Which statement best describes the difference between angina and myocardial infarction in the field?

• A. Angina lasts longer than MI and is not relieved by rest
• B. Angina is chest pressure that improves with rest; MI is prolonged and may include diaphoresis, nausea, or SOB
• C. MI symptoms always include vomiting
• D. Angina is always accompanied by a seizure

Answer: (B)

The main idea is how angina and myocardial infarction differ in duration and response to rest, along with the presence of broader symptoms in a possible heart attack. Angina is chest pressure or discomfort caused by temporary, reversible ischemia that typically improves with rest or relief measures. Myocardial infarction is an actual heart muscle injury from a blocked artery and often lasts longer, persisting despite rest and may be accompanied by systemic signs such as sweating (diaphoresis), nausea, and shortness of breath. That’s why this choice is best: it captures the two classic patterns—angina as chest pressure that improves with rest, and MI as prolonged chest pain with additional symptoms like diaphoresis, nausea, or shortness of breath. The other statements are not as accurate: angina does not usually last longer than MI nor remain unrelieved by rest; MI does not require vomiting to be present; and angina is not defined by seizures. In the field, recognizing this distinction helps determine whether to provide supportive care and escalate to emergency assessment for potential heart attack.
