Association of PC and AT levels in the early phase of STEMI treated with pPCI with LV systolic function and 6-month MACE.

Objectives: To examine a relationship between protein C (PC) and antithrombin III (AT III) activities with ejection fraction of left ventricle (EFLV), in the early phase of acute ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), and to investigate whether PC and AT III are associated with major adverse cardiovascular events (MACE) within 6 months following from pPCI.

Patients And Methods: The research had a prospective character and included 357 patients who had, following the diagnosis of the STEMI, undergone pPCI at the Clinic of Cardiology and Emergency Internal Medicine, Military Medical Academy, Belgrade, Serbia, from January 2010 until April 2019.

Results: The EFLV positively correlated with PC values (rho = 0.

Lower plasma protein C activity is associated with early myocardial necrosis and no-reflow phenomenon in patients with ST elevation myocardial infarction.

Activity of protein C has important role in the development of early necrosis and no-reflow phenomenon in patients with ST-segment elevation myocardial infarction (STEMI) after successful primary percutaneous coronary intervention (pPCI). We examined association between plasma activity of protein C, antithrombin, coagulation factors II, VII, VIII and fibrinogen to early formation of new Q-waves (myocardial necrosis) before pPCI and early ST-segment resolution (microcirculatory reperfusion) after pPCI in patients with acute STEMI. According to ischaemic time, patients were considered as early or late presenters.

Very late stent thrombosis of bare-metal coronary stent nine years after primary percutaneous coronary intervention.

Introduction: Stent thrombosis (ST) in clinical practice can be classified according to time of onset as early (0–30 days after stent implantation), which is further divided into acute (< 24 hours) and subacute (1–30 days), late (> 30 days) and very late (> 12 months). Myocardial reinfaction due to very late ST in a patient receiving antithrombotic therapy is very rare, and potentially fatal. The procedure alone and related mechanical factors seem to be associated with acute/subacute ST.

Iatrogenic dissection of the left main coronary artery during elective diagnostic procedures--A report on three cases.

Unlabelled: INTRODUCTION. Left main coronary artery dissection is a rare and potentially life-threatening complication of coronary angiography and angioplasty which requests urgent revascularization.

Case Report: During the period between 2010 and November 2014 at single healthcare center we did totally 8,884 coronary procedures, out of which 2333 were percutaneous coronary interventions (PCI).

Successful primary percutaneous coronary interventions in a patient with two consecutive ST-segment elevation myocardial infarctions and dual left anterior descending artery (type IV).

Introduction: Dual left anterior descending (LAD) artery is a very rare inherited anomaly. It can be incidentally revealed during primary percutaneous coronary intervention (pPCI) and may produce difficulties in detecting and treating the culprit lesion.

Case Report: We presented a 52-year-old male patient with ST-segment elevation myocardial infarction (STEM1) of inferior wall, in whom dual LAD anomaly was revealed during pPCI: a short LAD artery originated from the left main coronary artery and a long LAD artery originated from the proximal part of the right coronary artery (RCA).
