As a cardiologist, I often meet patients who’ve stopped taking medicines that may keep them alive. Often the rationale is that they’ve seen a dramatic headline or disturbing TV report on a drug that they trust. But sometimes, patients have the best to listen: recent studies can really eliminate many years of medical exercises.
Very few medicines make this tension higher than beta blockers. After a heart attack, long-term suggestions, these medicines can save lives for some people, helpful and useless to others and even harmful.
Beta blockers have been used for greater than 40 years in all patients for heart attack. But this exercise was based on studies made before modern treatment, and before we detect a small heart attack that doesn’t affect the general work of the guts.
Recently, Couple Studies Beta blockers have been reported in heart attack patients. Spanish-Italian studies received probably the most attention. Media reports say that almost all heart attack patients didn’t profit from beta blockers, and on this Female This drug may also increase the danger of being hospitalized and Death.
Such reports will stop people taking their medicines.
In the identical Symposium In Madrid, the second study – which received less attention – the other appeared. Beta blockers benefited heart attack patients. And if there have been differences between sexes, women can really profit greater than men.
Heart of the matter: Edition Frection
The key to understanding different results is something called the left ventricular education fraction. It is a percentage of blood within the left chamber of the guts – its fundamental pumping chamber – which is pushed into the body with every heartbeat. Generally, the Education Fracture ought to be a minimum of 50 %.
If we take a look at all studies together together, including One I led and presented Last yr, the image becomes clear. Patients with a heart attack don’t profit from beta blockers after a heart attack. But patients with lower than 50 % of the Education Fracture profit. And that is true for each men and girls.
European Leaderships From 2023, the identical recently appeared US LeadershipsRecommend Beta blockers after a lot of the heart attack. Therefore, many doctors are reluctant to alter the tradition of therapy, which has been there for 40 years.

Me and my colleagues at the moment are planning to provide data from recent major studies about heart attack patients and a recent major study concerning the age of fifty or more. The expected results later this yr will probably give certain answers to beta blockers on this population and alter future guidelines.
But many patients explicitly profit from beta blockers, including heart failure and low ejection friction (with or with out a heart attack before), angina packetorous (chest pain on account of heartburn to blood flow), or different heart rhythm.
Beta blockers may also be advisable for other reasons, resembling hypertension, migraine prevention, together with earthquakes Off -label Use for stress and anxiety. For patients, it shouldn’t be easy to know all the explanations advisable by beta blockers, and in some cases, they will not be appropriate in any respect. So I’ll finish with a very good, good, if not a really novel, a chunk of recommendation: Always seek the advice of your doctor before making any changes to your medicine.
