Cardiovascular disease ratings in the VA system are grounded in objective physiological measures rather than subjective symptom reports. Under 38 CFR 4.104, conditions like ischemic heart disease, cardiomyopathy, and coronary artery disease are rated primarily using two measures: metabolic equivalents, commonly called METs, and left ventricular ejection fraction. Understanding how these measures drive rating decisions helps veterans prepare for stress tests, echocardiograms, and C&P evaluations.
Diagnostic Code 7005 covers arteriosclerotic heart disease, also known as coronary artery disease. The rating levels are 10 percent for a workload of greater than 7 but not greater than 10 METs resulting in dyspnea, fatigue, angina, dizziness, or syncope, or continuous medication required. A 30 percent rating applies for a workload greater than 5 but not greater than 7 METs resulting in the same symptoms, or evidence of cardiac hypertrophy or dilatation on electrocardiogram, echocardiogram, or X-ray. A 60 percent rating applies for a workload greater than 3 but not greater than 5 METs resulting in those symptoms, or more than one episode of acute congestive heart failure in the past year, or left ventricular dysfunction with an ejection fraction of 30 to 50 percent. A 100 percent rating applies for chronic congestive heart failure, workload of 3 METs or less, or left ventricular dysfunction with ejection fraction less than 30 percent.
The same MET-based structure applies across most cardiac diagnostic codes, including DC 7006 for myocardial infarction, DC 7007 for hypertensive heart disease, DC 7011 for ventricular arrhythmias, DC 7015 for atrioventricular block, DC 7017 for coronary bypass surgery, DC 7018 for implantable cardiac pacemakers, DC 7019 for cardiac transplantation, and DC 7020 for cardiomyopathy. Each code has its own specific criteria but uses the METs framework for ongoing evaluation.
METs measurement is usually obtained through exercise stress testing. A formal stress test on a treadmill or stationary bike produces a direct measurement of the workload the heart can sustain. If the veteran cannot perform a stress test for medical reasons, the examiner may estimate METs based on the activities the veteran can perform without symptoms. Climbing one flight of stairs, for example, is approximately 4 METs. Walking on level ground at 3 mph is approximately 3 METs. Heavy yard work is approximately 5 to 6 METs.
Ejection fraction is a measurement of how efficiently the left ventricle pumps blood with each contraction. It is typically measured via echocardiogram, cardiac MRI, or nuclear imaging. A normal ejection fraction is 55 to 70 percent. An ejection fraction of 40 to 54 percent is considered mildly reduced. An ejection fraction of 30 to 39 percent is moderately reduced, and less than 30 percent is severely reduced. The rating criteria specifically mention the 30 to 50 percent band for a 60 percent rating and less than 30 percent for 100 percent.
Ischemic heart disease has special significance under the PACT Act and Agent Orange presumptive framework. For Vietnam-era veterans exposed to Agent Orange, ischemic heart disease is a presumptive condition under 38 CFR 3.309(e). This means covered veterans who develop ischemic heart disease do not need to prove a nexus between their condition and service. A diagnosis combined with qualifying service establishes service connection automatically. The PACT Act expanded the list of locations that qualify as covered service for Agent Orange exposure, including Thailand, Korean DMZ, and certain other locations during specified time periods.
For post-9/11 veterans, burn pit and airborne hazard exposure has been recognized as a contributor to cardiac disease. While the PACT Act presumptive list for burn pit exposure focuses more on respiratory conditions and cancers, cardiac conditions can be pursued on a direct service connection basis with medical nexus evidence.
Coronary bypass surgery under DC 7017 gets an automatic 100 percent rating for a three-month period following surgery, then is re-evaluated. The same applies for percutaneous coronary interventions like stent placement. After the three-month period, the rating reverts to whatever is supported by current METs and ejection fraction data. This provides a period of compensated recovery while the veteran heals and the functional status stabilizes.
Myocardial infarction under DC 7006 likewise provides automatic 100 percent for three months after the event, then evaluates based on residual functional capacity. Many veterans are surprised that a heart attack does not translate into a permanent 100 percent rating. The VA recognizes that many people recover substantial function after an MI and rates based on ongoing capacity.
Evidence for a cardiac claim includes service treatment records, any documented in-service cardiac events or symptoms, DD-214 and deployment records to establish exposure to presumptive hazards, current medical records with cardiology consultations, stress test reports with specific MET values, echocardiogram reports with specific ejection fraction percentages, hospital discharge summaries for any cardiac events, and a medication list. If you are claiming the condition as secondary to hypertension or another service-connected condition, a nexus letter is essential.
The C&P exam for cardiac conditions will include a review of records, a cardiac history, and completion of the appropriate DBQ. If current stress test or echocardiogram data are not available, the examiner may order testing. Be specific about your functional limitations. If you get short of breath walking to the mailbox, say so. If you cannot climb a flight of stairs without resting, say so. These statements help ground the MET estimation in the reality of your daily life.
Secondary conditions downstream of cardiac disease include chronic kidney disease from reduced cardiac output, stroke from cardiac emboli, and depression and anxiety that commonly develop after a major cardiac event. Each can be pursued as a secondary claim with appropriate evidence.
The Claim Recon Rating Calculator models how a cardiac rating combines with hypertension, PTSD, diabetes, and other commonly co-occurring conditions, helping you see whether a cardiac claim moves you toward a meaningful threshold. The C&P Exam Simulator prepares you for the cardiac DBQ by walking through the MET questions and functional capacity assessment. The Secondary Condition Finder maps cardiac disease to its upstream contributors such as hypertension and Agent Orange exposure, and its downstream effects such as kidney disease and mood disorders. The Personal Statement Builder helps you translate your actual daily limitations into the MET framework examiners use.
