Final answer:
The claim that beta-blockers are not contraindicated in patients with Peripheral Arterial Disease (PAD) is false. These medications block beta-receptors, which can lead to reduced blood flow to the extremities and may worsen PAD symptoms.
Step-by-step explanation:
The statement that beta-blockers are not contraindicated in patients with Peripheral Arterial Disease (PAD) is false. Beta-blockers are used to treat cardiovascular diseases because they block beta-receptors that are associated with vasoconstriction and cardioacceleration. Specifically, they improve cardiac function by allowing blood vessels to dilate and by keeping heart rate from increasing too much. Common types include metoprolol, which specifically blocks the beta-1 receptor, and propranolol, which blocks beta-receptors nonspecifically. However, due to their effect on reducing heart rate and the potential decrease in blood flow to the extremities, there are concerns about using beta-blockers in patients with PAD, as they may exacerbate symptoms of claudication.
