Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients with confirmed CMVD angina; 2. 18 years old <= age <= 75 years old, gender is not limited; 3. If the patient has a history of PCI implantation, patients with postoperative coronary stenosis <=50% are required [patients who have completed relatively complete revascularization after PCI and also meet the diagnosis of CMVD (no stenosis greater than 50%) can be enrolled in the trial, and are excluded if they are elective or untreated]; 4. Voluntarily participate in this clinical study and sign an informed consent form.
Exclusion criteria
Exclusion criteria: 1. Acute heart failure or acute coronary syndrome; 2. Severe aortic stenosis or coarctation, pulmonary embolism, hypoglycemia (less than 5.5 mmol/L), or severe high/low blood pressure (diastolic blood pressure greater than 210 mmHg or less than 90 mmHg) that does not tolerate exercise loads; 3. Women who are pregnant or breastfeeding; 4. Those with a life expectancy of <2 years due to a combination of malignant tumors or other diseases; 5. Severe lung disease (acute and chronic respiratory failure and moderate or more pulmonary fibrosis, lung damage, etc.); 6. Drugs that dilate blood vessels or temporarily improve myocardial blood supply (e.g., nitrate drugs or ß-blockers, other proprietary Chinese medicines) or drugs that affect cardiac waveforms (e.g., digitalis, antiarrhythmics: amiodarone, etc., phenothiazines, tricyclic, epinephrine, norepinephrine/isopropyl epinephrine, vagotoxin, arsenic agents) taken within 48 hours before the test; 7.
