Coronary Artery Disease Secondary to PTSD Claim Guide

We analyzed the Board's published decisions and found coronary artery disease (DC 7005) claimed as secondary to PTSD (DC 9411) is a real, mid-sized claim pool that loses more often than it wins once it reaches a merits decision.

How those 1,073 issues came out

The ICD-10 diagnosis codes most commonly used for DC 7005, Coronary Artery Disease (the kind on your medical records, decision letter, or C&P exam report). VA rates the disability and its residuals, not the diagnosis itself, so coding can vary.

See the full diagnostic-code page →

Under 38 CFR 3.310 a secondary claim turns on three elements:

• A current diagnosis: a medical diagnosis of coronary artery disease (the secondary).
• A service-connected primary: PTSD, already service-connected (the primary). A 0% primary still counts.
• A medical nexus: a medical opinion linking the coronary artery disease to the PTSD, showing the primary caused or aggravated it.

See the Secondary Claim guide for the caused-versus-aggravated split, and the Nexus Letter guide for what makes the medical opinion strong.

Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).

The outcome split above counts whole issues. This section goes one layer deeper. Under 38 CFR § 3.310 a secondary claim can be won two ways: the PTSD caused the coronary artery disease (§ 3.310(a)), or it aggravated an existing coronary artery disease (§ 3.310(b)). Every grant rests on one or the other, so the numbers below divide up the granted claims only.

Direct causation is the route that carries most grants here: 81% of them found the PTSD caused the coronary artery disease, the rest found aggravation. A practical consequence for the nexus opinion: it should address both routes, because a medical opinion that only argues causation leaves the aggravation theory, a separate legal basis, on the table. See the caused-vs-aggravated guide for how the two theories differ.

On the other side: in 79 denied claims the Board looked at this pairing and found no link, meaning it decided the PTSD neither caused nor worsened the coronary artery disease. That is a separate group from the grants above, counted here so the picture is not one-sided.

We analyzed published Board decisions on this pairing to build this split. The grant split covers granted claims only; denied, remanded, and dismissed claims are not in it. Descriptive of the published record, not a prediction.

The record VA actually reviews centers on a small set of documents. We analyzed published Board decisions on these claims and ranked the records that appeared most often:

• A medical nexus opinion: the one record VA weighs most on a secondary claim, a doctor's statement linking your coronary artery disease to your service-connected ptsd and naming the mechanism.
• Heart attack, stent, or bypass documented
• Stress test or echocardiogram in the record
• Ischemic heart disease herbicide presumption addressed
• Ejection fraction measured
• METs workload testing documented

The diagnostic code involved: DC 7005 (Coronary Artery Disease). The rating levels for this code are in the rating section below.

Records ranked by how often published Board decisions cited them. The exam that captures most of this is covered in the C&P Exam section below. Source: Board of Veterans' Appeals decisions, RateMyVSO analysis.

What veterans who win this pairing actually put in the file, and why each piece moves the claim.

• Exercise stress test with a measured METs score: get a real treadmill or bicycle stress test, not an examiner's guess at how much activity you can handle. VA raters lean on the METs number to set your rating, so a formal test protects you from being lowballed on effort tolerance.
• Cardiac imaging that proves the diagnosis: gather your EKG, echocardiogram, or catheterization results. This shows the VA hard proof of blockage or heart damage, so they cannot deny you for "no evidence of structural heart disease."
• A full cardiology paper trail: pull your records showing when CAD was first diagnosed and every treatment since. A clear timeline helps show your heart disease came after, or got worse after, your PTSD symptoms took hold.
• Blood pressure and lab readings: collect blood pressure logs and any lipid or inflammation bloodwork. These numbers back up the medical chain from PTSD to heart disease: constant stress hormones raise blood pressure and inflammation, and that damages your arteries over time. Numbers make this harder to wave off as "just lifestyle."
• Your PTSD treatment records, including hyperarousal episodes: bring records that show your PTSD symptoms, especially episodes of being on edge, panic, or nightmares. If you can show a flare-up happened around the same time as a cardiac symptom, that timing helps prove the connection.
• Sleep problems documented in writing: get a sleep study or your therapist's notes on insomnia. Poor sleep from PTSD raises blood pressure and strains your heart on its own, and examiners often miss this link unless it's spelled out.
• A nexus opinion that covers both causation and aggravation, and explains the "why": a doctor's letter needs to say your CAD is "at least as likely as not" (50% or more) caused or made worse by your service-connected PTSD, and it must walk through the chain step by step: PTSD keeps your body flooded with stress hormones, that raises blood pressure and inflammation, and over years that damages your arteries. A letter that just lists both conditions without explaining the link is the single biggest reason these claims get denied. Make sure it also answers any obvious pushback, like smoking or cholesterol, by explaining PTSD made things worse on top of those factors, not instead of them.
• A personal symptom journal: keep simple notes on when chest symptoms, high readings, or heart episodes line up with PTSD triggers like nightmares, anniversaries, or loud noises. Your own timeline, in your own words, adds real-time proof the nexus letter can point back to.

The Board has granted service connection for coronary artery disease (CAD) as secondary to PTSD in several published decisions. These decisions are not binding precedent, and each case turned on its own medical record. The pattern below shows what kind of evidence tended to succeed. Keep in mind that a published win does not predict any other outcome.

The VA assigns one of these percentages based on what your medical record documents. Plain-language summary of the rating criteria at 38 CFR; the controlling text is the regulation itself.

Every item below comes from a pattern in the decisions on this pairing, not from general claim advice.

For the mechanics of filing itself, see the Standard Claim Guide and the Fully Developed Claim Guide.

A secondary claim moves through the same pipeline as any other. Understanding who does what helps you know who to contact and what to expect.

1. You file the claim, naming PTSD as the service-connected primary and coronary artery disease as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
2. VA assigns a Veteran Service Representative (VSR) to develop the claim: gather your service treatment records, VA and private medical records, and order a C&P exam if needed.
3. The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
4. The file goes to a Rating Veteran Service Representative (RVSR), the "rater," who weighs the medical evidence and decides service connection and, if granted, the rating percentage.
5. VA issues the decision letter stating the outcome and the reasoning.
6. If denied or under-rated, you choose an appeal lane, Supplemental Claim, Higher-Level Review, or a Board appeal, covered below.

Who's who: VSO vs. VSR vs. Rater vs. C&P Examiner

For the full walkthrough, see Inside Your Claim and Claim Stages.

A Disability Benefits Questionnaire (DBQ) is the standardized form the examiner completes for your condition. See the DBQ Guide for how these forms work and whether a private DBQ from your own doctor can be submitted instead of relying solely on a VA exam. For what to expect and how to prepare, see the C&P Exam Prep Guide, and be specific about how your coronary artery disease symptoms relate to your PTSD timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.

Your decision letter has a narrative "reasons and bases" section and a codesheet with the rating and effective date. See the Reading Your Decision Letter Guide or use the Letter Interpreter tool to decode your own letter. If denied, you have three main lanes:

• Supplemental Claim: refile with new and relevant evidence, such as a nexus opinion that addresses the mechanism and the specific VA rationale you're rebutting. See Supplemental Claim Guide.
• Higher-Level Review (HLR): a senior reviewer looks at the same evidence again, useful if the denial rested on a legal error. See HLR Guide.
• Board Appeal: your case goes to a Veterans Law Judge, with a direct review, evidence, or hearing docket. See Board Appeal Guide.

Keep documentation of ongoing treatment, follow-up evaluations, and any updated diagnostic testing for your coronary artery disease on file, this protects you if VA schedules a future reexamination. See Protect Your Rating for when a rating becomes protected and Future Reexaminations for what triggers one. If your coronary artery disease worsens, see the Rating Increase Guide.
