Don't underestimate high blood pressure. Coronary heart disease, a complication of high blood pressure, can be serious and even fatal.

Hypertension, as a chronic disease, endangers our health. If blood pressure is allowed to rise, it will bring about a series of cardiovascular diseases, coronary heart disease being one of them.

The full name of coronary heart disease is coronary atherosclerotic heart disease, which refers to heart disease caused by atherosclerosis of the coronary arteries, leading to stenosis or occlusion of the lumen, resulting in myocardial hypoxia or necrosis, also known as ischemic heart disease.

The blood supply of the heart comes from the left and right coronary arteries. The circulation of the heart itself is also called coronary circulation. Simply put, the heart pumps blood to our whole body to provide blood. The blood supply of the heart itself is provided by the coronary arteries, which shows the importance of the coronary arteries. The coronary arteries are divided into left and right branches, which continuously supply blood to the heart. Atherosclerosis refers to the lesions of the affected arteries starting from the intima, with lipid accumulation, fibrous tissue hyperplasia and calcification, and gradual degeneration and calcification of the middle layer of the artery, on this basis, secondary plaque bleeding, plaque rupture and local thrombosis. Hypertension is caused by excessive pressure of blood pressure on the blood vessel wall, which leads to the above series of changes, and thus hypertension is discovered as coronary heart disease.

In 1979, the World Health Organization divided coronary heart disease into latent or asymptomatic coronary heart disease, angina pectoris, myocardial infarction, ischemic cardiomyopathy, and sudden death. Now we divide it into two categories based on the characteristics of the disease and the principles of treatment. One is chronic coronary artery disease, including stable angina pectoris, ischemic cardiomyopathy and latent coronary heart disease. One is acute coronary syndrome, including unstable angina pectoris, non-ST-segment elevation myocardial infarction and ST-segment elevation myocardial infarction. These are all because the coronary artery cannot provide the amount of blood required by the myocardium, and it cannot meet the needs of myocardial metabolism. You can't just let the horse run without giving it grass to eat, so the myocardium will have ischemia and hypoxia. Temporary ischemia and hypoxia will cause angina pectoris. If the myocardial ischemia persists for a long time, it will lead to myocardial necrosis, which is the myocardial infarction we often hear.

The most common type of chronic myocardial ischemic syndrome is stable angina pectoris, also known as exertional angina pectoris. It is called this because angina pectoris often occurs after labor and lasts for a few minutes. Rest or taking nitroglycerin can relieve the pain. This state can remain unchanged for several months.

What does angina pectoris feel like?

The specific description is the squeezing pain or stuffiness in the front chest, mainly behind the sternum, which can radiate to the precordial area and the ulnar side of the left upper limb. In fact, with the increasing pressure and workload of modern people, young people often feel angina pectoris. Once any chest discomfort occurs, you must be vigilant and don't have the fluke mentality of being young and healthy. The symptoms of angina pectoris appear. This is the myocardium sending us a signal to remind us that we should pay attention to our bodies. At this time, we need to actively adjust our lifestyle. First of all, we must avoid various causes of angina pectoris. Secondly, we must eat a light diet. Don't continue to challenge foods that are too oily or too spicy. Don't eat too much at one time. Quit smoking, quit smoking, quit smoking, quit smoking, and say it three times. Limit the amount of alcohol. Reduce the psychological burden and ensure appropriate physical exercise. If it still cannot be relieved, you need to rely on drug treatment. The specific drugs also need to be formulated with professional doctors according to the condition to develop the most suitable plan.

Let's talk about acute coronary syndrome. The most common one is unstable angina. The symptoms are similar to stable angina, but the difference is that the degree of angina is more severe and lasts longer. Angina will occur even in the rest stage, and the attacks are frequent at night. The attack is accompanied by sweating, nausea, vomiting, palpitations or difficulty breathing. Sublingual nitroglycerin cannot relieve the symptoms. At this time, you need to go to the hospital for treatment immediately. The doctor may give a small dose of sedatives, and then give the medicine as needed by assessing the level of danger. After treatment, the patient's symptoms will be relieved, but you must not take it lightly at this time. After discharge, you still need to take medication, adjust your work and rest schedule, control blood lipids, and control blood pressure.
