Study Notes
Coronary Artery Disease Process
- Oxidized LDL attracts monocytes and macrophages to the site.
- Plaque formation occurs as cells embed into the endothelium.
- Lipids are engulfed by cells, forming foam cells, and smooth muscle cells develop.
- Coronary atherosclerosis occurs.
- Decreased coronary tissue perfusion follows
- Coronary ischemia is a result
- Decreased myocardial oxygenation occurs
- Angina pectoris and myocardial infarction may result.
Self-Management for Coronary Artery Disease
- Manage hypertension by taking prescribed medications regularly.
- Stop smoking immediately to improve oxygen supply to the heart.
- Avoid passive smoke exposure which reduces oxygen to the heart, and increases heart rate and blood pressure.
- Exercise regularly under medical supervision.
- Lose weight if overweight
- Follow a heart-healthy diet, reducing cholesterol and increasing fiber intake.
