Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol intake, among others. The mechanism of an MI often involves the complete blockage of a coronary artery caused by a rupture of an atherosclerotic plaque.

MIs are less commonly caused by coronary artery spasms, which may be due to cocaine, significant emotional stress, and extreme cold, among others.
The only problem is people either ignore the signs of fail to recognise it. Here are 6 signs you should never overlook.

Pressure On Your Chest Region
Chest pains and pressure is a sign that most people are relatively aware of, but maybe you should take any chest pressure more seriously than you have in the past, as it could just be a very real indication of an impending heart attack.

Having Flu Or Common Cold Symptoms
It is a known fact that some people experience flu like symptoms prior to having a heart attack, you should take a visit to your doctor if you have cold or flu symptoms, for a thorough checkup.
Unexplained Weakness

As your blood vessels narrow out, blood flow is inhibited greatly and this causes the supply of oxygen to your vital organs and brain to be depleted, leading to unexplained weakness.

Chronic Fatigue
With limited blood flow and circulation in your entire body and brain, as well as the shortage of oxygen, you are likely to experience chronic fatigue and a general lack of energy.

Dizziness And Cold Sweats
When your blood circulation is inhibited due to narrow blood vessels, your brain gets less supply of oxygen causing you to feel dizzy and have cold sweats.

Having A Shortness Of Breath
If you experience shortness of breath, it means that the supply of oxygen to your lungs is hindered, this also affects the volume of oxygen conveyed by your blood to heart as well. You need to seek medical advice if you experience shortness of breath.
