Abstract
Premature ventricular contractions (PVCs) are characterized by early depolarizations of the ventricular myocardium and represent one of the most prevalent forms of cardiac arrhythmia. These contractions arise when electrical impulses are generated within the ventricles, rather than originating from the sinoatrial node, resulting in an irregular cardiac rhythm. Epidemiological studies indicate that PVCs affect approximately 1 to 4% of the general population; however, detection rates can surpass 40% in individuals subjected to ambulatory electrocardiogram (ECG) monitoring (, ). The clinical implications of PVCs exhibit considerable variability. While most cases are benign and asymptomatic, increasing studies indicate that frequent PVCs may result in diminished cardiac function, an increased risk of heart failure, and a heightened likelihood of sudden cardiac death (). Additionally, El Kadri et al. () demonstrated that the ablation of frequent PVCs in patients with nonischemic cardiomyopathy could enhance left ventricular function, implying that a considerable burden of PVCs may adversely impact cardiac performance. Recent evidence has further refined the clinical understanding and management of PVCs. Current literature indicates that the prognosis of PVCs varies substantially according to symptom burden, PVC frequency, underlying structural heart disease, and left ventricular function. Although many idiopathic PVCs are benign, frequent PVCs may contribute to PVC-induced cardiomyopathy, and timely identification of high-risk patients is therefore important. In terms of management, contemporary strategies include reassurance and observation for low-risk patients, lifestyle modification and pharmacological therapy for symptomatic patients, and catheter ablation for selected patients with frequent or symptomatic PVCs, particularly when PVC-induced cardiomyopathy is suspected. These advances have improved clinical decision-making; however, their successful implementation also depends on patients’ understanding of the disease, perceived risk, willingness to follow medical recommendations, and adherence to long-term monitoring and self-management (, ). Despite advancements in diagnostic and therapeutic strategies, including enhanced pharmacological interventions () and catheter ablation, a significant number of patients continue to lack essential information regarding PVCs. Many individuals remain uninformed about the etiology, potential risks, warning signs, and management options associated with PVCs. This issue is clinically relevant because inadequate disease-related knowledge may affect how patients interpret symptoms, decide whether to seek medical care, adhere to medication or follow-up recommendations, and engage in lifestyle modification. In particular, patients with benign or asymptomatic PVCs may experience unnecessary anxiety, whereas those with frequent PVCs or comorbid cardiovascular disease may underestimate the need for monitoring and management (). This deficiency in knowledge may generate unnecessary anxiety among asymptomatic patients or those not requiring treatment, while in patients with comorbidities or those needing therapy, it may lead to inadequate attention and suboptimal adherence to treatment regimens, ultimately compromising disease prognosis (). The necessity of patient education is underscored by clinical guidelines, including the 2022 ESC Guidelines for the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death () and the 2020 Chinese expert consensus on ventricular arrhythmias (). These guidelines support risk-based evaluation, individualized management, and appropriate patient counseling in ventricular arrhythmia care. More recent evidence from cardiovascular health literacy research also indicates that limited health literacy is associated with poorer disease-related knowledge, medication understanding, self-management, and cardiovascular outcomes, further supporting the need for targeted patient education in PVC management (). The Knowledge, Attitude, and Practice (KAP) framework is a widely utilized model in health research designed to assess individuals’ comprehension, beliefs, and behaviors related to specific health issues. This framework frequently draws upon behavioral theories, including the Health Belief Model () and the Theory of Planned Behavior (), thereby providing critical insights for the formulation of targeted interventions aimed at improving health outcomes (). Although the KAP framework has been extensively utilized in the context of various heart diseases (), there exists a substantial research gap regarding PVCs, despite their significant prevalence. A systematic review demonstrated that educational initiatives in cardiac rehabilitation for patients with coronary artery disease improved attendance and attitudes, indicating potential benefits for the management of PVCs (). These findings highlight the need for KAP studies
