Acute Myocardial Infarction (AMI), Cardiac Rehabilitation, Drug-coated Balloon, Enhanced External Counterpulsation (EECP)
Conditions
Brief summary
This study evaluated the efficacy and safety of enhanced extracorporeal counterpulsation for cardiac rehabilitation in patients after DCB for acute myocardial infarction.
Interventions
patients in the control group received antiplatelet agents (100 mg of aspirin and 75 mg of clopidogrel, once a day), β-blocker (25-100 mg of metoprolol, twice a day, with the dose adjusted based on the patient's heart rate) and statins (10-20 mg of rosuvastatin, every night). In addition, the patients received exercise rehabilitation (e.g. aerobic, resistance and flexibility training) for 30-60 min, 3-5 times/week.
Patients in the rehabilitation group received the same medication and exercise rehabilitation as the control group during the trial period after undergoing DCB-based PCI DCBs; in addition, they were provided with EECP treatment after 7 days of medication. The treatment adopted a P-ECP/TI EECP device with a pressure setting of 0.020-0.035 MPa. Based on patients' actual tolerance, the treatment pressure and inflation and exhaust times were adjusted to a diastolic/systolic blood pressure ratio of \>1.2 and a diastolic/systolic pressure area of 1.5-2.0. The treatment was applied daily for 1 hour, 6 days a week, for a total of 36 hours.

* patients with AMI diagnosed based on the universal definition of myocardial infarction criteria * a single vessel infarcted, and Syntax score ≤22 * patients treated using DCB * patients without EECP contraindications * patients aged 18-75 years * patients who had signed informed consent and were able to cooperate in completing the study
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of baseline data | followed up for 6 months | Patients' gender |
| Comparison of cardiac function | followed up for 6 months | In the indicators, including the CO, SV and LVEF |
| Comparison of brain natriuretic peptide levels | followed up for 6 months | BNP levels. |
| Comparison of 6-minute walking distance | followed up for 6 months | The 6MWD in the rehabilitation group. |
| Comparison of cardiac function gradings | followed up for 6 months | The New York Heart Association(NYHA )scale classifies impaired heart function into four levels according to the degree of activity that triggers symptoms of heart failure. A higher grade indicates more severe symptoms. |
| Comparison of cardiac angina gradings | followed up for 6 months | The Canadian Cardiovascular Society (CCS) grading system for angina pectoris is divided into four levels, with different treatment options. A higher grade indicates more severe symptoms. |
