Late presentation of traumatic tricuspid valve chordal rupture and pericardial rupture with cardiac herniation: a case report.

BACKGROUND: Although chest trauma happens very often, accompanying tricuspid valve injuries occur rarely and may be manifested by scarce symptoms and signs. Pericardial rupture with cardiac herniation is even a bigger rarity. Transthoracic echocardiography plays a key role in the diagnosis of valve injuries but is of limited value in cardiac herniation. CASE PRESENTATION: We present the case of 58-year-old man who experienced severe chest trauma in a car accident. Symptoms of right heart failure occurred 10 years after the injury, due to the loss of tricuspid leaflet support caused by the rupture of tendinous chords with significant tricuspid regurgitation. Intraoperatively, old posttraumatic pericardial rupture into left pleura was also found, with partial cardiac herniation and pressure of the edge of pericardium on all left-sided coronary arteries simultaneously. The patient was successfully operated and is free of symptoms 4 years later. CONCLUSIONS: This case emphasizes the importance of timely diagnosis and underlines a mechanism that leads to delayed rupture of the tricuspid valve apparatus. Repeated echocardiography in all patients who experienced chest trauma could be of great importance. Also, given the limited value of echocardiography in posttraumatic pericardial rupture and cardiac herniation, cardiac computed tomography should be performed.

Use of Anticoagulant Therapy in Patients with Acute Myocardial Infarction and Atrial Fibrillation.

The incidence of atrial fibrillation (AF) in acute coronary syndrome (ACS) ranges from 2.3-23%. This difference in the incidence of AF is explained by the different ages of the patients in different studies and the different times of application of both reperfusion and drug therapies in acute myocardial infarction (AMI). About 6-8% of patients who underwent percutaneous intervention within AMI have an indication for oral anticoagulant therapy with vitamin K antagonists or new oral anticoagulants (NOAC).The use of oral anticoagulant therapy should be consistent with individual risk of bleeding as well as ischemic risk. Both HAS-BLED and CHA2DS2VASc scores are most commonly used for risk assessment. Except in patients with mechanical valves and antiphospholipid syndrome, NOACs have an advantage over vitamin K antagonists (VKAs). One of the advantages of NOACs is the use of fixed doses, where there is no need for successive INR controls, which increases the patient's compliance in taking these drugs. The use of triple therapy in ACS is indicated in the case of patients with AF, mechanical valves as well as venous thromboembolism. The results of the studies showed that when choosing a P2Y12 receptor blocker, less potent P2Y12 blockers such as Clopidogrel should be chosen, due to the lower risk of bleeding. It has been proven that the presence of AF within AMI is associated with a higher degree of reinfarction, more frequent stroke, high incidence of heart failure, and there is a correlation with an increased risk of sudden cardiac death. With the appearance of AF in ACS, its rapid conversion into sinus rhythm is necessary, and in the last resort, good control of heart rate in order to avoid the occurrence of adverse clinical events.

Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.

BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

Practical Aspects of Monitoring of Antiplatelet Therapy.

Despite the application of new antiplatelet drugs (prasugrel and ticagrelor), dual antiplatelet therapy with clopidogrel and aspirin remains the standard for patients with acute coronary syndrome undergoing percutaneous coronary intervention, especially in countries of low socioeconomic status. Regardless of the proven benefits, numerous studies have shown that certain groups of patients who receive standard doses of clopidogrel and aspirin do not respond adequately, and many of them also exhibit adverse cardiovascular events. Studies have shown that the risk of stent thrombosis and ischemic complications is higher in patients with: acute coronary syndrome, diabetes mellitus, thrombocytosis, reduced systolic function of the left ventricle with ejection fraction less than 30%, presence of multiple stents, longer and thinner stents, and renal failure. In these patients it is particularly important to assess the response to clopidogrel and selecting adequate antiplatelet therapy; this provides an impetus for platelet function tests. The second especially significant group to target for laboratory evaluation includes patients with increased risk of bleeding, such as elderly patients, patients with low body weight, anemia, thrombocytopenia, renal failure, past or current ventricular or duodenal ulcer, coagulopathy, or liver disease. The third important application of platelet function tests entails the preparation and evaluation of the time for surgical interventions or invasive diagnostic procedures in patients on antiplatelet therapy. These tests can also be helpful for monitoring the effects of therapy of bleeding due to platelet dysfunction. For high-risk patients the careful selection of optimal antiplatelet drug(s) on the basis of estimated individual risk of thrombosis and bleeding, pharmacodynamic characteristics of each drug, and patient̀s comorbidity remains essential.

Significance of Nissen fundoplication after endoscopic radiofrequency ablation of Barrett's esophagus.

OBJECTIVE: HALO radiofrequency ablation (RFA) has been proven as safe and efficient in eradication of both non- and dysplastic Barrett's esophagus (BE). Definitive post-RFA treatment is yet to be determined. METHODS: RFA was performed in 56 patients with BE, 38 with intestinal metaplasia (IM) and 18 with low-grade dysplasia (LGD), and repeated in case of residual BE. Length of the BE was classified according to C&M criteria. Follow-up included regular upper GI endoscopies with biopsies 6 months, 1 and 2 years after the complete resolution of BE. Patients were divided into two groups regarding post-RFA treatment: those maintaining proton pump inhibitors (PPI) daily and those submitted to laparoscopic Nissen fundoplication (LNF) at least 3 months after BE eradication or synchronous with RFA. RESULTS: There were no perforations or strictures related to RFA. Complete endoscopic resolution of BE was observed in 83.92 % patients (86.84 % IM and 77.77 % LGD), in 25 that maintained PPI and 22 in whom LNF was done. In PPI group, 2-year follow-up revealed BE recurrence in biopsy samples in 20 % of patients, while in LNF group 9.1 % of patients had recurrent IM. In overall sample of patients, no difference was noted regarding the influence of post-RFA treatment (p < 0.423). LNF proved superiority over PPI treatment in patients with long-segment BE (cutoff C > 4 cm, p < 0.021). CONCLUSION: HALO RFA is a safe procedure, with high rate of success in complete eradication of BE in symptomatic GERD patients. LNF provides good protection for neosquamous epithelium and in selected group of patients could be offered as a first line of treatment after HALO RFA.

Clinical value of immunoscintigraphy in the rectal carcinomas: immunoscintigraphy of rectal carcinomas.

BACKGROUND/AIM: The aim of this study was to evaluate the clinical reliability of the immunoscintigraphy with radiolabeled monoclonal antibodies for the detection of metastases and recurrences of rectal carcinomas. METHODOLOGY: A total of 65 patients underwent immunoscintigraphy with radiolabeled monoclonal antibodies. Indication for that examination was suspicious rectal cancer or suspicious rectal cancer recurrence and/or metastases. RESULTS: The method proved to have 92.7% sensitivity, specificity 83.3%, positive predictive value 90.5%, negative predictive value 87.0% and accuracy 89.2%. There was a statistically significant relationship between immunoscintigraphy findings and rectoscopy findings (rs=0.415, p=0.013), as well as significant relationship between immunoscintigraphy findings and US findings (rs=0.332, p=0.001). Tumor marker levels were in positive correlation with findings of immunoscintigraphy (rs=0.845, p=0.001), especially raised CEA level (rs=0.816, p=0.004). Patients with higher CA19-9 level had higher Duke's stage (p=0.025). CONCLUSIONS: We can conclude that immunoscintigraphy can be helpful in the detection of metastases and recurrences of colon carcinomas.

Gallbladder motility disorders estimated by non-invasive methods.

BACKGROUND/AIMS: The aim is to compare the radionuclide (DC) and ultrasonographic (US) method in the assessment of gallbladder (GB) motility. METHODOLOGY: The study was performed in 15 controls (C), 10 patients with acute cholecystitis (AC), 20 patients with chronic acalculous cholecystitis (CAC), 26 patients with chronic cholecystitis with calculosis (CCC) as well as in 15 patients with GB dyskinesia (D). GB emptying period (EP), ejection fraction (EF) and ejection rate (ER) were estimated with dynamic cholescintigraphy (DC) and US. RESULTS: The DC and US finding in the patients with AC was typical in all the patients, i.e. GB was not visualized at all on DC, while on US, stone was visible in the cystic duct. There were significant differences (p<0.05) between the EF and ER values obtained between C and the three groups of patients CAC, CCC and D, using both methods. However, there were no significant differences in EF, EP and ER values among CAC, CCC and D (p>0.05). There was also high correlation between the results obtained with both methods in all the groups of patients studied. CONCLUSIONS: The results obtained by both methods are valuable for the assessment of GB motility. Although there are no significant differences and there is a high correlation between the values, radionuclide method is more precise, because it can register motility continuously.

Early and Late Mortality Predictors in Patients with Acute Aortic Dissection Type B.

Background/Aim: Despite technological advances in diagnosis and treatment, in-hospital mortality with acute aortic dissection type B is still about 11%. The purpose of this study was to assess the risk factors for early and long-term adverse outcomes in patients with acute aortic dissection type B treated medically or with conventional open surgery. Methods: The present study included 104 consecutive patients with acute aortic dissection type B treated in our Center from January 1st, 1998 to January 1st, 2007. Patient demographic and clinical characteristics as well as in-hospital complications were reviewed. Univariate and multivariate testing was performed to identify the predictors of in-hospital (30-day) and late (within 9 years) mortality. Results: 92 (88.5%) patients were treated medically, while 12 (11.5%) patients with complicated acute aortic dissection type B were treated by open surgical repair. In-hospital complications occurred in 35.7% patients, the most often being acute renal failure (28%), hypotension/shock (24%), mesenteric ischemia (12%), and limb ischemia (8%). The in-hospital mortality rate was 15.7% and the 9-year mortality rate was 51.9%. Independent predictors of early mortality in patients with acute aortic dissection type B were uncontrolled hypertension (HR-20.69) and a dissecting aorta diameter >4.75 cm (HR-6.30). Independent predictors of late mortality were relapsing pain (HR-7.93), uncontrolled hypertension (HR-7.25), and a pathologic difference in arterial blood pressure (>20 mmHg) (HR-5.33). Conclusion: Knowledge of key risk factors may help with a better choice of treatment and mortality reduction in acute aortic dissection type B patients.

Dilemmas in the Choice of Adequate Therapeutic Treatment in Patients with Acute Pulmonary Embolism-From Modern Recommendations to Clinical Application.

Pulmonary thromboembolism is a very common cardiovascular disease, with a high mortality rate. Despite the clear guidelines, this disease still represents a great challenge both in diagnosis and treatment. The heterogeneous clinical picture, often without pathognomonic signs and symptoms, represents a huge differential diagnostic problem even for experienced doctors. The decisions surrounding this therapeutic regimen also represent a major dilemma in the group of patients who are hemodynamically stable at initial presentation and have signs of right ventricular (RV) dysfunction proven by echocardiography and positive biomarker values (pulmonary embolism of intermediate-high risk). Studies have shown conflicting results about the benefit of using fibrinolytic therapy in this group of patients until hemodynamic decompensation, due to the risk of major bleeding. The latest recommendations give preference to new oral anticoagulants (NOACs) compared to vitamin K antagonists (VKA), except for certain categories of patients (patients with antiphospholipid syndrome, mechanical valves, pregnancy). When using oral anticoagulant therapy, special attention should be paid to drug-drug interactions, which can lead to many complications, even to the death of the patient. Special population groups such as pregnant women, obese patients, patients with antiphospholipid syndrome and the incidence of cancer represent a great therapeutic challenge in the application of anticoagulant therapy. In these patients, not only must the effectiveness of the drugs be taken into account, but great attention must be paid to their safety and possible side effects, which is why a multidisciplinary approach is emphasized in order to provide the best therapeutic option.

Matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) in preoperative serum as independent prognostic markers in patients with colorectal cancer.

Colorectal cancer is one of the leading causes of cancer related death in developed countries. One of the reasons is the absence of tumor specific diagnostic and prognostic markers. The aim of this study was to examine the correlation of matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) expressions in serum and clinicopathological features of the colorectal adenocarcinoma. Another aim was to examine expression of MMP-9 in the tissue of the colorectal carcinoma in MMP-9 serum positive patients. In addition, we tried to establish the correlation between preoperative levels of serum markers (CEA and CA 19-9) and presence of MMP-2 or MMP-9. The study was performed on 32 patients with colorectal adenocarcinoma who underwent surgery and 11 patients in a control group who were operated for benign diseases. The samples were analyzed by SDS-PAGE to determine the molecular mass and SDS-PAGE zymography to determine levels of MMP-2 and MMP-9. Expression of MMP-9 was determined immunohistochemically in the tissue of the colorectal carcinoma of MMP-9 serum positive patients. MMP-2 and MMP-9 levels were increased in the serum of the patients with colorectal cancer compared to the control group. There was significant correlation in MMPs levels among the patients with tumor stage I and II and the patients with tumor stage III and IV. Obtained results did not demonstrate correlation between levels of CEA, CA 19-9 and presence of MMP-2 or MMP-9. MMP-9 expression was positive in 85% of MMP-9 serum positive patients with colorectal carcinoma. The overexpression of MMP-2 and MMP-9 strongly suggests its association with colorectal adenocarcinoma. Detection of MMP-2 and MMP-9 in serum might be useful for identification of patients with higher risk for colorectal cancer recurrence.

Colon interposition for pharyngoesophageal postcorrosive strictures.

BACKGROUND/AIM: Aim of this paper is to report a 40 years experience in performing colon interposition for pharyngoesophageal caustic injury. METHODOLOGY: In the period between 1965 and 2005, 83 colon interpositions were performed due to the pharyngeal and high esopahageal injuries. Patients were classified according to the uppermost level of stricture in 3 groups: supraglotic, hypopharyngeal and esophageal ostium. In most of the patients (89.1%) an extrapleural retrosternal by-pass colon interposition was performed, while in the remaining 10.9% a colon interposition with esophagectomy had to be done. Long-term follow-up results were obtained in the period between one and up to 30 years. RESULTS: Early postoperative complications occurred in 16.8% of patients, among which anastomotic leakage was the most common. Overall intrahospital mortality rate was 6%, while late postoperative complications were present in 14.4% of patients. Long-term follow-up was obtained in 84.2% of patients, with excellent functional results being present in 86.7% of them. CONCLUSION: Colon graft is an excellent esophageal substitute for patients with pharyngoesophageal corrosive strictures, and used by experienced surgical team it provides low postoperative morbidity as well as mortality rate, and a long time good and functional quality of life.

In-hospital and long-term prognosis after myocardial infarction in patients with prior coronary artery bypass surgery; 19-year experience.

To present a 19-year experience of the prognosis of patients with acute myocardial infarction (AMI) and prior coronary artery bypass surgery (CABS), 748 patients with AMI after prior CABS (postbypass group) and a control group of 1080 patients with AMI, but without prior CABS, were analyzed. All indexes of infarct size were lower in the postbypass group. There was more ventricular fibrillation in the postbypass group. In-hospital mortality was similar (p = 0.3675). In the follow-up period, postbypass patients had more heart failure, recurrent CABS, reinfarction, and unstable angina than did control patients. Cumulative survival was better in the control group than in the postbypass group (p = 0.0403). Multiple logistic regression model showed that previous angina (p = 0.0005), diabetes (p = 0.0058), and age (p = 0.0102) were independent predictor factors for survival. Use of digitalis and diuretics, together with previous angina, also influenced survival (p = 0.0092), as well as male gender, older patients, and diabetes together (p = 0.0420). Patients with AMI after prior CABS had smaller infarct, but more reinfarction, reoperation, heart failure, and angina. Previous angina, diabetes, and age, independently, as well as use of digitalis and diuretics together with angina, and male gender, older patients, and diabetes together, influenced a worse survival rate in these patients.

The timing of infarction pain in patients with acute myocardial infarction after previous revascularization.

Circadian variation of onset of acute myocardial infarction (AMI) has been noted in many studies, but there are no data about subgroups of patients with previous coronary artery bypass grafting (CABG). Because of abnormalities in the circadian rhythm of autonomic tone after surgery, it was very interesting to analyze the circadian patterns in the onset of symptoms of AMI in various subgroups of 1784 patients with previous CABG. As in the other studies, a peak occurred in the morning hours with 26.3% of the patients, but there was a second nearly equal, but higher, peak (26.4%) in the evening hours. The subgroups with specific clinical characteristics exhibited different patterns that determined these peaks in all populations. In patients older than 70 years of age, in both sexes, in smokers, diabetics, in patients with hypertension, in those undergoing beta-blocker therapy, and in patients without previous angina, two nearly equal peaks were observed, with higher evening peaks, except in those patients with hypertension and without angina. Only one peak in the evening hours was observed in a subgroup of patients with previous congestive heart failure (CHF) and non-STEMI. The subgroup of patients with previous angina and previous AMI exhibited no discernible peaks. The distribution of time of onset within the four intervals was not uniform, and the difference was statistically significant only for patients undergoing beta-blocker therapy at time of onset (p = 0.0013), nonsmokers (p = 0.0283), and patients with non-STEMI (p = 0.0412). It is well known that patients with AMI have a dominant morning peak of circadian variation of onset. However, analyzing a different subgroup of patients with AMI after previous CABG, it was found that some subgroups had two peaks of onset, but a higher evening peak (patients older than 70 years of age, smokers, diabetics, and a group of patients who were taking beta-blocker therapy). This subgroup of patients, together with the subgroups of patients with a dominant evening peak (patients with CHF and those with non-STEMI) and with patients with no peak (patients with previous angina and previous AMI), probably appear to modify characteristic circadian variation of infarction onset, expressing a higher evening peak, respectively to the previous CABG, with adverse consequences for central nervous system functioning.

Detection of gelatinase B activity in serum of gastric cancer patients.

AIM: To determine the proteolytic activity and expression of gelatinase B in serum of gastric cancer patients and their correlation with the stage of the tumor. METHODS: Sera from 23 patients who underwent surgery for primary gastric cancer as the experimental group and from 11 as the control group were used to determine the proteolytic activity and its inhibition by EDTA and 1,10-phenanthroline. Gelatinase B activity was detected by SDS polyacrylamide gel electrophoresis (SDS-PAGE) and SDS-PAGE zymography. RESULTS: Proteolytic enzyme activity was increased in gastric cancer patients when compared to the control group (P < 0.05). The proteinases were determined to be metalloproteinases upon inhibition test with specific metalloproteinase inhibitors 1,10-phenanthroline (P < 0.05) and EDTA (P < 0.01). SDS-PAGE and SDS-PAGE zymography revealed gelatinase B (proMMP-9) activity and its molecular mass of 92 ku. CONCLUSION: Proteinase activity is overexpressed in serum of gastric cancer patients. Gelatinase B in serum plays an important role in the progression of gastric cancer. ProMMP-9 can be used as a marker for invasiveness of gastric cancer.

Usefulness of NT-proBNP in the Follow-Up of Patients after Myocardial Infarction.

BACKGROUND: Since serial analyses of NT-proBNP in patients with acute coronary syndromes have shown that levels measured during a chronic, later phase are a better predictor of prognosis and indicator of left ventricular function than the levels measured during an acute phase, we sought to assess the association of NT-proBNP, measured 6 months after acute myocardial infarction (AMI), with traditional risk factors, characteristics of in-hospital and early postinfarction course, as well as its prognostic value and optimal cut-points in the ensuing 1-year follow-up. METHODS: Fasting venous blood samples were drawn from 100 ambulatory patients and NT-proBNP concentrations in lithium-heparin plasma were determined using a one-step enzyme immunoassay based on the ¼sandwich« principle on a Dimension RxL clinical chemistry system (DADE Behring-Siemens). Patients were followed-up for the next 1 year, for the occurrence of new cardiac events. RESULTS: Median (IQR) level of NT-proBNP was 521 (335-1095) pg/mL. Highest values were mostly associated with cardiac events during the first 6 months after AMI. Negative association with reperfusion therapy for index infarction confirmed its long-term beneficial effect. In the next one-year follow-up of stable patients, multivariate Cox regression analysis revealed the independent prognostic value of NT-proBNP for new-onset heart failure prediction (p=0.014), as well as for new coronary events prediction (p=0.035). Calculation of the AUCs revealed the optimal NT-proBNP cut-points of 800 pg/mL and 516 pg/mL, respectively. CONCLUSIONS: NT-proBNP values 6 months after AMI are mainly associated with the characteristics of early infarction and postinfarction course and can predict new cardiac events in the next one-year follow-up.

Sex and age differences and outcomes in acute coronary syndromes.

BACKGROUND: There is conflicting information about sex differences in presentation, treatment, and outcome after acute coronary syndromes (ACS) in the era of reperfusion therapy and percutaneous coronary intervention. The aim of this study was to examine presentation, acute therapy, and outcomes of men and women with ACS with special emphasis on their relationship with younger age (≤65years). METHODS: From January 2010 to June 2015, we enrolled 5140 patients from 3 primary PCI capable hospitals. Patients were registered according to the International Survey of Acute Coronary Syndrome in Transitional Countries (ISACS-TC) registry protocol (ClinicalTrials.gov: NCT01218776). The primary outcome was the incidence of in-hospital mortality. RESULTS: The study population was constituted by 2876 patients younger than 65years and 2294 patients older. Women were older than men in both the young (56.2±6.6 vs. 54.1±7.4) and old (74.9±6.4 vs. 73.6±6.0) age groups. There were 3421 (66.2%) patients with ST elevation ACS (STE-ACS) and 1719 (33.8%) patients without ST elevation ACS (NSTE-ACS). In STE-ACS, the percentage of patients who failed to receive reperfusion was higher in women than in men either in the young (21.7% vs. 15.8%) than in the elderly (35.2% vs. 29.6%). There was a significant higher mortality in women in the younger age group (age-adjusted OR 1.52, 95% CI: 1.01-2.29), but there was no sex difference in the older group (age-adjusted OR 1.10, 95% CI: 0.87-1.41). Significantly sex differences in mortality were not seen in NSTE-ACS patients. CONCLUSIONS: In-hospital mortality from ACS is not different between older men and women. A higher short-term mortality can be seen only in women with STEMI and age of 65 or less.

Effects of glucose-insulin-potassium infusion on ST-elevation myocardial infarction in patients treated with thrombolytic therapy.

The role of glucose-insulin-potassium (GIK) infusion in the management of acute myocardial infarction is not well established. This prospective, randomized study comprised 120 patients who had ST-elevation myocardial infarction that was treated within 12 hours from symptom onset with a high dose of GIK (25% glucose, 50 IU of soluble insulin per liter, and 80 mmol of potassium chloride per liter at 1 ml/kg/hour over 24 hours) as adjunct to thrombolytic therapy (1.5 MU of streptokinase/30 to 60 minutes; GIK group) or thrombolytic therapy alone (control group). The primary end point of the study was the rate of major adverse cardiac events (MACEs) at 1 month, defined as a composite of cardiac death, reinfarction, serious arrhythmias (ventricular fibrillation and/or tachycardia), and severe heart failure. The secondary end points were the rate of MACEs at 1 year and improvement in left ventricular systolic function. The incidence of MACEs at 1 month was significantly lower in the GIK group (10% vs 32.5%, relative risk 0.24, 95% confidence interval 0.09 to 0.63, p = 0.0043). Patients in the GIK group had significant decreases in ventricular tachycardia and/or fibrillation (1.3% vs 15.0%, p = 0.003) and severe heart failure (3% vs 12.5%, p = 0.031). The rate of MACEs at 1 year was also significantly lower in the GIK group (13% vs 40.0%, relative risk 0.22, 95% confidence interval 0.09 to 0.55, p = 0.0012). After 1 year, there was a significant improvement in left ventricular ejection fraction in the GIK group (from 48 +/- 8% to 51 +/- 10%, p <0.01), which was not observed in the control group. In conclusion, high-dose GIK, used as an adjunct to thrombolytic therapy, was safe and improved clinical outcome at 1 month. The beneficial effect of GIK infusion was maintained up to 1 year.

Glycogen phosphorylase BB in myocardial infarction.

Early experimental and clinical reports on glycogen phosphorylase BB (GPBB) kinetics following myocardial ischemic injury suggested that it could be a useful diagnostic marker for early detection of acute myocardial infarction (AMI). After more than two decades of investigation, there is now overwhelming body of evidence that do not support the use of GPBB measurement in diagnosis of acute AMI in patients presenting with acute chest pain. Currently, GPBB cannot be recommended as a diagnostic marker of AMI either as a stand-alone test or as an addition to (high-sensitive) troponin testing. It should be noted that these considerations apply to the early diagnosis of AMI, not to the prognostic stratification, which is also suggested but it warrants further investigation. The aim of this review is to summarize available evidence of GPBB measurement in early diagnosis of myocardial infarction.

Surgical treatment of median arcuate ligament syndrome: case report and review of literature.

INTRODUCTION: Median arcuate ligament (MAL) syndrome, also called celiac trunk compression syndrome (CACS) or Dunbar syndrome is a rare disorder caused by compression of the celiac artery by median arcuate ligament of the diaphragm, which leads to mesenteric ischemia and chronic abdominal angina. The typical clinical triad of symptoms includes postprandial epigastric pain, weight loss and vomiting. The gold standard for MAL syndrome diagnosis is selective angiography, while in symptomatic patients with angiographically verified stenosis the optimal therapy is surgical treatment. CASE OUTLINE: A 40-year-old male patient was presented with epigastric pain, followed by dyspepsia and weight loss. The upper endoscopy showed gastric and duodenal distention with prominent folds of gastric mucosa and slow peristalsis. Selective angiography showed stenosis (90%) of initial segment of the celiac trunk. Adhesiolysis with the transection of the median arcuate ligament was performed. Due to repeated symptoms, the patient was reoperated on the 10th postoperative day with performed adhesiolysis and gastrostomy for gastric nutrition. Two months later, the patient was rehospitalized for closure of gastrostomy. At five years follow-up, selective angiography showed no stenosis of the initial segment of the celiac artery. CONCLUSION: Despite the existing controversy concerning pathophysiological mechanism, the clinical presentation and treatment modalities of patients with MAL syndrome, it is evident that careful selection and adequate surgical treatment may significantly reduce symptoms in these patients.

Highly selective vagotomy and gastrojejunostomy in the treatment of peptic ulcer induced gastric outlet obstruction.

BACKGROUND/AIM: The incidence of peptic ulcer-induced gastric outlet obstruction is constantly declining. The aim of this study was to present our results in the treatment of gastric outlet obstruction with highly selective vagotomy and gastrojejunostomy. METHODS: This retrospective clinical study included 13 patients with peptic ulcer-induced gastric outlet obstruction operated with higly selective vagotomy and gastrojejunostomy. A 3-year follow-up was conducted including clinical interview and upper gastrointestinal endoscopy on 1 and 3 years after the surgery. RESULTS: The most common preoperative symptom was vomiting (in 92.3% of patients). The mean preoperative body mass index was 16.3 +/- 3.1 kg/m2, with 9 patients classified preoperatively as underweight. There were no intraoperative complications, nor mortality. At a 3-year follow-up there was no ulcer recurrence. Delayed gastric emptying was present in 1, bile reflux in 2, and erosive gastritis in 1 patient. Two patients suffered from mild "dumping" syndrome. CONCLUSION: Higly selective vagotomy combined with gastrojejunostomy is a safe and easily feasible surgical solution of gastric outlet obstruction induced by peptic ulcer. Good functional results and low rate of complications can be expected at a long-term follow-up.
