Hypertension Secondary to PTSD
High blood pressure claimed as secondary to PTSD is the second most-filed PTSD secondary claim at the Board of Veterans' Appeals, behind only sleep apnea. It wins less than half the time it reaches a merits decision, but a surprising number of the grants below turned on the VA's own examiner undercutting the VA's own denial. This guide covers the stress-hormone mechanism, the legal standard under 38 CFR § 3.310 including how the Spicer but-for standard can turn a "risk factors outweigh PTSD" denial into a concession, five recent Board grants dissected, and the evidence that separates the wins from the losses.
The Numbers, from 1.9 Million Appeals
In the Board's published decisions, hypertension (DC 7101) claimed as secondary to PTSD (DC 9411) is the second most-filed PTSD secondary by volume, trailing only sleep apnea, and one of the harder pairings to win outright.
How those 3,806 issues came out
Compare the companion pairings: sleep apnea secondary to PTSD wins 67 percent of decided issues, migraines 74 percent, GERD a near coin-flip at 51 percent. Hypertension's 41 percent is the toughest of the four, and the reason shows up in the case law below: VA's own examiners frequently write opinions that list competing risk factors (age, weight, family history, cholesterol) without engaging the multi-causal "but-for" standard the Federal Circuit actually requires, and the Board has started reading those opinions against VA rather than for it.
Quick Checklist Before You File
- Documented blood pressure history in your treatment records, a pattern of readings, not a single reading.
- A nexus opinion that addresses both causation and aggravation, not just one.
- One identified mechanism (sympathetic nervous system overactivity, HPA-axis/cortisol dysfunction, or sleep disruption and lost nocturnal dipping) that matches your actual record.
- Your own psychiatric symptom and treatment timeline pulled, not just the formal PTSD diagnosis date.
- Any VA opinion in your file read closely for "outweigh" or similar language that may concede rather than defeat the claim.
- Supporting medical literature cited where available (metabolic-syndrome research, the POW-presumption rulemaking record, or similar).
For the mechanics of filing itself, see the Standard Claim Guide and the Fully Developed Claim Guide.
The Legal Path: 38 CFR § 3.310, and When VA's Own Opinion Concedes the Claim
A secondary service connection claim needs three things (Wallin v. West, 11 Vet. App. 509 (1998)):
- A current disability: a diagnosed hypertension, which for DC 7101 means a documented pattern of blood pressure readings meeting the rating threshold, diastolic readings of 100 or more, not a single reading.
- A service-connected primary: the PTSD rating itself.
- A nexus: medical evidence connecting the two.
The shared doctrine (multi-step chains, the equipoise standard, the baseline trap on aggravation) is covered in depth in the companion guide: Sleep Apnea Secondary to PTSD. Two points are specific to how the hypertension cases have played out:
The Mechanism: How PTSD Connects to Hypertension (expand to read)
The credited opinions in recent grants describe a consistent physiological chain from PTSD to sustained high blood pressure, not a single trigger.
1. Sympathetic nervous system overactivity
PTSD keeps the sympathetic nervous system, the body's "fight-or-flight" branch, in a state of prolonged overactivation. Elevated epinephrine and norepinephrine during PTSD symptom flares raise heart rate and constrict blood vessels, producing repeated blood pressure spikes that can become chronic hypertension over time.
2. HPA-axis and cortisol dysfunction
Chronic PTSD disrupts the hypothalamic-pituitary-adrenal (HPA) axis, the body's central stress-hormone regulator. Abnormal cortisol levels drive sodium retention and increased vascular pressure, a slower-acting but cumulative pathway distinct from the moment-to-moment adrenaline spikes.
3. Sleep disruption and the loss of nocturnal dipping
Blood pressure normally drops at night ("nocturnal dipping"). PTSD-driven nightmares and insomnia interrupt that cycle, and the loss of the nighttime dip is itself an independent cardiovascular risk factor tracked in the sleep-medicine literature.
4. The population-level evidence VA has already accepted once
VA's own rulemaking supports the link: a presumption of service connection for hypertensive vascular disease applies to former prisoners of war, based on medical studies showing veterans with long-term PTSD carry a high risk of developing cardiovascular disease. See 70 Fed. Reg. 37040 (June 28, 2005); 69 Fed. Reg. 60083 (Oct. 7, 2004), both cited directly in one of the grants below (Bd. Vet. App. A26002980). A veteran with a chronic, non-POW-derived PTSD does not get the presumption itself, but the underlying medical basis VA relied on to create it is available as literature evidence in an ordinary secondary claim.
"Risk factors outweigh PTSD" can be read as a concession (expand to read)
Under Spicer v. McDonough, 61 F.4th 1360 (Fed. Cir. 2023), the causation standard in 38 U.S.C. § 1110 is but-for causation, "not limited to a single cause and effect, but rather contemplates multi-causal links." In one January 2026 grant, a VA examiner listed family history, chronic pain, NSAID use, hypercholesterolemia, and obesity as risk factors that "outweigh PTSD" for developing hypertension. An unpublished CAVC memorandum decision the Board relied on, Gajeski v. Collins, No. 24-4992 (Vet. App. July 14, 2025), makes the point directly: establishing that other factors outweigh a cause "does not necessarily eliminate all other factors as but-for causes." The Board read the VA examiner's own language as implying PTSD is one cause among several, which is all the but-for standard requires (Bd. Vet. App. A26002980).
The missing aggravation prong (expand to read)
Any VA medical opinion addressing secondary service connection must include an aggravation analysis, not just causation. Ward v. Wilkie, 31 Vet. App. 233 (2019); 38 C.F.R. § 3.310(b). In one grant, the Board found six consecutive VA opinions across seven years inadequate, most for exactly this omission, alongside conclusory rationales that failed to engage the facts of the case (Bd. Vet. App. A25107192, citing Stefl v. Nicholson, 21 Vet. App. 120 (2007), and Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008)).
Five Recent Board Grants, Explained (expand to read)
All five decisions below granted service connection for hypertension secondary to PTSD, decided September 2025 through March 2026 before five different Veterans Law Judges. Published Board decisions are not precedent, but the patterns repeat.
The VA examiner's own words concede the claim · Citation A26002980 (Jan. 13, 2026), Evidence docket
The record: the May 2025 VA examiner gave a negative opinion, concluding that risk factors such as family history, chronic pain, NSAID use, hypercholesterolemia, and obesity "outweigh PTSD" as a cause of the Veteran's hypertension. The Veteran also submitted an American College of Cardiology study finding metabolic syndrome, including high blood pressure, in 53 percent of PTSD patients versus 38 percent of controls, and reported his primary care physician's opinion linking the two conditions.
Why it won: the but-for standard does multi-causal work. Under Spicer and the CAVC's Gajeski memorandum decision, saying other factors outweigh PTSD is not the same as saying PTSD is not a cause at all, it implies PTSD is one cause among several, which is enough. Combined with the medical-literature evidence and the Veteran's competent lay report of his physician's opinion (Jandreau), the Board found the evidence at least evenly balanced and granted.
Two VA examiners disagree; the Board picks the one that accounts for the record · Citation A26023532 (Mar. 16, 2026), Hearing docket, decided 55 years after separation
The record: the March 2025 VA examiner opined hypertension was at least as likely as not due to PTSD, citing literature on prolonged PTSD symptoms and blood pressure. The July 2025 VA examiner disagreed, reasoning the hypertension diagnosis predated the PTSD diagnosis.
Why it won: the July opinion missed the Veteran's actual timeline. He had reported psychiatric symptoms and treatment reaching back to the 1970s, including an impact on his first marriage, well before his formal PTSD diagnosis. The Board discounted the "predates PTSD" rationale as built on an incomplete picture and credited the March opinion instead.
Silent service records, a decades-later diagnosis, and one unopposed literature-based opinion · Citation A26023156 (Mar. 13, 2026), Hearing docket (withdrawn), Vietnam-era veteran
The record: service treatment records were silent for hypertension; the Veteran was diagnosed in 2013, decades after his 1975 discharge. A private clinician's March 2025 opinion cited medical literature supporting a link to the Veteran's service-connected PTSD.
Why it won: the opinion was reasoned, record-reviewed, and cited literature, entitling it to significant probative weight under Nieves-Rodriguez. VA never submitted a competing opinion. With nothing on the other side of the scale, equipoise was reached on the private opinion alone, decades-old silent service records notwithstanding.
Six inadequate VA opinions over seven years · Citation A25107192 (Dec. 11, 2025), Evidence docket, joint with a related heart-conditions grant
The record: across 2017 to 2024, four separate VA examiners issued negative opinions on the Veteran's heart conditions and hypertension. Each was found inadequate: some omitted the required aggravation prong entirely, others gave conclusory rationale that never engaged the Veteran's actual facts or the favorable evidence already in the file.
Why it won: a chain of defective opinions is not evidence against a claim, it is no evidence at all. Once the Board discounted all six, what remained (a November 2024 VA examiner's own acknowledgment that "PTSD can lead to anxiety and both can contribute to elevated blood pressure") was, while not elaborately detailed, still a discernible rationale the Board could credit. Equipoise, then the benefit of the doubt.
A private rehabilitation specialist ties two conditions to PTSD and tinnitus together · Citation A26024525 (Mar. 18, 2026), Direct Review docket
The record: the VA examiner denied both hypertension and sleep apnea, reasoning there was no documentation of either condition on the record before, during, or after service, and separately that they were not due to conceded toxic exposure. A private physician and rehabilitation specialist later reviewed the Veteran's full file, including buddy statements describing progressive in-service snoring, and opined both conditions were connected to and aggravated by the service-connected PTSD and tinnitus, citing medical articles on each linkage.
Why it won: the VA denial addressed only direct service connection and toxic exposure, never engaging the secondary theory at all. The private opinion did, with record review, corroborating buddy statements, and cited literature. Unopposed on the theory that actually mattered, the claim was granted.
The pattern across all five
- VA's own examiners repeatedly wrote opinions that helped the veteran without meaning to: risk factors framed as "outweighing" PTSD, or a passing acknowledgment that PTSD "can contribute" to blood pressure, read as concessions under the but-for standard rather than denials.
- The missing aggravation prong is a recurring, fixable defect. Multiple opinions across these cases were discounted for addressing causation only, never aggravation, a requirement under Ward v. Wilkie that VA examiners routinely skip.
- Medical literature carries real weight here. The American College of Cardiology study, the POW-presumption rulemaking record, and general PTSD-hypertension research all appeared as credited evidence, not just doctor-authored opinions.
- Equipoise carried at least three of the five. None of the five grants required a strong, unambiguous positive opinion; a tie, reached through a defective VA opinion or supporting literature, was enough.
The Evidence Checklist (expand to read)
What the winning files contained, item by item.
- A documented diagnosis: hypertension confirmed in your treatment records, ideally with a blood pressure history rather than a single reading, since the Board weighs a documented pattern more heavily than an isolated data point.
- Both prongs addressed: a nexus opinion must speak to causation and aggravation. Missing the aggravation prong sank multiple VA opinions across these five cases (Ward v. Wilkie). If you are submitting a private opinion, make sure your clinician addresses both.
- The chain, matched to your record: the winning theories drew on sympathetic nervous system overactivity, HPA-axis and cortisol dysfunction, or sleep disruption. A nexus opinion that names the specific mechanism and ties it to your treatment history outperforms a generic assertion.
- Medical literature: the American College of Cardiology metabolic-syndrome study and the POW-presumption rulemaking record both did real work in these grants. A clinician does not need to be your specialist to cite the literature; the Board weighs a reasoned literature-based opinion (Nieves-Rodriguez).
- A close read of VA's own opinion: language framing other risk factors as merely "outweighing" PTSD, rather than excluding it, can support your claim under the but-for standard. Do not assume a negative-sounding opinion is actually negative until you read exactly what it concedes.
Across all published DC 7101 decisions, files with a private medical opinion track a different grant rate than VA-exam-only files, shown live below.
Why VA Denies These Claims, and What the Board Said Back (expand to read)
Each rationale below is quoted or paraphrased from the actual VA examinations in the five cases, alongside how the Board answered it.
| VA examiner's rationale | How the Board answered it |
|---|---|
| Risk factors (family history, chronic pain, NSAID use, hypercholesterolemia, obesity) "outweigh PTSD" as a cause. | Under the but-for, multi-causal standard, saying other factors outweigh PTSD implies PTSD is still one cause. That is enough to support, not defeat, the claim (A26002980). |
| Hypertension diagnosis "predated" the PTSD diagnosis. | Discounted where the record showed psychiatric symptoms and treatment years before the formal PTSD diagnosis date; the rationale relied on an incomplete timeline (A26023532). |
| "No clinical data to support a nexus... hypertension is multifactorial, most often idiopathic." | The same opinion also acknowledged PTSD and anxiety "can contribute to elevated blood pressure." Not elaborately detailed, but a discernible, credited rationale (A25107192). |
| No documentation of hypertension "on the record pre, post, and while on active service." | Addresses only direct service connection, not the secondary theory actually raised; an unopposed private opinion with cited literature carried the secondary claim (A26024525). |
| Opinion omits the required aggravation analysis, addressing causation only. | Inadequate. Any secondary-service-connection opinion must include an aggravation prong (Ward v. Wilkie). Repeated across multiple opinions in the same file (A25107192). |
Across the Board's full record for hypertension, the most common denial reason is a missing nexus, shown live below.
Do's and Don'ts
A condensed version of the pattern across the five grants and the denial rationales above.
- Get a documented blood pressure history in your file, a pattern of readings over time, not one isolated data point.
- Make sure a nexus opinion addresses both causation and aggravation, missing the aggravation prong sank multiple VA opinions across these five cases.
- Pick the mechanism your record actually supports, sympathetic-nervous-system overactivity, HPA-axis and cortisol dysfunction, or sleep disruption and lost nocturnal dipping, and get an opinion built around that one.
- Read VA's own negative opinion closely. Language framing other risk factors as merely "outweighing" PTSD, rather than excluding it, can concede the but-for standard rather than defeat your claim.
- Pull your own psychiatric symptom and treatment history, not just the formal PTSD diagnosis date, a "predates PTSD" denial can be built on an incomplete timeline.
- Cite medical literature where you have it. The ACC metabolic-syndrome study and the POW-presumption rulemaking record both did real work in these grants, and a clinician does not need to be your specialist to reference the literature.
- Don't assume a "risk factors outweigh PTSD" opinion is a straightforward denial, under the but-for, multi-causal standard it can imply PTSD is still one cause among several.
- Don't accept a nexus opinion that addresses causation only, an opinion silent on aggravation is incomplete and can be discounted.
- Don't assume you need a cardiologist, the five grants ran on a private physician and rehabilitation specialist, VA's own examiners, and a private clinician citing general literature, not a specific credential.
- Don't take a "hypertension predates PTSD" rationale at face value, check whether your psychiatric symptoms and treatment actually reach back further than the formal diagnosis date.
- Don't assume a chain of defective VA opinions counts as evidence against you, a defective opinion is discounted, not weighed, and what remains can still favor your claim.

If Granted: The Rating
Hypertension is rated under DC 7101 (38 CFR § 4.104) primarily on the predominant diastolic reading: 10, 20, 40, and 60 percent tiers, with the 10 percent level also reachable through a documented history of diastolic readings of 100 or more paired with a current requirement for continuous medication. There is no 100 percent rating under this code alone. The secondary rating combines with your PTSD rating under VA math rather than adding, run it in the VA Math Calculator. Full rating detail, the six-reading confirmation requirement, and the medication-controlled minimum are in the general Hypertension Claims Guide.
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 PTSD as the service-connected primary and hypertension 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 as the case dissections above show, the opinion's reasoning and legal framing carry real weight, sometimes for the veteran even when the opinion itself is negative.
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. Bring your own blood pressure log if you have one, a documented pattern of readings carries more weight than a single in-office reading, and be specific about whether your psychiatric symptoms and treatment reach back further than your formal PTSD diagnosis date; several of the grants above turned on exactly that kind of detail being in the record.
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, or if the reasoning rests on risk factors "outweighing" PTSD, an opinion that skips the aggravation prong, or a "predates PTSD" rationale (see the discussion above), you have three main lanes:
- Supplemental Claim: refile with new and relevant evidence, such as a nexus opinion that addresses both causation and aggravation or medical literature VA never considered. 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 like reading "outweigh" language as a full denial or missing the aggravation analysis. 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 your blood pressure checkups and medication refills consistent and documented, an ongoing record 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 hypertension worsens or requires additional medication, you can file for an increased rating, see the Rating Increase Guide.
Frequently Asked Questions
Why is this pairing harder to win than sleep apnea, migraines, or GERD secondary to PTSD?
The published record puts hypertension at 41 percent of decided issues granted, the lowest of the four highest-volume PTSD secondaries. Hypertension has many well-documented non-PTSD causes (age, weight, diet, family history), so VA examiners default to attributing it to those factors without engaging the multi-causal standard the law actually requires. The grants above show that a close read of the VA opinion, plus a nexus addressing both causation and aggravation, can still win.
My denial says other risk factors "outweigh" my PTSD. Is that actually a denial?
Read it carefully. Under Spicer v. McDonough, the but-for causation standard is multi-causal, establishing that other factors are stronger does not eliminate PTSD as a cause. In one published grant the Board read exactly that language as implicitly conceding PTSD is one cause among several (A26002980). An unpublished CAVC decision, Gajeski v. Collins, makes the same point directly.
Does the VA's POW hypertension presumption help my non-POW claim?
Not directly, the presumption itself only applies to former prisoners of war. But the medical research VA relied on to create that presumption, showing veterans with long-term PTSD carry elevated cardiovascular risk, is available as literature evidence in an ordinary secondary claim, and was cited for exactly that purpose in a published grant (A26002980).
What is the aggravation prong, and why does it matter?
Secondary service connection can be established by causation (PTSD caused the hypertension) or aggravation (PTSD made pre-existing hypertension worse). A VA medical opinion addressing secondary service connection must analyze both, and an opinion that only addresses causation is incomplete. Six separate VA opinions across one Veteran's seven-year file were found inadequate largely on this ground (A25107192).
Do I need a cardiologist to write my nexus letter?
Not on this record. The five grants ran on a private physician and rehabilitation specialist, two VA examiners whose own language cut for the veteran, and a private clinician citing general medical literature. What mattered was a reasoned opinion addressing both causation and aggravation, matched to the veteran's actual treatment timeline, not a specific credential.
My hypertension was diagnosed years before my PTSD diagnosis. Does that rule out a secondary claim?
Not necessarily. In one grant, a VA examiner's "predates PTSD" denial was discounted because the Veteran's psychiatric symptoms and treatment reached back years before the formal PTSD diagnosis date (A26023532). A later formal diagnosis date is not the same as a later actual onset date, and aggravation theory covers worsening of a pre-existing condition regardless of which diagnosis came first.
