Abstract:
To investigate whether ischemic postconditioning (IPTC) can promote the recovery of left ventricular impaired regional or global longitudinal systolic function.
Methods: The trial was divided into a percutaneous coronary intervention (PCI) group, an PCI+IPTC group and a control group. Thirty-two patients with anterior acute anterior wall ST-segment elevation myocardial infarction (STEMI) underwent the first emergency PCI in the PCI group, 28 patients with anterior acute STEMI underwent the combination of PCI and IPTC in the PCI+IPTC group, while 30 patients underwent coronary angiography in the control group. Two-dimensional dynamic echocardiography was collected before operation, 0.5 h, 1 day, 3 days, 1 week, 1 month and 6 months after operation, respectively. The longitudinal strain parameters at different time points were analyzed and compared in the 3 groups.
Results: The regional longitudinal strain of infracted segments in the PCI+IPTC group after the operation within 1 week was higher than that in the PCI group (P<0.05). The left ventricular global longitudinal strain in the PCI+IPTC group seemed to be higher than that in PCI group after the operation within 1 week, but there was not statistically difference (P>0.05). There was no significant difference in the long-term regional and global longitudinal strains of left ventricle between the PCI+IPTC group and the PCI group (both P>0.05).
Conclusion: The IPTC can improve the short-term longitudinal systolic function of the reperfused myocardium in patients with acute anterior wall STEMI after PCI.
