What Veterans Should Know About VA Ratings for Heart Conditions Linked to PTSD

Veterans living with post-traumatic stress disorder (PTSD) face long-term physical health risks that can change everything from a daily routine to long-term earning ability. Cardiovascular disease is one of the clearest examples. Decades of research, including longitudinal studies of Vietnam-era veterans, show that combat-related PTSD significantly raises the likelihood of heart disease, hypertension, and arrhythmias. When those conditions develop or worsen because of service-connected PTSD, the Department of Veterans Affairs may award secondary service connection and a separate disability rating. Understanding how the VA assigns those ratings is the first step toward making sure that combined compensation reflects the full impact of service. 

At the Law Office of Sean Kendall, our experienced Boulder Veterans disability benefits lawyers help clients nationwide fight for the benefits they earned through service. Here's what you should know about how the VA rates heart conditions linked to PTSD and how our team can help you navigate the complex VA disability claims process. 

How the VA Rates Heart Conditions 

The VA rates most cardiovascular conditions under 38 CFR, Part 4, the Schedule for Rating Disabilities. The VA looks at three core measurements: a workload measurement called Metabolic Equivalents (METs), left ventricular ejection fraction, and the level of treatment a Veteran requires. Each diagnostic code has its own rating criteria, but the framework is consistent. 

METs and Workload Testing 

METs scores measure how much physical exertion a Veteran can tolerate before symptoms such as chest pain, shortness of breath, fatigue, or dizziness appear. Lower METs scores reflect more severe disease. After a service-connected heart attack, for example, the VA assigns a temporary 100 percent rating for three months, then re-evaluates using METs. 

• 100 percent: METs of three or less, or chronic congestive heart failure 

• 60 percent: METs of greater than three but not greater than five, or ejection fraction between 30 and 50 percent 

• 30 percent: METs of greater than five but not greater than seven, with evidence of cardiac hypertrophy or dilatation 

• 10 percent: METs of greater than seven but not greater than 10, or continuous medication required 

Hypertension and Arrhythmias 

The VA rates hypertension under diagnostic code 7101 based on diastolic and systolic readings, while atrial fibrillation, supraventricular tachycardia, and other rhythm disorders fall under their own codes.  Veterans dealing with atrial fibrillation tied to PTSD should document every episode, every cardioversion, and every medication change because the frequency of attacks drives the rating percentage. 

Why PTSD Matters in a Heart Disease Claim 

PTSD keeps the body in a sustained fight-or-flight state. Extensive research shows the physiological link between chronic stress and cardiovascular disease: persistent cortisol release, inflammation, sleep disruption, and behavioral changes such as smoking or heavy drinking all push the heart toward earlier disease. Veterans with severe PTSD are up to 60 percent more likely to develop heart disease than peers without it, and they often develop those conditions years earlier.

Under 38 CFR § 3.310, a disability that is proximately caused or aggravated by a service-connected condition can itself be service-connected. That regulation is the legal foundation for every PTSD-to-heart claim. The Court of Appeals for Veterans Claims has reinforced that aggravation alone, not just direct causation, can support secondary service connection, as in Wise v. Shinseki. 

Building a Secondary Service Connection Claim 

A successful secondary claim has three pillars. The first is an existing service-connected diagnosis of PTSD. The second is medical evidence of a current cardiovascular condition, including objective testing such as EKGs, echocardiograms, stress tests, or cardiac catheterization. The third is a medical nexus opinion linking the heart condition to the PTSD. Strong nexus letters from qualified clinicians are often the difference between approval and denial. 

Common Heart Conditions Connected to PTSD 

Research shows a link between PTSD and numerous heart conditions, including:

• Coronary artery disease and ischemic heart disease 

• Hypertension and hypertensive heart disease 

• Atrial fibrillation and other arrhythmias 

• Cardiomyopathy and congestive heart failure 

• Stroke and post-stroke cardiac complications 

Combined Ratings and TDIU Eligibility 

VA disability ratings do not stack the way most Veterans expect. The agency uses a combined ratings table, sometimes called VA Math, that calculates each new rating against the remaining percentage of an unimpaired Veteran. A Veteran already rated 70 percent for PTSD who receives an additional 30 percent for coronary artery disease will see a combined rating closer to 80 percent than 100 percent. Even so, the financial difference between rating tiers can be hundreds or thousands of dollars per month.

Heart conditions can also unlock Total Disability Individual Unemployability benefits, commonly known as TDIU. A Veteran who cannot maintain substantially gainful employment because of service-connected disabilities may be paid at the 100 percent rate even when the schedular total is lower. To qualify, a veteran usually needs one disability rated at 60 percent or two or more disabilities with a combined rating of 70 percent, at least one of which has a 40 percent rating. PTSD plus a moderate heart condition often satisfies that threshold and provides a clear path to TDIU. 

Documentation That Strengthens a Heart-PTSD Claim 

Cardiology records should establish the date of diagnosis, severity, treatment plan, and functional limits. Mental health records should document PTSD symptoms over time, especially periods of acute hyperarousal that correspond with cardiac events. Pharmacy records can show whether PTSD medications such as SSRIs or antipsychotics contributed to weight gain, hypertension, or rhythm changes. Veterans pursuing benefits for cardiovascular conditions secondary to mental health diagnoses should keep a symptom journal that ties cardiac flare-ups to PTSD triggers, sleep disruption, and stress. 

Why Working with a Veterans Benefits Lawyer Matters 

The VA initially denies many secondary heart claims because the file lacks a clear nexus opinion or because the rater treats the cardiovascular condition as a lifestyle issue rather than a service-related consequence. An experienced Veterans benefits lawyer can identify the right experts, develop the medical record, and present arguments that align with binding case law, including precedential decisions such as Wise v. Shinseki on aggravation. Skilled representation also matters when the appeal moves to a Board hearing or to the Court of Appeals for Veterans Claims.

Heart conditions tied to PTSD can change a veteran's life and livelihood. Understanding how the VA assigns ratings, how those ratings combine, and how a strong evidentiary record supports a TDIU claim is essential to securing every dollar of compensation a Veteran has earned.
