Calcium Channel Blockers for Heart Failure
Why It Is Used
Calcium channel blockers may be used to treat Reference diastolic heart failure. Diastolic heart failure happens when your heart has a hard time filling with blood.
Calcium channel blockers may help your heart fill with blood more easily by slowing your heart rate and lowering your blood pressure. When your heart beats more slowly, it has more time to fill between each heartbeat. Calcium channel blockers may also help your heart muscle to relax, which can help your heart fill with blood. Lower blood pressure may help treat diastolic heart failure because your heart does not have to work as hard to pump blood.
Calcium channel blockers usually are not used for systolic heart failure, in which the heart has a hard time pumping out blood.
