Is Portable Cardiopulmonary Ultrasound the Future of Heart Failure Diagnosis?

Aim of the Study: Heart failure is a major problem of public health in Morroco , pulmonary congestion is a key sign which can be easly detected by pulmonary sonography via interlobular septal thickening. The aim of this study was to establish a link Between kerley B lines in the lung and signs of pulmonary congestion. In addition to assess the evolution of these parameters in response to diuretic treatment. Materials and Methods: We prospectively evaluate 118 patients who presented to the emergency of IBN Rochd Hospital in Casablanca with sensation of breathlessness at baseline, 7 days, one month and 3 months for kerley B lines, NYHA Class of dyspnea and the levels of NT pro bnp. the duration of this study was 4 months. Results: Kerley B lines were present in 87.4% of patients initially, 67.6% had elevated levels of NT-probnp and 53%,30%,16% had dyspnea Class II, III and IV respectively. Diuretic treatment have shown a similar improvement of kerley B lines, levels of NT pro bnp and the class of dyspnea . In deed after a follow up of 3 month : only 7 % of patients had persistant kerley b lines, NT pro bnp levels were high in only 7.6% these findings were concordant with the clinical symptomatolgy. Hence only 7% of our patients suffered from dyspnea at moderate efforts at the end of the study. Conclusion: We demonstrated in this study a positive correlation between kerley b lines and levels of NT pro-bnp. These findings may facilitate the orientation of patients within the emergency department and help to initiate heart failure treatment rapidely.
