What does the acronym ACE stand for in medical terms?

The acronym ACE stands for Angiotensin-converting enzyme. This is a crucial enzyme in the body that plays a significant role in the renin-angiotensin system, which regulates blood pressure and fluid balance. Specifically, ACE converts angiotensin I, an inactive precursor, into angiotensin II, a potent vasoconstrictor that raises blood pressure and stimulates the release of aldosterone, which in turn promotes sodium and water retention by the kidneys. Understanding the function of ACE is essential in medical practice, particularly in the treatment of hypertension and heart failure, where ACE inhibitors are commonly prescribed to help manage these conditions.
