Abstract
BACKGROUND The presented study investigates the application of bi-arterial 3D printed models to guide transseptal puncture (TSP) in left atrial appendage closure (LAAC). AIMS The objectives are to (1) test the feasibility of 3D printing (3DP) for TSP guidance, (2) analyse the distribution of the optimal TSP locations, and (3) define a CT-derived 2D parameter suitable for predicting the optimal TSP locations. METHODS Preprocedural planning included multiplanar CT reconstruction, 3D segmentation, and 3DP. TSP was preprocedurally simulated in vitro at six defined sites. Based on the position of the sheath, TSP sites were classified as optimal, suboptimal, or nonoptimal. The aim was to target the TSP in the recommended position during the procedure. Procedure progress was assessed post hoc by the operator. RESULTS Of 68 screened patients, 60 patients in five centers (mean age of 74.68 ± 7.64 years, 71.66% males) were prospectively analyzed (3DP failed in one case, and seven patients did not finally undergo the procedure). In 55 patients (91.66%), TSP was performed in the optimal location as recommended by the 3DP. The optimal locations for TSP were postero-inferior in 45.3%, mid-inferior in 45.3%, and antero-inferior in 37.7%, with a mean number of optimal segments of 1.34 ± 0.51 per patient. When the optimal TSP location was achieved, the procedure was considered difficult in only two (3.6%) patients (but in both due to complicated LAA anatomy). Comparing anterior versus posterior TSP in 2D CCT, two parameters differed significantly: (1) the angle supplementary to the LAA ostium and the interatrial septum angle (160.83° ± 9.42° vs. 146.49° ± 8.67°; p = 0.001), and (2) the angle between the LAA ostium and the mitral annulus (95.02° ± 3.73° vs. 107.38° ± 6.76°; p < 0.001), both in the sagittal plane. CONCLUSIONS In vitro TSP simulation accurately determined the optimal TSP locations for LAAC and facilitated the procedure. More than one-third of the optimal TSP sites were anterior.

Abstract
INTRODUCTION Observational studies have shown low bleeding rates in patients with atrial fibrillation (AF) treated by left atrial appendage closure (LAAC); however, data from randomized studies are lacking. This study compared bleeding events among patients with AF treated by LAAC and nonvitamin K anticoagulants (NOAC). METHODS The Prague-17 trial was a prospective, multicenter, randomized trial that compared LAAC to NOAC in high-risk AF patients. The primary endpoint was a composite of a cardioembolic event, cardiovascular death, and major and clinically relevant nonmajor bleeding (CRNMB) defined according to the International Society on Thrombosis and Hemostasis (ISTH). RESULTS The trial enrolled 402 patients (201 per arm), and the median follow-up was 3.5 (IQR 2.6-4.2) years. Bleeding occurred in 24 patients (29 events) and 32 patients (40 events) in the LAAC and NOAC groups, respectively. Six of the LAAC bleeding events were procedure/device-related. In the primary intention-to-treat analysis, LAAC was associated with similar rates of ISTH major or CRNMB (sHR 0.75, 95% CI 0.44-1.27, p = 0.28), but with a reduction in nonprocedural major or CRNMB (sHR 0.55, 95% CI 0.31-0.97, p = 0.039). This reduction for nonprocedural bleeding with LAAC was mainly driven by a reduced rate of CRNMB (sHR for major bleeding 0.69, 95% CI 0.34-1.39, p = .30; sHR for CRNMB 0.43, 95% CI 0.18-1.03, p = 0.059). History of bleeding was a predictor of bleeding during follow-up. Gastrointestinal bleeding was the most common bleeding site in both groups. CONCLUSION During the 4-year follow-up, LAAC was associated with less nonprocedural bleeding. The reduction is mainly driven by a decrease in CRNMB.

Abstract
AIMS The management of congestion is one of the key treatment targets in heart failure. Assessing congestion is, however, difficult. The purpose of this study was to investigate the safety and dynamic response of a novel, passive, inferior vena cava (IVC) sensor in a chronic ovine model. METHODS AND RESULTS A total of 20 sheep divided into three groups were studied in acute and chronic in vivo settings. Group I and Group II included 14 sheep in total with 12 sheep receiving the sensor and two sheep receiving a control device (IVC filter). Group III included an additional six animals for studying responses to volume challenges via infusion of blood and saline solutions. Deployment was 100% successful with all devices implanted; performing as expected with no device-related complications and signals were received at all observations. At similar volume states no significant differences in IVC area normalized to absolute area range were measured (55 ± 17% on day 0 and 62 ± 12% on day 120, p = 0.51). Chronically, the sensors were completely integrated with a thin, reendothelialized neointima with no loss of sensitivity to infused volume. Normalized IVC area changed significantly from 25 ± 17% to 43 ± 11% (p = 0.007) with 300 ml infused. In contrast, right atrial pressure required 1200 ml of infused volume prior to a statistically significant change from 3.1 ± 2.6 mmHg to 7.5 ± 2.0 mmHg (p = 0.02). CONCLUSION In conclusion, IVC area can be measured remotely in real-time using a safe, accurate, wireless, and chronic implantable sensor promising to detect congestion with higher sensitivity than filling pressures.

Abstract
BACKGROUND The aim of the study was to compare healing (assessed by optical coherence tomography [OCT]) of biolimus A9 (BES) and everolimus drug-eluting stents (EES) at 9-month follow-up in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (pPCI). Nine-month clinical and angiographic data were also compared in both groups as well as clinical data at 5 years of follow-up. METHODS A total of 201 patients with STEMI were enrolled in the study and randomized either to pPCI with BES or EES implantation. All patients were scheduled for 9 months of angiographic and OCT follow-up. RESULTS The rate of major adverse cardiovascular events (MACE) was comparable at 9 months in both groups (5% in BES vs. 6% in the EES group; p = 0.87). Angiographic data were also comparable between both groups. The main finding at 9-month OCT analysis was the greatly reduced extent of mean neointimal area at the cost of a higher proportion of uncovered struts in the BES group (1.3 mm² vs. 0.9 mm²; p = 0.0001 and 15.9% vs. 7.0%; p = 0.0001, respectively). At 5 years of clinical follow-up the rate of MACE was comparable between both groups (16.8% vs. 14.0%, p = 0.74). CONCLUSIONS The study demonstrates a very low rate of MACE and good 9-month stent strut coverage of second-generation BES and EES in patients with STEMI. BES showed greatly reduced extent of mean neointimal hyperplasia area at the cost of a higher proportion of uncovered struts when compared to EES. The rate of MACE was low and comparable in both groups at 5 years.

Abstract
The complexity and application range of interventional and diagnostic procedures using contrast media (CM) have recently increased. This allows more patients to undergo procedures that involve CM administration. However, the intrinsic CM toxicity leads to the risk of contrast-induced acute kidney injury (CI-AKI). At present, effective therapy of CI-AKI is rather limited. Effective prevention of CI-AKI therefore becomes crucially important. This review presents an in-depth discussion of CI-AKI incidence, pathogenesis, risk prediction, current preventive strategies, and novel treatment possibilities. The review also discusses the difference between CI-AKI incidence following intraarterial and intravenous CM administration. Factors contributing to the development of CI-AKI are considered in conjunction with the mechanism of acute kidney damage. The need for ultimate risk estimation and the prediction of CI-AKI is stressed. Possibilities of CI-AKI prevention is evaluated within the spectrum of existing preventive measures aimed at reducing kidney injury. In particular, the review discusses intravenous hydration regimes and pre-treatment with statins and N-acetylcysteine. The review further focuses on emerging alternative imaging technologies, alternative intravascular diagnostic and interventional procedures, and new methods for intravenous hydration guidance; it discusses the applicability of those techniques in complex procedures and their feasibility in current practise. We put emphasis on contemporary interventional cardiology imaging methods, with a brief discussion of CI-AKI in non-vascular and non-cardiologic imaging and interventional studies.

Abstract
BACKGROUND The PRAGUE-17 trial demonstrated that left atrial appendage closure (LAAC) was non-inferior to non-warfarin oral anticoagulants (NOAC) for preventing major neurological, cardiovascular or bleeding events in high-risk patients with atrial fibrillation (AF). OBJECTIVE To assess the pre-specified long-term (4-year) outcomes in PRAGUE-17. METHODS PRAGUE-17 was a randomized non-inferiority trial comparing percutaneous LAAC (Watchman or Amulet) with NOACs (95% apixaban) in non-valvular AF patients with a history of cardioembolism, clinically-relevant bleeding, or both CHA2DS2-VASc > 3 and HASBLED > 2. The primary endpoint was a composite of cardioembolic events (stroke, transient ischemic attack, or systemic embolism), cardiovascular death, clinically-relevant bleeding, or procedure/device-related complications (LAAC group only). The primary analysis was modified intention-to-treat (mITT). RESULTS We randomized 402 AF patients (201 per group, age 73.3±7.0 years, 65.7% male, CHA2DS2-VASc 4.7+1.5, HASBLED 3.1+0.9). After 3.5 years median follow-up (1,354 patients-years), LAAC was non-inferior to NOAC for the primary endpoint by mITT (subdistribution hazard ratio[sHR] 0.81, 95% CI 0.56-1.18; p=0.27; p for non-inferiority=0.006). For the components of the composite endpoint, the corresponding sHRs (and 95% CIs) were 0.68 (0.39-1.20; p=0.19) for cardiovascular death, 1.14 (0.56-2.30; p=0.72) for all-stroke/TIA, 0.75 (0.44-1.27; p=0.28) for clinically-relevant bleeding, and 0.55 (0.31-0.97; p=0.039) for non-procedural clinically-relevant bleeding. The primary endpoint outcomes were similar in the per-protocol [sHR 0.80 (95% CI 0.54-1.18), p=0.25] and on-treatment [sHR 0.82 (95% CI 0.56-1.20), p=0.30] analyses. CONCLUSION In long-term follow-up of PRAGUE-17, LAAC remains non-inferior to NOACs for preventing major cardiovascular, neurological or bleeding events. Furthermore, non-procedural bleeding was significantly reduced with LAAC.

Abstract
INTRODUCTION Reperfusion therapy by primary percutaneous coronary intervention (PPCI) is generally indicated in patients suffering from acute myocardial infarction (MI) with ST-segment elevation (STEMI). Prior to hospital admission, full ST-segment resolution (fSTR) may occur. Optimal management of such patients with transient STEMI (TSTEMI) is potentially challenging. Our aim was to evaluate the hypothesis that in TSTEMI patients, patency of infarct related artery (IRA) is achieved before PPCI, and to compare the outcome of TSTEMI and STEMI patients during a prolonged follow-up. MATERIAL AND METHODS Three hundred consecutive adult STEMI patients were referred to catheterization laboratory. In all patients, standard 12 lead ECGs were obtained both at the time of the first medical contact, and on catheterization laboratory admission. RESULTS TSTEMI occurred in 20 patients (6.7%). Despite fSTR (isoelectric ST segment), occluded IRA was found in 5 of these patients (25%). Pre-PPCI TIMI flow grade 2 was found in 6 TSTEMI patients (30%). Troponin T value at 24 h after symptom onset was lower in the TSTEMI group (1.8±2.5 mg/L vs. 3.6±3.5 mg/L, P=0.008). These patients also had a lower value of brain natriuretic peptide (156.3±119.5 ng/L vs. 438.5±429.0 ng/L, P<0.001) and higher left ventricular ejection fraction (59.9±6.3% vs. 51.6±10.2%, P<0.001). All patients were followed for a median of 5.6 years during which the overall survival did not differ between the TSTEMI and STEMI groups. CONCLUSION Primary PCI is strongly recommended in TSTEMI patients because of a relatively high incidence of occluded infarct related arteries. The rate of patients with TSTEMI is relatively low.

Abstract
The link between patent foramen ovale (PFO) and paradoxical embolization, which may be cause of so-called “cryptogenic” ischemic stroke, has been known for more than 100 years. The catheteriziation closure of PFO as a secondary preventive treatment is performed in a greater extent since the end of the last century. The results of the first epidemiological and randomised clinical trials comparing antiagregation or anticoagulant therapy with the PFO closure did not show a clear benefit of any of these approaches. In 2017, major randomized clinical trials were published that demonstrated the benefit of PFO catheter closure compared to drug therapy alone. In this summary article we describe the diagnostic procedure of patients with PFO undergoing paradoxical embolization, indications and selections of a suitable patient for catheter closure of PFO, the procedure itself and subsequent clinical follow-up of these patients.

Abstract
Amiodarone is one of the more frequently used drugs in the treatment of supraventricular and ventricular arrhythmias. Many adverse effects, more or less serious, are associated with its administration. Amiodaron-induced pulmonary toxicity (AIPT) is quite rare but represents one of the most severe adverse effects with high mortality. We present an 80 years old patient, who used amidorane due to paroxysmal atrial fibrillation for several years. Within 3 months, he was repeatedly hospitalized for a bilateral pneumonia. Eventually, AIPT was diagnosed. Early diagnosis, proper therapy of AIPT and changed antiarrhythmic therapy has significantly improved the clinical status of our patient. In this case we demonstrate typical clinical presentations of AIPT as well as the most common diagnostic procedures and recommended treatment methods. Finally, some other commonly used therapeutical options for supraventricular arrhythmias are mentioned. Future options are outlined.

Abstract
Chronic total occlusion is characterised by total discontinuation of a blood flow in coronary vessel present for at least three months. Typical finding involves filling of the distal arterial segments by collateral flow. Well developed collaterals usually provide sufficient supply to preserve myocardial viability, but frequently are not capable of preventing excercise ischemia in the occluded territory. Percutaneous intervention of a CTO is focused on ischemia reduction, improvement of excercise capacity and quality of life. A succesful recanalization of a CTO leads to an improvement of left ventricular systolic function. Patients presenting with acute coronary syndromes and a coincident CTO in non-infarct related artery show worse short and long-term outcomes as compared to patients without a CTO. Technolocigal and procedural evolvement over past decades with implementation of novel techniques used by experienced operators lead to a substantial succes rate imprevement with acceptable complications rate in contemporary CTO interventions.

Abstract
Contrast induced nephropathy is associated with worse clinical outcome in patients undergoing coronary intervention. The most profound risk factor is advanced chronic renal insufficiency. Due to the increasing number of coronary interventions on severally ill patients, there is a need of modern therapeutic approach that could reduce the volume of contrast media to minimum or even zero. Herein, the authors present a case report of a 68-year-old patient with chronic kidney disease, who required elective coronary intervention (PCI) due to a significant lesion of the left anterior descending coronary artery. During this intervention, maximum emphasis was given on reduction of contrast media. To the best of our knowledge, this was the first similar intervention performed in the Czech Republic. Minimum contrast PCI guided by the intracoronary ultrasound, i.e. the IVUS-guided zero-contrast PCI may serve as a potential alternative to standard, angiography-guided PCI.

Abstract
Takotsubo or broken heart syndrome represents a rare type of cardiomyopathy, often imitating acute myocardial infarction. It is a sudden transient cardiac syndrome that typically involves left ventricular apical akinesis with preserved motility of basal heart segments. In contrast to acute myocardial infarction, the pathology is fully reversible in the majority of patients. In the present casereport, we discuss 78yearsold female referred to our department for typical symptomatology of acute myocardial infarction. Coronary angiography revealed significant stenosis on the left anterior descending coronary artery, but ventriculography disclosed apical dysfunction and clinical course of the disease result in the diagnosis of Takotsubo cardiomyopathy. Until recently, normal or nonobstructive coronary angiography represented one of the mean diagnostic features of Takotsubo cardiomyopathy. In 2018, new diagnostic criteria were introduced, importantly modifying our approach to the Takotsubo diagnostics with omitting a coronary lesion as an exclusion criterium of the Takotsubo cardiomyopathy.

Abstract
Background
Takotsubo cardiomyopathy (TTC) is a severe cardiologic disorder with an increasing incidence that often mimics acute coronary syndrome. Both of the entities are characterized by systolic dysfunction of the left ventricle myocardium. However, this dysfunction is reversible in most cases of TTC. Takotsubo syndrome affects predominantly postmenopausal females, typically with a direct link to emotional or physical stress factors. The pathophysiology of TTC remains unclear. In this study, we aimed to assess the pathophysiology of TTC using the invasive functional testing of coronary microcirculation.
Methods
Ten female patients diagnosed with TTC in line with interTAK Diagnostic Criteria were included in this pilot study. In all subjects we measured fractional and coronary flow reserve in the left anterior descending and left circumflex coronary arteries (FFR LAD, FFR LCx, CFR LAD, CFR LCx), and the index of microcirculatory resistance in the same arteries (iMR LAD, iMR LCx) in addition to acute and late (after 12 weeks) transthoracic echocardiography (TTE) and acute cardiac biomarkers (troponin and NT-proBNP). The results of the microcirculatory assessment were statistically compared with normal population values.
Results
In all subjects, the troponin level was elevated in the acute phase and repeated TTE revealed transient dysfunction of the left myocardial ventricle. Whilst fractional flow reserve was normal in both assessed epicardial artery territories for all patients (mean FFR LAD: 0.92±0.04; mean FFR LCx: 0.98±0.046), both mean values of coronary flow reserve disclosed pathological microcirculatory findings (CFR LAD: 1.9±1.197; CFR LCx: 1.75±0.742) and were pathological in nine out of ten subjects. Index of microcirculatory resistance revealed abnormal values in five out of ten patients for LAD (31.03±18.515) and three out of ten for LCx (23.8±17.86).
Conclusions
Our pilot study confirmed non-obstructive findings in the epicardial coronary arteries assessed by FFR. On the other hand, the investigation of both CFR and iMR, microcirculatory functional testing, revealed pathological findings in a significant number of evaluated subjects. From this aspect, our study validates further research in the field of microcirculatory functions as a possible mechanism in the origin of TTS.

Abstract
AIMS To assess the possible merits of optical coherence tomography (OCT) guidance in primary percutaneous coronary intervention (pPCI). METHODS AND RESULTS 201 patients with ST-elevation myocardial infarction (STEMI) were enrolled in this study. Patients were randomized either to pPCI alone (angio-guided group, n=96) or to pPCI with OCT guidance (OCT-guided group, n=105) and also either to biolimus A9 or to everolimus-eluting stent implantation. All patients were scheduled for nine months of follow-up angiography and OCT study. OCT guidance led to post-pPCI optimization in 29% of cases (59% malapposition and 41% dissections). No complications were found related to the OCT study. OCT analysis at nine months showed significantly less in-segment area of stenosis (6% [-11, 19] versus 18% [3, 33]; p=0.0002) in favor of the OCT-guided group. The rate major adverse cardiovascular events were comparable at nine months in both groups (3% in the OCT group versus 2% in the angio-guided group; p=0.87). CONCLUSIONS This study demonstrates the safety of OCT guidance during pPCI. The use of OCT optimized stent deployment in 1/3 of patients in this clinical scenario and significantly reduced in-segment area of stenosis at nine months of follow-up. Whether such improvements in OCT endpoints will have a positive impact on late clinical outcomes, they demand both a larger and longer-term follow-up study.

Abstract
Aims Transradial catheterization (TRC) is a dominant access site for coronary catheterization and percutaneous coronary interventions (PCI) in many centers. Previous studies reported higher intimal thickness of the radial artery (RA) wall in patients with a previous history of TRC. In this investigation the aim was to assess the intimal changes of RA using the optical coherence tomography (OCT) intravascular imaging in a serial manner. Methods and results 100 patients with the diagnosis of non-ST-elevation myocardial infarction (nSTEMI) treated by PCI were enrolled (6 patients were excluded from this analysis because of occluded RA at follow-up [2 patients] and insufficient quality of OCT images [4 patients]). An 54mm long OCT run of the RA was performed immediately after the index PCI and repeated 9 months later. Volumetric analyses of the intimal layer and lumen changes were conducted. Median intimal volume at baseline versus 9 months was 33.9mm3 (19.0; 69.4) versus 39.0mm3 (21.7; 72.6) (p<0.001); and median arterial lumen volume was 356.3mm3 (227.8; 645.3) versus 304.7mm3 (186.1; 582.7) (p<0.001). There was no significant difference in the effect of any clinical factor on the RA volume changes. Conclusions OCT volumetric analyses at baseline and 9 months showed a significant increase in the radial artery intimal layer volume and a decrease in lumen volume after transradial PCI. No significant factors affecting this process were identified.

Abstract
Atrial fibrillation (AF), with a prevalence of 1% to 2%, is the most common cardiac arrhythmia. Without antithrombotic treatment, the annual risk of a cardioembolic event is 5% to 6%. The source of a cardioembolic event is a thrombus, which is usually formed in the left atrial appendage (LAA). Prevention of cardioembolic events involves treatment with anticoagulant drugs: either vitamin K antagonists or, recently, novel oral anticoagulants (NOAC). The other (nonpharmacologic) option for the prevention of a cardioembolic event involves interventional occlusion of the LAA. OBJECTIVE To determine whether percutaneous LAA occlusion is noninferior to treatment with NOAC in AF patients indicated for long-term systemic anticoagulation. STUDY DESIGN The trial will be a prospective, multicenter, randomized noninferiority trial comparing 2 treatment strategies in moderate to high-risk AF patients (ie, patients with history of significant bleeding, or history of cardiovascular event(s), or a with CHA2DS2VASc ≥3 and HAS-BLED score ≥2). Patients will be randomized into a percutaneous LAA occlusion (group A) or a NOAC treatment (group B) in a 1:1 ratio; the randomization was done using Web-based randomization software. A total of 396 study participants (198 patients in each group) will be enrolled in the study. The primary end point will be the occurrence of any of the following events within 24months after randomization: stroke or transient ischemic attack (any type), systemic cardioembolic event, clinically significant bleeding, cardiovascular death, or a significant periprocedural or device-related complications. CONCLUSION The PRAGUE-17 trial will determine if LAA occlusion is noninferior to treatment with NOAC in moderate- to high-risk AF patients.

Abstract
BACKGROUND AND AIMS Transradial catheterization is the predominant access site for coronary catheterization and percutaneous coronary interventions (PCI). Previous studies have reported a high incidence of radial artery (RA) injury. The aim of this investigation was to evaluate the incidence of RA injury using last generation optical coherence tomography (OCT) intravascular imaging in a serial manner. METHODS 100 patients with a diagnosis of non-ST-elevation myocardial infarction (nSTEMI) treated by PCI were enrolled. OCT of RA was performed immediately after the index PCI. OCT was repeated 9 months later. RESULTS There were 11 patients with RA injuries (11.0%) at baseline, including 3 patients with RA medial dissection and 8 patients with intimal tears. In the follow-up OCT data, the number of RA injuries was 10 (10.0%), including 7 patients with RA medial dissection and 3 patients with intimal tear. All injuries were clinically asymptomatic and there was no finding of vessel perforation. There was no significant difference between the baseline and follow-up procedure in terms of number of injuries. CONCLUSION The study showed no significant difference between baseline and follow-up RA injury incidence. There was a higher risk of radial injury for repeated catheterization in women. The conclusion is that radial catheterization is a very safe procedure in terms of radial artery damage. This is evidenced by considerably fewer injuries compared to published studies. The use of the short radial sheath (7 cm in this study) is protective and reduces the incidence of radial injury.

Abstract
BACKGROUND We compared the prognostic capacity of conventional and novel invasive parameters derived from the slope of the preload recruitable stroke work relationship (PRSW) in STEMI patients and assessed their contribution to the TIMI risk score. METHODS Left ventricular end-diastolic pressure (EDP), ejection fraction (EF), pressure adjusted maximum rate of pressure change in the left ventricle (dP/dt/P), aortic systolic pressure to EDP ratio (SBP/EDP) and end-diastolic volume adjusted stroke work (EW), derived from the slope of the PRSW relationship, were obtained during the emergency cardiac catheterization in 523 STEMI patients. The predictive power of the analyzed parameters for 30-day and 1-year mortality was evaluated using C-statistics and reclassification analysis was adopted to assess the improvement in TIMI score. RESULTS The highest area under the curve (AUC) values for 30-day mortality were observed for EW (0.872(95% confidence interval 0.801-0.943)), SBP/EDP (0.843(0.758-0.928)) and EF (0.833(0.735-0.931)); p<0.001 for all values. For 1-year mortality the best predictive value was found for EW (0.806(0.724-0.887) and EF (0.793(0.703-0.883)); p<0.001 for both. The addition of EDP, SBP/EDP ratio and EW to TIMI score significantly increased the AUC according to De Long's test. For 30-day mortality, increased discriminative power following addition to the TIMI score was observed for EW and SBP/EDP (Integrated Discrimination Improvement was 0.086(0.033-0.140), p=0.002 and 0.078(0.028-0.128), p=0.002, respectively). CONCLUSIONS EW and SBP/EDP are prognostic markers with high predictive value for 30-day and 1-year mortality. Both parameters, easily obtained during emergency catheterization, improve the discriminatory capacity of the TIMI score for 30-day mortality.

Abstract
AIM To compare the prognostic accuracy of six scoring models for up to three-year mortality and rates of hospitalisation due to acute decompensated heart failure (ADHF) in STEMI patients. METHODS AND RESULTS A total of 593 patients treated with primary PCI were evaluated. Prospective follow-up of patients was ≥3 years. Thirty-day, one-year, two-year, and three-year mortality rates were 4.0%, 7.3%, 8.9%, and 10.6%, respectively. Six risk scores--the TIMI score and derived dynamic TIMI, CADILLAC, PAMI, Zwolle, and GRACE--showed a high predictive accuracy for six- and 12-month mortality with area under the receiver operating characteristic curve (AUC) values of 0.73-0.85. The best predictive values for long-term mortality were obtained by GRACE. The next best-performing scores were CADILLAC, Zwolle, and Dynamic TIMI. All risk scores had a lower prediction accuracy for repeat hospitalisation due to ADHF, except Zwolle with the discriminatory capacity for hospitalisation up to two years (AUC, 0.80-0.83). CONCLUSIONS All tested models showed a high predictive value for the estimation of one-year mortality, but GRACE appears to be the most suitable for the prediction for a longer follow-up period. The tested models exhibited an ability to predict the risk of ADHF, especially the Zwolle model.

Abstract
Acute coronary syndrome may develop in the background of hemodynamically non-significant coronary artery disease. It may be caused by the presence of "vulnerable plaque", which is characterized by the lipid rich core and thin fibrous cap content. NIRS - near infrared spectroscopy - is a morphological imaging method allowing determining atherosclerotic plaque cholesterol burden. Information about the chemical composition may contribute to "high risk" plaque early identification and subsequent optimal interventional strategy. The first experience with the clinical implementation of this novel method is demonstrated in a case report. Key words: acute coronary syndrome - chemogram - intravascular imaging - NIRS - vulnerable plaque.

Abstract
Objectives The aim of the work was to find biomarkers identifying patients at high risk of adverse clinical outcomes after TAVI and SAVR in addition to currently used predictive model (EuroSCORE). Background There is limited data about the role of biomarkers in predicting prognosis, especially when TAVI is available. Methods The multi-biomarker sub-study included 42 consecutive high-risk patients (average age 82.0 years; logistic EuroSCORE 21.0%) allocated to TAVI transfemoral and transapical using the Edwards-Sapien valve (n = 29), or SAVR with the Edwards Perimount bioprosthesis (n = 13). Standardized endpoints were prospectively followed during the 12-month follow-up. Results The clinical outcomes after both TAVI and SAVR were comparable. Malondialdehyde served as the best predictor of a combined endpoint at 1 year with AUC (ROC analysis) = 0.872 for TAVI group, resp. 0.765 (p<0.05) for both TAVI and SAVR groups. Increased levels of MDA, matrix metalloproteinase 2, tissue inhibitor of metalloproteinase (TIMP1), ferritin-reducing ability of plasma, homocysteine, cysteine and 8-hydroxy-2-deoxyguanosine were all predictors of the occurrence of combined safety endpoints at 30 days (AUC 0.750–0.948; p<0.05 for all). The addition of MDA to a currently used clinical model (EuroSCORE) significantly improved prediction of a combined safety endpoint at 30 days and a combined endpoint (0–365 days) by the net reclassification improvement (NRI) and the integrated discrimination improvement (IDI) (p<0.05). Cystatin C, glutathione, cysteinylglycine, asymmetric dimethylarginine, nitrite/nitrate and MMP9 did not prove to be significant. Total of 14.3% died during 1-year follow-up. Conclusion We identified malondialdehyde, a marker of oxidative stress, as the most promising predictor of adverse outcomes during the 30-day and 1-year follow-up in high-risk patients with symptomatic, severe aortic stenosis treated with TAVI. The development of a clinical “TAVIscore” would be highly appreciated. Such dedicated scoring system would enable further testing of adjunctive value of various biomarkers.

Abstract
AIMS Tissue inhibitors of metalloproteinase (TIMPs) bind to active matrix metalloproteinase (MMPs), and thereby inhibit their proteolytic activity. We investigated the role of polymorphisms in the gene for TIMP-1 and serum levels of TIMP-1 in association with postmyocardial infarction (MI), left ventricular (LV) dysfunction, and symptoms of acute heart failure (AHF) in patients treated with primary percutaneous coronary intervention. METHODS In total, 556 patients with STEMI were evaluated. Levels of TIMP-1 were measured at admission and 24 h after MI onset. The TIMP-1 exon 5 SNP rs4898 (F124F with T>C) located at X chromosome was assayed. RESULTS TIMP-1 levels were higher for men with AHF as well as for men with LV dysfunction (ejection fraction [EF]<40%). According to multivariate analysis, the TIMP-1 level was a factor with an independent negative relationship to EF and AHF in men. An independent relationship between exon 5 TIMP-1 gene polymorphism and EF, AHF or TIMP-1 level was not documented. CONCLUSION These results provide evidence that a higher level of circulating TIMP-1 is independently associated with worse EF and AHF.

Abstract
AIM The aim of this study was to compare the quality of life after transcatheter aortic valve implantation (TAVI) and surgical replacement (SAVR) at one year. METHODS The study included 45 consecutive high-risk patients (average age 82.0 years; logistic Euroscore 22.3%) with symptomatic severe aortic stenosis allocated to TAVI transfemoral, TAVI transapical using the Edwards-Sapien valve or SAVR with the Edwards Perimount bioprosthesis (n=15 in each). The pre-operative characteristics were similar except for more myocardial infarctions in TAVI. The quality of life was assessed using the standardized EQ-5D questionnaire at baseline and on days 30, 90 and 360. The protocol was approved by the local ethics committee and an informed consent was signed. A total of 7 patients (15.5%) died during follow-up. RESULTS At baseline no significant differences in any of the quality-of-life parameters were found except for usual activities described as "best" (46.7% in SAVR vs. 10.0% in TAVI; P=0.002). At 30 and 90 days surviving patients were similar and at 360 days only the anxiety/depression score was "best" in 83.3% SAVR vs. 59.1% (P=0.046). Functional status improved in all patients (NYHA class I-II in 13.3% at baseline vs. 78.9% at 360-days) and the general health median significantly improved in TAVI patients (from 50 to 67; P=0.001) with a positive trend in SAVR patients (P=0.060). CONCLUSIONS At one year, the general quality of life of high-risk patients had significantly improved after transcatheter aortic valve implantation with a positive trend in surgically treated patients.

Abstract
BACKGROUND Antiarrhythmic properties of statins were suggested as a part of their pleiotropic effects. The aim of the present study was to evaluate the effects of atorvastatin on myocardial repolarization as manifested on surface electrocardiograms (ECGs) in healthy subjects. METHODS AND RESULTS Forty young healthy volunteers (20 men, 20 women) underwent a single-dose double-blind 3-way crossover study of 20 and 80 mg of atorvastatin and placebo. Long-term 13-hour 12-lead ECGs were obtained in each subject and each study period starting 15 minutes before drug administration. Each study period contained 18 time-points of 5-minute durations when the subjects were in resting supine positions. Digital ECG recordings were analyzed automatically, and the results were completed blindly before statistical analyses. Dynamic parameters of myocardial repolarization and T-wave morphology descriptors were evaluated. Although some trends were observed, no significant drug-related changes in any of investigated ECG repolarization descriptors were found. CONCLUSION In comparison with placebo, single doses of atorvastatin had no effect on repolarization heterogeneity in healthy subjects. The observation confirms safe profile of the drug with limited proarrhythmic potential.

Abstract
INTRODUCTION The annual incidence of out-of-hospital cardiac arrest is around 90-190 cases per 100 000 inhabitants. The limiting factor for further prognosis of patients after out-of-hospital arrest is their neurological status. The S100B protein is mainly the nervous system cells product, its glial-specific and mostly expressed by astrocytes. It has been shown that after circulatory arrest its increased level correlates with the prognosis of patients. Work aims to determine the level of protein S100B in the group of patients with acute myocardial infarction without circulatory arrest, and compare it to the value in patients with acute myocardial infarction after out-of-hospital resuscitation. METHODS 24 patients were evaluated after out-of-hospital resuscitation for the malignant arrhythmias during acute coronary syndrome (ACS). All patients were treated with mild therapeutic hypothermia. The control group consisted of 19 patients with ACS. The sample for the determination of S-100B was taken immediately on admission. Neurological status was evaluated according to the CPC scores (Cerebral Performance Categories) at discharge, patients were divided into 3 groups: CPC1 - good condition, CPC2 - moderate neurological disability, CPC3-5 - serious neurological impairment, coma or death. RESULTS The values of protein S-100B fluctuated, in patients with no resuscitation, in range between 0.038 to 0.204 pg/ml. In patients after resuscitation without subsequent neurological disability (CPC 1) was range 0.077 to 0.817 pg/ml, in patients with moderate to severe neurological disability (CPC 2) was range 0.132-2.59 pg/ml, patients with severe neurological disabilities or deaths had S-100B levels from 0.70 to 8.53 pg/ml. According to ROC analysis we found the cut-off value for the S-100B. Cut-off value for probably a good neurological condition is < 0.23 pg/ml (specificity 93%, sensitivity 70%), and value testify for supposed severe neurological disability or death is > 1.64 pg/ml (specificity 95%, sensitivity 83%). CONCLUSION Protein S-100B is one of the early and sensitive markers of severe brain damage in patients after cardiac arrest. Its early determination can help in prediction of patient neurological condition and help doctors to decide further action.

Abstract
AIMS The current guidelines recommend reperfusion therapy in acute myocardial infarction (AMI) with ST-segment elevation or left bundle branch block (LBBB). Surprisingly, the right bundle branch block (RBBB) is not listed as an indication for reperfusion therapy. This study analysed patients with AMI presenting with RBBB [with or without left anterior hemiblock (LAH) or left posterior hemiblock (LPH)] and compared them with those presenting with LBBB or with other electrocardiographic (ECG) patterns. The aim was to describe angiographic patterns and primary angioplasty use in AMI patients with RBBB. METHODS AND RESULTS A cohort of 6742 patients with AMI admitted to eight participating hospitals was analysed. Baseline clinical characteristics, ECG patterns, coronary angiographic, and echocardiographic data were correlated with the reperfusion therapies used and with in-hospital outcomes. Right bundle branch block was present in 6.3% of AMI patients: 2.8% had RBBB alone, 3.2% had RBBB + LAH, and 0.3% had RBBB + LPH. TIMI flow 0 in the infarct-related artery was present in 51.7% of RBBB patients vs. 39.4% of LBBB patients (P = 0.023). Primary percutaneous coronary intervention (PCI) was performed in 80.1% of RBBB patients vs. 68.3% of LBBB patients (P< 0.001). In-hospital mortality of RBBB patients was similar to LBBB (14.3 vs. 13.1%, P = 0.661). Patients with new or presumably new blocks had the highest (LBBB 15.8% and RBBB 15.4%) incidence of cardiogenic shock from all ECG subgroups. Percutaneous coronary intervention was done more frequently (84.8%) in patients with new or presumably new RBBB when compared with other patients with blocks (old RBBB 66.0%, old LBBB 62.3%, new or presumably new LBBB 73.0%). In-hospital mortality was highest (18.8%) among patients presenting with new or presumably new RBBB, followed by new or presumably new LBBB (13.2%), old LBBB (10.1%), and old RBBB (6.4%). Among 35 patients with acute left main coronary artery occlusion, 26% presented with RBBB (mostly with LAH) on the admission ECG. CONCLUSION Acute myocardial infarction with RBBB is frequently caused by the complete occlusion of the infarct-related artery and is more frequently treated with primary PCI when compared with AMI + LBBB. In-hospital mortality of patients with AMI and RBBB is highest from all ECG presentations of AMI. Restoration of coronary flow by primary PCI may lead to resolution of the conduction delay on the discharge ECG. Right bundle branch block should strongly be considered for listing in future guidelines as a standard indication for reperfusion therapy, in the same way as LBBB.

Abstract
BACKGROUND Acute heart failure during ST elevation myocardial infarction (STEMI) makes worse prognosis. The aim of the work was to find independent factors with relationship to acute heart failure (AHF) and the early development of left ventricular dysfunction within the prospective followed patients with STEMI. METHODS A total of 593 patients with STEMI treated by primary PCI (164 patients with AHF) were the study population. The activity of BNP and NT-ProBNP were measured at hospital admission and 24 h after MI onset. Left ventricular angiography was done before PCI; echocardiography was undertaken between the third and fifth day after MI. RESULTS The patients with AHF had higher level of glycaemia, creatinine, uric acid, HDL-cholesterol, leukocytosis and natriuretic peptid. The total hospital mortality was 3.7%. 0.2% within the patients without AHF, 3.2%, 14.3%, resp. 63.6% within the patients with mild AHF, with pulmonary oedema, resp. with cardiogenic shock. The patients with AHF had lower ejection fraction (45.4 +/- 11.9% vs 53.0 +/- 10.3%). According to the multiple logistic regression we found higher glycaemia, age, heart rate, anterior wall MI, lower aortic pulse pressure and collaterals of infarct related artery as factors with independent relationship to AHF. Higher glycaemia, age, heart rate, anterior wall MI and lower aortic pulse pressure were found as independent factors with relationship to left ventricular dysfunction. According to ROC analysis possible cut off corresponding with AHF we suggested 29.5 mm Hg for LVEDP, 28.5 for dP/dt/P, 9.5 mmol/l for glycaemia, 50 mm Hg for aortic pulse pressure. CONCLUSIONS Our results found the development of AHF in one third of patients with STEMI. AHF increases the risk of in-hospital mortality and the risk depends upon severity of failure. As the independent factors with relationship to development of AHF or left ventricular dysfunction we detected higher glycaemia, heart rate, anterior wall MI, age. Lower risk had patients with higher aortic pulse pressure.

Abstract
Background We evaluated the associations among angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism, ACE activity and post-myocardial infarction (MI) left ventricular dysfunction and acute heart failure (AHF) early after presentation with MI with ST-segment elevation (STEMI). Methods A total of 556 patients with STEMI treated by primary PCI (421 patients without AHF and 135 patients with AHF) were the study population. The activity of BNP, NT-ProBNP and ACE were measured at hospital admission and 24 h after MI onset. Left ventricular angiography was done before PCI; echocardiography was undertaken between the third and fifth day after MI. Results In comparison with the II genotypes group, the DD/ID group had a higher level of ACE activity upon hospital admission (p < 0.001). We found a significantly higher level of ACE activity in patients with moderate LV dysfunction (EF 40-54%) in comparison both with patients with preserved LV function (EF ≥55%) and with patients with severe LV dysfunction (p = 0.028). A non-significant trend towards a higher incidence of mild AHF (22.1% vs. 16.02%, p = 0,093), a significantly higher value of end-systolic volume (ESV/BSA) (30.0 ± 12.3 vs. 28.5 ± 13.0; p < 0.05) and lower EF (50.2 ± 11.1 vs. 52.7 ± 11.7; p < 0.05) in the DD/ID genotypes group was noted. Even after multiple adjustments according to multivariate models, the EF for the DD/ID group remained significantly lower (p = 0,033). The DD/ID genotypes were associated with a significantly higher risk of EF <45% (OR 2.04 [95% CI 1.28; 3.25]). Conclusions These results suggest that the I/D polymorphism of ACE is associated with the development of LV dysfunction in the acute phase after STEMI. We demonstrated for the first time an association of the low ACE activity with the severe LV dysfunction, although patients with moderate LV dysfunction had higher level ACE activity than patients with preserved LV function.

Abstract
AIM Utilization of cardiac catheterization has increased dramatically over time. Bleeding is a major prognostic predictor after percutaneous coronary catheterization procedures. This study aimed to assess the impact of eight polymorphisms of genes encoding platelet receptors and enzymes on the risk of bleeding in patients undergoing elective coronary angiography (CAG). METHODS Polymorphisms of platelet receptors, GP Ia (807C>T, rs1126643), GP VI (13254T>C, rs1613662), GP IIIa (HPA-1, rs5918), PAR-1 (IVS-14A>T, rs168753), P2Y(12) (34C>T, rs6785930 and H1/H2 haplotype, rs2046934), and genetic variations of the gene coding for cyclooxygenase-1 (COX-1) (-842A>G, rs10306114 and 50C>T, rs3842787) were studied. The frequencies of gene polymorphisms carriers were investigated in 696 patients undergoing elective CAG because of suspected or proven stable coronary artery disease. Genotyping was done using PCR, followed by melting curve analysis with specific fluorescent hybridization probes. RESULTS In patients undergoing elective CAG (without ad hoc percutaneous coronary intervention (PCI) and without clopidogrel pretreatment) a significant association was found between bleeding risk and variations in the gene coding for COX-1 (-842A>G and 50C>T) (both p=0.013). Six other investigated polymorphisms did not show any influence on bleeding complications. After controlling for potential bleeding confounders, the association between COX-1 gene polymorphisms (-842A>G and 50C>T) and bleeding risk remained statistically significant (both odds ratios 12.1, p=0.012). CONCLUSION Cyclooxygenase-1 -842G and 50T alleles significantly contribute to the risk of bleeding complications in patients undergoing elective CAG. Genetic testing is able to influence the safety of diagnostic cardiac catheterization in large numbers of low risk patients with borderline indications.

Abstract
INTRODUCTION Hereditary factors connected with inflammation and fibroproliferation may play important role in restenotic process after coronary stenting. Peroxisome proliferator-activated receptors (PPAR) and retinoic X receptors (RXR) regulate the transcription of crucial genes involved in the glucose and lipid metabolism, inflammation and cell differentiation. METHODS In our angiographic and clinical study we assessed the association of gene polymorphisms of L162V for PPAR-alpha, C161T for PPAR-gamma and A(39526)AA for RXR-alpha with the risk of restenosis and cardiac events after coronary stenting. Primary endpoint was diameter stenosis > or = 50% at follow-up angiography. Secondary endpoints were death, myocardial infarction and/or target lesion revascularisation at 12 months, and clinical restenosis. The results were adjusted for known predictors of restenosis. The genotypes were analysed by polymerase chains reaction (PCR) and restriction fragment length polymorphism (RFLP) methods. RESULTS Control angiography was performed in 477 of 565 patients (84.4%) with following restenosis rates in genotype subgroups: CC 29.0% vs GC/GG 22.6% (p = 0.33) in L162V, CC 29.9% vs TC/TT 24.6% (p = 0.24) in C161T and A/A 26.9% vs A/AA + AA/AA 35.0% (p = 0.14) in A(39526)AA polymorphisms. The T allele ofC161T polymorphism was associated with lower frequency of clinical restenosis (p = 0.015). CONCLUSION We could not find an association of L162V PPAR-alpha, C161T PPAR-gamma and A(39526)AA RXR-alpha gene polymorphisms with angiographic in-stent restenosis or major cardiac events. However, we found the relationship between C161T PPAR-gamma polymorphism and clinical restenosis deserving further study.

Abstract
Acute mesentery artery embolization is a rare diagnosis. In case of late recognition the mortality may reach up to 93%. Acute abdominal pain, vomitus, rapid and sudden bowel evacuation with or without blood are the typical symptoms of the disease. Unfortunately, the symptoms do not often correlate with clinical findings. Plain X-ray of abdomen or CT tomography may show no signs of intestinal ischaemia. The diagnostic method to choose is either spiral CT angiography or contrast angiography, respectively. The most common therapeutical approach is surgical revascularization but in selected cases it is feasible to perform local thrombolysis with a microcatheter placed directly into the occluded artery. Papaverin vasodilatation and intravenous anticoagulation are also justifiable, catheter aspiration and stent implantation have also been challenged. Our review is to provide a detailed up-to-date information about the issue and is an extensive follow-up of our recently published case report [Superior mesentery artery embolization as a complication of the primary angioplasty solved by local thrombolysis. Vnitr Lék 2008; 54(9): 871-875].

Abstract
Acute mesentery artery embolization is a rare complication of invasive catheterizations. The incidence is unknown. In case of late diagnosis the mortality may reach up to 93%. Acute abdominal pain, vomitus, rapid and sudden bowel evacuation with or without blood are the typical symptoms of the disease. Plain X-Rays of abdomen or CT tomography may show no signs of intestinal ischaemia. The diagnostic method to choose is either spiral CT angiography or contrast angiography, respectively. The most common therapeutical approach is surgical revascularization but in selected cases it is feasible to perform local thrombolysis with a microcatheter placed directly into the artery with embolus. We report a case of a man who was admitted with an acute myocardial infarction who underwent primary angioplasty with implantation ofa bare-metal stent. After the procedure he developed severe and progressive abdominal pain as a result of acute superior mesentery artery embolization. In this patient we performed a local thrombolysis with rt-PA (alteplase) with a great technical success and immediate pain relief, with no need of surgical revision. Our approach was concordant to recommendations cited in this article.

Abstract
INTRODUCTION Coronary artery disease (CAD) affects in lower percentage even younger individuals. This paper describes group of young patients aged 40 years or less with premature manifestation of CAD, including analysis of risk factors, severity of coronary arteries affection, management and follow-up lasting up to 7 years. PATIENTS AND METHODS There were 98 patients included retrospectively, in whom macroscopic affection of coronary arteries was diagnosed by coronary angiography within the years 2000-2007. 68 of the patients were indicated to coronary angiography urgently due to acute coronary syndrome (ACS), 44 of them due to acute myocardial infarction with ST elevations. The patients were called for further co-operation and 45 of them (45.9%) were re-examined completely and they will be observed prospectively. The results show overall good short-term prognosis of these patients and confirm importance of early invasive management and revascularisation. One-year mortality of the patients with ACS was 1.9%. 80% out of 45 completely re-examined patients have ejection fraction of left ventricle better than 50% and 84% ofthem is without any anginal symptoms. However, our results show inadequate secondary prevention in these patients. 15 patients (33%) still smoke, 20 (44%) is over-weighted. Only 22 patients (49%) had LDL-cholesterol level bellow 2.5 mmol/l and even only 15 patients (33%) had blood pressure below 130/80 mm Hg. CONCLUSIONS Management of these basic risk factors should improve even the long-term prognosis of our patients.

Abstract
BACKGROUND Abnormal heterogeneity of myocardial electrophysiologic processes increases the risk of malignant arrhythmias. The aim of the studywas to assess changes ofrepolarization homogeneity in patients after acute myocardial infarction (MI) using morphological parameters obtained from long-term 12-lead electrocardiographic recordings. METHODS In the group of 200 patients (45 females, 155 males) a long-term (10 minutes supine) 12-lead electrocardiographic recording (SEER MC, GE Medical) was performed 48-72 hours after acute myocardial infarction. The following parameters were calculated using experimental software: total cosine R to T (TCRT) and Twave residuum (TWR). The results were correlated with Q wave evolution and left ventricular ejection fraction (LVEF). RESULTS Distinguishing the MI type (Q vs nonQ) the following values were obtained: TCRT: 0.17 +/- 0.61 vs 0.16 +/- 0.49, p = 0.52, absolute TWR: 21,200 +/- 21,700 vs 25,700 +/- 29,300, p = 0.3, relative TWR: 0.0012 +/- 0.0017 vs 0.0017 +/- 0.0026, p = 0.28. Stratification according to LVEF (< or = 40% vs > 40%) led to: TCRT: -0.03 +/- 0.66 vs 0.25 +/- 0.54, p = 0.01, absolute TWR: 29,700 +/- 32,400 vs 21,300 +/- 21,500, p = 0.14, relative TWR: 0.0021 +/- 0.0047 vs 0.0013 +/- 0.0021, p = 0.48. CONCLUSION TCRT is a robust measurement of the spatial angle between the QRS complex and T wave loops which is related to LVEF. The results concerning TWR might indicate that this parameter is independent of LVEF, which needs to be confirmed in further analyses in a larger population.

Abstract
AIMS To compare two different clopidogrel regimens on the outcomes of patients undergoing elective coronary angiography (CAG)+/-ad hoc percutaneous coronary intervention (PCI). METHODS AND RESULTS Open-trial randomized 1028 patients with stable angina to group A ('non-selective'-clopidogrel 600 mg > 6 h before CAG; n = 513) or group B ('selective'-clopidogrel 600 mg in the cath-lab after CAG, only in case of PCI; n = 515). Combined primary endpoint was death/periprocedural myocardial infarction (MI)/stroke/re-intervention within 7 days. Secondary endpoints were troponin elevation and bleeding complications. Primary endpoint occurred in 0.8% group A patients vs. 1% group B (P = 0.749; 90% CI for the percentage difference -1.2-0.8). Periprocedural troponin elevation (> 3 x ULN) was detected in 2.6% group A vs. 3.3% group B (P = 0.475; 90% CI -2.5-1.0). Bleeding complications occurred in 3.5% group A patients vs. 1.4% group B (P = 0.025). After adjustment for covariates and factors that may influence the bleeding risk, patients in group A were shown to have more likely bleeding complications when compared with group B (OR = 3.03; 95% CI 1.14-8.10; P = 0.027). CONCLUSION High (600 mg) loading dose of clopidogrel before elective CAG increased the risk of minor bleeding complications, while the benefit on periprocedural infarction was not significant. Clopidogrel can be given safely in the catheterization laboratory between CAG and PCI in chronic stable angina patients.

Abstract
INTRODUCTION Increased values ofnatriuretic peptides are considered prognostically significant in normal population with respect to mortality and the incidence of cardiovascular events, regardless of the left ventricular function. The objective of the study is to point out the factors related to NT-proBNP values in patients without the heart failure syndrome and with normal left ventricular systolic function. METHODS The group consisted of 290 elective patients aged between 50 and 82, with the mean age of 62 years, of whom 47% were women. The enrolled patients were heamodynamically stable, without a history of MI, with a normal left ventricular systolic function and with the serum creatinine level < 150 micromol/l. On the same day, the following procedures were performed: left heart catheterisation, NT-proBNP sampling and echocardiographic examination. Diabetes mellitus, hypertension, coronary heart disease, body mass index, age, sex, left ventricular end-diastolic pressure and aortic pulse pressure were chosen as factors with possible impact on the level of NT-proBNP. We used echo parametres to assess the size of the left ventricle, the left ventricular mass index and the presence of left ventricular diastolic function. RESULTS The median of NT-proBNP was 110 pg/ml (min. 11; max. 1,943 pg/ml), and higher values were recorded for 116 (i.e. 40%) of the total number of patients. Based on the above-referred factors, a significant relation was demonstrated between NT-proBNP and age (p < 0.01), sex (p < .01), BMI (p = 0.03), left ventricular size (p = 0.02), left ventricular mass index (p = 0.01), and aortic pulse pressure (p < 0.01). CONCLUSION The study has shown that the level of NT-proBNP in patients does not solely depend on the haemodynamic status and left ventricular function, but is related to many other risk factors of cardiovascular mortality and morbidity.

BACKGROUND Ventricular repolarization abnormalities are associated with increased risk of sudden cardiac death in patients after myocardial infarction. The aim of this study is to assess QT dynamicity - QT/RR relationship - in patients after myocardial infarction and its contribution to risk stratification of sudden cardiac death. METHODS In a group of patients with diagnosis of acute myocardial infarction a long term ECG recording was performed 48-72 hours after myocardial infarction (MARS Unity Workstation, GE Medical Information Technologies). Patients with unstable circulation, artificial pulmonary ventilation, left bundle brach block, atrial fibrillation and paced rhythm were excluded. Analysis of QT dynamicity was performed by QT Guard software (GE Medical Information Technologies). QT/RR relationship is expressed by linear regression as QT = = aRR + b where "a" is termed "slope". RESULTS Assessment of QT dynamicity was possible in 215 ECG recordings. In 6-month follow-up 2 patients died and another was successfully resuscitated for primary ventricular fibrillation. Six-month mortality resp. mortality + resuscitation was 0.9 %, resp. 1.4 %. Therefore statistical evaluation was not possible. In the 3 mentioned individuals the slope values were 0.333, 0.249 and 0.342. CONCLUSIONS Mortality of up-to-date-treated patients after myocardial infarction is low. Therefore, in such patients it is not possible to assess QT dynamicity as a risk factor in midterm follow-up. Limitation of the method is the necessity of substantial selection of patients elegible for analysis and dependance on necessary equipment.

Abstract
INTRODUCTION The percentage of older population has significantly increased in the recent decades. Morphologic and functional changes of the cardiovascular system go together with ageing. The aim of the study should show the correlation between the age and left ventricular enddiastolic pressure (LVDEP) value. METHODS 106 patients of the age from 23 to 79 years without an organic heart disease and the history of hypertension underwent elective coronary angiography including left ventricle angiography between 1999 and 2002. LVEDP was obtained as an average value from 8 consecutive beats without extrasystoles. According to the relation between increased relative frequency of LVEDP and age patients were divided into two groups: 50 years and older (80 patients) and younger than 50 years (26 patients). RESULTS An average LVEDP value in older population versus younger population was 12.1 +/- 5.0 mm Hg vs 8.9 +/- 3.4 mm Hg, p < 0.05. Increased LVEDP in yonger population was found in only 11.5 % vs 46.2 % in older group, p < 0.01 and the LVEDP was age dependent, p < 0.05. CONCLUSIONS In compliance with about mentioned results we suppose that the age is a factor with impact to LVEDP value. LVEDP values > 12 mm Hg in older population may not be pathological and probably are due to the left ventricle diastolic dysfunction in consequence with ageing.

Abstract
BACKGROUND The primary success of the coronary artery reperfusion by primary coronary intervention (PCI) is almost angiographically assessed by TIMI flow score. The perfusion at a microvascular level can be inadequate despite the restoring of normal flow in the epicardial coronary artery. One of the options of successful reperfusion at a microvascular level is the measurement of ST-segment resolution (STR) after primary PCI. AIM The assessment of ST-segment resolution in patients indicated for primary PCI and the comparison with clinical data. METHODS The authors studied 149 patients (68.5 % men) with ST elevation acute myocardial infarction treated by primary PCI. The ECG was taken at the time of arriving patient at coronary unit and compared with ECG early after primary PCI. Patients were divided into 3 groups according to the grade of STR: with complete (> or = 70%), partial (30-69%) and none (< 30%) STR. The lead with maximal changes (STEmax) and sum of ST elevation (STEsum) were assessed. RESULTS 42 (28.2 %) patients had complete STR, 55 (36.9%) partial STR and 52 (34.9%) patients didn't achieve STR. STR was connected with better left ventricular ejection fraction, which was in group with complete STR 50% compared with 39.4% in group without STR (p < 0.0001). Patients with symptoms of heart failure on admission (Killip II-IV) had complete STR only in 4 cases (10%) compared with patients without heart failure (Killip I), where was complete STR in 38 (34.8%), (p = 0.003). There wasn't noted significant difference in STR at dependence on glycoprotein IIb/IIIa inhibitors administration. A normal or mildly slower coronary flow (TIMI 2, 3) was achieved in 146 patients (98%), 3 patients (2%) had inadequate coronary flow after primary PCI (TIMI 0, 1). CONCLUSIONS The evaluation of early ECG changes is simple method for the assessment of primary PCI success at the microvascular level. Our outcomes confirm a differences in achievement of optimal epicardial coronary flow and a perfusion at microvascular level.

Abstract
BACKGROUND Primary coronary angioplasty is at present accepted as the most effective reperfusion treatment strategy of the ST elevation acute myocardial infarction. The optimum approach appears to be combination of the interventional technique (mechanical reperfusion) with aggressive pharmacological treatment aimed at the platelets. Intravenous blockers of the glycoprotein receptors IIb/IIIa together with acetylsalicylic acid have the additive antiaggregant effect and are used more frequently as adjunctive therapy by coronary interventions in patients with acute coronary syndromes and the acute myocardial infarction. AIM The assessment of safety and effectiveness of the IIb/IIIa platelet blockers in patients indicated to primary coronary angioplasty. METHODS Since 1st January 2000 to 30th June 2001 the authors carried out the total of 912 coronary angioplasties in their cathlab, from which in 195 cases (21.4%) the primary angioplasty in acute ST elevation myocardial infarction was conducted. IIb/IIIa blockers were administered in the total of 53 cases (5.1% from the whole amount of coronary angioplasties), in 30 cases (15.4% from the total of 195 patients) of the primary coronary angioplasties, unlike the elective procedures, where these agents were given only in 9 patients (1.5% from the overall number of 621 coronary angioplasties) (p < 0.001). The authors in their work analyse the group of patients treated with primary coronary angioplasty with adjuvant treatment of IIb/IIIa platelet blockers. RESULTS In the stated period the IIb/IIIa platelet blockers were given to 30 patients at the age of 60.3 +/- 11.3 on average (70% were men). The most frequent risk factors were smoking, in 18 patients (60%), and hypertension, in 14 patients (40%). At least one coronary stent was implanted in 20 patients (66.7%). Abciximab was administered in 27 cases (90%) and eptifibatid in 5 cases (10%). Solely in 5 cases (16.7%) the agents were administered at least 10 minutes before the intervention and therefore preventively, and in 25 cases (83.3%) the administration was rescue. The reason for preventive administration was in 3 cases determination of the angiographically high-risk coronary artery disease and in 2 cases the thrombosis of another non-infarction related artery. The most frequent reason for the rescue use was in 6 cases (22.2%) slow-flow or no-reflow fenomena even after the mechanical obstacles and in 5 cases (18.5%) that were successfully treated with further dilatation, the acute in-stent thrombosis was observed. The infarct-related artery was most often the left anterior descending coronary artery, namely in 16 cases (54%). CONCLUSION IIb/IIIa platelet blockers in primary coronary angioplasty administered either preventively or as rescue therapy are highly effective, relatively safe and improve the effectiveness of mechanical reperfusion. The total in-hospital mortality of this group of patients was 10%.

Abstract
BACKGROUND Primary coronary angioplasty was accepted as a method of choice in the reperfusion treating strategy of the ST elevation acute myocardial infarction. Since 1995, when the very good results of the stent implantation in patients with acute myocardial infarction were published, there has been a general trend to more stenting also in the Czech Republic. AIM The analysis of the effectivety and safety of the coronary stent implantation in acute myocardial infarction. METHODS Prospective analysis of the patients with ST elevation acute myocardial infarction treated with primary coronary angioplasty with one coronary stent implantation at least in the period I/2000-XII/2000. RESULTS In the above mentioned period the authors carried out the total of 116 primary coronary angioplasties in 116 patients with ST elevation acute myocardial infarction. Balloon angioplasty only was done in 27 patients (23.3%) only, at least one stent was implanted in 89 patients (76.7%). The average procedure time was 58 +/- 27.2 mins, fluoroscopy 10.6 +/- 6.6 mins, sciagraphy 1.8 +/- 0.7 mins. Primary angiographical result was optimal in 82 cases (92.2%) with achieving TIMI flow 3, in 5 cases (5.6%) there was slower perfusion of the infarcted artery observed with TIMI flow 2 and in 2 cases (2.2%) the authors were unsuccessful with final TIMI flow 0-1. Coronary stents were implanted in 13 cases (13.8%) without predilatation as so called "direct stenting", in 19 cases (20.2%) the planned or "elective" stenting was done, in 47 cases (50%) the suboptimal result after balloon angioplasty only was the reason for stent implantation and in 15 cases (16%) it was rescue "bail-out" stenting in complications of the balloon angioplasty only or if the result after balloon angioplasty was unsuccessful. Primary angiographical success of the stented lesion was 100% and in 14 cases (15.7%) the abciximab as a representative of IIb/IIIa platelet blockers was given. Periprocedural complications (up-to 24 hours after the procedure) in the stented group of patients occurred in 2 cases (2.2%), further serious in-hospital cardiovascular complications occurred in another 4 cases (4.4%). The total of 5 patients (5.5%) died in the hospital, out of which 4 patients (4.4%) died due to the primary cardiogennic shock and 1 patient (1.1%) admitted in pulmonary oedema died due to the heart failure progression. Excluding patients primary in cardiogennic shock the in-hospital mortality was 1.2% only. Hospital mortality in the group of patients treated with primary balloon angioplasty only was 3.7% (1 patient). CONCLUSION At present the coronary artery stenting is safe and highly effective method in acute myocardial infarction treatment.
