Study Notes
Aging
- The process of growing older that usually begins at birth.
- A complex combination of physiological, psychosocial, and environmental factors.
- Includes diverse changes across different age groups, affecting physical, mental, and emotional states.
### Internal Factors Associated with Aging
- Telomere shortening: Protective caps at the ends of chromosomes that shorten with age, contributing to cell aging.
- Cellular senescence (cell aging): Irreversible cell cycle arrest in response to stressors, leading to age-related illnesses like arthritis.
- Mitochondrial dysfunction: Deterioration of mitochondria, responsible for energy production, impacting cellular function.
- Accumulation of oxidative damage: Imbalance between production of reactive oxygen species (ROS) and the body's ability to neutralize them, resulting in cell aging and damage to DNA, RNA, and proteins.
- Epigenetic changes: Modifications that regulate gene expression without altering DNA sequence, influencing aging processes.
External Factors Associated with Aging
- Lifestyle: Includes dietary choices, exercise habits, smoking, and alcohol consumption.
- Environmental exposures: Factors like sun exposure, air pollution, and pesticides can accelerate aging.
- Socioeconomic factors: Financial status, access to healthcare, and support systems play a role in healthy aging.
Aging-Related Changes of the Cardiovascular System
- Vascular aging: Changes in blood vessels, affecting their structure and function.
- Atherosclerosis: Build-up of plaque within blood vessels, narrowing them and restricting blood flow.
- Atrial fibrillation: Irregular heart rhythm, increasing risk of cardiovascular diseases and stroke.
- Left ventricular hypertrophy: Enlargement of the left ventricle, associated with an increased risk of coronary artery disease.
Cardiovascular Disease (CHD) and Older Adults
- Older adults may experience CHD differently than younger individuals due to factors like neuropathies.
- Typical chest pain may not be present.
- Stable angina: Chest pain during activity, relieved by rest and medication.
- Unstable angina: Chest pain at rest, signifying a more serious condition requiring hospitalization.
- Myocardial infarction (MI): Heart attack, caused by the death of heart muscle tissue.
### Managing CHD in Older Adults
- Lifestyle modifications: Weight management, stress management, limiting caffeine, smoking cessation, and controlling hypertension.
- Medication: Use of drugs to control blood pressure, cholesterol, and prevent blood clots.
- Angioplasty: Procedure to widen narrowed arteries using a balloon catheter.
### Hypertension in Older Adults
- Non-pharmacological management: Weight loss, salt restriction, increased potassium intake, reduced alcohol intake, and regular exercise.
- Pharmacological management: Use of medications like diuretics, beta-blockers, ACE inhibitors, calcium channel blockers, angiotensin II receptor blockers, and vasodilators.
### Hypotension (Postural) in Older Adults
- A significant decline in blood pressure upon standing, often due to vasoactive medications.
- Causes: Increased intake of vasoactive medications, age-related changes in baroreflex response.
- Management: Getting out of bed slowly, elevating the head of the bed, maintaining adequate fluid intake, avoiding hot showers, exercising regularly, and using medication like fludrocortisone as prescribed.
Respiratory Disorders in Older Adults
- Respiratory efficiency declines with age: Changes in lung structure and function affect gas exchange.
- Decreased respiratory volumes and capacities: Lower lung volumes and forced expiratory volume.
- Changes that occur in aging: Stiffening of the chest wall, reduced lung elasticity, and decreased muscle strength.
- Greater capillary network and blood supply in lower lung: Despite decreased airflow, efficient oxygen delivery is still possible.
