What is Sudden Cardiac Arrest?
Sudden cardiac arrest happens when the heart stops beating without warning. This is a serious medical emergency. The causes of sudden cardiac arrest can vary, but the result is always the same. Blood flow to the brain and body stops. Without quick help, sudden cardiac arrest can lead to death within minutes. Unlike a heart attack, which is caused by blocked blood flow, sudden cardiac arrest is usually due to a problem with the heart’s electrical system. According to the CDC, this condition affects hundreds of thousands of people each year.
Key Causes of Sudden Cardiac Arrest
Many different issues can cause sudden cardiac arrest. Some are related to heart disease, while others are not. Below are the main causes:Coronary Artery Disease: This is the most common cause. Blocked arteries can reduce blood flow to the heart, leading to dangerous rhythms.Arrhythmias: These are abnormal heart rhythms. Ventricular fibrillation is a type that often leads to sudden cardiac arrest.Structural Heart Defects: Some people are born with heart problems. These defects can disrupt normal heartbeats.Heart Attack: A heart attack can damage the heart muscle. This damage may trigger sudden cardiac arrest.Cardiomyopathy: This means the heart muscle is weak or thickened. It can make the heart more likely to stop suddenly.Inherited Heart Conditions: Some people inherit genes that affect the heart’s rhythm or structure.Drug Use: Illegal drugs or certain medicines can cause dangerous heart rhythms.Severe Imbalance of Minerals: Low or high levels of potassium or magnesium can affect the heart’s rhythm.Other Causes: For example, trauma, severe bleeding, or electrical shock can also trigger sudden cardiac arrest.
Risk Factors to Watch For
Some people have a higher risk of sudden cardiac arrest. For instance, having heart disease or a family history of heart problems increases your risk. Other risk factors include:Previous heart attack or heart failureHigh blood pressureHigh cholesterolDiabetesObesitySmokingHeavy alcohol useOlder ageMale gender
However, sudden cardiac arrest can happen to anyone, even without known risk factors. That is why it is important to know the warning signs and causes.
