Abstract
Although orthostatic hypotension (OH) has long been recognized as a manifestation of autonomic dysfunction, a growing body of literature has identified OH as a common comorbidity of hypertension. This connection is complex, related to pathophysiology in blood pressure regulation and the manner by which OH is derived as the difference between 2 blood pressure measurements. While traditional therapeutic approaches to OH among patients with neurodegenerative disorders focus on increasing upright blood pressure to prevent cerebral hypoperfusion, the management of OH among patients with hypertension is more nuanced; resting hypertension is itself associated with adverse outcomes among these patients. Although there is substantial evidence that intensive blood pressure treatment does not cause OH in the majority of patients with essential hypertension, some classes of antihypertensive agents may unmask OH in patients with an underlying autonomic impairment. Practical steps to manage OH among adults with hypertension start with (1) a thorough characterization of its patterns, triggers, and cause; (2) review and removal of aggravating factors (often pharmacological agents not related to hypertension treatment); (3) optimization of an antihypertensive regimen; and (4) adoption of a tailored treatment strategy that avoids exacerbating hypertension. These strategies include countermaneuvers and short-acting vasoactive agents (midodrine, droxidopa). Ultimately, further research is needed on the epidemiology of OH, the impact of hypertension treatment on OH, approaches to the screening and diagnosis of OH, and OH treatment among adults with hypertension to improve the care of these patients and their complex blood pressure pathophysiology.

Abstract
BACKGROUND AND OBJECTIVES Although orthostatic hypotension (OH) can be an early feature of autonomic dysfunction in isolated REM sleep behavior disorder (iRBD), no large-scale studies have examined the frequency of OH in iRBD. In this study, we prospectively evaluated the frequency of OH in a large multicenter iRBD cohort. METHODS Participants 18 years or older with video polysomnogram-confirmed iRBD were enrolled through the North American Prodromal Synucleinopathy consortium. All participants underwent 3-minute orthostatic stand testing to assess the frequency of OH, and a Δ heart rate/Δ systolic blood pressure (ΔHR/ΔSBP) ratio <0.5 was used to define reduced HR augmentation, suggestive of neurogenic OH. All participants completed a battery of assessments, including the Scales for Outcomes in Parkinson Disease-Autonomic Dysfunction (SCOPA-AUT) and others assessing cognitive, motor, psychiatric, and sensory domains. RESULTS Of 340 iRBD participants (65 ± 10 years, 82% male), 93 (27%) met criteria for OH (ΔHR/ΔSBP 0.37 ± 0.28; range 0.0-1.57), and of these, 72 (77%) met criteria for OH with reduced HR augmentation (ΔHR/ΔSBP 0.28 ± 0.21; range 0.0-0.5). Supine hypertension (sHTN) was present in 72% of those with OH. Compared with iRBD participants without OH, those with OH were older, reported older age of RBD symptom onset, and had worse olfaction. There was no difference in autonomic symptom scores as measured by SCOPA-AUT. DISCUSSION OH and sHTN are common in iRBD. However, as patients may have reduced autonomic symptom awareness, orthostatic stand testing should be considered in clinical evaluations. Longitudinal studies are needed to clarify the relationship between OH and phenoconversion risk in iRBD. TRIAL REGISTRATION INFORMATION ClinicalTrials.gov: NCT03623672; North American Prodromal Synucleinopathy Consortium.

Associations Between Head Injury and Subsequent Risk of Falls: Results From the Atherosclerosis Risk in Communities (ARIC) Study. Neurology 2023; 101:e2234-e2242. [PMID: 37816634 PMCID: PMC10727209 DOI: 10.1212/wnl.0000000000207949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 08/28/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Falls are a leading cause of head injury among older adults, but the risk of fall occurring after a head injury is less well-characterized. We sought to examine the association between head injury and subsequent risk of falls requiring hospital care among community-dwelling older adults. METHODS This analysis included 13,081 participants in the Atherosclerosis Risk in Communities Study enrolled in 1987-1989 and followed through 2019. The association of head injury (time-varying exposure, self-reported and/or ICD-9/10 code identified) with the risk of subsequent (occurring >1-month after head injury) falls requiring hospital care (ICD-9/10 code defined) was modeled using Cox proportional hazards regression. Secondary analyses included Fine and Gray proportional hazards regression to account for the competing risk of death, analysis of head injury frequency and severity, and formal testing for interaction by age, sex, and race. Models were adjusted for age, sex, race/center, education, military service, alcohol consumption, smoking, diabetes, hypertension, and psychotropic medication use. RESULTS The mean age of participants at baseline was 54 years, 58% were female, 28% were Black, and 14% had at least one head injury occurring over the study period. Over a median 23 years of follow-up, 29% of participants had a fall requiring medical care. In adjusted Cox proportional hazards models, individuals with head injury had 2.01 (95% CI 1.85-2.18) times the risk of falls compared with individuals without head injury. Accounting for the competing risk of mortality, individuals with head injury had 1.69 (95% CI 1.57-1.82) times the risk of falls compared with individuals without head injury. We observed stronger associations among men compared with women (men: hazard ratio [HR] = 2.60, 95% CI 2.25-3.00; women: HR = 1.80, 95% CI 1.63-1.99, p-interaction <0.001). We observed evidence of a dose-response association for head injury number and severity with fall risk (1 injury: HR = 1.68, 95% CI 1.53-1.84; 2+ injuries: HR = 2.37, 95% CI 1.92-2.94 and mild: HR = 1.97, 95% CI 1.78-2.18; moderate/severe/penetrating: HR = 2.50, 95% CI 2.06-3.02). DISCUSSION Among community-dwelling older adults followed over 30 years, head injury was associated with subsequent falls requiring medical care. We observed stronger associations among men and with increasing number and severity of head injuries. Whether older individuals with head injury might benefit from fall prevention measures should be a focus of future research.

Abstract
BACKGROUND Management of orthostatic hypotension (OH) prioritizes prevention of standing hypotension, sometimes at the expense of supine hypertension. It is unclear whether supine hypertension is associated with adverse outcomes relative to standing hypotension. OBJECTIVES To compare the long-term clinical consequences of supine hypertension and standing hypotension among middle-aged adults with and without OH. METHODS The ARIC study (Atherosclerosis Risk in Communities) measured supine and standing blood pressure (BP) in adults aged 45 to 64 years, without neurogenic OH, between 1987 and 1989. We defined OH as a positional drop in systolic BP ≥20 mm Hg or diastolic BP ≥10 mm Hg, supine hypertension as supine BP≥140/≥90 mm Hg, and standing hypotension as standing BP≤105/≤65 mm Hg. Participants were followed for >30 years. We used Cox regression models to examine associations with cardiovascular disease events, all-cause mortality, falls, and syncope. RESULTS Of 12 489 participants (55% female, 26% Black, mean age 54 years, SD 6), 4.4% had OH. Among those without OH (N=11 943), 19% had supine hypertension and 21% had standing hypotension, while among those with OH (N=546), 58% had supine hypertension and 38% had standing hypotension. Associations with outcomes did not differ by OH status (P-interactions >0.25). Supine hypertension was associated with heart failure (hazard ratio, 1.83 [95% CI, 1.68-1.99]), falls (hazard ratio, 1.12 [95% CI, 1.02-1.22]), and all-cause mortality (hazard ratio, 1.45 [95% CI, 1.37-1.54]), while standing hypotension was only significantly associated with mortality (hazard ratio, 1.06 [95% CI, 1.00-1.14]). CONCLUSIONS Supine hypertension was associated with higher risk of adverse events than standing hypotension, regardless of OH status. This challenges conventional OH management, which prioritizes standing hypotension over supine hypertension.

Abstract
BACKGROUND ACC/AHA guidelines caution against the use of antihypertensive therapy in the setting of low standing systolic BP (SBP) < 110 mm Hg due to unclear benefits. METHODS The Atherosclerosis Risk in Communities (ARIC) Study measured supine and standing SBP in adults aged 45-64 years between 1987 and 1989. We used Cox regression to evaluate the associations of low standing SBP (<110 mm Hg) with risk of falls, syncope, coronary heart disease (CHD), and mortality through December 31, 2019. Falls and syncope were ascertained by hospitalization and outpatient claims; CHD events were adjudicated. Associations were examined overall and in strata of hypertension stage, 10-year atherosclerotic cardiovascular disease (ASCVD) risk, age, and sex. RESULTS Among 12,467 adults followed a median of 24 years (mean age at enrollment 54.1 ± 5.8 years, 55% women, 26% Black adults), 3,000 (24%) had a standing SBP < 110 mm Hg. A standing SBP < 110 mm Hg compared to standing SBP ≥ 110 mm Hg was not significantly associated with falls or syncope, and was associated with a lower risk of CHD events and mortality with HRs of 1.02 (95% CI 0.94, 1.11), 1.02 (0.93, 1.11), 0.88 (0.80, 0.97), and 0.91 (0.86, 0.97), respectively. There were no clinically meaningful differences when stratified by hypertension stage, 10-year ASCVD risk, age, and sex. CONCLUSIONS In this community-based population, low standing SBP was common and not significantly associated with falls or syncope, but was associated with a lower risk of CHD and mortality. These findings do not support screening for low standing BP as a risk factor for adverse events.

Abstract
Orthostatic hypotension (OH) is common in Parkinson's Disease (PD). It is intermittent, exacerbated by stressors including meals, medications, and dehydration, and frequently is unrecognized. Although intermittent, assessment is usually by a single "in clinic" BP measurement. This study examines whether 10 home measurements are more sensitive in detecting OH than a single "in clinic" measurement. Participants (44 people with PD and 16 controls) were instructed to measure lying and standing BP at home. BP was measured on five consecutive days upon waking and before bedtime. Symptoms were also assessed using the Movement Disorder Society United Parkinson's Disease Rating Scale and the Non-Motor Questionnaire. While a postural drop in systolic BP (≥20 mmHg) was recorded "in clinic" in thirteen of the forty-four PD participants, a postural drop was found in at least one of the ten home measurements in twenty-eight of the forty-four participants. Morning hypertension and variability in lying systolic BP was more common in these subjects than in those without a postural drop or the controls. A greater number of measurements of lying and standing BP are more likely to reveal orthostatic hypotension, variation in systolic BP, and hypertension than a single office measurement in people with PD.

Abstract
Introduction Patients receiving cancer treatment are at high risk for falls. No current guidelines or standards of care exist for assessment and prevention of outpatient oncology falls. This quality improvement project's purpose was to 1) describe and evaluate outpatient oncology falls data to determine root cause(s), and develop, implement, and evaluate intervention strategies for future policy refinement, and 2) compare fall rates pre/post implementation of a system-wide Ambulatory Fall Risk Bundle. Methods Retrospective data were used to describe and categorize fall incidence for the University of Kansas Cancer Center over 12 months. Further analyses were conducted to describe fall rates per 10,000 kept appointments pre/post implementation of an Ambulatory Fall Risk Bundle protocol. Semi-structured interviews were conducted with medical assistants and nurse managers to evaluate the initiative's impact, staff satisfaction, and recommendations for refinement. Results The initial 12-month assessment yielded 58 patient falls retained for further analyses. Most patients were receiving chemotherapy (46, 79%). Common contributing symptoms included dizziness/ faintness and weakness (25, 43%). Tripping/falling over a hazard (12, 24%) and falls during transfer (10, 5.8%) also were cited. Subsequent analyses of fall rates indicated no change. Recommendations resulting from the qualitative interviews included: orthostatic vital sign protocol implementation, redesign of the electronic medical record fall risk alert, stakeholder involvement in protocol development, staff training, and related patient education strategies, and the procurement of additional assistive devices/equipment. Conclusions System-related policy and culture change, investment in physical and human resource enhancements, and evidence-based protocols are needed to improve outpatient oncology fall rates.

Abstract
OBJECTIVE To determine the association between diuretic use and falls in community-dwelling older women with urinary incontinence (UI). METHODS We conducted an analytic cross-sectional study using patients' electronic medical records. Patients were women with UI, 65 years or older seen at a urogynecology clinic between January 1, 2018 and September 30, 2019. We used logistic regression analysis to explore the associations between falls and diuretic use. RESULTS The study included 108 women, mean age of 75.2 ±7.5 years. Twenty-two (20%) reported one or more falls within the past year and 32 (30%) were diuretic users. Fall prevalence in diuretic users and non-users were 25% (8/32) and 18.4% (14/76), respectively. Diuretic use was not associated with falls (OR = 0.74, 95%CI = 0.22-2.52). Post-hoc analysis revealed inadequate sample size. CONCLUSIONS Diuretics use may not be a risk factor for falls in ambulatory older women with UI. A larger sample will be needed to confirm.

Abstract
BACKGROUND In persons with diabetes, annual screening for peripheral neuropathy (PN) using monofilament testing is the standard of care. However, PN detected by monofilament testing is common in older adults, even in the absence of diabetes. We aimed to assess the association of PN with risk of falls and fractures in older adults. METHODS We included participants in the Atherosclerosis Risk in Communities (ARIC) Study who underwent monofilament testing at visit 6 (2016-2017). Incident falls and fractures were identified based on ICD-9 and ICD-10 codes from active surveillance of all hospitalizations and linkage to Medicare claims. We used Cox models to assess the association of PN with falls and fractures (combined and as separate outcomes) after adjusting for demographics and risk factors for falls. RESULTS There were 3617 ARIC participants (mean age 79.4 [SD 4.7] years, 40.8% male, and 21.4% Black adults), of whom 1242 (34.3%) had PN based on monofilament testing. During a median follow-up of 2.5 years, 371 participants had a documented fall, and 475 participants had a documented fracture. The incidence rate (per 1000 person-years) for falls or fractures for participants with PN versus those without PN was 111.1 versus 74.3 (p < 0.001). The age-, sex-, and race-adjusted 3-year cumulative incidence of incident fall or fracture was significantly higher for participants with PN versus those without PN (26.5% vs. 18.4%, p < 0.001). After adjusting for demographics, PN remained independently associated with falls and fractures (HR 1.48, 95% CI 1.26, 1.74). Results were similar for models including traditional risk factors for falls, when falls and fractures were analyzed as separate outcomes, and after adjustment for competing risk of death. CONCLUSIONS PN, as measured by monofilament testing, is common in older adults and associated with risk of falls and fracture. Screening with monofilament testing may be warranted to identify older adults at high risk for falls.

Abstract
Hip fracture is the most devastating type of osteoporosis-related fracture, and is a major worldwide public health problem with a high socioeconomic burden, morbidity rate, and mortality rate. Thus, it is crucial to uncover the risk factors and protective factors to create a hip fracture prevention strategy. In addition to a briefly review of some well accepted risk and protective factors of hip fracture, this review mainly summarized the recent advances in the identification of emerging risk or protective factors for hip fracture, in terms of regional differences in medical services, diseases, drugs, mechanical load, neuromuscular mass, genes, blood types, cultural differences. This review provides a comprehensive review of the associated factors and effective prevention measures for hip fracture, and discusses issues that need further investigation. These issues include the determination of the influencing mechanism of risk factors triggering hip fracture and their interlinked correlation with other factors, as well as the confirmation or correction of emerging factors associated with hip fracture, particularly those that are still controversial. These recent findings will aid in optimizing the strategy for preventing hip fracture.

Abstract
Supine hypertension-orthostatic hypotension disease poses a management challenge to clinicians. Data on short term outcomes of patients with orthostatic hypotension (OH) who are hospitalized with hypertensive (HTN) crises is lacking. The Nationwide Readmission Database 2016-2019 was queried for all hospitalizations of HTN crises. Hospitalizations were stratified according to whether OH was present or not. We employed propensity score to match hospitalizations for patients with OH to those without, at 1:1 ratio. Outcomes evaluated were 30-days readmission with HTN crises or falls, as well as hospital outcomes of in-hospital mortality, acute kidney injury, acute congestive heart failure, acute coronary syndrome, type 2 myocardial infarction, aortic dissection, stroke, length of stay (LOS), discharge to nursing home and hospitalization costs. We included a total of 9451 hospitalization (4735 in the OH group vs 4716 in the control group). OH group was more likely to be readmitted with falls (Odds ratio [OR]:3.27, P < 0.01) but not with HTN crises (P = 0.05). Both groups had similar likelihood of developing acute kidney injury (P = 0.08), stroke/transient ischemic attack (P = 0.52), and aortic dissection (P = 0.66). Alternatively, OH group were less likely to develop acute heart failure (OR:0.54, P < 0.01) or acute coronary syndrome (OR:0.39, P < 0.01) in the setting of HTN crises than non-OH group. OH group were more likely to have longer LOS and have higher hospitalization costs. Patients with OH who are admitted with HTN crises tend to have similar or lower HTN-related complications to non-OH group while having higher likelihood of readmission with falls, LOS and hospitalization costs. Further studies are needed to confirm such findings.

Abstract
Falls among the older adults (64+ years old [YO]) are considered public health issues. However, fall prevention in middle adulthood (age 45-64) has received less attention. We studied the associations between the number of falls and fall-related injuries and indicators for socio-demographics, chronic diseases, and difficulties in conducting activities in two age groups, 45-64 YO and 64+. In this secondary data analysis, we used the Behavioral Risk Factor Surveillance System (BRFSS) 2018 data. The study showed respondents in the 45-64 YO have higher average falls and fall-related injuries than those 64+ (P < .001). Variables that link to more falls and fall-related injuries in 64+ correspond to more falls and fall-related injuries in 45-64 YO. The finding indicates that the odds of falls and fall-related injuries are comparable across age groups when considering demographic characteristics. However, odds of falling in the presence of arthritis and asthma are higher for respondents in 45-64 YO than the 64+ YO. The risk of falls and fall-related injuries are not specific to older adults. Factors that matter to the number of falls and fall-related injuries in the older adults also count in the younger age group. Nurses are asked to validate available fall assessment tools for adults 45-64 years old and evaluate all clients over 45 for fall risk.

Quinn C, Monaghan A, Foran T, Kenny RA, Gormley J. A Review of Heart Rate and Blood Pressure Responses to Active Standing in Healthy Adults. Curr Aging Sci 2022; 15:198-208. [PMID: 35440341 DOI: 10.2174/1874609815666220419102648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 02/16/2022] [Accepted: 03/06/2022] [Indexed: 06/14/2023]
Abstract
OBJECTIVES This review outlines the normal heart rate and blood pressure response to active standing, the physiological mechanisms governing these, and the effect of ageing on the responses. METHODS A literature search was conducted to identify articles investigating the normal heart rate and/or blood pressure response to standing. RESULTS Heart rate when standing increases and then decreases and recovers to baseline. Blood pressure responses are inverse. Skeletal muscle contraction and the baroreceptor reflex drive this. With ageing, heart rate response attenuates and the initial blood pressure response increases. DISCUSSION Normal heart rate and blood pressure responses are attributed to the baroreceptor reflex and skeletal muscle contraction. Decreased muscle strength and baroreceptor sensitivity are associated with ageing, suggesting a possible benefit in improving skeletal muscle strength to maintain an efficient response. Understanding these responses and their variation with ageing is clinically relevant and may be beneficial in improving rehabilitation outcomes.

Comprehensive telemedicine solution for remote monitoring of Parkinson's disease patients with orthostatic hypotension during COVID-19 pandemic. Neurol Sci 2022; 43:3479-3487. [PMID: 35301614 PMCID: PMC8930064 DOI: 10.1007/s10072-022-05972-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 02/21/2022] [Indexed: 12/04/2022]
Abstract
OBJECTIVE Orthostatic hypotension (OH) represents a frequent but under-recognized phenomenon in Parkinson's disease (PD). During COVID-19 pandemic, Information and Communication Technologies (ICT) have become pivotal in the management of chronic diseases like PD, not only to assess motor impairment, but also for vital signs monitoring. This pilot study aimed to propose a real-time remote home-monitoring system and protocol for PD patients with OH. METHODS Vital parameters were acquired by wireless devices and transmitted to an ICT platform, providing data and smart notifications to the healthcare provider through an interactive web portal. Eight patients with idiopathic PD and OH underwent 5-day monitoring. Data about OH episodes, therapeutic interventions, impact on daily activities, and patient satisfaction were collected and analyzed. RESULTS The proposed solution allowed the identification of 65 OH episodes and subsequent medical interventions. Thirty-five episodes were asymptomatic, especially in the postprandial and in the afternoon recordings. Systolic-blood-pressure (SBP) and diastolic-blood-pressure (DBP) were significantly lower in symptomatic episodes, while the pressure drops resulted significantly higher in presence of symptoms. High usability and patient satisfaction scores were observed. CONCLUSION The proposed home-monitoring system and protocol have proved to provide useful information and to allow prompt interventions in the management of PD patients with OH during COVID-19 pandemic.

Comparison of supine and seated orthostatic hypotension assessments and their association with falls and orthostatic symptoms. J Am Geriatr Soc 2022; 70:2310-2319. [PMID: 35451096 PMCID: PMC9378443 DOI: 10.1111/jgs.17804] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 03/07/2022] [Accepted: 03/16/2022] [Indexed: 12/27/2022]
Abstract
BACKGROUND Orthostatic hypotension (OH) based on a change from seated-to-standing blood pressure (BP) is often used interchangeably with supine-to-standing BP. METHODS The Study to Understand Fall Reduction and Vitamin D in You (STURDY) was a randomized trial of vitamin D3 supplementation and fall in adults aged ≥70 years at high risk of falls. OH was defined as a drop in systolic or diastolic BP of at least 20 or 10 mmHg, measured at pre-randomization, 3-, 12-, and 24-month visits with each of 2 protocols: seated-to-standing and supine-to-standing. Participants were asked about orthostatic symptoms, and falls were ascertained via daily fall calendar, ad hoc reporting, and scheduled interviews. RESULTS Among 534 participants with 993 paired supine and seated assessments (mean age 76 ± 5 years, 42% women, 18% Black), mean baseline BP was 130 ± 19/68 ± 11 mmHg; 62% had a history of high BP or hypertension. Mean BP increased 3.5 (SE, 0.4)/2.6 (SE, 0.2) mmHg from sitting to standing, but decreased with supine to standing (mean change: -3.7 [SE, 0.5]/-0.8 [SE, 0.3] mmHg; P-value < 0.001). OH was detected in 2.1% (SE, 0.5) of seated versus 15.0% (SE, 1.4) of supine assessments (P < 0.001). While supine and seated OH were not associated with falls (HR: 1.55 [0.95, 2.52] vs 0.69 [0.30, 1.58]), supine systolic OH was associated with higher fall risk (HR: 1.77 [1.02, 3.05]). Supine OH was associated with self-reported fainting, blacking out, seeing spots and room spinning in the prior month (P-values < 0.03), while sitting OH was not associated with any symptoms (P-values ≥ 0.40). CONCLUSION Supine OH was more frequent, associated with orthostatic symptoms, and potentially more predictive of falls than seated OH.

Abstract
Introduction Falls are a significant cause of morbidity and mortality in older adults. Orthostatic hypotension (OH) is very common in this cohort of patients and is a significant risk for falls and associated injuries. We present the case of an 89-year-old female who fell at home, witnessed by her husband. OH was identified during the clinical assessment and considered to be the predominant contributing factor, although the clinical presentation was not associated with classical symptoms. Case presentation The patient lost balance while turning away from the kitchen sink; she noted some instability due to a complaint of generalised weakness in both of her legs. No acute medical illness or traumatic injury was identified. A comprehensive history was obtained that identified multiple intrinsic and extrinsic risk factors for falling. The cardiovascular examination was unremarkable except for OH, with a pronounced reduction in systolic blood pressure of 34 mmHg at the three-minute interval and which reproduced some generalised weaknesses in the patient's legs and slight instability. Although classical OH symptoms were not identified, this was considered to be the predominant factor contributing to the fall. A series of recommendations was made to primary and community-based care teams based upon a rapid holistic review; this included a recommendation to review the patient's dual antihypertensive therapy. Conclusion It is widely known that OH is a significant risk factor for falls, but asymptomatic or atypical presentations can make diagnosis challenging. Using the correct technique to measure a lying and standing blood pressure, as defined by the Royal College of Physicians, is crucial for accurate diagnosis and subsequent management. Ambulance clinicians are ideally placed to undertake this quick and non-invasive assessment to identify OH in patients that have fallen.

Abstract
Falls are prominent health issues among older adults. Among hypertensive older adults, falls may have a detrimental effect on their health and wellbeing. The purpose of this study is to determine the prevalence of falls among hypertensive older adults and to identify the associated factors that contribute to their falls. This was a cross-sectional study conducted among two hundred and sixty-nine hypertensive older adults who were selected via systematic random sampling in two primary health clinics in Kuala Terengganu, Malaysia. Data on their socio-demographic details, their history of falls, medication history and clinical characteristics were collected. Balance and gait were assessed using the Performance Oriented Mobility Assessment (POMA). It was found that 32.2% of participants reported falls within a year. Polypharmacy (adjusted OR 2.513, 95% CI 1.339, 4.718) and diuretics (adjusted OR 2.803, 95% CI 1.418, 5.544) were associated with an increased risk of falls. Meanwhile, a higher POMA score (adjusted OR 0.940, 95% CI 0.886, 0.996) and the number of antihypertensives (adjusted OR 0.473, 95% CI 0.319, 0.700) were associated with a low incidence of falling among hypertensive older adults. Falls are common among hypertensive older adults. Older adults who are taking diuretics and have a polypharmacy treatment plan have a higher incidence of falls. However, older adults taking a higher number of anti-hypertensive medications specifically were not associated with an increased prevalence of falls.

Abstract
Orthostatic hypotension is common and dangerous; it has neurogenic and nonneurogenic causes. We present the case of a 40-year-old man with severe neurogenic hypotension, caused by young-onset multiple system atrophy. In patients presenting with neurogenic orthostatic hypotension, underlying neurodegenerative diseases should always be considered. (Level of Difficulty: Advanced.)

Abstract
OBJECTIVE assess how many patients with low ambulatory diastolic blood pressure (DBP) are not identified when relying on office DBP alone, and thus have 'masked diastolic hypotension'. DESIGN cross-sectional, retrospective cohort study. SETTING academic hospital. SUBJECTS 848 patients treated for hypertension who received ambulatory blood pressure monitoring (ABPM). METHODS cut-off value between on- and off-target systolic blood pressure (SBP): 140 mmHg. Cut-off for low office and/or ambulatory DBP: DBP ≤ 70 mmHg. 'Masked diastolic hypotension' was defined as office DBP > 70 mmHg and mean ambulatory DBP ≤ 70 mmHg. RESULTS mean age of the sample was 60 ± 13 years, 50% was female, 37% had diabetes, 42% preexisting cardiovascular disease (CVD), mean office blood pressure (BP) was 134/79 mmHg. In all patients (n = 848), low office DBP was present in n = 84(10%), while n = 183(22%) had low ambulatory DBP. In all patients with normal-to-high office DBP (n = 764), n = 122(16%) had 'masked diastolic hypotension'. In this group, ambulatory DBP was 14-19 mmHg lower than office DBP. Patients with low ambulatory DBP were older, had more (cardiovascular) comorbidities, and used more (antihypertensive) drugs. Antihypertensive drugs were lowered or discontinued in 30% of all patients with 'masked diastolic hypotension' due to side effects. CONCLUSIONS 'masked diastolic hypotension' is common among patients treated for hypertension, particularly in older patients with CVD (e.g. coronary artery disease, diabetes), patient groups in which the European Society of Cardiology/Hypertension guideline advises to prevent low DBP. Although it remains to be examined at which BP levels the harms of low DBP outweigh the benefits of lowering SBP, our observations are aimed to increase awareness among physicians.

Older Adults' Drop in Cerebral Oxygenation on Standing Correlates With Postural Instability and May Improve With Sitting Prior to Standing. J Gerontol A Biol Sci Med Sci 2021; 76:1124-1133.

Abstract
BACKGROUND Impaired blood pressure (BP) recovery with orthostatic hypotension on standing occurs in 20% of older adults. Low BP is associated with low cerebral blood flow but mechanistic links to postural instability and falls are not established. We investigated whether posture-related reductions in cerebral tissue oxygenation (tSO2) in older adults impaired stability upon standing, if a brief sit before standing improved tSO2 and stability, and if Low-tSO2 predicted future falls. METHOD Seventy-seven older adults (87 ± 7 years) completed (i) supine-stand, (ii) supine-sit-stand, and (iii) sit-stand transitions with continuous measurements of tSO2 (near-infrared spectroscopy). Total path length (TPL) of the center of pressure sway quantified stability. K-cluster analysis grouped participants into High-tSO2 (n = 62) and Low-tSO2 (n = 15). Fall history was followed up for 6 months. RESULTS Change in tSO2 during supine-stand was associated with increased TPL (R = -.356, p = .001). When separated into groups and across all transitions, the Low-tSO2 group had significantly lower tSO2 (all p < .01) and poorer postural stability (p < .04) through 3 minutes of standing compared to the High-tSO2 group. There were no effects of transition type on tSO2 or TPL for the High-tSO2 group, but a 10-second sitting pause improved tSO2 and enhanced postural stability in the Low-tSO2 group (all p < .05). During 6-month follow-up, the Low-tSO2 group had a trend (p < .1) for increased fall risk. CONCLUSIONS This is the first study to show an association between posture-related cerebral hypoperfusion and quantitatively assessed instability. Importantly, we found differences among older adults suggesting those with lower tSO2 and greater instability might be at increased risk of a future fall.

Abstract
Orthostatic hypotension (OH) is very common in older people and is encountered daily in emergency departments and medical admissions units. It is associated with a higher risk of falls, fractures, dementia and death, so prompt recognition and treatment are essential. In this review article, we describe the physiology of standing (orthostasis) and the pathophysiology of orthostatic hypotension. We focus particularly on aspects pertinent to older people. We review the evidence and consensus management guidelines for all aspects of management. We also tackle the challenge of concomitant orthostatic hypotension and supine hypertension, providing a treatment overview as well as practical suggestions for management. In summary, orthostatic hypotension (and associated supine hypertension) are common, dangerous and disabling, but adherence to simple structures management strategies can result in major improvements.

Abstract
Background: Background: Management of schizophrenia using psychopharmaceuticals requires a long-term treatment. The use of antipsychotic drugs can cause the occurrence of orthostatic hypotension, which leads to the risk of falling in patients. The aim of this study is to determine the effect of the use of antipsychotic drugs and orthostatic hypotension on the risk of falling in schizophrenic patients. Design and Methods: This study used a descriptive design with 53 respondents. Data were analyzed using the contingency coefficient correlation and Spearman Rank test methods. Results: The results of the first study showed no positive effect between the use of antipsychotics on orthostatic hypotension in schizophrenic patients. In addition, a contingency coefficient correlation (C) of 0.199 and p-value of 0.335 (p>0.05) was obtained. The results of the second study showed that there was a significant positive effect between orthostatic hypotension on the risk of falling in schizophrenic patients with a value of r = 0.483 and a pvalue of 0.000 (p0.001). Conclusion: It was suggested that the development of this study’s result is needed for further research in dealing with the incidence of orthostatic hypotension in order to prevent or reduce the risk of falling in schizophrenic patients. Significance for public health Nurses should know how to measure blood pressure in order to determine the incidence of orthostatic hypotension. Nurses have an important role to play in preventing the risk of falling in patients. This is used as an indicator in achieving the quality of patient safety and in determining the quality of services in the hospital. This study describes the effect of the use of antipsychotic drugs and orthostatic hypotension on the risk of falls in schizophrenic patients in Dr. H. Marzoeki Mahdi Hospital Bogor.

Exposures Orthostatic hypotension (decline in systolic blood pressure [BP] > 20 mm Hg) and orthostatic hypertension (increase in systolic BP > 20 mm Hg) from seated to standing position. Outcomes Cardiovascular and kidney outcomes and mortality. Analytical Approach Logistic regression was used to determine factors associated with orthostatic hypo- and hypertension; Cox regression was used to examine associations with clinical outcomes. Results Mean age of study population (n = 3,873) was 58.1 ± 11.0 years. There was a wide distribution of change in systolic BP from seated to standing (from −73.3 to +60.0 mm Hg); 180 participants (4.6%) had orthostatic hypotension and 81 (2.1%) had orthostatic hypertension. Diabetes, reduced body mass index, and β-blocker use were independently associated with orthostatic hypotension. Black race and higher body mass index were independently associated with orthostatic hypertension. After a median follow-up of 7.9 years, orthostatic hypotension was independently associated with high risk for cardiovascular (HR, 1.12; 95% CI, 1.03-1.21) but not kidney outcomes or mortality. Orthostatic hypertension was independently associated with high risk for kidney (HR, 1.51; 96% CI, 1.14-1.97) but not cardiovascular outcomes or mortality. Limitations Orthostatic change in BP was ascertained at a single visit. Conclusions Orthostatic hypotension was independently associated with higher risk for cardiovascular outcomes, whereas orthostatic hypertension was associated with higher risk for kidney outcomes. These findings highlight the importance of orthostatic BP measurement in practice and the need for future investigation to understand the mechanisms and potential interventions to minimize the risk associated with orthostatic changes in BP.

Abstract
Falls are a leading cause of unintentional injuries and can result in devastating disabilities and fatalities when left undetected and not treated in time. Current detection methods have one or more of the following problems: frequent battery replacements, wearer discomfort, high costs, complicated setup, furniture occlusion, and intensive computation. In fact, all non-wearable methods fail to detect falls beyond ten meters. Here, we design a house-wide fall detection system capable of detecting stumbling, slipping, fainting, and various other types of falls at 60 m and beyond, including through transparent glasses, screens, and rain. By analyzing the fall pattern using machine learning and crafted rules via a local, low-cost single-board computer, true falls can be differentiated from daily activities and monitored through conventionally available surveillance systems. Either a multi-camera setup in one room or single cameras installed at high altitudes can avoid occlusion. This system's flexibility enables a wide-coverage set-up, ensuring safety in senior homes, rehab centers, and nursing facilities. It can also be configured into high-precision and high-recall application to capture every single fall in high-risk zones.

Abstract
PURPOSE Orthostatic hypotension, leading to cerebral hypoperfusion, can result in postural instability and falls in older adults. We determined the efficacy of a novel, intermittent pneumatic compression system, applying pressure around the lower legs, as a countermeasure against orthostatic stress in older adults. METHODS Data were collected from 13 adults (4 male) over 65 years of age. Non-invasive ultrasound measured middle cerebral artery blood velocity (MCAv) and finger photoplethysmography measured mean arterial blood pressure (MAP). Intermittent lower leg compression was applied in a peristaltic manner in the local diastolic phase of each cardiac cycle to optimize venous return during 1-min of seated rest and during a sit-to-stand transition to 1-min of quiet standing with compression initiated 15 s before transition. RESULTS During seated rest, compression resulted in a 4.5 ± 6.5 mmHg increase in MAP, and 2.3 ± 2.1 cm/s increase in MCAv (p < 0.05). MAP and MCAv increased during the 15 s of applied compression before the posture transition (2.3 ± 7.2 mmHg and 2.1 ± 4.0 cm/s, respectively, p < 0.05) with main effects for both variables confirming continued benefit during the transition and quiet stand periods. CONCLUSIONS Application of carefully timed, intermittent compression to the lower legs of older adults increased MAP and MCAv during seated rest and maintained an elevated MAP and MCAv during a transition to standing posture. Future research could assess the benefits of this technology for persons at risk for orthostatic hypotension on standing and while walking in an effort to reduce injurious, unexplained falls in older adults.

Abstract
BACKGROUND Postural hypotension (PH), the reduction in blood pressure when rising from sitting or lying 0to standing, is a risk factor for falls, cognitive decline and mortality. However, it is not often tested for in primary care. PH prevalence varies according to definition, population, care setting and measurement method. The aim of this study was to determine the prevalence of PH across different care settings and disease subgroups. METHODS Systematic review, meta-analyses and meta-regression. We searched Medline and Embase to October 2019 for studies based in primary, community or institutional care settings reporting PH prevalence. Data and study level demographics were extracted independently by two reviewers. Pooled estimates for mean PH prevalence were compared between care settings and disease subgroups using random effects meta-analyses. Predictors of PH were explored using meta-regression. Quality assessment was undertaken using an adapted Newcastle-Ottawa Scale. RESULTS One thousand eight hundred sixteen studies were identified; 61 contributed to analyses. Pooled prevalences for PH using the consensus definition were 17% (95% CI, 14-20%; I2 = 99%) for 34 community cohorts, 19% (15-25%; I2 = 98%) for 23 primary care cohorts and 31% (15-50%; I2 = 0%) for 3 residential care or nursing homes cohorts (P = 0.16 between groups). By condition, prevalences were 20% (16-23%; I2 = 98%) with hypertension (20 cohorts), 21% (16-26%; I2 = 92%) with diabetes (4 cohorts), 25% (18-33%; I2 = 88%) with Parkinson's disease (7 cohorts) and 29% (25-33%, I2 = 0%) with dementia (3 cohorts), compared to 14% (12-17%, I2 = 99%) without these conditions (P < 0.01 between groups). Multivariable meta-regression modelling identified increasing age and diabetes as predictors of PH (P < 0.01, P = 0.13, respectively; R2 = 36%). PH prevalence was not affected by blood pressure measurement device (P = 0.65) or sitting or supine resting position (P = 0.24), however, when the definition of PH did not fulfil the consensus description, but fell within its parameters, prevalence was underestimated (P = 0.01) irrespective of study quality (P = 0.04). CONCLUSIONS PH prevalence in populations relevant to primary care is substantial and the definition of PH used is important. Our findings emphasise the importance of considering checking for PH, particularly in vulnerable populations, to enable interventions to manage it. These data should contribute to future guidelines relevant to the detection and treatment of PH. PROSPERO CRD42017075423.

Abstract
OBJECTIVE Hypoglycemia has been postulated to contribute to falls risk in older adults with type 2 diabetes. However, few studies have prospectively examined the association between severe hypoglycemia and falls, both important causes of morbidity and mortality. RESEARCH DESIGN AND METHODS We conducted a prospective cohort analysis of participants from the Atherosclerosis Risk in Communities (ARIC) study with diagnosed diabetes at visit 4 (1996-1998). Episodes of severe hypoglycemia requiring medical treatment were identified using ICD-9 codes from hospitalizations, emergency department visits, and ambulance calls; total falls were identified from medical claims using E-codes from 1996 to 2013. Secondary analyses examined hospitalized falls and falls with fracture. We calculated incidence rates and used Cox regression models to evaluate the independent association of severe hypoglycemia with falls occurring after visit 4 through 2013. RESULTS Among 1,162 participants with diabetes, 149 ever had a severe hypoglycemic event before baseline or during the median of 13.1 years of follow-up. The crude incidence rate of falls among persons without severe hypoglycemia was 2.17 per 100 person-years (PY) (95% CI 1.93-2.44) compared with 8.81 per 100 PY (6.73-11.53) with severe hypoglycemia. After adjustment, severe hypoglycemia was associated with a more than twofold higher risk of falls (hazard ratio 2.23, 95% CI 1.61-3.07). Associations were consistent in subgroups defined by age, sex, race, BMI, duration of diabetes, or functional difficulty. CONCLUSIONS Severe hypoglycemia was associated with a substantially higher risk of falls in this community-based population of adults with diabetes. Fall risk should be considered when individualizing glycemic treatment in older adults. Assessing hypoglycemia history and future hypoglycemia risk could also improve multifactorial fall prevention interventions for older adults with diabetes.

Abstract
Neurogenic orthostatic hypotension (nOH) is a subtype of orthostatic hypotension in which patients have impaired regulation of standing blood pressure due to autonomic dysfunction. Several primary and secondary causes of this disease exist. Patients may present with an array of symptoms making diagnosis difficult. This review article addresses the epidemiology, pathophysiology, causes, clinical features, and management of nOH. We highlight various pharmacological and non-pharmacological approaches to treatment, and review the recent guidelines and our approach to nOH.

Abstract
Heart failure (HF)is a condition at high risk for orthostatic hypotension (OH)given the large proportion of patients at an advanced age and high burden of comorbidities contributing to OH, as well as a high prevalence of medications with neurovascular and volume modulating properties. Early identification of OH in HF seems to be crucial as OH can have an impact on patient symptoms, activity level and independence, be a marker of specific pathophysiological changes or be an indicator of need for personalized treatment. OH might contribute significantly to bad enough prognosis in HF, as, besides a risk of falls and cognitive decline, it was found to be associated with cardiovascular morbidity and mortality. In this review, we aimed to incentivize the routine use of orthostatic testing in HF, as well as stimulate future research in this field, which could lead to significant advances in the treatment and outcomes.

Abstract
OBJECTIVE To test the hypothesis that orthostatic hypotension (OH) might cause cerebral hypoperfusion and injury, we examined the longitudinal relationship between OH or orthostatic symptoms and incident neurologic outcomes in a community population of older adults. METHODS Cardiovascular Health Study participants (≥65 years) without dementia or stroke had blood pressure (BP) measured after lying down for 20 minutes and after standing 3 for minutes. Participants reported dizziness immediately upon standing and any dizziness in the past 2 weeks. OH was defined as a drop in standing systolic/diastolic BP ≥20/≥10 mm Hg. We determined the association between OH or dizziness with (1) MRI brain findings (ventricular size, white matter hyperintensities, brain infarcts) using linear or logistic regression, (2) cognitive function (baseline and over time) using generalized estimating equations, and (3) prospective adjudicated events (dementia, stroke, death) using Cox models. Models were adjusted for demographic characteristics and OH risk factors. We used multiple imputation to account for missing OH or dizziness (n = 534). RESULTS Prior to imputation, there were 5,007 participants (mean age 72.7 ± 5.5 years, 57.6% women, 10.9% Black, 16% with OH). OH was modestly associated with death (hazard ratio [HR] 1.11; 95% confidence interval 1.02-1.20), but not MRI findings, cognition, dementia, or stroke. In contrast, dizziness upon standing was associated with lower baseline cognition (β = -1.20; -1.94 to -0.47), incident dementia (HR 1.32; 1.04-1.62), incident stroke (HR 1.22; 1.06-1.41), and death (HR 1.13; 1.06-1.21). Similarly, dizziness over the past 2 weeks was associated with higher white matter grade (β = 0.16; 0.03-0.30), brain infarcts (OR 1.31; 1.06-1.63), lower baseline cognition (β = -1.18; -2.01 to -0.34), and death (HR 1.13; 1.04-1.22). CONCLUSIONS Dizziness was more consistently associated with neurologic outcomes than OH 3 minutes after standing. Delayed OH assessments may miss pathologic information related to cerebral injury.

Performance of High-Sensitivity Cardiac Troponin Assays to Reflect Comorbidity Burden and Improve Mortality Risk Stratification in Older Adults With Diabetes. Diabetes Care 2020; 43:1200-1208. [PMID: 32161049 PMCID: PMC7245347 DOI: 10.2337/dc19-2043] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Accepted: 02/11/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE Incorporation of comorbidity burden to inform diabetes management in older adults remains challenging. High-sensitivity cardiac troponins are objective, quantifiable biomarkers that may improve risk monitoring in older adults. We assessed the associations of elevations in high-sensitivity cardiac troponin I (hs-cTnI) and T (hs-cTnT) with comorbidities and improvements in mortality risk stratification. RESEARCH DESIGN AND METHODS We used logistic regression to examine associations of comorbidities with elevations in either troponin (≥85th percentile) among 1,835 participants in the Atherosclerosis Risk in Communities (ARIC) Study with diabetes (ages 67-89 years, 43% male, 31% black) at visit 5 (2011-2013). We used Cox models to compare associations of high cardiac troponins with mortality across comorbidity levels. RESULTS Elevations in either troponin (≥9.4 ng/L for hs-cTnI, ≥25 ng/L for hs-cTnT) were associated with prevalent coronary heart disease, heart failure, chronic kidney disease, pulmonary disease, hypoglycemia, hypertension, dementia, and frailty. Over a median follow-up of 6.2 years (418 deaths), both high hs-cTnI and high hs-cTnT further stratified mortality risk beyond comorbidity levels; those with a high hs-cTnI or hs-cTnT and high comorbidity were at highest mortality risk. Even among those with low comorbidity, a high hs-cTnI (hazard ratio 3.0 [95% CI 1.7, 5.4]) or hs-cTnT (hazard ratio 3.3 [95% CI 1.8, 6.2]) was associated with elevated mortality. CONCLUSIONS Many comorbidities were reflected by both hs-cTnI and hs-cTnT; elevations in either of the troponins were associated with higher mortality risk beyond comorbidity burden. High-sensitivity cardiac troponins may identify older adults at high mortality risk and be useful in guiding clinical care of older adults with diabetes.

Abstract
Failure to recognize symptoms of orthostatic hypotension (OH) may result in falls, syncope, and injuries. The relationship between orthostatic changes in blood pressure and symptom occurrence and severity is not known. The goal of the present study was to define the relationship between the occurrence and severity of the symptoms of orthostatic hypotension (OH) and (1) the upright systolic blood pressure (SBP) and (2) the fall in SBP after tilting in patients with OH. We prospectively studied 89 patients with OH. Reported BP values include the lowest BP in the first 3 minutes of tilt and the change in blood pressure during tilt. Subjects were queried about symptoms of orthostatic intolerance while supine and during the first 3 minutes of tilt testing using Question 1 of the Orthostatic Hypotension Questionnaire. Mean tilted SBP was 101.6±26.1 mm Hg and mean SBP fall 47.9±18.1 mm Hg. Mean symptom scores when upright were: light-headedness (2.3/10±2.7), dizziness (1.6/10±2.5), and impending blackout (0.8/10±1.9). The majority of patients were asymptomatic or mildly symptomatic and no discrete cutoff for symptoms was observed. The magnitude of the SBP fall (r=-0.07, P=NS) and the lowest upright SBP (r=0.08, P=NS) did not correlate with any reported symptom. These results suggest a poor relationship between the magnitude of the orthostatic BP fall, the upright orthostatic BP, and symptoms. Many patients are asymptomatic despite substantial SBP falls and low orthostatic blood pressures. These findings have implications for clinical care of patients with OH and clinical trials to treat patients with OH.

Abstract
BACKGROUND/OBJECTIVES Little work to date has examined the relationship between gait performance and blood pressure (BP) recovery after standing in later life. The aim of this study is to clarify the association of orthostatic BP with spatiotemporal gait parameters in a large cohort of older people. DESIGN Cross-sectional study using multilevel linear regression to ascertain the difference in orthostatic BP patterns across tertiles of gait speed, and linear regression to analyze the association of orthostatic hypotension 30 seconds after standing (OH-30) with specific gait characteristics. SETTING The Irish Longitudinal Study on Ageing. PARTICIPANTS A total of 4311 community-dwelling adults, aged 50 years or older (mean age = 62.2 years; 54% female), one fifth (n = 791) of whom had OH-30. MEASUREMENTS Continuous orthostatic BP was measured during active stand. OH-30 was defined as a drop in systolic BP of 20 mm Hg or more or drop in diastolic BP of 10 mm Hg or more at 30 seconds. Spatiotemporal gait was assessed using the GAITRite system, reporting gait speed, step length, step width, and double support time in both single and dual (cognitive task) conditions. RESULTS OH-30 was associated with slower gait speed (β = -3.01; 95% confidence interval [CI] = -4.46 to -1.56) and shorter step length (β = -.73; 95% CI = -1.29 to -.16) in fully adjusted models during single task walking. Similar findings were observed in dual task conditions, in addition to increased double support phase (β = .45; 95% CI = .02-.88). Multilevel models demonstrated that participants in the slowest tertile for gait speed had a significantly larger drop in systolic BP poststanding compared to those with faster gait speeds in single and dual task conditions. CONCLUSIONS This study demonstrates that slower recovery of BP after standing is independently associated with poorer gait performance in community-dwelling older adults. Given the adverse outcomes independently associated with OH and gait problems in later life, increasing awareness that they commonly coexist is important, particularly as both are potentially modifiable.

Abstract
Orthostatic hypotension (OH) is frequently observed with hypertension treatment, but its contribution to adverse outcomes is unknown. The SPRINT (Systolic Blood Pressure Intervention Trial) was a randomized trial of adults, age ≥50 years at high risk for cardiovascular disease with a seated systolic blood pressure (BP) of 130 to 180 mm Hg and a standing systolic BP ≥110 mm Hg. Participants were randomized to a systolic BP treatment goal of either <120 or <140 mm Hg. OH was defined as a drop in systolic BP ≥20 or diastolic BP ≥10 mm Hg 1 minute after standing from a seated position. We used Cox models to examine the association of OH with cardiovascular disease or adverse study events by randomized BP goal. During the follow-up period (median 3years), there were 1170 (5.7%) instances of OH among those assigned a standard BP goal and 1057 (5.0%) among those assigned the intensive BP goal. OH was not associated with higher risk of cardiovascular disease events (primary outcome: hazard ratio 1.06 [95% CI, 0.78-1.44]). Moreover, OH was not associated with syncope, electrolyte abnormalities, injurious falls, or acute renal failure. OH was associated with hypotension-related hospitalizations or emergency department visits (hazard ratio, 1.77 [95% CI, 1.11-2.82]) and bradycardia (hazard ratio, 1.94 [95% CI, 1.19-3.15]), but these associations did not differ by BP treatment goal. OH was not associated with a higher risk of cardiovascular disease events, and BP treatment goal had no effect on OH's association with hypotension and bradycardia. Symptomless OH during hypertension treatment should not be viewed as a reason to down-titrate therapy even in the setting of a lower BP goal.

Abstract
We tested the hypothesis that transient deficits in cerebral blood flow are associated with postural sway. In 19 young, healthy adults, we examined the association between the drop in cerebral blood flow during supine-to-stand transitions, indexed by transcranial Doppler ultrasound [middle cerebral artery blood velocity at diastole (MCAdv)] and near-infrared spectroscopy [tissue saturation index (TSI)] and the center of pressure displacement while standing. Participants performed transitions under three conditions aimed at progressively increasing the drop in MCAdv, in a randomized order: 1) a control transition (Con); 2) a transition that coincided with deflation of bilateral thigh cuffs; and 3) a transition that coincided with both thigh-cuff deflation and 90 s of prior hyperventilation (HTC). The deficit in diastolic blood velocity (MCAdv deficit) was quantified as the difference between MCAdv and its preceding baseline value, summed over 10 s, beginning at the MCAdv nadir. Compared with Con, HTC led to greater drops in MCAdv (P = 0.003) and TSI (P < 0.001) at nadir. The MCAdv deficit was positively associated with the center of pressure displacement vector-average using repeated-measures correlation (repeated-measures correlation coefficient = 0.56, P < 0.001). An a posteriori analysis identified a sub-group of participants that showed an exaggerated increase in MCAdv deficit and greater postural instability in both the anterior-posterior (P = 0.002) and medial-lateral (P = 0.021) directions in response to the interventions. These findings support the theory that individuals who experience greater initial cerebral hypoperfusion on standing may be at a greater risk for falls.NEW & NOTEWORTHY Dizziness and risk for falls after standing might link directly to reduced delivery of oxygen to the brain. By introducing challenges that increased the drop in brain blood flow in healthy young adults, we have shown for the first time a direct link to greater postural instability. These results point to a need to measure cerebral blood flow and/or oxygenation after postural transitions in populations, such as older adults, to assist in fall risk assessment.

Abstract
Spinal cord injury (SCI) often results in the devastating loss of motor, sensory, and autonomic function. After SCI, the interruption of descending sympathoexcitatory pathways disrupts supraspinal control of blood pressure (BP). A common clinical consequence of cardiovascular dysfunction after SCI is orthostatic hypotension (OH), a debilitating condition characterized by rapid profound decreases in BP when assuming an upright posture. OH can result in a diverse array of insidious and pernicious health consequences. Acute effects of OH include decreased cardiac filling, cerebral hypoperfusion, and associated presyncopal symptoms such as lightheadedness and dizziness. Over the long term, repetitive exposure to OH is associated with a drastically increased prevalence of heart attack and stroke, which are leading causes of death in those with SCI. Current recommendations for managing BP after SCI primarily include pharmacologic interventions with prolonged time to effect. Because most episodes of OH occur in less than 3 minutes, this delay in action often renders most pharmacologic interventions ineffective. New innovative technologies such as epidural and transcutaneous spinal cord stimulation are being explored to solve this problem. It might be possible to electrically stimulate sympathetic circuitry caudal to the injury and elicit rapid modulation of BP to manage OH. This review describes autonomic control of the cardiovascular system before injury, resulting cardiovascular consequences after SCI such as OH, and the clinical assessment tools for evaluating autonomic dysfunction after SCI. In addition, current approaches for clinically managing OH are outlined, and new promising interventions are described for managing this condition.

Abstract
Hypertension treatment has been implicated in falls, syncope, and orthostatic hypotension (OH), common events among older adults. Whether the choice of antihypertensive agent influences the risk of falls, syncope, and OH in older adults is unknown. ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) was a randomized clinical trial that compared the effects of hypertension first-step therapy on fatal coronary heart disease or nonfatal myocardial infarction (1994-2002). In a subpopulation of ALLHAT participants, age 65 years and older, we determined the relative risk of falls, syncope, OH, or a composite based on Centers for Medicare and Medicaid Services and Veterans Affairs claims, using Cox regression. We also determined the adjusted association of self-reported atenolol use (ascertained at the 1-month visit for indications other than hypertension) on outcomes in Cox models adjusted for age, sex, and race. Among 23 964 participants (mean age 69.8±6.8 years, 45% women, 31% non-Hispanic black) followed for a mean of 4.9 years, we identified 267 falls, 755 syncopes, 249 OH, and 1157 composite claims. There were no significant differences in the cumulative incidences of events across randomized drug assignments. However, amlodipine increased risk of falls during the first year of follow-up compared with chlorthalidone (hazard ratio [95% CI]: 2.24 [1.06-4.74]; P=0.03) or lisinopril (hazard ratio [95% CI]: 2.61 [1.03-6.72]; P=0.04). Atenolol use (N=928) was not associated with any of the 3 individual or composite claims. In older adults, the choice of antihypertensive agent had no effect on risk of fall, syncope, or OH long-term. However, amlodipine increased risk of falls within 1 year of initiation. These short-term findings require confirmation. Clinical Trial Registration- URL: http://www.clinicaltrials.gov. Unique identifier: NCT00000542.

Abstract
UNLABELLED Orthostatic hypotension is a major criterion for diabetic autonomic cardiac neuropathy. It increases overall and cardiovascular mortality. PURPOSE The aim of our study was to evaluate the orthostatic hypotension frequency in type 2 diabetics and to investigate the associated factors. METHODS This prospective cross-sectional study included adult patients with type 2 diabetes. Orthostatic hypotension was defined as a decrease in the systolic arterial pressure>20mm-Hg or a decrease in the diastolic arterial pressure>10mm-Hg, after 3minutes of standing position. The arterial pressure was measured with a validated electronic device. Vascular risk factors and micro and macro-vascular complications were systematically investigated by the appropriate diagnostic means. RESULTS We evaluated 300 diabetic patients. Of these women represented 57%. The mean age was 58 years old. The average duration of diabetes was 8 years. The antidiabetic drugs were metformin (82%), sulfonylureas (36%) and insulin (40%). High blood pressure was present in 49% among whom 50% of patients received angiotensin II receptor blockers, 47% diuretics, 24% angiotensin converting enzyme inhibitors, 17% beta blockers, and 17% calcium channel blockers. Orthostatic hypotension has been identified in 26 patients (8.6%). In multivariate analysis, the associated factors with orthostatic hypotension were elevated systolic blood pressure and insulin treatment. CONCLUSION The frequency of orthostatic hypotension is relatively low in our patients with type 2 diabetes and it was significantly associated with systolic blood pressure and insulin treatment.

Abstract
Pain and other symptoms of autonomic dysregulation such as hypertension, dyspnoea and bladder instability can lead to intractable suffering. Incorporation of neuromodulation into symptom management, including palliative care treatment protocols, is becoming a viable option scientifically, ethically, and economically in order to relieve suffering. It provides further opportunity for symptom control that cannot otherwise be provided by pharmacology and other conventional methods.

Abstract
BACKGROUND/OBJECTIVES Falls are frequent and often devastating events among older adults. Cardiovascular disease (CVD) is associated with greater fall risk; however, it is unknown if pathways that contribute to CVD, such as subclinical myocardial damage or wall strain, are related to future falls. We hypothesized that elevations in high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), measured in older adults, would be associated with greater fall risk. DESIGN Prospective cohort study. SETTING AND PARTICIPANTS Atherosclerosis Risk in Communities Study participants without known coronary heart disease, heart failure, or stroke. MEASUREMENTS We measured hs-cTnT or NT-proBNP in 2011 to 2013. Falls were identified from hospital discharge International Classification of Diseases, Ninth Revision (ICD-9), codes or Centers for Medicare and Medicaid Services claims. We used Poisson models adjusted for age, sex, and race/study center to quantify fall rates across approximate quartiles of hs-cTnT (less than 8, 8-10, 11-16, and 17 or greater ng/L) and NT-proBNP (less than 75, 75-124, 125-274, and 275 or greater pg/mL). We used Cox models to determine the association of cardiac markers with fall risk, adjusted for age, sex, race/center, and multiple fall risk factors. RESULTS Among 3973 participants (mean age = 76 ± 5 years, 62% women, 22% black), 457 had a subsequent fall during a median follow-up of 4.5 years. Incidence rates across quartiles of hs-cTnT and NT-proBNP were 17.1, 20.0, 26.2, and 36.4 per 1000 person-years and 12.8, 22.2, 28.7, and 48.4 per 1000 person-years, respectively. Comparing highest vs lowest quartiles of either hs-cTnT or NT-proBNP demonstrated a greater than two-fold higher fall risk, with hazard ratios of 2.17 (95% confidence interval {CI} = 1.60-2.95) and 2.34 (95% CI = 1.73-3.16), respectively. In a joint model, the relationships of hs-cTnT and NT-proBNP with falls were significant and independent. CONCLUSION Subclinical elevations of cardiac damage and wall strain were each associated with a higher fall risk in older adults. Further research is needed to determine whether interventions that lower hs-cTnT or NT-proBNP also lower fall risk. J Am Geriatr Soc 67:1795-1802, 2019.

Effects of Prolonged Head-Down Bed Rest on Cardiac and Vascular Baroreceptor Modulation and Orthostatic Tolerance in Healthy Individuals. Front Physiol 2019; 10:1061. [PMID: 31507438 PMCID: PMC6716544 DOI: 10.3389/fphys.2019.01061] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 08/02/2019] [Indexed: 11/13/2022] Open
Abstract
Orthostatic intolerance commonly occurs after prolonged bed rest, thus increasing the risk of syncope and falls. Baroreflex-mediated adjustments of heart rate and sympathetic vasomotor activity (muscle sympathetic nerve activity – MSNA) are crucial for orthostatic tolerance. We hypothesized that prolonged bed rest deconditioning alters overall baroreceptor functioning, thereby reducing orthostatic tolerance in healthy volunteers. As part of the European Space Agency Medium-term Bed Rest protocol, 10 volunteers were studied before and after 21 days of −6° head down bed rest (HDBR). In both conditions, subjects underwent ECG, beat-by-beat blood pressure, respiratory activity, and MSNA recordings while supine (REST) and during a 15-min 80° head-up tilt (TILT) followed by a 3-min −10 mmHg stepwise increase of lower body negative pressure to pre-syncope. Cardiac baroreflex sensitivity (cBRS) was obtained in the time (sequence method) and frequency domain (spectrum and cross-spectrum analyses of RR interval and systolic arterial pressure – SAP, variability). Baroreceptor modulation of sympathetic discharge activity to the vessels (sBRS) was estimated by the slope of the regression line between the percentage of MSNA burst occurrence and diastolic arterial pressure. Orthostatic tolerance significantly decreased after HDBR (12 ± 0.6 min) compared to before (21 ± 0.6 min). While supine, heart rate, SAP, and cBRS were unchanged before and after HDBR, sBRS gain was slightly depressed after than before HDBR (sBRS: −6.0 ± 1.1 versus −2.9 ± 1.5 burst% × mmHg−1, respectively). During TILT, HR was higher after than before HDBR (116 ± 4 b/min versus 100 ± 4 b/min, respectively), SAP was unmodified in both conditions, and cBRS indexes were lower after HDBR (α index: 3.4 ± 0.7 ms/mmHg; BRSSEQ 4.0 ± 1.0) than before (α index: 6.4 ± 1.0 ms/mmHg; BRSSEQ 6.8 ± 1.2). sBRS gain was significantly more depressed after HDBR than before (sBRS: −2.3 ± 0.7 versus −4.4 ± 0.4 burst% × mmHg−1, respectively). Our findings suggest that baroreflex-mediated adjustments in heart rate and MSNA are impaired after prolonged bed rest. The mechanism likely contributes to the decrease in orthostatic tolerance.

A practical guide to active stand testing and analysis using continuous beat-to-beat non-invasive blood pressure monitoring. Clin Auton Res 2019; 29:427-441. [PMID: 31076939 DOI: 10.1007/s10286-019-00606-y] [Citation(s) in RCA: 55] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Accepted: 04/02/2019] [Indexed: 12/19/2022]
Abstract
PURPOSE The average adult stands approximately 50-60 times per day. Cardiovascular responses evoked during the first 3 min of active standing provide a simple means to clinically assess short-term neural and cardiovascular function across the lifespan. Clinically, this response is used to identify the haemodynamic correlates of patient symptoms and attributable causes of (pre-)syncope, and to detect autonomic dysfunction, variants of orthostatic hypotension, postural orthostatic tachycardia syndrome and orthostatic hypertension. METHODS This paper provides a set of experience/expertise-based recommendations detailing current state-of-the-art measurement and analysis approaches for the active stand test, focusing on beat-to-beat BP technologies. This information is targeted at those interested in performing and interpreting the active stand test to current international standards. RESULTS This paper presents a practical step-by-step guide on (1) how to perform active stand measurements using beat-to-beat continuous blood pressure measurement technologies, (2) how to conduct an analysis of the active stand response and (3) how to identify the spectrum of abnormal blood pressure and heart rate responses which are of clinical interest. CONCLUSION Impairments in neurocardiovascular control are an attributable cause of falls and syncope across the lifespan. The simple active stand test provides the clinician with a powerful tool for assessing individuals at risk of such common disorders. However, its simplicity belies the complexity of its interpretation. Care must therefore be taken in administering and interpreting the test in order to maximise its clinical benefit and minimise its misinterpretation.

Abstract
OBJECTIVE To determine the effects of orthostatic hypotension (OH) measurement timing on its associations with dizziness, falls, fractures, cardiovascular disease (CVD), and mortality. METHODS We analyzed OH measurements from the Action to Control Cardiovascular Risk in Diabetes BP trial, which evaluated two blood pressure (BP) goals (systolic BP [SBP] < 120 mm Hg vs. SBP < 140 mm Hg) and incident CVD among adults with diabetes and hypertension. Seated BP was measured after 5 minutes of rest at baseline and follow-up visits (12 months, 48 months, and exit). Standing BP was measured 3 consecutive times (M1-M3) after standing, starting at 1 minute with each measurement separated by 1 minute. Consensus OH was defined as a drop in SBP ≥ 20 mm Hg or diastolic BP (DBP) ≥ 10 mm Hg. Participants were asked about orthostatic dizziness, recent falls, and recent fractures, and underwent surveillance for CVD events and all-cause mortality. RESULTS There were 4,268 participants with OH assessments over 8,450 visits (mean age 62.6 years [SD = 6.6]; 46.6% female; 22.3% black). Although all measures of consensus OH were significantly associated with dizziness, none were associated with falls, and only M2 (~3 minutes) was significantly associated with fractures. No measurements were associated with CVD events, but later measurements were significantly associated with mortality. BP treatment goal did not increase risk of OH regardless of timing. Associations were not consistently improved by the mean or minimum of M1-M3. CONCLUSION In this population of adults with hypertension and diabetes, neither single time nor set of measurements were clearly superior with regard to outcomes. These findings support the use of a flexibly timed, single measurement to assess OH in clinical practice. CLINICAL TRIALS REGISTRATION Trial Number NCT00000620.

Abstract
Disturbances of balance, gait and posture are a hallmark of parkinsonian syndromes. Recognition of these axial features can provide important and often early clues to the nature of the underlying disorder, and, therefore, help to disentangle Parkinson’s disease from vascular parkinsonism and various forms of atypical parkinsonism, including multiple system atrophy, progressive supranuclear palsy, and corticobasal syndrome. Careful assessment of axial features is also essential for initiating appropriate treatment strategies and for documenting the outcome of such interventions. In this article, we provide an overview of balance, gait and postural impairment in parkinsonian disorders, focusing on differential diagnostic aspects.

Abstract
AIM Orthostatic blood pressure (BP) can fall with reduced stroke volume and arterial elasticity. However, as the reason for orthostatic BP rise is unclear, we investigated the relationship of orthostatic BP rise with frailty in older patients. METHODS In 169 consecutive outpatients who visited the frailty clinic, we evaluated orthostatic BP and heart rate changes (i.e. in the sitting position, just after standing up, 1 min after standing and after sitting down). Frailty was evaluated using the Kihon Checklist (KCL) established by the Ministry of Health, Labor and Welfare. RESULTS The mean age was 77.4 ± 6.9 years, and 29% of patients had frailty with a KCL score ≥8. The systolic BP declined in both groups, but patients with frailty experienced a smaller decrease just after standing (-0.2 ± 10.3 vs -6.2 ± 11.5, P = 0.001). During standing for 1 min, elevation of systolic BP was greater in patients with frailty than in those without (8.4 ± 11.6 mmHg vs 3.2 ± 11.2 mmHg, P = 0.009). The difference in elevation of systolic BP remained significant, even after adjusting for confounding factors including systolic BP before standing (P = 0.013). In particular, the KCL score for motor function was significantly correlated with an elevation of orthostatic systolic BP after standing for 1 min, even after controlling for systolic BP before standing and confounding factors (P = 0.020). CONCLUSIONS The elevation of systolic BP after standing for 1 min was greater in patients with frailty as diagnosed by the KCL score, especially in relation to reduced motor function.

Abstract
The Systolic Blood Pressure Intervention Trial (SPRINT) compared the clinical outcomes between target systolic blood pressure (SBP) levels between 140 and 120 mmHg or lower. Both,the 2017 ACC/AHA and the 2018 ESC/ESH guidelines in hypertension are derived from the SPRINT trial and advise initiation and/or intensification of treatment at lower blood pressure thresholds. The ACC/AHA guidance supersedes the 2014 Eight Joint National Committee guideline (JNC-8) which advised initiation of treatment when the BP was 140/90 mmHg or higher; in adults 60 years or over, the target was 150/90 mmHg. Compared to JNC-8, the new guidelines lower the SBP target by 10 mmHg in patients under age of 60 years, and by 20 mmHg in the elderly. We performed a qualitative multi-dimensional analysis in order to answer two key questions: will the new guidelines deliver the stated benefits? and, will translation to the clinic be simple, risk-free, and affordable? A major investment by national healthcare administrations will be necessary for the initiation and support of this program but this decision can only be justified by a valid expectation of clinical benefit. At this time, a definitive answer is not available and a "wait and see" attitude appears appropriate and reasonable. In the interim, efforts are best directed to the immediate problem of untreated hypertension worldwide.

Abstract
BACKGROUND/OBJECTIVES A lower risk of falls is commonly cited as a reason to treat hypertension conservatively in older individuals. We examined the effect of hypertension treatment and control status and measured blood pressure (BP) level on the risk of falls in older women. DESIGN/SETTING Prospective cohort study. PARTICIPANTS A total of 5971 women (mean age 79 years; 50.4% white, 33.1% black, 16.5% Hispanic/Latina) enrolled in the Women's Health Initiative and Objective Physical Activity and Cardiovascular Health study. MEASUREMENTS BP was measured by trained nurses, and hypertension treatment was assessed by medication inventory. Participants mailed in monthly calendars to self-report falls for 1 year. RESULTS Overall, 70% of women had hypertension at baseline (53% treated and controlled, 12% treated and uncontrolled, 5% untreated). There were 2582 women (43%) who reported falls in the 1 year of surveillance. Compared with nonhypertensive women, when adjusted for fall risk factors and lower limb physical function, the incidence rate ratio (IRR) for falls was 0.82 (confidence interval [CI] = 0.74-0.92) in women with treated controlled hypertension (p = .0008) and 0.73 (CI = 0.62-0.87) in women with treated uncontrolled hypertension (p = .0004). Neither measured systolic nor diastolic BP was associated with falls in the overall cohort. In women treated with antihypertensive medication, higher diastolic BP was associated with a lower risk of falls in a model adjusted for fall risk factors (IRR = 0.993 per mm Hg; 95% CI = 0.987-1.000; p = .04). The only class of antihypertensive medication associated with an increased risk of falls compared with all other types of antihypertensive drugs was β-blockers. CONCLUSION Women in this long-term research study with treated hypertension had a lower risk of falls compared with nonhypertensive women. Diastolic BP (but not systolic BP) is weakly associated with fall risk in women on antihypertensive treatment (<1% decrease in risk per mm Hg increase). J Am Geriatr Soc, 2019.
