Heart Attack: What is it?

A heart attack occurs when blood flow to the heart stops or stops. If the heart does not receive enough oxygen-rich blood, the affected area can be damaged. As a result, the muscles inside the heart begin to die. Heart failure and other serious complications can occur when your heart does not receive the blood and oxygen it needs to function properly.

A heart attack is a medical emergency that can kill you. You are more likely to have a successful outcome if you receive treatment to restore normal blood flow to your heart as soon as possible.

Symptoms

Heart attack symptoms can vary. Symptoms may be mild for some people. Some suffer from severe symptoms. Some people don’t show any symptoms beforehand.

Heart attack symptoms include:

  • Chest pain or discomfort that may feel like pressure, tightness, pain, squeezing, or pain
  • Pain or discomfort that spreads to the shoulders, arms, back, neck, jaw, teeth, or sometimes the upper abdomen;
  • Cold dessert
  • Fatigue
  • Heartburn or indigestion
  • Mild headache or sudden dizziness
  • Nausea, shortness of breath
  • A heart attack can start with sudden cardiac arrest.

A sudden heart attack may occur. However, many people experience early warning signs and symptoms. Angina, or persistent chest pain or pressure that persists after rest, can be an early warning sign. A brief decrease in blood flow to the heart causes angina.

 

Causes of heart attack

Blood that is rich in oxygen must flow continuously to your heart muscle. This vital supply of blood is provided to your heart by your coronary arteries. When you have coronary artery disease, these arteries become narrow, restricting blood flow. A coronary episode happens when the blood supply is intruded.

Plaques are the result of fat, calcium, protein, and inflammatory cells building up in your arteries. On the outside, these flatbreads are hard, but on the inside, they are soft and spicy.

As the blade hardens, the outer shell breaks off. This is known as a crack. Platelets (the round molded things in your blood that help thicken it) come to the area and form a blood clot around the plaque. Your heart muscle is starved of oxygen when a blood clot blocks your artery. Muscle cells die quickly, causing damage that lasts forever.

Heart attacks can sometimes result from coronary artery spasms. During this coronary spasm, your arteries narrow or spasm, disrupting the blood supply to your heart muscle (ischemia). Even if you do not have severe coronary artery disease, it can still occur at rest.

Blood travels through each coronary artery to a distinct area of your heart muscle. The size of the blocked artery’s supply area and the time between attack and treatment determine the extent of muscle damage.

After a heart attack, your heart muscle begins to heal. It takes about eight weeks. A scar similar to a skin lesion develops in the affected area. However, the newly formed scar tissue does not move as it should. As a result, after a heart attack, your heart can’t pump as hard. The size and location of the scar determine how much this ability to pump is affected.

Resistance

It is never too late to take preventative measures, even if you have already experienced a heart attack. Here are ways to prevent coronary episodes

  • Maintain a healthy lifestyle.
  • Avoid smoking.
  • Follow a heart-healthy diet to keep your weight under control.
  • Manage stress and exercise regularly.

Oversee other medical matters. Diabetes and high blood pressure are two conditions that make a person more likely to have a heart attack. Find out how often you need checkups from your doctor.

Take your medication as directed. Your doctor may give you medicine to keep your heart healthy and work better.

To help someone with a heart attack, it’s also a good idea to learn proper CPR. Consider enrolling in a first aid certification program that will teach you CPR and how to use an automated external defibrillator (AED).
