Heart muscle, like any other organ or tissue found in the body, needs oxygen-rich blood in order to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. The aorta, our body's main blood supplier, is divided into two main coronary blood vessels called arteries. And the coronary arteries, in turn, branch into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.
Aorta, carotid artery, femoral artery
Coronary arteries are the arteries that supply blood to the heart muscle, which needs oxygen-rich blood to function through the right coronary artery and left coronary artery.
The function of the coronary arteries is to supply blood to the heart muscle, since it needs oxygenated blood in order to function properly and eliminate the blood from which the oxygen has already been extracted. The left coronary artery is divided into a series of branches: anterior descending and circumflex and is responsible for transporting blood to the left ventricle of the heart and the left atrium. On the other hand, the right coronary artery is divided into the right posterior descending artery and the marginal artery, and its function is to transport oxygenated blood to the right ventricle, right atrium, towards the sinoatrial node of the right atrium wall and the aurioventricular node.
The right coronary artery arises in the right atrium of the heart and lungs and is then introduced into the right atrioventricular sulcus and traversed to the posterior ventricular sulcus forming the posterior ventricular artery. The right coronary artery can also be located in the right ventricle and in the lower region of the left ventricle. On the other hand, the left coronary artery is located by irrigating the anterior and lateral face of the left ventricle.
The left coronary artery forms the following trunk or branches:
The right coronary artery, born in the aortic sinus, surrounds the heart. Its ramifications are as follows:
Coronary artery disease is the most common type of heart disease and is the leading cause of death among men and women. This condition occurs when the arteries that supply blood to the heart become hard and narrow. This usually occurs as a result of cholesterol building up in the walls of the artery. This buildup is called arteriosclerosis. As the arteries fill with cholesterol, the blood cannot circulate fluidly, and the heart does not receive the necessary flow of oxygen. Symptoms that a person may experience include
The causes of the disease are smoking, high blood pressure, high cholesterol, sedentary lifestyle and diabetes. Age, family history, and sex are risk factors, so it is important to apply appropriate prevention methods to prevent the onset of these diseases. The treatment indicated is based on three different aspects:
