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.

Precursors of cardiogenic sudden death during sleep

Before the onset of cardiac arrest during sleep, patients often exhibit symptoms of coronary heart disease such as chest tightness, shortness of breath, and palpitations. Often, these individuals do not pay enough attention to the symptoms, do not undergo timely medical examinations at a hospital, and consequently, there is a delay in the treatment of the condition. It is very unfortunate that sudden deaths occur during sleep, possibly due to fatigue, poor rest, and underlying heart disease, which then leads to cardiac arrest. The precursors of such events can vary from person to person; symptoms may include chest tightness and palpitations, among others. Therefore, it is important that we pay attention to these signs.

Cardiogenic sudden death is often caused by what reasons and how to avoid it?

The most common cause of sudden cardiac death is currently acute myocardial infarction caused by coronary heart disease. The following measures can often effectively prevent sudden cardiac death: First, maintain good lifestyle habits, such as a low-salt, low-fat diet, maintain good emotional health, avoid extreme emotions, quit smoking, limit alcohol consumption, and regular exercise is important. Second, active pharmaceutical treatment, such as in cases of hypertension, hyperlipidemia, or diabetes, should be under the guidance of a doctor. It is crucial to use prescribed medications to lower blood pressure or blood sugar levels and control high blood pressure, high cholesterol, or high blood sugar. Actively managing these conditions can effectively prevent the occurrence of coronary heart disease.

Does sudden cardiac death relate to coronary heart disease?

Some studies suggest that 70% of sudden cardiac deaths are caused by arrhythmias. Most of these arrhythmia-induced sudden deaths are associated with coronary artery atherosclerosis. Some are caused by acute myocardial infarction leading to sudden cardiac death. These are all caused by coronary heart disease. Therefore, sudden cardiac death is related to coronary heart disease. Thus, if coronary heart disease is suspected in a patient, it is crucial to perform early examinations and treatments to prevent the occurrence of myocardial infarction. Typical symptoms of coronary heart disease include intermittent chest tightness and chest pain, which can improve after a few minutes, and should therefore be taken seriously.

Is sudden cardiac death related to eating a large number of eggs?

Sudden cardiac death is mostly due to coronary artery atherosclerotic heart disease, where the patient suffers from a large myocardial infarction. This is directly related to atherosclerosis, rupture of atherosclerotic plaques, formation of thrombosis, and obstruction of the coronary arteries. Therefore, the foundation of this disease is primarily hyperlipidemia and arteriosclerosis. Eating a lot of eggs is certainly not beneficial for arteriosclerosis and hyperlipidemia. We believe that there is definitely a connection, but it is not the only factor. For example, high blood pressure, diabetes, smoking, drinking, and other poor lifestyle habits are all related to heart disease. Thus, eating eggs is just one of the risk factors.

Is cardiopulmonary resuscitation effective for sudden cardiac death?

Is cardiopulmonary resuscitation useful for sudden cardiac arrest? Of course, it is useful. The emergency measure for sudden cardiac arrest is to perform cardiopulmonary resuscitation. If the patient receives CPR within four minutes, they are very likely to survive. If there is a delay beyond four minutes, the patient’s life might still be prolonged if resuscitated, but they might suffer brain death and potentially become vegetative. Therefore, it is crucial to administer immediate cardiopulmonary resuscitation to a patient experiencing sudden cardiac arrest, as this is the primary method of resuscitation.
