Study Notes
Types of Angina
- Angina is classified into three types: stable, unstable, and variant (Prinzmetal's).
- Stable angina occurs predictably with exertion, linked to stable plaque in coronary arteries.
- Unstable angina is a critical concern, often a precursor to acute coronary syndrome (ACS).
- Variant angina involves chest pain episodes at rest caused by coronary artery vasospasms.
Risk Factors for Angina
- Increased myocardial oxygen demand due to stress, exercise, cold exposure, and smoking.
- Smokers face a 2-4 times higher risk of coronary heart disease compared to non-smokers.
- Sudden cardiac death and ACS risk are heightened by cigarette smoking and exposure to secondhand smoke.
- Regular exercise can mitigate many risk factors associated with heart disease.
Treatment and Management
- Stable angina treatment focuses on lifestyle changes and managing risk factors.
- Variant angina often treated with calcium channel blockers and long-acting nitrates.
- Cardiac catheterization may reveal transient coronary spasms without significant plaque.
Obesity and Metabolic Syndrome
- Extreme obesity (BMI ≥ 40 kg/m²) significantly increases cardiovascular risk.
- Overweight is classified as a BMI of 25.9 to 29.9 kg/m².
- Metabolic syndrome includes hyperglycemia, hyperinsulinemia, central obesity, high triglycerides, LDL, and low HDL levels.
Impact of Stress and Alcohol
- High stress increases cardiovascular workload, elevates blood pressure (BP), and heart rate (HR).
- Stress management is crucial for reducing risk of coronary events.
- Excessive alcohol consumption contributes to elevated BP and triglyceride levels, impacting heart health.
Menopause and Cardiac Risk
- Early menopause (under 39) and late menopause (over 56) are linked to increased cardiovascular risk.
- Women’s CAD risk equalizes or surpasses men’s risk by age 75.
ECG Changes in Myocardial Infarction (MI)
- ST-segment elevation in certain leads identifies specific sites of myocardial infarction.
- Anterior wall MIs show elevations in V2-V4; lateral wall MIs in V5-V6; inferior wall MIs in II, III, aVF.
- Pathologic Q waves and ST-segment changes are critical indicators for diagnosing MIs.
Cardiac Biomarkers
- Elevated cardiac troponins indicate myocardial damage; levels above 0.1 ng/mL suggest a high risk of complications.
