b. nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Two conditions related to cardiac compromise are angina pectoris and myocardial infarction. In comparing the two, remember that nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Explanation;
-Angina pectoris is the chest pain or discomfort due to coronary heart disease. It occurs when the heart does not get enough blood, due to blockage or narrowing of one or more heart's arteries.
-Myocardial infarction occurs when there is decreased blood flow or stoppage to a part of the heart, resulting to the heart muscle damage.
