If you have heart disease, you should seek medical attention if your condition gets worse for any reason. Prompt medical attention may catch problems before shock occurs. Taking your medicines as prescribed can also prevent shock. Prevention of coronary artery disease is probably the best way to prevent this condition. Control of coronary risk factors such as high blood pressure, diabetes, smoking, and high cholesterol can also help.
If untreated, this condition usually causes death. If you survive, the long-term effects depend on the cause and the speed of diagnosis and treatment. Permanent organ damage, especially to the kidney and brain, can occur.
There are no risks to others.
