Heart attacks that strike young women
Learn about SCAD heart attacks that strike young women. Our experts explains why this type of heart attack differs in diagnosis and treatment.
Sudden cardiac arrest (also called sudden cardiac death (SCD), sudden death, ventricular fibrillation and cardiac arrest) is the sudden loss of cardiac function. Unlike a heart attack – which is a circulation problem where one or more of the arteries delivering blood to the heart are blocked – sudden cardiac arrest is caused by an electrical problem in the heart and is characterized by abnormal heartbeats called arrhythmias. The arrhythmia is called ventricular fibrillation and when it occurs your heart does not pump adequately. Without the pumping function of your heart, no blood is being delivered to other parts of your body, including your brain. Sudden cardiac arrest occurs without warning and is characterized by an abrupt collapse with loss of consciousness and no pulse or breathing.
Sudden cardiac arrest can occur at any age. It can affect anyone – from people in their 40s and 50s with heart disease to young people, who may have an inherited arrhythmia disorder.
Response time is critical for sudden cardiac arrest. The sooner a person is resuscitated, the better chance of recovery. Death can occur within eight to 10 minutes. The number of deaths related to sudden cardiac arrest in the United States each year is more than the total death rate for breast cancer, lung cancer and HIV/AIDS combined. Sudden cardiac arrest is one of the leading causes of death in men and women in the United States, totaling more than 325,000 deaths annually.
If you witness someone collapse from possible cardiac arrest, you can administer Hands-Only™CPR. Even when performed by a bystander, this lifesaving technique has been shown to be as effective as “conventional” CPR in emergencies. There are only two steps to remember:
1. Call 911
2. Push hard and fast in the center of the chest
Don’t worry about whether or not you are doing hands-only CPR “right” or not. You cannot make the victim worse. You can only help. Giving hands-only CPR for a short time to someone who is not really in cardiac arrest is rarely harmful.
The most common underlying reason for people to die suddenly from cardiac arrest is heart disease. Irregular heart rhythms (arrhythmia) cause the heart to suddenly stop beating. Cardiac arrest can be due to:
People who have survived a previous heart attack or have a history of congestive heart failure are four to six times more likely to die suddenly from cardiac arrest. Other less common conditions can induce cardiac arrest, including changes in the heart’s normal size and structure, certain types of physical stress, respiratory arrest, drowning, choking and trauma. It also can occur without any known cause.
Risk factors for sudden cardiac arrest include coronary disease and a family medical history of heart problems.
The Ohio State University Wexner Medical Center has an interdisciplinary program designed to quickly determine causes of sudden cardiac arrest and develop appropriate treatment after the event. Our cardiologists work closely with our Emergency Department to reduce treatment time once an individual with sudden cardiac arrest reaches our hospital. If needed, we also have an outstanding surgery program which includes the ability to offer temporary mechanical support (such as ventricular assisted devices, or VADs) for patients who are in shock and cannot be stabilized.
