Differential associations between abnormal cardiac left ventricular geometry types and cerebral white matter disease. J Stroke Cerebrovasc Dis 2024; 33:107709.

Abstract
OBJECTIVES Reduced cardiac outflow due to left ventricular hypertrophy has been suggested as a potential risk factor for development of cerebral white matter disease. Our study aimed to examine the correlation between left ventricular geometry and white matter disease volume to establish a clearer understanding of their relationship, as it is currently not well-established. METHODS Consecutive patients from 2016 to 2021 who were ≥18 years and underwent echocardiography, cardiac MRI, and brain MRI within one year were included. Four categories of left ventricular geometry were defined based on left ventricular mass index and relative wall thickness on echocardiography. White matter disease volume was quantified using an automated algorithm applied to axial T2 FLAIR images and compared across left ventricular geometry categories. RESULTS We identified 112 patients of which 34.8 % had normal left ventricular geometry, 20.5 % had eccentric hypertrophy, 21.4 % had concentric remodeling, and 23.2 % had concentric hypertrophy. White matter disease volume was highest in patients with concentric hypertrophy and concentric remodeling, compared to eccentric hypertrophy and normal morphology with a trend-P value of 0.028. Patients with higher relative wall thickness had higher white matter disease volume (10.73 ± 10.29 cc vs 5.89 ± 6.46 cc, P = 0.003), compared to those with normal relative wall thickness. CONCLUSION Our results showed that abnormal left ventricular geometry is associated with higher white matter disease burden, particularly among those with abnormal relative wall thickness. Future studies are needed to explore causative relationships and potential therapeutic options that may mediate the adverse left ventricular remodeling and its effect in slowing white matter disease progression.

Left ventricular hypertrophy as a risk factor for accelerated brain aging: Results from the Study of Health in Pomerania. Hum Brain Mapp 2024; 45:e26567.

Abstract
Previous studies provided evidence for the importance of cardiac structure abnormalities, in particular greater left ventricular (LV) mass, for brain aging, but longitudinal studies are lacking to date. We included 926 individuals (median age 48 years; 53% women) from the TREND cohort of the Study of Health in Pomerania (SHIP) without reduced ejection fraction or a history of myocardial infarction. LV mass index (LVMI) was determined by echocardiography at baseline. Brain morphometric measurements were derived from magnetic resonance images at baseline and 7-year follow-up. Direct effects of baseline LVMI on brain morphometry at follow-up were estimated using linear regression models with adjustment for baseline brain morphometry. At baseline, median LVMI was 40 g/m2.7 and 241 individuals (26%) met the criterion of LV hypertrophy. After correction for multiple testing, baseline LVMI was directly associated with reduced global cortical thickness and increased cortical brain age at follow-up independent from hypertension and blood pressure. Exposure-outcome relations were nonlinear and significantly stronger in the upper half of the exposure distribution. Specifically, an increase in baseline LVMI from the 50% quantile to the 95% quantile was associated additional 2.7 years (95% confidence interval = [1.5 years, 3.8 years]) of cortical brain age at follow-up. Additional regional analyses yielded bilateral effects on multiple frontal cortical regions. Our findings highlight the role of cardiac structure in brain aging. LVMI constitutes an easily measurable marker that might help to identify persons at risk for cognitive impairment and dementia.

Abstract
The association between raised blood pressure and increased risk of subsequent cognitive decline is well known. Left ventricular hypertrophy (LVH), as a marker of hypertensive target organ damage, may help identify those at risk of cognitive decline. We assessed whether LVH was associated with subsequent cognitive decline or dementia in hypertensive participants aged ≥80 years in the randomized, placebo-controlled Hypertension in the Very Elderly Trial. LVH was assessed using 12-lead electrocardiography (ECG) based on the Cornell Product (CP-LVH), Sokolow-Lyon (SL-LVH), and Cornell Voltage (CV-LVH) criteria. The Mini-Mental State Examination (MMSE) was used to assess cognitive function at baseline and annually. A fall in MMSE to <24 or an annual fall of >3 points were defined as cognitive decline and triggered dementia screening (Diagnostic Statistical Manual IV). Death was defined as a competing event. Fine-Gray regression models were used to examine the relationship between baseline LVH and cognitive outcomes. There were 2645 in the analytical sample, including 201 (7.6%) with CP-LVH, 225 (8.5%) SL-LVH and 251 (9.5%) CV-LVH. CP-LVH was associated with increased risk of cognitive decline, subdistribution hazard ratio (sHR)1.3 (95% confidence interval (CI) 1.01-1.67) in multivariate analyses. SL-LVH and CV-LVH were not associated with cognitive decline (sHR1.06 (95% CI 0.82-1.37) and sHR1.13 (95% CI 0.89-1.43), respectively). LVH was not associated with dementia. LVH may be related to subsequent cognitive decline, but evidence was inconsistent depending on ECG criterion and there were no associations with incident dementia. Additional work is needed to understand the relationships between blood pressure, LVH assessment and cognition.

Abstract
BACKGROUND Left ventricular hypertrophy (LVH) and carotid atherosclerosis (CAS) have been identified as factors associated with cognitive impairment (CI) but have not been studied in patients undergoing peritoneal dialysis (PD). This study investigated the relationship between LVH and CAS and cognitive function in patients undergoing PD. METHODS In this single-center cross-sectional study, the clinically stable patients who were over 18 years of age and had undergone PD for at least 3 months were enrolled. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), which included seven areas: visuospatial/executive function, naming, attention, language, abstraction, delayed recall, and orientation. LVH was defined as LVMI > 46.7 g/m2.7 in women and LVMI > 49.2 g/m2.7 in men. CAS was defined as carotid intima-media thickness ≥ 1.0 mm and/or the presence of plaque. RESULTS A total of 207 patients undergoing PD were recruited, with an average age of 52.14 ± 14.93 years and a median PD duration of 8 months (5-19 months). The CI rate was 56%, and the prevalence of CAS was 53.6%. LVH occurred in 110 patients (53.1%). Patients in the LVH group tended to be older, and had a higher body mass index, a higher pulse pressure, a higher male proportion, a lower ejection fraction, a higher prevalence of cardiovascular disease and CI, and a lower MoCA scores.Multivariate logistic regression analysis was conducted to analyze the association between LVH and CI (OR, 10.087; 95% confidence interval, 2.966-34.307). And the association between LVH and CI was still supported after propensity matching scores. CAS was not significantly associated with CI. CONCLUSION LVH is independently associated with CI in patients undergoing PD, while CAS is not significantly associated with CI.

Abstract
BACKGROUND Markers of altered cardiac function might predict cognitive decline and dementia. OBJECTIVE This systematic review aims to review the literature that examines the associations of various electrocardiogram (ECG) markers with cognitive decline and dementia in middle-aged and elderly populations. METHODS We searched PubMed, Embase, and Web of Science through 1 July 2020 for literature and conducted a systematic literature review. We included studies examining the associations of ECG markers (e.g., left ventricular hypertrophy [LVH], spatial QRS-T angle, and QT prolongation) with cognitive function and dementia in adult populations regardless of study setting and design, but excluded studies examining atrial fibrillation and heart rate variability. RESULTS Fourteen community-based cross-sectional and longitudinal studies were identified. ECG markers were investigated in association with dementia in four prospective studies, and with cognitive decline in ten prospective studies. ECG-assessed LVH was associated with dementia in one study while five heterogeneous prospective studies yielded inconsistent associations with cognitive decline. Regarding ventricular repolarization markers, spatial QRS-T angle was associated with cognitive decline in one study while another study found no association between QT prolongation and cognitive decline. High resting heart rate was associated with both dementia and cognitive decline in one study but not associated with dementia in another study. P-wave abnormality was significantly associated with incident dementia and cognitive decline in one prospective study. CONCLUSION Some ECG markers were associated with incident dementia and cognitive decline. However, limited number of heterogeneous studies did not allow us to make firm conclusions. Further studies are needed.

Abstract
Background Hypertrophy of the left ventricle (LV) has recently been associated with adverse changes of brain structure in older adults, notably increased burden of white matter hyperintensities (WMHs). Whether greater LV size or mass is also related to WMH burden in middle‐aged adults is currently unclear. In addition, its relation with alterations in cortical thickness (CT) has not been studied to date. Methods and Results Data from 1602 participants of the population‐based SHIP (Study of Health in Pomerania) with LV ejection fraction >40% and no history of myocardial infarction were included (aged 21–82 years; median age, 49 years; 53% women). Participants underwent both echocardiography and magnetic resonance imaging of the head. Imaging markers of brain aging (ie, CT and WMH volume) were determined from magnetic resonance imaging scans. LV mass and diameter were associated with lower global CT and greater WMH volume, while adjusting for age, sex, body height, fat‐free body mass, and intracranial volume. Moreover, thicknesses of the interventricular septum and posterior wall were also associated with lower global CT. These associations could not be explained by cardiovascular risk factors (including hypertension), inflammatory markers, or sociodemographic factors. Regional analyses showed distinct spatial patterns of lower CT in association with LV diameter and posterior wall thickness. Conclusions LV diameter and mass are associated with lower global and regional CT as well as greater WMH burden in the general population. These findings highlight the brain structural underpinnings of the associations of LV hypertrophy with cognitive decline and dementia.

Abstract
PURPOSE OF REVIEW Echocardiography is a noninvasive tool of choice for evaluating cardiac structure and function in numerous cardiac conditions ranging from congenital heart disease, myocardial diseases, coronary artery disease (CAD), valvulopathies, arrhythmias, and pericardial disorders. We review the prognostic significance of echocardiographic indices of cardiac remodeling in the general population. RECENT FINDINGS Recent meta-analyses have confirmed the prognostic significance of echocardiographic measurements (left ventricular mass/hypertrophy, systolic and diastolic dysfunction, left atrial dimensions and function, and strain rate measures) in asymptomatic people in the community for adverse clinical outcomes including CAD, stroke, heart failure, atrial fibrillation, sudden death, and all-cause mortality. The clinical utility of screening echocardiography has been examined comprehensively in hypertensive patients, where it is challenged by measurement variability. Echocardiographic measures predict cardiovascular disease outcomes consistently in multiple community-based epidemiological studies. However, the clinical utility of screening asymptomatic individuals with echocardiography in population-based settings is limited.

Abstract
Vascular dementia (VD) is one of the leading causes of dementia, and hypertension is a known risk factor for VD. Hypertension treatment guidelines have previously discussed an optimal blood pressure goal to prevent further cardiovascular complications with long-term management. The treatment of hypertension can prevent stroke, kidney failure, and perhaps prevent cognitive decline as well. We reviewed studies that demonstrated an association between hypertension and cognitive impairment (CI). The role of antihypertensive medications (AHM) in preventing CI was also investigated. This topic is worth exploring as dementia has high healthcare costs and will become prominent as the population in the United States ages. We used the medical subject heading (MeSH) search strategy on Pubmed and reviewed 22 articles. The studies showed that there might be a link between hypertension, AHM, and CI. The studies did not suggest a superiority of any specific AHM class to prevent CI. Further research on optimal hypertension treatment goals to prevent cognitive impairment and dementia is recommended.

Abstract
INTRODUCTION Cognitive decline and dementia recognize multiple risk factors and pathophysiological mechanisms, often involved simultaneously with complex interactions. Several studies have shown that both arterial hypertension and hypotension are associated with a greater risk of cognitive decline and dementia, but clinical evidence on this point is conflicting. Our aim was to conduct an umbrella review on cognitive function, dementia, and blood pressure, with particular attention to epidemiological, prognostic and therapeutic aspects. EVIDENCE ACQUISITION We conducted a dedicated literature search on PubMed for systematic reviews and meta-analyses that focused on arterial pressure, hypertension, hypotension and similar conditions, and cognitive function, cognitive decline and dementia. The internal validity of systematic reviews and meta-analyses was formally analyzed using the OQAQ tool. The umbrella review was planned in accordance with current international recommendations and was described as specified by the PRISMA guidelines. EVIDENCE SYNTHESIS Seventeen systematic reviews (including 13 meta-analyses) were included, for a total of 675 clinical studies and over 1 million patients. Hypertension results to be associated with a lower risk of Alzheimer's dementia, greater risk of vascular dementia and greater risk of cognitive decline. Orthostatic hypotension seems to be associated with greater risk of Alzheimer's dementia, vascular dementia and dementia of Parkinson's disease. Therapy with acetylcholinesterase inhibitors produces lower risk of cardiovascular events, greater risk of hypertension and greater risk of bradycardia, while the anti-hypertensive therapy leads to a lower risk of dementia of all types and lower risk of cognitive decline. CONCLUSIONS To date, the evidence on the relationship between blood pressure, cognitive decline and dementia provides somewhat heterogeneous data. Further studies are clearly needed, with explicit inclusion criteria as objective as possible, adequate follow-up and precise characterization of implemented cardiovascular and cognitive treatments.

Abstract
Background and Purpose Left ventricular hypertrophy (LVH) is associated with the risk of stroke and dementia independently of other vascular risk factors, but its association with cerebral small vessel disease (CSVD) remains unknown. Here, we employed a systematic review and meta-analysis to address this gap. Methods Following the MOOSE guidelines (PROSPERO protocol: CRD42018110305), we systematically searched the literature for studies exploring the association between LVH or left ventricular (LV) mass, with neuroimaging markers of CSVD (lacunes, white matter hyperintensities [WMHs], cerebral microbleeds [CMBs]). We evaluated risk of bias and pooled association estimates with random-effects meta-analyses. Results We identified 31 studies (n=25,562) meeting our eligibility criteria. In meta-analysis, LVH was associated with lacunes and extensive WMHs in studies of the general population (odds ratio [OR]lacunes, 1.49; 95% confidence interval [CI], 1.12 to 2.00) (ORWMH, 1.73; 95% CI, 1.38 to 2.17) and studies in high-risk populations (ORlacunes: 2.39; 95% CI, 1.32 to 4.32) (ORWMH, 2.01; 95% CI, 1.45 to 2.80). The results remained stable in general population studies adjusting for hypertension and other vascular risk factors, as well as in sub-analyses by LVH assessment method (echocardiography/electrocardiogram), study design (cross-sectional/cohort), and study quality. Across LV morphology patterns, we found gradually increasing ORs for concentric remodelling, eccentric hypertrophy, and concentric hypertrophy, as compared to normal LV geometry. LVH was further associated with CMBs in high-risk population studies. Conclusions LVH is associated with neuroimaging markers of CSVD independently of hypertension and other vascular risk factors. Our findings suggest LVH as a novel risk factor for CSVD and highlight the link between subclinical heart and brain damage.

Abstract
PURPOSE OF REVIEW This is a review of ambulatory blood pressure monitoring (ABPM) use in pediatrics, summarizing current knowledge and uses of ABPM. RECENT FINDINGS Updated guidelines from the American Academy of Pediatrics have emphasized the value of ABPM. ABPM is necessary to diagnose white coat hypertension, masked hypertension, and nocturnal hypertension associated with specific conditions. There is growing evidence that ABPM may be useful in these populations. ABPM has been demonstrated to be more predictive of end-organ damage in pediatric hypertension compared to office blood pressure. ABPM is an important tool in the diagnosis and management of pediatric hypertension. Routine use of ABPM could potentially prevent early cardiovascular morbidity and mortality in a wide variety of populations.

Abstract
Hypertension is a risk factor for cardiovascular morbidity and mortality with increasing prevalence with age, whose treatment is associated with benefits over fatal and non-fatal cardiovascular events even later in life. However, there are persistent concerns on the short- and long-term weighted benefits of treating hypertension in the very old, particularly in those with specific clinical features. In fact, a broad range of clinical scenarios can be observed at older ages, spanning from the healthy to the frailest patient, and hypertension clinical trials have traditionally excluded the latter, thus preventing the unconditioned application to these patients of the same recommendations as in younger ages. Persistent issues regarding high blood pressure management in the very old adult are mainly related to treatment threshold and targets, which have been differently addressed by American and European guidelines. Herein, we will examine the challenges related to high blood pressure treatment in healthy and frail older and very old adults. We will discuss the evidence behind current recommendations. Finally, we will recapitulate the recommended treatment options for high blood pressure in these patients in the light of the most recent guidelines.

Hypertension-induced cognitive impairment: insights from prolonged angiotensin II infusion in mice. Hypertens Res 2018; 41:817-827. [PMID: 30120397 DOI: 10.1038/s41440-018-0090-9] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2017] [Revised: 02/23/2018] [Accepted: 03/25/2018] [Indexed: 01/13/2023]
Abstract
The causal relation between hypertension and cerebral small vessel disease (cSVD) remains elusive, and appropriate animal models are scarce. We aimed to assess the relevance of prolonged angiotensin II-induced hypertension in mice for the study of cSVD.Adult male C57BL/6 mice were continuously infused for 3 months with Angiotensin II (Ang II; 2 µg/kg/min, sc) or saline (control) via osmotic minipumps. Blood pressure, neurological function, locomotor activity, and working memory (Y-maze alternation task) were assessed throughout the study. Short-term memory performance (object location task) was measured after 3 months of infusion. Blood-brain barrier (BBB) function was assessed by the presence of IgG leakage and quantified in each brain area of interest. Microglial activation and myelin loss were studied in the areas of leakage.Systolic blood pressure increased and remained elevated over the 3 months of Ang II infusion, while neurological scores and locomotor activity did not change. Working memory performance was also not changed, yet short-term memory performance was impaired in Ang II-treated mice compared to controls. While BBB leakages were present in both groups, mainly in the neocortex, hippocampus, and cerebral nuclei, Ang II-treated mice showed greater leakage than control mice, along with greater microglial density and soma size. Myelin loss was observed for the largest leaks.Prolonged Ang II-induced hypertension is associated with large BBB leaks, microglial activation, myelin loss, and memory dysfunction in the absence of stroke.

Abstract
Multiple cardiac pathologies have been shown to contribute to progressive cognitive decline and dementia in elderly populations, including left ventricular hypertrophy (LVH), a marker of prolonged exposure to hypertension. Although associations between chronic hypertension and cognitive function are thought to be mediated primarily by these end organ effects, there is increasing evidence that early changes in cardiac structure and function, such as LVH, may independently contribute to cognitive decline and impairment. In the current issue of the Journal of Alzheimer's Disease, Mahinrad and colleagues report important new findings on the association between LVH and cognitive function that are incremental to cardiovascular risk and co-morbidity, including hypertension. Emerging evidence that early changes in cardiac structure and function may independently contribute to cognitive decline in elderly populations has resulted in an increased interest in these preclinical substrates as potential treatment targets for the prevention of cognitive decline and in their putative contributions to the pathogenesis of dementia.
