Improving Survival Following a Heart Attack
A
heart attack (also known as a
myocardial infarction) is a life-threatening event in which the supply of blood and oxygen to part of the heart is blocked for a long enough time that a portion of the heart muscle dies.
When people are given
metoprolol tartrate after a heart attack, the risk of dying decreases by up to 36 percent. It is not known how
metoprolol tartrate or other
beta blockers work to improve survival following a heart attack.
Is Metoprolol Tartrate Used for Children?
Metoprolol tartrate has not been approved for use in children, but it may be used
off-label to treat several conditions seen in children. For example, the medication may be used in children with
Marfan syndrome to slow down the progression of aortic dilation (widening of the aorta).
Off-Label Uses for Metoprolol Tartrate
On occasion, your healthcare provider may recommend metoprolol tartrate for treating something other than the conditions listed in this article. This is called an "off-label" use. Some off-label metoprolol tartrate uses include:
- Treatment of arrhythmias (abnormal electrical activity in the heart)
- Treatment of hyperthyroidism
- Migraine prevention
- Relief of alcohol withdrawal symptoms
- Treatment of anxiety, including social phobia and performance anxiety.
