Step 1
Which treatments for cardiovascular disease work by directly reducing blood pressure?
Answer
To determine which treatments directly reduce blood pressure, we analyze the methods of action presented in the table.
- Antiplatelets: These reduce the action of platelets, which primarily helps in preventing blood clots, but does not directly lower blood pressure.
- Beta blockers: These block the effects of adrenaline, which can result in a decrease in heart rate and lower blood pressure. Thus, they do directly reduce blood pressure.
- Nitrates: Nitrates widen blood vessels, which leads to lower blood pressure by reducing the resistance the heart has to work against. Therefore, they do directly lower blood pressure.
- Statins: Their main function is to reduce cholesterol levels in the blood, and they do not work to directly reduce blood pressure.
From this analysis, the only options that include treatments which directly lower blood pressure are:
- Beta blockers
- Nitrates
Therefore, the correct answer is B) Beta blockers and nitrates.
