The purpose of this study is to compare the effect of implementing wireless remote monitoring combined with structured telephone monitoring, versus current care, on variation in rehospitalization among older patients hospitalized with heart failure at six medical centers.

Ticagrelor is an oral, reversibly-binding, direct-acting P2Y12 receptor antagonist used clinically for the prevention of atherothrombotic events in patients with acute coronary syndromes (ACS). Guideline recommendations on the use of dual antiplatelet therapy (DAPT) have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for patients who have an ACS with or without ST-segment elevation. However, few East Asian patients (or those of East Asian descent) have been included in these trials to assess the use of these drugs. In Korea and Japan, it has been reported that low doses of ticagrelor might have a more potent inhibition of platelet aggregation (IPA) than clopidogrel (75 mg once daily) in healthy subjects and patients with stable coronary artery disease, respectively. But it is still not clear whether a low dose of ticagrelor is superior to clopidogrel in a large population of Chinese ACS patients. A recent study on pharmacokinetics and tolerability of ticagrelor has found that maximum plasma concentration and area under the plasma concentration-time curve of ticagrelor (90 mg twice daily) and its active metabolite (AR-C124910XX) tended to be approximately 40% higher in healthy Chinese volunteers compared with Caucasian subjects. This data also suggested that a low dose of ticagrelor might be more appropriate for Chinese ACS patients. In view of a large diurnal variation with a single daily dose, a lower dose twice daily may be a better choice for Chinese patients. Therefore, the investigators performed this randomized, single-blind, crossover clinical trial to observe the efficacy and safety of low-dose ticagrelor (22.5 mg twice daily) in comparison to clopidogrel (75mg once daily) in Chinese patients with stable coronary artery disease.
