Summary
Vascular age, reflecting blood vessel health, can be influenced by treatments. Fixed combinations like atorvastatin and perindopril improve patient compliance for managing vascular aging.
Area of Science:
- Cardiovascular Science
- Gerontology
- Pharmacology
Background:
- Vascular age, distinct from chronological age, reflects the health of blood vessels.
- Vascular aging begins in childhood, involving arterial stiffening (arteriosclerosis) and plaque buildup (atherosclerosis).
- These aging processes contribute to ischemia and atherothrombosis.
Purpose of the Study:
- To explore the concept of vascular age and its clinical implications.
- To investigate methods for monitoring arterial aging processes.
- To assess the potential for influencing vascular age through pharmacological interventions.
Main Methods:
- Pulse wave velocity (PWV) measurement for arteriosclerosis.
- Non-invasive imaging (ultrasound, CT angiography) for atherosclerosis.
- Review of evidence for pharmacological treatments affecting vascular aging.
Main Results:
- Arteriosclerosis can be monitored via PWV.
- Atherosclerosis can be assessed using non-invasive imaging.
- Hypolipidemic drugs and ACE inhibitors show potential in influencing vascular aging.
Conclusions:
- Vascular age is a significant clinical parameter that can be modified.
- Treatments like atorvastatin and perindopril can impact vascular aging.
- Fixed-dose combinations enhance patient compliance for managing vascular health.

01:19The Effect of Aging on Tissues
3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
147
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...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
147
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...

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...
