According to cardiologist in Mumbai, the medical terms 'heart attack' and 'cardiac arrest' are frequently used interchangeably, but they are actually not similar. Although it's true that having a heart attack may eventually lead to cardiac arrest, most of the times these incidents happen independently of each other.
One way to understand the difference between heart attack & cardiac arrest is that one is a plumbing issue, while the other is an electrical issue.
What happens in a Heart Attack?
A linkage of blood vessels known as coronary arteries encloses the heart and delivers it with oxygen-rich blood. The heart requires this oxygen to function well. A heart attack occurs when a coronary artery gets blocked, which ends the flow of blood to the heart, says one of the top cardiac surgeons in Mumbai, Dr. Bhasker Semitha. All or section of the heart muscle turns out to be cut off from its oxygen supply.
Less often, a heart attack also can occur by a coronary artery spasm, Dr. Bhasker says. During coronary artery spasm, the arteries tighten on and off,which leads to a shortage of blood supply to the heart. A coronary spasm might occur at rest and could even come about in people without major coronary artery disease, Dr. Bhasker further added. If spasm of coronary artery occurs for a long duration, a heart attack can take place.
As per information given by various cardiac surgeons in Mumbai, a heart attack damages your heart since it leads to compromise in blood flow restricting from a clogged or spasming blood vessel.
Major Signs & Symptoms of Heart Attack:
Here are the top common symptoms of a heart attack, as per best heart surgeon in Mumbai, Dr Semitha:
- Discomfort (pain or pressure) in the chest or stomach
- Feeling of chest tightness
- Pain that radiates to the jaw or arm
- Trouble in Breathing
- Loss of consciousness
- Heart palpitations
- Pressure in the upper back
Upto 1/3 of heart attack patients don't experience chest pain or discomfort with heart attacks, says some of the best cardiac surgeons in Mumbai. In particular, women are more probable to have uncommon symptoms.
Symptoms that women experience might include:
- Gastric pain
- Pain that exudes to the arm
- Shortness of breath
- Dizziness or Loss of consciousness
It's important to understand that just like no two people are the similar, no two heart attacks are the identical. Even for someone who has before now had a heart attack, indications of another attack might sometimes be quite different.
What happens in a Cardiac Arrest?
When you undergo cardiac arrest, your heart stops working well since there is a malfunction in the electrical system. The heart then beats perilously fast. The heart's two big chambers may fluster or have a tremor, and blood is not supplied all through the body. This gives a way to a quick drop in blood pressure and failure of the circulatory system, says some of the heart specialists in Mumbai.
In the initial few minutes of cardiac arrest, the highest concern is that blood flow to the brain is decreased so considerably that an individual will lose consciousness. Death follows unless emergency treatment is begun immediately.
When a heart attack harms or declines an important amount of heart muscle, this sometimes leads to electrical turbulences that put the heart at further risk for cardiac arrest.
Major signs and symptoms of cardiac arrest:
- Loss of consciousness
- Abnormal or Absent breathing
- Chest pain
- Blue discoloration of face
Some individuals experiencing cardiac arrest might feel their heart racing or they might feel giddy. However, more than half of those who go through cardiac arrest experience no prior symptoms.
What is the link?
These two different heart conditions are linked. Sudden cardiac arrest can take place post heart attack, or in the course of recovery. Heart attacks increase the risk for sudden cardiac arrest. Most heart attacks don't lead to sudden cardiac arrest.
But as soon as sudden cardiac arrest happens, heart attack is a common reason. Other heart conditions might also disturb the heart's beat and lead to unexpected cardiac arrest. These comprise of a stiffened heart muscle (cardiomyopathy), heart failure, arrhythmias, mainly ventricular fibrillation, and prolonged Q-T syndrome.
