Your Heart — Clearly Explained

Common questions patients ask about heart disease, angioplasty, hypertension, and sports cardiology.

  • Why is early medical screening important for athletes?

    Because it:

    • Reduces the risk of sudden cardiac complications

    • Detects silent diseases without symptoms

    • Protects the athlete from unexpected risks

    • Ensures safe and confident sports participation

    📌 An athlete may appear healthy, but some heart conditions only appear during medical testing.

  • Is medical screening necessary even if the athlete has no symptoms?

    Yes. Many serious conditions:

    • Do not cause symptoms

    • Are only detected through medical examination

    • May appear for the first time during intense exertion

    For this reason, early screening is considered preventive, not therapeutic.

  • What does early medical screening include?

    It usually includes:

    • Personal and family medical history

    • Complete clinical examination

    • Electrocardiogram (ECG)

    • Echocardiography (Echo)

    • Exercise testing when needed

    • Additional tests depending on the type of sport and the athlete’s age

  • Does medical screening differ depending on the type of sport?

    Yes. Screening varies according to:

    • Type of sport (endurance – strength – contact)

    • Intensity of exertion

    • Athlete’s age

    • Level of competition

    📌 There is no single screening suitable for all athletes.

  • What is the relationship between early screening and prevention of sudden cardiac death?

    Early medical screening is the most globally recognized method for reducing cases of sudden cardiac death in athletes because it helps detect:

    • Cardiomyopathy

    • Heart rhythm disorders

    • Congenital heart defects

    • Early coronary artery problems

  • When should an athlete undergo medical screening?

    • Before starting any regular sports activity

    • Before participating in competitions

    • When changing the level or intensity of training

    • After injury or long interruption from training

    It is preferable to repeat it periodically.

  • Is early medical screening only for professional athletes?

    No. It is also important for:

    • Amateurs

    • Academy players

    • Youth athletes

    • Older athletes

  • Does medical screening prevent the athlete from practicing sports?

    On the contrary, the goal of screening is to:

    • Choose the appropriate sport for each athlete

    • Adjust training intensity when needed

    • Allow safe participation instead of unnecessary restriction

  • What happens if a health problem is detected?

    In this case:

    • The condition is carefully evaluated

    • A treatment or follow-up plan is established

    • A safe activity level is determined

    • Sports participation may be allowed with special precautions

    📌 Early detection prevents complications and protects the athlete’s future.

  • Is early medical screening safe?

    Yes. All tests are:

    • Non-painful

    • Safe

    • Conducted according to approved medical standards

  • Why should screening be performed under the supervision of a sports cardiology specialist?

    Because interpreting results requires:

    • Expertise in exercise physiology

    • Understanding normal athlete heart adaptations

    • Differentiating between athletic adaptation and disease

  • Is early medical screening an investment or a routine procedure?

    Early medical screening is:

    • An investment in the athlete’s health

    • Protection for the athletic future

    • An essential step for safe and professional practice

    Safe sports begin with proper medical screening.

  • What is a CPET device?

    The CPET (Cardiopulmonary Exercise Testing) device is the most accurate and comprehensive medical test for evaluating the efficiency of the heart, lungs, circulation, and muscles during physical exertion.

    It is considered the global gold standard for measuring fitness and functional capacity under real physical stress.

  • How does the CPET device work?

    The person performs gradually increasing exercise on a stationary bicycle. During the test:

    • ECG and blood pressure are continuously recorded

    • Breathing and gas exchange (oxygen and carbon dioxide) are measured through a special mask

    • The body’s systems are analyzed moment by moment

    The test is completely safe and conducted under specialized medical supervision.

  • What is the difference between CPET and a regular stress ECG test?

    A stress ECG monitors heart rhythm changes during exertion, whereas:

    • CPET evaluates the heart, lungs, and muscles together

    • Identifies the precise cause of poor performance or fatigue

    • Differentiates between cardiac and pulmonary causes of shortness of breath

    • Determines whether reduced fitness is due to the heart, lungs, or muscles

    • Provides data that cannot be obtained from any other test

    Therefore, CPET is completely different from a standard stress ECG test.

  • What makes our CPET device unique?

    • The first and only device in Egypt

    • Used in a specialized and systematic way

    • Operated and interpreted by a consultant cardiologist and sports specialist

    • Compliant with the latest international guidelines and standards

  • What is VO₂max?

    It is the maximum amount of oxygen your body can use during exertion.

    Simply put:
    It is the true number of your fitness level.

  • Why is VO₂max the most important number in your health?

    Studies have shown that VO₂max is:

    • The strongest indicator of longevity

    • The strongest predictor of cardiovascular mortality

    • A direct indicator of brain health and reduced Alzheimer’s risk

    • More important than weight or body shape

    📌 VO₂max reveals the truth.

  • Why can VO₂max only be measured accurately by CPET?

    • Smartwatches provide inaccurate estimates

    • Theoretical calculations are misleading

    • CPET is the only precise and scientifically approved method

  • Is CPET useful for athletes?

    Yes. It helps with:

    • Accurate scientific performance evaluation

    • Determining the maximum safe exertion level

    • Designing individualized training programs based on real data

    • Reducing injury risk through proper heart rate and load zones

    • Preventing Overtraining Syndrome

    We are not just a device — we are a complete system for diagnosis, training development, and performance improvement.

  • What is Lactate Threshold?

    Lactate Threshold is the stage during physical exertion at which muscles can no longer efficiently use oxygen to produce energy. At this point, the body shifts to faster, less efficient energy systems, leading to lactate accumulation in the muscles.

  • What does “Hitting the Wall” mean?

    Professional athletes describe this phase as “Hitting the Wall,” which is the moment when:

    • Muscles feel extremely heavy

    • The athlete cannot maintain the same speed

    • Performance suddenly drops despite strong effort

    This occurs because muscles can no longer use oxygen efficiently to sustain energy production.

  • Is CPET used after injuries?

    Yes. It is essential for:

    • Assessing readiness to return to play

    • Determining real endurance levels after injury

    • Reducing the risk of re-injury

  • Is CPET useful for non-athletes?

    Yes. It is used to evaluate:

    • Sedentary individuals

    • Elderly people

    • Heart and lung patients

    • Obesity and diabetes patients

  • Does fitness affect longevity?

    Yes. Scientific studies show that cardiorespiratory fitness is one of the strongest indicators of longevity and reduced mortality, regardless of age or weight.

  • Can fitness be improved after measurement?

    Absolutely. With CPET:

    • We measure fitness accurately

    • Identify weak points

    • Create a gradual personalized program

    • Reassess later to measure real improvement in numbers

    📌 What cannot be measured accurately cannot be improved correctly.
