ABSTRACT
Background: Heart failure is a clinical syndrome that causes impaired ventricular filling. Its progression along with hypertension can cause ventricular enlargement, ventricular diastolic dysfunction, ventricular remodeling resulting in P waves alteration, one of which is P Wave dispersion, and structure of anatomical alterations as evaluated by an echocardiography. However, the examination is still limited to first-level health facilities. Therefore, an easily available and used initial examination is necessary, such as an electrocardiogram (EKG) by assessing the P wave dispersion which describes the left ventricular mass index (LVMI). Thus, this study aims to assess the correlation between P wave dispersion and the left ventricular mass index (LVMI) in heart failure patients at H. Adam Malik Hospital.
Method: This retrospective observational study with a cross-sectional design was conducted in June – December 2023 at H Adam Malik General Hospital, Medan. The sample included all chronic heart failure patients from January – June 2023 at H Adam Malik Hospital Medan who met the inclusion and exclusion criteria. Electrocardiogram and echocardiography data were recorded, then data analysis was carried out.
Results: A total of 60 subjects were included and divided into samples with an average P wave dispersion of ≥36 ms and <36 ms, and left ventricular mass index (LVMI) of 189.2 g/m2 (men) and 172.8 g/m2 (woman). There is a significantly moderate correlation between P wave dispersion and left ventricular mass index (LVMI) (r= 0.462, p = 0.001).
Conclusion: There is a correlation between P wave dispersion and left ventricular mass index (LVMI) in heart failure patients at H. Adam Malik General Hospital.
Keywords: heart failure. electrocardiography, p wave dispersion, left ventricular mass index.
