Final answer:
ACE inhibitors do not directly lower heart rate but instead focus on reducing blood pressure by inhibiting the conversion of angiotensin I to angiotensin II.
Step-by-step explanation:
True, ACE inhibitors do not directly lower the heart rate (HR). ACE inhibitors work by blocking the conversion of angiotensin I to angiotensin II, a compound that narrows blood vessels and increases blood pressure. By preventing this conversion, ACE inhibitors help to lower blood pressure.
But they do not have the same effect on heart rate as ß-blockers, on the other hand, work by blocking the effects of adrenaline on β-1 receptors, which are found in the heart. This action slows the heart rate and is used as a treatment for hypertension.
It is crucial not to confuse these two classes of drugs: while ß-blockers can lead to decreased HR and potentially bradycardia, ACE inhibitors primarily affect blood pressure without the same direct impact on HR.
