Assessment of neutrophil extracellular traps in coronary thrombus of case series of patients with COVID-19

WellnessLeave a comment

What The Study Did: Severe COVID-19 is characterized by the intense formation of neutrophil extracellular traps (NETs), leading to the blockage of microvessels, as shown in pulmonary samples. The occurrence of ST-elevated myocardial infarction (STEMI) is a serious cardiac manifestation of COVID-19; the intrinsic mechanism of coronary thrombosis appears to still be unknown. This case series…
