Which of the following conditions results from chronic NSAID use?

Chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs) has been associated with several adverse health outcomes, making the selection "All of the above" the most accurate choice.

Gastrointestinal ulcers are a well-documented side effect of prolonged NSAID use. These medications can disrupt the protective mucosal barrier of the gastrointestinal tract, leading to irritation, ulceration, and potentially serious complications such as gastrointestinal bleeding.

Increased cardiovascular events are also a risk associated with long-term NSAID use. Certain NSAIDs have been shown to elevate blood pressure and increase the risk of heart attack and stroke, particularly in patients with preexisting cardiovascular conditions.

Renal damage is another significant concern linked to chronic NSAID use. These medications can impair renal function by affecting renal blood flow and glomerular filtration rate, especially in individuals with existing kidney issues or dehydration.

Considering these multiple risks—gastrointestinal ulcers, increased cardiovascular events, and renal damage—it's clear that prolonged NSAID use can lead to a combination of serious health problems. Therefore, the best answer, which encompasses all these potential complications, is indeed "All of the above."
