Which of the following could lead to a heart attack from coronary artery disease? Oxygen rich blood goes to the ventricles Arteries to the heart muscle are blocked Bad valves can't regulate blood flow Low number of red blood cells

## Step 1<br />The question is asking us to identify the condition that could lead to a heart attack from coronary artery disease. <br /><br />## Step 2<br />Coronary artery disease is a condition where the arteries that supply oxygen-rich blood to the heart muscle become blocked or narrowed. This is usually due to the buildup of fatty material (atheroma) within the arteries.<br /><br />## Step 3<br />When the arteries are blocked, the blood flow to the heart muscle is restricted. This means that the heart muscle is not getting the oxygen it needs to function properly.<br /><br />## Step 4<br />If the blockage is severe enough, it can cause a heart attack. This is because the heart muscle is not getting the oxygen it needs, which can lead to cell death and tissue damage.
