Predictable chest pain with exertion or stress, relieved by rest or nitroglycerin.<\/li><li><strong>Unstable Angina<\/strong>: Part of acute coronary syndrome, chest pain occurs at rest or with minimal exertion, not relieved by nitroglycerin.<\/li><li><strong>Variant (Prinzmetal&#8217;s) Angina<\/strong>: Due to coronary artery spasm, occurs at rest, and is often cyclic.<\/li><\/ul>\n\n\n\n<h2>Pathophysiology:<\/h2>\n\n\n\n<ul><li><strong>Imbalance between myocardial oxygen supply and demand<\/strong>.<\/li><li><strong>Stable Angina<\/strong>: Due to atherosclerotic plaques limiting blood flow during increased demand.<\/li><li><strong>Unstable Angina<\/strong>: Often due to plaque rupture and partial thrombosis.<\/li><li><strong>Variant Angina<\/strong>: Spasm of the coronary arteries, not always associated with atherosclerosis.<\/li><\/ul>\n\n\n\n<h2>Risk Factors:<\/h2>\n\n\n\n<ul><li><strong>CAD risk factors<\/strong>: Age, smoking, hypertension, hyperlipidemia, diabetes, family history.<\/li><li><strong>Spasm triggers (for Variant Angina)<\/strong>: Smoking, cocaine use, cold weather.<\/li><\/ul>\n\n\n\n<h2>Clinical Features:<\/h2>\n\n\n\n<ul><li><strong>Chest pain<\/strong>: Described as pressure, tightness, or squeezing, typically retrosternal.<\/li><li><strong>Radiation<\/strong>: To the neck, jaw, shoulder, or arm.<\/li><li><strong>Associated symptoms<\/strong>: Dyspnea, nausea, diaphoresis.<\/li><li><strong>Relief<\/strong>: Rest and nitroglycerin help in stable angina.<\/li><\/ul>\n\n\n\n<h2>Diagnosis:<\/h2>\n\n\n\n<ul><li><strong>Clinical presentation<\/strong>.<\/li><li><strong>ECG<\/strong>: ST depression and T-wave inversion in stable angina during pain.<\/li><li><strong>Stress Testing<\/strong>: To provoke symptoms and detect ECG changes.<\/li><li><strong>Coronary Angiography<\/strong>: Gold standard to visualize coronary anatomy.<\/li><\/ul>\n\n\n\n<h2>Management:<\/h2>\n\n\n\n<ul><li><strong>Lifestyle modification<\/strong>: Smoking cessation, diet, exercise.<\/li><li><strong>Pharmacotherapy<\/strong>:<ul><li><strong>Nitroglycerin<\/strong>: For acute attacks.<\/li><li><strong>Beta-Blockers<\/strong>: First-line for chronic management.<\/li><li><strong>Calcium Channel Blockers<\/strong>: If beta-blockers are contraindicated or ineffective.<\/li><li><strong>Antiplatelet agents<\/strong>: Aspirin, clopidogrel.<\/li><li><strong>Statins<\/strong>: To control hyperlipidemia.<\/li><\/ul><\/li><li><strong>Revascularization<\/strong>: PCI or CABG for significant CAD or refractory
