The effect of candesartan on pentraxin-3 plasma levels as marker of endothelial dysfunction in patients with essential arterial hypertension.

BACKGROUND: In the last decades, the studies performed on the field of endothelial dysfunction confirmed the fact that the starting point of this pathology is the inflammation. Several inflammatory biomarkers had been discovered and studied, ones showing systemic inflammation, and others being more specific biomarkers and showing the local inflammation. Pentraxin-3 (PTX3) is a new inflammatory biomarker, from the same family as high-selectivity C-reactive protein (hs-CRP), but it is a more specific biomarker, due to its local production: the endothelial cells and not the liver like in the case of hs-CRP. AIMS: Several antihypertensive classes of drugs seem to have a positive impact on reducing the local endothelial inflammation, beyond their effect of lowering the blood pressure, so this study aims to analyze the effect of candesartan on the two inflammatory biomarkers: PTX3 and CRP, compared with other antihypertensive drugs, in hypertensive patients with endothelial dysfunction. METHODS: A total of 365 patients were included in the study: 127 hypertensive patients were under treatment with candesartan, 134 patients were under treatment with other hypotensive medication (beta blockers, calcium channel blockers, and diuretics), both groups with controlled values of blood pressure, and 104 were normotensive persons. Classical methods of assessing the endothelial function were correlated with these biochemical markers. RESULTS: The patients treated with candesartan had a significant lower value of PTX3 and hs-CRP, compared with those under treatment with other antihypertensive medication as follows: PTX3: 0.61 ± 0.49 vs 0.95 ± 1.04 ng/ml, P = 0.006 and hs-CRP: 0.19 ± 0.20 vs 0.20 ± 0.22 mg/dl, P = 0.54. CONCLUSIONS: Candesartan decreases PTX3 and hs-CRP plasma levels more powerful than other classes of antihypertensive drugs (beta blockers, calcium channel blockers, and diuretics), so we may assume that candesartan has a more potent action in reversing endothelial dysfunction and that it offers a higher vascular protection than other classes of antihypertensive drugs. We are suggesting that this new biochemical marker, PTX3, might be better and more specific marker for endothelial dysfunction, than hs-CRP.

Psychopathology and psychotherapeutic intervention in diabetes: particularities, challenges, and limits.

Diabetes is a problem of great public health importance, creating a considerable burden to the affected individuals and society. The psychological approach of this disease implies the early acknowledging of behavioral symptoms and the construction of effective psychotherapeutic interventions. Regarding the psychological symptoms, cognitive malfunctions in diabetes include a slowing of information processing, attention, memory, and concentration, which, in turn, can significantly diminish motivation for therapy, compliance, and ability for self-care. Restrictions pertaining to daily activities, risks of treatment itself and the perceived inability to control the disease can furthermore reduce the perceived quality of life of these patients. Depression can complicate the picture, by a supplementary decrease in compliance and an increase of care expenses. A proper management of diabetes involves a joint action of the patient, physician, and the psychologist. A better self-care can include commuting from passive to active coping, getting informed, maintaining realistic hopes, and long-term thinking. Physicians can express more consistent empathy, thereby increasing confidence. A substantial gain can be brought by considering variables involved in modulating compliance (e.g. the patient's representations of gains and losses, group norms, ability vs. desire of control). Psychotherapeutic interventions include techniques such as counseling, cognitive-behavioral therapy, relaxation, hypnosis, and family therapy.

The management of external marketing communication instruments in health care services.

In order to become known and attract consumers, a health care organization has to develop suitable external communication campaigns. Consequently, management instruments are employed to effectively evaluate the success of a campaign. The BCG Matrix, SWOT analysis and the Gantt Diagram were used in this paper to ensure the consistency and accuracy of the external communication process at an empirical level.

Market policy as an innovative element of marketing in the Romanian healthcare services - an approach focused on the patient.

The orientation towards one of the marketing policies with a major impact in organizations providing healthcare services, requires a careful analysis of the needs and aspirations of customers, targeting those patients whose needs the service organization can achieve through the existing resources at the respective health facility, finding the most effective way of achieving benefits associated with reduced costs to maximizing profits, placing the offers for medical services required by the patients on the market, as well as promptly reacting and acting to the changes of health services market which is constantly evolving through a flexible organizing and functioning structure, connected to the financial needs of the patients.

Superior digestive tract side effects after prolonged treatment with NSAIDs in patients with osteoarthritis.

INTRODUCTION: Anti-inflammatory drugs (NSAIDs) represent one of the classes of drugs commonly recommended for patients with osteoarthritis. These drugs have side effects that sometimes affect the digestive tract. PATIENTS AND METHODS: 30 patients with either axial or peripheral osteoarthritis, hospitalized between January 2013 and January 2015 in the Rehabilitation Clinic of the Clinical Emergency County Hospital of Craiova, were followed. All the patients included had upper gastrointestinal endoscopy performed, excluding patients who had a history of gastritis, endoscopically demonstrated ulcer or those with a history of gastrointestinal dyspeptic phenomena. RESULTS: The endoscopic examination found acute erosive gastritis in eight cases, gastric ulcer (four cases) and duodenal ulcer (six cases). No serious complications were encountered. Four patients had no clinical manifestations with endoscopic expression. Lesions were mainly mild esophagitis (Grade I) and only in three cases, esophagitis grade II or III was found. Twelve patients (40%) had Helicobacter pylori infection and had endoscopic changes (gastric ulcer, duodenal ulcer, or gastric lesions). CONCLUSIONS: The adverse effects of NSAIDs in patients with osteoarthritis vary in severity. Patient age significantly influences the severity of injuries. We have not found significant differences in the incidence of COX2 selective and non-selective NSAID-induced lesions. Pathogenic interaction between the NSAID and Helicobacter Pylori infection is most often a synergistic effect in the development of gastritis or gastroduodenal ulcer.

Pre-operative transthoracic real-time three-dimensional echocardiography for a better surgical strategy.

UNLABELLED: In this study we aimed to evaluate the three-dimensional (3D) transthoracic echocardiography (TTE) in the assessment of cardiac valve morphology. METHODS: Bidimensional (2D) and real-time 3D TTE was performed in 104 patients consecutive with cardiac catheterisation, prior to valve surgery. Using surgical findings as the gold standard, 2D and 3D TTE were compared for adequate recognition and accurate detection of morphology. A scoring protocol was used for recognition of the valvular segments (0= inadequate, 1 = adequate). RESULTS: Adequate echographic visualization of the valve segments was more frequently obtained by 3D than 2D TTE imaging (731/770 by 3D TTE vs. 693/770 by 2D TTE, p < 0.01). The valve leaflets segments were more clearly identified by 3D TTE rather than by 2D TTE (502/531 vs. 471/531, p <0.01). The assessment of commissures was similar by both methods (229/239 vs. 222/239, p=0.09). Total 3D TTE scores for mitral and aortic valves were significantly better than 2D ITE scores (mean score 12.91+/-1.62 by 3D vs 11.58+/-1.02 by 2D, p=0.02). This superiority of 3D TTE was irrespective of rhythm (p <0.05 for both sinus rhythm and atrial fibrillation). Using surgical classification of valvular disease as gold standard, the sensibility and specificity were 91% and 84 % for 3D TTE, and 85% and 77% for 2D TTE, respectively. CONCLUSIONS: Real-time 3D was superior to 2D TTE forthe accurate localization and identification of valvular pathology, irrespective of heart rhythm.

The influence of left bundle branch-block and cardiac dyssynchrony on 2D-strain parameters in patients with heart failure complicating ischemic cardiomyopathy.

UNLABELLED: Coronary artery disease is the underlying cause in approximately two-thirds of patients with heart failure. Torsional and longitudinal deformations are essential components of left ventricular (LV) performance. Electric conduction defects can reduce LV ejection fraction (LVEF) and decrease cardiac output. AIM: To investigate the influence of left bundle branch-block (LBBB) and cardiac dyssynchrony on 2D-strain parameters in patients with HF complicating ischemic cardiomyopathy. METHODS: We analyzed 106 consecutive patients with HF complicating ischemic cardiomyopathy, in sinusal rhythm. LV strain, LV twist and LV torsion were measured by echocardiographic 2D-strain imaging. LV dyssynchrony was assessed using validated tissue Doppler parameters. Patients were divided into three groups: HF with normal LVEF (group 1), HF with reduced LVEF without LBBB (group 2) and with LBBB (group 3). RESULTS: LVEF, LV strain, LV torsion and LV twist were significantly better in group 1 (each p < 0.01). In group 3, LV torsion and LV twist were significantly lower compared to group 2 (0.80 +/- 0.4 vs. 1.21 +/- 0.23 degrees/cm, p = 0.007, and 5.18 +/- 2.4 vs. 8.31 +/- 1.5 degrees, p = 0.004, respectively), but LV strain and LVEF were not different between group 3 and 2 (-4.91 +/- 2.3 vs. -6.28 +/- 1.8%, p = 0.056, and 30.6 +/- 8.8 vs. 34.4 = 8.3%, p = 0.11, respectively). Cardiac dyssynchrony induces a reduction of all 2D-strain analyzed parameters (each p < 0.05). CONCLUSION: In HF complicating ischemic cardiomyopathy, LBBB and cardiac dyssynchrony induce a reduction of LV strain, torsion and twist. In patients with reduced LVEF, LBBB induces predominantly a significant reduction ofLV torsion and LV twist, while LV strain was apparently not influenced.

Left atrial surface cut point to detect trapezoidal shape for characterisation of atrial anatomical remodeling.

BACKGROUND: Complete geometrical and shape characterization of left atrium has not been performed. Ellipse formula has been proved to underestimate the real LA volume. The aim of the study is to analyze the relation between LA area and shape in order to predict their value in the assessment of the severity of anatomical remodeling. METHODS: 216 consecutive patients (pts) aged 53 +/- 27 years were included. The following parameters were assessed: LA dimensions (LAd=M-mode, parasternal long axis, LAt and LA1 are the measurements of short- and long-axis in apical four chamber view), LA surface in apical four chamber view (LAs). A new measurement was introduced, the basal dimension of the LA (LAb) as the maximal transverse distance at the base of LA apical four chamber view. LA measurements were calculated at end-systole (maximal). Trapezoidal LA shape was defined if transverse dimension < basal dimension. RESULTS: LAs ranged 10.5-54.5 cm2. Trapezoidal LA was found in 149 pts. ROC curve for prediction trapezoidal LA showed a 0.89 area under the curve. The analysis demonstrates a cutoff value of 22.3 cm2 for LAs to detect trapezoidal shape with a sensitivity of 85% and specificity of 82.5%. The simple regression analysis demonstrated a statistically significant linear correlation between LAd and LAs (r2=0.63, p<0.0001) but LA1 was better correlated with LAs (r2=0.7, p<0.0001). Trapezoid LA with atrialization of the pulmonary veins and predominant dilatation of bazal atrium than annular side may explain underestimation of LA volume using ellipse formula. CONCLUSION: LAs is a reliable parameter and may be the best choice to estimate LA dilatation; LAs is related to shape remodeling; LA1 is a better parameter than LAd for estimating LA dilatation and complete characterization of LA remodeling should include shape definition and LAb.

Dual renin angiotensin system blockade in patients with acute myocardial infarction and preserved left ventricular systolic function.

UNLABELLED: The activation of the renin-angiotensin system (RAS) is a major determinant of ventricular remodeling. We prospectively assessed whether the dual RAS blockade (angiotensin II AT 1-receptor blocker and angiotensin-converting enzyme inhibitor therapy) in patients with acute myocardial infarction (AMI) who were treated by primary percutaneous coronary intervention (PCI) and stenting provides benefit on the improvement of the left ventricle function. A secondary aim is to demonstrate that triple therapy with angiotensin-converting enzyme (ACE) inhibitors, angiotensin II AT 1-receptor blockers (ARBs) and beta blockers does not increase cardiovascular morbidity, cardiovascular mortality and all cause mortality. METHODS: We investigated 44 patients with AMI with ST elevation undergoing primary PCI and stenting. All patients received standard therapy including an ACE inhibitor and a beta blocker. We divided the patients into two groups, A and B. Valsartan was added to the standard therapy within the first 6 hours from the onset of AMI in group A. We assessed cardiovascular and all cause mortality, incidence of major acute coronary events (MACE), incidence of non-fatal AMI, the evolution of left ventricle ejection fraction (LVEF), wall motion score index (WMSI) and left ventricle end-systolic and end-diastolic diameters. The follow-up period was one year. RESULTS: There were no statistically significant differences between groups regarding cardiovascular and all cause mortality, incidence of MACE, incidence of non-fatal MI. LVEF significantly increased at 1 year in both groups. In both groups the reduction of end-systolic and end-diastolic diameters at 1 year was statistically significant. Echocardiographic findings demonstrated also a significant decrease of WMSI at 1 year in both groups. CONCLUSIONS: The dual renin-angiotensin system blockade (ARBs and ACE inhibitor) has proved its beneficial effect on the improvement of left ventricular function, without increasing cardiovascular mortality and incidence of non fatal myocardial infarction (MI) in patients with AMI treated by primary PCI and stenting within a 1 year follow-up period.

Is age correlated with dynamic atrial decremental conduction properties?

UNLABELLED: Atrial fibrillation (AF) has been associated with premature beats and decreased atrial conduction velocities. On the other hand, prevalence of AF is increased in the elderly. The aim is to evaluate and analyze the relation between age, atrial size and a new index of dynamic interatrial conduction time (iaCT) in a homogeneous population of patients (pts) with structurally normal heart without AF. METHODS: 45 patients (pts) without structural heart disease aged 53 +/- 20 years referred for electrophysiologic study were analyzed. To examine the atrial electrophysiologic characteristics we studied interatrial conduction time (iaCT), double potentials and fragmented atrial activity during premature stimulation of high right atrium; prior to investigation, all antiarrhythmic drugs were withdrawn for an appropriate period of time. The following parameters were assessed: baseline iaCT (iaCTb) between high right atrium (HRA) and distal coronary sinus (CS), iaCT during HRA pacing S1S1 600ms (iaCTS1), maximum prolongation of iaCT during S2 and S3 delivery (iaCTS2, iaCTS3). We calculated a derived parameter: maximum prolongation iaCT/decremental index (DI)= iaCT S3-ia CTS1/iaCTS1%. The following echocardiograhic parameters were assessed: left atrial dimensions and surface (LAs), right atrial dimension and surface (RAs), total atrial surface (TAs=LAs+RAs) and left atrial volume (LAv) calculated using ellipse formula. RESULTS: iaCT ranged from 42 to 87ms; DI ranged from 16 to 52%. Simple regression analysis demonstrated a statistically significant linear correlation between the age of pts and HRA DI (r = 0.76, r2 = 0.55, p <0.0001). A trend toward a significant correlation was found between TAs and DI (r=0.64, r2=0.41, p<0.0001) LAv and DI (r=0.59, r2=0.35, p<0.0001). No significant correlation was found in this group between age and iaCT. Atrial double potentials and fragmentated electrograms were recorded using HRA stimulation in CS leads in 7 pts (15%) all aged >35 years. Pts were divided into two groups: 17 pts with normal electrophysiologic findings and 28 pts with junctional reentrant tachycardia. There were no significant differences between subgroups concerning the main studied parameters. CONCLUSIONS: This study shows a direct better correlation for age than atrial size in the relation with the dynamic behaviour interatrial conduction, suggesting that higher incidence in AF in the elderly might be also a consequence of the higher incidence of atrial conduction disturbances.

Echocardiographic evidences of increased left ventricular pressure and atrial dilatation in patients with drug-resistant paroxystic atrial fibrillation and structurally normal heart.

UNLABELLED: Global myocardial index (GMI) has been significantly related to left ventricular filling pressure. We hypothesized that GMI and echographic indicators of atrial dilatation were significantly different in pAF pts compared to normals. METHODS: 39 patients (pts) without structural heart disease, aged 52+/-10 years with pAF were compared to 36 control-matched pts aged 48+/-16 years. Following parameters were assessed: P-wave duration (Pd), GMI, left atrial dimensions (LAd=M-mode, parasternal, LAt and LAI are measurements of short and long-axis apical four chamber view), surface (LAs), volume (LAv), total ejection fraction (LA EF), right atrial dimension (RAd) and surface (RAs), total atrial surface (TAs=LAs+RAs). LAv was calculated using ellipse formula pi/6 (LAdxLAlxLAt). RESULTS: There was no difference between the 2 groups concerning Pd (p=0.1), LA EF (p=0.23), LAd (p=0.08) and LAt (p=0.06) while the rest of the parameters were significantly higher in pAF pts: GMI: 0.5+/-0.17 vs 0.36+/-0.06 (p=0.001); LAI: 5.4+/-0.5 vs 4.5+/-0.3 cm2 (p=0.001); LAs was founded increased in pAF pts (20.6+/-5.7 vs 16.3+/-2.1 cm2, p=0.001); TAs: 40.6+/-6.9 vs 30.6+/-5.1 cm2, p=0.0001; LAv: 51.6+/-10.4 vs 37.2+/-9.3 ml (p=0.0001). CONCLUSIONS: Although apparently without structural heart disease, pAF pts presented evidence of increased filling pressions in left ventricle and indirect markers of atrial stretch. The role of increased intra-atrial pressure in pts pFA and predictive value of these parameters need to be evaluated in a larger number of patients.

Absence of correlation between QRS duration and echographic parameters of ventricular desynchronization. Can we still trust the electrocardiographic criteria?

UNLABELLED: The aim of the study was to assess if echographic ventricular desynchronization parameters measured in patients with dilated cardiomyopathy (DCM) and severe heart failure are correlated with the duration of the QRS on surface electrocardiogram. METHODS: This study included 51 pts aged 58.8 +/- 7.4 years with idiopathic DCM. The following parameters were measured: QRS duration; effective contraction time (ECT) measured as the interval between QRS onset and closure of aortic valve, interventricular delay (IVD) measured as the time between onset of aortic and pulmonary flow, left ventricular mechanical delay (LVD) as the time from maximal interventricular septum contraction and posterior wall contraction, posterior (P), lateral (L) and posterolateral (PL) wall delays, as the time from QRS onset to maximal wall contraction. Regional postsystolic contraction was defined in a given wall as the difference (contraction delay - ECT)> 50ms. RESULTS: 29 pts presented complete LBBB, 22 pts had QRS duration < 120 ms. 39 pts had a postsystolic contraction of the PL wall (32 pts of the L wall and 26 pts of the P wall). 16 pts with QRS duration <120 had a postsystolic contraction of the PL wall (as for the LBBB the rest of 39 pts). In 40 pts the sequence of regional ventricular contraction was: P-L-PL wall (16 pts with QRS<120). LVD was > 100 ms in 36 pts (26 pts with LBBB and 10 with QRS<120). 27 of pts with LBBB and 6 with QRS <120 ms presented IVD> 30ms. There was no correlation between the QRS duration and the parameters listed above. CONCLUSIONS: In DCM pts there is no correlation between the duration of the QRS and echocardiographic parameters of ventricular desynchronization. Mechanical ventricular de-synchrony can be observed in patients with QRS duration < 120 ms.

Global myocardial index in patients with multisite pacing.

UNLABELLED: Global myocardial index (GMI) is a sensitive echocardiographic indicator of overall cardiac function. The aim of this study was to compare the GMI changes induced by Bi-V pacing to the variations in clinical, electrocardiographic and echocardiographic parameters currently used for evaluation of ventricular resynchronization in order to test the potential marker of positive clinical response. PATIENTS AND METHODS: This study included 35 consecutive patients (pts), aged 65.7+/-7.5 years, implanted with an endocavitary Bi-V pacemaker for drug refractory severe heart failure. NYHA class was evaluated before implantation and at day 30. QRS duration (QRSd), echocardiographic interventricular delay (IVD), and GMI were determined in the paced and non-paced situation at day 1, 7 and 30 after implantation. RESULTS: NYHA class improved from 3.5+/-0.3 to 2.4+/-0.4 (p<0.01). GMI improved significantly (p<0.0001) after Bi-V in all pts from 1.25 +/- 0.5 to 0.77 +/- 0.34 and remained stable all along the study. GMI decrease (dGMI) in pts with NYHA functional class improvement > 0.5 was 0.52 +/- 0.16while dGMI in pts with NYHA functional class improvement < or = 0.5 was 0.21+/- 0.19. dGMI was statistically correlated with IVD shortening (r=0.67, p<0.0001) but not with QRSd shortening. CONCLUSION: The GMI improves during Bi-V pacing, mostly in responders pts and the improvement remains unchanged after the implant. The GMI decrease induced by Bi-V pacing is correlated with the IVD shortening and NYHA functional class improvement.

Assessment of treatment with orotate magnesium in early postoperative period of patients with cardiac insufficiency and coronary artery by-pass grafts (ATOMIC).

The benefit of the treatment with magnesium orotate (magnerot) was assessed in a randomised, single blind and placebo controlled study. Respecting the inclusion criteria were selected 32 patients with ischemia chronic failure in early postoperative period after CABG. The main improvements induced by magnesium orotate are the increase in exercise capacity (distance ambulated during 6 minutes walk test and ergospirometric parameters) and the reduction of ventricular premature beats. The treatment was well tolerated and the adverse reactions were not significant. The study strongly suggests the benefit of magnesium orotate added to classical antiischemic therapy in the complex management of coronary patients after CABG.

[Posttraumatic pseudoaneurysm of the axillary artery after anterior dislocation of the shoulder: a case report]. / Pseudoanevrism posttraumatic al arterei axilare, dupa luxatie anterioara a umarului: prezentare de caz.

We present a case of a young patient, 44 years old, with a pseudoaneurysm of the axillary artery after anterior shoulder dislocation. The early diagnosis of axillary artery lesions after trauma is difficult in some cases. It's important to mention the possibility of accidental vascular surgery during reduction of the shoulder dislocation. In consequence, in all patients with a penetrating or blunt trauma of the shoulder is required a neurological and vascular examination; in any suspicions, an additional arteriography and computer tomography is indicated. Early repairs of vascular and neurological lesions are very important for the outcome of these patients.

Left atrial spontaneous echo contrast as a predictor of systemic arterial embolization in rheumatic mitral valve disease: a transesophageal echocardiographic study.

The relationship between systemic arterial embolization and left atrial spontaneous echo contrast (LASEC) was investigated in 90 consecutive patient with rheumatic mitral valve disease (52 patients had predominant mitral stenosis, 14 had significant mitral regurgitation and 24 with xenograft mitral valve replacement), during a 2-year period. LASEC was defined as the presence of dynamic echos (smoke-like) curling up in a circular pattern within the left atria, by transesophageal echocardiography (TEE). LASEC was observed in 27 patients (group A) and was absent in 63 patients (group B). Group A patients showed a higher frequency of left atrial thrombi or history of previous embolization than those in group B (59.2% vs. 7.3%; p < 0.001). Group A patients also had a higher frequency of recent (10 days before TEE study) and remote (more than 10 days before TEE study) embolization than did group B patients (recent: 22.2% vs. 1.6%; p < 0.001; remote: 11.1% vs. 4.7%, p < 0.001). Thus patients with LASEC had a significantly higher risk for thromboembolism and TEE is a useful modality to identify this subset of patients with rheumatic mitral valve disease.

Electrophysiologic noninvasives parameters in patients with sick sinus syndrome and syncopal attacks.

21 patients accusing previous syncopal attacks, without myocardial infarction, preexcitation syndrome or severe cardiac failure were submitted to a 24 hrs Holter monitoring with 10 min. of esophageal electrocardiogram. Nine patients were considered as cases of sinus bradycardia (mean HR = 49.5 +/- 4.4 b/min). Other 12 patients with normal basic sinus rhythm were admitted for ventricular premature beats (HR = 65.5 +/- 8.7 b/min.). Fourier transformation analysis (mean method, linear interpolation) was used for determination of the heart rate variability (HRV) and other two variables: variation range (VR)--(longest-shortest cycle/mean basic sinus cycle, %) and differences of sinus cycle length (DSCL = maximal difference of any two consecutive sinus cycle, ms). In all the 9 patients with low sinus rhythm and in 7 patients with normal basic sinus rhythm, at least one episode of critical bradycardia (under 45 b/m) was observed. In 3 of the 9 patients with sinus bradycardia at least two episodes of nonsustained ventricular tachycardia were observed. In all the 12 patients with ventricular premature beats, many episodes of nonsustained ventricular tachycardia were registered. In all the 21 studied patients low and very low frequency HRV was observed. The VR and DSCL presented a significant dependence on age, but this relationship was weaker than the established limits of normality. In the cases of sick sinus syndrome with sinus bradycardia and/or severe ventricular tachyarrhythmias, the noninvasive Holter analysis of HRV can determine the correct diagnosis and indications for permanent cardiac pacing and antiarrhythmic drug therapy.
