[Acute myocardial infarction and cardiogenic shock in patient with COVID-19].

The conditions of the pandemic caused by the novel coronavirus infection (COVID-19) are associated with overloading intensive care units, conversion of hospitals, and changes in routing of patients with acute cardiovascular pathology. At the same time, medical practice is still challenged to provide medical care to patients with acute coronary syndrome (ACS). Patients with COVID-19 and acute myocardial infarction (AMI) are at a higher risk of death while the incidence of this combination of diseases will be growing.

[Early Invasive Strategy in Patients over 75 Years with Acute Coronary Syndrome. A Single Center Study].

Objective: to assess the clinical status, comorbidities, complications, in-hospital mortality and its structure in dependence of age and type of acute coronary syndrome (ACS) in case of early invasive strategy of ACS management.

Materials And Methods: we included in this retrospective study data of all patients (n=1353) with ACS subjected to emergency and urgent myocardial revascularization in High Medical Technologies Center (Kaliningrad, Russia) in 2014-2016. Age of 984 patients was <75 (group 1) and of 369 >75 years (group 2).

Practical Parametrization for Line Shapes of Near-Threshold States.

Numerous quarkonium(like) states lying near S-wave thresholds are observed experimentally. We propose a self-consistent approach to these near-threshold states compatible with unitarity and analyticity. The underlying coupled-channel system includes a bare pole and an arbitrary number of elastic and inelastic channels treated fully nonperturbatively.
