In most cases, this is caused by a brief decrease in the supply of blood to the brain, which can be caused by a change in blood pressure, a lack of food, or more serious reasons such as heart illness or neurologic disease, among others. People of any age can experience fainting, although older people are more likely to be suffering from a significant underlying reason.
Arteriosclerosis (hardening of the arteries) is a condition that affects many people. Because of fatty plaque deposits inside the blood vessels, the blood arteries constrict and eventually become completely blocked. The condition known as congestive heart failure is quite frequent among elderly persons.
This has an effect on the flow of blood through the artery and can raise the likelihood of major diseases such as a stroke or heart attack occurring as a result. It is a slow-progressing disorder that may manifest itself early in life, but which frequently manifests itself in the elderly and results in the most severe problems.
The heart and blood arteries alter as a result of aging. Blood vessels are the points at which oxygen and nutrients are delivered to the tissues and carbon dioxide and waste products are returned to the blood vessel from the tissues. Later, the vessels begin to group together to form larger and larger veins, which are responsible for returning blood to the heart.
Hypertension, often known as high blood pressure, is another prevalent risk factor in the elderly. In addition to increasing strain on the heart, high blood pressure may also contribute to the development of coronary heart disease. The blood pressure of your loved one should be monitored, and efforts taken to keep it at a lower level should be considered.
Because of their high lumen blood pressure and thicker walls, arteries are more resistant to collapse than veins, which are prone to collapse because of their low internal pressure. Certain diseases, however, can cause arteries to burst and collapse. For example, the intramyocardial coronary arteries collapse during the contraction of the left ventricle.
When a rip forms in a blood vessel in the heart, it’s known as spontaneous coronary artery dissection (SCAD). This is a life-threatening disorder that requires immediate medical attention. Sudden cardiac arrest (SCAD) can occur when blood supply to the heart is slowed or blocked, leading to a heart attack, heart rhythm disorders (arrhythmias), or death.
A frequent aging alteration is increased stiffness of the major arteries, which is referred to as arteriosclerosis (ahr-teer-oskluh-roh-sis) or hardening of the arteries (pronounced ″ahr-teer-oskluhrohsis″). Eventually, this results in high blood pressure (hypertension), which becomes more frequent as we become older.
Every effort should be made by health care practitioners to enable the injured artery to heal on its own whenever feasible. Some patients may find that drugs alleviate the symptoms of SCAD, and it may be feasible to manage the condition solely with pharmaceuticals in these cases. If chest discomfort or other symptoms continue, it is possible that more treatments will be required.
The exact etiology of SCAD remains a mystery.Diabetes-related coronary artery disease (SCAD) mostly affects young, healthy persons who have few or no risk factors for heart disease, such as diabetes, smoking, high cholesterol, or obesity.The following are some of the most common risk factors and probable triggers for SCAD: The fact that you are female — SCAD affects women at a higher rate than males.
Carotid artery dissection is characterized by a severe headache, as well as discomfort in the face and neck, among other signs and symptoms.You may also experience vision issues, including the possibility of losing your sight totally for a period of time, although this should subside.Other signs and symptoms include migraine headaches and a drooping eyelid, which can be quite uncomfortable.
Despite recent advancements in the treatment of congestive heart failure, experts say the outlook for those suffering from the condition remains gloomy, with an average life expectancy of fewer than five years for around half of those suffering from the disease. Those suffering from severe kinds of heart failure die at a rate of approximately 90 percent within a year.
According to the World Health Organization, atherosclerosis is a serious public health concern that accounts for at least 30% of all fatalities worldwide each year (Figure 51-1 ). It is associated with a bad prognosis and dramatically shortens the life expectancy of patients over the age of 60 by 8–12 years, depending on the vascular event that has taken place.
Each of the five key steps in atherogenesis can be broken down into a single step: 1) endothelial dysfunction, 2) formation of an inflammatory lipid layer or fatty streak within the intima, 3) migration of leukocytes and smooth muscle cells into the vessel wall, 4) foam cell formation, and 5) degradation of the extracellular matrix.
