Final answer:
True, the Cardiovascular subsection contains codes for reporting diagnostic and therapeutic services for cardiovascular conditions. Atherosclerosis can lead to coronary artery disease and stroke by causing blockages.
Step-by-step explanation:
True or False: The Cardiovascular subsection of the Medicine section includes codes used to report diagnostic and therapeutic services. The answer is true. This subsection contains codes for reporting a wide range of services provided to diagnose and treat cardiovascular conditions. With regard to the content provided, there are several facts about the cardiovascular system and related diseases that are addressed.
Two cardiovascular diseases that can be caused by atherosclerosis are coronary artery disease (CAD) and stroke. Atherosclerosis contributes to CAD by the accumulation of plaque in the coronary arteries which can restrict blood flow to the heart muscle, leading to chest pain (angina) or a heart attack. A stroke can occur when these plaques rupture and cause a blood clot that blocks blood flow to a part of the brain.
Additionally, a heart attack is not the same as cardiac arrest. A heart attack occurs when blood flow to a part of the heart is blocked, while cardiac arrest is when the heart suddenly stops beating altogether.
The coronary arteries indeed carry blood to the heart muscle, supplying it with the oxygen and nutrients needed for its function. During systole, the heart contracts to pump blood out, and during diastole, the heart relaxes after contraction. The blood from the cardiac veins empties into the right atrium of the heart because it's part of the process that ensures deoxygenated blood is sent to the lungs for oxygenation.
