Insights

Elderly patients undergoing percutaneous coronary intervention (PCI) face higher complication risks. However, despite an increase in elderly PCI procedures, complication rates have remained stable over time.

Area of Science:

  • Cardiology
  • Geriatric Medicine
  • Interventional Cardiology

Background:

  • The elderly population is growing, with a high prevalence of coronary heart disease.
  • Percutaneous coronary intervention (PCI) is a primary revascularization method for older adults.
  • Investigating age-related risks and temporal trends in PCI complications is crucial.

Purpose of the Study:

  • To assess if periprocedural complication risk is higher in elderly patients (age ≥75) undergoing PCI.
  • To determine if this risk has changed over time.
  • To analyze trends in PCI utilization among the elderly.

Main Methods:

  • Retrospective cohort study using the Scottish Coronary Revascularization Register (2000-2007).
  • Inclusion of 31,758 patients undergoing non-emergency PCI.
  • Comparison of complication rates between elderly and younger patients, and analysis of trends over the study period.

Main Results:

  • PCI procedures in elderly patients increased significantly from 8.7% to 13.9% between 2000 and 2007.
  • Elderly patients presented with more complex conditions: multivessel disease, comorbidities, and prior cardiac events.
  • The 30-day major adverse cardiovascular event rate was higher in the elderly (4.5%) compared to younger patients (2.7%).

Conclusions:

  • Elderly patients undergoing PCI have a higher risk of periprocedural complications.
  • Despite an increasing proportion of elderly patients receiving PCI, the risk of complications has not significantly changed over time.
  • This suggests that current PCI practices are managing the increased complexity in elderly patients effectively.

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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
