What is the worst disease for frequent fainting?

In daily life, everyone should be very afraid that someone or themselves will suddenly faint, because fainting is a very serious matter, and severe fainting may lead to death. And once you find someone fainted, be sure not to move his body, otherwise it will lead to more serious consequences. Some people often faint, and there are many causes of frequent fainting. What is the worst disease that causes frequent fainting?

1. You may encounter sudden fainting in daily life. The ways of dealing with fainting vary greatly. Some people recover on their own within a short period of time and do not take it seriously. Fainting is a sudden, short-term loss of consciousness due to temporary ischemia of the brain for various reasons, which is medically known as "syncope". Normal people may faint under special circumstances, but if a person faints frequently, it may be pathological syncope and he must go to the hospital for examination and symptomatic treatment.

2. Although on the surface, the symptoms of fainting are almost the same, with an instant loss of consciousness, weak breathing, and obvious heartbeat fluctuations...but behind fainting, there are different warnings and symptoms. There are roughly eight common causes of syncope: reflex syncope, orthostatic hypotension syncope, cardiac syncope, cerebrovascular syncope, hypoglycemia syncope, syncope caused by hyperventilation, crying syncope, and anemia syncope.

3. Cardiogenic syncope in medicine usually refers to the syncope phenomenon that can occur due to various heart diseases. Fainting due to this cause is mostly induced by the patient's exertion of force, such as excessive exercise, mountain climbing, etc. There are often palpitations, throbbing in the chest or chest pain before loss of consciousness, and the onset is rapid. Arrhythmia can cause cardiac syncope, and patients will experience complete atrioventricular block, especially when there is Adams-Stokes syndrome, sick sinus syndrome, ventricular or supraventricular paroxysmal tachycardia, atrial fibrillation, etc.; generally, drugs such as quinidine and digitalis are used clinically.

4. Coronary heart disease and myocardial infarction can also cause cardiac syncope. Coronary heart disease can cause syncope due to ventricular arrhythmias caused by acute myocardial ischemia. Most of the patients are elderly patients with hypertension or coronary heart disease. Some of them first experience syncope and arrhythmia, and then develop precordial pain; others first experience angina pectoris and then syncope. The syncope caused by myocardial infarction lasts for a long time, and the patient may experience nausea, vomiting, and general weakness after waking up. In addition, there are some patients, such as aortic stenosis, pulmonary hypertension, valvular heart disease with arrhythmia or heart failure, superior and inferior vena cava occlusion and tension pneumothorax, etc.; all of which will cause decreased cardiac output, global cerebral ischemia and syncope.

5. The corresponding cerebrovascular syncope is most commonly caused by atherosclerosis of the cerebral arteries, followed by cervical diseases such as cervical spondylosis compressing the vertebral artery, polyarteritis Takayasu (pulseless disease), subclavian artery steal syndrome, basilar artery migraine, etc. Migraine usually starts with dizziness and then headache. For transient ischemic attacks of the carotid artery or vertebral artery, the main symptoms are focal symptoms in the vascular supply area, occasionally accompanied by syncope. All symptoms disappear within 24 hours. For some patients with Takayasu arteritis, 1/3 to 2/3 experience syncope, and most patients will develop the disease during activities. The absence of pulsation in all major blood vessels is a characteristic of this disease.

6. Some patients with basilar artery migraine, more common in young women, often have a positive family history. Generally, patients will experience dizziness first and then headache. Syncope often occurs before the headache, loss of consciousness occurs gradually, and there is confusion for several hours. Cerebral vasospasm is considered to be the cause of syncope. The above diseases require timely medical treatment and active treatment. Never be careless or ignore them. These negative attitudes are unscientific.
