Abstract
BACKGROUND: Percutaneous coronary intervention (PCI) is an effective treatment for coronary artery disease. Previous studies have demonstrated the delayed effects of PCI on left ventricular diastolic and systolic function. However, the early impact on these parameters has not been systematically examined. Moreover, no study has compared the impact of revascularization on the global longitudinal (GLS) and circumferential (GCS) strains of the left ventricle. Using echocardiographic parameters, the present study aimed to investigate the reversibility of diastolic and systolic abnormalities in patients with significant coronary artery stenosis within 1 to 2 days after PCI. Additionally, this study will compare the effects on both global and longitudinal strains. METHODS: This study included 80 consecutive patients admitted to the angiography department for elective PCI with normal left ventricular function. Echocardiography was performed before PCI and 1 to 2 days post-procedure to assess left ventricular diastolic and systolic function indices in these patients. RESULTS: The mean age of the patients was 58.0±11.9 years, with a predominantly male cohort (65%). All the patients exhibited normal left ventricular systolic function and various degrees of diastolic dysfunction. One to 2 days after revascularization, significant improvements were observed in all diastolic function indices and GLS. However, no significant improvement was found in GCS. CONCLUSION: Revascularization of a significantly stenotic coronary artery can enhance diastolic function and systolic longitudinal strain of the left ventricular myocardium as early as 1 to 2 days, with no significant impact on GCS.
