2. INTRODUCTION
• It is defined as the chest
pain towards left arm
shoulder due to less
supply of O2more
demand of O2 .
• Due to imbalance
between myocardium O2
requirement and O2
supply .
• TYPES :-stable, unstable,
variant .

3. Stable angina :
• Typical, classic, common angina.
• Occurs during emotional stress, heavy exercise
• Treating more by rest
• Easily predictable
• Due to atherosclerosis
• Depression of ST-segment in ECG.

4. Variant angina :
• Prize metal angina
• Occurs in rest also
• Due to spasm of coronary artery
• Treatment : vasodilators like nitroglycerin
• ECG show ST-segment elevation due to transmural
ischaemia .

5. Unstable angina
• Uncommon atypical type
• Occurs in exercise and also during rest.
• Prolonged angina may lead to myocardial infarction
• Unpredictable
• Non ST-segment elevation MI .

6. ETIOLOGY
• Coronary artery disease (CAD) : most common cause
rather than coronary artery spasm that may be due to :-
• Diabetes
• Elevated cholesterol
• High BP
• Smoking
•

7. Classification of anti-anginal drugs
• Nitrates (nitroglycerin)
• Calcium channel blockers (amlodipine)
• Beta-blockers
• Vasodilators
• Miscellaneous

9. Drug therapy
• Nitrates : improves blood flow by relaxing and dilating
veins and arteries .
• side effect : headache, increase HR
• Beta-blockers : decrease HR ,BP, and force of contraction
and amount of O2 heart required to pump blood .
• side effect : brandycardia, hallucination .
• Combination therapy :
• Nitrates + beta-blockers -stable angina
• Nitrates + calcium blockers unstable angina

10. Diagnosis :
• Electrocardiogram
• Stress test
• Chest X-ray
• Blood tests
• Coronary angiography

11. SYMPTOMS

12. Management :
• NON-PHARMACEUTICAL APPROACH :
• Quit smoking
• Controlling weight
• PHARMACOLOGICAL APPROACH :
• Nitrates
• Beta-blockers
• Calcium-channel blockers
• SURGICAL APPROACH :
• Angioplasty
• Coronary artery bypass surgery .
