Antiplatelet agents play an essential role in the treatment of acute coronary syndrome (ACS). Thienopyridines are a class of drugs that function via inhibition of the adenosine diphosphate (ADP) P2Y12 platelet receptors. Currently, clopidogrel, a second generation thienopyridine, is the main drug of choice and the combination of aspirin and clopidogrel is administered orally for the treatment of ACS. ⋯ Ticagrelor compared with clopidogrel had a significantly greater reduction in the death rate from vascular causes, myocardial infarction, or stroke without major bleeding. There was however, an increase in non-procedure related bleeding, dyspnoea and ventricular pauses in the first week of treatment. Further studies on new antiplatelet agents are needed to establish a new "gold standard" antiplatelet therapy.

Although the flow velocities of portal veins (PV) and flow patterns of hepatic veins (HV) during pregnancy were evaluated in the literature, changes in PV flow pattern during pregnancy have not been assessed. The aim of this study was to detect changes in HV and PV flow velocities and patterns during pregnancy. ⋯ When evaluating physiological changes in pregnancy, flow pattern changes of the HV and flow velocity changes of the PV may be accepted as sensitive parameters and may be indicators of physiological alterations related to pregnancy.
