Understanding Heart Disease / CAD VA Disability
Coronary artery disease (CAD) and other forms of ischemic heart disease are serious VA disability conditions with significant potential compensation. The VA rates heart disease under 38 CFR § 4.104, Diagnostic Code 7005, based on METs (metabolic equivalents) on exercise tolerance testing, ejection fraction, and workload limitations. CAD is a recognized presumptive condition for veterans exposed to Agent Orange.
VA Rating Schedule for Heart Disease / CAD
The VA rates heart disease / cad under the VA Schedule for Rating Disabilities (38 CFR). The following table shows each possible rating level and what it represents clinically. Your rating is based on the severity of symptoms documented during a Compensation and Pension (C&P) examination and supported by your medical records.
| Rating | Clinical Criteria & Functional Impairment |
|---|---|
| 0% | History of CAD with successful revascularization and no residual symptoms; normal ejection fraction. |
| 10% | Minimal symptoms at rest or during exertion; more than 7 METs on exercise testing. |
| 30% | Symptoms with moderate exertion; 5-7 METs; ejection fraction of 50-55%. |
| 60% | Symptoms with mild exertion; 3-5 METs; ejection fraction 30-50%; or workload limitations. |
| 100% | Symptoms at rest or less than 3 METs; ejection fraction 30% or less; or chronic congestive heart failure. |
How a Nexus Letter Helps Your Heart Disease / CAD VA Claim
A nexus letter is a medical opinion, written and signed by a licensed physician, that establishes the connection between a veteran's current diagnosis and their military service. The VA requires this "nexus" as one of three elements for service connection under 38 CFR § 3.303: a current diagnosis, an in-service event or injury, and a medical link between the two.
A nexus letter for heart disease may be needed for direct service connection or for veterans who do not qualify for the Agent Orange presumption. For Agent Orange-exposed veterans (Vietnam, Korea DMZ, certain other locations): ischemic heart disease is a presumptive condition under 38 CFR § 3.309(e) — no nexus letter required. For non-presumptive claims: the nexus letter must establish a medically plausible connection between the in-service exposure or event and CAD development. This may include sustained physical and psychological stress, toxic exposures outside Agent Orange presumptions, or documented cardiac events during service. The physician should reference literature on stress-related cardiac disease and the specific risk factors the veteran was exposed to.
Semper Solutus provides MD-authored nexus letters written by physicians experienced in VA rating criteria and 38 CFR standards. Our letters use the "at least as likely as not" language required by VA adjudication standards and include a thorough review of all available medical records.
Secondary Conditions Commonly Linked to Heart Disease / CAD
When a condition is caused or aggravated by a service-connected disability, it may qualify for secondary service connection under 38 CFR § 3.310. This means veterans with service-connected heart disease / cad may be able to claim additional compensation for related conditions. The following conditions are frequently documented as secondary to heart disease / cad:
Hypertension
Service-connected hypertension is a well-established risk factor for secondary coronary artery disease.
Diabetes Type II
Service-connected diabetes type II is a major risk factor for secondary CAD.
Sleep Apnea
Untreated sleep apnea significantly increases cardiovascular risk.
Hypothyroidism
Hypothyroidism is associated with elevated cardiovascular risk and hyperlipidemia.
Medical Evidence That Strengthens a Heart Disease / CAD VA Claim
Key evidence: cardiac diagnostic records (stress test with METs, echocardiogram with ejection fraction, cardiac catheterization); surgical records (stent, bypass); cardiologist records; medication list including cardiac medications; evidence of Agent Orange exposure if applicable; and a nexus letter for non-presumptive claims.
Frequently Asked Questions: Heart Disease / CAD VA Disability
Yes. Ischemic heart disease is a presumptive condition for veterans with documented Agent Orange exposure under 38 CFR § 3.309(e). Veterans only need to establish exposure and a current diagnosis — no nexus letter required.
METs (metabolic equivalents) measure the maximum workload achieved during exercise stress testing. The number of METs at which symptoms develop directly determines the rating. Lower METs with symptoms = higher rating.
Yes. Both service-connected hypertension and diabetes type II are major risk factors for CAD. If these conditions are service-connected and your physician documents they contributed to your CAD, secondary service connection is possible with a nexus letter.
Post-revascularization with no residual symptoms typically results in a 0% or 10% rating. However, if symptoms persist after revascularization, the rating reflects the current level of exercise tolerance and ejection fraction.
