What therapeutic effects do ACE inhibitors provide?

• A. They improve respiratory function and decrease coughing
• B. They relax blood vessels, lower blood pressure, and improve heart function
• C. They enhance kidney filtration and increase urine output
• D. They reduce blood sugar levels and improve insulin sensitivity

Answer: (B)

ACE inhibitors, or Angiotensin-Converting Enzyme inhibitors, primarily work by inhibiting the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This inhibition leads to relaxation of blood vessels, allowing them to widen. When blood vessels are relaxed, it results in a reduction in blood pressure, which is one of the main therapeutic effects of ACE inhibitors. Additionally, by decreasing peripheral vascular resistance, they improve heart function by allowing the heart to pump more efficiently, especially in patients with heart failure or left ventricular dysfunction. These medications are also beneficial in protecting the kidneys, especially in patients with hypertension or diabetes, as they help reduce the progression of kidney disease by lowering intraglomerular pressure. However, their primary and most significant therapeutic effects focus on vascular relaxation, blood pressure reduction, and enhancement of heart function. The other options pertain to different therapeutic classes or effects not specifically associated with ACE inhibitors, which clarifies why those responses do not provide correct answers. Understanding the specific actions of ACE inhibitors is key to recognizing their role in managing cardiovascular conditions.
