A45-year-old man had coronary artery stents placed 2 days ago. today, he is in severe distress and is reporting "crushing" chest discomfort. he is pale, diaphoretic, and cool to the touch. his radial pulse is very weak, blood pressure is 64/40 mm hg, respiratory rate is 28 breaths/min, and oxygen saturation is 89% on room air. when applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. which condition led to cardiac arrest?

The given case is a result of acute coronary syndrome.

Explanation:

Acute coronary syndrome is a term given to the three kinds of coronary artery disorder, which are related to the sudden splitting of plaque within the coronary artery. The condition generally results from the accumulation of plaques or fatty deposits in and on the walls of the coronary arteries, that is the blood vessels that transmit nutrients and oxygen to the muscles of the heart. When the deposit of the plaque splits or ruptures, the formation of blood clot takes place. This clot prevents the flow of the blood to the muscles of the heart.
