Sudden Death • About 25 young patients die each year nationally in sudden-initially unexplained deaths on the field in all sports ~ usually heart related. • Usually hypertropic cardiomyopathy or congenital abnormalities • 10:1 ratio male to female • Football & Basketball see the highest incidents.
Definition • Sudden Death: • 90% collapse during or after activity • 62% High School Age
Causes of Sudden Death • Hypertrophic Cardiomyopathy (HCM) • Aortic Stenosis • Congenital Coronary Artery Anomalies • Marfan Syndrome • Mitral Valve Prolapse
Hypertrophic Cardiomyopathy • Definition • Can occur c or s obstruction • What happens then?
Hypertrophic Cardiomyopathy cont. • Clinical Presentation: • History • Physical Exam • The first clinical presentation of this condition may be sudden cardiac death!
Hypertrophic Cardiomyopathy cont. • Diagnostic tests: • Bethesda Guidelines – HCM • Patients with unequivocal diagnosis of HCM should not participate in most competitive sports with possible exception of low intensity sports (i.e. BOWLING)
Coronary Artery Abnormalities • Presentation: • The 1st clinical presentation of this condition may sudden cardiac death! • Diagnostic Tests:
Marfan Syndrome • 5% of death due to rupture of aortic valve • Abe Lincoln • Clinical physical signs: • Bethesda Guidelines – Marfan’s • Patients s a family hx of sudden death & s aortic root dilitation ca participate in low & moderate intensity sports
Rare causes of Sudden Death • Long QT Syndrome: electrical abnormality • Bethesda Guideline: QT • Restrict from ALL competitive sports
Mitral Valve Prolapse • Two flapped valve between LA and LV balloons back into the LA with each HB.
YOU NEED A CARDIAC EVALUATION! When do you need to refer a patient
Referrals/Common Cardiac S/S • Syncope • Chest pain • Decreased exercise tolerance • Tachycardia or palpitations c exercise • New or loud murmur • Hypertension • Finding of Marfan syndrome • Family Hx
Referrals/Common Cardiac S/S • Dyspnea • Fatigue • Claudication • Skin Color, Temp and Aprearance • Generalized Edema
Cardiac Examination • Inspection: • Palpation: • Blood Pressure: • Pulse: • Auscultations:
Auscultations • A: (UR) • P: (UL) • T: (LL) • M: (Apex)
Diagnostic Testing • EKG • CXR • ECHO • Stress ECHO • Transesophageal ECHO • Thallium Scan • Cardiac Catheter
You need a cardiac Work-Up if: • Pathological Murmur during Diastole • If S1 or S2 not heard clearly • Murmur in UL or UR (pulmonary/aortic) • Any murmur > II • Scale: I= only cardiologist will hear II= Softest of Softest III= Soft IV= Stethoscope flat V= Stethoscope tilted VI= Stethoscope nearly touching
Commotio Cordis • Blunt chest trauma resulting in severe cardiac contusion • Immediate LOC, hypotension, rhythm disturbance • Tx: Precordial chest thump • AED & Early CPR
Summary • Sudden Death is a rare event • Work-up depends on (+) Hx, as PE is subtle or often normal • The first presentation of sudden death may be the event itself
