CAC: coronary artery calcium; CAD: coronary artery disease; CVD: cardiovascular disease; MACE: major adverse cardiovascular events; MET: metabolic equivalent of task.
* Individuals with CAC >1000 are at high risk for MACE and may have event rates similar to those with stable CAD.
¶ Patients with CVD who usually fall into the low-risk category include those with class I to II angina, class I to II heart failure, mild valvular heart disease, and atrial fibrillation/flutter with normal rate.
Δ Patients with CVD who usually fall into the high-risk category include those with class III to IV angina, class III to IV heart failure, and severe valvular heart disease.
