How does angiotensin-converting enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs) improve the cardiac function of a client diagnosed with heart failure?They increase the heart rate and decrease the force of the contractions. They increase the resistance to the (L) ventricular ejection (afterload). They promote relaxing of the arterioles and arterial vasodilation. They help prevent sodium and water retention by blocking aldosterone. They improve the heart's stroke volume, thus improve cardiac output.
