Understanding Heart Attacks: The Blockage Crisis

Heart attacks are a serious medical emergency that affects millions in the U.S. each year. A myocardial infarction happens when blood can’t reach a part of the heart muscle. This can cause permanent damage to the heart².

Knowing about coronary artery disease is key to spotting heart attack warning signs. Knowledge can be a lifesaving tool for heart health.

What is a Heart Attack?

A heart attack occurs when coronary arteries block, stopping oxygen-rich blood from reaching heart muscle cells. This can lead to serious heart damage. The sooner treatment starts, the better³.

Symptoms and Warning Signs

Chest pain or discomfort
Shortness of breath
Unusual fatigue
Pain radiating to arm or jaw

About two-thirds of people have warning signs before a heart attack. These can happen days or weeks beforehand. Women may have different symptoms than men².

Causes and Risk Factors

Coronary artery disease is the main cause of heart attacks. Several factors can increase the risk of heart problems:

High blood pressure
Elevated cholesterol levels
Smoking
Obesity
Sedentary lifestyle

Genetics and chronic conditions can also raise the risk of heart issues⁴.

Cardiac Arrest: When the Heart Stops Beating

Cardiac arrest is a serious medical emergency where the heart suddenly stops working. This condition happens when the heart’s electrical system fails. It leads to a sudden stop in blood flow causing sudden cardiac death.

Understanding the Mechanism

Sudden cardiac arrest strikes quickly and without warning. It’s often caused by severe arrhythmia. When the heart’s electrical signals get mixed up, it can lead to ventricular fibrillation. This stops normal blood flow⁵.

In the U.S., about 365,000 people have sudden cardiac arrest each year. Sadly, 95% of these cases are fatal⁵.

Recognizing Critical Signs

Sudden collapse
Loss of consciousness
No pulse
Unresponsiveness
Cessation of breathing

Before the event, people might feel dizzy, short of breath, or have chest pains. They might also feel nauseous, usually an hour beforehand⁵.

Common Causes and Risk Factors

Cardiac arrest can come from many conditions. For young people, common causes include:

Cardiomyopathy
Congenital heart disease
Genetic rhythm disorders
Heart inflammation
Substance abuse

Every year, about 2,000 young people under 25 die from sudden cardiac arrest⁶. Sadly, 90% of cardiac arrests outside hospitals are fatal⁶.

Survival and Intervention

Quick action is key. Doing CPR can greatly increase survival chances⁶. With proper CPR, defibrillator use, and fast emergency help, survival rates can be over 40%⁷.
