Overview
Coronary arteries, which are responsible for sending blood to muscles (myocardium) that move the heart, become narrow or stiff, and are a general term for diseases caused by the inability to send enough blood to the heart muscle.Cholesterol clumps accumulate on the walls of blood vessels, making it difficult for blood to pass through, and hardening of blood vessels due to aging (arterial sclerosis).One of the most common diseases is angina, which causes chest pain and difficulty breathing due to poor blood flow, and myocardial infarction, which causes blood clots in the coronary arteries to stop flowing completely and causes pain and pressure in the chest.cause
The main cause of ischemic heart disease is arteriosclerosis.Among them, myocardial infarction occurs when fat such as cholesterol is deposited in the inner membrane of blood vessels as they age, blood vessels (coronary arteries) become narrower, cells in the inner membrane are broken, blood clots form, and blood vessels become clogged.If the blood vessel is completely blocked and the blood flow disappears, the myocardial cells are necrosis and myocardial infarction occurs.In addition to aging, arteriosclerosis accelerates due to high blood pressure, hyperlipidemia, smoking, obesity, and diabetes, and the risk of heart disease increases, which is said to be one of the five major risks of hardening.Arteriosclerosis is also affected by angina, which occurs when blood vessels become narrow and blood flow deteriorates suddenly and when intense exercise or stress is applied.Cold stimulation and smoking can cause blood vessels to cramp and cause angina.symptom
The symptoms vary depending on the disease, but the common symptoms include strong pain, pressure, difficulty breathing, cold sweat, and consciousness disorder.Pain is often felt in deep parts of the body, and often lasts at most 15 minutes for angina and 20 minutes for myocardial infarction.The initial symptoms of angina include ′a chest pain lasts for a few minutes when you run up stairs or slopes,′ and ′a chest pain or a pain wakes you up when you go to the bathroom or wash up in the early morning.′In the case of myocardial infarction, it is characterized by sudden chest pain for more than 15 minutes regardless of exercise or rest, and symptoms such as palpitations, shortness of breath, and dizziness along with chest pain.examination and diagnosis
When diagnosing ischemic heart disease, it was first confirmed that there were symptoms of angina and myocardial infarction.An electrocardiogram is performed to check whether or not ischemia is present.In the case of angina, an electrocardiogram when symptoms appear is required, so a device (motor load electrocardiogram) for recording an electrocardiogram during exercise is used.In order to check the contraction force and blood flow of the heart muscle, ultrasound (echocardiogram) examination and myocardial scintigraphy (an examination to see if blood flow reaches each part of the heart by injecting a small amount of radiation material) were performed.MRI examinations can also monitor the movement and condition of the heart muscle.A CT examination of the coronary artery allows you to observe the stenosis of the coronary artery directly, and blood tests are conducted to check the presence or absence of the components of the necrotized myocardium.treatment
There are three main treatments: drug therapy, coronary angioplasty (catheter-based surgery), and coronary bypass surgery.Drugs that expand blood vessels, suppress arteriosclerosis, and prevent blood clumping are used.In the case of angina pectoris, such medication is the basis.Coronary angioplasty is an intravascular operation in which narrowed or clogged coronary arteries are spread by catheterization.In principle, local anesthesia requires a short operation time and relatively little physical burden on patients.If this treatment is difficult, coronary artery bypass surgery is performed to connect blood vessels called bypass.In the case of myocardial infarction, the risk of heart failure increases over time, so treatment is needed as soon as possible.In addition, rehabilitation and dietary guidance will be provided to improve the movement of heart muscles.precautions after prevention/treatment
Arteriosclerosis, which causes ischemic heart disease, is often caused by lifestyle-related diseases such as hyperlipidemia, high blood pressure, and diabetes, so improving diet and developing exercise habits can help prevent it.Following the doctor′s instructions after the onset of the disease, it is important for the recurrence and prognosis of life after treatment to have regular lifestyle habits at the same time as drug therapy.Specifically, it is necessary to exercise moderately, improve bowel movement to avoid blood pressure rise due to defecation, and quit smoking.
