Hi, Thanks for writing in. I understand your predicament. Sudden cardiac arrest is a condition which is significantly more common in people with heart disease. Additionally, diabetes is a major risk factor for diabetes. However, it is also known to occur with no known risk factors. Many a times, it can be due to ventricular fibrillation, a condition in which the ventricles ( the chambers of the heart which pump the blood to the whole body) beat very fast and irregularly. VF can sometimes be triggered by a heart attack or an electrolyte disturbance. Electrolyte disturbances would be quite common if you had been hospitalized for an infection. If the SCA in your case was due to VF, it can be prevented by putting a implantable cardiac defibrillator. I would also suggest that a treadmill test or a nuclear stress test be done for you to totally rule out heart disease. Further, its extremely important to keep your diabetes under control. Also, you should regularly examine your feet and get the smallest of injuries treated by a physician. SCAs unfortunately cannot be predicted and it is better to take preventive steps in this case. Hope this helps.
