Insights

Elderly heart failure patients often receive lower doses of angiotensin-converting enzyme (ACE) inhibitors, increasing their risk for clinical events. Optimizing ACE inhibitor therapy in older adults is crucial for improved heart failure outcomes.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Angiotensin-converting enzyme (ACE) inhibitors are proven to reduce mortality in heart failure patients.
  • Despite proven benefits, ACE inhibitor utilization patterns require further investigation.

Purpose of the Study:

  • To compare ACE inhibitor prescribing patterns, specifically target doses, between elderly and nonelderly heart failure patients.
  • To identify potential disparities in ACE inhibitor utilization and their impact on clinical outcomes in different age groups.

Main Methods:

  • Prospective evaluation of 43 ambulatory heart failure patients.
  • Assessment of prescribed ACE inhibitor doses and clinical events via patient interviews and medical records.
  • Follow-up at 3 months to document clinical events.

Main Results:

  • Elderly patients were significantly less likely to receive target ACE inhibitor doses (21.4% vs. 68.8%, p=0.0136).
  • Elderly patients experienced more clinical events compared to nonelderly patients (11 vs. 4, p=0.0074).
  • A trend indicated higher event rates in elderly patients not at target ACE inhibitor doses.

Conclusions:

  • Lower ACE inhibitor doses in elderly heart failure patients may be associated with an increased risk of clinical events.
  • These findings highlight a potential gap in optimizing ACE inhibitor therapy for elderly heart failure populations.

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
