Objective: Vitamin D deficiency has been associated with cardiovascular disease. The aim of this study was to determine serum concentration of 25 hydroxyvitamin D (25(OH)D) in patients with acute coronary syndrome (ACS) and to assess the prognostic role of serum vitamin D level in ACS patients during 3-year follow up.Methods: The study included 60 ACS patients hospitalized at cardiology department for ACS between March 2012 and October 2012, and 60 age- and sex-matched control patients without ACS. Standard laboratory testing and vitamin D determination were performed in all study patients. In addition, ACS patients underwent coronarography and were followed-up for 36 months of ACS for major adverse cardiac events (MACE).Results: Patients with ACS had a statistically significantly lower mean 25(OH)D level as compared with control group (35.19 nmol/L vs. 58.08 nmol/L, p<0.001). The lowest mean level of 25(OH)D was recorded in diabetic patients with ACS (30.45 nmol/L). ACS patients were divided into three subgroups according to coronarography findings: single vessel, double vessel and triple vessel coronary artery disease (CAD) with respective serum levels of 25(OH)D of 36.44 nmol/L, 33.65 nmol/L and 31.70 nmol/L. During 36-month follow up, the event-free survival rate was 60% in the ACS group. The ACS patients having sustained MACE during follow up had low serum level of 25(OH)D in the acute phase; however, the difference from ACS patients without MACE during follow up did not reach statistical significance (32.64 nmol/L vs. 37.01 nmol/L).Conclusions: Patients with ACS have low vitamin D level, which is lowest in diabetic patients with ACS. However, during 3-year follow up, vitamin D failed to prove useful as a prognostic biomarker in ACS patients. [ABSTRACT FROM AUTHOR]

Introduction and goal: The latest 2011 non-ST-segment elevation acute coronary syndromes (NSTE-ACS) management guidelines indicated that all patients should receive anticoagulation drugs irrespective of the treatment strategy. In this report, 2-year data on anticoagulation therapies for NSTE-ACS are presented, in relation to invasive management selection and treatment outcomes in a clinical setting without registered bivalirudin. Patients and Methods: Data for 374 patients with NSTE- ACS treated in the Coronary Care Unit in General Hospital Slavonski Brod, Croatia were analyzed from January 2012 to December 2013. Treatment strategies, outcomes and complications among patients treated with different anticoagulation agents (enoxaparine, fondaparinux or unfractionated heparin) were analyzed and compared. Results: In all, 72% of all NSTE-ACS patients were treated invasively, out of which 66% underwent angiography within 72 hours. Urgent and early angiography was performed in 44% of all invasively treated patients. Generally, 58% and 5% of patients received enoxaparine and unfractionated heparin (UFH), respectively, whereas fondaparinux was administered in 37% of patients. Median age of patients treated with enoxaparine was 66, compared to 76 in the fondapari- nux group. There were significantly more patients treated with enoxaparine and UFH than with fondaparinux in the invasive strategy group. We observed that the number of patients treated with fondaparinux in the invasive group increased together with the period between symptom onset and angiography. The number of patients treated conservatively with either fondaparinux or enoxaparine was almost equal. There were no patients treated conservatively with UFH. In general, in-hospital mortality was low, 2.6% with no significant differences in bleeding events regarding the selection of anticoagulation therapy. Conclusions: Although the guidelines gave preference to fondaparinux, everyday practice in our hospital showed that enoxaparine was a preferred agent, particularly in younger patients selected for early invasive strategy, most probably because of the risk/benefit ratio and opportunity of avoiding the mixing of anticoagulation agents. Only 5% of patients were selected for urgent invasive approach with UFH, which should probably increase in the future. Considering a higher cost of bivalirudin, the introduction of this agent for non-ST segment elevation myocardial infarction management does not seem to be mandatory in our clinical setting, since this small group of patients was adequately managed with UFH.

Postpericardiotomy syndrome (PPS) is worsening or new formation of pericardial and/or pleural effusion mostly 1 to 6 weeks after cardiac surgery, as a result of autoimmune inflammatory reaction within pleural and pericardial space. Its incidence varies among different studies and registries (2% to 30%), as well as according to the type of cardiac surgery performed. We conducted this retrospective analysis of PPS incidence and diagnostic and treatment strategies in patients referred for cardiac surgery for revascularization, valvular and/or aortic surgery. We retrospectively analyzed 461 patients referred for an urgent or elective cardiac surgery procedure between 2009 and 2015. PPS diagnosis was established using well defined clinical criteria. Demographic and clinical characteristics were used in regression subanalysis among patients having undergone surgery of aortic valve and/or ascending aorta. Within 6 weeks after cardiac surgery, 47 (10.2%) patients had PPS. The median time from the procedure to PPS diagnosis was 14 days. The incidence of PPS was 26% after aortic valve and/or aorta surgery, and 7.9% and 8.3% after coronary bypass and mitral valve surgery, respectively. Among patients subjected to aortic valve and/or aortic surgery, regression analysis showed significant association of fever, C-reactive protein (CRP) elevation between 5 and 100 mg/L, urgent procedure and postoperative antibiotic use with PPS diagnosis, whereas younger age showed near-significant association. All patients had complete resolution of PPS, mostly after corticosteroid therapy, with only 2 cases of recurrent PPS that successfully resolved after colchicine therapy. Pleural drainage was indicated in 15 (32%) patients, whereas only one patient required pericardial drainage. In conclusion, PPS incidence in our retrospective analysis was similar to previous reports. Patients having undergone aortic valve and/or aortic surgery were most likely to develop PPS. The most relevant clinical criteria for diagnosis in these patients were fever, CRP elevation between 5 and 100 mg/L, and pericardial and/or pleural effusion formation or worsening 2 weeks after cardiac surgery.
