Sun Yuan, a 73-year-old Qingyuan native, is an empty nester, his wife left early, and the children are not around, so his life is hard. Although this is the case, it did not delay Sun Yuan to enjoy his old age in peace, and there were not too many worries and worries.
However, the sky is unpredictable. When people get older, they have to admit that some diseases do appear quietly and become a direct cause of endangering life and health, if it is just some common geriatric diseases, but it is a serious heart disease.
That night, Uncle Sun was happily dancing with his aunt in the square, and it was when he was happy, but he suddenly felt an indescribable dizziness, accompanied by a tingling pain in his heart. Had to let him go home early to rest.
When I got home, I sat on the sofa for a while before I reacted, and the discomfort in my body disappeared. When you think about it, this is not the first time this has happened. Should I pick a time to go to the hospital?
But then I thought about it, where do people in their seventies say that they are not sick, what they are experiencing, maybe many people are also experiencing the same, why bother making such a fuss, don't scare yourself. Thinking about it like this, I felt a lot more comfortable, so I simply stopped paying attention to it, what should I do.
But in the face of disease, people's own strength is actually very small, if we don't pay attention to the signals sent by the body, wait until the day of being counterattacked, everything will become very serious. Sure enough, this was fulfilled in Uncle Sun's body.
That afternoon, Uncle Sun woke up from a nap and felt something was wrong in his sleep, and there was always a sense of oppression sweeping in, making it impossible for people to breathe normally. I really couldn't sleep and got up, but I didn't expect it to be the same after I got up.
At that time, Uncle Sun was a little flustered, covering his chest with one hand and supporting the sofa with the other, thinking about whether he could relieve it a little, but after such an operation, it still had no effect. Things have come to this point, and Rao is a person who understands and knows that it is time to go to the hospital.
Sun Yuan also had this idea, and went to the hospital with all his strength. After the doctor's examination, Uncle Sun couldn't help but be a little afraid of the final result.
"Uncle, why are you in the hospital? If you look at this piece, there are three coronary arteries in the human heart, and you have two clogged arteries. The doctor said with a serious face, and then told him what the three coronary arteries were all about.
The heart is one of the most important organs in the human body, and its main function is to pump blood throughout the body to maintain the proper functioning of the ecosystem. The heart itself relies on the coronary arteries, a network of blood vessels that run through the surface of the heart and are responsible for transporting oxygenated blood directly to the heart muscle tissue.
Generally speaking, we are talking about the three main coronary arteries in the heart, they are the left main coronary artery, the left anterior descending coronary artery, and the right coronary artery.
The left main coronary artery is short and thick, it originates from the root of the aorta and soon after divides into two main branches: the left anterior descending and the left spin. The left anterior descending artery runs down the anterior cardiac septum and supplies blood to the anterior wall of the heart and part of the ventricular septum; The left branch runs posteriorly around the left side of the heart and supplies the lateral and dorsal walls of the left ventricle. The branch network of these two arteries extends throughout the left ventricle, providing it with an abundant blood supply.
The right coronary artery originates from the aorta and travels down the right edge of the heart to supply the right ventricle, part of the dorsal wall of the left ventricle, and the atria. In about 60-70% of the population, the right coronary artery also extends posteriorly, forming the posterior descending artery that supplies blood to the posterior part of the ventricular septum.
The health of the coronary arteries is directly related to heart function and overall health. Coronary artery diseases, including coronary atherosclerosis, thrombosis, etc., can seriously affect the blood supply to the heart muscle and may cause serious diseases such as angina pectoris and myocardial infarction.
After hearing this, Sun Yuan finally began to pay attention to it, and after thinking for a while, he asked, "Then what will be the impact of this situation of blocking one or two?" ”
The coronary arteries are vital blood vessels that supply blood to the heart muscle and ensure its proper functioning. The human heart has roughly three main coronary arteries, which are located in different parts of the heart and are responsible for carrying oxygen-filled blood to the heart.
When one or both coronary arteries become blocked, the flow of blood to the heart muscle is blocked, and a part of the heart is damaged or malfunctions due to ischemia. This condition can lead to a variety of health problems, the main effects of which can be summarized in three areas: clinical symptoms caused by insufficient blood supply, cardiac dysfunction, and arrhythmias.
First, chest pain is most commonly seen as a clinical symptom of inadequate blood supply, especially during physical activity or emotional agitation. This is because the heart muscle is unable to get enough oxygen due to blockage of the coronary arteries in the face of increased oxygen demand, resulting in myocardial ischemia. Patients may describe the pain as feeling like a weight pressing on the chest, or a tight, pressing sensation in the chest. In addition to chest pain, patients may also experience symptoms such as difficulty breathing, fatigue, dizziness, etc.
Second, a persistent lack of blood supply to the heart can lead to heart dysfunction. Prolonged hypoxia of the myocardium not only affects the heart's ability to pump blood, but may also lead to the death of myocardial cells, which in turn can lead to myocardial infarction. If the blockage of the coronary arteries is located in a critical part of the heart, even if only one or two coronary arteries are blocked, it may cause extensive myocardial damage, reduce the heart's ability to pump blood, and cause heart failure.
Heart failure is a serious condition in which the heart is unable to pump blood efficiently to meet the body's needs, resulting in extreme breathing difficulties, decreased activity tolerance, and fluid accumulation in different parts of the body.
Finally, arrhythmias are also an important effect of coronary artery blockage. The electrophysiological activity of the heart depends on a good blood supply. When myocardial ischemia or infarction occurs, the electrophysiologic properties of cardiomyocytes may be altered, leading to arrhythmias.
There are many types of arrhythmias, ranging from more benign premature beats to potentially fatal ventricular tachycardia or ventricular fibrillation, which can be a consequence of coronary artery blockage. Severe arrhythmias can not only cause symptoms such as palpitations, syncope, but can also lead to sudden death.
In summary, a blockage of even one or two coronary arteries can have a profound impact on an individual's health. This includes clinical symptoms such as chest pain due to insufficient blood supply, cardiac dysfunction, and arrhythmias.
Therefore, the maintenance of cardiovascular health, timely diagnosis and effective treatment of coronary artery disease are particularly important. Understanding these effects helps us recognise the severity of coronary artery disease so that preventive measures such as maintaining healthy lifestyle habits and early treatment can avoid adverse health consequences.
