If cardiogenic sudden death is promptly rescued, it is possible to save the individual. For example, if we immediately perform on-the-spot rescue after cardiogenic sudden death occurs, administering CPR within 4-6 minutes, then a large number of people can be rescued successfully. Some diseases might not even leave any sequelae. The key lies in the timing of the rescue. We say that time is life. For patients who suffer from cardiogenic sudden death, we must act immediately on the spot, wherever the sudden death occurs, to start the rescue, immediately initiating artificial respiration and external chest compressions.

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.

Can sudden cardiac death be hereditary?

Sudden cardiac death has genetic characteristics, and common causes of sudden cardiac death mainly include the following aspects: Coronary heart disease, angina, and myocardial infarction, especially acute myocardial infarction, often lead to sudden death in patients; Secondly, long QT syndrome and Brugada syndrome are also common diseases causing sudden cardiac death and have genetic characteristics as hereditary arrhythmogenic disorders; Thirdly, aortic dissection or pulmonary embolism. These diseases are usually not highly related to genetics but can also cause sudden cardiac death, hence sudden cardiac death is genetic.

The difference between sudden cardiac death and myocardial infarction.

Sudden cardiac death and myocardial infarction are both types of coronary heart disease; they are classified under coronary heart disease. Sudden cardiac death is mostly caused by extensive myocardial infarction, with some patients experiencing it due to severe arrhythmias leading to sudden death. The primary clinical symptoms of myocardial infarction are typically those of coronary heart disease, including chest tightness, chest pain, and sweating. Sudden cardiac death can be triggered by myocardial infarction, but the two are not the same. Having a myocardial infarction does not necessarily result in sudden death, and myocardial infarction can be alleviated with treatment.

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.

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%.
