It has become easier to treat this disease for both surgeons and patients.
A team of scientists from Sechenov University together with specialists from the Moscow Regional Scientific and Clinical Institute named following M.F. Vladimirsky developed a technology for delayed stenting of arteries in myocardial infarction, the head of the department for endovascular treatment of cardiovascular diseases and arrhythmias of the Moscow Regional Scientific and Clinical Institute named following M.F. Vladimirsky, Associate Professor of the Department of Interventional Cardioangiology of Sechenov University Alexei Azarov.
A patient with acute myocardial infarction needs to place a stent as soon as possible to expand the lumen of the vessel and restore blood flow. But sometimes the conditions for stent implantation are not optimal, for example, due to the large mass of the thrombus in the vessel.
This can lead to complications, including microvascular obstruction (a clot breaks down and clogs the smallest arteries).
“To minimize them, we use the method of two-stage revascularization (restoration of blood supply to a part of the body or organ that has undergone ischemia). First, with the help of medications, we create conditions for the thrombus in the artery of the heart to dissolve, and then we perform stenting of this segment. Now, with the use of new methods of intravascular imaging and angiographic complexes, we can examine the plaque from the inside, fully examine it, and compile a complete ultrasound picture,” the specialist explained.
According to Azarov, this allows to verify the cause of an acute infarction, to obtain an ultrasound picture of the entire plaque.
“The work is devoted to a two-stage method that allows you to cause resorption of thrombotic masses and only then install a stent. This is a technology for delayed stenting of the coronary arteries – a stent can be placed not in case of acute myocardial infarction, but already in a delayed situation, when we have the opportunity to more accurately select the diameter of the stent, its length, which directly affects the long-term prognosis. Thus, treating a heart attack has become even easier, both for the surgeon and for the patient,” the surgeon concluded.
Modern medicine does not stand still and is constantly evolving. Read in the gallery regarding the main medical discoveries of the XXI century:
Two of the three types of polio have been eradicated; the last one is coming. Following the type 2 poliovirus, officially declared eradicated in 2015, type 3 virus ceased to exist on October 24, 2019. The last case of infection was recorded in 2012 in Nigeria. All of this has been made possible by the widespread use of vaccines since the 1950s.

Artificial intelligence has learned to predict the structure of proteins. The ability to predict, simply from the sequence of amino acids, what the three-dimensional structure of any protein, of which there are hundreds of thousands in the human body, will not only revolutionize biology, it opens up new possibilities for drug development and the treatment of many diseases.

Malaria will be defeated. Malaria might be completely eradicated by 2050, according to The Lancet. As one of the decisive measures, it is proposed to change the DNA of mosquitoes, which will lead to their infertility or make them resistant to malarial plasmodia.

CRISPR/Cas9 is a genome editing technology that allows it to be adapted for treatment. Theoretically, it will make it possible to better study the course of various complex diseases and “reprogram” the diseased organism for recovery.

Creation of antibodies for viral diseases. Laboratory-created monoclonal antibodies have already revolutionized the treatment of autoimmune diseases and certain types of cancer, but so far their use for treating infections has been limited.

First coronavirus vaccines in record time. The way humanity reacted to the coronavirus pandemic, of course, cannot be called a standard – but thanks to the active work of the scientific community, it was possible to create effective vaccines very quickly.

Cancer has been identified through a blood test. In 2020, trials of a universal blood test started in the UK, which allows to detect up to 50 types of cancer at an early stage. The study will be completed in 2023, and if it shows its effectiveness, then by the middle of the decade, blood tests for cancer will become massive.

Hepatitis C has become completely curable. Literally over the past few years, the effectiveness of drugs from the “gentle killer” has approached 100%. Such progress came with the introduction of interferon-free treatment regimens.

Alzheimer’s disease will learn to predict. Alzheimer’s blood test is another small medical revolution of 2020. Scientists have learned to identify the relevant biomarkers in blood plasma regarding four years before the onset of the first symptoms of the disease, which means that such a blood test can be included in annual medical examination programs and recommendations for patients.
