Brief summary
The aim of this Real-world study in China is evaluating the Safety and Efficacy of Paclitaxel Eluting Balloon Catheter in Coronary de-novo lesions(target vessel diameter:2.5mm-4.0mm)Treatment. And the primary point of this study is the target lesion failure of 12 months after surgery.

Inclusion criteria
1. 18-78 years of age, male or non-pregnant female; 2. patients with asymptomatic or symptomatic myocardial ischemia, stable or unstable angina pectoris, myocardial infarction with a course of more than two weeks, and patients with indications for percutaneous coronary intervention; 3. the target lesions were primary, in situ coronary artery stenosis, located on one or two different coronary artery vessels, the number of target lesions on each coronary artery was not more than one; 4. the length of the target lesion ≤ 26mm (visual), which can be covered by a single drug balloon (it is suggested that the balloon should cover at least 4mm healthy partition, 2 mm at each end; The reference diameter of target vessel was 2.5mm-4.0mm (visual); 5. the stenosis degree of the target lesion was ≥ 70%; 6. left ventricular ejection fraction ≥ 45%. 7. patients who can understand the purpose of the trial, voluntarily participate and sign informed consent, and are willing to follow up the study.
Exclusion criteria
Related to patients: 1. patients with myocardial infarction within two weeks; 2. pregnant or lactating women; 3. cardiogenic shock, acute infection, known bleeding or coagulation disorder, or active digestive tract; Patients with history of hemorrhage or ulcer, cerebral hemorrhage or subarachnoid hemorrhage, stroke within half a year; 4. patients with a life expectancy less than one year or with difficulties in clinical follow-up; 5. patients who had a history of PTCA or had other operations scheduled during the follow-up period of one year; 6. patients who are participating in any other clinical study and who have not reached the main end point of the study; 7. present or previous history of severe liver disease, and / or renal impairment: serum creatinine \> 2.0 mg / dl( 176.8 umol / L) or undergoing hemodialysis therapy. Therefore, it does not meet the requirements of angiography; 8. patients with left ventricular ejection fraction below 45%; 9. for other reasons, the researchers did not think it was appropriate for a patient to be selected. Related to lesions: 1. left main lesion and the bifurcation with side branch \>2.5 mm; 2. the location of the lesion was less than 10 mm at the proximal end of the anterior descending branch, 5 mm in the circumflex branch and 5 mm in the proximal end of the right coronary artery. 3. severe calcification and twisted lesions which can not be successfully predilated, are not suitable for drug balloon delivery and expansion. 4. lesion length ≥ 26 mm; 5. evidence of severe thrombosis in target vessels before intervention; 6. lesions that cannot be treated with PTCA or other interventional techniques; 7. after predilation of the target lesion, residual stenosis ≥ 30% or TIMI blood flow \< 3, and / or obvious flow limiting dissection.
