Infarctus du myocarde : les 4 symptômes les plus courants !

According to the World Health Organization (WHO), myocardial infarction (MI), also known as heart attack, remains the leading cause of death worldwide.

In France, it accounts for 10% of deaths, according to 2015 figures.

MI results from oxygen deficiency in the heart muscle, the myocardium, caused by blockage of a coronary artery that supplies blood and oxygen to the heart.

According to Santé Publique France, this deprivation leads to heart failure, which then progresses to cardiac arrest. A heart attack can happen to anyone, at any time. Here are the main symptoms.

The 4 symptoms of myocardial infarction

  • Chest pain, feeling of compression or crushing in the chest,
  • Pain in arms, left shoulder, elbows, jaw and back,
  • Breathing difficulties and shortness of breath,
  • Vertigo, dizziness and malaise.

In certain situations, patients may also experience nausea, vomiting, paleness and a sensation of cold sweat.

It’s worth noting that women are more likely to experience breathing difficulties, nausea, as well as jaw and back pain.

Myocardial infarction: people at risk and risk factors

Unsurprisingly, the risk of developing a myocardial infarction (MI) increases with age.

In men, the likelihood of experiencing this increases after age 50, while in women, it occurs after age 60.

It’s worth noting that before menopause, women have a lower risk of cardiovascular events than their male counterparts.

What’s more, family history plays a crucial role as a risk factor, as do certain incurable diseases such as diabetes.

The many and varied risk factors for a heart attack include smoking, obesity, poor diet, sedentary lifestyle, lack of physical activity and excessive alcohol consumption .

Air pollution is also cited as an environmental factor likely to increase the risk of cardiovascular events.
