Coronary Artery Disease Claimed Secondary to Hypertension
Coronary Artery Disease (VA diagnostic code 7005) is sometimes claimed as secondary to service-connected Hypertension (code 7101) under 38 CFR 3.310. This page reports what published Board of Veterans' Appeals decisions on that pairing show. It is an encyclopedic reference, not a forecast.
What published Board decisions show
Across 832 published Board (BVA) decisions in our index where coronary artery disease was claimed as secondary to hypertension, the outcomes broke down as follows. These are historical aggregates of decided appeals, not a prediction for any individual claim.
Counting only appeals that were granted or denied (setting aside remands), about 55% were granted. A remand is not a loss; it means the Board needed more evidence before deciding.
Source: aggregate of published BVA decisions indexed by RateMyVSO, as of July 2026. Secondary service connection rule: 38 CFR § 3.310. Figures describe decided appeals and can change as new decisions are indexed.
Quick Checklist Before You File
- Service connection already in place for Hypertension, and a current medical diagnosis of coronary artery disease.
- Diagnostic testing, imaging, or clinical records documenting the coronary artery disease, whatever your provider used to diagnose and track it.
- A nexus opinion, whenever possible from a doctor familiar with coronary artery disease, stating it is at least as likely as not caused or aggravated by the hypertension, and naming the mechanism rather than just the conclusion.
- Lay statements: spouse, family, friends, or battle buddies describing what they've witnessed or noticed.
- Your STRs and any VA opinions already in the file on either condition. If a VA opinion already went against you, your submitted opinion or statement should address its specific reasoning.
For the mechanics of filing itself, see the Standard Claim Guide and the Fully Developed Claim Guide.
Why coronary artery disease is claimed secondary to hypertension
Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).
What a secondary claim on this pairing needs
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: Hypertension, already service-connected (the primary). A 0% primary still counts.
- A medical nexus: a medical opinion linking the coronary artery disease to the hypertension, 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.
Do's and Don'ts
- Get service connection established for Hypertension and a current diagnosis of coronary artery disease documented before you file.
- Get a nexus opinion that names the specific mechanism connecting the coronary artery disease to the hypertension and cites supporting literature, not just a conclusion.
- Include diagnostic testing, imaging, or clinical records for the coronary artery disease.
- Get a spouse, family, friend, or buddy statement describing what they've witnessed, lay evidence the Board credits directly.
- If a VA opinion already exists in your file, have your own opinion rebut it point by point rather than simply asserting the opposite conclusion.
- Don't accept "the study shows an association, not causation" as the final word, exact etiology and scientific consensus are not the legal standard (Alemany v. Brown, 9 Vet. App. 518 (1996); Wise v. Shinseki, 26 Vet. App. 517 (2014)).
- Don't treat a VA examiner's "unable to determine without speculating" as evidence against you, an unexplained non-opinion is not evidence at all.
- Don't let a service-to-diagnosis time gap sink your secondary claim, that gap matters for a direct claim, not this one.
- Don't assume you need an expensive specialist, a treating provider's notes plus published literature have carried grants before.
- Don't leave a negative opinion unchallenged if it never engaged your submitted literature or lay statements, the Board has downgraded exactly that kind of opinion to minimal weight.
The Claims Process, Step by Step
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.
- You file the claim, naming Hypertension as the service-connected primary and coronary artery disease as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
- 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.
- The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
- 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.
- VA issues the decision letter stating the outcome and the reasoning.
- 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
Your VSO
An accredited representative, agent, or attorney. Not a VA employee. Helps prepare and file, and can represent you on appeal. Has no authority to decide your claim.
VSR
VA staff who develops the claim: gathers records and schedules the exam. Does not decide the rating.
Rater (RVSR)
VA staff who reviews the complete file and makes the actual decision on service connection and percentage.
C&P Examiner
Conducts the exam and, where asked, gives a nexus opinion. Does not decide the claim, but the opinion's reasoning and legal framing carry real weight.
For the full walkthrough, see Inside Your Claim and Claim Stages.
DBQs and Your C&P Exam
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 hypertension timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.
Reading Your Decision Letter, and What to Do If Denied
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.
Not sure which lane fits? See the Appeals decision guide for a side-by-side comparison.
After You Win: Maintaining Your Rating
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.
Frequently Asked Questions
Does Hypertension have to be highly rated to support a coronary artery disease secondary claim?
No. 38 CFR 3.310 looks at whether the service-connected Hypertension caused or aggravated the coronary artery disease, not at how severe the Hypertension rating is. Even a 0% service-connected primary can anchor a secondary claim.
What do the percentages on this page mean?
They are the historical outcomes of 832 published Board decisions on this exact pairing: 31% granted, 25% denied, 41% remanded. They describe decided appeals already on record. They do not predict what would happen in any individual case.
