    <jats:title>Abstract</jats:title> <jats:p>Infective endocarditis is an endovascular microbial infection of cardiovascular structures, localized on valves, large intrathoracic vessels, ventricular and atrial endocardium and prosthetic materials. IE may present as an acute, subacute and chronic disease. The incidence of IE ranges from one country to another within 3-10 episodes/100.000 persons per years. The classification of IE according to the localization of the infection is: left-sided native valve IE, left-sided prosthetic valve IE (PVE), right-sided IE and device-related IE.</jats:p> <jats:p>Echocardiography plays a key role in each of the steps of assessment of IE: the diagnosis, risk stratification and follow-up of patients with infective endocarditis. The major echocardiographic criteria for IE are discovering vegetations, abscess, new valvular regurgitation and prosthesis dehiscence. According to the recent ESC recommendation for diagnosis and assessment of patients with IE, in all patients with clinical suspicion of IE, transthoracic echocardiography (TTE) is the first step of assessment. If we speak about patients with prosthetic endocarditis, then transoesophageal echocardiography (TEE) is recommended in case of poor quality of TTE and in majority of patients with positive TTE. If TTE examination is negative with low suspicion of IE, further follow-up has to be stopped. If TTE is negative but there is a high suspicion of IE, TEE has to be repeated in 7-10 days. Anatomical features on IE echocardiography have specific characteristics: vegetation, destructive valve lesion (perforation, prolapse of the valve) and abscess formation (more frequent in <jats:italic>Ao valve and in prosthetic valve</jats:italic>), which can be complicated with pseudoaneurysm and fistulization). Other cardiac imaging modalities (multislice computed tomogramphy (CT), magnetic resonance, 18F-fluorodesoxyglucose PET-CT, and single photon emission computed tomography (SPECT) /CT sometimes can be used in discovering complications in IE.</jats:p> <jats:p><jats:bold>Conclusion:</jats:bold> Echocardiography is useful in diagnosis of endocarditis, assessment of the severity of the disease, prediction of short-term and long-term prognosis, prediction of embolic risk, management of its complications, as well as deciding whether to operate or not and in choosing optimal time for surgery and follow-up.</jats:p>

    Late nephrology referral of patients with chronic kidney disease (CKD) has been suggested as increasing mortality after the initiation of dialysis. The aim of this study was to assess the impact of nephrology referral on the initiation of haemodyalisis (HD) and mortality during HD treatment in end-stage renal disease (ESRD) patients who have died in our institution over a five-year period. We studied data from all 117 patients on HD treatment in our institution who died (after 90 days of HD treatment) in the period between 01.01. 2002 and 31.12. 2006. Early (ER) and late referral (LR) were defined by the time of follow-up by a nephrologist greater than or less than 6 months, respectively, before the initiation of haemodialysis. Out of a total of 117 patients, 37.6% (44 patients) started HD in the ER group and 62.4% (73 patients) in the LR group. At the start of HD, LR patients were older, had a higher proportion of temporary catheters and had a significantly lower levels of haemoglobin and diuresis. Creatinine clearance was less in the LR (7.67 +/- 3.86 ml/min/1.73 m2) vs. the ER group (8.70 +/- 3.62 ml/min/1.73 m2), but not significantly different. Cardiovascular disease (CVD), defined by a history of myocardial infarction, cerebral vascular disease, peripheral arteriopathy, and/or heart failure, was also significantly more common among LR patients compared to ER (56%; 27%, p = 0.002). During the haemodyalisis treatment, the LR group had significantly lower levels of haemoglobin and haematocrit. CVD accounted for about 64% of deaths observed in the LR group. According to echocardiography data, there were no significant differences in the left ventricular mass index (LVMI) between the LR and ER groups at the time of dialysis initiation, but during haemodialysis treatment the LR group had significantly greater LVMI than the ER group (232,96 +/- 92,48 g/m2 vs.184,09 +/- 51,74 g/m2; p = 0,031). The time until death in months during dialysis treatment was significantly different between the LR and ER group, (69.51 +/- 64.03 vs.113.27 +/- 89.03, p = 0.0025). LR patients experienced a greater degree of anaemia and a high prevalence of CVD at the time of dialysis initiation. Our data suggest that the anaemia, CV damage and progression of left ventricular hypertrophy (LVH) in the LR patients during haemodialysis treatment are associated with poor survival on haemodialysis.

    Background: The aim was to evaluate the Nt-proBNP discriminatory role between symptomatic and asymptomatic patients with severe aortic stenosis. Methods: 187 patients with severe valvular aortic stenosis, with normal EF > 50%, were included, 61 asymptomatic and 126 symptomatic. We used clinical, laboratory (Nt-proBNP) and echocardiographic parameters. Endpoints of monitoring (occurrence of event) were: the onset of symptoms in asymptomatic patients and death in both groups. Results: The symptomatic group with severe AS had a significantly higher means of Nt-proBNP, in comparison with the asymptomatic group. Nt-proBNP was a significant predictor for the risk of event occurrence (HR 1.4). In the group of severe AS without CAD (n = 101), the subgroup with Nt-proBNP above the cut-off value, took significantly higher percentage of patients with chest pain, fatigue and syncope. In the group with Nt-proBNP above the cut-off value, we had a significantly higher percentage of patients with severe AS without CAD, compared to those with CAD (n = 142). Nt-proBNP was negatively correlated with AVA and LVEF, whether the positive correlation was expressed for: LVEDd, LVEDs, IVSd, AV_Vmax, AV_MaxGrad, LVM and LA. Patients with Nt-proBNP above the cut-off, had a significantly lower event free survival, compared to patients with Nt-proBNP below the cut-off (n = 187; n = 101). Conclusion: The Nt-proBNP cut-off> 460 pg/ml was confirmed as a useful tool in the determination of event free survival in patients with severe AS. Nt-proBNP not only had relevance in the assessment of the severity of the disease, but also was a significant predictor for the risk of event occurrence.

    These case reports aim to show that hyperfibrinogenemia is a risk factor for the progression and prognosis of peripheral arterial disease (PAD), in patients with and without diabetes mellitus type 2. We present a patient with PAD who has type 2 diabetes mellitus, who has previously been repeatedly treated for lower limb ischemia with multiple vascular surgeries performed. A few weeks before admission the patient developed critical lower limb ischemia, which was treated with an iliaco-popliteal and femorofemoral bypass. The patient had elevated serum fibrinogen values. In the current admission, renewed left limb ischemia was diagnosed, and surgically evaluated with a recommendation for amputation of the left limb as a surgical recommendation. Our second patient had a stable intermittent claudication, dyslipidemia and hyperfibrinogenemia. He was successfully treated for those risk factors. Regular monitoring of the patient showed improved claudication distance and quality of life Our case reports, supported by a literature review, demonstrate that hyperfibrinogenemia is a possible risk factor for progression and the prognosis of PAD.

    <jats:title>Abstract</jats:title> <jats:p><jats:bold>Introduction.</jats:bold> A transient ischemic attack (TIA) is an acute episode of temporary neurologic dysfunction that typically lasts less than an hour. Atherosclerotic plaques in the carotid arteries may cause TIA by lumen stenosis or plaque-related thromboembolism. The aim of this paper was to analyze the changes of the carotid arteries in patients with TIA and associated risk factors.</jats:p> <jats:p><jats:bold>Methods.</jats:bold> A retrospective analysis of 62 TIA patients was performed. Color duplex sonography of the carotid arteries and risk factor assessment was carried out in all patients.</jats:p> <jats:p><jats:bold>Results.</jats:bold> We analyzed 15(24%) females and 47(76%) males with TIA, aged 45-79 years. The most frequent risk factor was hypertension, present in 57 patients (91.9%). The most common findings of the extracranial segments of the carotid arteries were atheromatous plaques present in 25.8% and low-grade stenosis (40-59%) visualized in 24.1% of patients. Multiple plaques predominated, mostly localized in the region of bifurcation and the beginning of the internal carotid artery (67.7%), with irregular surface (in 58.1%), heterogenous structure (70.9%) and mostly hypoechogenic (46.8%).</jats:p> <jats:p><jats:bold>Conclusion.</jats:bold> These data have demonstrated a significant relationship between carotid artery ultrasound plaque characteristics and TIA occurrence. That is why color duplex sonography of the carotid arteries should be carried out in all TIA patients and risk factors should be evaluated, in order to take appropriate therapeutic measures for prevention of definitive stroke.</jats:p>

    Introduction.Post-transplant diabetes (PTDM), impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) are common complications of immunosuppressive therapy (IT) and are associated with increased cardiovascular morbidity and impaired graft function (GF). Methods. Fifty-nine living donor kidney transplant recipients (KTR) were included in a combined cross-sectional and 8-month-observational prospective study about the impact of impaired glucose homeostasis (IGH) on GF. All patients were on standard IT including cyclosporine A (CsA), steroids and mycophenolate mofetil (MMF). In all patients a standard oral glucose tolerans test (OGTT) was performed. Results were classified according to the criteria of the American Diabetes Association: normal-with fasting blood glucose level (FGL) <5.6, IFG with FGL of 5.6-6.9, IGT with FGL of 7.8-11.1 and DM between > 6.9 FGL and >11 mmol/l. According to the results, all patients were divaded into two groups: Group 1 with impaired and Group 2 with normal GH. GF was estimated by GFR-Cockroft Gault (CG) and by degree of proteinuria in the beginning and end of the study.</jats:p> <jats:p><jats:bold>Results.</jats:bold> Twenty of 59(33.9%) patients showed overt IGH after transplantation while the remaining 39(66.1) were normal. The principal dysglycemia in KTR were PTDM (2 patients-3.3%), IGT (18 patients-30.5%) and IFG (7 patients-11.8%). In Group 1, postprandial glucose was higher (8.1±2.3 vs 5.8±0.7), more KTR were male (70% vs 33.3%), higher CsA levels were observed (160.9±81.2 vs 115.1±59.9) and time after the surgery was shorter (24.5±21.3 vs 41.4±28.). After a follow-up period of approximately 18 months in Group 1 a significant decline in GFR (62.6-52.7 ml/min) was noted, with no significant change in proteinuria. The correlation analysis was positive between CsA level and IGH and the time after transplantation and IFG. Conclusion.</jats:bold> Post-transplant dysglycemia and associated metabolic abnormalities are a significant factor for the deterioration of GF. CsA higher levels are associated with the occurrence of IGH and they affect the GF.

    Objective: The aim of the study was to assess the prevalence of newly diagnosed diabetes in patients with acute coronary syndrome and estimate the relationship between stress hyperglycemia, glyco-regulation and newly diagnosed diabetes with hospital morbidity and mortality. Methods: This was an observational study which included all patients hospitalized due to acute coronary syndrome (January 2015 until April 2017) at the University Clinic of Cardiology in Skopje, Macedonia. We analyzed demographic, clinical, biochemical variables and hospital morbidity and mortality. Five investigated groups were compared using a single biochemical parameter glycated hemoglobin (HgbA1c) depending on the presence of known diabetes before the acute event: 0-without DM (HgbA1c <5.6%), 1-newly diagnosed pre-diabetes (HgbA1c 5.6-6.5%), 2-newly diagnosed diabetes (HgbA1c ≥ 6.5%), 3-known well controlled diabetes (HgbA1c <7%) and 4-known uncontrolled diabetes (HgbA1c ≥7%). Results: 860 patients were analyzed. Impaired glucose metabolism was confirmed in 35% of patients, 9% of which were with newly diagnosed diabetes. Stress hyperglycemia was reported in 27.3% (3.6% were without diabetes). The highest values of stress hyperglycemia were reported in newly diagnosed and known uncontrolled diabetes. In-hospital morbidity and mortality were 15% and 5% accordingly and the rate was highest in patients with newly diagnosed and known, but un-controlled diabetes. HgbA1c, stress hyperglycemia, and poor glycemic control have emerged as significant independent predictors of hospital morbidity and mortality in patients with acute coronary syndrome. Conclusion: High prevalence of newly diagnosed diabetes was observed in patients with acute coronary syndrome. Stress hyperglycemia and failure to achieve glycemic control are independent predictors of hospital morbidity and mortality.
