Stent thrombosis following bare-metal stent implantation: success of emergency percutaneous coronary intervention and predictors of adverse outcome

Abstract

Emergency PCI for treatment of stent thrombosis effectively restores vessel patency and flow. Patients presenting with stent thrombosis are at risk for recurrent myocardial infarction and recurrent stent thrombosis.

Case Report: INTRAPROCEDURAL STENT THROMBOSIS IN PERCUTANEOUS CORONARY ANGIOPLASTY

“…Acute Stent Thrombosis is an event typical chest pain that occurs suddenly with a change in the form of acute ischemic ECG picture in accordance with the distribution of the affected blood vessel arising <24 hours after the act of stenting in coronary interventions. In angiography, stent thrombosis is a complete or partial occlusion of the blood vessel segments mounted stent, with evidence of thrombus (Wenaweser et al 2005). According Brener et al (2013), issued by the ST category based on only ARC stent thrombosis events that arise after the patient out of the cardiac catheterization laboratory, not at the time of intra-procedural.…”

“…The use of dual anti-platelet therapy (ASA and clopidogrel) reduces the incidence of thrombosis but increase bleeding complications. The incidence of stent thrombo-sis could still occur at 0.5-2% in the case of elective PCI and more than 6% in the case of PCI with acute coronary syndromes despite using dual antiplatelet (Wenaweser et al 2005). In the CURRENT OASIS study comparing the use of clopidogrel dose of 150 mg/day for one week compared to the standard dose of 75 mg/day obtained a significant reduction definite or probable stent thrombosis (HR 0.69; 95% CI -0.87 0:56; P = 0.001) (Hamm et al 2011).…”

“…If found the phenomenon of slow flow or no flow, intracoronary adenosine and epinephrine can be given (Alfonso et al 2004). The success of overcoming the acute thrombosis, characterized by normal blood flow (TIMI 3 flow) with stenosis <50% (Wenaweser et al 2005).…”

“…0.03% of the number of events throughout the action PTCA. The presence of coronary dissection, requiring additional stents to overcome (Wenaweser et al 2005). Bradycardia is one of the complications that arise from the action PTCA.…”

“…But there kompilkasi Stent thrombosis (ST) coronary rare, but serious that can cause high morbidity and mortality (Palmerini et al 2011, Wenaweser et al 2005, Brener et al 2013. The incidence of ST is increased in patients undergoing PTCA with acute coronary syndromes, patients who have diabetes mellitus, or bifurcatio stenting in patients who stopped dual anti-platelet therapy (Brener et al 2013).…”
