Atherosclerosis: How to detect deadly changes in vessels?
0
atherosclerosis is a slowly progressive change in arteries due to the loss of elasticity in their fabrics and narrowing. Atherosclerosis is the cause of deadly cardiovascular disease such as heart attack and stroke.
Healthy arteries have the ability to respond elastic to the amount of blood transmitted with each pulse wave: the vascular walls then expand, then reduce again. When the vascular tissue loses its elasticity, the arteries lose the ability to expand and narrow in response to blood flow. As a result, the amount of blood produced by the arteries decreases, and the organs are worse provided with oxygen and nutrients. Such a loss of elasticity in the vessels and arteries, which is one of the signs of atherosclerosis is known as calcification.
to atherosclerosis leads plaques. These deposits are also called plaques.
Plaques can occur and accumulate in different areas of the arterial system, capable of affecting both the smallest blood vessels and large, up to the main arteries. Plaques in the arteries are one of the causes of ischemic heart disease and occlusal peripheral arteries, as well as known as intermittent lameness.
atherosclerosis for a longAtherosclerosis develops slowly and therefore remains unnoticed for a long time. Only when, for example, the blood flow in the coronary vessels decreases half, painful symptoms, including angina.
As the atherosclerosis of the plaque in some places progresses can be increased, and as a result, the conductivity of vessels is quite low. These narrow places are called stenoses. If such a narrow place gets a blood clot that is formed from plaques that have peeling and migrating with blood flow, there is a likelihood of developing occlusion of vessels. In this violation, blood can no longer pass through the narrowed vessel, and its flow into the tissue is completely stopped. The fabric as a result begins to die. The closure of the artery that supplies the brain leads to the development of stroke. Scientists emphasize that atherosclerosis is the trigger mechanism of the main causes of death in Western industrialized countries.
How to understand what is atherosclerosis? According to doctors, it can take many years before a person notice the symptoms of progressive vascular changes. Atherosclerosis remains asymptomatic for a long time and is manifested only by secondary diseases. Atherosclerosis can be spoken of:
- ischemic heart disease with angina or peripheral artery disease;
- failures caused by a lack of oxygen in the heart and brain: reduction of tone and performance, dizziness, memory impairment;Feeling in the legs: Due to the narrowing of the vessels of the feet, tingling, cold, sharp and severe pain can be felt, which makes you stop when walking;
- Increased pressure: hypertension is a simultaneously trigger mechanism and a symptom of atherosclerosis. Part of the aging process, but smoking and other bad habits can make it premature and life -threatening. Oily and very salty foods, lack of normal physical activity contribute to the formation of deposits on the inner walls of the vessel. The health of the vessels is also significantly affected by stress and metabolic diseases: obesity, diabetes. The latter does not mean that you need to come up with the best sports results. It has been shown that just regular walks are quite effective to reduce the risk of cardiovascular disease caused by atherosclerosis.
