Brief Summary
Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridian phenomenon are urgently needed. Therefore, this study is designed to assess the metabolic characteristics of meridian phenomenon for the Heart and Lung meridians by using near infrared spectroscopy. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.

Outcome Measures
Primary Outcomes (1)
Regional oxygen saturation (rSO2)
Regional oxygen saturation could reflect the metabolic characteristics of meridians phenomenon.
5 minutes
Study Arms (2)
CSAP group
This group will include 40 patients with chronic stable angina pectoris (CSAP).
Healthy group
This group will include 40 healthy volunteers.
Interventions
Near infrared spectroscopy will be adopted to assess the microcirculatory characteristics of meridian phenomenon for participants in the two groups. 1. Experimental device: a four-channel INVOS 5100C Oximeter (Somanetics Corp., Troy, USA) 2. Experimental process: The participants will be allowed to stabilize for 15 minutes in a supine position in the experimental room before formal examination. They are asked to keep silent, breathe normally and avoid movement of limbs during the whole measuring period. After ripping the transparent adhesive tape on the probe, the probes will be left at 4 measuring sites. Regional oxygen saturation (rSO2) will be recorded for 5 minutes. 3. Measurement sites: Shenmen (HT7) and Shaohai (HT3) of the Heart meridian, Taiyuan(LU9) and Chize (LU5) of the Lung meridian.
Eligibility Criteria
40 patients with chronic stable angina pectoris (CSAP) and 40 healthy volunteer.
You may qualify if:
- Patients should meet the diagnostic criteria of coronary heart disease, which includes the following items: 1)confirmed old myocardial infarction (MI), or a history of percutaneous coronary intervention(PCI), or coronary artery bypass grafting; 2)50% or more luminal stenosis in at least one coronary artery or major branch segment confirmed by coronary angiogram or CT angiography; 3) myocardial ischemia indicted by exercise stress radionuclide myocardial imaging; 4) treadmill exercise testing is positive (for male patients);
- Patients should meet the diagnostic criteria of CSAP and the Canadian Cardiovascular Society(CCS) classification for CSAP is level II or III;

- Patients' chest pain is caused by non-cardiac disease (such as severe neurosis, climacteric syndrome, cervical spondylosis, and esophageal/pulmonary/chest wall lesions);
- Patients have concomitant conditions of lung diseases, such as COPD;
- Patients have serious concomitant conditions and and fail to treat them effectively, such as diseases of the digestive, urinary, respiratory, hematological and nervous system;
- Patients have mental illness, severe depression, alcohol dependence or history of drug abuse;
- Pregnant or lactating patients;
