What is it?
Myocardial infarction is a complication of angina pectoris, which also causes chest pain.
In the case of angina pectoris, the coronary artery, which carries oxygenated blood to the heart, is simply narrowed. It is when it closes completely that one talks about myocardial infarction.
When the arterial wall is altered, it is called atherosclerosis. It is characterized by the formation of atheromatous plaques, composed mainly of cholesterol, cellular debris and fibers, in the artery walls, says Inserm.
Rupture of these plaques and their migration into the blood to blockade of the artery is the main cause of myocardial infarction.
What are the symptoms
In men, infarction usually begins with severe pain in the middle of the chest. The feeling of oppression, of tightness, is brutal or evolving in waves.
The pain can spread to the throat, jaws, shoulders and arms or wrists. It may be accompanied by intense fatigue, sweating, paleness, shortness of breath, palpitations, malaise or near death.
Digestive signs such as nausea and vomiting may be added, says the French Federation of Cardiology.

Symptoms that should specifically alert women are less well known: tiredness, shortness of breath, nausea or upset stomach.
Extreme case: Sudden death is a complication that appears from the first minutes with loss of consciousness and cardiac and respiratory arrest. It causes the death of 12,000 people every year in France, according to Inserm.
The time factor is crucial in case of heart disease. If you witness a discomfort, call 15. You can also learn actions that save firefighters or Civil Protection.
