Incidence and associated risk factors of LV clot among patients with myocardial infarction of Urmia Seyyed-O- Shohada heart center

Abstract

Background

Based on previous experiments with a limited number of samples, it seems that the use of anticoagulants

(heparin or subcutaneous high dose heparin) reduces by 50%of the progression of left ventricular embolism.

In this study, we determined to investigate the incidence and factors associated with left ventricular thrombus

in patients with acute myocardial infarction admitted to Seyyed-al- shohada University Hospital.

Methods

In this analytic cohort study, patients with myocardial infarction were included and risk factors of LV clot

following of myocardial infarction as, diabetes mellitus, smoking, hypertension, dyslipidemia, higher age,

gender, extent of cardiac involvement, LV diastolic dysfunction and reperfusion were evaluated. Also, other

echocardiographic parameters as LV size, LV systolic and diastolic dysfunction, assessed and recorded in a

check list. Finally effect of each factor on incidence of LV clot was evaluated separately.

Results

In our study, we found no significant association between underlying disease, diabetes, history of prior MI,

history of hyperlipidemia, smoking and SK infusion, but there was a significant association between the type

of MI and clots in the left ventricle. In this study, we found no significant association between the incidence of

thrombus within the left ventricle and Primary PCI. Also receiving Heparin and/or Enoxaparin and Metoral are

not significantly associated with LV clots. However, there is no significant association between LV size and

count of involved leads in the incidence of left ventricular thrombus.

Conclusion: Finally, according to the results of the study it can be said that the time from onset of the pain until

revascularization in the hospital, had an important role in preventing LV clots and the outcomes of the patient.

Key words: Incidence, risk factors, LV clot, myocardial infarction.
