Calcium-channel blocking drugs are effective in:Group of answer choicesdecreasing all types of cardiac arrhythmiasreducing cardiac and smooth muscle contractions.reducing the risk of blood clotting.decreasing the attraction of cholesterol into lipid plaques.
Solution
Calcium-channel blocking drugs are effective in reducing cardiac and smooth muscle contractions.
Here's why:
-
Calcium-channel blockers work by blocking calcium from entering cells of the heart and blood vessel walls. This results in less forceful heart contractions and dilates the arteries, reducing the amount of pressure on the arterial walls.
-
This reduction in heart contractions and dilation of the arteries can help to reduce the symptoms of conditions such as high blood pressure, angina, and some types of arrhythmia.
-
However, they do not directly reduce all types of cardiac arrhythmias, decrease the attraction of cholesterol into lipid plaques, or reduce the risk of blood clotting. These are effects of other types of cardiovascular drugs.
-
Therefore, the most accurate statement is that calcium-channel blocking drugs are effective in reducing cardiac and smooth muscle contractions.
