The classic manifestation of ischemia is angina, which is usually described as a heavy chest pressure or squeezing, a burning feeling, or difficulty breathing

Silent STEMI 1. Nonfatal STEMI can be unrecognized by the patient and discovered only on subsequent routine electrocardiographic or postmortem examinations. 2. Of these unrecognized infarctions, approximately half are truly silent. 3. The other half of patients can recall an event characterized by symptoms compatible with acute infarction. 4. Unrecognized or silent infarction occurs more commonly in patients without antecedent angina pectoris and in patients with diabetes and hypertension. Feringa HH, Karagiannis SE, et al.

Pain patterns with myocardial ischemia
Atypical descriptions of chest pain Pleuritic pain (i.e., sharp or knifelike pain brought on by respiratory movements or cough) Primary or sole location of discomfort in the middle or lower abdominal region Pain that may be localized at the tip of one finger, particularly over the left ventricular apex Pain reproduced with movement or palpation of the chest wall or arms Constant pain that persists for many hours Very brief episodes of pain that last a few seconds or less Pain that radiates into the lower extremities Anderson JL, et al. ACC/AHA Guidelines for the management of UA/NSTEMI. Circulation 116:e148, 2007
Atypical descriptions epigastric location When the pain of STEMI is epigastric in location and is associated with nausea and vomiting, the clinical picture can easily be confused with that of acute cholecystitis, gastritis, or peptic ulcer. More commonly in patients with inferior STEMI than in those with anterior STEMI. Occasionally, a patient complains of diarrhea or a violent urge to defecate during the acute phase of STEMI.
Atypical presentations of STEMI other symptoms 1. heart failure (i.e., dyspnea without pain beginning de novo or worsening of established failure) 2. CNS manifestations, resembling those of stroke, secondary to a sharp reduction in cardiac output in a patient with cerebral arteriosclerosis 3. apprehension and nervousness 4. sudden mania or psychosis 5. Syncope 6. overwhelming weakness 7. diaphoresis 8. acute indigestion and 9. peripheral embolization. Anderson JL, et al. ACC/AHA Guidelines for the management of UA/NSTEMI. Circulation 116:e148, 2007

Atypical symptoms or ECG findings of STEMI Take home messages STEMI occurs in patients with atypical symptoms or ECG findings with sufficient frequency. No single factor should be used to exclude the diagnosis of ACS. In particular, women, older persons, and individuals with diabetes may be more likely to report atypical symptoms. These patients represent a high-risk group. Emergency department and coronary care personnel need to have an increased awareness of this patient cohort, who should be provided with improved early diagnosis and better treatment options to reduce their significant morbidity and mortality.
