Cardiac arrest is now also a very frequent event. We have seen some reports of it occurring frequently at airports, train stations, and on public transport, involving middle-aged, elderly, or even young individuals. The golden window for emergency aid is 4 to 6 minutes, with shorter times being preferable. We say time is life because after 4 to 6 minutes, if effective circulation isn't restored, brain cells begin to die. Even if later resuscitation restores breathing and heartbeat, the individual may end up in a vegetative state. Therefore, within the shortest time frame of 4 to 6 minutes, external chest compressions, including opening the airway and artificial respiration, must be administered. The optimal window is 4 minutes, but no more than 6 minutes.

How to self-rescue from sudden cardiac death

Sudden cardiac death is now also a very critical illness often occurring in coronary heart disease. We frequently see news reports of sudden deaths at airports and public places. At such times, self-rescue is extremely difficult. Unless you have a history of coronary heart disease and carry medications with you, if you experience symptoms like chest tightness and shortness of breath, you could take these medications to help yourself. Otherwise, sudden cardiac death occurs abruptly, causing the heart to stop beating within a very short period, and the patient cannot self-rescue.

How to Self-Check for Precursors of Cardiogenic Sudden Death

The majority of cases of sudden cardiac death are due to coronary artery atherosclerotic heart disease, causing extensive myocardial infarction, hence these patients often have precursors. Some individuals experience acute coronary syndrome due to inflammatory changes, leading to thrombosis; others, such as young people without any underlying conditions, might also experience this, often due to poor lifestyle habits like high stress and lack of sleep among other triggers. Most patients exhibit warning signs, including chest tightness, chest pain, and palpitations – symptoms of heart disease. When these problems occur, it is crucial to promptly visit a hospital for examination to determine if there are issues with the coronary arteries, and if so, to receive timely treatment and intervention.

Is sudden cardiac death hereditary?

The majority of sudden cardiac deaths are caused by acute and extensive myocardial infarction, with some caused by malignant arrhythmias. Coronary atherosclerotic heart disease has a genetic history. Patients with such a family history, especially those with early-onset heart disease family history—that is, a family history of heart disease before the age of 50—should be given high attention. Heart disease has a genetic predisposition, and since sudden cardiac death is a type of heart disease, it also has a genetic predisposition.

The difference between sudden cardiac death and myocardial infarction

Sudden cardiac death and myocardial infarction are both types of coronary heart disease, but they are different from each other. Firstly, having a myocardial infarction does not necessarily result in sudden death. Myocardial damage involves a large area of necrosis in the heart, and the patient may experience symptoms such as chest tightness, shortness of breath, chest pain, and sweating. The main symptom of sudden cardiac death is the abrupt cessation of vital signs, with breathing and pulse disappearing. This condition can be caused by a large and extensive acute myocardial infarction, but it can also be caused by other reasons such as electrolyte disturbances or malignant arrhythmias, which are different causes.

Does sudden cardiac death have a relationship with hypertension?

Sudden cardiac death and hypertension are related, with the most common cause of sudden cardiac death being acute myocardial infarction, which leads to malignant arrhythmias, such as ventricular fibrillation, resulting in sudden cardiac death. In addition, severe aortic dissection can also cause sudden cardiac death, and hypertension is often an important cause of coronary heart disease, acute myocardial infarction, and aortic dissection. Long-term hypertension can lead to the occurrence of arteriosclerosis, resulting in the formation of arterial plaques or aneurysms, such as those occurring in the coronary arteries, causing coronary heart disease and myocardial infarction, or in the aorta, often leading to the formation of aortic aneurysms. When an aortic aneurysm ruptures, it can cause aortic dissection.
