RESUMO
AIM: We investigated if the baseline value of mid-regional pro-atrial natriuretic peptide (NP), N-terminal pro-B-type NP and copeptin may be helpful in optimizing ß-blocker uptitration in elderly patients with heart failure. PATIENTS & METHODS: According to the biomarkers' levels, 457 patients were divided into three subgroups and compared with each other at baseline and 3 months after. RESULTS: All mid-regional pro-atrial NP and N-terminal pro-B-type NP subgroups had significant amelioration of left ventricle ejection fraction and New York Heart Association (NYHA) class after 3 months of ß-blocker uptitration (p < 0.001). More prominent improvement of left ventricle ejection fraction and New York Heart Association class was observed in subgroups with lower versus higher NPs levels. CONCLUSION: NPs levels, unlike copeptin levels, might be useful tool for objective selection of elderly heart failure patients who could have the greatest benefit of forced uptitration.

OBJECTIVES: Bundle branch blocks (BBB)-related mechanical dyssynchrony and dispersion may improve patient selection for device therapy, but their effect on the natural history of this patient population is unknown. METHODS: A total of 155 patients with LVEF ≤ 35% and BBB, not treated with device therapy, were included. Mechanical dyssynchrony was defined as the presence of either septal flash or apical rocking. Contraction duration was assessed as time interval from the electrocardiographic R-(Q-)wave to peak longitudinal strain in each of 17 left ventricular segments. Mechanical dispersion was defined as either the standard deviation of all time intervals (dispersionSD) or as the difference between the longest and shortest time intervals (dispersiondelta). Patients were followed for cardiac mortality during a median period of 33 months. RESULTS: Mechanical dyssynchrony was not associated with survival. More pronounced mechanical dispersiondelta was found in patients with dyssynchrony than in those without. In the multivariate regression analysis, patients' functional class, diabetes mellitus and dispersiondelta were independently associated with mortality. CONCLUSIONS: Mechanical dispersion, but not dyssynchrony, was independently associated with mortality and it may be useful for risk stratification of patients with heart failure (HF) and BBB. Key Messages Mechanical dispersion, measured by strain echocardiography, is associated with poor outcome in heart failure with a severely depressed left ventricular function and bundle branch blocks. Mechanical dispersion may be useful for risk stratification of patients with heart failure and bundle branch blocks.

PURPOSE: We aimed at evaluating androgen status (serum testosterone [TT] and estimated free testosterone [eFT]) and its determinants in non-diabetic elderly men with heart failure (HF). Additionally, we investigated its associations with body composition and long-term survival. METHODS: Seventy three non-diabetic men with HF and 20 healthy men aged over 55 years were studied. Echocardiography, 6-min walk test, grip strength, body composition measurement by DEXA method were performed. TT, sex hormone binding globulin, NT-proBNP, and adipokines (adiponectin and leptin) were measured. All-cause mortality was evaluated at six years of follow-up. RESULTS: Androgen status (TT, eFT) was similar in elderly men with HF compared to healthy controls (4.79 ± 1.65 vs. 4.45 ± 1.68 ng/ml and 0.409 ± 0.277 vs. 0.350 ± 0.204 nmol/l, respectively). In HF patients, TT was positively associated with NT-proBNP (r= 0.371, p = 0.001) and adiponectin levels (r = 0.349, p = 0.002), while inverse association was noted with fat mass (r = -0.413, p < 0.001). TT and eFT were independently determined by age, total fat mass and adiponectin levels in elderly men with HF (p < 0.05 for all). Androgen status was not predictor for all-cause mortality at six years of follow-up. CONCLUSIONS: In non-diabetic men with HF, androgen status is not altered and is not predictive of long-term outcome.

Some patients with unstable angina and critical stenosis of the left anterior descending coronary artery (LAD) present with Wellens syndrome (WS), i.e., inverted or biphasic T-waves in the anterior precordial leads. We assessed clinical, angiographic, electro- and echocardiographic characteristic of patients with WS. In this retrospective study, clinical, angiographic, electro- and echocardiographic characteristic of 35 patients with WS were compared to 57 patients with critical LAD stenosis and normal resting electrocardiogram (ECG), and 45 subjects with normal coronary angiogram. QTc dispersion was measured from the 12-lead ECG as the difference between longest and shortest QTc intervals. Mechanical dispersion was defined as the time difference between the longest and shortest contraction durations which were measured as the time from the first deflection of the QRS complex to maximum myocardial shortening of each 18 segmental longitudinal strain curves derived by speckle tracking echocardiography. There were no significant differences in the complexity and location of the LAD lesion, anterograde and collateral flow in LAD and coronary artery dominance between patients with WS and normal ECG (P > 0.05, for all). Patients with WS had lower global longitudinal strain (GLS) and more pronounced both QTc and myocardial mechanical dispersion than patients with critical LAD stenosis and normal ECG, and control subjects (P < 0.05). T-wave changes in patients with WS are associated with more profound regional myocardial dysfunction and increased QTc and myocardial mechanical dispersion. Similar angiographic characteristics of the LAD lesion were seen in patients with WS and normal ECG.

INTRODUCTION: Data on effects of thrombus aspiration on left ventricular diastolic function in ST-elevation myocardial infarction (STEMI) population are scarce. OBJECTIVE: We sought to compare echocardiographic indices of the diastolic function and outcomes in STEMI patients treated with and without manual thrombus aspiration, in an academic, high-volume percutaneous coronary intervention (PCI) center. METHODS: A total of 433 consecutive patients who underwent primary PCI in 2011-2012 were enrolled in the study. Patients were not eligible for the study if they already suffered a myocardial infarction, had been previously revascularized, received thrombolytics, presented with cardiogenic shock, had significant valvular disease, atrial fibrillation or had previously implanted pacemaker. Comprehensive echocardiogram was performed within 48 hours. During follow-up patients'status was assessed by an office visit or telephone interview. RESULTS: Patients treated with thrombus aspiration (TA+, n=216) had similar baseline characteristics as those without thrombus aspiration (TA-, n = 217). Groups had similar total ischemic time (319 ± 276 vs. 333 ± 372 min; p = 0.665), but TA+ group had higher maximum values of troponin I (39.5 ± 30.5 vs. 27.6 ± 26.9 ng/ml; p < 0.001). The echocardiography revealed similar left ventricular volumes and systolic function, but TA+ group had significantly higher incidence of E/e' > 15, as a marker of severe diastolic dysfunction' (TA+ 23.1% vs. TA- 15.2%; p = 0.050). During average follow-up of 14 ± 5 months, major adverse cardiac/cerebral events occurred at the similar rate (log rank p = 0.867). CONCLUSION: Thrombus aspiration is associated with a greater incidence of severe diastolic dysfunction in unselected STEMI patients treated with primary PCI, but it doesn't influence the incidence of major adverse cardiovascular events.

AIM: As a result of a higher prevalence of comorbidities, elderly adults are often underrepresented in clinical trials, and more often experience complications during percutaneous coronary intervention. Our aim was to evaluate clinical outcomes of patients older than 80 years, compared with their younger counterparts, when bioresorbable polymer biolimus A9 drug-eluting stent is used for their treatment. METHODS: The prospective, observational e-Nobori registry was created to validate the safety and efficacy of bioresorbable polymer drug-eluting stent in unselected patients. The primary end-point of the study was freedom from target lesion failure defined as a composite of cardiac death, target vessel-related myocardial infarction and clinically-driven target lesion revascularization at 1 year. RESULTS: There were 781 (7.8%) octogenarians, they were less frequently male (62% vs 77%; P < 0.0001) and more often presented as acute coronary syndrome (44% vs 39%; P = 0.0182). The index percutaneous coronary intervention success was lower in the elderly patients (98% vs 99%; P = 0.0398). One-year follow up was completed for 97% of the elderly patients and 99% of the younger patients. The difference in target lesion failure (3.33% vs 2.83%; log-rank P = 0.0114) was mainly driven by increased mortality in octogenarians (3.73% vs 1.47%; P < 0.0001). Elderly patients had more bleeding and vascular complications (2.67% vs 1.05%; P = 0.0001). CONCLUSIONS: Despite advanced age, multiple comorbidities and complexity of treated lesions, clinical outcomes are favorable in octogenarians treated by bioresorbable polymer biolimus A9 drug-eluting stent.

Diagnosing heart failure with preserved ejection fraction (HFpEF) in patients with chronic obstructive pulmonary disease (COPD) is difficult due to overlapping pathophysiological pathways, risk factors and clinical presentations. We investigated the prevalence and prognostic implications of coexisting HFpEF in patients hospitalized for acute exacerbation of COPD. A total of 116 consecutive patients with an acute exacerbation of COPD were evaluated for HFpEF and followed for an average period of 22 ± 9 months for the occurrence of death from any cause. HFpEF was diagnosed in 22 (19 %) patients with COPD, who were older, and also had higher LV mass, left atrial size, and mitral E/Ea ratio than those without HFpEF (p < 0.05 for all comparisons). HFpEF was not independently associated with all-cause mortality [hazard ratio (HR) 1.07, 95 % confidence interval (CI) 0.44-2.62]. Global initiative for chronic Obstructive Lung Disease (GOLD) stage (IV vs. I-III, HR 2.37, CI 1.23-4.59) and N-terminal pro B-type natriuretic peptide (NT-proBNP) levels (HR 2.79, CI 1.12-6.98) were independent predictors of long-term survival. HFpEF is present in one-fifth of patients with exacerbated COPD. Non-invasively diagnosed HFpEF may not be an independent predictor of all-cause mortality. Elevated NT-proBNP levels and very severe COPD were independently associated with unfavorable overall survival.

INTRODUCTION: Echocardiography is a highly operator-dependant technique which requires adequate training and skills that are frequently not present, considering the widespread use of cardiovascular ultrasound. This could particularly be true for hand-held echo devices which made echocardiography more accessible but are frequently used by non-cardiologists and non-experts. OUTLINE OF CASES: We present a 45-year-old female and a 37-year-old male with heart murmurs due to atrial and ventricular septal defect, respectively. Congenital septal defects were undiagnosed in both patients during several outpatient examinations due to challenging image acquisition. C reful re-evaluation revealed that, depending on the scanning technique, it was possible to detect or overlook the real cause of the murmur using either hand-held or high-end echo device. CONCLUSION: Our report underlines the need of adequate knowledge and training of medical professionals performing pocket-size hand-held echocardiography, since potential misdiagnoses may not be related to limited imaging capabilities of pocket-sized echo devices only, but also to inability of insufficiently trained users to obtain good quality images and interpret them adequately.

AIMS: Ischaemic but viable myocardium may exhibit prolongation of contraction and QT interval duration, but it is largely unknown whether non-invasive assessment of regional heterogeneities of myocardial deformation and QT interval duration could identify patients with significant coronary artery disease (CAD). METHODS AND RESULTS: We retrospectively studied 205 patients with suspected CAD who underwent coronary angiography. QTc dispersion was assessed from a 12-lead electrocardiogram (ECG) as the difference between the longest and shortest QTc intervals. Contraction duration was assessed as time from the ECG R-(Q-)wave to peak longitudinal strain in each of 18 left ventricular segments. Mechanical dispersion was defined as either the standard deviation of 18 time intervals (dispersionSD18) or as the difference between the longest and shortest time intervals (dispersiondelta). Longitudinal strain was measured by speckle tracking echocardiography. Mean contraction duration was longer in patients with significant CAD compared with control subjects (428 ± 51 vs. 410 ± 40 ms; P = 0.032), and it was correlated to QTc interval duration (r = 0.47; P < 0.001). In contrast to QTc interval duration and dispersion, both parameters of mechanical dispersion were independently associated with CAD (P < 0.001) and had incremental value over traditional risk factors, wall motion abnormalities, and global longitudinal strain (GLS) for the detection of significant CAD. CONCLUSION: The QTc interval and myocardial contraction duration are related to the presence of significant CAD in patients without a history of previous myocardial infarction. Myocardial mechanical dispersion has an incremental value to GLS for identifying patients with significant CAD.

AIMS: We sought to determine the prevalence of overt and subclinical LV dysfunction in patients with critical left anterior descending coronary artery (LAD) stenosis but without a history of myocardial infarction and to compare diagnostic value of routine echocardiographic parameters with myocardial strain analysis for detection of critical LAD stenosis. METHODS AND RESULTS: We retrospectively studied 269 patients with suspected coronary artery disease (CAD)-209 consecutive patients with critical LAD stenosis and 60 consecutive patients with atypical chest pain and without CAD. Conventional visual assessment of LV asynergy in the LAD territory was compared with global, regional, and segmental peak systolic longitudinal strain (PSLS) parameters derived by two-dimensional speckle tracking echocardiography (2D STE). Wall motion abnormalities in the LAD territory were found in 41% of patients with critical LAD stenosis, whereas, depending on the cut-off value, global longitudinal strain (GLS) was impaired in 42-69% of patients. GLS with an area under the receiver operating characteristic curve (AUC) of 0.85 showed better discriminative power for detecting critical LAD stenosis than conventional wall motion score index (AUC 0.73, P < 0.05, for the difference between the AUCs). PSLS values were significantly lower in basal and midventricular segments supplied by critically narrowed LAD, particularly if they also appeared dysfunctional on visual assessment. CONCLUSIONS: Detection of subclinical LV dysfunction by 2D STE might improve identification of patients with critical LAD stenosis, although visually apparent regional LV dysfunction in the LAD territory is not uncommon finding in this subset of patients.

This prospective, first-in-man, open-label multicenter study sought to assess the pharmacokinetics of sirolimus after Ultimaster drug-eluting stent implantation (coated with sirolimus and bioabsorbable co-polymer) in patients with de novo coronary artery disease (the TCD-10023 PK study). The primary endpoint was sirolimus concentration in peripheral whole blood at 28 days after stent implantation. In addition, safety, tolerability, therapeutic outcome and vasomotor response after stent implantation were studied. Twenty patients were enrolled in the study. Blood samples for the measurements of sirolimus concentration were collected at eight time points during first 48 h, at 7 days and 28 days after stent implantation. Patients underwent 6-month angiographic and up to 12 months clinical follow-up. At 28 days, only two of 20 patients had sirolimus concentrations above lower limit of quantification (20.0 pg/mL). The highest sirolimus blood concentration was 105 pg/mL. The median maximum concentration was 36.8 pg/mL (range 22.9-41.5 pg/mL) for stent 3.0 × 15 mm and 87.2 pg/mL (range 60.0-105.0 pg/mL) for 3 × 28 mm stent. The median systemic exposure, as measured by the area under the time-concentration curve, was 8.3 ng h/mL (range 6.47-28.0 ng h/mL). At 6 months, endothelial function was well preserved, and up to 12 months, there were no signs of sirolimus toxicity nor any other safety concerns. Our results demonstrate that implantation of Ultimaster stent resulted in almost nondetectable sirolimus in blood after 28 days. These findings were translated into exceptional safety profile, without any sign of systemic toxicity.

OBJECTIVES: To evaluate the safety and effectiveness of the Kaname™ cobalt-chromium (Co-Cr), thin strut, bare metal stent (BMS) system for the treatment of coronary artery lesions. BACKGROUND: Despite widespread use of drug-eluting stents, a certain percentage of patients with coronary artery disease are still treated with BMS. Therefore, it is essential to evaluate their clinical performance. METHODS: Two hundred eighty-two patients were enrolled in this prospective, single-arm study including a predefined subset of 79 patients with small vessels. The primary end-point was freedom from target vessel failure (TVF) at 6 months. Key angiographic and intravascular ultrasound (IVUS) end-points were late loss, diameter stenosis, binary restenosis, and neointimal hyperplasia volume. RESULTS: Freedom from TVF at 6 months was 93.3% and at 1 year 90.8% in total population, and 92.4% and 87.3% in small vessels, respectively. Clinically driven target lesion revascularization (TLR) rates at 6 and 12 months were 4.3% and 6.4% in total population, and 3.8% and 7.6% in small vessels, respectively. At 6 months in-stent late loss was 0.75 ± 0.43 mm and binary restenosis rate was 16.9% in total population, and 0.64 ± 0.40 mm and 26.1% in small vessels, while IVUS assessed neointimal hyperplasia volume at 6 months was 128.9 ± 42.6 mm(3) for total population. There were no definite and probable stent thromboses up to 12 months. CONCLUSIONS: Results indicate good safety and effectiveness of the Kaname™ stent with clinically equivalent results in small and larger vessels, as such providing useful treatment option for patients with ischemic heart disease considered for BMS implantation.

BACKGROUND/AIM: Long-term intensive training is associated with distinctive cardiac adaptations which are known as athlete's heart. The aim of this study was to determine whether the use of anabolic androgenic steroids (AAS) could affect echocardiographic parameters of left ventricular (LV) morphology and function in elite strength and endurance athletes. METHODS: A total of 20 elite strength athletes (10 AAS users and 10 non-users) were compared to 12 steroid-free endurance athletes. All the subjects underwent comprehensive standard echocardiography and tissue Doppler imaging. RESULTS: After being indexed for body surface area, both left atrium (LA) and LV end-diastolic diameter (LVEDD) were significantly higher in the endurance than strength athletes, regardless of AAS use (p < 0.05, for both). A significant correlation was found between LA diameter and LVEDD in the steroid-free endurance athletes, showing that 75% of LA size variability depends on variability of LVEDD (p < 0.001). No significant differences in ejection fraction and cardiac output were observed among the groups, although mildly reduced LV ejection fraction was seen only in the AAS users. The AAS-using strength athletes had higher A-peak velocity when compared to steroid-free athletes, regardless of training type (p < 0.05 for both). Both AAS-using and AAS-free strength athletes had lower e' peak velocity and higher E/e' ratio than endurance athletes (p < 0.05, for all). CONCLUSIONS: There is no evidence that LV ejection fraction in elite athletes is altered by either type of training or AAS misuse. Long-term endurance training is associated with preferable effects on LV diastolic function compared to strength training, particularly when the latter is combined with AAS abuse.

INTRODUCTION: Spontaneous coronary artery dissection (SCAD) is a rare cause of the acute coronary syndrome. It occurs mostly in patients without atherosclerotic coronary artery disease, carrying fairly high early mortality rate. The treatment of choice (interventional, surgical, or medical) for this serious condition is not well-defined. CASE REPORT: A 41-year old woman was admitted to our hospital after the initial, unsuccessful thrombolytic treatment for anterior myocardial infarction administered in a local hospital without cardiac catheterization laboratory. Immediate coronary angiography showed spontaneous coronary dissection of the left main and left anterior descending coronary artery. Follow-up coronary angiography performed 5 days after, showed extension of the dissection into the circumflex artery. Because of preserved coronary blood flow (thrombolysis in myocardial infarction - TIMI II-III), and the absence of angina and heart failure symptoms, the patient was treated medicaly with dual antiplatelet therapy, a low molecular weight heparin, a beta-blocker, an angiotensin-converting enzyme (ACE) inhibitor and a statin. The patient was discharged after 12 days. On follow-up visits after 6 months and 2 years, the patient was asymptomatic, and coronary angiography showed the persistence of dissection with preserved coronary blood flow. CONCLUSION: Immediate coronary angiography is necessary to assess the coronary anatomy and extent of SCAD. In patients free of angina or heart failure symptoms, with preserved coronary artery blood flow, medical therapy is a viable option. Further evidence is needed to clarify optimal treatment strategy for this rare cause of acute coronary syndrome.

BACKGROUND: With a potential of detecting subtle myocardial injury, two-dimensional (2D) speckle tracking-derived strain could help to distinguish between ischemic and nonischemic ST-segment elevation. Little is known if limitations of strain imaging could prevent its applicability in acute cardiac care settings. CASE PRESENTATION: We present a 56-year-old male with persistent ST-segment elevation in the inferolateral leads and suspected hypokinesia of the inferior wall. Semiautomated 2D speckle tracking strain analysis showed normal longitudinal peak systolic strain (LPSS) in all segments of the inferior wall, ruling out wall-motion abnormalities in this region. Stationary reverberations and spuriously low values of LPSS in the posterolateral wall required operator's expertise to distinguish pathological myocardial deformation from artifacts. Additional workup revealed that early repolarization pattern was mistaken for the inferior wall acute myocardial infarction in our patient. CONCLUSIONS: Semiautomated quantification of regional left ventricular function by 2D speckle tracking echocardiography could facilitate decision making even in the emergency settings. Due to intrinsic limitations of this novel method, its actual clinical value in acute cardiac care settings may depend on the expertise of the operator and is yet to be determined.

BACKGROUND: The aim of our study was to examine regional differences in the demographics, etiology, risk factors, comorbidities and treatment of female patients with heart failure (HF) in the Cardiac Insufficiency BIsoprolol Study in ELDerly (CIBIS-ELD) clinical trial. METHODS AND RESULTS: One hundred and fifty-nine female patients from Germany and 169 from Southeastern (SE) Europe (Serbia, Slovenia and Montenegro) were included in this subanalysis of the CIBIS-ELD trial. Women comprised 54% of the study population in Germany and 29% in SE Europe. German patients were significantly older. The leading cause of HF was arterial hypertension in German patients, 71.7% of whom had a preserved ejection fraction. The leading etiology in SE Europe was the coronary artery disease; 67.6% of these patients had a reduced left ventricular ejection fraction (34.64 ± 7.75%). No significant differences were found in the prevalence of traditional cardiovascular risk factors between the two regions (hypertension, diabetes, hypercholesterolemia, smoking and family history of myocardial infarction). Depression, chronic obstructive pulmonary disease and malignancies were the comorbidities that were noted more frequently in the German patients, while the patients from SE Europe had a lower glomerular filtration rate. Compared with the German HF patients, the females in SE Europe received significantly more angiotensin converting enzyme inhibitors, loop diuretics and less frequently angiotensin receptor blockers and mineralocorticoid receptor antagonists. CONCLUSIONS: Significant regional differences were noted in the etiology, comorbidities and treatment of female patients with HF despite similar risk factors. Such differences should be considered in the design and implementation of future clinical trials, especially as women remain underrepresented in large trial populations.

INTRODUCTION: Rapidly vanishing lung pseudotumor (phantom tumor) refers to the transient well-demarcated accumulation of pleural fluid in the interlobar pulmonary fissures. Most frequently their appearance is associated with congestive heart failure, but also other disorders like hypoalbuminemia, renal insufficiency or pleuritis. Its rapid disappearance in response to the treatment of the underlying disorder is a classical feature of this clinical entity. CASE REPORT: A 47-year-old woman, chronic smoker with symptoms of shortness of breath, orthopnea, chills, cough, weakness and the temperature of 39.2 degrees C was admitted to our hospital. A posteroanterior chest X-ray revealed cardiomegaly with the cardiothoracic ratio of > 0.5, blunting of both costophrenic angles and an adjacent 6 x 5 cm well-defined, rounded opacity in the right interlobar fissure. Transthoracic 2-dimensional echocardiography demonstrated left ventricular hyperthrophy with a systolic ejection fraction of 25% and moderate mitral regurgitation. The patient's symptoms resolved rapidly after diuresis, and repeated chest X-ray four days later showed that the right lung opacity and pleural effusions had vanished. CONCLUSION: The presented case underlines the importance of the possibility of vanishing lung tumor in patients with left ventricular failure and a sharp oval lung mass on the chest X-ray. This is the way to avoid incorrect interpretation of this finding causing additional, unnecessary, costly or invasive imaging, interventions and drugs.

CONFLICT OF INTEREST: NONE DECLARED. INTRODUCTION: P-wave abnormalities on the resting electrocardiogram have been associated with cardiovascular or pulmonary disease. So far, "Gothic" P wave and verticalization of the frontal plane axis is related to lung disease, particularly obstructive lung disease. AIM: We tested if inverted P wave in AVl as a lone criteria of P wave axis >70° could be screening tool for emphysema. MATERIAL AND METHOD: 1095 routine electrocardiograms (ECGs) were reviewed which yielded 478 (82,1%) ECGs with vertical P-axis in sinus rhythm. Charts were reviewed for the diagnosis of COPD and emphysema based on medical history and pulmonary function tests. CONCLUSION: Electrocardiogram is very effective screening tool not only in cardiovascular field but in chronic obstructive pulmonary disease. The verticality of the P axis is usually immediately apparent, making electrocardiogram rapid screening test for emphysema.
