Nghiên cứu tỷ lệ và đặc điểm ứ huyết phổi ở bệnh nhân suy tim bằng siêu âm phổi

Abstract

Objective: To investigate the rate and characteristics of pulmonary congestion by pulmonary ultrasound in heart failure patients. Subject and method: A prospective, descriptive and cross-sectional study on 60 heart failure patients treated at Cardiovascular Center, 103 Military Hospital  from January 2022 to August 2022. The patients underwent clinical examination, laboratory tests and lung ultrasound (evaluation of pulmonary congestion through the presence of pleural effusion and B-line sign). Result: The rate of pulmonary congestion was 76.67%, in which isolated pleural effusion was 11.67%, isolated B-line sign was 28.33%, pulmonary congestion determined by both pleural effusion and B-line was 36.67%. Pleural effusion was present in 48.33% of patients and their distribution was: 33.33% bilateral, 11.67% isolated right-sided, 3.33% isolated left-sided. The mean B-line score was 4.65 ± 2.19. The distribution of B-line was irregular. The number of B-line in the lateral zones were higher than those in the anterior zones, the lateral inferior zones on each side (zone 4 and zone 8) was the zones had the highest number of B-lines. B-line score correlated positively moderately with NYHA class (r = 0.323; p<0.05), NT-proBNP concentration (0.454, p<0.05). Conclusion: Most patients had pulmonary congestion (76.67%) with image of pleural effusion and or B-line sign on ultrasound. Pulmonary congestion on the right side was more severe on the left side. Pulmonary congestion correlated with severity of heart failure and NT-proBNP concentration.
