Body system: Cardiovascular SystemRegulation: 38 CFR § 4.104DBQ: DBQ CARDIO Heart
A myocardial infarction (heart attack) is the death of heart muscle tissue caused by blocked blood flow, usually from a coronary artery occluded by an atherosclerotic plaque rupture and thrombus. The VA rates this condition at 100% during the MI and for THREE MONTHS following, provided the MI is confirmed by laboratory tests (typically cardiac troponin elevation, characteristic ECG changes, or cardiac imaging). After that 3-month window, the rating transitions to the General Rating Formula for Diseases of the Heart (38 CFR § 4.104), based on the MET workload at which heart failure symptoms appear and any cardiac structural changes from the infarction. If continuous cardiac medication is required for control, a minimum 10% rating applies.
Rating levels
- 100% — You qualify for 100% during a myocardial infarction (heart attack) AND for THREE MONTHS following the infarction, provided the MI is confirmed by laboratory tests (cardiac troponin elevation, characteristic ECG changes, or cardiac imaging). The 100% rating covers the acute event plus the immediate recovery period. After that 3-month window, the rating transitions to the General Rating Formula for Diseases of the Heart tiers below, based on workload tolerance and any cardiac structural changes that resulted from the MI.
- 100% — You qualify for 100% under the General Rating Formula for Diseases of the Heart if exercise testing (or a clinically equivalent assessment) shows that a workload of 3.0 METs or less brings on heart failure symptoms. 3.0 METs is roughly equivalent to slow walking on a level surface, so this rating means even minimal activity provokes symptoms.
- 60% — You qualify for 60% if exercise testing shows that a workload of 3.1 to 5.0 METs brings on heart failure symptoms (dyspnea, fatigue, angina, dizziness, or syncope). The 3-5 MET range covers activities like light housework, slow walking, and dressing.
- 30% — You qualify for 30% if a workload of 5.1 to 7.0 METs brings on heart failure symptoms, OR if you have echocardiographic evidence of cardiac hypertrophy (thickening of the heart muscle) or dilatation (enlargement of the heart chambers), confirmed by echocardiogram, Doppler echocardiogram, MUGA scan, or cardiac MRI. The 5-7 MET range covers brisk walking, climbing stairs at a normal pace, and light cycling.
- 10% — You qualify for 10% if a workload of 7.1 to 10.0 METs brings on heart failure symptoms, OR if you require continuous medication (such as beta blockers, ACE inhibitors, statins, anti-anginal medications, or other cardiac drugs) to keep symptoms under control. The 7-10 MET range covers heavier exertion like jogging, vigorous cycling, or carrying heavy loads upstairs.
