Hypertension Secondary to PTSD

Overview

Hypertension is one of the most common physical conditions claimed secondary to PTSD. The theory is that PTSD’s chronic stress response (constant hyperarousal, poor sleep, and the behaviors that come with them) raises blood pressure over time. A large VA cohort study now backs this up for veterans specifically.

Under 38 CFR § 3.310, you can claim hypertension because PTSD caused it or because PTSD aggravated hypertension you already had. Hypertension is rated separately from PTSD under Diagnostic Code 7101, so the rating adds to your combined percentage. Whether you get 0% or 10% usually depends on one detail: your blood pressure readings from before you started medication.

How Hypertension Is Connected to PTSD

Veteran-specific evidence. Burg and colleagues (Psychosomatic Medicine, 2017) followed 194,319 veterans who deployed after September 2001 and used VA care. Over a median of 2.4 years, PTSD was independently associated with a 12% to 30% higher risk of new hypertension, depending on the model. Veterans with untreated PTSD had the highest risk: a hazard ratio of 1.44, compared with 1.20 for those who received PTSD treatment. That also matters for your claim: engaging in PTSD treatment is not evidence against you.

Broader cardiovascular evidence. A 2017 review in Lancet Psychiatry (Edmondson and von Känel) concluded that PTSD is a risk factor for incident cardiovascular disease. It identified several candidate mechanisms and noted that research is still establishing which matter most.

Proposed mechanisms. The pathways most often cited are:

• sustained sympathetic nervous system activation (the hyperarousal cluster of PTSD)
• disrupted stress-hormone (HPA axis) regulation
• low-grade inflammation
• endothelial dysfunction
• poor sleep, including insomnia and nightmares

Behavioral and medication pathways. PTSD is associated with alcohol use, smoking, inactivity, and weight gain, all of which raise blood pressure. Some psychiatric medications can also contribute. Venlafaxine, an SNRI used for PTSD, raised diastolic blood pressure in a dose-dependent way that was clinically significant mainly above 300 mg/day in a large meta-analysis (Thase, 1998). If your blood pressure rose after a medication change, point that out to your clinician. A condition caused by medication taken for a service-connected disability can be claimed as secondary to that disability.

Evidence Requirements

• A diagnosis that meets VA’s definition. For VA purposes, hypertension means diastolic pressure predominantly 90 mm or greater. Isolated systolic hypertension means systolic pressure predominantly 160 mm or greater with diastolic below 90. The initial diagnosis must be confirmed by readings taken two or more times on at least three different days (DC 7101, Note 1).
• Pre-treatment readings. Records from before your first blood pressure prescription decide whether the “history of diastolic 100 or more” path to 10% applies.
• Proof of service-connected PTSD: your rating decision.
• Medical opinion: a clinician’s opinion that your hypertension is at least as likely as not caused or aggravated by PTSD, addressing your other risk factors.
• Timeline: records showing when PTSD symptoms began and when blood pressure first rose.
• Medication records: antihypertensives and psychiatric medications, with start dates and dose changes.
• Lay statements from you or family describing how your symptoms have progressed over time.

Agent Orange note. If you served in Vietnam, Thailand, or another herbicide-exposure location, hypertension has been presumptive since the 2022 PACT Act (38 U.S.C. § 1116). That route doesn’t require a nexus opinion.

Nexus Letter Tips

Any qualified clinician can write the opinion: a primary care physician, internist, cardiologist, psychiatrist, nurse practitioner, or physician assistant. VA weighs the reasoning, not the specialty.

A persuasive opinion should:

• State that your records were reviewed, including PTSD treatment and blood pressure history
• Give the “at least as likely as not (50% or greater probability) caused by or aggravated by” conclusion
• Explain the mechanism in your case and cite research such as Burg et al. (2017)
• Address age, weight, family history, alcohol, and smoking directly. PTSD doesn’t have to be the only cause, but the opinion must explain why it remains at least as likely as not a cause or aggravating factor despite them.
• Discuss medication effects if relevant

Aggravation. If hypertension was diagnosed before PTSD was service-connected, or before PTSD symptoms began, the claim is usually aggravation under 38 CFR § 3.310(b). VA requires the baseline severity to be established by medical evidence from before the worsening, or by the earliest evidence between the onset of aggravation and the current evidence. VA then rates only the increase above that baseline. Useful evidence includes older readings, the number of medications you needed then compared with now, and blood pressure spikes documented during PTSD crises.

Rating Criteria for Hypertension

Hypertension is rated under DC 7101 (38 CFR § 4.104):

10% Rating

Diastolic pressure predominantly 100 or more, or systolic pressure predominantly 160 or more. This is also the minimum evaluation for someone with a history of diastolic pressure predominantly 100 or more who requires continuous medication for control.

Monthly compensation at 10% (single veteran, no dependents, 2026): $180.42

20% Rating

Diastolic pressure predominantly 110 or more, or systolic pressure predominantly 200 or more.

40% Rating

Diastolic pressure predominantly 120 or more.

60% Rating

Diastolic pressure predominantly 130 or more.

Rating Notes

• 0% is common. If you’re on medication but your records never showed diastolic readings predominantly at 100 or more, VA assigns 0% (38 CFR § 4.31). A 0% rating still establishes service connection.
• “Predominantly” means the pattern, drawn from clinic visits, VA appointments, and home logs, not a single reading.
• Rated separately from heart disease (DC 7101, Note 3). Also rated separately from PTSD.

How to File This Secondary Claim

1. Confirm the diagnosis meets VA’s definition, with readings on at least three different days.
2. Collect pre-treatment readings from your earliest primary care or VA records.
3. Obtain a medical opinion that addresses causation or aggravation and your other risk factors.
4. File VA Form 21-526EZ on VA.gov, listing hypertension as secondary to service-connected PTSD, and upload your evidence.
5. Attend the C&P exam.

C&P Exam Tips

The examiner completes the Hypertension Disability Benefits Questionnaire. It asks:

• whether your diagnosis was confirmed by readings taken two or more times on three different days
• whether you take continuous medication
• whether you have a history of diastolic pressure predominantly 100 or more
• for three current seated readings

To prepare:

• Take your medication as prescribed. Don’t skip doses.
• Bring your history: highlight pre-medication readings of 100 or more diastolic, if you have them, and bring your home log with dates and times.
• Bring a medication list with start dates for antihypertensive and psychiatric medications.
• Explain the PTSD timeline: when symptoms began, when blood pressure rose, and any documented spikes during PTSD episodes.
• Mention complications such as kidney changes or heart findings. These are rated separately under their own codes.

Impact on Combined Rating

Example: A veteran with a 70% PTSD rating receives 10% for hypertension secondary to PTSD.

1. Start with 70%: remaining efficiency = 30%
2. Apply 10%: 10% of 30 = 3
3. Combined value: 73, which rounds to 70%

In this case the 10% rating doesn’t change the combined rating by itself, but it can once other ratings are added:

Example with multiple conditions: A veteran is rated 70% for PTSD, 50% for sleep apnea, and 10% for hypertension.

1. Start with 70%: remaining efficiency = 30%
2. Apply 50%: 50% of 30 = 15, for a combined value of 85
3. Apply 10%: 10% of 15 = 1.5, for 86.5. The 38 CFR § 4.25 table shows this as 87.
4. 87 rounds to 90%
