RESUMEN

BACKGROUND: Septic shock is a severe form of sepsis marked by hypotension with an ominous outcome despite the introduction of modern intensive care. The aim of the present study is to obtain a panel with biomarkers, echocardiographic and vascular parameters to better risk stratify patients and identify those at higher risk of ominous outcome. METHODS: Between May 2013 and April 2016, 35 consecutive patients admitted at the Intensive Care Unit (ICU) of ASST Great Metropolitan Hospital Niguarda with the diagnosis of severe sepsis or septic shock were enrolled. All patients underwent rest echocardiography and several circulating biomarkers of myocardial damage or oxidative stress. RESULTS: The multivariate Cox's proportional hazard model showed that the only independent prognostic predictor for 30-day mortality was the angiopoietin-2, (HR 1.017, 95% CI 1.000-1.034; P = 0.049). An angiopoietin-2 concentrations ≥ of 33,418 pg/mL was identified as the optimal threshold for the discrimination between survivors and non survivors at the time of admission in ICU, with a sensitivity of 80% and a specificity of 68%. CONCLUSIONS: Septic shock has a poor in-hospital outcome even when the best of care is implemented. Among the biochemical parameters angiopoietin was able to identify patients at risk of death. The lowest the value at admission, the highest the risk of in-hospital death. No echocardiographic nor vascular parameter was able to predict outcome in this setting.

RESUMEN

INTRODUCTION: The WHO declared 2019 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a public health emergency of international concern. The National and Regional Health System has been reorganized, and many oncological patients died during this period or had to interrupt their therapies. This study summarizes a single-centre experience, during the COVID-19 period in Italy, in the treatment of brain metastases with Gamma Knife stereotactic radiosurgery (GKRS). METHODS: We retrospectively analysed our series of patients with brain metastases who underwent GKRS at the Niguarda Hospital from February 24 to April 24, 2020. RESULTS: We treated 30 patients with 66 brain metastases. A total of 22 patients came from home and 8 patients were admitted to the emergency room for urgent neurological symptoms. Duration of stay was limited to 0-1 day in 17 patients. We chose to treat a cluster of 9 patients, whose greater lesion exceeded 10 cm3, with 2-stage modality GKRS to minimize tumour recurrence and radiation necrosis. CONCLUSION: Due to the COVID-19 pandemic, the whole world is at a critical crossroads about the use of health care resources. During the COVID-19 outbreak, the deferral of diagnostic and therapeutic procedures and a work backlog in every medical specialty are the natural consequences of reservation of resources for COVID-19 patients. GKRS improved symptoms and reduced the need for open surgeries, allowing many patients to continue their therapeutic path and sparing beds in ICUs. Neurosurgeons have to take into account the availability of stereotactic radiosurgery to reduce hospital stay, conciliating safety for patients and operators with the request for health care coming from the oncological patients and their families.

RESUMEN

BACKGROUND: Clinical evaluation of central venous pressure is difficult, depends on experience, and is often inaccurate in patients with chronic advanced heart failure. We assessed the ultrasound-assessed internal jugular vein (JV) distensibility by ultrasound as a noninvasive tool to identify patients with normal right atrial pressure (RAP ≤7 mm Hg) in this population. METHODS: We measured JV distensibility as the Valsalva-to-rest ratio of the vein diameter in a calibration cohort (N=100) and a validation cohort (N=101) of consecutive patients with chronic heart failure with reduced ejection fraction who underwent pulmonary artery catheterization for advanced heart failure therapies workup. RESULTS: A JV distensibility threshold of 1.6 was identified as the most accurate to discriminate between patients with RAP ≤7 versus >7 mm Hg (area under the receiver operating characteristic curve, 0.74 [95% CI, 0.64-0.84]) and confirmed in the validation cohort (receiver operating characteristic, 0.82 [95% CI, 0.73-0.92]). A JV distensibility ratio >1.6 had predictive positive values of 0.86 and 0.94, respectively, to identify patients with RAP ≤7 mm Hg in the calibration and validation cohorts. Compared with patients from the calibration cohort with a high JV distensibility ratio (>1.6; n=42; median RAP, 4 mm Hg; pulmonary capillary wedge pressure, 11 mm Hg), those with a low JV distensibility ratio (≤1.6; n=58; median RAP, 8 mm Hg; pulmonary capillary wedge pressure, 22 mm Hg; P<0.0001 for both) were more likely to die or undergo a left ventricular assist device implant or heart transplantation (event rate at 2 years: 42.7% versus 18.2%; log-rank P=0.034). CONCLUSIONS: Ultrasound-assessed JV distensibility identifies patients with chronic advanced heart failure with normal RAP and better outcomes.

RESUMEN

Catheter-based revascularization procedures were developed as an alternative to systemic thrombolysis for patients with intermediate-high- and high-risk pulmonary embolisms. USAT IH-PE is a retrospective and prospective multicenter registry of such patients treated with ultrasound-facilitated, catheter-directed thrombolysis, whose preliminary results are presented in this study. The primary endpoint was the incidence of pulmonary hypertension (PH) at follow-up. Secondary endpoints were short- and mid-term changes in the echocardiographic parameters of right ventricle (RV) function, in-hospital and all-cause mortality, and procedure-related bleeding events. Between March 2018 and July 2023, 102 patients were included. The majority were at intermediate-high-risk PE (86%), were mostly female (57%), and had a mean age of 63.7 ± 14.5 years, and 28.4% had active cancer. Echocardiographic follow-up was available for 70 patients, and in only one, the diagnosis of PH was confirmed by right heart catheterization, resulting in an incidence of 1.43% (CI 95%, 0.036-7.7). RV echocardiographic parameters improved both at 24 h and at follow-up. In-hospital mortality was 3.9% (CI 95%, 1.08-9.74), while all-cause mortality was 11% (CI 95%, 5.4-19.2). Only 12% had bleeding complications, of whom 4.9% were BARC ≥ 3. Preliminary results from the USAT IH-PE registry showed a low incidence of PH, improvement in RV function, and a safe profile.

RESUMEN

BACKGROUND: Patients with systemic sclerosis (SSc) are at risk for developing pulmonary hypertension, which is associated with a poor prognosis. Exercise Doppler echocardiography enables the identification of exercise-induced increase in pulmonary artery systolic pressure (PASP) and may provide a thorough noninvasive hemodynamic evaluation. AIM: The aim of this study was to evaluate the clinical and echocardiographic determinants of exercise-induced increase in PASP in a large population of patients with SSc. METHODS: We selected 164 patients with SSc (age 58 ± 13 years, 91% female) with normal resting PASP (<40 mm Hg) who underwent a comprehensive 2-dimensional and Doppler echocardiography and graded bicycle semisupine exercise Doppler echocardiography. Pulmonary artery systolic pressure, cardiac output, and pulmonary vascular resistance (PVR) were estimated noninvasively. Cutoff values of PASP ≥50 mm Hg and PVR ≥3.0 Wood Units at peak exercise were considered a significant exercise-induced increase in PASP and PVR, respectively. RESULTS: Sixty-nine (42%) patients showed a significant exercise-induced increase in PASP. Among them, peak PVR ≥3 Wood Units was present only in 11% of patients, about 5% of the total population. Univariate analysis showed that age, presence of interstitial lung disease, and both right and left diastolic dysfunction are predictors of peak PASP ≥50 mm Hg, but none of these parameters predict elevated peak PVR. CONCLUSIONS: Exercise-induced increase in PASP occurs in almost one-half of patients with SSc with normal resting PASP. Peak exercise PASP is affected by age, interstitial lung disease, and right and left ventricular diastolic dysfunction and, only in 5% of the patients, is associated with an increase in PVR during exercise, suggesting heterogeneity of the mechanisms underlying exercise-induced pulmonary hypertension in SSc.

RESUMEN

BACKGROUND: In cardiac AL amyloidosis, myocardial infiltration is typically associated with "low QRS voltages" at the 12-lead electrocardiogram (ECG). Although considered as one of the hallmarks of the disease, its reported prevalence varies from 45% to 70%, mainly because of nonhomogeneous definitions. METHODS: To identify the "low QRS voltage" parameter having the best diagnostic value in identifying cardiac amyloidosis, and to assess its possible prognostic role, ECG and echocardiographic data were collected at diagnosis in 337 consecutive never-treated AL patients (233 with, 104 without cardiac involvement). Prognosis was assessed after a median follow-up of 14.5 months. RESULTS: "Low QRS voltage" prevalence varied from 84.12% when using Sokolow-Lyon index ≤15 mm to 27.04% with the definition of low total voltages (QRS amplitude ≤5 mm in each peripheral and ≤10 mm in each precordial lead), the widely used definition of low peripheral voltages (≤5 mm in each peripheral lead) being able to identify 66.52% cardiac AL patients. The presence of "low peripheral voltages" was associated with a more severe cardiac involvement, and was able to differentiate Mayo stage II patients' survival (i.e., AL patients with intermediate prognosis). According to receiver operator characteristic (ROC) curve analysis, sensitivity and specificity were 58.72% and 80.00%, for a peripheral QRS amplitude ≤24.5 mm (the sum of QRS in all the 6 peripheral leads), and 76.26% and 65.00% for a Sokolow-Lyon index ≤11 mm. CONCLUSIONS: In cardiac AL amyloidosis the prevalence of low QRS voltages is highly dependent on the method used for defining this ECG alteration.

RESUMEN

BACKGROUND AND PURPOSE: To evaluate the prevalence and the prognostic implications of conduction delays in a large cohort of cardiac AL patients. METHODS: Echo Doppler and 12-lead ECG were collected in 344 consecutive patients in whom diagnosis of AL amyloidosis was concluded between 2008 and 2010. Patients were subdivided according to the presence (n = 240) or absence (n = 104) of cardiac involvement. RESULTS: When compared with patients without myocardial involvement, cardiac AL was associated with prolonged PQ, QRS, QT and QTc intervals (P < 0.05), and with higher prevalence of intraventricular blocks (27.5% vs. 16.5%, P < 0.05), that was associated with higher wall thickness, worse diastolic and regional systolic function, higher NT-proBNP values (all P < 0.05), and higher mortality (P = 0.0001; median follow-up: 402 days). CONCLUSION: Intraventricular conduction delays have a negative prognostic impact in patients with cardiac AL amyloidosis. Their presence should not be overlooked in the diagnostic workup, prompting a more accurate cardiological support.

RESUMEN

Hereditary transthyretin amyloidosis is a severe, adult-onset autosomal dominant inherited systemic disease predominantly affecting the peripheral and autonomic nervous system, heart, kidney, and the eyes. We present a case of a Caucasian 65-year-old man with cardiac amyloidosis and the homozygous mutation Val142Ile (classically, Val122Ile) in the transthyretin gene. We provide a genotype-phenotype correlation regarding the genetic status of both heterozygous and homozygous individuals and their clinical conditions at the time of genetic testing.

RESUMEN

BACKGROUND AND AIM: Thromboembolic events due to left atrial appendage (LAA) thrombosis are the main complication of non-valvular atrial fibrillation (NVAF). Although anticoagulants are effective in patients with NVAF, a minimal residual thromboembolic risk persists. Little is known about the prevalence of LAA thrombus and the rate of resolution after the recommended period of anticoagulation therapy, including vitamin K antagonists (VKA), heparin, and non-vitamin K antagonist oral anticoagulants (NOACs). METHODS AND RESULTS: We aimed to study the prevalence of LAA thrombus in an unselected cohort of patients undergoing transesophageal echocardiogram (TEE), and the determinants of LAA thrombus resolution. We retrospectively analyzed 8888 consecutive TEEs performed over five years in two high-volume centers and included all patients with LAA thrombus. A total of 265 patients (3%) had an LAA thrombus. Among these, 97% presented with AF. Fifty-eight percent of patients were on anticoagulants at least three weeks before the diagnosis. After the LAA thrombus diagnosis, VKAs were prescribed in 52%, heparin in 18.5%, and NOAC in 27% of patients. Among the 183 patients with repeat TEE, performed at (25-75th) 39 days (21-84), 67% showed resolution of the LAA thrombus. Although the rate of thrombus resolution was higher in patients treated with NOACs (NOACs 71%, VKA 66%, Heparin 60%) the difference between anticoagulants was statistically non-significant (VKA, OR 0.9, p = 0.83; NOAC, OR 1.23, p = 0.42; heparin, OR 0.69, p = 0.35). Thus, NOACs were demonstrated to be at least as effective as other anticoagulants in the rate of LAA thrombus resolution. Upon multivariate-adjusted analysis, higher LAA emptying velocities were the only predictor of thrombus resolution. In conclusion, the majority of patients were already on anticoagulants. NOACs could be at least as effective as other anticoagulants, yielding an LAA thrombus resolution in two-thirds of patients. This may have clinical relevance, especially in patients undergoing cardioversion or catheter ablation.

RESUMEN

Purpose of our study was to assess the prevalence of hypertension mediated organ damage (HMOD) in healthy subjects with high-normal Blood Pressure (BP) comparing them with subjects with BP values that are considered normal (<130/85 mmHg) or indicative of hypertension (≥140/90 mmHg). Seven hundred fifty-five otherwise healthy subjects were included. HMOD was evaluated as pulse wave velocity (PWV), left ventricular mass index (LVMI), and carotid intima-media thickness (IMT) and plaque. When subjects were classified according to BP levels we found that the high-normal BP group showed intermediate values of PWV and higher values of IMT. This corresponds to intermediate prevalence of arterial stiffness, while there were no differences for increased IMT or carotid plaque. No subjects showed left ventricular hypertrophy. At multivariable analysis, the odds of having arterial stiffness or carotid HMOD in the high-normal group resulted not different to the normal group. In conclusion, in our otherwise healthy population, high-normal BP values were not related to aortic, carotid or cardiac HMOD.

RESUMEN

OBJECTIVES: The purpose of this study is to verify whether transcatheter aortic valve implantation (TAVI) determined changes in mitral valve (MV) function, in terms of mitral regurgitation (MR) and stenosis. BACKGROUND: Little data is available regarding the effects of TAVI on global MV function, often derived from analysis primarily focused on clinical and aortic related outcomes. METHODS: From May 2008 to March 2010, 73 patients with severe symptomatic aortic stenosis underwent TAVI with the CoreValve ReValving System. The study population consisted of 58 patients (27 males, mean age 82 ± 7 years) who underwent transthoracic echocardiography at least ≥1 month after implantation (mean follow-up 7.8 ± 5.4 months). RESULTS: In patients with a left ventricular dysfunction (ejection fraction, EF, <45%) at the baseline, EF significantly increased from 37 ± 6% to 48 ± 7% after TAVI (P = 0.003). Before TAVI, 42 patients had no or mild MR, 13 mild-to-moderate, and 3 moderate or moderate-to-severe. During follow-up, the MR degree was unchanged in the majority of patients (55%), 12% reduced, and 33% worsened. Variables associated with worsening in MR were depth of aortic prosthesis (P = 0.02 for the distance between the ventricular end and the right coronary cusp; P = 0.04 for mean distance right-left coronary cusps) and left atrium area at the baseline (P = 0.02). After TAVI, six patients (10%) developed mild or moderate mitral stenosis, often in a native valve with anterior calcifications. CONCLUSIONS: In the majority of patients no significant changes occurred in the degree of MR in native valve, but we found that if the aortic valve was deeply implanted in the left ventricle outflow tract, a worsening in MR can be observed. A mitral stenosis development must be sought in patients with heavy calcifications of the anterior leaflet.

RESUMEN

BACKGROUND: Most studies of amyloidotic cardiomyopathy consider as a single entity the 3 main systemic cardiac amyloidoses: acquired monoclonal immunoglobulin light-chain (AL); hereditary, mutated transthyretin-related (ATTRm); and wild-type transthyretin-related (ATTRwt). In this study, we compared the diagnostic/clinical profiles of these 3 types of systemic cardiac amyloidosis. METHODS AND RESULTS: We conducted a longitudinal study of 233 patients with clear-cut diagnosis by type of cardiac amyloidosis (AL, n=157; ATTRm, n=61; ATTRwt, n=15) at 2 large Italian centers providing coordinated amyloidosis diagnosis/management facilities since 1990. Average age at diagnosis was higher in AL than in ATTRm patients; all ATTRwt patients except 1 were elderly men. At diagnosis, mean left ventricular wall thickness was higher in ATTRwt than in ATTRm and AL. Left ventricular ejection fraction was moderately depressed in ATTRwt but not in AL or ATTRm. ATTRm patients less often displayed low QRS voltage (25% versus 60% in AL; P<0.0001) or low voltage-to-mass ratio (1.1+/-0.5 versus 0.9+/-0.5; P<0.0001). AL patients appeared to have greater hemodynamic impairment. On multivariate analysis, ATTRm was a strongly favorable predictor of survival, and ATTRwt predicted freedom from major cardiac events. CONCLUSIONS: AL, ATTRm, and ATTRwt should be considered 3 different cardiac diseases, probably characterized by different pathophysiological substrates and courses. Awareness of the diversity underlying the cardiac amyloidosis label is important on several levels, ranging from disease classification to diagnosis and clinical management.

RESUMEN

BACKGROUND: The right ventriculoarterial coupling (R-V/A), a measure of right ventricular systolic dysfunction (RVSD) adaptation/maladaptation to chronic overload, and consequent pulmonary hypertension, has been little investigated in nonischemic dilated cardiomyopathy (NIDCM). We examined the correlates of R-V/A and traditional echocardiographic indices of RVSD, over the spectrum of pulmonary hypertension and tertiles of mean pulmonary artery pressures (PAPm). METHODS: In 2016-2017, we studied 81 consecutive patients for heart transplant/advanced heart failure. Inclusion criteria were NIDCM, reduced ejection fraction (≤40%) and sinus rhythm. R-V/A was computed as the RV/pulmonary elastances ratio (R-Elv/P-Ea), derived from a combined right heart catheterization/transthoracic- echocardiographic assessment [right heart catheterization/transthoracic-echocardiographic (RHC/TTE)]. RESULTS: A total of 68 patients (mean age 64 ±â€Š7 years, 82% men) were eligible. After adjustments, R-Elv and P-Ea were higher in isolated postcapillary-pulmonary hypertension (Ipc-PH) than combined-pulmonary hypertension (Cpc-PH) (P = 0.004 and P = 0.002, respectively), whereas R-V/A progressively decreased over Ipc-PH and Cpc-PH (P = 0.006). According to PAPm increment, P-Ea congruently increased (P-Trend = 0.028), R-Elv progressively decreased (P-Trend<0.00)1, whereas R-V/A significantly worsened (P-Trend = 0.045). At the multivariable analysis, a reduced RV longitudinal function (TAPSE<17 mm) was positively associated with R-V/A impairment (<0.8) [odds ratio 1.41, 95% confidence interval (CI) (1.07--1.87), P = 0.015]. R-Elv and P-Ea showed good interobserver reliability [interclass correlation (ICC) 0.84, 95% CI (0.32--0.99), P = 0.012 and ICC 0.98, 95% CI (0.93--99), P < 0.001, respectively]. CONCLUSION: Among NIDCM HF patients, in a small cohort study, RHC/TTE-derived R-V/A assessment demonstrated good correlations with pulmonary hypertension types and RV functional status. These data suggest that R-V/A encloses comprehensive information of the whole cardiopulmonary efficiency, better clarifying the amount of RVSD, with good reliability.

RESUMEN

BACKGROUND AND PURPOSE: Radiation Induced Heart Disease (RIHD) represents a late effect of chest irradiation, contributing in increasing mortality rate in oncological patients by affecting pericardium, myocardium, valvs and coronaries. Currently, regarding the risk of Coronary Artery Disease (CAD), a cardiological screening involving exercise stress electrocardiography after 5-10 years from radiotherapy is advised. We sought to determine the rate of ischemia at exercise stress electrocardiography in a population of patients without cardiovascular risk factors who sustained radiotherapy, using a cohort of patients presenting with at least one cardiovascular risk factor as control group. DESIGN AND METHODS: A population of 115 patients who sustained chest irradiation (and associated chemotherapy), presenting without classic cardiovascular risk factors or typical symptoms suggesting CAD, was evaluated with exercise stress electrocardiography. 135 patients with at least one risk factor for cardiovascular disease candidate to stress testing for primary prevention or for atypical symptoms served as control group. RESULTS: The cohort of irradiated patients without classical cardiovascular risk factors is younger (48.7 ± 10.1 vs 60.5 ± 10.8 years, p < 0.001) and presents a lower percentage of males when compared with the control group. In this latter group 25.9% of subjects has diabetes, 62.9% dyslipidaemia, 67.4% hypertension and 19.2% actively smoke. Despite this important differences regarding classic cardiovascular risk factors, no significant differences were found in the number of positive exercise stress electrocardiography (10.4 vs 5.9%, p = ns). CONCLUSIONS: Chest irradiation represents a strong cardiovascular risk factor. In fact, prevalence of positive ECG-stress test is not different (nor higher and nor lower) in irradiated subjects without cardiovascular risk and not irradiated patients with classic cardiovascular risk.

RESUMEN

Treatment of overt form of hypertrophic cardiomyopathy (HCM) is often unsuccessful. Efforts are focused on a possible early identification in order to prevent or delaying the development of hypertrophy. Our aim was to find an echocardiographic marker able to distinguish mutation carriers without left ventricular hypertrophy (LVH) from healthy subjects. We evaluated 28 patients, members of eight families. Three types of mutation were recognized: MYBPC3 (five families), MYH7 (two families) and TNNT2 (one family). According to genetic (G) and phenotypic (Ph) features, patients were divided in three groups: Group A (10 patients), mutation carriers with LVH (G+/Ph+); Group B (9 patients), mutation carriers without LVH (G+/Ph-); Group C (9 patients), healthy subjects (G-/Ph-). Echocardiography examination was performed acquiring standard 2D, DTI and 2D-strain imaging. Global longitudinal strain (GLS) and global radial strain (GRS) at basal and mid-level were measured. GRS was significantly different between group B and C at basal level (32.18% ± 9.6 vs. 44.59% ± 12.67 respectively; p-value < 0.0001). In basal posterior and basal inferior segments this difference was particularly evident. ROC curves showed for both the involved segments good AUCs (0.931 and 0.861 for basal posterior and inferior GRS respectively) with the best predictive cut-off for basal posterior GRS at 43.65%, while it was 38.4% for basal inferior GRS. Conversely, GLS values were similar in the three group. 2D longitudinal strain is a valid technique to study HCM. Radial strain and particularly basal posterior and inferior segmental reduction could be able to identify mutation carriers in a pre-clinical phase of disease.

RESUMEN

INTRODUCTION: No data regarding the safety of continuous-flow left ventricular assist device (CF-LVAD) implantation in patients with previous MitraClip have been reported. Thus, it remains unknown whether an initial treatment strategy with MitraClip therapy might complicate future heart failure management in patients who are also considered for CF-LVAD. METHODS: We retrospectively identified 6 patients (median age of 62 years; 2 women) who had been treated with MitraClip, that were eventually implanted with a CF-LVAD (all Heartware HVAD) in 3 hospitals between 2013 and 2018. RESULTS: Patients were treated in 4 cases with 2 clips, and in 2 cases with 1 clip. Median time from MitraClip implantation to CF-LVAD implant was 282 days (interquartile range 67 to 493), and median time on CF-LVAD support was 401 days (interquartile range 105 to 492 days). Two patients underwent a heart transplant, 3 patients died on support, and 1 is alive on support. In all cases, there was a reduction of functional mitral regurgitation without MitraClip-related complications. CONCLUSIONS: Based on this small case series, implantation of a CF-LVAD appears safe in patients with a previously positioned MitraClip system, at least, with 1 or 2 clips in place, with no need for additional mitral valve surgery.

RESUMEN

Transcatheter aortic valve implantation has been designed to treat older patients affected by severe aortic stenosis who are considered high-risk surgical candidates because of multiple comorbidities. The least invasive approach for transcatheter aortic valves implantation should be considered the transfemoral retrograde route, because it is minimally invasive and is feasible with local anesthesia and mild sedation. Despite significant technical improvements in recent years, the transfemoral approach is contraindicated in cases of severe peripheral artery disease. We describe the first case of a Portico transcatheter aortic valve implantation system (St. Jude Medical, Minneapolis, MN) made through the distal axillary artery in a 90-year-old patient affected by severe aortic stenosis.

RESUMEN

OBJECTIVE: Annexin A5 (AnxA5) has been previously linked to the presence of carotid and cardiac target organ damage (TOD) in the context of heart failure and rheumatologic patients. However, information is scant in the context of hypertension. Aim of our study was to evaluate AnxA5 in treated hypertension patients compared with normotensive controls and to determine whether it is associated with vascular and heart TOD evaluated as arterial stiffness, carotid plaque and left ventricular hypertrophy. METHODS: We enrolled 123 consecutive treated hypertension and 124 normotensive controls. TOD was evaluated as pulse wave velocity (PWV, complior), left ventricular hypertrophy (echocardiography) and intima-media thickness and carotid plaque presence (ecographic methods). AnxA5 levels was dosed and compared in patients with and without hypertension and with and without TOD. RESULTS: With similar age hypertension patients showed higher SBP, DBP and AnxA5 levels (13.9 ±â€Š11.1 vs 10.1 ±â€Š8.4 ng/ml, P < 0.001) compared with controls. Regarding TOD hypertension showed higher PWV (8.5 ±â€Š1.8 vs 7.6 ±â€Š1.5 m/s, P < 0.001) and LVMI (121.7 ±â€Š29.3 vs 113.5 ±â€Š21.1 g/m, P < 0.05), whereas carotid intima-media thickness was superimposable. AnxA5 correlates with PWV (r = 0.13, P < 0.05) and DBP (r = 0.15, P < 0.01), whereas it has never been found as a significant independent predictor of TOD in linear regression analysis. CONCLUSION: Our data have shown that AnxA5 levels are increased in treated hypertension patients. In this condition, it is probably released in the plasma as a defensive mechanism through its anti-inflammatory and anticoagulants effects. We found a significant association with arterial stiffness, but AnxA5 was not found to be a significant predictor of TOD.
