During the Christmas holidays, a freezer failure occurred in the Neo building on KI's Flemingsberg campus. The automatic filling of the cryotanks with liquid nitrogen was interrupted for an unknown reason. As a result, the temperature in 16 of 19 cryogenic tanks rose and large amounts of biological research material have been destroyed. An investigation with internal and external experts is now underway to find out how this failure could have happened.

Researchers at Karolinska Institutet have evaluated the possibility of alerting drones equipped with automated external defibrillators (AED) to patients with suspected cardiac arrest. In more than half of the cases, the drones were ahead of the ambulance by an average of three minutes. In cases where the patient was in cardiac arrest, the drone-delivered defibrillator was used in a majority of cases. The results have been published in the journal The Lancet Digital Health.

Online cognitive behavioral therapy (CBT) shows promising effects on quality of life, as well as reduced healthcare consumption for patients with paroxysmal (i.e., intermittent) symptomatic atrial fibrillation, according to a new study in the Journal of the American College of Cardiology. According to the researchers, this is the world's first randomized controlled trial of CBT for patients with atrial fibrillation (AF).

In the largest survey to date, researchers at Karolinska Institutet have studied how diseases of the aortic valve affect prognosis in patients with various types of heart failure. The study was published in the European Journal of Heart Failure. Shared first authors are sisters Angiza and Bahira Shahim, who also presented the results of the study at the Heart Failure International Conference in Prague.
News
Researchers at Karolinska Institutet have investigated how preterm birth and foetal growth are related to the risk of atrial fibrillation up to middle-age. The study, which is published in JAMA Pediatrics, shows that being born preterm or large for gestational age was associated with increased risks of atrial fibrillation later in life. Being small for gestational age at birth was only associated with an increased risk of atrial fibrillation up to the age of 18.

Losing too much weight when infected with COVID-19 has been linked to worse outcomes. Now, researchers at Karolinska Institutet have discovered that SARS-CoV-2 infection fuels blood vessel formation in fat tissues, thus revving up the body’s thermogenic metabolism. Blocking this process by using an existing drug curbed weight loss in mice and hamsters that were infected with the virus, according to the study published in the journal Nature Metabolism.
News
Volunteer so-called SMS lifesavers in Sweden, who are alerted to cardiac arrests nearby using a mobile app, perform a large part of life-saving efforts before the ambulance, police or emergency services arrive, regardless if they are instructed to collect the nearest defibrillator or not. This is according to a new study from Karolinska Institutet published in JAMA Cardiology.
News
Atrial fibrillation is the greatest risk factor for stroke. Screening to detect atrial fibrillation in older people would not only increase the chance of preventing stroke, it would also save money for the healthcare system and society, according to a study conducted at Linköping University and Karolinska Institutet, published in the European Heart Journal.
News
An observational study at Karolinska Institutet shows that babies suffering oxygen-deficiency complications at birth are almost twice as likely to develop cardiovascular disease during childhood and early adulthood as those without such complications. Still, the absolute risk of cardiovascular disease is very low in young age. The findings are published in the journal The Lancet Regional Health – Europe.
News
Adults with ADHD are at greater risk of developing a range of cardiovascular diseases than those without the condition, according to a large observational study led by researchers at Karolinska Institutet and Örebro University. The researchers say the findings, published in the journal World Psychiatry, underscore the need to monitor cardiovascular health in people with ADHD.
News
Professor Göran K. Hansson has been awarded the European Society of Cardiology's gold medal. He is honored for his research efforts and, above all, for his discoveries on the role of inflammation in cardiovascular disease. The gold medal is the society's premier award and is awarded for outstanding contributions to cardiovascular medicine and was awarded at the congress in Barcelona.
News
A study led by Karolinska Institutet shows that it often takes weeks for patients with heart failure to be prescribed the recommended treatments, especially relatively new drugs such as dapagliflozin and sacubitril/valsartan. According to the researchers, the results are troubling as these treatments reduce the risk of death and heart failure hospitalization, and improve the patients’ life quality. The study is published in the journal JACC: Heart Failure.
News
Researchers at Karolinska Institutet, Germany’s Technical University of Munich (TUM) and AstraZeneca, among others, have identified a unique therapeutic approach with the potential to restore heart function following a heart attack. The new findings rely on so-called human ventricular progenitor (HVP) cells to promote novel heart tissue and reduce scarring after injury. This pre-clinical study is published in the journal Nature Cell Biology.
News
Researchers at Karolinska Institutet have studied long-term morbidity and mortality in individuals who have had different models of biological heart valves implanted. The results, which show that there are considerable differences in performance depending on model group, are published in the journal JAMA Network Open.
News
Sweden is one of the few countries that have removed the dental health recommendation to give prophylactic antibiotics to people at a higher risk of infection of the heart valves, so-called infective endocarditis. Since the recommendation was removed in 2012, there has been no increase in this disease, a registry study from Karolinska Institutet published in the journal Clinical Infectious Diseases shows.
News
The risk of developing cardiovascular disease is strongly associated with the “bad” LDL cholesterol. A large study by scientists at Karolinska Institutet now shows that two proteins that transport cholesterol particles in the blood provide early and reliable risk information. The researchers advocate introducing new guidelines for detecting cardiac risk and say the results, published in PLOS Medicine, may pave the way for early treatment, which could help lower morbidity and fatality rates.
News
Socioeconomic factors affect the risk of cardiovascular disease and the chances of recovery. New research from Karolinska Institutet interrogates the significance of socioeconomic factors for sudden out-of-hospital cardiac arrest. The study, which is published in Circulation, shows that education and income impact survival rates in both men and women.

Some of these factors are already known, but using machine learning techniques, the researchers have found additional predictors, such as smoking, blood pressure and blood glucose.
News
In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging of the heart can greatly increase the rate of diagnosis. The study has been published in the journal JACC Cardiovascular Imaging.

Concerns have been raised that the use of a common group of medications called RAS inhibitors could facilitate SARS-CoV-2 infection, impact COVID-19 disease severity and worsen prognosis. However, in a new nationwide registry-based study from Karolinska Institutet, including almost 1.4 million patients, use of RAS inhibitors was not associated with increased risk of hospitalisation or death from COVID-19. The study has been published in the European Journal of Heart Failure.
