(February 13, 2026) Heart failure often develops gradually and goes unnoticed for a long time. However, the course of the disease and quality of life can be significantly improved if action is taken early.

Several million people in Germany live with heart failure, also known as cardiac insufficiency. Every year, tens of thousands of people die as a result of the disease. However, modern medicine shows that early diagnosis, consistent treatment, and an adapted lifestyle can effectively slow its progression.

What does heart failure actually mean?

In heart failure, the heart is no longer strong enough to supply the body with sufficient blood and oxygen. It therefore pumps less effectively than a healthy heart.

Typical signs are:

• Shortness of breath during exertion or even at rest
• Rapid exhaustion
• Water retention in the legs or feet
• Heart rhythm disturbances  
• Sudden weight gain within a few days
• Nocturnal urination or nocturnal shortness of breath

If these symptoms increase over a longer period of time or occur for the first time, a cardiological examination should be carried out. Prof. Dr. Dirk Westermann, Medical Director of the Department of Cardiology and Angiology at the University Heart Center Freiburg • Bad Krozingen at the Medical Center – University of Freiburg, emphasizes: "If heart failure is detected early, it can be treated effectively today –

The most common causes

The most important risk factors include high blood pressure, previous heart attacks, and arteriosclerosis. This causes fat, calcium, and cells to build up in the vessel walls. The vessels lose their elasticity – the heart has to work harder all the time and becomes weakened as a result. Chronic inflammatory processes can also damage the heart in the long term and contribute to heart failure.

Who is affected?

The disease usually develops in older age, as damaging factors have an effect over many years. In about ten percent of cases, heart failure is genetic or the result of heart muscle inflammation. In these cases, younger people can also be affected.

What I can do myself – and why it is so important

In addition to medical therapy, your own lifestyle plays a central role. Many measures can be easily integrated into everyday life:

• Check your blood pressure regularly and take your doctor's recommendations seriously
• Exercise in moderation, e.g., daily walks or adapted endurance training
• Keep an eye on your weight – rapid weight gain can indicate water retention
• Take medication reliably, even if symptoms subside

Numerous medications are available today to treat the condition, which relieve the heart, improve its performance, or treat concomitant diseases such as cardiac arrhythmias. In advanced cases, special pacemaker systems or interventional procedures can help stabilize the heart.

Early action pays off

Heart failure is a serious condition – but it is not an inevitable fate.
Those who have their symptoms checked early, consistently follow treatment recommendations, and adjust their lifestyle can positively influence the course of the disease and regain their quality of life.
