RESUMO

BACKGROUND: Ceruloplasmin (Cp) is a serum protein that belongs to the family of α2-globulins and it is increased in patients with after acute myocardial infarction complicated with heart failure. Aim of the study was to investigate levels of serum Cp in patients with acute decompensated heart failure. MATERIALS AND METHODS: The present cross-sectional observational study consists of three groups: Fifty patients with decompensated heart failure (Group 1) and same 50 patients after compensation (Group 2); 50 control patients group with comparable age and sex without heart failure (Group 3). Demographic, echocardiographic and biochemical data of patients were collected. Serum Cp level was determined spectrophotometrically. RESULTS: Serum ceruloplasmin was significantly increased in Groups 1 (820.8 ± 78.5 IU/dL) and 2 (873.5 ± 121.0 IU/dL) compared, to Group 3 (640.6 ± 132.4 IU/dL) (p<0.001). In the sub-group analysis, this difference was due to the difference between Groups 3, Group 1 and 2 (both p=0.0001) whereas no significant difference was present between Group I and Group 2 (p>0.063). A positive correlation was found between Cp and female sex, heart rate, systolic and diastolic blood pressure, acetylsalisilic acid and diuretic use, left ventricular systolic and diastolic diameter, mitral regurgitation, and negative correlation was found between Cp and ejection fraction (p<0.05 for all) whereas none of the parameters were independently associated with serum Cp level (p>0.05). CONCLUSIONS: Findings of the present study suggest that serum Cp level is increased in both decompensated and compensated HF compared to controls. Further large scale studies are needed to elucidate the pathophysiological mechanisms of increased Cp in HF.

RESUMO

PURPOSE: To evaluate signs of atherosclerosis in carotid and brachial arteries in patients with aortic regurgitation (AR). MATERIAL AND METHODS: The sonograms of 33 patients (24 M and 9 F, 16-67 years old) with pure AR and 20 control subjects (15 M and 5 F, 19-49 years old) were evaluated. Patients with AR and control subjects completed a questionnaire with SMART risk score based on pre-existing vascular disease and risk factors. AR patients and control subjects were assessed for intima-media thickness (IMT) of common carotid artery (CCA), IMT of brachial artery (BA), CCA diameter, and resistivity index (RI) of CCA and RI of internal carotid artery (ICA). RESULTS: There was no significant difference in the cardiovascular risk score between the patients with AR and control subjects. All measured parameters were statistically significantly greater in AR patients than in control subjects with P values 0.0233 for CCA IMT, 0.0034 for BA IMT, 0.0429 for CCA diameter, <0.0001 for CCA RI, and 0.0002 for ICA RI. CONCLUSION: AR is associated with signs generally considered to represent atherosclerosis, such as increased CCA and BA IMT, CCA diameter, and CCA and ICA RI.
