A 45-year-old man undergoes cardiac catheterization because of a 1-year history of chest pain with exertion. During the procedure, acetylcholine is infused into a coronary artery, and it causes vasoconstriction. The dysfunctional endothelial cells from this artery are more likely than normal endothelial cells to do which of the following? A) Express intercellular adhesion molecules B) Inhibit platelet aggregation C) Inhibit thrombosis D) Produce nitric oxide E) Produce prostacyclin (PGI2)

Step 1
The patient has a history of chest pain with exertion, which suggests angina pectoris due to coronary artery disease (CAD). CAD is typically caused by atherosclerosis, a condition characterized by the buildup of plaques in the arterial walls. Show more…

A 40-year-old man is admitted to the hospital because of paroxysmal supraventricular tachycardia (PSVT). An intravenous bolus of adenosine is administered, and the PSVT resolves. The effectiveness of this treatment at the atrioventricular node is most likely due to an increase in which of the following? A) Calcium conductance B) CAMP synthesis C) cGMP synthesis D) Chloride conductance E) Nitric oxide synthesis F) Potassium conductance G) Prostaglandin synthesis H) Sodium conductance
