Sudden Cardiac death risk?

SCD due to ventricular arrhythmias is the mode of death in about half of patients with heart failure and is particularly proportionally prevalent in ICFRE patients with the early stages of the disease. Patients who survive an episode of SCD are considered to be at very high risk and qualified for the placement of an implantable cardioverter defibrillator (ICD)

Sudden Cardiac death risk: 

Patients may express concerns about the risk of sudden cardiac death during exercise. While the risk of sudden death during exercise increases directly with the amount of time spent in exercise, this association is substantially mitigated by the effects of training. Therefore, patients who undertake an exercise program should be encouraged to gradually increase the duration of aerobic exercise as tolerated, aiming for episodes of at least 30 minutes 5 times a week as an ideal. Once a comfortable duration is achieved, the incorporation of training periods with more intense intervals spaced during exercise can provide an increase in fitness

What is sudden Cardiac death? 

Sudden cardiac death is sudden and unexpected, and death occurs a few minutes after the collapse. It is more common in older people with severe heart disease, although it sometimes happens to young and healthy people with no external signs of heart disease

SCD occurs when not enough blood is pumped to the heart because the arteries can be blocked and immediate resuscitation is needed. Heart rate gets to be chaotic and cannot be controlled: this case is called ventricular fibrillation. The ventricles are the chambers that send blood from the heart to the blood vessels and are severely affected during a sudden cardiac arrest. Blood transports basic substances to cells and visceral organs.  If these structures don't get the blood they need, they start to malfunction and eventually close

It is not the same as a heart attack, but a heart attack can actually cause sudden cardiac death, both during the first few hours of the heart attack and many years after the attack. To differentiate the two, one can think of sudden cardiac death as an electrical malfunction and a heart attack as a cause of blocked arteries (malfunction of the tube). To be more precise, sudden cardiac death occurs when millions of "shorts" occur in the heart, causing the heart pump to fail and interrupting the supply of blood, oxygen and nutrients to sustain life. The person is therefore unconscious. Death can occur in minutes if the situation is not remedied

The only chance of survival for a victim of sudden cardiac death is  "reset" one's heart from an electric shock from a machine known as a defibrillator. There are few types of defibrillators, namely manual external defibrillators (MED), automatic external defibrillators (AEDs) and implantable defibrillators (ICD)

When sudden cardiac death occurs, it cannot be stopped. It takes nine out of ten victims and takes them in minutes. They don't come back. They are gone. But it doesn't have to be that way

They can survive It is likely that you know someone who is "dropped dead" and it is very likely that you have been the victim of sudden cardiac arrest, also known as sudden cardiac death. The disease is more deadly than lung cancer, breast cancer and AIDS combined. Almost half a million victims die suddenly every year, about one every minute. This silent killer is usually not terrifying, but it is terrifying because of its unpredictability
