What is Established Cardiovascular Disease
Established cardiovascular disease is defined as a history of acute coronary syndromes, myocardial infarction, stable or unstable angina, coronary or other arterial revascularization, stroke, transient ischemic attack, or peripheral arterial disease presumed to be of atherosclerotic origin 1.
Clinical Definition from Guidelines
The 2013 ACC/AHA cholesterol guidelines provide the authoritative definition used for identifying patients who require secondary prevention therapy. This definition is based on the inclusion criteria from major secondary-prevention statin randomized controlled trials 1.
Specific Conditions Included:
Coronary artery disease manifestations:
- Acute coronary syndromes
- History of myocardial infarction (MI)
- Stable angina
- Unstable angina
- Coronary revascularization (PCI, CABG, or other arterial revascularization)
Cerebrovascular disease:
- Stroke (ischemic or hemorrhagic when atherosclerotic)
- Transient ischemic attack (TIA)
Peripheral vascular disease:
- Peripheral arterial disease presumed to be of atherosclerotic origin
Clinical Significance
Patients with established cardiovascular disease constitute the highest-risk group for recurrent atherosclerotic cardiovascular (ASCVD) events and require the most intensive preventive therapy 1. This designation automatically qualifies patients for:
- High-intensity statin therapy without need for risk calculation
- Aggressive management of all cardiovascular risk factors
- Secondary prevention strategies
Important Distinction
The presence of established cardiovascular disease means that 10-year ASCVD risk estimation is not appropriate or necessary for these patients 1. They are already in the highest-risk category and should receive maximal evidence-based therapy regardless of calculated risk scores.
Recent observational data confirms that patients with pre-existing cardiovascular disease experience significantly higher mortality when facing acute illnesses, with increased risk of myocardial injury 2, reinforcing the importance of identifying and aggressively treating this population.
