Question
In coronary heart disease:The heart beats too slowlyThe heart valves do not work properlyThe heart beats too quicklyThe arteries that supply blood to the heart muscle become narrow
Solution
In coronary heart disease, the arteries that supply blood to the heart muscle become narrow. This is due to the buildup of plaque on the inner walls of the arteries, a process known as atherosclerosis. This can reduce blood flow to the heart muscle, causing chest pain (angina), shortness of breath, heart attack, and other symptoms.
The other options you mentioned - the heart beating too slowly, the heart valves not working properly, and the heart beating too quickly - are not specific to coronary heart disease. They can occur in various other heart conditions. For example, the heart beating too slowly is a condition called bradycardia, and the heart valves not working properly can refer to various valvular heart diseases. The heart beating too quickly can refer to tachycardia.
It's important to note that while these conditions can occur separately, they can also occur in combination with each other, and a person can have more than one heart condition at the same time.
