Diagnostic value of internal jugular vein collapsibility index in acute decompensated heart failure through comparison with findings of echocardiography and P-BNP level in patient with dyspnea

Abstract

Background: Accurately diagnosis of heart failure in patients with dyspnea can be difficult because clinical history and physical examination are often non diagnostic and may be inaccurate, especially when patients have complicated comorbid conditions. This study aimed to achieve an easy method for diagnosis of acute heart failure through measuring and calculating internal jugular collapsibility index by ultrasound in comparison with echocardiography and P-BNP level and find a new method and standard for diagnosis of acute heart failure. Materials and Methods: This diagnostic study was done on 120 patients referring to Al-Zahra Hospital with complaints of shortness of breath who were screened based on the Framingham criteria. Demographic information, vital signs and history of heart disease were recorded and then, the AP diameter of internal jugular vein (IJVD)(respiratory variation) was measured. P-BNP and echocardiography were done. The results of tests and echocardiogram and calculations of IJV-CI were collected and statistical analysis was done in two descriptive and analytical parts. Results: Based on echocardiography left ventricular heart failure in 72.3 of patients was positive and in 27.7 of patients was negative. The severity of heart failure in 44.2 of patients was mild, in 41.9 was moderate and in 13.9 was severe. The mean of IJV-CI and IVC-CI in positive patients were significantly lower than negative patients (P-values > 0.05). The mean of pro-BNP in positive patients was significantly higher than negative patients (P-values = 0.0001). Conclusion: Pro-BNP and sonographic assessment of IJV-CI and IVC-CI by emergency physicians may be used as a rapid and simple method for diagnosis of left ventricular heart failure in patients with dyspnea in emergency department. © 2018, Advanced Scientific Research.
