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.

Inclusion Criteria:

1. Patients with clear diagnosis of hypertension (≥1 year, drug control within 140/90mmHg); (2) Significant coronary artery stenosis was excluded by imaging within 1 year (≤50%); (3) Age between 18 and 80.

Exclusion Criteria:

1. CHD, heart valve disease, congenital heart disease, cardiomyopathy and pericardial disease; (2) Left ventricular ejection fraction (LVEF) <50%; (3) Increased markers of myocardial injury; (4) Diabetes mellitus, connective tissue disease, chronic obstructive pulmonary disease and malignant tumor; 5) Severe hepatic and renal impairment (Cr ≥120 umol/L, ALT ≥120 umol/L); 6) Pregnant women.

The hypertensive patients with chest pain for suspicious coronary heart disease (CHD) in Peking University Third Hospital were seriesly enrolled. All the patients underwent coronary angiography or coronary CT angiography to exclude the diagnosis of OCAD.
