A novel predictor of clinical outcomes in patients with heart failure with preserved left-ventricular ejection fraction: a pilot study.

abstract：:Coronary artery calcification (CAC) as measured by computed tomography is a strong predictor of coronary artery disease. The brachial intima-media thickness (IMT) was recently reported to be associated with cardiovascular risk factors. This study investigated the association of brachial IMT with CAC, which is a marker...
