OBJECTIVE
Association between inflammation and pro-thrombotic state has been described previously. Aim of the present study was to investigate if presence of left atrial (LA) thrombus or spontaneous echocardiographic contrast (SEC) in rheumatic mitral stenosis (MS) was related to neutrophil/lymphocyte ratio (NLR), and to determine predictive utility of the CHA2DS2-VASc risk stratification score in patients with mitral stenosis complicated by LA thrombus.

METHODS
NLR and CHA2DS2-VASc score of 188 patients with MS and 35 healthy controls were evaluated. All analyses were also conducted according to rhythm status, excluding control group.

RESULTS
Among patients with MS, there were 31 patients in thrombus-positive group, 142 patients in SEC-positive group, and 15 patients in thrombus/SEC-negative group. Among patients with MS and sinus rhythm (SR) (n=105; 55.8%); 9.5% of them had LA thrombus, and 78% of them had SEC. In the SR group, median NLR was significantly higher in thrombus-positive group compared with thrombus/SEC-negative and control groups (p<0.001). Among patients with MS and atrial fibrillation (AF); there was no significant difference regarding NLR according to thrombus and SEC presence (p=0.214). In both SR and AF groups, there was no significant difference according to SEC/thrombus presence regarding median CHA2DS2-VASc score (p>0.05).

CONCLUSION
Elevated NLR is related to presence of LA thrombus in patients with MS and SR. The utility of CHA2DS2-VASc score in patients with MS and SR complicated by LA thrombus is debatable, according to our results.
