The most common symptom is [[chest pain]] or discomfort that occurs regularly with activity, after eating, or at other predictable times; this phenomenon is termed stable [[angina]] and is associated with [[stenosis|narrowing]] of the [[artery|arteries]] of the [[heart]]. Angina also includes chest tightness, heaviness, pressure, numbness, fullness, or squeezing.<ref name="Cleveland Clinic">{{cite web |title=Coronary Artery Disease Symptoms: Types, Causes, Risks, Treatment |url=https://my.clevelandclinic.org/health/symptoms/16821-coronary-artery-disease-symptoms |website=Cleveland Clinic }}</ref> Angina that changes in intensity, character, or frequency is termed unstable. [[Unstable angina]] may precede [[myocardial infarction]]. In adults who go to the emergency department with an unclear cause of pain, about 30% have pain due to coronary artery disease.<ref>{{cite journal | vauthors = Kontos MC, Diercks DB, Kirk JD | title = Emergency department and office-based evaluation of patients with chest pain | journal = Mayo Clinic Proceedings | volume = 85 | issue = 3 | pages = 284–99 | date = March 2010 | pmid = 20194155 | pmc = 2843115 | doi = 10.4065/mcp.2009.0560 }}</ref> Angina, shortness of breath, sweating, nausea or vomiting, and lightheadedness are signs of a heart attack or myocardial infarction, and immediate emergency medical services are crucial.<ref name="Cleveland Clinic" />

With advanced disease, the narrowing of coronary arteries reduces the supply of oxygen-rich blood flowing to the heart, which becomes more pronounced during strenuous activities during which the heart beats faster and has an increased oxygen demand.<ref>{{Cite web|title=Coronary artery disease – Symptoms and causes|url=https://www.mayoclinic.org/diseases-conditions/coronary-artery-disease/symptoms-causes/syc-20350613|access-date=2020-06-27|website=Mayo Clinic|language=en}}</ref> For some, this causes severe symptoms, while others experience no symptoms at all.<ref name="HLB2014" />
