Patterns of dyslipidemia in young patients with seronegative spondyloarthropathies without cardiovascular diseases.

OBJECTIVES: Patients with seronegative spondyloarthritis (SpA) - psoriatic arthritis (PsA) and ankylosing spondylitis (AS) - have a higher risk of cardiovascular morbidity and mortality. The aim of the present study was to evaluate the incidence and type of dyslipidemia, a potent atherosclerosis risk factor, in SpA patients. MATERIAL AND METHODS: It was a two-center, case-control study. Patients diagnosed with PsA and AS aged 23-60 years, with disease duration < 10 years, were enrolled. The inflammatory activity, serum levels of C-reactive protein (CRP) and lipid profile were evaluated in each patient. In patients > 40 years old, the 10-year risk of fatal cardiovascular disease (CVD), using Systematic Coronary Risk Evaluation (SCORE), was estimated. RESULTS: In total 79 patients with SpA were included in the study, with PsA diagnosed, n = 39 (mean age 45.1 ±9.6 years; 21, 53.9%, women), and with AS diagnosed, n = 40 (age 40.3 ±9.5; 12.3%, women), control group (CG): n = 88 (age 42.3 ±8.1; 42, 47.7% women). Based on the interview and laboratory tests, dyslipidemia was diagnosed in 19 (47.5%) patients with AS and in 28 (71.8%) patients with PsA. Most patients had hypercholesterolemia or mixed hyperlipidemia. Types of dyslipidemia were similar. In SpA patients (PsA and AS), the level of triglycerides (TG) and atherogenic index (AI) were significantly higher than in the CG, respectively TG in SpA: 116 (83-156) and in the CG: 91.2 (72.6-134.6) mg/dl, p = 0.0182; AI in SpA: 3.77 ±1.26 and in the CG: 2.58 ±1.27, p < 0.0001.The low-density cholesterol (LDL) level was significantly lower in SpA patients than in the CG, SpA: 109.1 ±29.4 vs. CG: 125.2 ±35.9 mg/dl, p = 0.0023. There was a strong negative correlation between CRP levels and HDL cholesterol levels in patients with PsA, rho = 0.42, p = 0.0132. Mean SCORE values were 2.33% in PsA patients and 2.38% in AS patients, which results in moderate 10-year risk of death from CVD. CONCLUSIONS: In young patients with spondyloarthropathies, inflammatory factors significantly influence dyslipidemia patterns, which result in higher TG and lower LDL cholesterol levels. In patients with PsA, dyslipidemia was diagnosed more often than in patients with AS.

Optimal medical therapy in patients with stable coronary artery disease in Poland: the ISCHEMIA trial experience.

Introduction: Optimal medical therapy (OMT) is the cornerstone of treatment for stable coronary disease with the ISCHEMIA trial showing similar outcomes using OMT with or without an initial invasive approach. Objectives: To describe OMT goal attainment in Polish ISCHEMIA participants compared with other countries. Patients and methods: Among 5179 trial participants, 333 were randomized in Poland. The median follow-up was 3.2 years. OMT targets were: not smoking, high-intensity statin therapy, low-density lipoprotein cholesterol (LDL-C) of less than 70 mg/dl, systolic blood pressure of less than 140 mm Hg, aspirin therapy, and ACEI / ARB, and ß-blocker therapy if indicated. Results: Compared with 36 other countries, at randomization, patients in Poland were older (67 [62­75] y vs 65 [58­71] y); P <⁠0.001), more often female (30% vs 22%; P = 0.002), with a longer history of angina (3 [1­9] y vs 1 [0­3] y; P <⁠0.001), and there were more cases of prior myocardial infarction (32% vs 18%; P <⁠0.01) and revascularization (PCI, 40% vs 19%; CABG, 11% vs 3%; P <⁠0.001 for both). The number of OMT goals attained increased from baseline to follow-up visits (5 [4­5] vs 6 [5­6]; P <⁠0.001) in Poland and other countries alike (P = 0.89 vs P = 0.14). In Poland, significant improvements were achieved regarding high-intensity statin therapy (27% vs 50%), LDL-C <⁠70 mg/dl (29% vs 65%), and systolic blood pressure of less than 140 mm Hg (63% vs 81%) (P <⁠0.001 for all), whereas not-smoking (89% vs 89%), aspirin (90% vs 88%), ACEI / ARB (93% vs 95%), and ß-blocker therapy (94% vs 90%) remained high. Conclusions: With regular surveillance and contemporary medical therapy, high OMT goal attainment was achievable among the participants of the ISCHEMIA trial in Poland relative to other countries. There is still room for improvement in LDL-C and blood pressure management.

Profile and treatment of chronic coronary syndromes in European Society of Cardiology member countries: The ESC EORP CICD-LT registry.

BACKGROUND: International guidelines recommend pharmacotherapy combinations for chronic coronary syndromes (CCSs) but medical management remains suboptimal. DESIGN: The CICD-LT registry is investigating short- and long-term outcomes and management in patients in European Society of Cardiology (ESC) member countries, in a longitudinal ESC EURObservational Research Programme aimed at improving CCS management. METHODS: Between 1 May 2015 and 31 July 2018, 9174 patients with previous ST-elevation myocardial infarction (STEMI), non-STEMI or coronary revascularisation, or other CCS, were recruited during a routine ambulatory visit or elective revascularisation procedure. Baseline clinical data were recorded and prescribed medications analysed at initial contact and discharge, and according to patient gender and age (<75 vs. ≥75 years). RESULTS: Poorly controlled cardiovascular risk factors, including current smoking (18.5%), obesity (33.9%), diabetes (25.8%), raised low-density lipoprotein cholesterol (73.3%) and persistent hypertension (24.7%), were common across all cohorts. At ambulatory visit or admission, the guidelines-recommended combination of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, beta-blocker, aspirin, statin and any antiplatelet agent was prescribed to 57.8% of patients with STEMI/NSTEMI. Differences in prescribing rates, including for combination therapies, were observed based on age and gender and persisted after adjustment for demographic factors. CONCLUSIONS: Cardiovascular risk factors were common in contemporary CCS patients and secondary prevention prescribing was suboptimal. Patients aged ≥75 years and, to some extent, female patients were less likely to receive guidelines-recommended drug combinations than younger and male patients. One- and two-year follow-up will study prescribing changes and associations between baseline characteristics/prescribing and subsequent clinical outcomes.

Initial Invasive or Conservative Strategy for Stable Coronary Disease.

BACKGROUND: Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain. METHODS: We randomly assigned 5179 patients with moderate or severe ischemia to an initial invasive strategy (angiography and revascularization when feasible) and medical therapy or to an initial conservative strategy of medical therapy alone and angiography if medical therapy failed. The primary outcome was a composite of death from cardiovascular causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. A key secondary outcome was death from cardiovascular causes or myocardial infarction. RESULTS: Over a median of 3.2 years, 318 primary outcome events occurred in the invasive-strategy group and 352 occurred in the conservative-strategy group. At 6 months, the cumulative event rate was 5.3% in the invasive-strategy group and 3.4% in the conservative-strategy group (difference, 1.9 percentage points; 95% confidence interval [CI], 0.8 to 3.0); at 5 years, the cumulative event rate was 16.4% and 18.2%, respectively (difference, -1.8 percentage points; 95% CI, -4.7 to 1.0). Results were similar with respect to the key secondary outcome. The incidence of the primary outcome was sensitive to the definition of myocardial infarction; a secondary analysis yielded more procedural myocardial infarctions of uncertain clinical importance. There were 145 deaths in the invasive-strategy group and 144 deaths in the conservative-strategy group (hazard ratio, 1.05; 95% CI, 0.83 to 1.32). CONCLUSIONS: Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used.

The long term risk of lead failure in patients with cardiovascular implantable electronic devices undergoing catheter ablation.

Objectives. The aim of the study was to assess the long-term influence of catheter ablation (CA) of different arrhythmias on cardiovascular implantable electronic devices (CIED) endocardial leads durability. Design. This was a retrospective case-control study. Ablation protocols and in- or outpatient medical records were reviewed to identify and extract data on adult patients with CIED undergoing a CA. A cohort of patients with hypertrophic cardiomyopathy and implantable cardioverter-defibrillators (ICD) served as a historical control group. The primary endpoint was the diagnosis of lead damage defined as permanent loss of proper function demanding replacement or removal. Results. Among 145 patients n = 177 catheter ablations were performed. Patients' mean age was 66.4 ± 10.5, 66.1% had an ICD or ICD with cardiac resynchronization function (CRT-D), 18.1% had >1 CA. During median 812 days [IQR 381-1588] of follow-up, there were 11 (6.2%) cases of lead damage in the examined and 13 cases (13%) in the control group, p = 0.054. None of the technical aspects of the CA (indication, type of catheter, transseptal sheath) influenced the primary outcome. Both the number of leads and observation time after CA were significantly related to the risk of endocardial lead damage. Conclusion. This study did not find any significant influence of CA on the long-term durability of CIED endocardial leads. Reported risk factors were consistent with general population of CIED patients.

Intravenous antazoline, a first-generation antihistaminic drug with antiarrhythmic properties, is a suitable agent for pharmacological cardioversion of atrial fibrillation induced during pulmonary vein isolation due to the lack of influence on atrio-venous conduction and high clinical effectiveness (AntaEP Study).

AIMS: Antazoline is a first-generation antihistaminic drug used primarily in eye drop formulations. When administered intravenously, antazoline displays antiarrhythmic properties resulting in a rapid conversion of recent-onset atrial fibrillation (AF) to sinus rhythm (SR). The aim of the study was to assess the influence of antazoline on atrio-venous conduction and other electrophysiological parameters in patients undergoing AF ablation. METHODS: An experimental prospective study. Patients scheduled for the first-time AF ablation, in SR and not on amiodarone were enrolled. Atrio-venous conduction assessment and invasive electrophysiological study (EPS) were performed before and after intravenous administration of 250 mg of antazoline. In case of AF induction during EPS, antazoline was administered until conversion to SR or a cumulative dose of 300 mg. RESULTS: We enrolled 14 patients: 13 (93%) men, mean age 63.4 (59.9-66.8) years, mean CHA2 DS2 -VASc score 1.6 (1.0-2.2). Antazoline was administered in a mean dose 257.1 (246.7-267.6) mg. Pulmonary vein potentials and atrial capture during pulmonary vein stimulation were present before and after the administration of antazoline. Wenckebach point and atrial conduction times did not change significantly, but atrio-ventricular node effective refractory period improved-324.7 (275.9-373.5) ms vs 284.3 (256.2-312.4) ms, P = 0.02. Antazoline was effective in all 5 (100%) cases of AF induction during EPS. There were no serious adverse events. CONCLUSION: Due to the lack of influence on atrio-venous conduction and high clinical effectiveness, antazoline may be suitable for pharmacological cardioversion of AF occurring during AF ablation.

Increased prevalence of subclinical coronary atherosclerosis in young patients with ankylosing spondylitis.

Introduction There is substantial evidence that spondyloarthropathies, such as ankylosing spondylitis (AS) and psoriatic arthritis (PsA), may increase cardiovascular risk. Objectives The study aimed to compare development of atherosclerotic lesions in coronary arteries between patients with AS and individuals without rheumatic dise ases. Patients and methods A total of 37 adult patients with AS (mean [SD] age, 40.4 [9.6] years; men, 26 [70.3%]), with disease duration of less than 10 years were enrolled. The control group consisted of 76 participants without rheumatic diseases. Controls were matched for age, sex, history of hypertension, dyslipidemia, and smoking status. Coronary computed tomography angiography was performed in both groups. Results Atherosclerotic lesions in the coronary arteries were present in 18 patients (48.7%) with AS compared with 20 controls (26.3%) (P = 0.02). Univariate analysis performed in the AS group demonstrated an association between the presence of lesions and age (P = 0.02), hypertension (P = 0.003), and dyslipidemia (P = 0.001). The multivariable logistic regression analysis showed a significant association between coronary atherosclerosis and hypertension (P = 0.008) and with dyslipidemia (P = 0.001). The average plaque burden was higher in patients with AS than in controls (mean [SD], 42.2% [4.7%] vs 36.5% [3.1%], P <0.0001). Conclusions Atherosclerotic plaques in the coronary arteries were significantly more prevalent in patients with AS. A strong association was demonstrated between atherosclerotic lesions and age, hypertension, and dyslipidemia. Our results confirm the need for cardiovascular risk assessment in patients with AS and cardiovascular prevention, if indicated.

Risk factors predisposing to acute coronary syndromes in young women ≤45 years of age.

BACKGROUND: Acute coronary syndromes (ACS) are rare in young women. The purpose of this study was to characterize risk factors (RF) predisposing to ACS in young women and evaluate possible age-related differences. METHODS AND RESULTS: We studied 1941 young women with ACS aged ≤45 years (≤45ACS) from the PL-ACS registry and compared them with two control groups: 4275 women aged 63-64 years with ACS (63-64ACS) from the PL-ACS registry and 1170 young healthy women aged ≤45 years (≤45H) without confirmed coronary artery disease (CAD), from two national, representative, cross-sectional population health surveys, NATPOL 2011 and WOBASZ. The prevalence of major RF in these three groups was as follows, respectively: (≤45 ACS vs. 63-64ACS vs. ≤45H, for all P < 0.0001): hypertension 49.8% vs. 78.1% vs. 16.8%; hypercholesterolemia 36.1% vs. 44.3% vs. 12.9%; obesity 22.3% vs. 28.1% vs. 15.6%; diabetes 10.6% vs. 29.9% vs. 1.8% and smoking 48.7% vs. 22.2% vs. 39%. Healthy women had the lowest number of major RF (1.7 ±â€¯1.2 vs. 2.0 ±â€¯1.1 vs. 1.1 ±â€¯1.0). No RF was found in 16.7% vs. 8.2% vs. 34.4% women, respectively. Independent predictors of ACS in the ≤45ACS group included diabetes [odds ratio (OR) 6.66, 95% confidence interval (CI) 3.47-12.74]*, hypertension (OR 4.30, 95% CI 3.42-5.38)*, hypercholesterolemia (OR 3.45; 95% CI 2.60-4.29)*, and smoking (OR 1.63, 95% CI 1.34-1.98)*, *(P < 0.0001 for all). CONCLUSIONS: The prevalence of risk factors for acute coronary syndromes in young women with ACS is different to those in healthy women and to those in older women. The prevalence of smoking was higher. The strongest predictor of ACS in women ≤45 years of age was diabetes, with a 6-fold increase in risk. There is still need to improve the cardio-vascular primary prevention and health promotion in the population of young women.

Sex Difference in Patients With Ischemic Heart Failure Undergoing Surgical Revascularization: Results From the STICH Trial (Surgical Treatment for Ischemic Heart Failure).

BACKGROUND: Female sex is conventionally considered a risk factor for coronary artery bypass grafting (CABG) and has been included as a poor prognostic factor in multiple cardiac operative risk evaluation scores. We aimed to investigate the association of sex and the long-term benefit of CABG in patients with ischemic left ventricular dysfunction enrolled in the prospective STICH trial (Surgical Treatment for Ischemic Heart Failure Study). METHODS: The STICH trial randomized 1212 patients (148 [12%] women and 1064 [88%] men) with coronary artery disease and left ventricular ejection fraction ≤35% to CABG+medical therapy (MED) versus MED alone. Long-term (10-year) outcomes with each treatment were compared according to sex. RESULTS: At baseline, women were older (63.4 versus 59.3 years; P=0.016) with higher body mass index (27.9 versus 26.7 kg/m2; P=0.001). Women had more coronary artery disease risk factors (diabetes mellitus, 55.4% versus 37.2%; hypertension, 70.9% versus 58.6%; hyperlipidemia, 70.3% versus 58.9%) except for smoking (13.5% versus 21.8%) and had lower rates of prior CABG (0% versus 3.4%; all P<0.05) than men. Moreover, women had higher New York Heart Association class (class III/IV, 66.2% versus 57.0%), lower 6-minute walk capacity (300 versus 350 m), and lower Kansas City Cardiomyopathy Questionnaire overall summary scores (51 versus 63; all P<0.05). Over 10 years of follow-up, all-cause mortality (49.0% versus 65.8%; adjusted hazard ratio, 0.67; 95% confidence interval, 0.52-0.86; P=0.002) and cardiovascular mortality (34.3% versus 52.3%; adjusted hazard ratio, 0.65; 95% confidence interval, 0.48-0.89; P=0.006) were significantly lower in women compared with men. With randomization to CABG+MED versus MED treatment, there was no significant interaction between sex and treatment group in all-cause mortality, cardiovascular mortality, or the composite of all-cause mortality or cardiovascular hospitalization (all P>0.05). In addition, surgical deaths were not statistically different (1.5% versus 5.1%; P=0.187) between sexes among patients randomized to CABG per protocol as initial treatment. CONCLUSIONS: Sex is not associated with the effect of CABG+MED versus MED on all-cause mortality, cardiovascular mortality, the composite of death or cardiovascular hospitalization, or surgical deaths in patients with ischemic left ventricular dysfunction. Thus, sex should not influence treatment decisions about CABG in these patients. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov. Unique identifier: NCT00023595.

"Buddy wire" for facilitation of femoral venous access for cryoablation: a preliminary report.

BACKGROUND: Some electrophysiological techniques, such as balloon cryoablation, involve the use of steerable sheaths of large diameter (outer diameter 15 Fr or more). Their introduction to the femoral vein may be difficult, especially in patients who have had numerous venipunctures in this area. AIM: The authors describe a modification of typical venous access with the use of a "buddy wire" technique, facilitating the insertion of the cryoablation sheaths to the femoral vein. METHODS: A case-control study. The study involved a retrospective analysis of 27 consecutive procedures of balloon cryoablation of pulmonary veins performed in 2015 by the first author, compared to 23 consecutive procedures of balloon cryoablation performed in 2014 without a "buddy wire" technique. The study and control groups did not vary significantly. There were 11 women in both groups. The average age of the patients was 55.9 years. The "buddy wire" technique was the only difference in procedure performance between the control and study groups. In the study group a short introducer was inserted through a puncture of the right femoral vein, and then two wires were introduced through it. One of them was secured, so that it could not move, while the other served as a typical trans-septal puncture monitored with the use of X-ray. The standard trans-septal sheet was replaced with a 15 Fr steerable sheath, inserted through the same puncture site next to the secured "buddy wire". The short wire was then removed from the femoral vein. Typical balloon cryoablation of pulmonary veins was performed. After the end of the procedure, the puncture site was secured with a haemostatic suture for 12-18 h. RESULTS: Femoral access with a 15 Fr steerable sheath and cryoablation were safely performed in all patients in the study group and in 22 out of 23 in the control group (100% vs. 95.6%, p = NS). Pulmonary vein isolation in one patient was performed using another technique. No damage to steerable sheaths was observed. There were no vascular complications requiring extended hospitalisation, blood transfusion, or surgical interventions in either group. The "door-to-door" time of the procedures ranged from 2 h 32 min on average in the study group to 2 h 43 min on average in the control group (p = NS). There was significant reduction in fluoroscopy time: 7 min 15 s on average from 11 min 25 s (p = 0.0009). CONCLUSIONS: The use of the "buddy wire" technique may lead to significant reduction in fluoroscopy time during cryoablation of pulmonary veins by facilitating the insertion of the steerable sheaths to the femoral vein.

New diagnostic pathways urgently needed. Protocol of PET Guidance I pilot study: positron emission tomography in suspected cardiac implantable electronic device-related infection.

BACKGROUND: Cardiovascular implantable electronic device (CIED) infection is a complication of increasing incidence. We present a protocol of an observational case control clinical trial "Positron Emission Tomography Combined With Computed Tomography (PET CT) in Suspected Cardiac Implantable Electronic Device Infection, a Pilot Study - PET Guidance I" (NCT02196753). AIM: The aim of this observational clinical trial is to assess and standardise diagnostic algorithms for CIED infections (lead-dependent infective endocarditis, generator pocket infection, fever of unknown origin) with PET CT in Poland. METHODS AND RESULTS: Study group will consist of 20 patients with initial diagnosis of CIED-related infection paired with a control group of 20 patients with implanted CIEDs, who underwent PET CT due to other non-infectious indications and have no data for infectious process in follow-up. All patients included in the study will undergo standard diagnostic pro-cess. Conventional/standard diagnostic and therapeutic process will consist of: medical interview, physical examination, laboratory tests, blood cultures; imaging studies: echocardiography: transthoracic (TTE), and, if there are no contraindications transoesophageal, computed tomography scan for pulmonary embolism if indicated; if there are abnormalities in other systems, decisions concerning further diagnostics will be made at the physician's discretion. As well as standard diagnostic procedures, patients will undergo whole body PET CT scan to localise infection or inflammation. Diagnosis and therapeutic decision will be obtained from the Study Committee. Follow-up will be held within six months with control visits at three and six months. During each follow-up visit, all patients will undergo laboratory tests, two blood cultures collected 1 h apart, and TTE. In case of actual clinical suspicion of infective endocarditis or local generator pocket infection, patients will be referred for further diagnostics. Endpoints for the results assessment - primary endpoints are to standardise PET CT in the diagnostic process: sensitivity, specificity, positive predictive value, and negative predictive value of the diagnosis made by PET CT; secondary endpoints are: assessment of usefulness of PET CT for detection of remote infective complications (metastatic abscesses, infected pulmonary emboli), incidence of particular localisations of infection, influence of PET CT on therapeutic decision: confirmation or change of decision based on PET CT, safety and complications of diagnostic process of CIED-related infections with PET CT. CONCLUSIONS: Evaluation of PET CT use for device-related infections in a case control study may be conclusive and improve diagnostic pathway.

EURObservational Research Programme: the Chronic Ischaemic Cardiovascular Disease Registry: Pilot phase (CICD-PILOT).

AIMS: Chronic ischaemic cardiovascular disease (CICD) is a major cause of mortality and morbidity worldwide. The primary objective of the CICD-Pilot registry was to describe the clinical characteristics and management modalities across Europe in a broad spectrum of patients with CICD. METHODS AND RESULTS: The CICD-Pilot registry is an international prospective observational longitudinal registry, conducted in 100 centres from 10 countries selected to reflect the diversity of health systems and care attitudes across Europe. From April 2013 to December 2014, 2420 consecutive CICD patients with non-ST-elevation acute coronary syndrome (n = 755) and chronic stable coronary artery disease (n = 1464), of whom 933 (63.7%) were planned for elective coronary intervention, or with peripheral artery disease (PAD) (n = 201), were enrolled (30.5% female patients). Mean age was 66.6 ± 10.9 years. The following risk factors were reported: smoking 54.6%, diabetes mellitus 29.2%, hypertension 82.6%, and hypercholesterolaemia 74.1%. Assessment of cardiac function was made in 69.5% and an exercise stress test in 21.2% during/within 1 year preceding admission. New stress imaging modalities were applied in a minority of patients. A marked increase was observed at discharge in the rate of prescription of angiotensin-converting enzyme-inhibitors/angiotensin receptor blockers (82.8%), beta-blockers (80.2%), statins (92.7%), aspirin (90.3%), and clopidogrel (66.8%). Marked differences in clinical profile and treatment modalities were observed across the four cohorts. CONCLUSION: The CICD-Pilot registry suggests that implementation of guideline-recommended therapies has improved since the previous surveys but that important heterogeneity exists in the clinical profile and treatment modalities in the different cohorts of patients enrolled with a broad spectrum of CICDs.

Long-term temporary pacing with an active fixation lead.

BACKGROUND: Ensuring a haemodynamically effective cardiac rhythm is a challenge in patients waiting for pacemaker reimplantation after transcutaneous lead extraction due to an infection of the implanted system. AIM: The authors report a retrospective analysis of temporary pacing with an active fixation lead (AFTP) connected to an externalised pacemaker in patients after transvenous lead extraction (TLE) due to an infection. METHODS: AFTP was used in 34 patients (12 women) aged from 38 to 88 years (mean 67.5 years). This represented 24.5% of the population of patients undergoing TLE due to infective indications. In 32 cases, the indication for temporary pacing was atrioventricular block, and in 2 patients sick sinus syndrome. The lead was implanted via the internal jugular vein puncture into the right ventricle in 33 cases and into the right atrium in 1 case. Leads were secured to the skin and attached to externalized pacemakers. RESULTS: AFTP was used for 4 to 26 days (average 14.5 days). Re-implantation was performed in 29 patients (85.3% of the study group). There was no early infection recurrence. Three patients died during AFTP (8.8% of the study group), including two due to septic shock, and a cardiac arrest due to pulseless electrical activity in another patient. CONCLUSIONS: Temporary pacing with an active fixation lead is an effective and safe method to ensure a hemodynamically stable heart rhythm for a period ranging from a few to several days after the surgery in patients after transcutaneous lead extraction due to infective indications.

Prospective assessment of cytokine IL-15 activity in patients with refractory atrial fibrillation episodes.

AIMS: Inflammatory state is considered a risk factor of atrial fibrillation (AF) occurrence. The aim of this study was a prospective evaluation of the inflammation parameters in patients with different forms of AF without structural heart disease. METHODS AND RESULTS: One hundred fifty-eight patients with paroxysmal/persistent AF (87; 55.1% men, mean age 65.8±9.6 years) without structural heart disease were enrolled in the study. Inflammatory parameters: WBC, ESR, hs-CRP, IL-6, IL-15 and TNF-alpha were measured at baseline and after one year follow-up. Despite frequent AF episodes median values of WBC, ESR and C-reactive protein at baseline and after follow up were within normal ranges. There were no significant differences between WBC, ESR and hs-CRP regarding AF types. In patients who developed permanent AF form (n=14) hs-CRP concentrations were higher at baseline: 0.35 (IQR1: 0.09 IQR: 0.61) vs 0.15 (IQR1: 0.07 IQR: 0.29), p<0.01. Nevertheless, after one year's observation these differences were not significant. Among all cytokines were studied only IL-15 was significantly correlated with the number of AF episodes (r=0.26), mean (IQ1-IQ3): 10 (3-30) vs 60 (50-100), p=0.00681. CONCLUSION: Basic inflammatory markers were not changed in patients with refractory atrial fibrillation episodes in prospective one year's observation. Only cytokine IL-15 was correlated to numbers of AF episodes. It's potential role as a marker of arrhythmia deserves further evaluation.

Osteoprotegerin in patients with degenerative aortic stenosis and preserved left-ventricular ejection fraction.

OBJECTIVES: The aim of the present study was to evaluate value of osteoprotegerin (OPG) in patients with degenerative aortic stenosis and preserved left-ventricular ejection fraction. METHODS: We have prospectively followed 70 patients with aortic stenosis (mean aortic gradient ≥15 mmHg) and preserved left-ventricular ejection fraction for 1 year. In all patients, echocardiography and blood tests (OPG, lipids, high-sensitivity C-reactive protein) were performed at baseline and after 1 year of follow-up. Detailed medical history including atherosclerotic risk factors was obtained. The control group consisted of 20 healthy individuals with normal echocardiographic findings. Rapid progression of aortic stenosis was defined as more than 7 mmHg increase in mean aortic gradient per year. RESULTS: Osteoprotegerin concentrations were significantly higher in patients with aortic stenosis (P < 0.0001) and correlated with the degree of aortic stenosis. In multivariable regression model analysis, age (ß = 0.015, P < 0.0001), mean aortic gradient (ß = 0.04, P = 0.0078) and presence of coronary artery disease (ß = 0.111, P = 0.0408) were the only independent determinants of plasma OPG concentrations. There was no association between OPG concentrations and coronary artery disease risk factors: male sex, smoking, hypertension and hypercholesterolemia. Concentrations of high-sensitivity C-reactive protein correlated positively with OPG levels only in nonsurgical patients (with lower degree of stenosis) (r = 0.34, P = 0.01). Aortic stenosis progression was related to body mass, diabetes, triglyceride concentrations, metabolic syndrome and left-ventricular systolic volume. In multivariate analysis, only metabolic syndrome was an independent predictor of aortic stenosis progression. CONCLUSION: Osteoprotegerin concentrations are linked to the presence and severity of aortic stenosis. Metabolic syndrome was the only independent predictor of degenerative aortic stenosis progression.

The use of 1.5 T magnetic resonance imaging for therapeutic decisions in patients with cardiac implantable electronic devices and significant neurological, neurosurgical and neuro-oncology diagnostic indications.

UNLABELLED: Between September 2009 and May 2014 the classification of 36 patients with cardiac implantable electronic devices (CIEDs) in terms of the feasibility of MRI scanning due to strong clinical indications was carried out. Finally MRI examinations were performed in 20 patients, of whom 27 studies were conducted and a total number of 35 anatomical regions were scanned. Neurological, neurosurgical and neuro-oncology indications for MRI were reported in 19 patients (95%) in whom 26 MRI studies (96.3%) were performed, and 34 anatomical regions (97.1%) were scanned. One patient had indications for MRI in the field of cardiology. Medical information obtained from 27 MRI studies allowed decisions to be made regarding the treatment in all patients. After 8 studies (29.6%), patients were classified into 9 different neurosurgical procedures. In the case of the remaining 19 studies (70.4%), there were no indications for surgical treatment and the decisions to implement conservative treatment were made. There were no complications related to the implanted CIEDs observed: neither immediate nor in the follow-up.

Lead extraction: The road to successful cardiac resynchronization therapy.

BACKGROUND: Still increasing life expectancy in patients with implanted devices and large number of leads more and more often induce the need to cure the treatment complications or to change especially to cardiac resynchronization therapy (CRT). In order to prevent further complications, the possibility of damaged or redundant leads extraction should be taken into consideration. The aim of the paper was to assess the effectiveness and safety of transvenous lead extraction (TLE) with co-implantation of resynchronization systems. METHODS AND RESULTS: Between 2008 and March 2013, the system removal with TLE was conducted in 246 patients. In 38 patients (11 women, 28.9%), aged 43-79 (mean 65 years), it was combined with co-implantation of CRT-pacemaker or defibrillator (CRT-P/D). Indications for TLE covered: lead failure in 21 (55.3%) patients, redundant leads in 6 (15.8%), and the occluded venous system in 7 (18.4%). The up-grade of the pacemaker or defibrillator system to CRT-D was performed in 19 cases, CRT-P/D revision in next 19. Together 32 defibrillation leads and 42 pacing leads (27 left ventricular leads, and 1 epicardial lead) were implanted. The intended clinical target--an effective resynchronization therapy--was obtained in all patients. There was no case of death or severe complications. In 2 cases of venous occlusion, the implantation on the contralateral side was required. CONCLUSIONS: TLE enables effective resynchronization therapy also in the case of the presence of too many leads, occlusion of the venous system or lead failure. Significant technical problems can occur especially in patients with venous system occlusion.

Extent of coronary and myocardial disease and benefit from surgical revascularization in ischemic LV dysfunction [Corrected].

BACKGROUND: Patients with ischemic left ventricular dysfunction have higher operative risk with coronary artery bypass graft surgery (CABG). However, those whose early risk is surpassed by subsequent survival benefit have not been identified. OBJECTIVES: This study sought to examine the impact of anatomic variables associated with poor prognosis on the effect of CABG in ischemic cardiomyopathy. METHODS: All 1,212 patients in the STICH (Surgical Treatment of IsChemic Heart failure) surgical revascularization trial were included. Patients had coronary artery disease (CAD) and ejection fraction (EF) of ≤35% and were randomized to receive CABG plus medical therapy or optimal medical therapy (OMT) alone. This study focused on 3 prognostic factors: presence of 3-vessel CAD, EF below the median (27%), and end-systolic volume index (ESVI) above the median (79 ml/m(2)). Patients were categorized as having 0 to 1 or 2 to 3 of these factors. RESULTS: Patients with 2 to 3 prognostic factors (n = 636) had reduced mortality with CABG compared with those who received OMT (hazard ratio [HR]: 0.71; 95% confidence interval [CI]: 0.56 to 0.89; p = 0.004); CABG had no such effect in patients with 0 to 1 factor (HR: 1.08; 95% CI: 0.81 to 1.44; p = 0.591). There was a significant interaction between the number of factors and the effect of CABG on mortality (p = 0.022). Although 30-day risk with CABG was higher, a net beneficial effect of CABG relative to OMT was observed at >2 years in patients with 2 to 3 factors (HR: 0.53; 95% CI: 0.37 to 0.75; p<0.001) but not in those with 0 to 1 factor (HR: 0.88; 95% CI: 0.59 to 1.31; p = 0.535). CONCLUSIONS: Patients with more advanced ischemic cardiomyopathy receive greater benefit from CABG. This supports the indication for surgical revascularization in patients with more extensive CAD and worse myocardial dysfunction and remodeling.
