Abstract

Objective

Inflammation plays a critical role in atherosclerosis. This study examines the effects of ticagrelor and clopidogrel on inflammatory parameters, obtained from complete blood count (CBC) and biochemical measurements, in patients with acute coronary syndrome.

Methods and Results

One hundred acute coronary syndrome (ACS) patients were included in the study and grouped according to clopidogrel (n = 50) or ticagrelor (n = 50) usage as an anti-aggregant (with acetylsalicylic acid). All patients underwent percutaneous coronary intervention. On admission, at third- and sixth-month after ACS, white blood cell (WBC) count, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-high-density lipoprotein ratio (MHR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) were calculated from the CBC and biochemical measurements. NLR, PLR, and SII were significantly lower in the ticagrelor group (p < 0.001, at 3rd and 6th month). Also, MHR was lower in the ticagrelor group (p < 0.05). Conversely, WBC count was higher in the ticagrelor group (p < 0.001).

Conclusions

NLR, MHR, PLR, and SII levels were lower in ACS patients treating with ticagrelor. Ticagrelor may improve these inflammatory parameters in percutaneous coronary intervention (PCI)-treated ACS patients compared to clopidogrel.
