Heart failure is the inability of the heart muscle to normally propel blood through the body. It can occur in the evolution of myocardial infarction, angina, high blood pressure… Its frequency increases with age.(1)
The heart of a patient with heart failure has lost muscle strength and normal contraction capacity; it no longer pumps enough blood to allow the organs to receive enough oxygen and nutrients, essential to their proper functioning (1).
In France, heart failure affects 2.3% of the French adult population and 10% of people over 70, or more than one million people (1).
Heart failure is a major cause of death in France regardless of age. It was directly or indirectly responsible for more than 70 000 deaths (1).
There are several possible causes for heart failure:
Ischemic heart disease (myocardial infarction, angina pectoris), which is the main cause of heart failure (1).
High blood pressure (i.e. too high blood pressure), which is the second leading cause of heart failure (1).
Heart rhythm disorders, including atrial fibrillation, heart valve abnormalities and heart muscle diseases that are rarer causes (1).
