简要总结
The general purpose of the Neomindset trial is to evaluate the non-inferiority hypothesis for ischemic events and the superiority hypothesis for bleeding events resulting from platelet P2Y12 receptor inhibitors given as monotherapy in comparison with conventional dual antiplatelet therapy in acute coronary syndrome patients treated with percutaneous coronary intervention.
The platelet sub-study will be conducted at the Hospital Israelita Albert Einstein. This sub-study will recruit randomized patients from the Neomindset trial to evaluate platelet function after at least 30 days of study treatment with either P2Y12 inhibitor monotherapy or dual antiplatelet therapy.
详细描述
The platelet sub-study will be conducted at the Hospital Israelita Albert Einstein. This sub-study will recruit randomized patients from the Neomindset trial to evaluate platelet function after at least 30 days of study treatment with either P2Y12 inhibitor monotherapy or dual antiplatelet therapy.
These patients will undergo blood sampling and measurement of platelet function after being treated with P2Y12 inhibitor monotherapy or dual antiplatelet therapy for at least 30 days.
