RESUMO

AIMS: Fractional flow reserve (FFR) has never been investigated in patients with reduced ejection fraction and associated coronary artery disease (CAD). We evaluated the impact of FFR on the management strategies of these patients and related outcomes. METHODS AND RESULTS: From 2002 to 2010, all consecutive patients with left ventricular ejection fraction (LVEF) ≤50% undergoing coronary angiography with ≥1 intermediate coronary stenosis [diameter stenosis (DS)% 50-70%] treated based on angiography (Angiography-guided group) or according to FFR (FFR-guided group) were screened for inclusion. In the FFR-guided group, 433 patients were matched with 866 contemporary patients of the Angiography-guided group. For outcome comparison, 617 control patients with LVEF >50% were included. After FFR, stenotic vessels per patient were significantly downgraded compared with the Angiography-guided group (1.43 ± 0.98 vs. 1.97 ± 0.84; P < 0.001). This was associated with lower revascularization rate (52% vs. 62%; P < 0.001) in the FFR-guided vs. the Angiography-guided group. All-cause death at 5 years of follow-up was significantly lower in the FFR-guided as compared with Angiography-guided group [22% vs. 31%. HR (95% CI) 0.64 (0.51-0.81); P < 0.001]. Similarly, rate of major adverse cardiovascular and cerebrovascular events (MACCE: composite of all-cause death, myocardial infarction, revascularization, and stroke) was significantly lower in the FFR-guided group [40% vs. 46% in the Angiography-guided group. HR (95% CI) 0.81 (0.67-0.97); P = 0.019]. Higher rates of death and MACCE were observed in patients with reduced LVEF compared with the control cohort. CONCLUSIONS: In patients with reduced LVEF and CAD, FFR-guided revascularization was associated with lower rates of death and MACCE at 5 years as compared with the Angiography-guided strategy. This beneficial impact was observed in parallel with less coronary artery bypass grafting and more patients deferred to percutaneous coronary intervention or medical therapy.

RESUMO

Ischemic stroke represents one of the most important health problems in industrialized countries, both for epidemiological and socio-economic impact. The presence of thrombi in the aorta is rare and its treatment has not been uniquely defined. Here we report the case of an 82-years-old man with aortic thrombosis and acute ischemic stroke.

RESUMO

Objectives: Increased arterial stiffness is associated with advanced arteriosclerosis, abnormal left ventricular (LV) geometry and function. Whether increased arterial stiffness is associated with incident cardiovascular (CV) event (MACE), independent of other markers of target organ damage needs to be clarified. Methods: We selected hypertensive participants of the Campania Salute Network free of prevalent CV disease, with available echocardiogram and carotid ultrasound, ejection fraction ≥50%, and ≤ stage III Chronic Kidney Disease (n = 6907). Median follow-up was 63 months. End-point was incident MACE (fatal and non-fatal stroke and myocardial infarction, sudden cardiac death, carotid stenting and heart failure requiring hospitalization). Arterial stiffness was assessed from ratio of brachial pulse pressure/stroke index (i.e. normalized for body height in meter to 2.04 power) (PP/SVi). High PP/SVi (n = 980) was defined as >95th sex-specific percentile of the normal distribution from a reference normal population (>2.63/>2.82 mmHg/ml in men and women, respectively). Results: Patients with high PP/SVi were more likely to be women, older, diabetic, with higher systolic blood pressure (BP) and heart rate, more LV concentric geometry, left atrial dilatation and more carotid plaque (all p < .01). At given increase in SVi, patients with high PP/SVi exhibited two-fold increase in PP compared to normal PP/SVi. In Cox regression, patients with high PP/SVi had 63% increased hazard of MACE [95% CI (1.02-2.59) p = .04], independently of significant effect of older age, male sex, carotid plaque and less frequent anti-RAS therapy. Conclusions: In treated hypertensive patients, high PP/SVi predicted increased rate of MACE, independent of common confounders.

RESUMO

Background: Hypertension is a leading cause of chronic kidney disease (CKD) and a decrease in glomerular filtration rate (GFR) is associated with a higher prevalence of hypertension and an increased proportion of suboptimal blood pressure (BP) control. Methods: To investigate characteristics associated with GFR decline, we selected 4539 hypertensive patients from the Campania Salute Network (mean age 53 ± 11 years) with at least 3 years of follow-up (FU) and no more than Stage III CKD. GFR was calculated at baseline and at the last available visit using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. GFR decline was defined as a ≥30% decrease from initial GFR for patients in Stage III CKD or by a composite ≥30% decrease from baseline and a final value of <60 for those < with Stage III or higher CKD. Results: At a mean FU of 7.5 years, 432 patients (10%) presented with GFR decline. Those patients were older, more likely to be diabetic, with lower GFR and ejection fraction, higher systolic and lower diastolic BP and higher left ventricular (LV) mass and relative wall thickness at baseline; during FU, patients with GFR decline exhibited higher systolic BP, took more drugs and developed more atrial fibrillation (all P < 0.02). The probability of GFR decline was independently associated with older age, prevalent diabetes, baseline lower GFR, higher systolic BP during FU, FU duration, increased LV mass and incident AF with no impact from antihypertensive and antiplatelet medications. Conclusions: During antihypertensive therapy, kidney function declines in patients with initially lower GFR, increased LV mass and suboptimal BP control during FU.

RESUMO

PURPOSE: Atherosclerosis is a systemic disease and coronary artery disease is frequently associated with peripheral artery disease. As aortic and mitral valvular calcification (VC) share some etiopathogenetic mechanisms with atherosclerosis, we analyzed the risk profile and the echocardiographic characteristics of patients admitted for first acute coronary syndrome (ACS) to investigate whether the presence of VC could be a marker of asymptomatic hemodynamically significant peripheral atherosclerosis. METHODS: A total of 151 patients admitted for ACS without previous history of cardiovascular disease were consecutively enrolled. The presence of VC was identified by echocardiography; a carotid stenosis ≥50% by ultrasound identified carotid artery disease (CarAD); an ankle-brachial index ≤0.9 or ≥1.4 identified lower extremity artery disease (LEAD). Significant peripheral atherosclerosis was defined by the presence of CarAD and/or LEAD. RESULTS: Peripheral atherosclerosis was diagnosed in 82 (54.3%) patients; isolated CarAD in 24, isolated LEAD in 20, both diseases in 38 patients. VC was present in 103 (68.2%) patients. By multivariate analysis, age (OR = 1.059, 95% CI 1.007-1.113, P = 0.025), diabetes mellitus (OR = 5.068, 95% CI 1.480-17.351, P = 0.010), VC (OR = 7.422, 95% CI 2.421-22.880, P < 0.001), and multivessel CAD (OR = 3.317, 95% CI 1.281-8.586, P = 0.013) were the only independent predictors of having peripheral atherosclerosis. C-statistic for VC was not inferior to that obtained by age (0.728, 95% CI 0.649-0.797 vs. 0.800, 95% CI 0.727-0.861, P = 0.101) and to that obtained by the combination of multivessel CAD with diabetes (0.750; 95% CI 0.673-0.817, P = 0.635), and, furthermore, it was higher than that obtained by diabetes alone (0.620, 95% CI 0.538-0.698, P = 0.036). CONCLUSION: Ruling out the presence of significant peripheral atherosclerosis should be routinely considered in patients with ACS showing VC at echocardiography.

RESUMO

INTRODUCTION: No data are available on the diagnostic algorithms recommended by guidelines for the assessment of diastolic dysfunction (DD) in patients with arterial hypertension. AIM: To fill this gap, we evaluated diastolic function in hypertensive patients with and without LVH matched with healthy subjects by applying 2016 American Society of Echocardiography-European Association of Cardiovascular Imaging Guidelines for the evaluation of LV diastolic function. METHODS: 717 healthy and hypertensives with normal LV ejection fraction and with and without LV hypertrophy (LVH), matched 1:1:1 from two prospective registries, represented the study population. RESULTS: By applying algorithm A, indeterminate pattern was found in 0.4% of healthy, in 6.3% of hypertensives without LVH, and in 21% with LVH (overall p < 0.05 vs. healthy). DD was absent in healthy, however present in 2 and 8% of hypertensives without and with LVH (p = 0.06 and p = 0.001 vs. healthy, respectively). By applying algorithm B, no cases of indeterminate pattern were found. DD was observed in 2.9% of healthy, 7 and 10.5% of hypertensives without and with LVH (p < 0.05 vs. healthy). CONCLUSIONS: The use of algorithm A should be limited only to truly normal subjects, whereas algorithm B should be applied to all patients with hypertension, even without comorbidities and irrespective of LVH.

RESUMO

BACKGROUND AND AIM: Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM) with significant effects on outcome. We aim to compare the left atrial (LA) diameter measurement with HCM-AF Score in predicting atrial fibrillation (AF) development in HCM. METHODS: From the regional cohort of the Campania Region, Italy, 519 HCM patients (38% women, age45 ± 17 years) without history of AF, were enrolled in the study. The primary clinical endpoint was the development of AF, defined as at least 1 episode documented by ECG. RESULTS: During the follow-up (mean 8 ± 6, IQ range 2.5-11.2 years), 99 patients (19%) developed AF. Patients who developed AF were more symptomatic, had higher prevalence of ICD implantation, had larger LA diameter, greater left ventricular (LV) maximal wall thickness and LV outflow tract obstruction (p < 0.01). Both LA diameter and HCM-AF score were higher in patients who developed AF versus those who did not (LA diameter 49 ± 7 versus 43 ± 6 mm; HCM-AF score 22 ± 4 versus 19 ± 4; p < 0.0001); however, ROC curve analysis demonstrated that LA diameter had a significant greater area under the curve than HCM-AF Score (p < 0.0001). At 5 years follow-up, a LA diameter > 46 mm, showed a similar accuracy in predicting AF development of HCM-AF score ≥ 22, which identifies patients at high risk to develop AF. CONCLUSION: Our analysis shows that LA diameter, a worldwide and simple echocardiographic measure, is capable alone to predict AF development in HCM patients.

RESUMO

Hypertrophic cardiomyopathy (HCM) is mainly caused by sarcomeric mutations which may affect myocardial mechano-energetic efficiency (MEE). We investigated the effects of sarcomeric mutations on MEE. A non-invasive pressure/volume (P/V) analysis was performed. We included 49 genetically screened HCM patients. MEEi was calculated as the ratio between stroke volume and heart rate normalized by LV mass. Fifty-seven percent (57%) HCM patients carried a sarcomeric mutation. Patients with and without sarcomeric mutations had similar LV ejection fraction, heart rate, LV mass, and LV outflow gradient. Younger age at diagnosis, family history of HCM, and lower MEEi were associated with presence of sarcomeric mutation (p = 0.017; p = 0.001 and p = 0.0001, respectively). Lower MEEi in HCM with sarcomeric mutation is not related to significant differences on filling pressure as shown on P/V analysis. Sarcomeric mutations determine a reduction of the LV pump performance as estimated by MEEi in HCM. Lower MEEi may predict a positive genetic analysis.

RESUMO

Aortic stenosis (AS) is a valvular heart disease that significantly contributes to cardiovascular morbidity and mortality worldwide. The condition is characterized by calcification and thickening of the aortic valve leaflets, resulting in a narrowed orifice and increased pressure gradient across the valve. AS typically progresses from a subclinical phase known as aortic sclerosis, where valve calcification occurs without a transvalvular gradient, to a more advanced stage marked by a triad of symptoms: heart failure, syncope, and angina. Echocardiography plays a crucial role in the diagnosis and evaluation of AS, serving as the primary non-invasive imaging modality. However, to minimize misdiagnoses, it is crucial to adhere to a standardized protocol for acquiring echocardiographic images. This is because, despite continuous advances in echocardiographic technology, diagnostic errors still occur during the evaluation of AS, particularly in classifying its severity and hemodynamic characteristics. This review focuses on providing guidance for the imager during the echocardiographic assessment of AS. Firstly, the review will report on how the echo machine should be set to improve image quality and reduce noise and artifacts. Thereafter, the review will report specific emphasis on accurate measurements of left ventricular outflow tract diameter, aortic valve morphology and movement, as well as aortic and left ventricular outflow tract velocities. By considering these key factors, clinicians can ensure consistency and accuracy in the evaluation of AS using echocardiography.

RESUMO

Hypertrophic cardiomyopathy (HCM) is a genetic disease with heterogeneous clinical presentation and prognosis. Within the broad phenotypic expression of HCM, there is a subgroup of patients with a left ventricular (LV) apical aneurysm, which has an estimated prevalence between 2% and 5%. LV apical aneurysm is characterized by an area of apical dyskinesis or akinesis, often associated with regional scarring. To date, the most accepted pathomechanism of this complication is, in absence of coronary artery disease, the high systolic intra-aneurysmal pressure, which, combined with impaired diastolic perfusion from lower stroke volume, results in supply-demand ischemia and myocardial injury. Apical aneurysm is increasingly recognized as a poor prognostic marker; however, the efficacy of prophylactic anticoagulation and/or intracardiac cardioverted defibrillator (ICD) in improving morbidity and mortality is not yet clearly demonstrated. This review aims to elucidate the mechanism, diagnosis and clinical implication of LV aneurysm in patients with HCM.

RESUMO

Aortic stenosis (AS) can often coexist with other valvular diseases or be combined with aortic regurgitation (AR), leading to unique pathophysiological conditions. The combination of affected valves can vary widely, resulting in a lack of standardized diagnostic or therapeutic approaches. Echocardiography is crucial in assessing patients with valvular heart disease (VHD), but careful consideration of the hemodynamic interactions between combined valvular defects is necessary. This is important as it may affect the reliability of commonly used echocardiographic parameters, making the diagnosis challenging. Therefore, a multimodality imaging approach, including computed tomography or cardiac magnetic resonance, is often not just beneficial but crucial. It represents the future of diagnostics in this intricate field due to its unprecedented capacity to quantify and comprehend valvular pathology. The absence of definitive data and guidelines for the therapeutic management of AS in the context of multiple valve lesions makes this condition particularly challenging. As a result, an individualized, case-by-case approach is necessary, guided primarily by the recommendations for the predominant valve lesion. This review aims to summarize the pathophysiology of AS in the context of multiple and mixed valve disease, with a focus on the hemodynamic implications, diagnostic challenges, and therapeutic options.

RESUMO

Cardiac surgery is necessary in almost 50% of patients with endocarditis. Early surgery, i.e., the surgery performed during the first hospitalization, is required in the following cases: heart failure secondary to valve regurgitation; S. aureus, fungal organism, or other highly resistant organism infection; heart block, annular or aortic abscess, or destructive penetrating lesions; evidence of persistent infection as manifested by persistent bacteremia or fevers lasting >5 days after onset of appropriate antimicrobial therapy. A 62-year-old man developed a fever (38 °C) 3 days after a transaortic electrophysiological study; blood cultures were positive for S. aureus, and were sensitive to vancomycin and ceftaroline. Antibiotic therapy was started, controlling the fever and the patient's infective and inflammatory profiles well; however, 3 days later, acute aortic regurgitation developed. At transesophageal echocardiography (TEE), a rare condition was revealed-vegetation was attached to the aortic wall, impeding correct aortic valve closure. Cardiac operation was carried out and the time for surgery was discussed; based on the patient's clinically stable condition, and on the infection, which was controlled well by antibiotics therapy, surgery was not performed in emergency circumstance (within 24-48 h)-rather, it was programmed during the hospitalization. A TEE surveillance was initiated, and after 7 days, TEE revealed a new picture, with images of an aortic abscess with small perforation in the right atrium, requiring emergency surgery, carried out 20 h later. In our case, the rapid evolution of the vegetation attached to the aortic wall suggested the following: (1) that the time for the surgery cannot be guided only by clinical procedure but must also be guided by imaging pictures; (2) that strictly TEE surveillance is mandatory in patients with aortic endocarditis not initially referred for emergency surgery.

RESUMO

Background: The influence of age and gender on strain-imaging-derived myocardial work (MW) was recently investigated in healthy subjects. No information is available on the impact of heart rate (HR) on MW. Methods: 177 healthy subjects (47% men, mean age 42 years) underwent an echo-Doppler exam, including quantification of global longitudinal strain (GLS). Cuff blood pressure was used as a surrogate of left ventricular peak pressure to estimate global work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE). Statistical analyses were performed according to age and HR tertiles. Results: GWW was higher in the third HR tertile, i.e., ≥74 bpm (74.7 ± 33.6 mmHg %) than in the first HR tertile (<66 bpm) (61.0 ± 32.5 mmHg %) (p < 0.02). In the pooled population, by adjusting for systolic blood pressure, GLS, E/e' ratio and left atrial volume index, age was independently associated with GCW (ß = 0.748) and GWI (ß = 0.685) (both p < 0.0001) and HR with GWW (ß = 0.212, p = 0.006) and GWE (ß = −0.204, p = 0.007). Conclusions: In healthy subjects age shows a mild influence on GCW. HR exerts an independent negative impact on GWW and GWE: the higher HR the greater wasted work and lower myocardial efficiency.

RESUMO

Increased intima-media thickness (IMT) of common carotid artery (CA) is considered the hallmark of vascular hypertension-mediated target organ damage, even if vessel remodeling due to mechanical stress may also induce changes in diameter. We developed a method computing both diameter and IMT of CA, to assess correlates and prognostic impact of carotid cross-sectional area (CCSA) in a large registry of treated hypertensive patients. We selected 6300 hypertensive patients of the Campania Salute Network registry free of overt cardiovascular (CV) disease and with available CA ultrasound (54 ± 11 years; 57% male). CCSA was computed as:[Formula: see text]CCSA was considered high if >90th percentile of the sex-specific distribution (>48 mm2 in men and >41 mm2 in women). Patients with high CCSA were male, with older age, higher pulse pressure (PP), more prevalent obese and diabetic, with higher total and LDL cholesterol (p < 0.01 for all). During a median follow-up of 60 months (IQR 19-87), 206 incident composite major and minor CV events occurred. In Cox regression analysis high CCSA was associated with more than 100% increased risk of incident CV events ((HR 2.11, 95%CI 1.46-3.1, p < 0.0001), independently of the effect of older age, male sex, PP > 60 mmHg, presence of left ventricular hypertrophy (LVH), carotid plaque (CP), and less anti-RAS therapy (p < 0.05 for all). In treated hypertensive patients, increased CCSA is associated with worse metabolic and lipid profile and predict incident CV events, independently of high PP, presence of LVH and CP.

RESUMO

BACKGROUND: Determinants of changes of aortic root dimension over time are not well defined. DESIGN: We investigated whether specific phenotype and treatment exist predicting changes in aortic root dimension in hypertensive patients from the Campania Salute Network. METHODS: N = 4856 participants (age 53 ± 11 years, 44% women) were included. At first and last available echocardiograms, we measured aortic root and a z-score of aortic root (AOz) was generated as the difference between measured and predicted aortic root, derived from a healthy reference population. Aortic root dilatation (ARD) was defined as AOz >75th percentile of distribution. RESULTS: At baseline, 3642 patients (75%) exhibited normal aortic root, and 1214 (25%) ARD. After a follow-up of 6.1 years (interquartile range 3.0-8.8 years), 366 (11%) patients with initial normal aortic root exhibited ARD, whereas 457(38%) with initial ARD exhibited normal aortic root. At multivariate analysis patients with incident ARD were most likely to be women, obese, with left ventricular hypertrophy, lower systolic but higher diastolic blood pressure and stroke volume index at baseline, and higher average value of diastolic blood pressure during follow-up (p < 0.05); whereas patients normalizing their ARD were non-obese women with lower baseline systolic blood pressure, stroke volume index, average diastolic blood pressure during follow-up and longer follow-up time (p < 0.05). Anti-renin-angiotensin system (anti-RAS) was associated with 45% greater probability to normalize aortic root dimension. CONCLUSIONS: Volume (stroke volume index) and pressure loads (diastolic blood pressure) influence aortic root dimension over time. Aortic root normalization, reflecting a more favourable haemodynamic load, is predictable in non-obese women with lower diastolic blood pressure, taking more anti-RAS therapy. This suggest that sex elicits a different response in aortic walls to pathological stimuli.

RESUMO

BACKGROUND: Exaggerated variability of blood pressure (BP) poses additional stress on cardiovascular system independent of BP average value, increasing risk of target organ damage (HMOD) and cardiovascular events. We assessed the impact of visit-to-visit variability (VVV) of BP on development of cardiovascular events and HMOD. METHODS: Standard deviation (SD) and coefficient of variability of mean SBP and DBP were calculated in 3555 patients from the Campania Salute Network registry, with available echocardiogram and more than six visits during follow-up. Values from the first visit were excluded. The impact of VVV of BP on cardiovascular events, and mediation of HMOD were assessed at final visit. RESULTS: Mean number of visits was 11 ±â€Š6 with mean interval between visits of 9.1 ±â€Š3.7 months. Mean visit-to-visit SD during follow-up was 13 ±â€Š5 for systolic and 8 ±â€Š3 mmHg for DBP; coefficients of variability were 9.7 ±â€Š3.5 and of 9.6 ±â€Š3.2, respectively. In multivariable analysis, left ventricular mass at follow-up was correlated with systolic VVV of BP independently of significant effect of age, BMI, mean SBP during follow-up and initial left ventricular mass. Follow-up GFR was inversely associated with systolic and diastolic VVV, independently of significant effect of age, mean glucose and SBP during follow-up, and initial GFR. In Cox regression, high VVV of BP was also associated with increased risk of cardiovascular events (hazard ratio 1.49, 95% confidence interval 1.08-2.06, P = 0.015), independently of significant effect of HMOD. CONCLUSION: VVV is associated with prevalent HMOD and development of cardiovascular events, independently of mean BP value during follow-up and HMOD.

RESUMO

BACKGROUND: Sympathetic dysfunction can be evaluated by heart rate reserve (HRR) with exercise test. OBJECTIVES: To determine the value of HRR in predicting outcome of patients with hypertrophic cardiomyopathy (HCM). METHODS: We enrolled 917 HCM patients (age = 49 ± 15 years, 516 men) assessed with exercise stress echocardiography (ESE) in 11 centres. ESE modality was semi-supine bicycle in 51 patients (6%), upright bicycle in 476 (52%), and treadmill in 390 (42%). During ESE, we assessed left ventricular outflow tract obstruction (LVOTO), stress-induced new regional wall motion abnormalities (RWMA), and HRR (peak/rest heart rate, HR). By selection, all patients completed the follow-up. Mortality was the predetermined outcome measure Results: During ESE, RWMA occurred in 22 patients (2.4%) and LVOTO (≥50 mmHg) in 281 (30.4%). HRR was 1.90 ± 0.40 (lowest quartile ≤ 1.61, highest quartile > 2.13). Higher resting heart rate (odds ratio 1.027, 95% CI: 1.018-1.036, p < 0.001), older age (odds ratio 1.021, 95% CI: 1.009-1.033, p < 0.001), lower exercise tolerance (mets, odds ratio 0.761, 95% CI: 0.708-0.817, p < 0.001) and resting LVOTO (odds ratio 1.504, 95% CI: 1.043-2.170, p = 0.029) predicted a reduced HRR. During a median follow-up of 89 months (interquartile range: 36-145 months), 90 all-cause deaths occurred. At multivariable analysis, lowest quartile HRR (Hazard ratio 2.354, 95% CI 1.116-4.968 p = 0.025) and RWMA (Hazard ratio 3.279, 95% CI 1.441-7.461 p = 0.004) independently predicted death, in addition to age (Hazard ratio 1.064, 95% CI 1.043-1.085 p < 0.001) and maximal wall thickness (Hazard ratio 1.081, 95% CI 1.037-1.128, p < 0.001). CONCLUSIONS: A blunted HRR during ESE predicts survival independently of RWMA in HCM patients.

RESUMO

We aim to validate echocardiographic left ventricular (LV) mass (echoLVM) in sixty-one patients with hypertrophic cardiomyopathy (HCM), using cardiac magnetic resonance measures (cmrLVM) as gold standard. cmrLVM was calculated using LV short-axis images, from base to apex, whereas echoLVM by LV epicardial minus LV endocardial volumes in 4 and 2 chamber views, using Simpson disk summation; trabeculae and papillary muscle were excluded in both cmrLVM and echoLVM. cmrLVM and echoLVM were not different by paired t test (145 ± 66 vs 147 ± 61; p = 0.240), and their correlation was good (r = 0.977; p < 0.0001). Intraclass correlation demonstrated reliability of echoLVM with cmrLVM (ρ = 0.987; Cls = 0.978-0.992; p < 0.0001). LV end-diastolic volume was higher by CMR than that by echo (137 ± 33 vs 85 ± 28 mL, p < 0.0001), resulting in a lower mass/volume ratio (1.1 ± 0.4 vs 1.8 ± 0.8, p < 0.0001). EchoLVM may be determined in patients with HCM. However, mass/volume ratio is higher by echocardiography than that by CMR.

RESUMO

INTRODUCTION: The ESC-2018 guidelines suggest the use of Unattended automated office blood pressure (UAOBP) to avoid or at least reduce the white coat effect, even if do not support its use as preferred method. AIM: To assess the pressure difference between UAOBP and Attended office blood pressure (AOBP) and to evaluate their correlations with target organ damage in hypertensive patients. METHODS: UAOBP and AOBP were taken in a cohort of 48 outpatients. The pressure difference between the 2 methods and their correlation with anthropometric and cardiac parameters were analyzed. RESULTS: Unattended systolic and diastolic BP were lower than Attended systolic and diastolic BP (135 ± 17 mmHg vs 139 ± 21 mmHg and 79 ± 10 mmHg vs 82 ± 10 mmg). ΔDBP was significantly directly correlated with female sex (r = 0.347, p = 0.016) and it was lower in men compared to women (0.11 ± 8.9 mmHg vs 6.07 ± 7.42 mmHg, p = 0.016). Correlation coefficients for LVMi and RWT for attended and unattended BP were not statistically different (for LVMi r = 0.286 vs r = 0.381, p = 0.61, for RWT r = 0.413 vs r = 0.363, p = 0.78). The relationship between attended and unattended BP was described by the following equation: y = - 4.68 + 1.06*x; where Y is the attended systolic BP and X is the unattended systolic BP; in accordance with this equation, an unattended systolic BP of 140 mmHg corresponds to an attended systolic BP of 143.7 mmHg. CONCLUSIONS: UAOBP provides significantly lower values than AOBP. The difference in BP values between the two methods is much lower than the one obtained in most clinical studies.
