The answer is C. 70% or greater
Angina pectoris is defined as retrosternal chest discomfort, pressure, or tightness specifically due to myocardial ischemia. It is the cardinal symptom of coronary artery disease and can be triggered by anything that increases myocardial oxygen demand. Angina usually occurs when coronary artery stenosis is about 70% or greater. Angina is further classified as stable vs unstable (not relieved by rest or nitro, new-onset, or worsening). Nuclear stress testing is the most widely used test for the diagnosis of ischemic heart disease in those with symptoms of angina.
