Overview
• Cardiovascular Adaptations to Exercise • Cardiovascular Screening • Causes of Sudden Death • Management of Arrhythmias • Management of Hypertension
Family History
• Premature death • Premature morbidity from heart disease
Family History
• Specific knowledge of:
– Hypertrophic cardiomyopathy – Dilated cardiomyopathy – Long QT syndrome – Marfan’s syndrome
Physical Examination
• • • • Blood pressure Heart murmur Arterial pulses Stigmata of Marfan’s
Athletic Heart Syndrome
• Normal Adaptations to Exercise
Athletic Heart Syndrome
• Endurance training
– Increased left ventricular chamber size
Athletic Heart Syndrome
• Strength training
– Increased left ventricular mass
Athletic Heart Syndrome
• Arrhythmia
•How slow is too slow?
Athletic Heart Syndrome
• Why is there bradycardia?
– Heart is more efficient with each beat – Greater muscle mass, greater chamber size – More blood pumped per beat
Let’s talk about sudden death
And I don’t mean overtime
Cardiac Arrest
• 400,000 people suffer out-ofhospital arrest annually • Leading cause of death in young athletes • Leading cause of death in the U.S.
Sudden Cardiac Death Causes:
• Hypertrophic cardiomyopathy • Anomalous coronary artery circulation • Marfan’s syndrome • Coarctation of the aorta • Miscellaneous
Hank Gathers (d. 1990)
If you watch the tape.
• • • • • • He goes down and nobody moves Then everybody surrounds him But does nothing An AED sat on the bench He stumbles, falls again Then he seizes
It’s horrifying
• • • • • • He is motionless His mother is standing there No one checks for a pulse No one performs CPR No oxygen No paramedics
Now we know better
Causes of Sudden Cardiac Death
• Hypertrophic cardiomyopathy
– Formerly known as IHSS
• Sickle Cell trait
– Do we screen?
• Congenital arrhythmias • Illicit drug use
Automated External Defibrillators
• 91 % of Division I universities have them • Institutions have an average of 4 devices • Placement at public sporting events is a growing trend
“Is the expense of AED’s at Division I Universities worthwhile?”
• Looked at prevalence, past utilization, and costs • 35 cases of AED use (77% in nonathletes) • Resuscitation rate was 71% • 5 arrests were in athletes, none resuscitated
• Average cost per AED was $2500 • Cost per life resuscitated was $49,000 • Estimated cost per life-year gained was $10,000 to $22,000 • Concluded that AED’s were favorable
You need an action plan.
And you need to practice it. I need 4 volunteers.
Questions you need to ask:
• Where is your AED?
– Who, if anyone, has used it? – What is its battery life? – Does it have the correct pads?
• Do you have access to oxygen? • Do you have ambulance support?
– Is it BLS or ALS capable?
More Questions:
• Who does crowd control?
– Athletes – Parents/Family – Fans – Media
• After event chaos
– Media – Documentation
You have to practice it.
• Your eyes are on the game • Look for altered behavior • Delegate jobs
– AED, pulses – Airway – CPR – Coordinate with EMS
More Practice
• What about away games? • Discussion with team • After-event decompression
Take Home Points
• Cardiac arrest is leading cause of death in young athletes • It is still rare • AEDs are useful • Have an action plan and practice it
Let’s talk about the other causes…
Hypertrophic Cardiomyopathy
• Thickened, non-dilated left ventricle
– >15 mm septal wall
• Autosomal dominant • Deranged cellular architecture leads to conduction problems
Hypertrophic Cardiomyopathy
• May not be evident until late teens
Hypertrophic Cardiomyopathy
• Physical exam
– Systolic murmur
Systolic Murmur
• Accentuated with Valsalva maneuver
• Decreased with squatting
Hypertrophic Cardiomyopathy
• Chest X-ray
• Cardiomegaly
Hypertrophic Cardiomyopathy
• What actually causes death?
Hypertrophic Cardiomyopathy
• Diagnosis
– History – Physical exam – EKG – Echocardiogram
Anomalous Coronary Artery Circulation
• Congenital abnormalities of the Arteries
– Single coronary artery – Smaller arteries – Common origin of the arteries
Anomalous Coronary Artery Circulation
• History
– Poor perfusion of the heart with exercise
Anomalous Coronary Artery Circulation
• Physical exam
– No consistent findings
Anomalous Coronary Artery Circulation
• Diagnosis
– Autopsy – Angiography
Marfan’s Syndrome
• Connective tissue disorder • Autosomal dominant trait • Fibrillin gene
Marfan’s Syndrome
• Physical exam findings
– Tall body habitus (wingspan greater than height) – Hyperextending joints – Arachnodactyly
Marfan’s Syndrome
• Physical exam findings
– Pectus excavatum – Scoliosis – Subluxed lens
Marfan’s Syndrome
• What causes sudden death?
• Aortic dissection
Marfan’s Syndrome
• Can they compete?
– Avoid contact sports, isometrics, weights, exhaustive exercise – Consider noncompetitive swimming, biking
Coarctation of the Aorta
• Congenital • Often a pediatric diagnosis
Coarctation of the Aorta
• Classic findings
– Radial pulses greater than pedal pulses – Uneven radial pulses
Coarctation of the Aorta
• Definitive treatment before allowing participation
Cardiac Screening
• Family history of heart problems • Family history of sudden cardiac death before age 50 • Easy tiring, legs before arms, can’t keep up with teammates • Dizzy • Chest pain, shortness of breath, palpitations, drug use • Ever been disqualified by a physician before?
Why is hypertension such a big deal?
What are the numbers you are looking for?
140/90
Hypertension
• Risk Factors

When in doubt, keep them out.
Let’s switch gears.
MRSA infections
• • • • • What are they? Why are they such a big deal? Who here has seen them? Who is getting them? What are we going to do about them?
Methicillin Resistant Staphlococcus Aureus
• A community acquired bacteria that is running rampant • Now occuring in healthy, young, active people • Easily spread • If you don’t treat it…it can get ugly, and be fatal
Why should you care?
• Because your athletes, and even yourself could be affected • The infections are spread person to person
– Whirlpools – Shared towels, soaps – Equipment (weights, pads) – Artificial turf
What do they look like?
• Starts out as “no big deal” • Abrasions, turf burn, a “spider bite” • But different… • Skin is red, hot, and looks angry • There can be an abcess, or pustules • And they hurt
Case 2
“This thing hurts”
Photo
“This thing is nasty and smelly.”
What is it? What do you do?
MRSA
• The infections progress rapidly, within 24 - 48 hours • You choose different antibiotics than a typical cellulitis • And they need to scrub with an anti-bacterial soap (Lever 2000) • They may need to be drained • Then…
There are carriers.
• Close contacts (household, team mates) • Need bactroban ointment inside their noses • Twice a day for 7 - 10 days • And you need to be hypervigilant with your treatment areas
Oooooh…scary.
Kazakova SV, et al. A Clone of MRSA Among Professional Football Players, NEJM. 2005; 352(5): 468-75.
• CDC descended onto the St. Louis Rams practice facility • 9% of the players had MRSA infections at turf abrasion sites • No MRSA found in nasal or enviromental samples • MSSA recovered from whirlpools, taping gel, and 42 % of the noses of players and staff
Kazakova, et al.
• Abcesses of the same clone of bacteria were then isolated from a competing team (49ers), suggesting game transmission • CDC initiated a collaboration with the NCAA in developing guidelines for prevention and control MRSA…”targeted for athletic trainers”
What else?
• 130,000 people are hospitalized with MRSA each year… • “It’s an emerging epidemic”, says Dr. Gonzalo Ballon-Landa, president of Infectious Disease Association of California • 50% of staph infections seen in CA hospitals are MRSA • All it takes is a small opening in the skin for MRSA to finds its way into the bloodstream
Like this…
• Athlete has a cut or an abrasion…you bandage it • He/She practices, comes into the locker room or shower…. • Throws bandage on the ground • Someone with bare feet steps on it • Now it’s shared
What do you do?
• Wash hands regularly…and often. Go with anti-bacterial option • Cover ALL wounds, even small ones. Throw old band-aids away • Monitor any abnormality in the skin closely • Don’t share towels, or gear. Wipe down all equipment and weight machines
Back to Case 2
The Abrasion
• Cover it! • Educate them on taking care of band-aids…and their disposal • Wound checks every day • Emphasize not sharing towels, and cleaning all surfaces
The Abscess
• It will be drained • And cultured • And antibiotics given…likely Septra, or Rifampin/Clindamycin • Use Lever 2000 soap • Bactroban nasal ointment for household/close contacts
Case 3
“I don’t feel too hot.”
• 19 year old female complains of a fever • Achy, runny nose, cough • Roommate has the same thing • Looks miserable…
– Temp = 101.2, HR = 110
What do you do with her?
What temperature is a “fever”?
100.5 and above
In general
• Mild to moderate exercise may enhance the immune system • If you overdue it…you can put it down • Fevers will decrease strength, aerobic power, endurance, coordination, and concentration….
All of this can lead to injury
Effect of fever on physiology
• Increased cardiopulmonary effort with reduction in peak exercise capacity • Abnormal temperature regulation • Abnormal lung function • Early muscle fatigue • Just sucks mentally
General Recommendations
• Avoid strenous conditioning and competition during febrile state (100.4) • Symptoms above the neck: go at 50% for a few mintues, increase the intensity if they clear • Symptoms below the neck: no training
What could the fever be from?
• • • • • • • • A cold…URI Mononucleosis Pneumonia Meningitis Gastroenteritis Pharyngitis/Strep Bladder infection STD
Upper Respiratory Tract Infections
• Fever, chills, aches, sore throat, fatigue, cough • Bugs: rhinovirus, adenovirus, coxsackie…VIRUS • Treat: rest, fluids, antipyretics…watch over the counter meds… • Big can of suck it up
Pharyngitis
Pharyngitis
• Signs & Sx: fever, sore throat, swollen/ exudative tonsils, anterior cervical LAN • Group A beta-hemolytic Strep • Rapid Strep tests 85-90% accurate • Throat Culture 95% accurate • Tx: PCN, E-Mycin, or Clinda; fluids, rest, analgesics • Return once afebrile & on antibiotics
Infectious Mononucleosis
Infectious Mononucleosis
• 90% of people EBV + by age 30 • Oral transmission • “Classic Syndrome” is headache, fever, anorexia, giant lymph nodes, malaise, aches, sore throat • What do you have to worry about?
Big fat spleen
It likes to bleed. And bleed. And that is bad.
Splenic Rupture
• Usually will occur on days 4 - 21 of illness • It can occur with very minor trauma…even day to day things • Left upper quadrant pain, low BP, high HR • Prompt surgical referral
Infectious Mononucleosis Treatment
• • • • Symptomatic care Stool softeners? Corticosteroids? When can they play?
– Afebrile, symptoms resolved – Get an US if any questions – Start with gradual non-contact activity and slowly progress – Most well in 4-6 weeks, some 3-6 months
Pharyngitis vs Mononucleosis
• • • • Exudative tonsillitis Lymphadenopathy Myalgias Lab tests
Pneumonia
• Symptoms: fever, chills, cough, short of breath, fatigue, chest pain • Can be viral or bacterial • Diagnosis confirmed with CXR • Treat with fluids, rest, antibiotics • Return: when afebrile, symptoms resolved
The pukes and the runs
• SUPER contagious…you ate poop • Symptoms: nausea, vomiting, diarrhea, cramps, fever • Causes: TONS of viral, bacterial, parasitic • Treatment: supportive • Who needs an IV?
Archives Ped Adol Med, 5/2004
• Enteral versus IV rehydration in adolescents in gastroenteritis • 16 randomized controlled trial, 11 countries • Looked at weight gain, a decrease in diarrhea • Go by mouth!
The Unmentionables
HIV, Hepatitis B and C, other STDs
Bottom Line
• They’re all on the rise… • Prevention and education are key • Transmission:
– HIV, Hepatitis B and C: Blood borne – HIV, Hepatitis C: Sexual activities
• Body fluids: blood, semen, vaginal secretions, breast milk, amniotic fluid
Bottom Line
• Other fluids: tears, sweat, urine, sputum, saliva, vomit… • Unless they have blood in them • Transmission in sports is very very very low • Use universal precautions
Some questions for you…
• How often do athletes report STD symptoms to you? • What is your referral system…is it the student health center? • Do you have a reporting system?
Immunizations
• Tetanus: Booster every 10 years, or give if has wound and > 5 years since last booster. • Influenza: annually if supplies adequate, no contraindications, lasts 1 yr in healthy people, 25-50% sore @ site, 1% fever & myalgias. • Measles and Pertussis: outbreaks recurring! See guidelines. • Hepatitis B: no clear recommendation for athletes
Skin Quiz
Name it.
Impetigo
Drug eruption
Chicken Pox
Hives
Cold sore…Herpes
Athlete’s Foot/Tinea Pedis
Take Home Points
• Counsel your athletes • Avoid overtraining and chronic fatigue • Keep immunizations up to date • Avoid ill people…rashes too • WASH YOUR HANDS
