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.

Will there be any sequelae from cardiogenic sudden death?

So, sudden cardiac death is firstly a sudden event. Whether there are sequelae depends greatly on whether timely rescue was administered at the time of the cardiac arrest. If effective cardiopulmonary resuscitation is given within a short time, generally within 4-6 minutes, then the patient's vital signs including consciousness might gradually recover, and it's possible that no severe sequelae will remain. However, if the rescue is not timely, it's possible for the heartbeat and breathing to be restored but not consciousness, leading to brain death and a vegetative state. This is a possibility.

The difference between sudden cardiac death and myocardial infarction.

Sudden cardiac death refers to the sudden death of a patient caused by various heart diseases. The most common causes include malignant arrhythmias such as ventricular fibrillation and ventricular tachycardia, severe bradycardia, significant valvular dysfunction, or the sudden occlusion of the coronary arteries leading to death. Myocardial infarction, on the other hand, refers to the sudden cessation of blood supply to the heart vessels, causing myocardial death and leading to arrhythmias or valvular dysfunction, which presents a range of symptoms in patients. Myocardial infarction can result in death in 30% of patients, but with medical intervention, the mortality rate can significantly decrease. Therefore, in cases of sudden cardiac death, the patients are already deceased. However, the mortality rate from myocardial infarction under natural circumstances is relatively high, reaching 30%. With current medical interventions, the rate of mortality due to sudden cardiac death can be reduced to less than 10%.

Golden hour for emergency treatment of cardiogenic sudden death

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.

Is there a difference between sudden cardiac death and myocardial infarction?

Sudden cardiac death refers to the death of patients caused by various reasons such as cardiac enlargement, ventricular aneurysm, cardiac valve dysfunction, arrhythmias, and cardiac infections. Myocardial infarction leading to myocardial death is just one type of sudden cardiac death, mainly due to insufficient cardiac blood supply, leading to arrhythmias, heart failure, shock, acute death caused by the formation of intracardiac thrombosis, or death caused by complications after a heart attack. Therefore, the range of sudden cardiac death is quite broad, including myocardial infarction.

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.
