Types Of Angina

Discuss The Types Of Angina And Common Drugs Used In Each Type Of Angina.
Answer:

Types of angina

Classical Angina Or Stable Angina

Attacks (chest pain) are predictably provoked by exercise, anxiety, eating, or coitus and subside when the increased energy demand is withdrawn.
Drugs that are useful, primarily reduce cardiac work. They may also cause a favorable redistribution of blood flow to the ischemic areas.

Types of Angina: Stable, Unstable, and Variant Angina

Angina Drugs Used

• Nitroglycerine is the choice of drug.
• For an acute attack, nitroglycerine is given sublingually with an initial dose of 0.5 mg which relieves pain in 2 to 3 min.
• For prophylaxis, isosorbide mononitrate orally is given.

Variant/Prinzmetal`s/Vasospastic Angina

Attacks occur at rest or during sleep and are unpredictable. They are due to recurrent localized (occasionally diffuse) coronary vasospasm which may be superimposed on arteriosclerotic coronary artery disease. Drugs are aimed at preventing and relieving coronary vasospasm.

Angina Types: Causes, Symptoms, and Treatment

Angina Drugs Used

• Episodes of coronary vasospasm should be treated with nitrates
• For prophylaxis nitrates and calcium channel blockers are effective.
• The association of calcium channel blockers with nitrate produces good efficacy in variant angina.

Angina Unstable Angina

The rapid increase in duration and severity of attacks is mostly due to the rupture of an atheromatous plaque attracting platelet deposition and incomplete occlusion of the coronary artery; occasionally with associated coronary vasospasm.

Stable Angina vs Unstable Angina: Differences and Treatment

Angina Drugs Used

It needs treatment with multiple drugs:

• Antiplatelet agents: Low-dose aspirin, clopidogrel, etc are used
• Anticoagulants: Low molecular weight heparin or unfractionated heparin is used.
• Nitrates: Nitroglycerin sublingually is effective.
• Beta-blockers: Atenolol or metoprolol are routinely administered in unstable angina.
• Calcium channel blockers: Amlodipine, nifedipine, diltiazem, or verapamil are used if symptoms persist in patients with nitrates
• Statins: They improve outcomes in unstable angina.
