Simple medication can save the lives of cardiac patients

Cardiovascular disease is by far the most common cause of death worldwide, and myocardial infarction is the most common acute event. For those who survive a myocardial infarction, the risk of a new heart attack is greatest in the first year after the initial event because the blood vessels are more sensitive, making it easier for blood clots to develop. Reducing the “bad” cholesterol in the blood stabilises changes in the vessels, decreasing the risk for new events. The current established routine treatment is to treat with high-potency statins, immediately after the infarction. However, the majority of patients do not reach their treatment goals using only this medication. They need an add-on treatment in order to get down to the recommended cholesterol levels.
“Today’s guidelines recommend stepwise addition of lipid-lowering treatment. But it’s often the case that this escalation takes too long, it’s ineffective and patients are lost to follow-up,” says Margrét Leósdóttir, Associate Professor at Lund University and senior cardiology consultant at Skåne University Hospital in Malmö, Sweden.
In the study in question, she examined the prognosis of patients if the add-on therapy ezetimibe is applied early – (within 12 weeks after myocardial infarction), late (between 13 weeks and 16 months) or not at all. Based on Swedish registry data from 36,000 patients who had a myocardial infarction between 2015 and 2022, Margrét Leósdóttir´s research group has used advanced statistical models to emulate a clinical trial. The results show that patients who received a combination treatment of statins and ezetimibe within 12 weeks after the infarction and were able to lower cholesterol to the target level early, had a better prognosis and less risk of new cardiovascular events and death than those who received the add-on treatment late or never. Based on the results, many new heart attacks, strokes and deaths could be prevented every year if the treatment strategy would be changed.
“Combination therapy is not applied up-front for two main reasons. General recommendations are not included in today’s guidelines and a precautionary principle is applied to avoid side effects and overmedication. However, there are positive effects from applying both medicines as soon after the infarction as possible. Not doing this entails an increased risk. In addition, the drug we have examined in the study causes few side effects and is readily available and inexpensive in many countries.”
Margrét Leósdóttir hopes that the research results will in time provide support for changes in the recommendations. A treatment algorithm has already been introduced at her hospital in Sweden to help doctors to prescribe appropriate lipid-lowering treatment for patients who have had a myocardial infarction. It has been noted that patients achieve their treatment goals earlier and two months after the infarction twice as many patients have reduced their bad cholesterol to the target level, compared with previously.
“Several other hospitals in Sweden have also adopted the algorithm and there are similar examples from other countries that have produced as good results. My hope is that even more will review their procedures, so that more patients will get the right treatment in time, and we can thereby prevent unnecessary suffering and save lives.”

Combination of drugs could prevent thousands of heart attacks
Patients who receive an add-on medication soon after a heart attack have a significantly better prognosis than those who receive it later, or not all.
This is according to a new study from researchers at Lund University in Sweden and Imperial College London. ...

New tool for cutting DNA: promising prospects for biotechnology
An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA
A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands of nucleotides in deoxyribonucleic acid (DNA) to be cut. This makes it possible to specifically modify a targeted gene in plant, animal and human cells. Ultimately, CRISPR became a preferred method in the search for treatments for acquired or hereditary diseases.
Recently, ...

Victoria, BC— For the first time, footprints of armoured dinosaurs with tail clubs have been identified, following discoveries made in the Canadian Rockies. The 100-million-year-old fossilized footprints were found at sites at both Tumbler Ridge, BC, and northwestern Alberta.
There are two main groups of ankylosaurs. Nodosaurid ankylosaurs have a flexible tail and four toes, while ankylosaurid ankylosaurs have a sledgehammer-like tail club, and only three toes on their feet.
Unlike the well-known ankylosaur footprints called Tetrapodosaurus ...

COLUMBUS, Ohio – Insomnia and hazardous drinking are so closely intertwined that estimates suggest at least one-third, and as many as 91%, of people who have a hard time with sleep also misuse alcohol.
A new study suggests that perceived stress and depression factor into the relationship between the two conditions – perhaps not a surprise. But because the relationship between insomnia and heavy drinking goes in both directions, the influence of stress or depression depends on which condition came first, the analysis found.
“We were most interested in how insomnia leads to drinking, and we found that seems to occur primarily through ...

Years of research in the field of genetics have offered interesting insights spanning the origins and development of heredity and traits, offering valuable information on its influence on every aspect of life, right from eye color to susceptibility to certain diseases. But how do our genes influence the way we act, react to threats, and interact with others? Despite the recent advances in genetics, understanding the genetic foundations of behavior remains one of biology’s most fascinating challenges. Scientists have long turned to simpler organisms to help answer these questions, with the humble fruit fly emerging as an ideal candidate. These tiny insects share ...

DARIEN, IL — The American Academy of Sleep Medicine has released a new position statement emphasizing the clinical significance of sleepiness and its impact on performance, health, mood, safety, and quality of life.
The position states that sleepiness is a critical patient-reported outcome that is associated with an increased risk for adverse health effects and diminished quality of life. The statement urges health care professionals, policymakers, and researchers to prioritize the evaluation, management, and treatment of sleepiness ...

A new USC study suggests that gut imbalances in children with autism may create an imbalance of metabolites in the digestive system — ultimately disrupting neurotransmitter production and influencing behavioral symptoms.
The research, published today in Nature Communications, adds to a growing body of science implicating the “gut-brain” axis in autism. The discovery raises the possibility of new treatment avenues. It’s an example of how research at USC, and other universities, drives ...

A new study has shed unprecedented light on the highly variable and climate-sensitive routes that substances from Siberian rivers use to travel across the Arctic Ocean. The findings raise fresh concerns about the increasing spread of pollutants and the potential consequences for fragile polar ecosystems as climate change accelerates.
The international research, published today in Nature Communications and led by the University of Bristol, in the UK, provides the clearest ever picture of how the underlying transport system, known as the Transpolar Draft, operates. It also uncovers the various factors controlling this major Arctic surface current, ...
