This article reviews the currently available antiplatelet therapies and emerging investigational drugs in the treatment of acutecoronary syndrome (ACS), and considerations for primary and secondary prevention in the long-term management of ACS patients undergoing percutaneous coronary intervention (PCI). ⋯ Current antiplatelet therapies have clinical benefits such as reducing immediate and long-term cardiovascular risk, but substantial residual risk remains indicating a need for new therapeutic agents. Additional large randomized trials are necessary to determine the most appropriate treatment regimens for ACS patients.

Review published clinical trial studies on pharmacological treatment of stroke using both the Barthel Index (BI) and Modified Rankin Scale (MRS) as outcome measures, and to highlight the differences in psychometric properties and cut-off scores through a systematic review. ⋯ Despite the lack of uniformity in the cut-off points used in the trials, the follow-up time after administration of therapy, and the amount of time within which treatment is initiated after onset of stroke symptoms, the MRS seems to be more sensitive and responsive as compared to the BI in measuring stroke disability. However, more studies are required to differentiate the BI and the MRS that would help in selecting a scale that would appropriately capture outcomes among stroke patients.
