Which condition are ACE inhibitors commonly used to treat?

ACE inhibitors are commonly used to treat congestive heart failure (CHF) and hypertension. They work by inhibiting the angiotensin-converting enzyme, which plays a crucial role in the renin-angiotensin-aldosterone system. By blocking this enzyme, ACE inhibitors help to lower levels of angiotensin II, a potent vasoconstrictor, leading to vasodilation and subsequently reducing blood pressure. In the context of CHF, they alleviate symptoms by reducing preload and afterload on the heart, improving cardiac output and overall function. The dual action on both hypertension and CHF makes ACE inhibitors a pivotal medication in managing these conditions effectively.
