Direct Service Connection

For veterans without a presumptive or secondary pathway, direct service connection requires: (1) a current diagnosis, (2) an in-service event or exposure, and (3) a nexus letter linking the two. This is the most difficult pathway but remains available.

Secondary Conditions to Heart Disease

Once your heart disease is service-connected, it can serve as the foundation for additional secondary claims that increase your combined rating.

Here is what most veterans miss:

Conditions You CAN Claim Secondary to IHD

• Sleep apnea (DC 6847) — rated at 50% if CPAP required. Well-established pathway: heart failure from IHD causes sleep apnea. Rated under completely different criteria (CPAP-based, not METs), so both carry full ratings.
• Atrial fibrillation (DC 7010) — rated at 10% or 30%. CAD damages the heart's electrical system, leading to AFib. Separately ratable under its own diagnostic code.
• Hypertension (DC 7101) — if not already service-connected. Note 3 mandates separate rating from heart disease.
• Peripheral vascular disease (DC 7114) — atherosclerosis affecting the extremities.
• Chronic kidney disease — cardiorenal syndrome from heart failure can damage kidneys. Potentially separately ratable under renal diagnostic codes.
• Erectile dysfunction — cardiovascular disease commonly causes ED. While typically rated at 0%, it qualifies for SMC-K ($139.87/month added to any rating).

What You CANNOT Claim Separately

The METs Anti-Double-Counting Rule

Under 38 CFR § 4.104 Note, only one body system can use METs for rating purposes. If you have both heart disease (METs-based) and a respiratory condition like COPD, the respiratory condition must be rated using alternative criteria.

Good news: sleep apnea is not affected by this rule. Sleep apnea is rated under DC 6847 based on CPAP requirement, not METs. So both your IHD rating and sleep apnea rating can stand at full value simultaneously.

Post-Surgery and Temporary 100% Ratings

VA provides temporary 100% ratings for 3 months following major cardiac procedures. After 3 months, VA re-evaluates based on your METs capacity.

Procedures That Trigger Temporary 100%

• Myocardial infarction (heart attack) — DC 7006
• Coronary bypass surgery — DC 7017
• Heart valve replacement
• Pacemaker implantation
• Defibrillator (ICD) implantation

The 3-month 100% rating begins from the date of the event or surgery. After 3 months, VA schedules a new C&P exam to assess your current METs capacity and assign a permanent rating.

2026 Monthly Compensation Rates

Here are the official VA compensation rates for 2026 (effective December 1, 2025, reflecting a 2.8% COLA increase):

Veterans rated 30% or higher receive additional compensation for qualifying dependents (spouse, children, dependent parents).

C&P Exam Tips for Heart Disease

The C&P exam determines your rating. Preparation is everything.

Before the Exam

• Know your METs threshold. Think about what activities cause cardiac symptoms. Write them down. Translate daily activities into METs levels using the table above.
• Document your worst days. If your symptoms fluctuate, the examiner needs to know about your bad days — not just your best days.
• Bring your medication list. Every cardiac medication you take supports your claim.
• Bring recent test results. Echocardiograms, stress tests, cardiac catheterization reports, and any evidence of hypertrophy or dilatation.

During the Exam

These three statements can make or break your rating:

1. Describe symptoms at specific activity levels: "I get short of breath and chest tightness walking from my car to the grocery store entrance" (approximately 3–4 METs). Be specific about the activity and the symptoms.
2. Name all five qualifying symptoms: Dyspnea, fatigue, angina, dizziness, and syncope. If you experience any of these, make sure the examiner documents each one.
3. Address comorbidities for Mittleider: If you have other conditions affecting your exercise tolerance, tell the examiner. If they cannot separate the METs limitation between your heart disease and other conditions, the Mittleider rule requires attributing the full limitation to your service-connected heart disease.

After the Exam

• Request a copy of the completed DBQ (Disability Benefits Questionnaire)
• Check that the examiner documented your METs level accurately
• Verify they noted all cardiac symptoms you reported
• If the examiner states a higher METs capacity than your daily life reflects, file a written objection immediately

TDIU and the SMC-S Gateway

If your heart disease prevents you from working but you do not meet the schedular 100% criteria, you may qualify for TDIU (Total Disability based on Individual Unemployability).

TDIU Qualification

Under 38 CFR § 4.16(a), a single service-connected disability rated at 60% or higher qualifies you for TDIU if you cannot secure substantially gainful employment. A 60% IHD rating meets this threshold on its own.

TDIU pays the same rate as 100%: $3,938.58 per month in 2026.

The Bradley v. Peake SMC-S Gateway

This is the multi-hop connection that no one talks about:

Under Bradley v. Peake, 22 Vet. App. 280 (2008), TDIU based on a single disability satisfies the SMC-S (Special Monthly Compensation — Housebound) "single 100%" requirement.

Here is how this works for heart disease veterans:

1. You have IHD rated at 60% and cannot work → you qualify for TDIU
2. That TDIU satisfies the SMC-S "single disability rated at 100%" threshold
3. If you also have a separate service-connected condition rated at 60% or higher (for example, hypertension at 60%), you qualify for SMC-S housebound
4. SMC-S pays approximately $400+ per month above the standard 100% rate
