It affects nearly one in three adults in France. But due to lack of symptoms and sufficient screening, four out of ten patients are unaware of being affected.

From then on, all organs will be less well irrigated, resulting in a risk of damage to the heart (infarction), eyes (retinopathy), kidneys (renal failure), etc. In addition, the covering of the aorta can tear: this is aortic dissection, a life-threatening emergency. Finally, the arteries are likely to become blocked, as a result of a process involving inflammatory cells and lipids, leading to stroke or myocardial infarction. And the heart, having to work harder, ends up tiring (heart failure).

To avoid getting to that point, Éric is treated, like around 11 million French people. There are several families of medications available (angiotensin II receptor antagonists, angiotensin converting enzyme inhibitors, diuretics, beta-blockers, etc.) and as Professor Potier indicates, “as soon as you control your blood pressure blood pressure, cardiovascular risk decreases very quickly. It nevertheless points out the harmful effects of hyperglycemia, the effects of which on the arteries persist.
