Some people say that nitroglycerin is a "magic bullet" for heart disease patients, but if the heart is uncomfortable, just take one pill of nitroglycerin under the tongue! Ineffective? One more pill is fine?

Is there a scientific basis for this approach? of course not! Nitroglycerin can only relieve one disease, other heart diseases will not save lives but will kill you!

What kind of pain does nitroglycerin relieve?

Nitroglycerin is ineffective or even harmful to chest pain caused by myocardial infarction! Can't distinguish between angina and myocardial infarction? The doctor tells you how to distinguish:

1. Pain: Angina pectoris and myocardial infarction have the same basis. Both plaque ruptures cause heart pain. The location and range of the pain are similar. However, the pain of myocardial infarction is more severe than that of angina, which sometimes makes people feel the same. Kind of near death.

2. Pain time: angina pectoris attack time is 3~5 minutes; acute myocardial infarction chest pain time can be several hours or longer.

3. Inducing factors: exercise or emotional excitement may induce angina pectoris; the inducing cause of myocardial infarction is not obvious.

4. Accompanying symptoms: angina pectoris rarely has accompanying symptoms; acute myocardial infarction is accompanied by vomiting, cold sweats, dizziness, shortness of breath, weakness or collapse.

5. Relief: Symptoms of angina pectoris will be relieved quickly after taking nitroglycerin; but after taking nitroglycerin in myocardial infarction, the symptoms will not be relieved, but may worsen!

For severe chest pain, you can take 1 tablet of nitroglycerin first. If the symptoms are not relieved after 5 minutes, please call the emergency number to the hospital immediately!

When are the different standing first aid medicines taken?

1. Aspirin

The clinical application of aspirin is mainly for prevention and treatment. It is suitable for people who have had cardiovascular and cerebrovascular diseases and who are very likely to develop cardiovascular and cerebrovascular diseases.

The effect is good when used on an empty stomach: Generally, the effect is best when taken on an empty stomach at night. If there is obvious gastrointestinal reaction, it can be taken after breakfast.

It takes a few hours to work, and it is not an emergency: for acute myocardial infarction, aspirin has a slower effect, at least a few hours. If there is no other emergency medicine around, only aspirin, the dosage should be 300 mg, rather than just taking "two tablets." In addition, in order to speed up the absorption effect, chewing and taking is more useful than "drinking and swallowing".

2. Suxiao Jiuxin Pills

Suxiao Jiuxin Pills are mainly used in emergencies, people at high risk of coronary heart disease**.

Take it for chest tightness: When you have chest tightness, precordial discomfort, left shoulder soreness and other aura symptoms, you should quickly take Suxiao Jiuxin Pill, and you must not wait for the typical angina pectoris to take it again.

Generally, it will take effect within a few minutes after taking it, which can effectively prevent sudden death. However, Suxiao Jiuxin Pill is only an emergency medicine and cannot cure the disease fundamentally. See a doctor as soon as possible after the symptoms are relieved.

Sublingual oral administration and quick absorption: Suxiao Jiuxin Pills are suitable for sublingual oral administration. The active ingredients of the drug are absorbed through the sublingual mucosa and can quickly enter the blood circulation. In order to exert the effect more quickly, the pill can be crushed and then placed under the tongue.

If the symptoms are not relieved after two consecutive doses, the patient should be sent to the hospital in time.
