Review Meta Analysis Comparative Study
Cangrelor versus clopidogrel in percutaneous coronary intervention: a systematic review and meta-analysis.
Cangrelor is a new antiplatelet agent that has been used in percutaneous coronary intervention (PCI) with mixed results. We aimed to review the evidence on the efficacy of cangrelor in comparison to clopidogrel in reducing ischaemic endpoints at 48 hours in patients undergoing PCI in large randomised trials. ⋯ Based on this meta-analysis, we did not find any difference in the risk of the primary composite efficacy endpoint of all-cause death, ischaemia-driven revascularisation, and myocardial infarction at 48hours between cangrelor and clopidogrel use. Given that cangrelor was associated with a lower risk of stent thrombosis, ischaemia-driven revascularisation and Q-wave myocardial infarction compared to clopidogrel, cangrelor can be considered as a suitable alternative during PCI.

Acute kidney injury (AKI) is a strong but rather late predictor of mortality after transcatheter aortic valve implantation (TAVI). Early clinically useful markers for the detection of AKI and prediction of outcome are needed in order to control and improve management of periprocedural complications after TAVI. The aim of our study was to assess the predictive value of the Doppler-based renal resistance index (RRI), which correlates inversely with effective renal blood flow and creatinine clearance, for AKI in patients undergoing TAVI and to evaluate its association with paravalvular aortic regurgitation (PAR). ⋯ Measurement of the Doppler-based RRI predicts risk for AKI and increased mortality rates at an early post-procedural time point and is related to the occurrence of more-than-mild paravalvular aortic regurgitation after TAVI.
