Effect of Enhanced External Counterpulsation

Effect of Enhanced External Counterpulsation on the Rehabilitation of Patients With Acute Myocardial Infarction After Drug-Coated Balloon-Based Percutaneous Coronary Intervention

This study evaluated the efficacy and safety of enhanced extracorporeal counterpulsation for cardiac rehabilitation in patients after DCB for acute myocardial infarction.

Inclusion Criteria:

• 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:

• patients with lower limb deep venous thrombosis and active thrombophlebitis
• patients with moderate to severe valvular heart disease, especially those with aortic insufficiency and/or stenosis
• patients with moderate to severe pulmonary arterial hypertension (mean pulmonary arterial pressure >50 mmHg)
• patients with aortic, cerebral or dissecting aneurysms
• patients with uncontrolled hypertension (>180/110 mmHg)
• patients with decompensated heart failure (cardiac function of grade IV)
• patients with arrhythmia that might interfere with the electrocardiographic gating function of the EECP device
• patients with haemorrhagic diseases or obvious bleeding tendencies
• patients with infected lesions in their limbs that may affect EECP
• pregnant women
• patients with ventricular aneurysm and mural thrombus detected through echocardiography
