We present a case of 75-year-old male who underwent percutaneous coronary intervention in the setting acute myocardial infarction with ST-segment elevation and was hospitalized 12 days afterwards COVID-19 pneumonia. Later patient presented himself again syndrome same region due to in-stent thrombosis. Transient atrioventricular conduction disorders were registered before after intervention. Pos...

BACKGROUND Cotton wool spots are known to be a complication in patients with thrombotic thrombocytopenic purpura or with polymyositis. CASE A 53-year-old woman developed numerous cotton wool spots around the optic disc of both eyes. OBSERVATIONS Fluorescein angiography disclosed capillary obstruction and microaneurysms in the early phase, followed by dye leakage in the late phase. Systemica...

The cause of platelet agglutination in thrombotic thrombocytopenic purpura has been an enigma. Current evidence indicates that the interaction of platelets with a platelet-aggregating factor or unusually large multimers of factor Vlllrvon Willebrand factor, or both, may cause the abnormal platelet agglutination. Recent success in the treatment of thrombotic thrombocytopenic purpura with intrave...

In a prospective study of 90 consecutive patients with acute myocardial infarction, 15 (28.3%) of 53 patients with an anterior wall infarction developed a left ventricular thrombosis diagnosed by cross sectional echocardiography. Patients received anticoagulants only after a left ventricular thrombosis had been diagnosed. Twenty eight patients had an inferior infarction, but none of these had a...

Simultaneous thrombotic occlusion of multiple coronary arteries in acute myocardial infarction is a well-recognised phenomenon. Studies have reported diffuse destabilisation of atherosclerotic plaques in patients with acute myocardial infarction, leading to the concept of "pan-coronaritis". The putative mechanism is attributed to a systemic thrombophilic and inflammatory state. We report the oc...

T he role of thrombotic processes in the conversion of a quiescent atherosclerotic plaque into a clinically active atherothrombotic le-sion has been well established over the past decade.' In coronary, cerebral, and peripheral arterial beds, atherothrombotic events underlie acute clinical vas-cular syndromes ranging from unstable angina and myocardial infarction to transient ischemic attack and...

Thrombotic microangiopathies (TMAs) are a group of life-threatening disorders characterized by thrombocytopenia, fragmentation of erythrocytes, and ischemic organ damage. Genetic disorders, autoimmune disease, and cancer are risk factors for TMAs, but an additional, unknown trigger is needed to bring about acute disease. Recent studies suggest that DNA and histones are released during inflammat...

Prevailing approaches to manage autoimmune thrombotic disorders, such as heparin-induced thrombocytopenia, antiphospholipid syndrome and thrombotic thrombocytopenic purpura, include immunosuppression and systemic anticoagulation, though neither provides optimal outcome for many patients. A different approach is suggested by the concurrence of autoantibodies and their antigenic targets in the ab...
