Evaluation on the Safety of Ticagrelor Among Chinese ACS Patients

Study Overview
=================
Brief Summary
-----------------
The primary objective is to describe the safety and tolerability of ticagrelor, by assessment of adverse events (characteristics, reporting rate, severity, relationship and risk factors), especially the bleeding events as defined in 8.1 and other serious adverse events (SAEs) during 1-year follow up in Chinese acute coronary syndrome (ACS) patients.

Detailed Description
-----------------
The trial is a multi-centre, prospective cohort, non-interventional study to be conducted in the department of cardiology from approximately 20 tier-2 or 3 hospitals, China. The study requires Chinese subjects aged over 18, diagnosed as ACS and treated with ticagrelor at least one tablet from the department of cardiology in the around 20 tier-2 or 3 hospitals. The subjects will be tracked up to 1 month after the discontinuation of ticagrelor for AE events and 1 year after enrollment for major cardiovascular events. This is an observational study. The prescribing doctor is in charge of prescribing or discontinuation ticagrelor. The investigator in an observational study may not intervene in the treatment. All 1000 subjects' related data will be collected

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and tolerability of ticagrelor, by assessment of adverse events, especially the bleeding events and other SAEs during 1-year follow up in Chinese ACS patients. | a) Incidence of post-authorization adverse events including characteristics, reporting rate, severity, relationship and risk factors among Chinese ACS patients with ticagrelor during 1-year follow up b) PLATO-defined fatal/life-threatening bleedings during 1-year follow up in Chinese ACS patients treated with ticagrelor. c) PLATO-defined major bleedings during 1-year follow up in Chinese ACS patients treated with ticagrelor. d) PLATO-defined major + minor bleedings during 1-year follow up in Chinese ACS patients treated with ticagrelor. e) PLATO-defined major + minor + minimal bleedings during 1-year follow up in Chinese ACS patients treated with ticagrelor. f) Serious adverse events other than bleeding during 1-year follow up in Chinese ACS patients treated with ticagrelor | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of major cardiovascular (CV) events during 1-year follow up in Chinese ACS patients treated with ticagrelor. | Major CV events including CV death, MI and Stroke, during 1 year follow up in Chinese ACS patients treated with ticagrelor. Incidence of post-authorization adverse events among specific patients groups from Chinese ACS patients with ticagrelor. Survival free of major CV events among Chinese ACS patients with ticagrelor. Proportion of patients with discontinuation or interruption of ticagrelor and the reasons. | 1 year |
