A. Gradual onset chest pain
B. Absent peripheral pulses
C. Collapsing Pulse
D. Haemoptysis
E. Abdominal Pain

Q

Mr B a 52 year old male presents to his GP with central, tight chest pain. He has noticed the pain comes on when he is gardening or walking to the bus stop in a hurry, but normally goes away when he rests. What medication would the GP prescribe to treat his underlying condition?

A. GTN spray
B. Propanolol (Beta Blocker) 
C. Ramipril (ACEi)
D. Aspirin
E. Atorvastatin (Statin)

Q

How would you diagnose and clinically assess angina?

A

Diagnosis is based on features of anginal pain:

  • Constricting discomfort in the chest, or neck, shoulders, jaw, arms
  • Precipitated by exercise
  • Relieved by rest or GTN within 5 minutes

Clinical Assessment
3 features = typical angina
2 features = atypical angina
1 or no features = non-anginal pain

ST elevation on ECG (or new onset LBBB)

54
Q

A 
Ischaemic complications
Mechanical complications
Arrhythmic complications
Cardiac Arrest
Pericarditis
57
Q

What are the ischaemic complications of ACS?

A

  2. Post-infarction Angina – occurs from a few hours to 30 days post MI. More commonly seen in NSTEMIs
58
Q

What are the mechanical complications of ACS?

A
  1. Heart Failure – result of damaged cardiac tissue. Can range from mild signs of HF to cardiogenic shock
  2. Papilliary Muscle Rupture – Mitral Regurgitation post MI is found in between 15-30% of patients but is usually transient and asymptomatic.
    PMR is life-threatening – new and loud pan-systolic murmur at apex, radiating to the axilla.
  3. Ventricular Aneurysm – aneurysm arising from weakened ventricular wall which can block the outflow of blood from the heart
59
Q

A

VT, VF
Complete Heart Block
Reentry circuits

60
Q

What is the difference between an MI and Cardiac Arrest?

A

Cardiac Arrest = electrical problem
MI = circulatory problem – damaged heart muscle can result in cardiac arrest
MI can cause a CA

61
Q

How quickly after an MI does pericarditis develop?

A

Early - 24-96 hours post MI –> inflammatory response to necrotic tissue
Dressler’s Syndrome – 2-12 weeks post MI due to antibodies forming against circulating myocardial antigens

LMWH as an alternative if pts. undergoing angiography

72
Q

What is the GRACE Risk Score?

A

73
Q

What is the management of GRACE high risk patients?

A

IV Glycoprotein IIb/IIIa inhibitors - Tirofiban/Eptifibatide

Coronary angiography (+ follow on PCI if indicated) within 96 hours of admission
