Background: Albuminuria, arterial stiffening and left ventricular hypertrophy (LVH) constitute target organ damage. We estimated whether increased urinary albumin excretion, assessed by albumin-to-creatine ratio (ACR), and carotid to femoral pulse wave velocity (c-f PWV) were accompanied by augmented left ventricular (LV) mass index (LVMI) in hypertension. Methods: In 428 non-diabetic untreated hypertensives (257 men, mean age = 52 years, office blood pressure (BP) = 146/93 mm Hg) the distributions of ACR and c-f PWV were split by the median (8 mg/g and 7.8 m/s, respectively). Results: Age, male sex, 24 h systolic BP, ACR and c-f PWV were the independent predictors of LVMI (R 2 = 0.478, p < 0.0001). Among patients with low ACR (n = 198), those with high c-f PWV (n = 84) compared to those with low c-f PWV (n = 114) were characterized by increased LVMI (by 8.9 g/m 2, p = 0.012) and prevalence of LVH (30 vs. 14%, p = 0.015). Similarly among patients with high ACR (n = 230), those with high c-f PWV (n = 123) compared to those with low c-f PWV (n = 107) exhibited heightened LVMI (by 13.6 g/m 2, p = 0.001). Conclusions: Increased ACR in conjunction with pronounced arterial stiffness is accompanied by augmented LV mass and higher LVH rates. Furthermore, the interrelationships between albuminuria, c-f PWV and LVMI suggest parallel target organ damage progression. Copyright © 2011 S. Karger AG, Basel. Source

Background Laparoscopic cholecystectomy is a challenging procedure in Patients with cirrhosis. This study aims to evaluate the safety and outcome of laparoscopic cholecystectomy in patients with cirrhosis and examines the value of model for end-stage liver disease (MELD) score and ChildPugh classification in predicting morbidity. Materials and methods From January 1995 to July 2008, 220 laparoscopic cholecystectomies were performed in cirrhotic, ChildPugh class A and B patients. Indications included symptomatic gallbladder disease and cholecystitis. MELD score ranged between 8 and 27. ChildPugh class and MELD score were preoperatively calculated and associated with postoperative results. Data regarding patients and surgical outcome were retrospectively analyzed. Results No deaths occurred. Postoperative morbidity occurred in 19% of the patients and included hemorrhage, wound complications, and intra-abdominal collections controlled conservatively. Intraoperative difficulty due to liver bed bleeding was experienced in 19 patients. Conversion to open cholecystectomy was necessary in 12 cases. Median operative time was 95 min. Median hospital stay was 4 days. Patients with preoperative MELD score above 13 showed a tendency for higher complication rate postoperatively. ChildPugh classification did not seem to predict morbidity effectively. Conclusion Laparoscopic cholecystectomy can be performed safely in selected patients with cirrhosis ChildPugh A and B and symptomatic cholelithiasis with acceptable morbidity. Some of its advantages are shorter operative time and reduced hospital stay. MELD score seems to predict morbidity more accurately than ChildPugh classification system.

Background: Significant evidence shows that elevated heart rate (HR) is an independent risk factor in patients with coronary artery disease (CAD) and influences their prognosis. In addition, patients with chronic obstructive pulmonary disease (COPD) have more frequent episodes of angina and their compliance with heart rate agents, such as beta blockers, is poor. The purpose of the multicenter observational RYTHMOS study was to evaluate the role of heart rate management in the prognosis and quality of life in patients with CAD and COPD. Methods: Baseline data from 280 patients, enrolled in 22 hospitals representing all types of hospital and all geographical areas of the country, were analyzed. All patients had either a prior myocardial infarction or angiographically documented CAD, and COPD verified either after spirometry or from a clinical evaluation by pulmonologists. Results: The mean age of the enrolled patients was 71.8 ± 9.3 years, 76% were males, mean body mass index was 28.6 ± 7.9 kg/m 2, 76.3% had hypertension, 31% had diabetes mellitus, and 53.5% of them suffered from heart failure. About 31% of the patients had an angina episode the week before the enrollment and the Canadian Cardiovascular Society (CSS) classification was class I, II, III and IV in 55%, 30%, 14% and 1%, respectively. The mean resting HR was 72.5 bpm; 51% of the patients had resting HR>70 bpm and 22% of them had HR≥80 bpm. Only 52.8% of the study patients were receiving beta-blockade (BB) therapy; they were more likely to have resting HR≤70 bpm (57.4% vs. 42.7%, p<0.001). 16.4% of the patients were receiving ivabradine and they had a higher initial HR compared to the others (78.5 vs. 71.3, p<0.001). Multivariate analysis showed that diabetes mellitus was independently associated with HR>70 bpm. Patients with resting HR>70 bpm had significantly more frequent angina episodes (p<0.001), were less satisfied with treatment (p<0.001), and had a lower quality of life (p<0.001). Conclusion: The baseline data of this study showed that patients with CAD and COPD present inadequate HR control and frequent angina episodes. Apart from the special characteristics of these patients related to COPD management, underuse of BB therapy largely contributes to the inadequate control of HR. Patients with HR>70 bpm had significantly worse quality of life. Source

Background and aim: Patients with genotype 4 (G4) chronic hepatitis C (CHC) are considered a difficult to treat population, although current data on G4 treatment responsiveness and duration are controversial. Greece represents a country with an intermediate prevalence of G4 infections, offering an opportunity to compare treatment outcomes by genotype and to identify potential prognostic factors for sustained virologic response (SVR). Methods: All CHC patients from the HepNet.Greece, an ongoing nationwide cohort study on viral hepatitis, with known hepatitis C virus (HCV) genotype who received treatment with Peg-IFNa and ribavirin were analyzed. Results: From 4443 patients, 951 (61.7% males, 78.4% Greeks, median age 40.6 years, 10% cirrhosis) fulfilled the inclusion criteria. G4 was found in 125 (13.1%) patients. Genotype distribution was not significantly different between Greeks and immigrants. Patients with G4 had similar odds of SVR compared to G1 but significantly lower compared to G2/G3. Age, treatment discontinuation, presence of cirrhosis and previous history of HCV-treatment were associated with lower probabilities of SVR. Ethnicity did not affect SVR for all genotypes while response to treatment was similar between Greek and Egyptian patients groups (35.7% vs 40.9%, p=0.660%) with G4 infection. The relation between SVR and genotype did not substantially change after adjustment for age, gender, cirrhosis, treatment interruption and history of HCV-treatment. Conclusions: The findings of this large cohort of CHC patients with a well balanced genotype distribution further supports the idea of considering G4 as a difficult to treat genotype. Further investigation is needed to identify genotype specific prognostic factors. Source

Background/objectives: Acute coronary syndromes (ACS) continue to pose a significant medical and socioeconomic burden worldwide. Optimal management strategy aims to improve short and long-term outcome. The present study aims to assess short-term outcome of real-world ACS patients and evaluate the achievement rate of secondary prevention goals. Methods: The TARGET study is an observational study enrolling 418 consecutive ACS patients from 17 centers countrywide (78.0% males, 63.9±12.9 years). After the in-hospital phase, patients were followed for 6 months. In total, 366 patients were included in the prospective phase of the study. At the end of the follow-up, mortality, major adverse cardiovascular events (MACE), prescription pattern of cardiovascular medications, lipid levels, adherence rate to treatment and behavioral recommendations were measured. Results: The overall mortality was 4.8% and the rate of MACE was 17.5%. At 6 months, a significantly lower proportion of patients received antiplatelet agents and statins as compared to hospital discharge. At the end of the follow-up, 87.7% of patients remained on statin treatment, yet only 18.2% of patients had LDL cholesterol levels less than 70 mg/dL. The adherence pattern to lifestyle and dietary recommendations remained low (66.2% quit smoking, 55.8% and 81.3% followed physical activity and dietary recommendations respectively). Conclusion: Despite the lowrate ofmortality andMACE occurrence rate in this countrywide observational study, the attainment rate of secondary prevention goals is relatively poor. Improvement interventions focusing in these gaps of optimal care provision are expected to have a favorable impact on the prognosis of real world ACS patients. © 2012 Elsevier Ireland Ltd.
