    Study Notes

    Cardiovascular Changes in Older Adults

    • Structural changes in the heart and blood vessels lead to higher blood pressure and decreased blood circulation.
    • Endothelium thickens, causing blood vessels to constrict.
    • Inner vessel layers lose elasticity.
    • Pacemaker cells in the sinoatrial node decrease, lowering heart rate.
    • Aorta thickens, stiffens, and becomes less flexible, likely due to connective tissue changes.
    • Arteries thicken and stiffen, blood pressure often increases moderately.
    • Baroreceptors become less sensitive, potentially causing orthostatic hypotension.
    • Vein walls thicken, valves stiffen and become incompetent, leading to varicose veins.
    • Valves in the heart stiffen, leading to blood regurgitation, edema, and clots.
    • Blood vessels lose elasticity, leading to increased vessel diameter and rigidity.
    • Progressive degeneration of cardiac structures happens with age, including fibrotic changes and amyloid infiltration.
    • Left ventricular contractility is reduced, lowering heart's pumping capacity.
    • Persistent inflammation contributes to endothelial dysfunction, arterial stiffness, and atherosclerosis, potentially driving increased pro-inflammatory cytokines and oxidative stress.
    • Cardiac structures with the largest impact are the heart’s left ventricular wall and its contractility.
    • The ability of the heart to pump is reduced.
    • Cardiac output and aerobic capacity decrease with age.
    • The age-related changes impact the structure and function of the cardiac valves (aortic semilunar, mitral, tricuspid, and pulmonary). Stiffening leading to dysfunction can cause regurgitation, edema, and clots.
    • Angina, or chest pain - can be sudden or complete oxygen blockage in heart muscle; pain lasting more than 10 minutes requires immediate help.

    Blood Volume

    • Blood volume decreases with aging due to reduced body water in the bloodstream.
    • Red blood cell production slows, affecting response to blood loss or anemia.
    • White blood cell function (neutrophils) diminishes, impacting infection resistance.
    • Total body water decreases as a consequence of normal aging.

    Heart Rate

    • Maximal heart rate decreases due to autonomic nervous system changes and reduced pacemaker cells.
    • Stroke volume might increase slightly at rest.
    • Heart rate increases with emotional stress, illness, injury or exertion.

    Blood Pressure

    • Moderate blood pressure increase is typical in older adults, related to vascular changes and increased vascular resistance.
    • Baroreceptors become less sensitive, impacting pressure regulation.
    • Orthostatic hypotension is a possible outcome from baroreceptor insensitivity.

    Other Considerations

    • Daily Hydrochlorothiazide (12.5 mg) may be prescribed for elderly patients with isolated systolic hypertension.
    • Heart function declines, including kidney function.
    • Murmurs are common in older adults related to valve thickening.
    • Skin might pale, cool, and clammy; capillary refill time might increase.
    • Chronic diseases like atherosclerosis, hypertension, and ischemia heart disease are age-related and are common in older adults - influenced by factors like poor diet, sedentary lifestyle and stress.
    • Lifestyle modifications, like exercise and balanced diet, are crucial to maintain cardiovascular health in old age.
    • Emotional stress, illness, or injury can increase heart workload and heart rate.
    • The autonomic nervous system is affected with age, resulting in a reduced maximum heart rate.
    • Stroke volume shows little change in resting adults, but is affected by exertion.
    • Chronic conditions, like cardiovascular disease, are potentially connected to inflammation and related issues, like atherosclerosis.
    • Proper nutrition is important for managing certain conditions, including a DASH diet.
    • Low sodium intake, cholesterol and saturated fat intake are crucial for managing hypertension.
    • Moderate exercise helps maintain cardiovascular health.
    • Smoking cessation is important to prevent damage to blood vessels.
    • Management of hypertension and diabetes are crucial.
    • Atherosclerosis and hypertension are common in older adults, potentially due to poor diet, sedentary lifestyle, and/or stress.
