Effects of Elective Percutaneous Coronary Intervention on Subtle Left Ventricular Systolic Dysfunction in Patients With Stable Coronary Artery Disease as Assessed by Global Longitudinal Strain Imaging.

Aim The study aimed to detect subtle left ventricular (LV) systolic dysfunction, reflected by abnormal global longitudinal strain (GLS), in patients with stable coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) and to evaluate any improvement in GLS at 24 hours and six months post-PCI. Methods A total of 94 patients with stable CAD scheduled for elective PCI at our hospital were evaluated using conventional 2D echocardiography and GLS prior to the procedure. Follow-up assessments were conducted at 24 hours and six months post-PCI.
