This study assessed anxiety status and coronary flow reserve in hypertensive patients to investigate the effects of anxiety on coronary microcirculatory function.The hypertensive patients with chest pain for suspicious coronary heart disease were seriesly enrolled. All the patients underwent coronary angiography or coronary CT angiography to exclude the diagnosis of obstructive coronary artery disease . Coronary flow reserve (CFR) is an integrated measure of flow through both the large epicardial arteries and the coronary microcirculation. In the absence of obstructive stenosis of the epicardial arteries, CFR is an indicator of coronary microcirculatory function，which can be assayed by Transthoracic Doppler echocardiography. The symptoms of anxiety were measured with Self-rating Anxiety Scale (SAS) . According to the SAS score,the patients were divided into anxiety group and non-anxiety group.We assessed the association of anxiety with coronary microcirculatory function.
