Cardiovascular prognosis in patients admitted to an emergency department with hypertensive emergencies and urgencies.

BACKGROUND: At present, few data are available on the prognosis of hypertensive emergencies and urgencies admitted to emergency departments. AIM: The aim of our study was to evaluate the incidence of total and cardiovascular events during follow-up in hypertensive patients admitted to the emergency departments of Brescia Hospital (Northern Italy) with hypertensive emergencies or urgencies from 1 January to 31 December 2015. METHODS: Medical records of patients aged more than 18 years, admitted to the emergency department with SBP values at least 180 mmHg (SBP) and/or DBP values at least 120 mmHg (DBP) were collected and analysed (18% of patients were classified as 'hypertensive emergency' and 82% as 'hypertensive urgency'). Data in 895 patients (385 men and 510 women, mean age 70. 5 ±â€Š15 years) were analysed; the mean duration of follow-up after admission to the emergency department was 12 ±â€Š5 months. RESULTS: During the follow-up, 96 cardiovascular events (28 fatal) occurred (20 cardiac events, 30 cerebrovascular events, 26 hospital admission for heart failure, 20 cases of new onset kidney disease). In 40 patients (4.5%), a new episode of acute blood pressure rise with referral to the emergency department was recorded. Cardiovascular mortality and morbidity were greater in patients with a previous hypertensive emergency (14.5 vs. 4.5% in patients with hypertensive emergency and urgency, respectively, chi-square, P < 0.0001). Similar results were obtained when the occurrence of cerebrovascular or renal events were considered separately. CONCLUSION: Admission to the emergency department for hypertensive emergencies and urgencies identifies hypertensive patients at increased risk for fatal and nonfatal cardiovascular events. Our findings add some new finding suggesting that further research in this field should be improved aiming to define, prevent, treat and follow hypertensive urgencies and emergencies.

Microvascular Structural Alterations in Cancer Patients Treated With Antiangiogenic Drugs.

Objective: Antiangiogenic therapies (tyrosine kinase inhibitors-TKI and direct anti-VEGF monoclonal antibodies) are being increasingly used in the treatment of solid tumors; hypertension represents a common side effect of these agents. Several mechanisms are involved in the development of hypertension, including microvascular rarefaction and other microvascular alterations. Therefore, the aim of our study was to evaluate whether TKI and direct anti-VEGF agents may affect the structure of retinal arterioles or capillary density. Design and Methods: We investigated 20 patients with a diagnosis of cancer who underwent a treatment with either a TKI or an anti-VEGF antibody. Patients were submitted to ambulatory monitoring blood pressure for blood pressure evaluation. Basal and total capillary density were assessed by capillaroscopy whereas, retinal arteriole morphology was measured by Adaptive Optics. Patients were evaluated before starting the antiangiogenic therapy (T0) and re-evaluated after 3 (T3) and 6 (T6) months after treatment. Fourteen patients completed the study. Results: Systolic and diastolic blood pressure values were similar in all patients at T3 and T6 compared to T0. However, during the study antihypertensive treatment was optimized (increased dose and/or addition of drugs) in 57% of patients (n = 8). No differences were observed in retinal arteriole structural parameters and in large artery stiffness. Basal capillary density was reduced by antiangiogenic drugs after 3 or 6 months. Conclusions: Our data suggest that an increase of antihypertensive treatment is necessary in patients treated with a TKI or a direct VEGF inhibitor, confirming pro-hypertensive effects of these drugs. However, under adequate blood pressure control, microvascular structure seem to be partially preserved, since a worsening of basal capillary density but no changes in retinal arteriole morphology were observed.

Effect of direct renin inhibition on vascular function after long-term treatment with aliskiren in hypertensive and diabetic patients.

OBJECTIVE: We tested the hypothesis that chronic treatment with the direct renin inhibitor aliskiren improves vascular function in resistance and conduit arteries of type two diabetic and hypertensive patients. METHOD: Sixteen patients with mild essential hypertension and with a previous diagnosis of noninsulin-dependent diabetes mellitus were included in the study. Patients were then randomized to aliskiren (150 mg once daily, n = 9), or ramipril (5 mg once daily, n = 7). Each patient underwent a biopsy of the subcutaneous tissue and small arteries were dissected and mounted on a pressurized micromyograph to evaluate endothelium dependent vasorelaxation in response to acetylcholine ±â€ŠN omega-nitro-L-arginine methyl ester hydrochloride in vessels precontracted with norepinephrine. Endothelial function has been quantified also in large conduit arteries by flow-mediated dilation. RESULTS: A similar office blood pressure-lowering effect was observed with the two drugs, although changes in DBP were not statistically significant in the ramipril group. Aliskiren significantly improved endothelium-dependent relaxation in subcutaneous resistance arteries, as well as increased flow-mediated dilation in conduit arteries, whereas the effects induced by ramipril did not reach statistical significance. Only aliskiren significantly increased the expression of p1177-endothelial nitric oxide synthase in the endothelium. Both aliskiren and ramipril had a negligible effect on markers of oxidative stress. CONCLUSION: Aliskiren restored endothelial function and induced a more prompt peripheral vasodilation in hypertensive and diabetic patients possibly through the increased production of nitric oxide via the enhanced expression and function of the active phosphorylated form of endothelial nitric oxide synthase.

Clinical characteristics and risk factors for mortality in hematologic patients affected by COVID-19.

BACKGROUND: Patients with cancer are considered highly vulnerable to the recent coronavirus disease 2019 (COVID-19) pandemic. However, there are still few data on COVID-19 occurring in hematologic patients. METHODS: One hundred two patients with COVID-19 symptoms and a nasopharyngeal swab positive for severe acute respiratory syndrome coronavirus 2 seen at 2 hematologic departments located in Lombardy, Italy, during March 2020 were studied. Risk factors for acquiring COVID-19 were analyzed by comparisons of patients with COVID-19 and the standard hematologic population managed at the same institutions in 2019. Thirty-day survival was compared with the survival of matched uninfected control patients with similar hematologic disorders and nonhematologic patients affected by COVID-19. RESULTS: Male sex was significantly more prevalent in patients with COVID-19. The infection occurred across all different types of hematologic disease; however, the risk of acquiring a COVID-19 infection was lower for patients with chronic myeloproliferative neoplasms, including chronic myeloid leukemia, and higher for patients with immune-mediated anemia on immunosuppressive-related treatments. The 30-day mortality rate was 39.2%, which was higher than the rates for nonhematologic patients with COVID-19 (23.5%; P = .02) and uninfected hematologic controls (3%; P < .001). The severity of the respiratory syndrome at presentation and active hematologic treatment were independently associated with a worse prognosis. Neither diagnosis nor disease status affected the prognosis. The worst prognosis was demonstrated among patients on active hematologic treatment and those with more severe respiratory syndrome at COVID-19 presentation. CONCLUSIONS: During the COVID-19 pandemic, patients should be advised to seek medical attention at the earliest signs of dyspnea and/or respiratory infection. Physicians should perform a risk-benefit analysis to determine the impact of temporarily deferring nonlifesaving treatments versus the risk of adverse outcomes associated with COVID-19. LAY SUMMARY: Coronavirus disease 2019 (COVID-19) infection occurs across all different types of hematologic disease; however, the risk of acquiring it is lower for patients with chronic myeloproliferative neoplasms, including chronic myeloid leukemia, and higher for patients with immune-mediated anemia on immunosuppressive treatment. The 30-day mortality rate is 39.2%, which is far higher than the rates for both uninfected hematologic controls (3%; P < .001) and nonhematologic patients with COVID-19 (23.5%; P = .02) despite matching for age, sex, comorbidities, and severity of disease. Variables independently associated with a worse prognosis are the severity of the respiratory syndrome at presentation and any type of active hematologic treatment. Neither diagnosis nor disease status influence the prognosis.

Acute blood pressure elevation associated with biological therapies for cancer: a focus on VEGF signaling pathway inhibitors.

INTRODUCTION: Treatment with biological agents interfering with mechanisms of angiogenesis, such as vascular endothelial growth factor (VEGF) signaling pathway (VSP) inhibitors, was associated with an enhanced risk of acute and severe blood pressure (BP) increase and development of hypertensive emergencies. Areas covered: The present article will review the scientific literature reporting hypertensive emergencies as a complication of biological treatment with VSP inhibitors. Hypertensive emergency is a life-threatening condition characterized by very high BP values (>180/110 mmHg) associated with acute organ damage. The exact mechanism of action is still incompletely clarified. Endothelial dysfunction following reduced bioavailability of nitric oxide has been hypothesized to play an important role in promoting hypertension and the occurrence of acute organ damage. Expert opinion: Prevention, prompt recognition and treatment of hypertensive emergencies associated with treatment with VSP-inhibitors are essential to reduce the risk of adverse events. Not infrequently, the occurrence of hypertensive emergency led to VSP treatment discontinuation, with potential negative consequences on patient overall survival. The present review aims at providing detailed knowledge for the clinician regarding this specific issue, which could be of high impact in usual clinical practice, given the increasing burden of indications to treatment with biological agents targeted to the VEGF pathway.

Management of VEGF-Targeted Therapy-Induced Hypertension.

PURPOSE OF REVIEW: From a physiological point of view, VEGFs (vascular endothelial growth factors) and their receptors (VEGFR) play a critical role in vascular development angiogenesis, endothelial function, and vascular tone. On the pathological side, VEGF-VEGFR signaling may induce dysregulated angiogenesis, which contributes to the growth and to the spread of tumors, being essential for neoplastic proliferation and invasion. RECENT FINDINGS: Pharmacological inhibition of VEGF-VEGFR is now a cornerstone in the treatment of many malignancies; however, treatment with VEGF inhibitors is commonly associated with an increase in blood pressure values. This side effect is strictly connected with the mechanism of action of these medications and might represent an index of therapy efficacy. The optimal management of this form of hypertension is, at present, not clear. Calcium channel blockers and renin-angiotensin system inhibitors probably represent the most appropriate classes of hypertensive dugs for the treatment of this condition; however, no conclusive data are presently available.

Hypertension and Organ Damage in Women.

An adequate cardiovascular (CV) prevention strategy in women should consider the acknowledgement of sex-specific risk factors, such as hypertension in pregnancy, the concomitant presence of autoimmune diseases and the benefit of evaluating subclinical organ damage and treating hypertension. In accordance to current guidelines, the diagnostic approach does not differ between men and women, although the cardiac response to pressure overload may suggest greater sensitivity in women, and may vary according to age, ethnic background and obesity, that potentiates the effect of hypertension on left ventricular (LV) hypertrophy. Several studies have observed peculiar abnormalities in LV systolic and diastolic function according to gender. The possible mechanisms that influence a different cardiac adaptation to chronic pressure overload in men and women are not fully understood, although hormonal status, and in particular the lack of estrogen effects after menopause may contribute to the cardiovascular adaptation response to increased afterload. The increase in LV mass in response to chronic pressure overload is associated with higher LV ejection fraction in women than in men and LV torsion is maintained with aging in women but not in men. Interstitial fibrosis may reduce circumferential shortening and early diastolic strain rate, in the presence of a preserved ejection fraction in women, favoring the development of heart failure with preserved ejection fraction. Changes in aortic stiffness with aging may influence cardiac structural and functional changes. Isolated systolic hypertension reflects an increase in aortic stiffness, is frequent in women and may be associated to a greater development of concentric LVH. The regression of hypertensive LVH is more difficult in women, and residual hypertrophy is more common in women than in men despite effective antihypertensive treatment and blood pressure control. Carotid atherosclerosis has been extensively investigated in men and women, showing that women usually develop carotid plaques after menopause, with smaller and less unstable plaques; however large and/or a hypoechogenic plaques are more strictly related to cerebrovascular events in women than in men. More advanced abnormalities in the subcutaneous microcirculation have been recently observed, and well translate in the evidence of more prevalent coronary microcirculation involvement in women ischemic heart disease. The prevalence of albuminuria and of reduced estimated glomerular filtration rate (eGFR < 60 ml/min/1.73) are respectively lower and higher in postmenopausal women than in men. Experimental data suggest the possible involvement of renin-angiotensin-aldosterone system and of T regulatory lymphocytes to this regard.

Changes in extracellular matrix in subcutaneous small resistance arteries of patients with essential hypertension.

BACKGROUND: In the development of hypertensive microvascular remodeling, a relevant role may be played by changes in extracellular matrix proteins. Aim of this study was the to evaluate some extracellular matrix components within the tunica media of subcutaneous small arteries in 9 normotensive subjects and 12 essential hypertensive patients, submitted to a biopsy of subcutaneous fat from the gluteal or the anterior abdominal region. PATIENTS AND METHODS: Subcutaneous small resistance arteries were dissected and mounted on an isometric myograph, and the tunica media to internal lumen ratio was measured. In addition, fibronectin, laminin, transforming growth factor-beta-1 (TGF-ß1) and emilin-1 contents within the tunica media were evaluated by immunofluorescence and relative immunomorphometrical analysis (immunopositivity % of area). The total collagen content and collagen subtypes within the tunica media were evaluated using both Sirius red staining (under polarized light) and immunofluorescence assay. RESULTS: Normotensive controls had less total and type III collagen in respect with hypertensive patients. Fibronectin and TGF-ß1 tunica media content was significantly greater in essential hypertensive patients, compared with normotensive controls, while laminin and emilin-1 tunica media content was lesser in essential hypertensive patients, compared with normotensive controls. A significant correlation was observed between fibronectin tunica media content and media to lumen ratio. CONCLUSIONS: Our results indicate that, in small resistance arteries of patients with essential hypertension, a relevant fibrosis may be detected; fibronectin and TGF-ß1 tunica media content is increased, while laminin and emilin-1 content is decreased; these changes might be involved in the development of small resistance artery remodeling in humans.

Obesity and ECG left ventricular hypertrophy.

AIM: Our aim was to investigate the prevalence and the prognostic significance for fatal and nonfatal cerebrovascular and cardiovascular events of different ECG criteria for left ventricular hypertrophy (LVH) in normal weight, overweight and obese patients in an adult Italian population. METHODS: A total of 18 330 adults (mean age 54 ±â€Š11 years, 55% women, 53% hypertensive patients) were analyzed from the Moli-sani cohort. Obesity was defined using the ATPIII criteria. ECG-LVH was defined according to 2013 ESC-ESH guidelines. RESULTS: The age and sex adjusted prevalence of ECG-LVH did not differ from normal weight patients to class 1-3 obesity patients, when Cornell-voltage criterion was used. In overweight and obese patients, as compared with normal weight patients, a progressively lower prevalence of ECG-LVH was observed when the Sokolow-Lyon index was used, whereas a higher prevalence was shown by using the aVL R-wave voltage (>11 and >5.7 mm) and the Cornell-voltage-QRS duration product. The incidence of cardiovascular events was significantly greater in patients with ECG LVH diagnosis by the Cornell voltage [hazard ratio 1.89, 95% confidence interval (CI) 1.05-3.39] and the Cornell product (hazard ratio 1.87, 95% CI 1.31-2.67). After adjusting for different confounders (age, sex, cigarette, hypertension, hypercholesterolemia, diabetes, income, education, occupational class and physical activity) and for BMI categories, only the Cornell product remained significantly associated with a higher incidence of cardiovascular events (hazard ratio 1.66; 95% CI 1.16-2.38). The predictive significance of different LVH criteria was assessed across BMI categories; after adjusting for confounders, no LVH criteria were significantly associated with an increased risk of cardiovascular events in obese patients; Cornell-product LVH remained an independent predictor of events in normal weight and overweight individuals (hazard ratio 2.63; 95% CI 1.10-6.28 and hazard ratio 2.72; 95% CI 1.52-4.25, respectively). CONCLUSION: Our results confirm that ECG LVH prevalence may differ according to the criteria used across BMI categories in a low cardiovascular risk cohort. The use of different LVH criteria according to BMI categories may improve cardiovascular risk stratification in a general population independently of several confounding factors.

Vascular alterations in apolipoprotein A-I amyloidosis (Leu75Pro). A case-control study.

BACKGROUND: Among hereditary amyloidoses, apolipoprotein A-I (APO A-I) amyloidosis (Leu75Pro) is a rare, autosomal dominant condition in which renal, hepatic, and testicular involvement has been demonstrated. OBJECTIVE: To investigate vascular structural as well as functional alterations. METHODS: In 131 carriers of the amyloidogenic Leu75Pro APO A-I mutation (mean age 52 + 16 years, 56 women) and in 131 subjects matched for age, sex, body mass index and clinic blood pressure (BP), arterial stiffness (pulse wave velocity, PWV) and carotid intima-media thickness (IMT) were measured. RESULTS: By definition no differences for age, sex, body mass index, and BP were observed. Meanmax IMT (Mmax-IMT) in the common (CC), bifurcation (BIF) and internal (ICA) carotid artery were comparable in the two groups. After adjustment for high-density lipoprotein cholesterol and renal function differences between the two groups, a lower meanmax-IMT was observed in APO A-I Leu75Pro mutation carriers than in controls (CC Mmax-IMT 0.87 ± 0.21 versus 0.93 ± 0.2 mm, p = 0.07; BIF Mmax-IMT 1.19 ± 0.48 versus 1.36 ± 0.46 mm, p = 0.025; ICA Mmax-IMT 0.9 ± 0.37 versus 1.02 ± 0.35 mm, p = 0.028). On the other hand, aortic stiffness was significantly greater in patients with APO A-I amyloidosis than controls (PWV 11.5 ± 2.9 and 10.7 ± 2.3 m/s, p < 0.05), even after adjusting for confounders. CONCLUSIONS: In carriers of the amyloidogenic Leu75Pro APO A-I mutation, a significant increase in arterial stiffness is observed; on the contrary, carotid artery IMT is comparable to that of control subjects. These results may add significant information to the clinical features of this rare genetic disorder.

Hypertension and acute myocardial infarction: an overview.

History of hypertension is a frequent finding in patients with acute myocardial infarction (AMI) and its recurring association with female sex, diabetes, older age, less frequent smoking and more frequent vascular comorbidities composes a risk profile quite distinctive from the normotensive ischemic counterpart.Antecedent hypertension associates with higher rates of death and morbid events both during the early and long-term course of AMI, particularly if complicated by left ventricular dysfunction and/or congestive heart failure. Renin-angiotensin-aldosterone system blockade, through either angiotensin-converting enzyme inhibition, angiotensin II receptor blockade or aldosterone antagonism, exerts particular benefits in that high-risk hypertensive subgroup.In contrast to the negative implications carried by antecedent hypertension, higher systolic pressure at the onset of chest pain associates with lower mortality within 1 year from coronary occlusion, whereas increased blood pressure recorded after hemodynamic stabilization from the acute ischemic event bears inconsistent relationships with recurring coronary events in the long-term follow-up.Whether antihypertensive treatment in post-AMI hypertensive patients prevents ischemic relapses is uncertain. As a matter of fact, excessive diastolic pressure drops may jeopardize coronary perfusion and predispose to new acute coronary events, although the precise cause-effect mechanisms underlying this phenomenon need further evaluation.

Determinants of the structure of resistance-sized arteries in hypertensive patients.

OBJECTIVE: It has been previously demonstrated that structural alterations of subcutaneous small resistance arteries of hypertensive patients, as indicated by an increased media to lumen (M/L) ratio, is the most potent predictor of cardiovascular events. The aim of the present study was to identify possible determinants of small resistance artery structure that may be evaluated with non-invasive approaches. MATERIALS AND METHODS: One hundred and ninety-nine subjects (normotensives, essential hypertensives and patients with secondary hypertension) were included in the present study. All subjects were submitted to a biopsy of subcutaneous fat from the gluteal or the anterior abdominal region. Small resistance arteries were dissected and mounted on an isometric myograph, and M/L ratio was measured. All patients underwent standard biochemical tests, clinic blood pressure measurement, standard echocardiography and 24-h ambulatory blood pressure measurement. Glomerular filtration rate (GFR) was calculated according to MDRD study formula and Cockroft's formula. RESULTS: Significant correlation was found between M/L ratio and, respectively: GFR calculated both with MDRD study formula and Cockroft-Gault formula, creatinine serum, blood urea nitrogen, glycaemia, circulating sodium, clinical pulse pressure, stroke volume to pulse pressure ratio, clinical systolic, diastolic and mean arterial pressure, daytime pulse pressure. However, in a multivariate regression analysis, only serum creatinine remained in the model, and proved to be an independent predictor of small artery structure. CONCLUSIONS: Indices of renal function and, probably, of large artery distensibility may be related to small arteries remodelling in hypertension.

Prognostic role of flow-mediated dilatation of the brachial artery in hypertensive patients.

BACKGROUND: The prognostic role of endothelial dysfunction, as evaluated by flow-mediated vasodilatation of the brachial artery, has been demonstrated in patients at very high risk. We aimed to investigate whether flow-mediated vasodilatation predicts cardiovascular events in uncomplicated hypertensive patients. METHODS AND RESULTS: A total of 172 prospectively identified uncomplicated hypertensive patients (age 56 +/- 8 years, 41% women, 48 with diabetes mellitus type 2) were studied. At baseline all patients were untreated and underwent baseline standard laboratory examination. A standard echocardiogram was performed for the evaluation of left ventricular anatomy and function and patients with systolic dysfunction or left ventricular wall motion abnormalities were excluded. Endothelial function was measured as flow-mediated vasodilatation of the brachial artery using high-resolution ultrasound. Patients were followed for 95 +/- 37 months (range 2-136 months). A first nonfatal or fatal cardiovascular event occurred in 32 patients. The incidence of cardiovascular events was 1.4 and 3.1 per 100 patient-years in patients with a flow-mediated vasodilatation below and above the median value (4.7%), respectively (P < 0.005 by the log-rank test). In Cox analysis, controlling for age, sex, glycemia, cholesterol, smoking, BMI, systolic and diastolic blood pressure at baseline and left ventricular mass index, a low flow-mediated vasodilatation conferred an increased risk of cardiovascular events (odds ratio 2.67, 95% confidence interval 1.17 to 6.1, P = 0.02). CONCLUSION: The presence of endothelial dysfunction, as evaluated by flow-mediated vasodilatation of the brachial artery, identifies hypertensive patients at increased risk of nonfatal and fatal cardiovascular events.

Inappropriate left ventricular mass in patients with primary aldosteronism.

Assessment of appropriateness of left ventricular mass (LVM) for a given workload may better stratify hypertensive patients. Inappropriate LVM may reflect the interaction of genetic and neurohumoral factors other than blood pressure playing a significant role in myocardial growth. Primary aldosteronism (PA) represents a clinical model useful in assessing the effect of aldosterone increase on LVM. The aim of this study was to evaluate the inappropriateness of LVM in patients with PA. In 125 patients with PA (54 females; adrenal hyperplasia in 73 and adenoma in 52 patients) and in 125 age-, sex-, and blood pressure-matched, essential hypertensive patients, echocardiography was performed. The appropriateness of LVM was calculated by the ratio of observed LVM to the predicted value using a reference equation. In all of the subjects plasma renin activity and aldosterone, as well as clinic and 24-hour blood pressure, were measured. The prevalence of inappropriate LVM was greater in patients with traditionally defined left ventricular hypertrophy (70% and 44%, respectively; P=0.02) but also in patients without left ventricular hypertrophy (17% and 9%, respectively; P=0.085). In PA patients, a correlation was observed between the ratio of observed:predicted LVM and the ratio of aldosterone:plasma renin activity levels (r=0.29; P=0.003) or the postinfusion aldosterone concentration (r=0.44; P=0.004; n=42). In conclusion, in patients with PA, the prevalence of inappropriate LVM is increased, even in the absence of traditionally defined left ventricular hypertrophy. The increase in aldosterone levels could contribute to the increase of LV mass exceeding the amount needed to compensate hemodynamic load.

Left ventricular concentric geometry during treatment adversely affects cardiovascular prognosis in hypertensive patients.

Left ventricular (LV) mass and geometry predict risk for cardiovascular events in hypertension. Regression of LV hypertrophy (LVH) may imply an important prognostic significance. The relation between changes in LV geometry during antihypertensive treatment and subsequent prognosis has not yet been determined. A total of 436 prospectively identified uncomplicated hypertensive subjects with a baseline and follow-up echocardiogram (last examination 72+/-38 months apart) were followed for an additional 42+/-16 months. Their family doctor gave antihypertensive treatment. After the last follow-up echocardiogram, a first cardiovascular event occurred in 71 patients. Persistence of LVH from baseline to follow-up was confirmed as an independent predictor of cardiovascular events. Cardiovascular morbidity and mortality were significantly greater in patients with concentric (relative wall thickness > or =0.44) than in those with eccentric geometry (relative wall thickness <0.44) in patients presenting with LVH (P=0.002) and in those without LVH (P=0.002) at the follow-up echocardiogram. The incidence of cardiovascular events progressively increased from the first to the third tertile of LV mass index at follow-up (partition values 91 and 117 g/m2), but for a similar value of LV mass index it was significantly greater in those with concentric geometry (OR: 4.07; 95% CI: 1.49 to 11.14; P=0.004 in the second tertile; OR: 3.45; 95% CI: 1.62 to 7.32; P=0.001 in the third tertile; P<0.0001 in concentric versus eccentric geometry). Persistence or development of concentric geometry during follow-up may have additional prognostic significance in hypertensive patients with and without LVH.
