Abstract

Background: Despite improvements in treatment of ST-segment myocardial infarction (STEMI), thrombus formation in the left ventricle is still a concerning complication that may lead to systemic thromboembolism and stroke.

Objectives: To evaluate the predictive value of estimated whole blood viscosity (WBV) for left ventricular thrombus development in patients surviving an acute anterior myocardial infarction (AAMI).MATERIALS \& METHODS:Seven hundred eighty AAMI patients who were treated percutaneously were enrolled consecutively. Serial echocardiographic examinations were performed within 24h of admission, before hospital discharge, and at 1, 3, 6 and 12 months following hospital discharge. WBV was calculated according to de Simones formula.

Results: One hundred patients (12.8%) developed thrombus formation within one year following AAMI. Patients with left ventricular thrombus (LVT) had significantly higher WBV values. Supramedian values of WBV at both low (0.5 sec-1) and high (208 sec-1) shear rates were found to be an independent predictor of LVT development.

Conclusion: As an easily accessible parameter, WBV might be a useful predictor of LVT formation within one year following acute anterior myocardial infarction.

de Simeone公式估计的全血粘度在急性前壁心肌梗死后一年内预测左室血栓形成的有效性。

背景:尽管st段心肌梗死(STEMI)的治疗有所改善，但左心室血栓形成仍然是一个令人担忧的并发症，可能导致全身性血栓栓塞和中风。目的:评价全血黏度(WBV)对急性前壁心肌梗死(AAMI)患者左室血栓形成的预测价值。材料与方法:连续纳入经皮治疗的780例AAMI患者。入院24小时内、出院前、出院后1、3、6和12个月进行超声心动图检查。WBV根据de Simones公式计算。结果:100例(12.8%)AAMI术后1年内发生血栓形成。左室血栓(LVT)患者WBV值明显升高。低剪切速率(0.5秒-1)和高剪切速率(208秒-1)下的WBV超中值是LVT发展的独立预测因子。结论:作为一个容易获得的参数，WBV可能是预测急性前壁心肌梗死后一年内LVT形成的有用指标。

期刊介绍： Biorheology is an international interdisciplinary journal that publishes research on the deformation and flow properties of biological systems or materials. It is the aim of the editors and publishers of Biorheology to bring together contributions from those working in various fields of biorheological research from all over the world. A diverse editorial board with broad international representation provides guidance and expertise in wide-ranging applications of rheological methods to biological systems and materials. The scope of papers solicited by Biorheology extends to systems at different levels of organization that have never been studied before, or, if studied previously, have either never been analyzed in terms of their rheological properties or have not been studied from the point of view of the rheological matching between their structural and functional properties. This biorheological approach applies in particular to molecular studies where changes of physical properties and conformation are investigated without reference to how the process actually takes place, how the forces generated are matched to the properties of the structures and environment concerned, proper time scales, or what structures or strength of structures are required.
