In patients with ACS, the rates of MACEs and NACEs were not significantly lower with bivalirudin than with UFH, irrespective of planned GPI use. However, bivalirudin significantly reduced bleeding complications, mainly those not related to access site, irrespective of planned use of GPIs.

We study the kinetics after a low temperature quench of the
one-dimensional Ising model with long range interactions between spins
at distance rr
decaying as r^{-\alpha}r−α.
For \alpha =0α=0,
i.e. mean field, all spins evolve coherently quickly driving the system
towards a magnetised state. In the weak long range regime with
\alpha >1α>1
there is a coarsening behaviour with competing domains of opposite sign
without development of magnetisation. For strong long range,
i.e. 0<\alpha <10<α<1,
we show that the system shows both features, with probability
P_\alpha (N)Pα(N)
of having the latter one, with the different limiting behaviours
\lim _{N\to \infty}P_\alpha (N)=0limN→∞Pα(N)=0
(at fixed \alpha<1α<1)
and \lim _{\alpha \to 1}P_\alpha (N)=1limα→1Pα(N)=1
(at fixed finite NN).
We discuss how this behaviour is a manifestation of an underlying
dynamical scaling symmetry due to the presence of a single
characteristic time \tau _\alpha (N)\sim N^\alphaτα(N)∼Nα.
Aims The impact of reperfusion delay in ST-elevation myocardial infarction (STEMI) is well known. We aimed to describe the specific reasons for delay to primary percutaneous coronary intervention (pPCI), and their impact on mortality after adjusting for confounders, using the firstmedical-contact-to-device (FMCTD) time to measure the delay.
A progressive transition from TF to TR-pPCI could be implemented over a 4-year period without increasing overall treatment delay. The impact of operator experience on procedural results appeared to be modest and it did not differ in the study access groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
