Varenicline is considered safe for patients with cardiovascular illness.

• A. True
• B. False
• C. Only mild disease
• D. Not studied

Answer: (A)

The main idea here is the safety of varenicline for people with cardiovascular disease. Evidence from randomized trials and larger analyses shows that varenicline does not increase the risk of major cardiovascular events compared with other quit aids or placebo. In people with stable cardiovascular illness, studies such as large head-to-head and meta-analytic analyses have found similar rates of cardiovascular problems when using varenicline versus alternatives like nicotine replacement therapy or no pharmacotherapy. This supports its use as a safe option for helping patients quit smoking, provided the cardiovascular condition is stable and monitored.

Why the other possibilities don’t fit: the idea that it’s not studied isn’t accurate given the substantial research on cardiovascular safety; the notion that safety is limited only to mild disease isn’t supported by the breadth of stable-CVD data; and the claim that it’s not safe would contradict the accumulated trial evidence showing no increased cardiovascular risk.
