RESUMO
INTRODUCTION: Atrial fibrillation represents the most common cardiac arrhythmia in clinical practice. By year 2030, 14-17 million AF patients are anticipated in the European Union. Atrial fibrillation remains one of the major causes of stroke, heart failure, sudden death all over the world. RESEARCH OBJECTIVES: The objective of our study is to determine the cardiac and cerebrovascular events (myocardial infarction, heart failure, stroke, sudden cardiac death) and their cumulative incidence during 11 years follow up period. PATIENTS AND METHODS: This study includes 2352 ambulant and hospitalized patients with atrial fibrillation (AF) who were enrolled during the follow up period. All patients underwent clinical evaluation in order to determine cardiac and cerebrovascular events (myocardial infarction, heart failure, stroke, sudden cardiac death) and their cumulative incidence. RESULTS: The results of cumulative incidence for sudden cardiac death was 1.71%, for stroke 2.56%, for myocardial infarction 1.20% and for heart failure was 5.73%. In our study the age-adjusted incidence and prevalence of AF are slightly lower in women. The study shows that the risk of death is higher in females than in males with AF. CONCLUSION: Despite good progress in the management of patients with atrial fibrillation (AF), this arrhythmia remains one of the major causes of stroke, heart failure, sudden death. Effective treatment of patients with atrial fibrillation includes not only rate control, rhythm control, and prevention of stroke, but also management of cardiovascular risk factors and concomitant diseases.

Being a narrow therapeutic index drug, digoxin may cause harm if dosed without regular measurements of serum levels. Due to various limitations in its dosing, different challenges still exist in clinical practice. This study aimed to assess digoxin though concentrations after different regimens in adult and elderly patients, and to identify predictor variables for the ratio of given dose and digoxin trough level. This was prospective open-label study. Digoxin was administered per os as 0.125 or 0.25 mg during different continuous and interrupted dosage regimens. Study protocol allowed an additional therapy according to contemporary guidelines. Digoxin concentrations were determined using Abbott AxSYM Digoxin II assay in trough samples (1-3 per patient) after 3-4 weeks stable regimen. In total, 191 concentrations (104 patients) were analyzed. Digoxin weekly dose was in range 0.375-1.75 mg. On average, we observed slightly lower digoxin levels in HF patients. Results showed that in patients receiving digoxin with interrupted dosage regimen post- pause digoxin level was statistically significantly lower than pre-pause (p < 0.05). Based on multi- ple linear regression, the ratio of given dose and trough concentration was mainly predicted by clearance creatinine, and to lesser extent by patient's ideal body weight. Interrupted dosing schedule shows greater variability in drug levels comparing to continuous dosing, and it additionally causes difficulties in reaching and maintaining steady trough levels between doses. Hence, individualization of dosing regimen should be carefully guided based on target levels and not solely on clinical signs and symptoms.

INTRODUCTION: The term masked hypertension (MH) should be used for untreated individuals who have normal office blood pressure but elevated ambulatory blood pressure. For treated patients, this condition should be termed masked uncontrolled hypertension (MUCH). RESEARCH OBJECTIVES: Masked uncontrolled hypertension (MUCH) has gone unrecognized because few studies have used 24-h ABPM to determine the prevalence of suboptimal BP control in seemingly well-treated patients, and there are few such studies in large cohorts of treated patients attending usual clinical practice. This is important because masked hypertension is associated with a high risk of cardiovascular events. This study was conducted to obtain more information about the association between hypertension and other CV risk factors, about office and ambulatory blood pressure (BP) control as well as on cardiovascular (CV) risk profile in treated hypertensive patients, also to define the prevalence and characteristics of masked uncontrolled hypertension (MUCH) among treated hypertensive patients in routine clinical practice. PATIENTS AND METHODS: In this study 2514 male and female patients were included during a period of 5 years follow up. All patients have ambulatory blood pressure monitoring (ABPM) for at least 24h. We identified patients with treated and controlled BP according to current international guidelines (clinic BP, 140/90mmHg). Cardiovascular risk assessment was based on personal history, clinic BP values, as well as target organ damage evaluation. Masked uncontrolled hypertension (MUCH) was diagnosed in these patients if despite controlled clinic BP, the mean 24-h ABPM average remained elevated (24-h systolic BP ≥130mmHg and/or 24-h diastolic BP ≥80mmHg). RESULTS: Patients had a mean age of 60.2+10 years, and the majority of them (94.6%) were followed by specialist physicians. Average clinic BP was 150.4+16/89.9+12 mmHg. About 70% of patients displayed a very high-risk profile. Ambulatory blood pressure monitoring (ABPM) was performed in all recruited patients for at least 24h. Despite the combined medical treatment (78% of the patients), clinic control (<140/90 mmHg) was achieved in only 26.2% of patients, the corresponding control rate for ambulatory BP (<130/80 mmHg) being 32.7%. From 2514 patients with treated BP, we identified 803 with treated and controlled office BP control (<140/90 mmHg), of whom 258 patients (32.1%) had MUCH according to 24-h ABPM criteria (mean age 57.2 years, 54.7% men). The prevalence of MUCH was slightly higher in males, patients with borderline clinic and office BP (130-139/80-89 mmHg), and patients at high cardiovascular risk (smokers, diabetes, obesity). Masked uncontrolled hypertension (MUCH) was most often due to poor control of nocturnal BP, with the proportion of patients in whom MUCH was solely attributable to an elevated nocturnal BP almost double that solely attributable to daytime BP elevation (22.3 vs. 10.1%, P 0.001). CONCLUSION: The prevalence of masked suboptimal BP control in patients with treated and well-controlled clinic BP is high. The characteristics of patients with MUCH (male, longer duration of hypertension, obesity, smoking history, and diabetes) indicate that this is a higher-risk group with most to gain from improved BP.

OBJECTIVE: Our objective was the comparison of combined utility of two-dimensional (2D) transthoracic echocardiography (TTE) and three-dimensional (3D) TTE versus 2D and 3D transesophageal echocardiography (TEE) in evaluation of anatomy of the left atrium appendage (LAA) and for clot formation in LAA. BACKGROUND: 2DTEE as semi-invasive method has been for a long time used to visualize the LAA. Improved echocardiography technology has increasingly improved visualization of LAA by 2DTTE and 3DTTE in many patients and decreased the need for TEE performance. METHODS: We compared combined 2DTTE and 3DTTE with 2DTEE and 3DTEE in evaluating the LAA for anatomical features and thrombus. Eighty-six patients underwent 2DTTE, 3DTTE, 2DTEE and 3DTEE. RESULTS: LAA could be visualized in all patients. 31 % of patients had one lobe, 43% had 2 lobes and 26% had > 2 lobes. Of 86 patients studied, 79 had no thrombus and 7 had thrombus in the LAA by all modalities. Six patients, 3 with atrial fibrillation (AF), and 4 in sinus rhythm (SR) had a suspected thrombus by 2DTEE. Only in one patient 3DTEE cropping has been needed to clearly show thrombus which was suspected in short axis view on 2DTEE as rounded echo dense mass. CONCLUSIONS: Our preliminary study suggests that combined 2DTTE and 3DTTE has comparable accuracy to TEE in evaluating the LAA anatomy and pathology in terms of thrombus. Only in inappropriate (obese) patients 2TTE, but not 3DTTE, may misdiagnose pectinate musculature as thrombus.

INTRODUCTION: Usage of fibrinolytic therapy leads to reperfusion of the occluded coronary arteries, rescue of ventricle myocardium and successful recovery of patient. GOAL: The objective of this study was to compare the reperfusion effect of streptokinase and alteplase in acute myocardial infarction (AMI) by analyzing echocardiographic parameters and post-coronarography treatment. PATIENTS AND METHODS: We observed 53 patients in AMI and divided them depending on applied therapy in streptokinase and alteplase group. Both groups were further divided into three subgroups depending on the time passed from chest pain occurrence to admission at Clinic. Observed echocardiographic parameters were: mitral regurgitation, left ventricular systolic and diastolic function and signs of ischemic cardiomyopathy. On coronary angiogram we analyzed severity of coronary artery disease as well as recommended treatment thereafter. RESULTS: There were no significant difference in post-coronarography treatment, incidence and severity of mitral regurgitation and ischemic cardiomyopathy in alteplase vs streptokinase group- only significantly less diastolic dysfunction was noted in alteplase group (p=0.037). We noticed only significant difference when we took into consideration time from chest pain to admission at clinic. In alteplase first subgroup were more patients treated only with medications (without need for revascularization) vs streptokinase first subgroup (62,5% vs 28.6%, p=0.047). In alteplase first subgroup was lower incidence of mitral regurgitation (p =0.045), developed cardiomyopathy (p =0.009) and more preserved left ventricular diastolic function (p =0.008) compared to first streptokinase subgroup. CONCLUSION: In our study we have found a significant difference between streptokinase and alteplase in echocardiographic parameters and post-coronarography treatment when we took into consideration time from occurrence of chest pain to admission at Clinic. The best outcomes had patients who were treated with alteplase within 1.5 hour from occurrence of chest pain.

OBJECTIVE: To assess serum levels of tumor marker carbohydrate antigen 125 (CA125) in patients with heart failure (HF) and to investigate possible correlation with echocardiographic parameters and level of brain natriuretic peptide (BNP). PATIENTS AND METHODS: We included 76 patients with different cardiac symptoms hospitalized at Clinic for heart disease and rheumatism. Control group (n = 26) was consisted of patients without signs and symptoms of HF, normal left ventricle ejection fraction (LVEF) and normal BNP level. Patients with diagnosis of HF (n = 50) were subdivided into 2 group depending on signs and symptoms of fluid overload: compensated (compHF, n = 10) and decompensated group (decompHF, n = 40). Serum CA125 and BNP were measured on admission and all patient underwent ECG recording and trans thoracic echocardiographic examination. RESULTS: The median CA125 level in HF group was significantly higher compared to control group (71.05 [30.70-141.47]U/ml vs 10.75 [8.05- 14.32] U/ml, p < 0.0005). Higher CA125 levels were found in decompHF group compared to compHF group (94.90 [49.75-196.75]U/ml vs 11.90 [10.25-15.80]U/ml, p < 0.0005). In decompHF group 13 of patients had pleural and/or pericardial effusion- their CA125 levels were significantly higher compared to patients without serosal effusion (n = 27) (205.10 [106.50-383.90]U/ml vs. 71.50 [47.30-109.55] U/ml, p < 0.002). We found significant difference in CA125 levels between patients with atrial fibrillation and sinus rhythm (98.40 [48.20-242.70] U/ml vs. 47.30 [12.95-99.05] U/ml, p = 0.015). There was no significant difference in CA125 levels in group with enlarged left atrium compared to normal sized atrium (p = 0.282), as well as in group with moderate/severe mitral regurgitation compared to group with no/mild mitral regurgitation (p = 0.99). Finally, levels of serum CA125 positively correlated with serum level of BNP (r = 0.293, p = 0.039), but not with LVEF (p = 0.369) and left atrium diameter (p = 0.636). CONCLUSION: Serum CA125 is elevated in decompensated HF patients: more pronounced elevation was found in patients with pleural and/or pericard effusion compared to patients with no serosal effusion. CA125 level correlated with BNP, but not with left atrium diameter nor with LVEF. Tumor marker CA125 could be used as a marker of systemic congestion and volume overload in decompensated HF. We hypothesized that high CA125 level indicates that measured high BNP is actually wet BNP.

Coronary artery spasm is one of the well-known causes of anginal chest pain. We presented the case of prolonged spasm of the left anterior descending coronary artery which happened during coronary angiography leading to pulse less state and low blood pressure with syncope and appearing of ventricular fibrillation on ECG. During one hour of successful cardiopulmonary resuscitation, the patient had again normal pulse and blood pressure. Coronary angiography performed immediately after DC's showed normal coronary angiogram. After two days the patient left the hospital without brain disorders.

As patients and their physicians become more demanding, the desire to make the procedures "minimally invasive" is growing constantly. In short, "minimally invasive" is a code phrase for life saving procedures which in same time disrupt our quality of life the least. Its goals include reducing incision size, decreasing surgical trauma and pain, and improving cosmesits, patient satisfaction, and recovery times. However, the most important goal of minimally invasive aortic valve surgery must be to maintain or improve the efficacy and safety of conventional aortic valve surgery. In this report we would like to present operative technique of minimally invasive aortic valve replacement (MIAVR) we use in our hospital.

Background: The prevalence of chronic heart failure (CHF) is up to 1-2% of the adult population in developed countries, rising to >10% after the age of 70. Heart failure with reduced ejection fraction (HFrEF) remains a prevalent clinical syndrome associated with significant morbidity and mortality. Objective: The aim of this study was to evaluate the clinical efficacy of sacubitril/valsartan in a group of ambulatory patients with heart failure with reduced ejection fraction (HFrEF) and its effect on the hemodynamic, metabolic, renal, and cardiac remodeling parameters. Methods: From January 2018 to May 2021, 106 patients with chronic heart failure with reduced ejection fraction (HFrEF) were prospectively enrolled. Patients treated with sacubitril/valsartan (ARNI) were compared with an arm of the same size (n = 53) and matched by age and gender who were taking a standard optimal medical therapy for HFrEF. Results: The 106 patients completing the study were characterized by age: 69.5 ± 8.0, 64% are male gender. The mean duration of follow-up in the 2 treatment arms was 12 months. In the ARNI arm, we evaluate the hemodynamic, metabolic, renal, and cardiac remodeling parameters upon the initial evaluation and at the end of the follow-up after 12 months treatment with sacubitril/valsartan. The LVEF values increased significantly (p < 0.001) in the ARNI arm compared to the OMT arm, 42.1 % vs. 30.1%. The LVMI decreased from a baseline value of 153.1 g/m2 to 147.8 g/m2 with significant improvement only in the arm treated with ARNI. The eGFR values increased significantly (p < 0.001) in the ARNI arm compared to the OMT arm 70.1 vs. 64.9 mL/min/1.73 m2. Initiation and titration of sacubitril-valsartan was associated with a reduction in NT-pro-BNP concentration, the values of NT-pro-BNP improved significantly only in the arm treated with ARNI 3107.1 vs. 5678.2. Mortality and re-hospitalization due to HF were lower in the arm treated with ARNI compared to the control (20.3 vs. 32.4 % and 25.3 vs. 46.6 %, respectively; p < 0.05). Conclusion: Sacubitril/valsartan is an important advancement in the treatment of HFrEF. Sacubitril/valsartan induce "hemodynamic recovery". This study provides real-world data demonstrating incremental improvements in functional and echocardiographic outcomes in optimally treated patients with HFrEF switched to sacubitril/valsartan in ambulatory setting.

This study evaluated brain natriuretic peptide (BNP) release in acute myocardial infarction (AMI), absolute values as well as pattern of its release. There are two different patterns of BNP release in AMI; monophasic pattern--concentration in the first measurement is higher than in the second one, and biphasic pattern--concentration in the first measurement is lower than in the second one. We observed significance of biphasic and monophasic pattern of BNP release related to diagnostic and prognostic value. We included in this prospective observational study total of 75 AMI patients, 52 males and 23 females, average age of 62.3 +/- 10.9 years with range of 42 to 79 years. BNP was measured and pattern of its release was evaluated. In AMI group BNP levels were significantly higher than in controls (462.88 pg/mL vs. 35.36 pg/mL, p < 0.001). We found statistically significant real negative correlation (p < 0.05) between BNP concentration and left ventricle ejection fraction (LVEF) with high correlation coefficient (r = -0.684). BNP concentrations were significantly higher among patients in Killip class II and III compared to Killip class I; Killip class I BNP = 226.18 pg/mL vs. Killip class II 622.51 pg/mL vs. Killip class III 1530.28 pg/mL, p < 0.001. BNP concentrations were significantly higher in patients with; (i) myocardial infarction vs. controls; (BNP 835.80 pg/mL vs. 243.03 pg/mL); (ii) in pts with positive major adverse cardiac events (MACE) vs. negative MACE (BNP 779.08 pg/mL vs. 242.28 pg/mL, p < 0.001); (iii) in pts with positive compared to negative left ventricle (LV) remodelling (BNP 840.77 pg/mL vs. 341.41 pg/mL, p < 0.001). Group with biphasic pattern of BNP release had significantly higher BNP concentration compared to monophasic pattern group. In biphasic pattern group we found significant presence of lower LVEF, Killip class II and III, LV remodelling and MACE. We found that BNP is strong marker of adverse cardiac events in patients presenting with a myocardial infarction. In our AMI group we found significant elevation of BNP and it is suspected that second peak secretion is not only due to systolic dysfunction and subsequent remodeling of LV but also due to impact of ischaemia. Patients with biphasic pattern probably have worse prognosis due to severe coronary heart disease. Besides its diagnostic role as a simple blood marker of systolic function, BNP is also important prognostic marker who helps making clinical decision about early invasive vs. conservative management.

Angina pectoris may be associated with normaln coronary arteries. Normal coronary arteries status is defined as absence of visible disease or the irregularity of lumen (less than 50%) as assessed visually on the interventional cardiologists. In our retrospective study among 1130 patients we have identified 181 patients with normal angiographic findings with various risk factors, as male sex, body mass index (BMI), lipid disorders, smoking, hypertension, diabetes mellitus type 2. The analysis results suggest that 56.3% patients of 181 verified normal coronary findings involve female patients with high BMI, unregulated hypertension and lipid disorders. In order to find real causes of chest pain, patients with normal coronary status need careful examination and treatment. The reduction of risk factors and adequate medications are important preconditions for the good quality of life in these patients.

Dietary interventions with protein and salt restriction, good glucose control, smoking cessation, aggressive blood pressure control, good control of cholesterol and triglycerides, use of ACE inhibitors and ARBs can delay the progression of diabetic nephropathy. The aim of this study was to present the effects of aggressive treatment of the multiple risk factors for diabetic nephropathy on proteinuria in patients with type 2 diabetes. In this study we included 15 patients with diabetes type 2 and insufficient regulation of glycaemia. The patients were followed for three months period. Glycated haemoglobin (HbA1c), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), blood pressure, cholesterol and triglycerides and proteinuria were followed prior and after the study. Prior the study patients were treated with premix insulin divided in two daily doses + metformin after the lunch and they had insufficient regulation of glycaemia. During the study patients were treated with one daily dose of basal insulin, three doses of metformin (2550 mg), one daily dose of atorvastatin (20 mg) and one daily dose of ramipril (5 to 10 mg). Doses of insulin were titrated separately for each patients (0,7-1,0 IU/kg). Patients were advised to start with lifestyle modification, increased physical activity and dietary interventions with protein and salt restriction, energy restricted diet and smoking cessation. A total of 20 patients (male 12 and female 8) with diabetes type 2 were studied. The mean age of the subjects was 53+/-5,25 years. The mean diabetes duration was 4,05+/-1,96 years. The mean body mass index decreased from 28,1+/-1,67 kg/m2 to 25,9 +/-1,22 kg/m2 after the study. Mean HbA1c decreased from 8,82 +/- 0,53 % to 7,15 +/- 0,23 % (p<0,05). Mean fasting glycemia decreased from 8,79+/-0,58 mmol/dm3 to 7,03+/-0,18 mmol/dm3 (p < 0,05). Mean postmeal glycemia decreased from 9,93 +/- 0,77 mmol/dm3 to 7,62 +/- 0,42 mmol/dm3 (p<0,05). The mean cholesterol level decreased from 7,99 +/-0,64 mmol/dm3 to 5,93 +/- 0,65 mmol/dm3 (p<0,05). The mean triglicerides level decreased from 4,05 +/- 0,97 mmol/dm3 to 1,96 +/- 0,24 mmol/dm3 (p<0,05). The significant decrease of proteinuria was recorded, prior the study the mean albuminuria was 1,05 +/- 0,31 g/dm3 and after the study was 0,07 +/- 0,145 g/dm3 (p<0,05). Mean blood pressure prior the study was 153+/-8,69/91,5 +/- 3,78 mm Hg (p<0,05), after the study was 125 +/- 6,32/ 79,25+/-3,26 mmHg. Effective control of glycaemia, blood pressure, cholesterol and triglycerides, use of ACE inhibitors, dietary interventions with protein and salt restriction, smoking cessation, can delay the progression of nephropathy in type 2 diabetes.

UNLABELLED: We aimed to determine whether the administration of statins to type 2 diabetics without pre-existing CHD reduced the incidence of CHD and their effects on cholesterol and CRP levels. All the participants were carefully interviewed, clinically examined, and laboratory tested to exclude conditions likely to provoke an inflammatory response that was an exclusion criterion. EXCLUSION CRITERIA: Serious heart, liver or kidney problems, history of renal transplant, recent history of drug or alcohol abuse, HbA1c>10%, blood pressure >140/90 mmHg, BMI >35 kg/m2, triglycerides >3,0 mmol/dm3. 95 obese diabetics (mean age 60,9 years and BMI=31,59 kg/m2, diabetes duration more than 10 years) without pre-existing CHD, were included in the analysis and were randomized to simvastatin (25 female and 20 male used 40 mg simvastatin daily) or placebo (30 female and 20 male) group. After six months, simvastatin significantly lowered CRP levels by 19%, (p<0,01), cholesterol levels by 18%, TG levels by 8%, LDL levels by 20% and VLDL levels by 17%, whereas there was no change with placebo. After one year the difference sustained between groups. Coronary events were rarely in the simvastatin group (6,6%) than in the placebo group (14%). Coronary revascularizations were 4 in the placebo group and 1 in the simvastatin group. Rate of stroke was more often in the placebo group (18%) than in the simvastatin group (8,8%). So, reduction of acute CHD events is for 7,4% in the simvastatin group. Positive correlation was between CRP and CVD (r=0,29). Statin therapy reduced the risk of coronary heart disease in diabetics without CHD.

INTRODUCTION: Atrial fibrillation (AF) is the most common form of cardiac arrhythmia in clinical practice and its prevalence increases with age. Patients who develop AF also have cardiovascular risk factors, structural heart disease, and comorbidities, all of which can increase mortality. AF causes a significant economic burden with the increasing trend in AF prevalence and hospitalizations. RESEARCH OBJECTIVES: The objective of our study is to evaluate the impact of the most common known risk factors on the incidence of atrial fibrillation as an important precursor of cardiac and cerebrovascular morbidity and mortality among our patients in Bosnia and Herzegovina during median follow up period (September 2006 - September 2016). The other objective is to estimate the CHA2DS2-VASc score among our patients based on clinical parameters. PATIENTS AND METHODS: This study includes 2352 ambulant and hospitalized patients with atrial fibrillation. All patients underwent clinical evaluation which includes thorough assessment for potential risk factors and concomitant conditions in order to determine which of them represent the most common among examinees with atrial fibrillation. RESULTS: The results show that male gender has slightly more incidence of AF. Obesity and overweight with BMI ≥ 27, cigarettes smoking and sedentary life style are almost present in patients with AF. Arterial hypertension, coronary artery disease, diabetes mellitus, chronic obstructive pulmonary disease, chronic renal dysfunction, structural and valvular heart disease and peripheral vascular disease are the most common comorbidities among our patients. The mean CHA2DS2-VASc score was 3.2±1.4 and the mean HAS-BLED score was 2.1±1.2. CONCLUSION: Atrial fibrillation is the most common sustained cardiac rhythm disorder. The study shows that obesity, alcohol consumption, smoking cigarettes and dyslipidemia can be considered as triggers and predisposing factors for appearance of AF. Arterial hypertension, coronary artery disease, chronic obstructive pulmonary disease, diabetes mellitus, Peripheral vascular disease and chronic kidney disease are playing important role in developing of AF.

INTRODUCTION: The commonest mitral regurgitation etiologies are degenerative (60%), rheumatic post-inflammatory, 12%) and functional (25%). Due to the large number of patients with acute MI, the incidence of ischaemic MR is also high. Ischaemic mitral regurgitation is a complex multifactorial disease that involves left ventricular geometry, the mitral annulus, and the valvular/subvalvular apparatus. Ischaemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. RESEARCH OBJECTIVES: The objective of this study is to determine the role of echocardiography in detecting and assessment of mitral regurgitation mechanism, severity, impact on treatment strategy and long term outcome in patients with myocardial infarction during the follow up period of 5 years. Also one of objectives to determine if the absence or presence of ischaemic MR is associated with increased morbidity and mortality in patients with myocardial infarction. PATIENTS AND METHODS: The study covered 138 adult patients. All patients were subjected to echocardiography evaluation after acute myocardial infarction during the period of follow up for 5 years. The patients were examined on an ultrasound machine Philips iE 33 xMatrix, Philips HD 11 XE, and GE Vivid 7 equipped with all cardiologic probes for adults and multi-plan TEE probes. We evaluated mechanisms and severity of mitral regurgitation which includes the regurgitant volume (RV), effective regurgitant orifice area (EROA), the regurgitant fraction (RF), Jet/LA area, also we measured the of vena contracta width (VC width cm) for assessment of IMR severity, papillary muscles anatomy and displacement, LV systolic function ± dilation, LV regional wall motion abnormality WMA, LV WMI, Left ventricle LV remodeling, impact on treatment strategy and long term mortality. RESULTS: We analyzed and follow up 138 patients with previous (>16 days) Q-wave myocardial infarction by ECG who underwent TTE and TEE echocardiography for detection and assessment of ischaemic mitral regurgitation (IMR) with baseline age (62 ± 9), ejection fraction (EF 41±12%), the regurgitant volume (RV) were 42±21 mL/beat, and effective regurgitant orifice area (EROA) 20±16 mm(2), the regurgitant fraction (RF) were 48±10%, Jet/LA area 47±12%. Also we measured the of vena contracta width (VC width cm) 0,4±0,6 for assessment of IMR severity. During 5 years follow up, total mortality for patients with moderate/severe IMR-grade II-IV (54.2±1.8%) were higher than for those with mild IMR-grade I (30.4±2.9%) (P<0.05), the total mortality for patients with EROA ≥20 mm(2)(54±1.9%) were higher than for those with EROA <20 mm(2)(27.2±2.7%) (P<0.05), and the total mortality for patients with RVol ≥30 mL (56.8±1.7%) were higher than for those with RVol<30ml (29.4±2.9%) (P<0.05). After assessment of IMR and during follow up period 64 patients (46%) underwent CABG alone or combined CABG with mitral valve repair or replacement. In this study, the procedure of concomitant down-sized ring annuloplasty at the time if CABG surgery has a failure rate around 24% in terms of high late recurrence rate of IMR during the follow period especially after 18-42 months. CONCLUSION: The presence of ischaemic MR is associated with increased morbidity and mortality. Chronic IMR, an independent predictor of mortality with a reported survival of 40-60% at 5 years. Ischaemic mitral regurgitation has important prognosis implications in patients with coronary heart disease. Recognizing the mechanism of valve incompetence is an essential point for the surgical planning and for a good result of the mitral repair. It is important that echocardiographers understand the complex nature of the condition. Despite remarkable progress in reparative surgery, further investigation is still necessary to find the best approach to treat ischaemic mitral regurgitation.
RESUMO
AIM: To assess serum levels and correlation between uric acid (UA) and C-reactive protein (CRP) in acute coronary syndrome (ACS) and apparently healthy individuals. METHODS: The cross-sectional study included 116 examinees of age 44 to 83 years, distributed in two groups: 80 ACS patients including 40 with acute myocardial infarction (AMI), and 40 with unstable angina pectoris (UAP), and 36 apparently healthy (control group) individuals. Patients with ACS were hospitalized at the Cardiology Clinic, Clinical Centre Sarajevo in the period October- December 2012. Laboratory analyses were conducted by standard methods. The accepted statistical significance level was p<0.05. RESULTS: Serum levels of CRP and UA were higher in patients with ACS as compared to control group (p<0.01). The median serum UA was insignificantly lower, and CRP was significantly higher in patients with AMI compared to UAP (p=0.118 and p=0.001, respectively). CRP and UA correlated positively in both ACS and control groups (rho=0.246; p=0.028 and rho=0.374; p=0.027). A positive correlation between serum CRP and UA was noted in patients with AMI, but negative in patients with UAP (p>0.05). CONCLUSION: The correlation between CRP and UA in the patients with ACS indicates the association of oxidative stress and inflammation intensity in damaged cardiomyocytes. Correlation between UA and CRP in apparently healthy individuals indicates a possible role of UA as a marker of low-grade inflammation and its potential in risk assessment in cardiovascular diseases.

Brain natriuretic peptide (BNP) is released from ventricular myocites due to their stretching and volume overload. In heart failure there is BNP release. Aim of this study was to observe BNP release in acute myocardial infarction (AMI). We measured BNP in 75 patients with AMI. Control group (n=61) was similar by age and gender to AMI group. We found statistically significant elevation of BNP compared to controls (462.875 pg/ml vs 35.356 pg/ml, p< 0.001). Patients with severe systolic dysfunction had the highest BNP levels, while patients with the preserved systolic function had the lowest BNP levels (Group with EF< 30% BNP= 1129.036 pg/ml vs Group with EF31-40 % BNP= 690.177 pg/ml vs Group with EF 41-50% BNP= 274.396 pg/ml vs Group with EF> 51% BNP= 189.566 pg/ml, p< 0.001). We found statistically significant light positive correlation between BNP and left ventricle end-diastolic diameter (LVDd) (r= 0.246, p<0.05). and real positive correlation between BNP and peak troponin levels (r= 0.441, p < 0.05). BNP levels were higher in anteroseptal allocation of AMI compared to inferior allocation (835.80 pg/ml vs 243.03 pg/ml, p< 0.001) and in patients who were treated with heparin compared to fibrinolitic therapy (507.885 pg/ml vs 354.73 pg/ml, p< 0.05). BNP is elevated in AMI and is a quantitative biochemical marker related to the extent of infarction and the left ventricle systolic dysfunction. Besides echocardiographic calculation, elevation of BNP could be used for quick and easy determination of the left ventricle systolic dysfunction.

Potential risk of sudden death during sports participation makes screening of competitive athletes of vital importance. Congenital cardiac anomalies and non-atherosclerotic, acquired myocardial conditions are primary causes underlying exercise-induced cardiac death in young patients. Since cardiovascular conditions are the leading causes of non-traumatic, exercise-induced cardiac events, cardiovascular screening preceding sports participation in mandatory. The objectives of this study were to determine prevalence of cardiac conditions through cardiovascular screening of young athletes and to establish preventive strategy. The study was conducted at the Sports Medicine Center of Sarajevo Canton and at the Pediatric Clinic of University of Sarajevo Clinics Centre in the period 2007-2009. The study was supported by Canton Sarajevo Ministry of Health and Ministry of sports, science and culture. The study targeted a group of 214 athletes, 8-18 years of age with average age being 15.26. The group was subdivided into five groups according to the age. After taking the anamnesis (family, personal and cardiological) patients were subjected to the measuring of body mass and height, blood pressure and heart rate and oxygen saturation, recording of 12-lead ECG, specialist examination (pediatrician, sports medicine specialist and cardiologist) and complete heart echocardiography. No examined athletes expressed subjective discomfort. Congenital cardiac anomalies were not diagnosed in any athlete. Also, cardiovascular abnormalities requiring additional evaluation, positive cardiac anamnesis, abnormal auscultatory findings, hypertension or abnormal ECG findings were not recognized in any patient. Moderate correlation was found among the left ventricle mass and heart rate (p<0.05). In order to minimalize or even possibly prevent the risk of sudden cardiac death it is necessary to establish an adequate strategy of cardiovascular screening of young athletes.

PURPOSE: Cerebrovascular events (CVE) are the third most common cause of death in Western countries and about 65-70% of CVE are due to atherosclerotic disease of carotid arteries. Color Doppler scanning is used to evaluate the presence, severity and type of atheromatous plaques as well as velocity parameters of carotid arteries. We performed this study to correlate data of morphological and velocity parameters with clinical variables in patients following CVE. METHODS: We included total of 211 pts who had CVE, 118 females, 93 males, mean age 71.1 +/- SD 12.5 years. Out of total number of pts (n = 211) 93 pts had transient ischemic attacks (TIAs), 49 had recurrent TIAs (rTIAs), 44 had ischemic stroke (IS), and 25 had recurrent IS (rIS). As a control group we took 50 pts without CVE but with at least three multiple risk factor (MRF). Morphological parameters were; plaque composition and echogenecity. Velocity parameters were: peak-systolic velocity (PSV) and end-diastolic velocity (EDV). The following MRF were evaluated: age, gender, hypertension, tobacco smoking, hyperlipidemia (total cholesterol and LDL-cholesterol), obesity, and diabetes mellitus. Examination was performed on CCA/ICA segment. RESULTS: We found significant presence of heterogeneous plaques in TIAs and rIS subgroup, p < 0.014, and borderline significance for the rTIAs and IS subgroups, p < 0.04. We found significant difference in PSV in TIAs and rTIAs subgroups vs. controls (PSV 103 cm/s vs. PSV in controls 87 cm/s, p < 0.01). Decreased EDV, below 20 cm/s, was found in all subgroups, p < 0.01, while EDV, below 16 cm/s, was found in IS and rIS subgroups. MRF score of CVE group was 4.34 vs. 3.65 in controls, p < 0.012, while MRF score in TIAs and rTIAs vs. IS and rIS subgroups was 4.34 vs. 4.51, NS, p = 0.14. We found a significant correlation (95% CI) of tobacco smoking, obesity and arterial hypertension with presence of heterogeneous plaques, p = 0.0069. Interestingly, hyperlipidemia showed no correlation with heterogeneous plaques, p = 0.027. CONCLUSIONS: (i) in CVE group we found significant presence of heterogeneous plaques in TIAs and rIS subgroups, (ii) in the pts with TIAs and rTIAs events we found significant increase in PSV, (iii) EDV below 16 cm/sec was a significant single predictor of IS and rIS events, (iv) MRF score was significantly increase in the pts with CVE compared to controls, but between CVE subgroups there was no significant difference.
