What is the difference between heart attack and cardiac arrest, know which is more dangerous?:A heart attack, medically known as a myocardial infarction, occurs when there is a blockage in the arteries that supply blood to the heart. This blockage is usually caused by cholesterol and fat deposits.

News Topical, Digital Desk : The heart is our body's most vital organ, constantly pumping blood to deliver oxygen and essential nutrients to every part of the body. This same process also helps remove waste products like carbon dioxide from the body. When the heart malfunctions, it affects the entire body. People often mistake heart attack and cardiac arrest for the same thing. However, according to medical science, these are two distinct conditions. Both can be fatal, but their causes, symptoms, and effects are different. So, let's explain the difference between cardiac arrest and heart attack, and which one is more dangerous.

What is a heart attack?

A heart attack, medically known as myocardial infarction, occurs when the arteries supplying blood to the heart become blocked. This blockage is usually caused by cholesterol and fat deposits. When blood is unable to reach the heart muscle, it gradually damages that area. This damage can be serious if not treated promptly.

Common symptoms of a heart attack

Common symptoms of a heart attack include chest pressure or tightness, shortness of breath, unusual fatigue, cold sweats, dizziness, nausea or vomiting, and pain in the jaw, neck, arms, or back. In many cases, heart attack symptoms can be mild or develop gradually, so ignoring them can be dangerous.

What is cardiac arrest?

Cardiac arrest is a serious condition that occurs suddenly when the heart stops beating. This is caused by a malfunction in the heart's electrical system. When the heart stops beating properly, blood supply to vital organs such as the brain and lungs is cut off. This can cause immediate unconsciousness and respiratory arrest. If treatment is not received within minutes, this condition can be fatal.

Key differences between heart attack and cardiac arrest

A heart attack is a problem related to blood circulation, in which blood is unable to reach the heart. Cardiac arrest is a problem with the heart's electrical system, in which the heart stops beating altogether. Experts say both conditions are medical emergencies, but cardiac arrest is considered more dangerous because the person becomes unconscious within minutes and the heart can stop completely. While a heart attack may offer some time for treatment after symptoms appear, delay can be fatal.
