Q

Unstable angina

A

Ischaemia caused by dynamic obstruction Unstable angina of a coronary artery due to plaque rupture or erosion with superimposed thrombosis

  • Angina (1) that occurs at rest or with minimal exertion, usually lasts more than
    10 min
    , (2) is severe and new of onset, and/or (3) that occurs with a crescendo pattern – more severe, prolonged, or frequent than previously

Q

Prinzmetal’s variant angina

A

**Focal spasm ** of an epicardial coronary artery leading to severe myocardial
ischemia. It occurs at rest, and associated with transient ST-segment elevation.

  • suspected in young female patient in 30s , transient ST elevation. Manage with ✅ CCB, and ❌never give Beta blockers يزود الضيق.

Typical angina pectoris:
A typical angina pectoris:
Pseudoangina:

A

1) retrosternal, chest pain
2) occurs after exertion or emotional⬆️
3) relieved by rest and nitroglycerin⬇️
____________________

only two from three characteristics (especially inwomen and diabetics, angina may be atypical in location and not strictly related to provocing factors)

———————————-

Q

Management of stable angina:

A

Pharmacology
- Antiplatelet:
Aspirin

  • Anti- angina:
    Nitrates
    Beta- blockers (cardio-selective “metoprolol, bisoprolol, carvedilol)
  • Lipid lowering agent:
    Statins

CCBs if Nitrates and B-blockers not effective”

surgery
- revascularisation therapy ( coronary angioplasty & coronary artery bypass, grafting “ CABG” )
