Study Notes
Ischemic Heart Disease (IHD)
- IHD is a condition where the heart's blood supply is reduced, leading to reduced oxygen and impaired function
- Chronic coronary syndrome (stable angina) and acute coronary syndrome (unstable angina, NSTEMI, STEMI) are subtypes
- Atherosclerosis, plaque rupture, and thrombosis are key mechanisms causing IHD
- Risk factors include hypertension, diabetes, smoking, dyslipidemia, and genetic factors
- Clinical presentations vary depending on the type and severity of IHD
- Differentiating stable angina, unstable angina, and myocardial infarction (MI) is crucial for timely management
- Atypical presentations, especially in women and diabetics, require careful consideration
- Diagnosis employs ECG, cardiac biomarkers, stress testing, and imaging (like angiography)
- Essential pharmacological management includes antiplatelets, statins, beta-blockers, and nitrates
- Invasive procedures like PCI (percutaneous coronary intervention) and CABG (coronary artery bypass grafting) are used for severe cases
- Lifestyle modifications and secondary prevention are vital for long-term management
- Long-term consequences include potential heart failure, arrhythmias, and recurrent ischemia
Pathophysiology of IHD
- Atherosclerosis involves the buildup of plaque in the coronary arteries
- Plaque rupture leads to the exposure of underlying tissues and promotes clot formation (thrombosis)
- Ischemia results from the demand-supply mismatch, inflammation, and endothelial dysfunction in the heart
Clinical Features of IHD
- Stable angina presents with predictable chest pain that typically follows exertion and is relieved by rest
- Unstable angina features new onset or worsening angina, and even at rest
- NSTEMI (Non-ST-elevation myocardial infarction) and STEMI (ST-elevation myocardial infarction) exhibit distinct clinical presentations and ECG findings
- Atypical presentations require specific considerations for women, the elderly, or diabetic patients
Diagnostic Workup
- Recognizing IHD involves a thorough history and physical examination
- ECG reveals characteristic changes like ST-segment elevation or depression, and T-wave inversion
- Cardiac biomarkers (troponins and CK-MB) indicate myocardial damage
- Stress testing evaluates the heart's response to increased demand for blood flow
- Advanced imaging techniques including coronary CT angiography, stress echocardiography, and MRI provide detailed views of the coronary arteries
Management Strategies
- Management of stable angina initially involves lifestyle changes and pharmacological therapies
- Anti-anginals, antiplatelets, and statins are used to manage stable angina symptoms
- Emergency management of acute coronary syndromes (e.g., unstable angina, NSTEMI, STEMI) employs the MONA-B approach (Morphine, Oxygen, Nitrates, Aspirin, Beta-blockers)
- Reperfusion therapies like PCI or thrombolysis are used to restore blood flow to the heart
- Post-ACS (acute coronary syndrome) care emphasizes secondary prevention to reduce the risk of recurring events
Prognosis and Complications
- Long-term outcomes and potential complications associated with IHD include heart failure, arrhythmias, mechanical complications, and recurrent ischemia
- Factors contributing to the prognosis include severity, risk factors, and timely interventions
