Circulatory or cardiovascular system is one of the most important systems in the human body. It consists of the heart, the blood vessels and the blood. The heart is the vital organ that has the function to pump the fresh oxygenated blood rich in nutrients through the blood vessels to the different parts in the body. The blood vessels form a vast network throughout the body. They are comprised of arteries, arterioles, veins and capillaries. It is very important to maintain the circulatory system healthy, since there are many disorders or diseases that can affect it.
Atherosclerosis is the medical term for the blocked arteries. It is also well known under the names coronary artery heart disease and coronary artery disease, abbreviated CAD. This disease occurs when the fat materials, as well as cholesterol, accumulate on the walls of the arteries causing the narrowing or blocking of them. Thus, the blood flow is impaired and the heart does not receive enough amounts of the necessary blood. The medical term for the impairment of the blood flow through the blood vessels is ischemia.
Symptoms of blocked arteries
The plaque that builds up on the walls of the arteries usually accumulates itself over a long period of time. The most common symptoms of coronary artery disease are angina pectoris (which is a sharp pain that occurs in the chest), shortness of breath, a feeling of pressure or discomfort in the chest and a feeling of choking. Furthermore, the people who suffer from the blocked arteries may experience a heart attack when one part of the heart fails. Other symptoms of atherosclerosis include excessive sweating, nausea and vomiting, as well as cold and pale skin.
The coronary artery sclerosis is a very serious health condition. It should be treated immediately when discovered. Otherwise, it can lead to the death, which is why it is extremely important to pay attention to the most common causes of this condition, such as hypertension, high cholesterol levels, diabetes, stress and obesity.
Treatment for blocked arteries
First of all, the people with atherosclerosis should avoid smoking; they should eat healthy foods and exercise regularly. The doctors usually prescribe certain medications to treat this disorder, such as beta-blockers, calcium-channel blockers and nitrates, as well as thrombolytic medicines, ACE inhibitors, angiotensin-2, vasodilators and statins. In severe cases, a surgery is necessary to treat coronary artery disease. The two most common surgical procedures when the blocked arteries are in the question are coronary artery bypass and angioplasty or percutaneous transluminal coronary angioplasty.
