Cardiology · Sports Medicine · Prevention
Before leaving health and training to chance, you should know where you stand.
Preventum Diez combines cardiology, sports medicine, and clear medical advice.
Do you want to start exercising, become more active again, find a safe return to movement after illness, or specifically improve your performance? The first step is not speed. The first step is clarity.
Clarity before exercise
Want to live healthier? Then don't just start jogging. Start with clarity.
- —
Sports are important. Exercise can protect, strengthen, stabilize, and enable new performance.
- —
But starting blindly is not prevention. You shouldn't have to guess how healthy you are.
- —
A lot can be measured, classified, and clearly explained.
- —
If you want to remain healthy through sports for longer, regain confidence after illness, or specifically improve your performance, you should know if you are training correctly.

Read moreWho is Preventum Diez for?
The common denominator is not age. The common denominator is responsibility for one's own body.
Preventum Diez is not limited to a specific age group. The question at hand is what determines the course of action.
In the presence of risk factors
High blood pressure, family predisposition, elevated blood fats, overweight, stress, or uncertainty before exertion.
After cardiac event
For patients after a heart attack, stent, bypass, rhythm disturbances, or other heart disease.
Young adults
Those who want to know before intense training if everything is okay.
Amateur & Professional Sports
Ambitious athletes who want to better understand heart, circulation, respiration, recovery, and resilience.
Prevention-Oriented
Anyone who takes sport, movement, or performance seriously shouldn't guess their resilience.
Prevention and Secondary Prevention
Prevention is not just about avoiding diseases. It means planning the next step consciously.
Primary prevention is aimed at people who want to recognize risks early before serious symptoms occur.
Secondary prevention is especially important for people who have already experienced a heart attack, coronary artery disease, stent placement, bypass surgery, arrhythmias, or other cardiovascular diseases.
In these cases, exercise is often a crucial part of the further path. However, it should match the current cardiovascular situation.
Sports Medicine and Competitive Sports
Not only start safely. Also train more effectively.
Preventum Diez also addresses people who train regularly, pursue ambitious goals, or are active in competitive sports. Those who demand a lot from their bodies should understand how the heart, circulation, breathing, metabolism, and recovery interplay.
Dr. Kirchner understands this perspective personally as well: He himself engaged in competitive sports as a young person.
What is examined?
A good picture is not made by a single value.
Whether and which examinations are useful depends on your medical history, symptoms, and objective.
Discussion and medical history
Family history and risk factors are assessed.
Blood Pressure, Metabolism, Laboratory
Values are viewed as part of the whole picture — not in isolation.
Resting ECG & Stress
Reaction of heart, circulation, and blood pressure at rest and under stress.
Echocardiography
Structure and function of the heart.
Spiroergometry
Breathing, oxygen uptake, and performance combined.
Nutrient status & more
When resilience, fatigue, or performance is the primary concern.
Endurance
Resilience develops not only in training.
- —
Sleep, nutrition, metabolism, recovery, and inflammatory processes can also play a role.
- —
Micronutrients and mitochondrial energy supply influence the response to stress.
- —
Depending on the initial situation, an extended portfolio can be sensible — as an individual supplement, not as a standard program.
- —
What is important: Not every procedure is meaningful for every person. Diagnosis, objectives, and medical situation decide.
