BACKGROUND: Rapid reperfusion has been shown to decrease mortality and improve left ventricular (LV) function. Previous studies have reported that LV thrombus (LVT) is a major complication of ST-segment elevation acute anterior wall myocardial infarction (AMI). There are little data on LVT in the current primary percutaneous coronary intervention (PPCI) ...

OBJECTIVE: The development of left ventricular remodelling (LVR) after acute myocardial infarction (AMI) is a predictor of heart failure and mortality. The extracellular matrix (ECM) is highly susceptible to ischaemic injury. Laminin and collagen type VI (CVI) contribute to ECM formation in the infarct zone. To determine whether these markers ...

Myocardial infarction is the combined result of environmental factors and personal predispositions. Prothrombotic factors might play an important role in this phenomenon. Annexin V (ANV) is a calcium-dependent glycoprotein widely present in various tissues exerting a potent anticoagulant effect in vitro by reducing plaque adhesion and aggregation. Anti-annexin V antibodies ...
