Abstract

Abstract Background Endothelial progenitor cells (EPC) which are characterised by the simulateous expression of CD34, CD133 and vascular endothelial growth receptor 2 (VEGF 2) are involved in the pathophysiology of congestive heart failure (CHF) and their number and function is reduced in CHF. But so far our knowledge about the number of circulating hematopoietic stem/progenitor cells (CPC) expressing the early hematopoietic marker CD133 and CD34 in CHF is spares and therefore we determined their number and correlated them with New York Heart Association (NYHA) functional class. Methods CD34 and CD133 surface expression was quantified by flow cytometry in the peripheral venous blood of 41 healthy adults and 101 patients with various degrees of CHF. Results CD34+, CD133+ and CD34+/CD133+ cells correlated inversely with age. Both the number of CD34+ and of CD34+/CD133+ cells inversely correlated with NYHA functional class. The number of CD133+ cells was not affected by NYHA class. Furthermore the number of CD133+ cells did not differ between control and CHF patients. Conclusion In CHF the release of CD34+, CD133+ and CD34+/CD133+ cells from the bone marrow seems to be regulated differently. Modulating the releasing process in CHF may be a tool in CHF treatment.

Abstract

High doses of verapamil, diltiazem or nifedipin were administered to three groups of eight patients each, with severely abnormal left-ventricular (LV) function (mean ejection fraction 0.29). Various haemodynamic measurements were made immediately before and 30 minutes after drug administration: LV ejection fraction, ratio of peak systolic pressure to endsystolic volume index, stroke index, pulmonary capillary closing pressure, and maximal diastolic filling rate. None of these were reduced. In fact, ejection fraction rose by a mean of 0.05, stroke index by a mean of 5 ml/m2, while p.c. closing pressure and contractility did not alter significantly. Verapamil and diltiazem reduced the pressure X rate product (an important determinant of oxygen consumption); nifedipine reduced total systemic resistance. It is concluded that verapamil and diltiazem can be used with advantage in cases of unstable angina, if there are severe abnormalities of LV function; they are to be preferred to beta-blockers in this situation. Nifedipin is the calcium antagonist of choice in hypertension and abnormal LV function.

Abstract

History and clinical findings A 41-year-old woman, known for 10 month to have polycythaemia vera, developed severe right upper abdominal pain. The abdomen was tense from marked ascites and the liver enlarged by 18 cm in the mid-clavicular line. Investigations Serum bilirubin was slightly elevated to 2.2mg/dl, liver synthesis being much reduced (recalcifying time minimally 23%, albumin minimally 2.8 g/dl). Doppler sonography detected no flow in the right and middle hepatic veins, indicating Budd-Chiari syndrome. Portal vein flow was diminished. Treatment and course Heparin treatment had to be stopped because of heparin-associated type II thrombocytopenia and hirudin was substituted. Attempted lysis with a total of 100 mg r-tPA failed. As the patient's condition deteriorated a TIPSS was implanted to provide portal decompression. Incomplete portal vein thrombosis was demonstrated and worsened during the procedure until nearly complete occlusion. Local lysis treatment for 2 days with urokinase, 50,000-60,000 U/h, and two shunt revisions finally succeeded in completely dissolving the thrombus. Portocaval pressure fell from 32 to 21 mm Hg, and the size and function of the liver became almost normal and the ascites disappeared. Anticoagulation with a coumarin derivative was started and hydrocarbamide again given for recurrent thrombocytosis. The patient remained largely symptom-free one year after TIPSS. Conclusion This case demonstrates the effectiveness of TIPSS in Budd-Chiari syndrome, even in complicated portal vein thrombosis.

Abstract

HISTORY AND CLINICAL FINDINGS A 68-year-old woman, with a cardiac murmur known since childhood and suffering from increasing dyspnoea for several years, was admitted to hospital after echocardiography had suggested pulmonary valve stenosis and an atrial septal defect. While her general condition was satisfactory, she had marked central cyanosis with clubbed fingers and moderate bilateral oedema of the lower legs. A rough, diamond-shaped systolic murmur was heard, loudest over the left 2nd intercostal space. In addition to a cardiac defect with right to left shunt, primary pulmonary disease with cor pulmonale was considered in the differential diagnosis. EXAMINATIONS Haemoglobin content was 25.1 g/dl, haematocrit 72.4%, red cell count 7.44 x 10(6). Arterial oxygen partial pressure was 40 mm Hg, arterial oxygen saturation 81.8%, Echocardiography further revealed right ventricular enlargement, marked tricuspid regurgitation and a stenosed calcified pulmonary valve. At right heart catheterization a right to left interatrial shunt was calculated at 47% of systemic flow and a systolic pressure gradient between right ventricle and pulmonary artery of 131 mm Hg was measured. TREATMENT AND COURSE Haemoglobin content was lowered to 19.4 g/dl after bloodletting. Balloon pulmonary valvuloplasty reduced the transvalvular systolic gradient to 31 mm Hg. The further course was without complication: 4 months later the patient had only grade II (NYHA) dyspnoea, the oxygen saturation was 91.3%. CONCLUSION Severe pulmonary valve stenosis with right to left interatrial shunt can be successfully treated by balloon dilatation even in elderly patients.

Abstract

HISTORY AND CLINICAL FINDINGS: A 55-year-old woman with known primary biliary cirrhosis (PBC) was hospitalized because of increasing dyspnoea. A year before she had for the first time experienced a right-sided pleural effusion which had to be drained every 4 weeks. Physical examination revealed dullness on percussion and greatly decreased breath sounds on auscultation over the entire right thorax. In addition there were signs of moderate ascites and leg oedema. INVESTIGATIONS: Chest radiograph showed a homogeneous shadowing of the right thorax without mediastinal shift. Diagnostic thoracocentesis produced a serous effusion, a transudate on chemical analysis, comparable to the composition of the ascitic fluid. Bacteriological and cytological tests on both fluids were unremarkable. TREATMENT AND COURSE: The right pleural effusion was presumed to be due to a hydrothorax from the ascites caused by portal hypertension associated with the PBC. Despite continuous diuretic treatment and thoracocentesis with albumin substitution every 3 days there was no improvement and implantation of a transjugular intrahepatic portosystemic stent shunt (TIPSS) was performed. This effectively lowered portal pressure and markedly improved the patient's condition so that further thoracocentesis were no longer necessary. 3 weeks after TIPSS implantation she was discharged in good condition. Radiography 3 weeks later demonstrated continued reduction in the hydrothorax. CONCLUSION: Hydrothorax is a rare complication of liver cirrhosis. TIPSS implantation can provide lasting resolution and corresponding clinical improvement of a hydrothorax, especially in those conditions which are refractory to diuretic treatment and thoracocentesis.

27. Smelling heart failure from human skin odor with an electronic nose.

Author

Abstract

The human body odor contains different volatile organic compounds which can be used as biomarkers for various diseases. The early detection of heart failure (HF) through periodical screening provides an early treatment application. Therefore we have developed a completely new non-invasive method to identify HF applying an “electronic nose” (e-nose) which provides a “smelling” of the disease based on the analysis of sweat volatile gases from the skin surface. For this e-nose a special applicator carrying the sensor chip was developed which can be applied directly on the skin surface. 27 patients with decompensated HF (DHF), 25 patients with compensated HF (CHF, mean age 70.72 ± 12.02) and 28 controls (CON) were enrolled in this first pilot study.

30. Lagged segmented Poincaré plot analysis for risk stratification in patients with dilated cardiomyopathy.

Abstract

The objectives of this study were to introduce a new type of heart-rate variability analysis improving risk stratification in patients with idiopathic dilated cardiomyopathy (DCM) and to provide additional information about impaired heart beat generation in these patients. Beat-to-beat intervals (BBI) of 30-min ECGs recorded from 91 DCM patients and 21 healthy subjects were analyzed applying the lagged segmented Poincaré plot analysis (LSPPA) method. LSPPA includes the Poincaré plot reconstruction with lags of 1-100, rotating the cloud of points, its normalized segmentation adapted to their standard deviations, and finally, a frequency-dependent clustering. The lags were combined into eight different clusters representing specific frequency bands within 0.012-1.153 Hz. Statistical differences between low- and high-risk DCM could be found within the clusters II-VIII (e.g., cluster IV: 0.033-0.038 Hz; p = 0.0002; sensitivity = 85.7 %; specificity = 71.4 %). The multivariate statistics led to a sensitivity of 92.9 %, specificity of 85.7 % and an area under the curve of 92.1 % discriminating these patient groups. We introduced the LSPPA method to investigate time correlations in BBI time series. We found that LSPPA contributes considerably to risk stratification in DCM and yields the highest discriminant power in the low and very low-frequency bands. [ABSTRACT FROM AUTHOR]

36. Segmented Poincaré plot analysis for risk stratification in patients with dilated cardiomyopathy.

Abstract

Background: The prognostic value of heart rate variability in patients with dilated cardiomyopathy (DCM) is limited and does not contribute to risk stratification although the dynamics of ventricular repolarization differs considerably between DCM patients and healthy subjects. Neither linear nor nonlinear methods of heart rate variability analysis could discriminate between patients at high and low risk for sudden cardiac death.Objective: The aim of this study was to analyze the suitability of the new developed segmented Poincaré plot analysis (SPPA) to enhance risk stratification in DCM.Methods: In contrast to the usual applied Poincaré plot analysis the SPPA retains nonlinear features from investigated beat-to-beat interval time series. Main features of SPPA are the rotation of cloud of points and their succeeded variability depended segmentation.Results: Significant row and column probabilities were calculated from the segments and led to discrimination (up to p<0.005) between low and high risk in DCM patients.Conclusion: For the first time an index from Poincaré plot analysis of heart rate variability was able to contribute to risk stratification in patients suffering from DCM.

Abstract

The hemodynamic courses of 56 patients with congestive cardiomyopathy (CCM) were investigated. Fourteen patients died within 24 months after diagnosis. The hemodynamic courses of the remaining 42 patients were investigated in subsequent examinations by determination of left ventricular ejection fraction (LVEF), mean pulmonary arterial pressure at maximal workload, and peak systolic pressure/end-systolic volume index. During the study interval of 32.2 +/- 20.0 months the conditions of 20 patients (48%) deteriorated, according to their hemodynamic status, and at least five of these died of terminal heart failure. Surprisingly, the conditions of 22 patients (52%) improved or stabilized. One of these died of leukemia. Seven patients in the latter group with initial LVEFs of 0.30 or less experienced an average increase from 0.22 to 0.51. Retrospectively consideration of age, alcohol intake, exercise capacity, and hemodynamic status were not helpful in predicting the course of the disease. In 38 patients endomyocardial biopsy samples could be obtained at the time of diagnosis. Reduced myofibril volume fraction (less than 60%) had prognostic significance for both hemodynamic deterioration and death (sensitivity 23/24 = 96%), while 14 of 15 patients whose conditions improved or stabilized had a myofibril volume fraction of 60% or more (specificity 14/15 or 93%, p less than .002). A relationship between hemodynamic status and the myofibril volume fraction could not be found. Individual patients with CCM differ significantly with respect to course of the disease. A distinct separation of the patients by means of morphologic criteria is possible. This makes it more likely that the pathogenesis of the disease is not unique.

Abstract

Treatment with percutaneous extracorporeal mechanical assist devices provides the ultimate therapeutic option to improve the macrocirculation in patients suffering from refractory cardiac arrest, severe cardiogenic shock or during high-risk interventions. However, the flow in the smallest vessels in these critical periods is poorly understood but prognostically of high importance. Using sidestream darkfield intravitalmicroscopy, we visualised the sublingual microflow in a patient suffering from severe cardiogenic shock supported by extracorporeal membrane oxygenation and intra-aortic balloon pump. Our results show that intra-aortic balloon counterpulsation applied in addition to extracorporeal membrane oxygenation further improves the microflow. This in vivo finding supports pilot studies favouring the application of devices supporting cardiac output (extracorporeal membrane oxygenation) together with devices aimed at pulsatility (intra-aortic balloon pump).

Abstract

Light reflected from the human heart surface was used to determine mixed hemoglobin and myoglobin oxygen saturations (O2SAT) in the cardiac tissue. The measurements were performed in 8 patients with coronary heart disease including stenosis of left anterior descending coronary artery (LAD) who underwent aorto-coronary bypass surgery. At the end of the operation the O2SAT was measured in the supply area of the LAD either with patent or occluded coronary bypass. In 13 experiments occlusion of the bypass resulted in a decrease of O2SAT from 74 +/- 16% to 61 +/- 24% (p less than 0.02). A new technique is introduced and its limitations are discussed. Preliminary results of application in coronary bypass surgery demonstrate an increase in tissue oxygenation following myocardial revascularization.

Abstract

OBJECTIVE: Magnetic field imaging (MFI) combines depolarization and repolarization registration of the cardiac electromagnetic field with a 3D current distribution model. An interesting application for MFI is the possibility to detect myocardial ischemia under stress. METHODS: Using a new reconstruction technique, it is possible to generate a pseudo-current distribution on the epicardial surface: the comparison of the time evolution of such current distributions at rest and under stress shows difference in coronary artery disease (CAD). The model works with a realistic epicardial surface generate on the basis of computerised tomography or magnetic resonance tomography data or with a standardized ellipsoidal model. To take into account the vectorial character of the epicardial current distribution, the current flow in the epicardial surface element is represented in the graphic display by a cone. Thus indicating the direction of current flow the height of the cone represents the current intensity. RESULTS: As an example of the method, data of pharmacological stress MFI on a CAD patient will be presented. The newly developed algorithm operates in different segments of the electromagnetic heart beat. The indicated myocardial area strongly correlated to invasive coronary angiography results. In such a situation the advantage provided by the 'friendly' ellipsoidal surface on the numerical solution of the inverse problem seems to overcome the advantage of a realistic heart model. CONCLUSION: We conclude MFI is a promising procedure for a non-invasive stress testing as well as screening method as for localization of myocardial ischemia. [ABSTRACT FROM AUTHOR]

Abstract

Background: Handheld ultrasound devices allow for a bedside screening although quantitative parameters are not easily obtained. We aim to assess the reliability of visual qualitative evaluation of left ventricle (LV) compared with standard quantitative evaluation with 2D transthoracic echocardiography (TTE). Methods: Two cardiologists have reviewed 135 consecutive standard TTE examinations. Both observers visually assessed LV size, hypertrophy (LVH) and ejection fraction (EF). LV diameter, volume, wall thickness and EF (Teichholz and Simpson) were also measured by both observers. Visual and quantitative agreement and inter and intraobserver variability were calculated. Results: Image quality allowed for evaluation of 130 examinations. Visually assessed EF compared with Simpson had better consistency (Intraclass correlation coefficient [ICC] 0,91 IC95% 0,88-0,94) than with Teichholz (ICC 0,75 IC95% 0,66-0,82). We have also observed good interobserver agreement regarding visually assessed EF (ICC 0,81 IC95% 0,71-0,87) and Simpson EF (ICC 0,80 IC95% 0,70-0,89) as well as good intraobserver agreement (visual EF: ICC 0,81 IC95% 0,74-0,86; Simpson: ICC 0,89 IC95% 0,84-0,93). Regarding LVH we found moderate agreement between visual and quantitative assessment (weighted Kappa [wK] 0,44 (IC95% 0,32-0,56)), moderate interobserver agreement for quantitative assessment (ICC 0,59 IC95% 0,44-0,71) and poor interobserver agreement for visual assessment (wK 0,19 IC95% 0,08-0,30). Intraobserver variability regarding LVH visual estimation was moderate (wK 0,40 IC95% 0,29-0,52) and regarding LVH quantification was good (ICC 0,78 IC95% 0,70-0,84). LVH was visually overestimated in 25% of examinations. Regarding LV size, we found poor agreement between visual assessment and its quantification with end-diastolic diameter (wK 0,22 IC95% 0,06-0,39) and moderate agreement between visual assessment and end-systolic LV volume (wK 0,62 IC95% 0,47-0,77). Interobserver agreement regarding quantitative volume assessment was good (ICC 0,90 IC95% 0,85-0,94) and regarding visual assessment was moderate (wK 0,43 IC95% 0,26-0,70). We found good intraobserver variability of volume measurement (wK 0,64 IC95% 0,50-0,78) and of visual size assessment (ICC 0,96 IC95% 0,94-0,97). Conclusions: Visual LVEF assessment is consistent with quantitative assessment and should be regarded as a reliable parameter that can be obtained from bedside examination with a handheld device. Visual assessment of LV size and wall thickness is less reliable than its quantification and should be confirmed with standard measurements.

Abstract

Purpose: Left atrial function (LAF) has emerged as a novel determinant of clinical status and outcomes in heart failure (HF). Significant functional mitral regurgitation (SFMR) is an important and prevalent pathophysiological and prognostic factor in this patient population, yet its effects on LAF are poorly understood. Aim of this study was to explore the possible interplay between the severity of functional MR and reduced LAF in patients with systolic HF. Methods: Echocardiography was performed in 93 patients (age 61 ± 15 yrs) with HF (NYHA functional class II-IV) due to left ventricular systolic dysfunction (LVEF ≤ 40%), sinus rhythm, and mild to severe functional mitral regurgitation; subjects with any evidence of organic mitral valve disease were excluded. MR severity was estimated using a multiparametric approach, and patients were dichotomized based on the presence of SFMR (3-4+). LV and LA volumes were evaluated using Simpson’s biplane method. LA volumes were measured at three time-points: just before mitral valve opening, at P-wave onset, and at mitral valve closure. According to previously described formulas, the different components of LA function were calculated: total LA emptying function (TLAEF), LA reservoir function (LAEI), LA passive emptying fraction (conduit function, LAPEF), and LA active emptying fraction (contractile function, LAAEF). Results: The two groups (SFMR -/+) were well matched in terms of demographics, HF etiology, and LV systolic function (29.3 ± 9.7 vs 28.1 ± 7.2 %). Patients with SFMR displayed worse clinical status (NYHA 2.19 ± 1.00 vs 2.72 ± 0.98; p<0.02), larger LV (LVEDVi 100 ± 32 vs 128 ± 38 ml/sqm; p=0.001) and LA volumes (maximal LAVi 38 ± 20 vs 57 ± 27 ml/sqm; p=0.001) compared to those without SFMR. LA reservoir (63 ± 40 vs 35 ± 26 %; p=0.006) and contractile function (21 ± 14 vs 12 ± 11 %; p<0.02) were significantly more impaired in patients with SFMR, while no difference was found in terms of LA conduit function (18 ± 13 vs 17 ± 18 %; p=ns). LAF was inversely correlated with NYHA functional class. Conclusions: The presence of SFMR seems to significantly affect left atrial reservoir and contractile function in patients with LV systolic dysfunction, independently of LVEF. Further research will elucidate the prognostic and therapeutic interactions between LA dysfunction and SFMR in the HF population.

Abstract

Clinical PET acquisitions of the heart suffer from artefacts and drops in image quality due to the poor spatial resolution of the PET system. Moreover, cardiac PET images are further degraded by the blur caused by the breathing and beating motions, thus hampering diagnosis and evaluation of myocardial pathologies. Anatomy-enhanced PET reconstruction, using a high-resolution CT, has proven useful in brain imaging. In cardiac datasets however, due to the motion artefacts, the application of any restoring technique on datasets affected by motion blur needs to be preceded by the validation of the proposed method on realistic static datasets. In this work, the validation is performed using static cardiac ex vivo datasets obtained from a number of sacrificed sheep, scanned on a clinical PET/CT scanner. The aim of this work is to assess the effectiveness of reconstructions of the acquired datasets with different CT-based anatomical priors, in comparison to reconstructions currently applied in clinical practise. The gold standard to which all reconstructions are compared consists of images of the same hearts scanned on a small-animal PET scanner, whose high spatial resolution allows for almost artefact-free images. Encouraging results were obtained so far, with improvements in volume delineation and uniformity of activity values when anatomical information was used. Fig 1 shows the gold standard image (left) compared to a regular clinical reconstruction (middle) and to a reconstruction using the high-resolution CT as anatomical information (right). Figure

Abstract

Purpose: Patients with rheumatic mitral stenosis (MS) are at increased risk of thromboembolic consequences. Owing to the higher risk of these complications, anticoagulant therapy is mandatory in MS associated with atrial fibrillation (AF). However, time to begin prophylactic anticoagulant therapy in normal sinus rhythm (NSR) is not yet clear. Left atrial (LA) enlargement has been proposed as potential surrogate for thrombus formation and subsequent embolization. We examined various LA echocardiographic parameters to detect possible predictors of embolization in MS and NSR. Methods: Our study included 79 patients with rheumatic MS in NSR. Case group (n=36) included patients with history of prior embolic events; while control group (n=43) included patients without history of embolization. All the studied population underwent history taking, clinical examination and ECG to rule out AF and confirm manifestations of embolization in the case group. Patients with CVS underwent bilateral carotid duplex to rule out Carotid artery stenosis. Other causes of embolization were excluded. Routine transthoracic echocardiogram (TTE) was done and LA volumes (LAV) were measured using both area-length (A-L) and prolate-ellipsoid methods. LAV maximum (end systolic; Vmax), LAV minimum (end diastolic;Vmin) and LAV at onset of atrial systole (end of P wave on surface ECG;Vp) were measured by the two methods. The LA phasic indices were calculated given the aforementioned LAVs as follows: Passive emptying volume (PEV)= Vmax-Vp, Passive emptying fraction (PEF) = PEV/Vmax, Active emptying volume (AEV)= Vp-Vmin, Active emptying fraction (AEF) = AEV/Vp and Total emptying volumes (TEV) = PEV + AEV. Comparison between case and control groups was done using two-tailed unpaired student t test for continuous variables and the Pearson's chi-square test for categorical variables. Correlations between normally distributed variables were done using Pearson correlation coefficient. p value < 0.05 was considered significant for all tests. Results: Female gender predominated the studied group (83.7%). The mean age of our population was 32.6 ± 6.7.Both groups were age and gender matched. All patients were neither diabetic nor hypertensive. Both groups had comparable degree of mitral stenosis. There was no statistical difference in LAV between both groups. However, PEF using Prolate-ellipsoid method was significantly lower in the case group (p=0.017). Conclusion: LA phasic indices may be better indicator of LA dysfunction than conventional LAV. LA PEF may be a predictor of thrombus formation and subsequent embolization in rheumatic MS and NSR.

Abstract

Objective: To assess left ventricular (LV) twist by three-dimensional speckle tracking imaging (3D-STI) in a pacing induced heart failure canine model with left bundle-branch block (LBBB) undergoing cardiac resynchronization therapy (CRT). Methods: After induction of left bundle branch block by radiofrequency ablation, rapid right ventricular pacing (RVP) at 200 beats/min was utilized in 22 adult beagle dogs for 6 weeks to induce heart failure. Then 15 dogs received CRT for 4 weeks and others were treated as control. Apical full-volume acquisition of the LV was obtained in conscious animals at baseline, the end of 6-week RVP and the end of 4-week CRT. Peak LV systolic twist (Ptw) and torsion (Ptor) along with peak apical and basal rotation were automatically calculated by Tom-Tec 4D LV Analysis 3.0 software to identify the ideal parameter in predicting treatment response of CRT. Results: After 4 weeks of CRT, LVEF increased [(31.97 ± 1.47) vs. (37.47 ± 3.60)%, p=0.002] and LVESV decreased [(24.13 ± 3.72) vs. (21.87 ± 3.15)ml, p=0.007] significantly in dogs with heart failure. By shortening the delay of basal rotation [(23.73 ± 9.98) vs. (17.87 ± 5.94)ms, p=0.009], CRT improved peak LV systolic twist [(6.88 ± 0.99) vs. (8.03 ± 0.63)°, p=0.008] and torsion [(1.21 ± 0.36) vs. (1.98 ± 0.39)°/cm, p=0.010] instead of peak apical [(5.97 ± 0.57) vs. (6.13 ± 0.61)°, p=0.103] and basal rotation [(2.08 ± 0.45) vs. (2.13 ± 0.46)°, p=0.469]. CRT treatment response, defined as improvement of LVESV≥15%, was observed in 9 dogs. Significant difference was found in Ptw [(7.43 ± 0.61) vs. (6.06 ± 0.89)°, p=0.016] and Ptor [(1.43 ± 0.45) vs. (0.67 ± 0.36)°/cm, p=0.042] between responders and nonresponders. The cut-off values derived from receiver-operating characteristic curve analysis were 6.73° for Ptw and 1.00°/cm for Ptor with satisfying sensitivity as 89% and 85%, specificity as 83% and 84%, respectively. Conclusions: CRT improved LV systolic twist and reversed LV remodeling by reconciling basal with apical rotation. Peak twist and torsion evaluated by 3D-STI demonstrated potential prediction value for treatment response of CRT.
