Q

4 causes of raised JVP

A

Pqrst

  • pericardial effusion/ tamponade ( cause Kussmaul’s sign- paradoxical increase JVP during inspiration); constrictive pericarditis
  • quantity: Fluid overload
  • right Heart failure
  • superior vena cava obstruction
  • tricuspid regurg (V waves), tricuspid stenosis;

Q

What does X descent on JVP waveform represent

A

First part after A wave: relaXation of atria

C = tricuspid closure

Second part after C wave: end of RV contraction. Creates space in pericardium so atria can expand. Thus passive atrial filling

Q

Name 5 types cardiomyopathy

A
  • Dilated (systolic heart failure: pump failure → decreased flow )
  • restrictive (diastolic hf: small chamber → decreased vol→ decreased flow)
  • hypertrophic / obstructive (diastolic: asymmetrical thickening of wall → blockage → reduced flow)

  • S4 (atria contract and push blood against non-compliant ventricular wall)
80

Primary (this is the most common type of 1° cardiomyopathy

  • autosomal dominant mutation in genes that code for sarcomere proteins

Secondary

  • chronic ht
  • aortic stenosis
  • Friedrich’s ataxia
  • Fabry’s disease
81
Q

Presentation hypertrophic cardiomyopathy? (3)

A
  • Asymptomatic or
  • heart failure symptoms or
  • sudden death!
82
Q

Name 2 types obstructive cardiomyopathy

A
  • Obstructive type: most common. Interventricular septal hypertrophy blocks aortic outflow. Characterised by tachy
  • non-obstructive type: left ventricular hypertrophy. Ejection fraction preserved in early stages
83
Q

Name 5 specific heart exam findings in hypertrophic cardiomyopathy

A
  • S4 gallop
  • late ejection systolic crescendo-decrescendo murmur at llsb + apex due to obstruction ( maneuvers give it away)
  • louder with valsalva (bc this decreases preload,), nitrates (decrease after load)
  • softer on hand grip (increases after load) / squat (increase preload)
  • diffuse apex
84
Q

Treatment obstructive (hypertrophic) cardiomyopathy? (3)

A

Treat pump failure

  • beta blocker ( slow heart rate → heart has more time to fill → increase outflow → decrease symptoms )
  • consider: septal reduction with alcohol injection/ surgery; heart transplant

Amiodarone for arrhythmia
Anticoagulant for paroxysmal Afib or systemic emboli

Nb: digoxin contraindicated (may increase inotropy [beat with force] → exacerbate symptoms and worsen disease)

85
Q

Treatment dilated cardiomyopathy (5)

A

Treat back up of blood:

  • low salt diet, bed rest
  • diuretics
  • ace - inhibitor (also decreases outflow resistance)

Treat pump failure

  • beta blockers / CCB (decrease oxygen demand of heart )
  • digoxin ( increase contractile strength to overcome pump failure )
  • consider: pacemaker, heart transplant

Anticoagulant

86
Q

Treatment restrictive cardiomyopathy? (3)
