What effect do ACE inhibitors have on morbidity and mortality associated with heart failure?

The choice indicating that ACE inhibitors decrease morbidity and mortality rates in heart failure patients is supported by extensive clinical research. ACE inhibitors, such as enalapril and lisinopril, work by inhibiting the angiotensin-converting enzyme, leading to vasodilation, reduced blood pressure, and decreased strain on the heart.

In patients with heart failure, the body’s compensatory mechanisms often lead to increased sympathetic tone and activation of the renin-angiotensin-aldosterone system (RAAS), contributing to further heart failure progression. ACE inhibitors counteract these effects, improving hemodynamics and reducing fluid retention, which can alleviate symptoms like shortness of breath and fatigue.

Moreover, studies have demonstrated that the use of ACE inhibitors is associated with improved outcomes, including reduced hospitalizations (lower morbidity) and a lower risk of death (lower mortality) in both systolic and diastolic heart failure cases. This positive impact on heart failure management is well-documented in guidelines, providing strong evidence that they play a critical role in enhancing the quality of life and longevity in affected patients.
