D) Rest and intake of nitroglycerin relieve chest pain with angina but not with MI

Explanation:

Angina is a condition that causes severe pain in the chest area, caused by a lack of blood in the caridac muscle, whereas myocardial infarction, or heart attack, is the death of cells in a region of the heart muscle due to the formation of a clot that stops the blood flow suddenly and intensely and causes severe pain in the chest area. To know if a patient's chest pain is caused by myocardial infarction or angina, it is necessary for the patient to take nitroglycerin and rest, if after that the chest pains are relieved, the patient had angina; if the pain is not relieved, the patient had myocardial infarction.
