Right Pulmonary Artery Cholesterol Embolism, or RPACE, is a medical condition that occurs when cholesterol particles travel to the right pulmonary artery, causing various complications. In this article, we will delve into the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options associated with RPACE in simple and accessible language.
Types of RPACE:
- Small Emboli:
- These involve tiny cholesterol particles that may not cause noticeable symptoms initially.
- Large Emboli:
- In contrast, larger particles can block blood vessels, leading to more severe symptoms and complications.
Common Causes of RPACE:
- Atherosclerosis:
- The buildup of cholesterol plaques in arteries.
- High Cholesterol:
- Elevated levels of cholesterol in the bloodstream.
- Cardiac Surgery:
- Surgical procedures on the heart can dislodge cholesterol particles.
- Atrial Fibrillation:
- An irregular heart rhythm contributing to clot formation.
- Hypertension:
- High blood pressure can damage artery walls.
- Obesity:
- Excess body weight can contribute to cholesterol-related issues.
- Diabetes:
- Poorly managed diabetes may increase the risk of cholesterol emboli.

- Tobacco use can damage blood vessels and promote clotting.
- Genetic Factors:
- Inherited conditions affecting cholesterol metabolism.
- Age:
- Older individuals may be more susceptible to cholesterol-related issues.
