In the pharmacy queue, a blood pressure cuff sits on the counter, almost forgotten. Someone pauses by, a touch out of curiosity, convinced that the heart is fine. No shortness of breath, no pain, no alarm signals. And yet, behind this apparent calm, there can sometimes lie a ticking time bomb. Each year in France, this disease strikes an adult once in three without warning, and ends up claiming tens of thousands of lives. How can a condition so invisible weigh so heavily in national mortality statistics? The answer rests in one word that many people know little about: hypertension.
- Hypertension affects 17 million French people, about one in three adults, often with no visible symptoms
- It is responsible for more than 55,000 deaths and up to 500,000 hospitalizations per year in France
- It increases the risks of stroke, heart attack, kidney and heart failure, as well as dementia
- Hypertension, the threat that never says its name
- Numbers that make your head spin: when blood pressure kills more than we think
- Heart, kidneys, brain: a killer with many faces
Hypertension, the threat that never says its name
High blood pressure affects roughly 17 million French people, that is, one in three adults in the country. Its standout trait, if one can call it that, is its discretion. No characteristic pain, no unusual fatigue, nothing to raise alarm. Only hypertensive crises, when the numbers rise above 200 mmHg, produce visible symptoms. In the meantime, the condition progresses quietly, year after year, without drawing attention. This is precisely why the World Health Organization calls it a silent killer: it acts without noise, but its consequences are anything but quiet.
Numbers that make your head spin: when blood pressure kills more than we think
For the first time, Santé publique France published a study precisely quantifying the real burden of this disease in the country. The verdict is unequivocal: hypertension would be responsible for more than 55,000 deaths in 2021 and about 400,000 hospitalizations. Some estimates even place the figure at up to 500,000 hospitalizations linked to this condition each year, i.e., 8.5% of all deaths in France. On a global scale, hypertension would be involved in eight million deaths each year, including those 55,000 French lives. In other words, almost one death in ten in the country would be connected, directly or indirectly, to poorly controlled blood pressure.
Heart, kidneys, brain: a killer with many faces
Claire Mounier-Vehier, a cardiologist at the Lille University Hospital, aptly summarizes the situation by referring to it as a true “silent killer.” And for good reason, hypertension does not only attack the heart. It also weakens the kidneys and increases the risk of certain neurodegenerative diseases. Among the most feared complications are:
- strokes
- dementia disorders
- myocardial infarction
- heart failure
- kidney failure
In the face of this worrying picture, screening campaigns have been available in pharmacies and supermarkets since 2019. But the reach remains modest: only 5,000 people were able to benefit, due to a lack of mobilized staff. Yet the results are revealing: more than 30% of those screened had elevated readings, and 7% had never undergone a blood pressure check in their life. At a recent meeting of the French Society of Hypertension, specialists warned of a deterioration in management in France, a paradox given that screening tools do exist.
In light of this, vigilance remains the best available weapon. Regularly monitoring one’s blood pressure, adopting a suitable lifestyle, and consulting at the first signs of risk can often prevent the worst. A simple cuff, a few minutes, and perhaps a life saved: prevention has never seemed so accessible, provided it is no longer neglected.
