Cardiac Pathologies Flashcards
Hypertrophic Cardiomyopathy (HCM)
Characterized as an abnormally hypertrophied left ventricle (over 15 mm) that causes physical obstruction of blood flow and diastolic dysfunctions
Hypertrophic Cardiomyopathy (HCM) S&S
- fatigue
- exertional dyspnea
- chest pain
- syncope or near-syncope
- increased left ventricle impulses
Hypertrophic Cardiomyopathy (HCM) Treatment
- referral
- 12-lead ECG & chest x-ray
- echocardiogram
- blood work for genetic markers
- discontinue athletic participation for at least 1 month to confirm diagnosis
- restrict participation from contact sports
Athlete Heart Syndrome
- normal adaptation to training
- long term aerobic and anaerobic exercise can lead to cardiac hypertrophy of the left ventricle
Athlete Heart Syndrome S&S
- can have ECG similar to HCM
- possible heart murmur due to increased volume and faster flow (louder with squatting / quieter with standing)
- fatigue
- exertional dyspnea
- chest pain
- syncope or near-syncope
Athlete Heart Syndrome Treatment
Decondition for 3 months and repeat ECG and echocardiogram to compare results
Sudden Cardiac Death
unexpected death due to cardiac issued
Commotio Cordis
Sudden blunt force trauma to the chest often causing sudden cardiac death in absence of cardiac damage (impact occurs during repolarization)
Commotio Cordis S&S
sudden collapse
Commotio Cordis Treatment
CPR and AED
Marfan Syndrome
A hereditable disorder that affects connective tissue (heart, lungs, eyes, arms)
Marfan Syndrome S&S
CV:
- ascending aortic dilation
- aortic dissection
- aortic regurgitation
- mitral regurgitation
- mitral valve prolapse
- abdominal aortic aneurysm
Ocular:
- superior lens discoloration
- flat cornea
- elongated globe
- retinal detachment
- myopia
- bulging eyes
Skeletal:
- anterior chest deformity (pectus excurvatum)
- scoliosis
- thoracic lordosis
- tall skinny stature
- hypermobile joints
- high-arched palate
Marfan Syndrome Screening Criteria
- wingspan greater than height
- moderate kyphoscoliosis
- heart murmur of mild systolic click
- fam hx of Marfan syndrome or sudden cardiac death before 40 y/o
Myocarditis
Inflammation of the myocardium (often due to enteroviral infections)
Myocarditis S&S
- generalized viral illness
- fever
- constitutional symptoms
- nausea
- diarrhea
- vomitting
- dyspnea
- palpitations
- syncope
- exercise intolerance
Myocarditis Treatment
immediate referral
Myocarditis Athletic Participation
- 30% are able to return to activity if there are no diagnostic issues after 6 months of removal from sport
- physical activity can trigger cardiac arrest
- should never participate with fever
- ill athletes should be discouraged from participation
Mitral Valve Prolapse
Mitral valve (between the left atrium and left ventricle) does not close properly resulting in regurgitation of blood back into the left atrium
