Angina pectoris is simply a blockage of blood vessels in the heart and insufficient blood supply. What are the symptoms of angina pectoris? Can be divided into typical symptoms and atypical symptoms. Typical symptoms can not be ignored, because if we still carry them, it may lead to myocardial infarction or even shock death. Atypical symptoms need more vigilance, and we often ignore these atypical symptoms, which leads to the progress of the disease.
As a serious symptom of ischemic heart disease, angina pectoris is essentially an imbalance of blood oxygen supply. We know that the beating of the heart maintains the whole blood circulation, and the blood circulation itself needs blood to transport oxygen to maintain it. Once the blood supply is reduced, myocardial ischemia may occur. The blood supply to the heart comes from the coronary arteries around the heart. When the coronary artery has atherosclerotic lesions or the oxygen carrying capacity of blood decreases, the blood oxygen supply of myocardium decreases. When human activity increases, such as overwork or relatively strenuous exercise, myocardial oxygen demand increases, which will produce angina symptoms.
Typical symptoms of angina pectoris
When we encounter sad things, we all have heartbroken experiences, which are relatively tolerable. Once angina attacks, this experience is different. People who haven't experienced it don't know this kind of pain. Usually, it is characterized by heavy compressive retrosternal discomfort (patients often describe it as chest tightness discomfort rather than pain), which often radiates to the left shoulder or upper abdomen, which means that typical angina pectoris occurs in and around the heart.
The symptoms of most typical angina patients are mostly induced by fatigue, which can be relieved by resting or taking nitroglycerin under the tongue.
Atypical symptoms or strange manifestations of angina pectoris
A few angina pectoris showed different parts, even non-painful symptoms. For example, some people suddenly become deaf and their ears are buzzing. Some people wrap their chests with adhesive tape, which is painless, but has a sense of bondage.
Some people have pain around the navel, and they often think that it is appendicitis or abdominal lesions in emergency, but it is actually caused by angina pectoris;
Some people show pain in the soles of their feet, and it hurts when they walk. Some people mainly show toothache or headache.
When myocardial ischemia occurs frequently, these angina pectoris are usually atypical in the elderly, women and diabetic patients.
Treatment strategy of angina pectoris
When the symptoms of angina pectoris rest or cannot be relieved after taking nitroglycerin, you should call 120 to see a doctor at the first time. Although the symptoms of angina pectoris are ever-changing, for emergency patients, most of them can find clues by checking ECG or myocardial enzymes, and there will be myocardial hypoxia. Further comparative examination can clearly see the blockage of blood vessels and make a diagnosis. Treatment methods are divided into interventional surgery and drug therapy, and treatment strategies are divided into three points:
1. Reduce the oxygen demand of the heart
If you have angina pectoris, you must rest. Lying down is more important than anything else. Of course, you must lie down in a safe environment and not move, so that the oxygen demand of the heart will be reduced at the first time.
The drugs to reduce cardiac oxygen demand include organic nitrates (represented by nitroglycerin), β -adrenergic receptor antagonists (Lore drugs) and calcium channel antagonists (represented by horizon drugs). These anti-angina drugs can reduce the workload and oxygen demand of the heart by reducing the heart rate and myocardial contractility.
2. Increase the oxygen supply to the heart
If the angiographic results of patients with angina pectoris are seriously blocked, they often need to be intervened to dredge blood vessels by mechanical means, that is, to directly dilate blood vessels and restore the oxygen supply capacity of the heart to normal; Drugs to improve myocardial oxygen supply include vasodilators, calcium channel antagonists (represented by antiperspirants), statins and aspirin and other antiplatelet drugs.
3. Improve lifestyle and maintain blood vessels.
It is very important to standardize medication and improve lifestyle under the guidance of doctors in the later rehabilitation treatment of angina pectoris. Smoking, alcoholism, overwork, high-fat and high-sugar diet and obesity are all natural enemies of cardiovascular health. Therefore, we should pay attention to a healthy lifestyle, maintain a normal mind, have a balanced diet, exercise moderately, control our weight, and have regular physical examinations to protect blood vessels and prevent angina pectoris.
