Q

Medical management of heart failure and effects of medications

A

Loop diuretics: increase sodium and water excretion in the ascending loop of henle.
ACE inhibitors usually started first, then add a beta blocker.
If intolerant to ACE, can give Angiotensin II blockers instead.
Add an aldosterone antagonist (e.g. spironolactone if needed).

Q

What investigations to perform in atrial fibrillation

A

ECG, cardiac enzymes (exclude MI), Sats to check for shock. If patient is going to have cardio version (synchronised on R wave), a transesophageal echo is required to check for any thrombus which may be dislodged during procedure

47
Q

Causes of pericarditis

A

Common in patients with transmural MI, neoplasms, male sex. Dressler’s syndrome is common 2-6 weeks following an MI, autoimmune mediated

48
Q

Signs and symptoms of pericarditis

A

Retrosternal chest pain worst on lying down and inspiration, pericardial friction rub can be heard, fever.

49
Q

Explain ventricular free wall rupture

A

Occurs 1-2 weeks after MI. Patients present with acute heart failure due to cardiac tamponade (raised JVP, pulses paradoxus, diminished heart sounds). Urgent pericardiocentesis and thoracotomy

50
Q

Explain ventricular septal defect in MI

A

Rupture of the interventricular septum, occurs 1-2 weeks after an MI. Patient will present with acute heart failure with a pan systolic murmur. Surgery and echo are warranted.

51
Q

Common complication of infero- posterior infarction

A

Acute mitral regurgitation - due to ischaemia and rupture of papillary muscles.
