Acute Myocardial Infarction (Heart attack): Causes, Symptoms, First aid & Diagnosis

What is Acute Myocardial Infarction?

Acute myocardial infarction is the medical name for heart attack. A heart attack is a life-threatening condition that occurs when blood vessels flow to the heart is abruptly cut off, triggering tissue damage. The heart requires its own regular supply of fresh air and nutrients, like any muscle in the body. Two large, branching cardiac arteries deliver oxygenated bloodstream to the heart muscle. If some of these arteries or branches becomes blocked suddenly, a part of the heart is deprived of oxygen, a condition called “cardiac ischemia.”

If cardiac ischemia lasts too long, the starved heart tissue dies. This is a heart attack, otherwise known as a myocardial infarction — literally, “death of heart muscle.”

Heart attacks are a respected killer of both men and women in the US. The good news is that excellent treatments are around for heart attacks. These types of treatments can save lives and prevent disabilities.

Cardiovascular system attack treatment works best if it’s given right after symptoms occur. In the event that you think you or someone else has a heart attack (even if you are not fully sure), call The Doctor immediately.

Many heart attack victims are warned of trouble by episodes of angina, which is chest pain that, like a heart attack, is provoked by ischemia. The difference is mainly one of degree: With angina, blood flow is restored, pain recedes within minutes, and the heart is not permanently damaged. With a heart attack, blood flow is critically reduced or fully blocked, pain lasts longer, and heart muscle dies without prompt treatment.

About 25% of all heart attacks occur without any previous warning signs.. They are sometimes associated with a phenomenon known as “silent ischemia” — sporadic disruptions of blood flow to the heart that, for unknown reasons, are painless, although they may destruction the heart tissue. The condition can be recognized by ECG (electrocardiogram) tests. People with diabetes often have silent ischemia.

One fourth of all heart attacks victims die before reaching a hospital; others go through life-threatening issues whilst in the hospital. Serious difficulties include stroke, persistent cardiovascular arrhythmias (irregular heartbeats), heart failure, formation of blood clots in the legs or heart, and aneurysm, or bulging, in a weakened heart step. But those who make it through the first heart attack and are free from major problems a few several hours later stand an improved chance of full recovery.

Symptoms of Acute myocardial infarction (Heart Attack)

While the classic symptoms of a heart attack are chest pain and shortness of breath, the symptoms can be quite varied. The most common symptoms of a heart attack include:

  • Pressure or chest firmness
  • Pain in the upper body, back, jaw, and other locations of the high body that lasts more than a few minutes or which goes away and comes back
  • A suffocating feeling
  • Sweating
  • Nausea
  • Vomiting
  • Panic
  • A cough
  • Dizziness
  • A quick heart rate

It’s important to note that not every people who have cardiovascular attacks go through the same symptoms or the same severances of symptoms. Heart problems is the most commonly reported symptom among both women and men. Nevertheless, women are more likely than men to acquire:

  • Lack of breath
  • Jaw pain
  • Spine pain
  • Lightheadedness
  • Vomiting
  • Nausea


Just how Is Acute Myocardial Infarction Diagnosed?

To determine whether you’ve had a heart attack, your doctor will pay attention to your heart to check on for irregularities in your heartbeat. They may evaluate your blood pressure as well. A medical expert will also run a few different tests if they realise that you’ve had a heart attack. An electrocardiogram (EKG) may be achieved to measure your heart’s electrical activity. Blood vessels tests can even be used to check for proteins that are associated with center damage, such as troponin.

Other diagnostic tests include:

  • A stress test to see how your cardiovascular responds to certain situations, such as exercise
  • An angiogram with coronary catheterization to look for areas of blockage in your arteries
  • An echocardiogram to help identify areas of your heart that not necessarily working properly

Who may be at Risk for Acute Myocardial Infarction (Heart attack)?

Certain factors may increase your risk of having a myocardial infarction.

High Blood Pressure

You’re at greater risk for heart attack if you have high blood vessels pressure. Normal stress is below 120/80 mm Hg (millimeters of mercury) depending on your age. Since the numbers increase, so does your risk of developing heart issues. Having high blood pressure damages your arteries and accelerates the buildup of plaque.

High Cholesterol Levels

Having high numbers of cholesterol in your blood vessels puts you at risk for acute myocardial infarction. You may well be able to lower your cholesterol by looking into making changes to your diet or through certain medications called statins.

High Triglyceride Amounts

High triglyceride levels also increase your risk for having a heart strike. Triglycerides are a type of fat that block up your arteries. Triglycerides from the food you eat traverse your blood vessels until they’re stored in your body, typically in your fat cells. Even so, some triglycerides may stay in your arteries and contribute to the buildup of plaque.

Diabetes and High Blood Sugar Amounts

Diabetes is a condition that causes blood glucose, or glucose, levels to rise. High blood glucose levels can damage bloodstream vessels and ultimately lead to coronary artery disease. This is certainly a serious health condition that can trigger center attacks in a few people.


Your chances of having a heart attack are higher for anyone who is very overweight. Weight problems is associated with various conditions that raise the risk of heart attack.

Smoking cigarettes

Cigarette smoking tobacco products increases your risk for heart assault. It can possibly lead to other cardiovascular conditions and diseases.

Old ages

The risk of having a heart harm increases with age. Guys are in a higher risk of a heart attack after age 45, and women are in a higher risk of a center attack after age 55.

What to do if you or someone else may be having a heart attack

  • Call your local medical emergency number Don’t ignore or attempt to tough out the symptoms of a heart attack for more than five minutes. If you don’t have access to emergency medical services, have a neighbor or a friend drive you to the nearest hospital. Drive yourself only as a last resort, and realize that it places you and others at risk when you drive under these circumstances.
  • Chew up and swallow an aspirin, unless you are hypersensitive to aspirin or have been told by your doctor never to take aspirin. But seek unexpected emergency help first, such as calling your local emergency number.
  • Take nitroglycerin, if prescribed. If you think you’re having a heart attack and your doctor has previously approved nitroglycerin for you, take it as directed. Do not take anyone else’s nitroglycerin, because that could put you in more threat.
  • Begin CPR if the individual is unconscious. If you’re with a person who might behaving a heart attack and he or she is unconscious, tell the emmergency 911 dispatcher or another urgent medical specialist. You may be advised to commence cardiopulmonary resuscitation (CPR). In case you haven’t received CPR training, doctors recommend skipping mouth-to-mouth rescue breathing and doing only chest compressions (about 100 per minute). The dispatcher can instruct you in the proper methods until help arrives.
  • In the event that an automated external defibrillator (AED) is available and the person is subconscious, get started CPR while the device is retrieved and set up. Attach the device and follow instructions that will be provided by the AED after it has evaluated the person’s condition.
