Final answer:
The progression of cardiovascular disease typically begins with coronary arteriosclerosis, which can lead to congestive heart failure as the heart's ability to pump blood is compromised. Following heart failure, pulmonary edema may occur due to fluid accumulation in the lungs.
Step-by-step explanation:
Order of Events: Coronary Arteriosclerosis, Congestive Heart Failure, Pulmonary Edema
Understanding the correct order of the events among coronary arteriosclerosis, congestive heart failure, and pulmonary edema starts with recognizing the progression of cardiovascular diseases. Coronary arteriosclerosis refers to the buildup of plaques in the coronary arteries which can lead to obstruction of blood flow, ischemia, and hypoxia. As plaques in the coronary arteries continue to grow, they can result in the complete blockage of these arteries, leading to myocardial infarction (heart attack) or angina.
Congestive heart failure (CHF) may then follow, as the heart struggles to pump blood efficiently through the body due to the damage sustained from the reduced blood flow. This inefficiency can cause blood to back up into the lungs or other parts of the body. Following CHF, pulmonary edema can occur, which is the accumulation of fluid in the lungs' air sacs, further complicating the ability of the lungs to exchange oxygen and carbon dioxide.
Therefore, the correct order of events would be:
- Coronary Arteriosclerosis
- Congestive Heart Failure
- Pulmonary Edema
Arteriosclerosis leads to decreased blood flow and potential heart damage, which can subsequently cause the heart to become less efficient (CHF), eventually leading to fluid accumulation in the lungs (pulmonary edema).
