Atherosclerosis -- sometimes called hardening of the arteries -- can slowly narrow and harden the arteries throughout the body. When atherosclerosis affects the arteries of the heart, it’s called coronary artery disease.
Coronary artery disease is the No. 1 killer of Americans. Most of these deaths are from heart attacks caused by sudden blood clots in the heart’s arteries.
Atherosclerosis can create life-threatening blockages without you ever feeling a thing. Since we’re all at risk for coronary...
Beta-blockers can be taken in the morning, at meals, and at bedtime; taking them with food minimize side effects because absorption is slower. Follow the label directions on how often to take a beta-blocker. The number of doses you take each day, the time allowed between doses, and how long you need to take the medication will depend on your condition. Ask your doctor what to do if you miss a dose.
Beta-blockers should not be prescribed if you have low blood pressure or a slow pulse, because the further reduction in heart rate can cause dizziness and lightheadedness. If you have asthma or COPD, your doctor may not prescribe a beta-blocker because it may worsen symptoms. If you have heart failure and severe lung congestion, your doctor will treat your congestion before prescribing a beta-blocker.
While you are taking a beta-blocker, you may need to record your pulse every day. If your pulse is slower than it should be, contact your doctor about taking your beta-blocker that day.
Never stop taking a beta-blocker without speaking to your doctor first, even if you feel that it is not working. Sudden withdrawal can worsen angina and cause heart attacks.
