Abstract

To observe the current status of β-blocker (BB) use and heart rate control in Chinese patients with stable coronary artery disease (SCAD) based on subgroup data of the prospective observational longitudinal registry of patients with stable coronary artery disease (CLARIFY). The CLARIFY study is an international prospective observational registry of outpatients with SCAD. From November 2009 to July 2010, patients with SCAD were enrolled, and demographic information, clinical indicators, medication and blood flow reconstruction were collected. Patients were divided in three mutually exclusive categories by baseline pulse palpation heart rate(HR)≤60 beats per minute (bpm)(n=397), 61-69 bpm(n=782), and ≥70 bpm(n=1 443). The patients were also divided into taking BB or not taking BB groups. The aim of present study is to describe and analyze the current status and factors related to the HR control and BB use in the Chinese subgroup of CLARIFY. A total of 2 622 patients were enrolled from 56 centers across China. The mean age was (63.6±10.3) years old with 75.6% (1 983) male patients, 55.0% (1 443) patients had HR≥70 bpm. Mean HR measure by electrocardiogram(ECG) was (69.4±10.2)bpm, 50.9% (1 334 cases) patients had myocardial infarct...Continue Reading
