Stable angina is characterized by which of the following?

Stable angina is driven by predictable increases in myocardial oxygen demand that provoke chest pain, typically with exertion or stress, and is relieved by rest or nitro. Emotions can trigger sympathetic activation, increasing heart rate and contractility, which raises demand and can reproduce angina in someone with fixed coronary obstruction. This makes an emotional-stress trigger a hallmark of the stable pattern among the given options. The other scenarios describe patterns more consistent with unstable angina or ACS: pain at rest suggests unstable angina/MI; no predictable pattern points to an unstable presentation; and needing urgent PCI is reserved for ACS or high-risk unstable symptoms, not typical stable angina managed medically.
