Methods: A cross-sectional descriptive study was conducted on 30 heart failure patients, including 13 males (43.33%) and 17 females (56.67%), with an average age of 69.8 years. All patients underwent right internal jugular vein ultrasound, assessing the crosssectional area change ratio before and during the Valsalva maneuver within 24 hours of hospital admission. A positive result was defined as a ratio <
0.6 (indicating right atrial pressure >
12 mmHg). Results: In our study, 19 patients (63.33%) had positive results, with an average cross-sectional area change ratio of 0.62. There were no statistically significant differences between the positive and negative result groups in terms of clinical features, laboratory tests, or heart failure etiology. The cross-sectional area change ratio had a weak correlation with left ventricular ejection fraction (r = -0.24, p >
0.05), but a stronger correlation with NT-proBNP (r = - 0.45, p <
0.05) and NYHA functional class (r = - 0.41, p <
0.05). Conclusion: The right internal jugular vein cross-sectional area change ratio correlates with NT-proBNP and NYHA functional class, both of which are independent prognostic factors for cardiovascular events in heart failure patients, as demonstrated in numerous studies.
