The duration of beta-blocker therapy in the treatment of ACS is a question mark among cardiologists and other health professionals, since, despite its widespread use, it is not known whether it produces the same results in the long term.
In fact, many studies involving these substances in heart disease are being made available more frequently, in order to understand whether this method of treatment is still the best for certain cases of heart attack and when it should be indicated.
As many professionals believe, the results are interesting. It was discovered that in cases of acute myocardial infarction with ST elevation, the use of beta-blockers does not reduce the level of mortality, and before that, this drug was widely used.
So what was once a certainty for many experts is now subject to further testing, as is the duration of use of these drugs.
Find out in this article when beta-blockers are indicated for ACS and why!
The use of beta-blockers in ACS is proven, but what about the long term?
There is no doubt about the efficacy of the use of beta-blockers in patients with acute coronary syndrome (ACS), and this is due to the data related to mortality and survival after this problem.
However, the scientific and medical community are unsure how long to administer this medication continuously after the syndrome.
And it's not for nothing. Recent research has provided interesting data that is worth analyzing.
The CAPITAL-RCT study does not recommend long-term use
Data from the CAPITAL-RCT study indicate that, in the long term, the use of beta-blockers added to standard therapy, especially in cases where there is no heart failure, may lose effectiveness over time.
In fact, another survey of 29,000 people in South Korea complements this theory.
The patients who underwent this study received beta-blockers for a period and were treated with revascularization therapy after ACS.
The study compared those who had taken it for less than a year (6,263) with those who had used it for a year or more (22,707).
The results indicated that patients who had been medicated for a year or more had a reduced risk of death from heart attacks and HF, just as in the 2 years, but those who had been using the drug for more than 3 years did not.
The study clearly shows that using the drug for more than a year continuously shows significant results, while after 36 months of continuous treatment, people start to show a higher mortality rate.
Time of beta-blocker therapy in the treatment of ACS: is there an ideal?
Even after these studies on the duration of beta-blocker therapy in the treatment of ACS found that the drug should be used for an appropriate period of time, there is no specific rule or date when the drug will necessarily lose its efficacy.
It is of the utmost importance that all health professionals involved in the case of a patient who has suffered ACS evaluate them periodically.
The use of beta-blockers is still one of the main guidelines in the treatment of acute heart attacks, but we must pay attention to the patient's behavior and clinical condition over the years.
Therefore, constant reassessment is suggested, as well as taking new therapy measures, to prevent the remedy from not having the desired effects.
