What is coronary arteries?
Coronary arteries (CAD), also known as coronary heart disease, is a condition in which coronary arteries are prevented by a lot of plaque. Plaque consists of cholesterol, fat, calcium and other materials. When plaque accumulates in blood vessels, atherosclerosis is called atherosclerosis in coronary arteries, it is called coronary arteries. Worldwide, CAD is the main cause of death.
The artery is a blood vessel that transports blood from the inner chambers of the heart, whether blood oxygenated blood into the body tissue or to lift oxygen from the lungs. Koronární tepny probíhají podél povrchu srdce a krmí okysličenou krev do tkáně srdce. These blood vessels are elastic and make it easy to pass blood if they are without restrictions. However, when the plaque accumulates, the blood flow can be blocked, which can cause angina or heart attack.
Angina's chest and pressure pain, this occurs when a partial block of blood vessels prevents sufficient oxygenated bloode into the heart muscle. The arm, neck and jaw can also be experienced. The heart attack occurs when coronary arteries are completely blocked, causing part of the heart muscle to suffer damage or die. The heart attack is represented with shortness of breath, nausea and pain and pressure in the chest, as well as the neck, arms, back and stomach.
Often, infarction is filmed due to a plaque bearing, which causes clotting known as the platelet to the site in an effort to repair the container. This causes another obstacle to the container. Coronary arteries can also cause arrhythmia, irregular beating of the heart or heart failure.
blood vessel damage is considered to be the main contributor to the development of coronary arteries. Normal causes of Sel is smoking, high cholesterol, diabetes, high levels of stress and radiation. Cell waste, cholesterol and fats then hold damaged containers and createPlak.
Several factors can increase the chances of coronary arteries, including sex, age, obesity, high blood pressure and family history. Males more often develop coronary arteries than women and older patients are much more susceptible to CAD development than younger patients. In particular, the family history increases the risk of the patient if the patient's family member has developed a CAD before sixty. It is important to realize these risk factors, as CAD can be undiagnosed for a long time and unnoticed.
Coronary arteries can be treated with lifestyle changes, medicines, surgery or a combination of these approaches. Doctors usually recommend reducing stress, healthy diet, exercise, weight loss and smoking cessation if possible. The doctor may also prescribe north of drug types, including drugs that modify the amount of cholesterol in the blood, resulting in a lower amount of poor cholesterol or an increase in good cholesterol. Other medicines include ŘBlood edges such as aspirin, beta blockers that reduce the need for oxygen, nitroglycerin tablets, enzyme -converting angiotensin (ACE) inhibitors and calcium channel blockers.
In more serious cases, the physician may have to try surgical approach such as angioplasty or obset coronary artery. During the angioplasty, the surgeon puts the balloon over the catheter into a blocked artery, inflates the balloon to compress the plaque and expand the container and often implants the stent to hold an open container. During the surgery of the coronary artery, the surgeon cleaves the container from another part of the body, usually from the arm, leg or chest to flow blood around the blocked artery.
