Study Notes
Chronic Coronary Disease (CCD)
- Chronic coronary disease (CCD) is a type of coronary artery disease (CAD)
- CAD is a subset of cardiovascular disease (CVD)
Angina Definition and Types
- Angina is a result of imbalance between myocardial oxygen supply and demand
- Types of angina:
- Normal stable angina
- Unstable angina
- Variant angina
Epidemiology of CVD and CAD
- Cardiovascular disease (CVD) affects 49% of the population
- Coronary artery disease (CAD) affects 7.2% of the population
- Men are more affected by CAD than women
Angina Etiology and Pathophysiology
- Atherosclerosis leads to the formation of blood clots, which can cause angina
- Coronary spasm can also cause angina
- Angina occurs when there is an imbalance between myocardial oxygen supply and demand
