Insights

Beta-blockers like carvedilol are well-tolerated in elderly patients with chronic heart failure (CHF). This study shows 80% tolerability, suggesting older adults with CHF should not be denied carvedilol treatment.

Area of Science:

  • Cardiology
  • Geriatric Medicine
  • Pharmacology

Background:

  • Beta-blockers are guideline-recommended for chronic heart failure (CHF).
  • Tolerability concerns limit beta-blocker use in elderly CHF patients.
  • Carvedilol is a key beta-blocker for heart failure management.

Purpose of the Study:

  • To evaluate the tolerability of carvedilol in elderly patients (>70 years) with CHF.
  • To assess carvedilol's real-world effectiveness in a large, multinational cohort.
  • To identify predictors of carvedilol tolerability in older adults.

Main Methods:

  • Prospective, multinational evaluation of 1030 CHF patients aged >70 years.
  • Patients received carvedilol in everyday clinical practice.
  • Tolerability defined as adherence to carvedilol therapy for ≥3 months, with a dose of ≥6.25 mg twice daily at 6 months.

Main Results:

  • Overall carvedilol tolerability was 80% in elderly CHF patients.
  • Tolerability rates were 84.3% (70-75 years), 76.8% (76-80 years), and 76.8% (>80 years).
  • Advanced age, low diastolic blood pressure, reduced left ventricular ejection fraction (LVEF), obstructive airways disease, and diabetes predicted lower tolerability.

Conclusions:

  • Carvedilol is well-tolerated in this cohort of elderly patients with chronic heart failure.
  • Concerns about tolerability should not prevent the use of carvedilol in elderly CHF patients.
  • Real-world data support carvedilol's use in older populations with heart failure.

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation, vasodilation, and...

Drug Dosing: Geriatric Patients

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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

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...

Heart Failure Drugs: Inotropic Agents

Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
