Cardiomypathy Flashcards
Symptoms of cardiomyopathies
Dilated: fatigue, dyspniae, pulmonary oedema symptoms, RVF symptoms, Emboli, AF, VT
Hypertrophic-Sudden death can be first sign of HCM, angina, dyspnoa, palpitation, syncope, CCF,
Restrictive-like constrictive pericarditis -These are mainly of right heart failure with raised JVP (, peripheral effusion, orthopnea, hypertension, bloating, ascites, hepatosplenomegaly)
Signs of cardiomyopathy
Dilated-pulse high, JVP high, Low BP, displaced apex, s3 gallop, mitrial/tricuspid regurg, pleural effusion, jaundice, hepatomegaly, ascites
Hypertrophic-sudden death. Jerky pulse. double apex beat, systolic thrill at left sternal edge, ejection systolic murmur
Restrictive-raised JVP, hepatomegaly, oedema, ascites, quiet heart sounds, S3,
test for cardiomypathy
Dilated-Bloods-BNP high (low Na is worse prognosis for CCF)
CXR-cardiomegaly, pulm oedema
ECG-tachycardia, poor R wave progression
Echo-dilated hypokinetic heart
Hypertrophic-ECG-LVH, progressie T wave inversion, deep q waves,
AF, WPW, WT
Echo-asymetrical septal hypertrophy, small LV, MITRIAL REGURG
Restrictive-diagnose with cardiac catheterisation
CXR-small heart
Management and features of HOCM
Leading cause of sudden cardiac death in young athletes
Usually due to a mutation in the gene encoding β-myosin heavy chain protein
Common cause of sudden death
Echo findings include MR, systolic anterior motion (SAM) of the anterior mitral valve and asymmetric septal hypertrophy
Management of dilated cardiomyopathy
idiopathic: the most common cause, then genetic, alcohol
duchennes
general-(mixed genetic/other)
dilated heart leading to predominately systolic dysfunction- all 4 dilated tho
classic findings of heart failure
systolic murmur: stretching of the valves may result in mitral and tricuspid regurgitation
S3
ECHO to diagnose–
HF sx- furosemid, stand up etc
Management of Restictive cardiomyopathy
Mixed genetic
Classic causes include
amyloidosis
post-radiotherapy
Loeffler’s endocarditis
Takutsubo (everything)
Acquired cardiomyopathy
Stress’-induced cardiomyopathy e.g. patient just found out family member dies then develops chest pain and features of heart failure
Transient, apical ballooning of the myocardium
Treatment is supportive
