1. See IVUS and atheroma for a better understanding of this issue. 2. Certain stimuli that cause atheroma may lead to enhanced sensitivity of vasculature. 3. Studies have also found that statins reduce atheroma progression. 4. In stable angina, the developing atheroma is protected with a fibrous cap. 5. Angiography only reveals the edge of the atheroma that protrudes into the lumen. 6. Increased concentrations of HDL correlate with lower rates of atheroma progressions and even regression. 7. However, atheromas within the vessel wall are soft and fragile with little elasticity. 8. OCT has the capability of visualize coronary plaque erosion and fibrotic caps overlying atheromas . 9. Large areas are called atheromas or plaque. 10. If atheroma , or clots, are protruding into the lumen, producing stenotic areas.
