What is the recommended medical evaluation for a young individual with a history of medical conditions prior to participating in sports or physical activities?

Sports Physical Evaluation for Young Athletes

Young individuals seeking sports participation should undergo a structured preparticipation physical evaluation (PPE) that includes a comprehensive personal and family cardiac history, focused physical examination emphasizing cardiovascular, musculoskeletal, and neurologic systems, and selective use of 12-lead ECG based on risk factors or concerning findings. 1, 2, 3

Core Components of the Evaluation

Medical History Assessment

The history is the most critical screening tool and must include specific cardiovascular red flags:

Personal History:

• Chest pain, discomfort, tightness, or pressure related to exertion 2
• Unexplained syncope or near-syncope episodes 2
• Excessive dyspnea, fatigue, or palpitations with exercise 2
• Prior heart murmur recognition or restriction from sports 2
• History of prior cardiac testing 2

Family History:

• Premature sudden cardiac death before age 50 in any relative 2
• Disability from heart disease in close relatives under age 50 2
• Specific genetic cardiac conditions including hypertrophic cardiomyopathy, dilated cardiomyopathy, long-QT syndrome, ion channelopathies, or Marfan syndrome 2

Critical Point: Parents should complete the history form for minors, as young athletes may lack the medical knowledge or compliance to provide accurate responses 1

Physical Examination Focus

Cardiovascular Assessment:

• Blood pressure measurement in sitting position, both arms 4, 2
• Heart rate, rhythm, and orthostatic vital signs 2
• Comprehensive auscultation for heart sounds (S1, S2, S3, S4) and murmurs with attention to timing, location, radiation, intensity, and quality 2
• Femoral pulse assessment to exclude aortic coarctation 2
• Physical stigmata of Marfan syndrome (tall stature, arm span exceeding height, pectus deformity, arachnodactyly) 2

Musculoskeletal Examination: This is the second most important component, as musculoskeletal problems are the leading cause of sports restriction (43.4% of disqualifications) 5. The examination should be performed by qualified personnel and assess joint stability, range of motion, and prior injury sequelae 5

Neurologic Assessment: Screen for concussion history and neurologic deficits 3

Ancillary Testing

12-Lead ECG:

• Not routinely required for all athletes in the United States, unlike European protocols 1
• Should be obtained when history or physical examination reveals concerning findings 2
• Consider for athletes with significant family history of sudden cardiac death or genetic cardiac conditions 2
• Mandatory for older athletes (men ≥40 years, women ≥55 years) with ≥2 coronary risk factors who wish to engage in vigorous competitive sports 1

The American Heart Association does not recommend mandatory ECG screening for all young athletes due to concerns about false-positive results leading to unnecessary testing, anxiety, and unwarranted disqualification 1. However, this remains controversial, as European guidelines advocate universal ECG screening 1

Additional Screening Considerations

Mental Health: Screen for depression, anxiety disorders, and attention-deficit/hyperactivity disorder 3

Relative Energy Deficiency in Sport (RED-S): Recognize signs including menstrual irregularities, stress fractures, and disordered eating patterns 3

Special Populations:

• Transgender athletes require individualized assessment 3
• Athletes with physical or intellectual disabilities need adapted evaluation 3

Timing and Setting

Optimal Timing: Perform the PPE 6 weeks before the competitive season to allow adequate time for treatment and rehabilitation of identified problems 6

Preferred Setting: The evaluation should occur in the physician's office rather than mass screening settings, as this allows for better privacy, more thorough examination, and appropriate follow-up 1, 3

Clearance Decision Algorithm

Full Clearance (No Restrictions):

• Normal history, physical examination, and any indicated testing 3, 5
• Approximately 86% of athletes receive full clearance 5

Clearance with Follow-Up:

• Minor abnormalities identified that don't preclude participation but require monitoring 5
• Examples: mild hypertension, minor musculoskeletal issues, visual acuity problems correctable with lenses 7, 5
• Approximately 12% of athletes fall into this category 5

Disqualification (Temporary or Permanent):

• Life-threatening cardiac conditions (see specific conditions below) 1
• Uncontrolled hypertension 7
• Significant musculoskeletal instability or injury 5
• Approximately 2% of athletes are disqualified 5

Special Considerations for Genetic Cardiovascular Diseases

For athletes with known genetic cardiovascular diseases (GCVDs), specific activity restrictions apply:

Hypertrophic Cardiomyopathy (HCM):

• Avoid high-intensity sports (basketball, ice hockey, soccer, sprinting) 1
• May participate in low-intensity activities (bowling, golf, brisk walking) with scores of 4-5 on the acceptability scale 1
• Avoid isometric exercises like free weight lifting due to Valsalva-induced outflow obstruction 1

Long QT Syndrome (LQTS):

• Avoid water-related activities (swimming, surfing) due to risk of impaired consciousness 1
• Restrict high-intensity burst activities 1
• Low-intensity activities generally acceptable 1

Marfan Syndrome:

• Avoid contact sports and activities with risk of aortic trauma 1
• Avoid isometric exercises that increase aortic wall stress 1
• Competitive sports strongly discouraged if Ghent criteria met 1
• Low-intensity leisure activities may be appropriate for skeletal health 1

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC):

• Restrict high-intensity competitive sports 1
• Moderate activities may be acceptable on individual basis 1

Brugada Syndrome:

• Avoid activities that significantly increase body temperature, as this can trigger arrhythmias 1
• High-intensity sports generally discouraged 1

Congenital Heart Disease Considerations

Repaired Tetralogy of Fallot:

• Requires evaluation including clinical assessment, ECG, imaging of ventricular function, and exercise testing before sports participation 1
• Clearance depends on residual ventricular function and absence of significant arrhythmias 1

Post-Atrial Switch (Mustard/Senning) for Transposition:

• Athletes with ejection fraction >50%, no arrhythmias, and no outflow obstruction may participate in moderate to high-intensity sports if exercise testing shows no concerning findings 1
• Those with severe RV dysfunction or uncontrolled arrhythmias should be restricted to low-intensity (class IA) sports only 1

General Principle for CHD:

• Athletes with normal or near-normal systemic ventricular function (EF ≥50%) can participate in all sports 1
• Mildly diminished function (EF 40-50%) allows low and medium-intensity sports 1
• Moderately to severely diminished function (EF <40%) restricts to low-intensity sports only 1

Common Pitfalls to Avoid

Inadequate Examiner Qualifications: The American Heart Association strongly opposes the practice in 18 states allowing chiropractors or naturopaths to perform PPEs, as they lack formal training for cardiovascular screening 1. Only physicians or properly trained nurse practitioners/physician assistants should perform these evaluations 1

Insufficient Auscultation: Perform cardiac auscultation in a quiet environment with proper technique, as inadequate assessment can miss significant murmurs 2

Overlooking Family History: Sudden cardiac death in young athletes often occurs in those with unrecognized genetic conditions, making family history critical 1, 2

False Reassurance: Standard history and physical examination cannot reliably identify all potentially lethal cardiovascular abnormalities 1. Maintain appropriate clinical suspicion and low threshold for referral to cardiology when concerns arise 1

Ignoring Musculoskeletal Issues: Since musculoskeletal problems are the most common cause of sports restriction, this component requires thorough evaluation by qualified personnel 5

Who Should Perform the Evaluation

Preferred Examiners:

• Licensed physicians with cardiovascular screening training 1
• Nurse practitioners or physician assistants with formal training in physical examination techniques and standardized certification for athletic screening 1

Unacceptable Examiners:

• Chiropractors or naturopathic clinicians, who lack requisite medical training 1

Referral Indications

Refer to cardiovascular specialist when:

• Abnormal cardiac history or examination findings identified 1, 2
• Significant family history of sudden cardiac death or genetic cardiac disease 2
• Abnormal ECG findings if obtained 2
• Any uncertainty about cardiovascular safety for sports participation 1
