Myocardial work in idiopathic premature ventricular contractions: Assessing left ventricular function and prognosis

Background Premature ventricular contractions (PVCs) can lead to impairment of left ventricular function. The noninvasive myocardial work technique, which incorporates left ventricular afterload, represents a new method for assessing left ventricular functional. Aim The aim of this study is to explore the value of noninvasive myocardial work technique in assessing left ventricular systolic function in patients with PVCs. Methods Compare the clinical data, two‐dimensional echocardiography parameters, and myocardial work parameters of 66 patients with PVCs and 35 healthy volunteers and explore the relevant risk factors for postoperative recurrence in patients with PVCs. Results In patients with PVCs compared to the control group, they exhibit enlargement of left atrial diameter (LAD) and left ventricular internal dimension in diastole (LVIDd), as well as thickening of the left ventricular wall. The global work waste (GWW) increases, while the global work efficiency (GWE) decreases. There is a significant negative correlation between the PVC burden and GWE (r = −0.70, p
