Stable angina Flashcards
Stable angina
- Ischaemia due to fixed atheromatous Stable angina stenosis of one or more coronary arteries
- Angina which occurs predictably at a certain level of activity
Unstable angina
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
Myocardial infarction
Myocardial necrosis caused by acute Myocardial infarction
occlusion of a coronary artery due to plaque rupture or erosion with superimposed thrombosis
Most common of death in patient with CAD is?
Ventricular arrhythmia
Prinzmetal’s variant angina
**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.
Risk factors:
Most important ➡️ HTN 📍
Worst one ➡️DM 🆙 accelerate atherosclerosis
Most important in intervention ➡️ smoking 🚬
- Hyperlipidemia and Obesity.
- Family history of premature coronary artery
disease. in female less than 65 , in male less than 55.
-Age above 45 in men and above 55 in women. - Sedentary lifestyle.
- Sleep disorders, such as obstructive sleep apnea.
- Chronic kidney disease
most common cause of death in CKD patient is CAD
Typical angina pectoris:
A typical angina pectoris:
Pseudoangina:
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)
———————————-
Only one or no one out of three characteristics.
the most common cause of angina?
Angina equivalent?
Coronary atheroma
——- ——————
SOB , nausea, diaphoresis , fatigue , without chest pain the symptoms relieve with Nitroglycerin
Presentation:
Signs & symptoms….
Symptoms:
1) Retrosternal pain➡️ ( diffuse not localized , described as heaviness &pressure & squeezing , lasts typically 2-5 minutes , radiating either shoulder & to both arms , relieved by rest & nitroglycerin
2) Dyspnoe
3) Fatique , faintness
4) Nausea, vomiting
5) sweating
6) Sense of impending doom with MI
Signs
- 3rd & 4th heart sound
- Apical systolic murmur
- pulmonary congestion
Work up:stable angina
1) Resting ECG➡️ reversible ST depression with or without T- wave inversion
2) Exercise ECG
3) Myocardial perfusion scanning
4) Stress echocardiography
5) Coronary angiography➡️ definitive diagnostic test ✅
Management of stable angina:
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” )
