Heart attacks (medically termed myocardial infarctions) are common medical emergencies worldwide. Each year, in Australia around 57,000 individuals have heart attacks. Almost half of the population of Australia is at a risk for heart disease, and the numbers are rising. Fortunately, by familiarizing yourself with the causes, symptoms, and risk factors, you can lower the chances of experiencing a heart attack. The informative blog post will take a closer look at how heart attacks occur, and how to diagnose, treat and prevent them.

What Exactly Is A Heart Attack?

Commonly known as a myocardial infarction, a heart attack is a common cause of death globally. To function properly, your heart needs a continuous blood supply. Heart attacks happen when there’s a build-up of plaque made of fat, cholesterol, and other substances that block or cut off the flow of blood to the heart muscles. The interruption of in the blood supply can destroy or damage part of the heart tissue, leading to heart failure and other serious complications. So, at the most basic level, heart attacks mean that the heart is not receiving enough blood flow.  

As already covered above, more than 57,000 Australians experience a myocardial infarction each year. It is a life-threatening emergency that requires immediate medical help. The earlier the sufferer receives medical attention, the lesser the damage. A heart attack can be fatal, but treatment options for heart diseases and heart attack have dramatically improved over the past few years.

What is the Causes Of Heart Attacks And Stroke

Most heart attacks happen because of a blockage in one of the coronary arteries. Also known as atherosclerosis, coronary artery disease (CAD) is one of the common causes of heart attacks. The build-up (also known as plaque or atheroma) of unwanted fatty substances like cholesterol in the arteries is termed atherosclerosis. If a portion of build-up cracks or breaks off, it will form a blood clot which can block the artery, causing a heart attack. 

The risk of developing coronary artery disease (CAD) is increased by: 

  • Being overweight or obese 
  • High cholesterol 
  • Smoking 
  • Diabetes 
  • A high-fat diet 
  • High blood pressure (hypertension) 

Other less common causes of heart attacks include the following: 

  • Drug misuse 
  • Hypoxia (sudden drop in oxygen levels) 
  • Spontaneous coronary artery dissection or SCAD (a condition where multiple coronary arteries break off) 

Who Has A Higher Risk Of Heart Attacks?

A heart attack does not discriminate and heart-related issues affect both men and women. However, heart attacks or myocardial infarctions in females tend to be fatal as they get older. People with obesity and Type 2 diabetes are more prone to develop heart-related problems.   

Several other health conditions, your age, your lifestyle and your family history can also put you at a higher risk for heart-related issues and heart attack. Most people have one of these key risk factors for a heart-related issue: smoking, high blood pressure and high blood cholesterol. Although some risk factors for heart disease and heart attack cannot be controlled such as family history or age, precautionary steps can be taken to reduce the risk of heart disease.
