Heart Attack Causes

✦ Heart Disorders

Of course, the main issue of an attack is a heart disorder. In around 85% of the cases, it is found that a major or minor attack is to blame for a heart disorder.

✦ Heart Disorders That Cause Heart Attacks

  • Coronary artery disease
  • Arrhythmia
  • Deep vein thrombosis
  • Endocarditis
  • Aneurysm

✦ Diabetes

Diabetes is also one of the major reasons why people suffer from a cardiac attack which is true for about 20% of people suffering from the issue. Scientists have mostly found that people who are suffering from severe diabetes or its type-2 stage seem to be the most vulnerable.

The sugary deposits due to your excess blood glucose cause severe damage to arteries in the blood leading to its collapse and blockage which is why heart attacks occur.

✦ Hypoxia

Another issue that may not be known to many for a heart attack is hypoxia or low oxygen. As per estimates, low oxygen levels in the blood cause the heart muscles to cramp. As studies have already shown, the human muscles need energy which is derived in the presence of oxygen.

So, when the human body is in low oxygen, the heart muscles start feeling cramped and stressed which is why you suffer from an attack.

When Can Hypoxia Occur?

  • In high air pollution environment
  • In mountain tops where there is a lack of oxygen
  • Lung disease
  • Asthma
  • Some infections
  • Exposure to many gases, harmful chemical fumes

✦ High BP

High BP or hypertension is one of the major reasons people in their 40s get a heart attack. As with any other organ, the heart is supposed to bear a maximum force of blood pressure inside. If the BP is more than this the heart can behave abnormally as the tissues inside the heart are under stress which is why a heart attack can occur.

✦ Autoimmune Conditions

As per experts one of the less chances of a heart attack is having an autoimmune condition like systemic erythematosus lupus or rheumatoid arthritis. Here the immune system may act abnormally and start to attack its organ tissues. If it attacks heart cells and tissues the risk of a heart attack logically increases.

✦ Arterial Disorder

An arterial disorder like atherosclerosis may also risk an attack chance. Most of such issues cause severe damage to the walls of the artery and cause them to block or get damaged with time. As a result of this BP eventually rises which is why the attack scenario occurs.

✦ Effect Of Addictions

You may have heard from health experts and doctors that a severe form of addiction may take your own life but guess how? Yes, in a majority of patients of people severely addicted to substances you can go through a severe heart attack.

These addiction items can cause high BP, and increase cholesterol, and blood sugar, which promotes chances of a heart attack.

✦ Substances Of Addiction

  • Cigarettes
  • Vaping
  • Alcohol
  • Taking in drugs like cocaine and marijuana

Risk Factors

It is not that heart attack can only occur because of a heart disorder. There are some other things that doctors refer to as risk factors and we shall check them out.

✦ Age Age is one of the major reasons to have a heart attack. Age causes muscles to grow weaker and get imbalanced which is why an attack can occur in old age.
✦ Obesity

 

Obesity poses a major threat to your health and risks you to a heart attack.

As per science, the severe growth of fatty tissues squeezes the heart and risks the chances of a heart attack.

✦ High Cholesterol

 

A rise in bad LDL cholesterol levels can risk a major attack in the years to come. As per the report, high cholesterol above 350 can lead to an 80% chance of cardiac arrest.
✦ Family History

 

Scientists have found that people who had attacks had a family history of the disorder.

It seems that the issue can be passed down to the next generation if you have it.

✦ Bad Diet

 

There is little doubt that a bad diet can give rise to a heart attack. Food items with unhealthy fats, high carbs, and cholesterol can surely put your heart at a major risk.
