Résumé
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.
Résumé
OBJECTIVE@#To investigate the alteration of plasma levels of omentin-1 and visfatin in elderly patients with coronary heart disease (CHD) and heart failure.@*METHODS@#Plasma omentin-1 and visfatin levels were measured in 90 subjects (29 stable angina pectoris (SAP) cases, 30 unstable angina pectoris (UAP) cases and 31 age- and sex-matched healthy controls (age ≥ 60 years) by enzyme-linked immunosorbent assay methods. According to the New York Heart Association classification, 59 CHDs were divided into three groups: functional I class, 11 cases; functional II/III class, 36 cases; and functional IV class, 12 cases.@*RESULTS@#The plasma level of omentin-1 in CHD patients was significantly lower than that of the control group. Omentin-1in SAP group and UAP group were significantly lower compared to the control group (there was no statistical significance between UAP group and SAP group; P >0.05). The plasma level of visfatin in CHD patients was significantly higher than that of the control group. Similarly, visfatin in SAP group and UAP group were all significantly higher compared to the control group, while there was no statistical significance between UAP group, and SAP group. The plasma omentin-1 level was negatively correlated with SBP (r=-0.264, P<0.05), positively correlated with HDL-c level (r=0.271, P<0.05); the plasma visfatin level was positively correlated with TC (r=0.292,P<0.05), negatively correlated with HDL-c level (r=-0.266,P<0.05). There was a negative correlation between plasma omentin-1 and visfatin levels (r=-0.280, P<0.05). Moreover, multiple linear stepwise regression analysis showed that omentin-1 and visfatin levels might be affected by HDL-c level. Logistic regression analysis showed that visfatin could be an independent risk factor of CHD.@*CONCLUSIONS@#Decreased levels of omentin-1 and increased levels of visfatin may be involved in the occurrence and development of CHD. Omentin-1 and visfatin, independently, may be protective and pro-inflammatory cytokines. Additionally, both omentin-1 and visfatin may be related to lipid metabolism. Visfatin may be an independent risk factor of CHD.
