RESUMO

BACKGROUND AND AIM: Recently, the European Society of Cardiology task force released a Consensus document (ESC-CD) on pediatric hypertension (HTN) supporting the use of normative tables (age range 6-16 years) for the diagnosis of HTN, while the Hypertension Canada Guidelines (HTN-CGs) proposed static cutoffs. We aimed to assess the prevalence of HTN by ESC-CD or HTN-CGs and their association with glomerular function and left ventricular (LV) geometry in youths with overweight/obesity (OW/OB). METHODS AND RESULTS: Data of 3446 youths were analyzed. HTN by was defined using normative tables (ESC-CD) or static cutoffs of BP ≥ 120/80 in children (age <12 years) and ≥130/85 mmHg in adolescents (age ≥12 years) (HTN-CGs). Mildly reduced glomerular filtration rate was defined by GFR <90 ≥ 60 mL/min/1.73 m2. Concentric LV hypertrophy (cLVH) was assessed in 500 youths and defined by LVH and high relative wall thickness as proposed by ESC-CD. Prevalence of HTN was 27.9% by ESC-CD and 22.7% by HTN-CGs. The association with mildly reduced glomerular filtration rate was significant only in hypertensive adolescents classified by HTN-CGs [Odds Ratio (OR), 95%Cl] 2.16 (1.44-3.24), whereas the association with cLVH was significant using both criteria: children OR 2.18 (1.29-3.67) by ESC-CD and 2.27 (1.32-3.89) by HTN-CGs; adolescents OR 2.62 (1.17-5.84) by ESC-CD and 2.83 (1.14-7.02) by HTN-CGs. CONCLUSION: Although static cutoffs may represent a simplification for HTN identification, tables by ESC-CD detect a higher number of hypertensive youths before a clear appearance of glomerular impairment, which offers advantages in terms of primary cardiovascular prevention.

RESUMO

Definition and management of arterial hypertension in children and adolescents are uncertain, due to different positions of current guidelines. The European Society of Cardiology task-force, constituted by Associations and Councils with interest in arterial hypertension, has reviewed current literature and evidence, to produce a Consensus Document focused on aspects of hypertension in the age range of 6-16 years, including definition, methods of measurement of blood pressure, clinical evaluation, assessment of hypertension-mediated target organ damage, evaluation of possible vascular, renal and hormonal causes, assessment and management of concomitant risk factors with specific attention for obesity, and anti-hypertensive strategies, especially focused on life-style modifications. The Consensus Panel also suggests aspects that should be studied with high priority, including generation of multi-ethnic sex, age and height specific European normative tables, implementation of randomized clinical trials on different diagnostic and therapeutic aspects, and long-term cohort studies to link with adult cardiovascular risk. Finally, suggestions for the successful implementation of the contents of the present Consensus document are also given.

RESUMO

There is strong evidence that sex chromosomes and sex hormones influence blood pressure (BP) regulation, distribution of cardiovascular (CV) risk factors and co-morbidities differentially in females and males with essential arterial hypertension. The risk for CV disease increases at a lower BP level in females than in males, suggesting that sex-specific thresholds for diagnosis of hypertension may be reasonable. However, due to paucity of data, in particularly from specifically designed clinical trials, it is not yet known whether hypertension should be differently managed in females and males, including treatment goals and choice and dosages of antihypertensive drugs. Accordingly, this consensus document was conceived to provide a comprehensive overview of current knowledge on sex differences in essential hypertension including BP development over the life course, development of hypertension, pathophysiologic mechanisms regulating BP, interaction of BP with CV risk factors and co-morbidities, hypertension-mediated organ damage in the heart and the arteries, impact on incident CV disease, and differences in the effect of antihypertensive treatment. The consensus document also highlights areas where focused research is needed to advance sex-specific prevention and management of hypertension.

RESUMO

Drying of wet granules in a fluidized bed dryer is an important part of the pharmaceutical tablet manufacturing process. Complicated gas-solid flow patterns appear in the fluidized bed dryer, and interphase momentum, heat, and mass transfer happen during the drying process. A coupled computational fluid dynamics (CFD)-discrete element method (DEM)-based approach was used to model the drying process of pharmaceutical wet granules in a fluidized bed dryer. The evaporation of water from the surfaces of the particles and the cohesion force between the particles due to the formation of liquid bridges between the particles were also considered in this model. The model was validated by comparing the model predictions with the experimental data available from the literatures. The validated model was used to investigate the drying kinetics of the wet granules in the fluidized bed dryer. The results from numerical simulations showed that the dynamics and rate of increase of temperature of wet particles were considerably different from those of dry particles. Finally, the model was used to investigate the effects of inlet air velocity and inlet air temperature on the drying process. The model predicted increase in drying rate with the increase of inlet air velocity and inlet air temperature. This model can help not only to understand the multiphase multicomponent flow in fluidized bed dryer but also to optimize the drying process in the fluidized bed dryer.

RESUMO

OBJECTIVES: Radiomic involves testing the associations of a large number of quantitative imaging features with clinical characteristics. Our aim was to extract a radiomic signature from axial T2-weighted (T2-W) magnetic resonance imaging (MRI) of the whole prostate able to predict oncological and radiological scores in prostate cancer (PCa). METHODS: This study included 65 patients with localized PCa treated with radiotherapy (RT) between 2014 and 2018. For each patient, the T2-W MRI images were normalized with the histogram intensity scale standardization method. Features were extracted with the IBEX software. The association of each radiomic feature with risk class, T-stage, Gleason score (GS), extracapsular extension (ECE) score, and Prostate Imaging Reporting and Data System (PI-RADS v2) score was assessed by univariate and multivariate analysis. RESULTS: Forty-nine out of 65 patients were eligible. Among the 1702 features extracted, 3 to 6 features with the highest predictive power were selected for each outcome. This analysis showed that texture features were the most predictive for GS, PI-RADS v2 score, and risk class; intensity features were highly associated with T-stage, ECE score, and risk class, with areas under the receiver operating characteristic curve (ROC AUC) ranging from 0.74 to 0.94. CONCLUSIONS: MRI-based radiomics is a promising tool for prediction of PCa characteristics. Although a significant association was found between the selected features and all the mentioned clinical/radiological scores, further validations on larger cohorts are needed before these findings can be applied in the clinical practice. KEY POINTS: • A radiomic model was used to classify PCa aggressiveness. • Radiomic analysis was performed on T2-W magnetic resonance images of the whole prostate gland. • The most predictive features belong to the texture (57%) and intensity (43%) domains.

RESUMO

Based on literature, intensity-modulated radiation therapy (IMRT) provides less related toxicity compared with conventional 2D/3D-RT with no impact on oncological outcomes for oropharyngeal cancer. The aim of this systematic review and meta-analysis is to assess whether IMRT might provide similar clinical outcomes with reduced related toxicity in comparison with conventional 2D/3D RT in patients treated for clinically advanced oropharyngeal cancer (OPC). Inclusion criteria for paper selection included: squamous OPC patients, treatment performed by concomitant CRT or RT alone, four treatment performed for curative intent, and presence of clinical outcome of interest, namely, overall survival (OS) and disease-free survival (DFS) and full paper available in English. Acute and late toxicities were retrieved together with OS and DFS. Crude relative risk estimates of relapse and death comparing 2D/3D-RT versus IMRT were calculated from tabular data, extracting events at 2-3 years of follow-up. Eight studies were selected. Six of them were included in the meta-analysis considering summary relative risk. Considering both acute and late toxicities, the considered studies evidenced advantages for IMRT populations, with the 2D/3D-RT population showing higher frequencies than the IMRT one. No statistical difference between IMRT and 2D/3D-RT in terms of death (SRR = 0.93, 95% CI: 0.83-1.04 with no heterogeneity I2  = 0%) and relapse (SRR = 0.92, 95% CI: 0.83-1.03, with no heterogeneity I2  = 0%) was found. Results of our study suggest the improvement in the therapeutic index with IMRT with evidenced reduced toxicity without any worsening in clinical outcome when compared to 2D/3DCRT.

RESUMO

BACKGROUND AND AIM: To compare cardiometabolic risk profile and preclinical signs of target organ damage in youth with normal and elevated blood pressure (BP), according to the American Academy of Pediatrics (AAP) guidelines. METHODS AND RESULTS: This cross-sectional multicenter study included 2739 youth (5-17 year-old; 170 normal-weight, 610 overweight and 1959 with obesity) defined non hypertensive by the AAP guidelines. Anthropometric, biochemical and liver ultrasound data were available in the whole population; carotid artery ultrasound and echocardiographic assessments were available respectively in 427 and 264 youth. Elevated BP was defined as BP ≥ 90th to <95th percentile for age, gender and height in children or BP ≥ 120/80 to <130/80 in adolescents. The overall prevalence of elevated BP was 18.3%, and significantly increased from normal-weight to obese youth. Young people with elevated BP showed higher levels of body mass index (BMI), insulin resistance and a higher prevalence of liver steatosis (45% vs 36%, p < 0.0001) than normotensive youth, whilst they did not differ for the other cardiometabolic risk factors, neither for carotid intima media thickness or left ventricular mass. Compared with normotensive youth, individuals with elevated BP had an odds ratio (95%Cl) of 3.60 (2.00-6.46) for overweight/obesity, 1.46 (1.19-1.78) for insulin-resistance and 1.45 (1.19-1.77) for liver steatosis, controlling for centers, age and prepubertal stage. The odds for insulin resistance and liver steatosis persisted elevated after correction for BMI-SDS. CONCLUSION: Compared to normotensive youth, elevated BP is associated with increased BMI, insulin resistance and liver steatosis, without significant target organ damage.

RESUMO

AIM: To evaluate the role of baseline neutrophil-to-lymphocyte ratio (NLR) as prognostic marker in squamous cell carcinoma of the oropharynx (OPC) treated with definitive chemoradiotherapy (CRT) in the era of HPV status. PATIENTS AND METHODS: A retrospective analysis of 125 patients (pts) affected with locally advanced OPC was performed. Inclusion criteria were age >18 years, stage III or IV (TNM 7th ed.) and definitive CRT. Haematological marker for their independent role as prognostic biomarkers for progression-free survival (PFS) and overall survival (OS). Logistic models were used to assess the association with downstage in TNM 8th ed. RESULTS: Seventy-seven (61.6%) pts had HPV/p16 + related OPC. Therapeutic choice consisted in sequential and concurrent CRT. Median follow-up was 50 months. A value of NLR ≥3 was associated with poorer OS. Two-year OS was 91% and 81% in pts with NLR <3 and ≥3, respectively. CONCLUSION: A baseline NLR ≥ 3 at treatment initiation represented a negative prognostic marker for OPC treated with definitive CRT. These results are in line with literature data, and prognostic value of NLR has been confirmed restaging our cohort with new TNM staging (8th ed.). Therefore, NLR could be considered a valuable biomarker for risk stratification in pts with OPC.

RESUMO

BACKGROUND: Myocardial energetic efficiency (MEE), is a strong predictor of CV events in hypertensive patient and is reduced in patients with diabetes and metabolic syndrome. We hypothesized that severity of insulin resistance (by HOMA-IR) negatively influences MEE in participants from the Strong Heart Study (SHS). METHODS: We selected non-diabetic participants (n = 3128, 47 ± 17 years, 1807 women, 1447 obese, 870 hypertensive) free of cardiovascular (CV) disease, by merging two cohorts (Strong Heart Study and Strong Heart Family Study, age range 18-93). MEE was estimated as stroke work (SW = systolic blood pressure [SBP] × stroke volume [SV])/"double product" of SBP × heart rate (HR), as an estimate of O2 consumption, which can be simplified as SV/HR ratio and expressed in ml/sec. Due to the strong correlation, MEE was normalized by left ventricular (LV) mass (MEEi). RESULTS: Linear trend analyses showed that with increasing quartiles of HOMA-IR patients were older, more likely to be women, obese and hypertensive, with a trend toward a worse lipid profile (all p for trend < 0.001), progressive increase in LV mass index, stroke index and cardiac index and decline of wall mechanics (all p < 0.0001). In multivariable regression, after adjusting for confounders, and including a kinship coefficient to correct for relatedness, MEEi was negatively associated with HOMA-IR, independently of significant associations with age, sex, blood pressure, lipid profile and central obesity (all p < 0.0001). CONCLUSIONS: Severity of insulin resistance has significant and independent negative impact on myocardial mechano-energetic efficiency in nondiabetic individual from a population study of American Indians. Trial registration number NCT00005134, Name of registry: Strong Heart Study, URL of registry: https://clinicaltrials.gov/ct2/show/NCT00005134 , Date of registration: May 25, 2000, Date of enrolment of the first participant to the trial: September 1988.

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

These practice guidelines on the management of arterial hypertension are a concise summary of the more extensive ones prepared by the Task Force jointly appointed by the European Society of Hypertension and the European Society of Cardiology. These guidelines have been prepared on the basis of the best available evidence on all issues deserving recommendations; their role must be educational and not prescriptive or coercive for the management of individual subjects who may differ widely in their personal, medical and cultural characteristics. The members of the Task Force have participated independently in the preparation of these guidelines, drawing on their academic and clinical experience and by objective examination and interpretation of all available literature. A disclosure of their potential conflict of interest is reported on the websites of the ESH and the ESC.

RESUMO

BACKGROUND: Acute dyspnea is one of the main reasons for admission to Emergency Department (ED). Availability of ultraminiaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. The aim of this study was to identify an integrated ultrasound approach for diagnosis of acute heart failure (acute HF), using PUD and combining evaluation from lung, heart and inferior vena cava (IVC). METHODS: We included 102 patients presenting to the ED of "Antonio Cardarelli" Hospital in Naples (Italy) for acute dyspnea (AD). All patients underwent integrated ultrasound examination (IUE) of lung-heart-IVC, using PUD. The gold standard was the final diagnosis determined by two expert reviewers: acute heart failure (acute HF) or noncardiac dyspnea. We used 2 × 2 contingency tables to analyze sensitivity, specificity, positive and negative predictive value and accuracy of the three ultrasonic methods, and their combinations for the diagnosis of acute HF, comparing with the final, validated diagnosis. RESULTS: Lung ultrasound (LUS) alone exhibited a good sensitivity (100%) and specificity (82%) and had the highest accuracy (89%) among single modalities (heart and IVC) for the diagnosis of acute HF. The highest accuracy among all methods (96%) was obtained by the combination of positive LUS and either dilated left atrium or EF ≤ 40% or both (all P < .01 vs single modalities). CONCLUSION: In patients presenting to ED, IUE using PUD is a useful extension of clinical examination and has a reliable diagnostic discriminant ability in the immediate evaluation of acute dyspnea. The combination of positive LUS with focused cardiac ultrasonography (FoCUS), including also dilated left atrium, substantially extends the spectrum of recognizable acute HF.

RESUMO

Reexpansion pulmonary edema (RPE) is an uncommon complication of thoracentesis or chest drainage. It occurs in the ipsilateral or contralateral lung. Causes, pathogenesis and therapy are not well understood especially for contralateral RPE. We describe a case of fatal contralateral RPE in a 59-years-old woman with right lung cancer underwent ultrasound-guided thoracentesis for massive pleural effusion and severe dyspnea. Pathogenesis of contralateral RPE is probably multifactorial and in this case is mostly due to the overperfusion of the healthy lung and consequent capillary damage. The right therapy for this condition is not known.

RESUMO

This study concerns the expression of biomarkers involved in diverse pathways, such as progression, DNA repair mechanisms and angiogenesis to establish an immunoprofile capable of characterizing sporadic versus familial breast cancers (BCs). The aim was to identify a patient subgroup with a different clinical outcome, which could then be directed towards new targeted therapies. Hierarchical cluster analysis (HCA) was carried out using the immunohistochemical score from tissue microarray sections of an initial cohort of 183 (88 sporadic and 95 familial) patients with invasive BC. For the survival analysis, only those patients with complete follow-up were considered. The HCA revealed a 16-protein immunoprofile, nine of which represent the core, as was also found when familial and sporadic BCs were analysed individually. The 16-biomarker immunoprofile was able to identify a group of patients (Group 1) with a more aggressive tumour phenotype. Survival analyses showed that VEGF+ /TWIST1- patients with familial BC of Group 1 tended to demonstrate a lower DFS than the VEGF- /TWIST1+ sporadic BC patients of Group 2 (p = 0.052). Moreover, the entire cohort of VEGF+ /TWIST1- patients showed a statistically worse DFS than the patients with VEGF- /TWIST1+ expression (p = 0.034). In conclusion, we found that tumour stratification based on an immunoprofile is useful to predict the patient clinical behaviour. In particular, our study indicates that the clustering of tumors on the basis of this immunoprofile suggests the possibility to differentiate familial from sporadic BCs and to clinically select those patients who are more likely to benefit from inhibition of the VEGF pathway.

RESUMO

BACKGROUND: Recent analyses in a registry of hypertensive patients suggested that preceding left ventricular (LV) hypertrophy (LVH) and/or carotid atherosclerosis are associated with incident type 2 diabetes, independent of confounders. We assess the relation between prevalent cardio-renal target organ damage (TOD) and subsequent incident type 2 diabetes in a population-based study with high prevalence of obesity. METHODS: We selected 2887 non-diabetic participants from two cohorts of the Strong Heart Study (SHS). Clinical exam, laboratory tests and echocardiograms were performed. Adjudicated TODs were LVH, left atrium (LA) dilatation, and high urine albumin/creatinine ratio (UACR). Multivariable logistic regression models were used to identify variables responsible for the association between initial TODs and incident diabetes at 4-year follow-up (FU). RESULTS: After 4 years, 297 new cases of diabetes (10%) were identified, 216 of whom exhibited baseline impaired fasting glucose (IFG, 73%, p < 0.0001). Participants developing type 2 diabetes exhibited higher inflammatory markers, fat-free mass and adipose mass and higher prevalence of initial LVH and LA dilatation than those without (both p < 0.04). In multivariable logistic regression, controlling for age, sex, family relatedness, presence of arterial hypertension and IFG, all three indicators of TOD predicted incident diabetes (all p < 0.01). However, the effects of TOD was offset when body fat and inflammatory markers were introduced into the model. CONCLUSIONS: In this population-based study with high prevalence of obesity, TOD precedes clinical appearance of type 2 diabetes and is related to the preceding metabolic status, body composition and inflammatory status.

RESUMO

Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e.g. hypokalaemia, hypomagnesemia), further contributing to arrhythmias, whereas effective control of blood pressure may prevent the development of the arrhythmias such as AF. In recognizing this close relationship between hypertension and arrhythmias, the European Heart Rhythm Association (EHRA) and the European Society of Cardiology (ESC) Council on Hypertension convened a Task Force, with representation from the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS), and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE), with the remit to comprehensively review the available evidence to publish a joint consensus document on hypertension and cardiac arrhythmias, and to provide up-to-date consensus recommendations for use in clinical practice. The ultimate judgment regarding care of a particular patient must be made by the healthcare provider and the patient in light of all of the circumstances presented by that patient.

RESUMO

BACKGROUND: The availability of ultra-miniaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. Information on accuracy of ultrasound with handheld units in immediate differential diagnosis in emergency department (ED) is poor. The aim of this study is to test the usefulness and accuracy of lung ultrasound (LUS) alone or combined with ultrasound of the heart and inferior vena cava (IVC) using a PUD for the differential diagnosis of acute dyspnea (AD). METHODS: We included 68 patients presenting to the ED of "Maurizio Bufalini" Hospital in Cesena (Italy) for AD. All patients underwent integrated ultrasound examination (IUE) of lung-heart-IVC, using PUD. The series was divided into patients with dyspnea of cardiac or non-cardiac origin. We used 2 × 2 contingency tables to analyze sensitivity, specificity, positive predictive value and negative predictive value of the three ultrasonic methods and their various combinations for the diagnosis of cardiogenic dyspnea (CD), comparing with the final diagnosis made by an independent emergency physician. RESULTS: LUS alone exhibited a good sensitivity (92.6%) and specificity (80.5%). The highest accuracy (90%) for the diagnosis of CD was obtained with the combination of LUS and one of the other two methods (heart or IVC). CONCLUSIONS: The IUE with PUD is a useful extension of the clinical examination, can be readily available at the bedside or in ambulance, requires few minutes and has a reliable diagnostic discriminant ability in the setting of AD.

RESUMO

We tested the prognostic impact of a marker of arterial stiffness, pulse pressure/stroke volume index (PP/SVi), in patients with hypertension and left ventricular (LV) hypertrophy. We used data from 866 patients randomized to losartan or atenolol-based antihypertensive treatment, over a median of 4.8 years, in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study. The association of PP/SVi with outcomes was tested in Cox regression analyses and reported as hazard ratio (HR) and 95% confidence intervals (CI). In multivariate regression, reduction of PP/SVi was independently associated with male gender, reduction in systolic blood pressure (BP) and relative wall thickness and with an increase in left ventricular ejection fraction (all p < .05). After adjusting for confounders, higher baseline PP/SVi predicted a 38% higher hazard of combined major fatal and non-fatal cardiovascular events (95% CI 1.04-1.84), and higher hazard of cardiovascular mortality (HR 2.35 (95% CI 1.59-3.48) and stroke (HR 1.45 (95% CI 1.06-1.99) (all p < .05). Higher PP/SVi also predicts higher rate of hospitalization for HF (HR 2.15 (95% CI 1.48-3.12) and a 52% higher hazard of all-cause mortality (95% CI 1.10-2.09) (both p < .05). In hypertensive patients with electrocardiographic LV hypertrophy, higher PP/SVi was associated with increased cardiovascular morbidity and mortality.
