Effects of the combination of acupuncture and medication on orthostatic hypotension after incomplete cervical spinal cord injury / 针灸推拿医学（英文版）

Objective: To observe the effect of the combination of acupuncture and medication on orthostatic hypotension after incomplete cervical spinal cord injury. Methods: Ninety-two patients with orthostatic hypotension after incomplete cervical spinal cord injury were divided into two groups according to the random number table method, with 46 cases in each group. The control group was treated with oral midodrine hydrochloride on the basis of conventional treatment, and the observation group was treated with acupuncture in addition to the intervention used in the control group. Both groups were treated for 4 weeks. The changes in supine and orthostatic blood pressures, motor and sensory scores, quadriplegic function index score, clinical efficacy, and safety evaluation were observed. Results: During the treatment, 2 cases dropped out in the observation group, and 3 cases dropped out in the control group. After 4 weeks of treatment, the clinical efficacy of the observation group was better than that of the control group (P<0.05). After treatment, the supine systolic blood pressure and diastolic blood pressure in the two groups had no significant changes (P>0.05), while the orthostatic systolic blood pressure and diastolic blood pressure, the motor and sensory scores, and the quadriplegic function index score were significantly higher than those before treatment (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05). Adverse reactions were mild in both groups. Conclusion: The combination of acupuncture and medication can significantly improve the orthostatic blood pressure, motor and sensory function and daily living ability of patients with orthostatic hypotension after incomplete cervical spinal cord injury, and it is safe and reliable.

A pilot study on the clinical characteristics of blood pressure circadian rhythm disorder and its impact on orthostatic hypotension in Parkinson′s disease / 中华神经科杂志

Objective:To investigate the clinical characteristics of circadian rhythm disorder of blood pressure and its impact on orthostatic hypotension (OH) in Parkinson′s disease (PD).Methods:A total of 165 PD patients from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from August 2019 to October 2021 were consecutively enrolled. Medical history and scores of motor and non-motor symptoms of patients were collected. Twenty-four-hour ambulatory blood pressure and OH data were collected, and the OH questionnaire was completed. The incidence of each type of circadian rhythm disorder of blood pressure was investigated. The t test, chi-square test and Mann-Whitney U test were used to determine between-group differences of circadian rhythm disorder of blood pressure. The linear trends in clinical characteristics were tested by linear regression analysis. Logistic regression analysis was used to analyze the relationship between different circadian rhythm disorders of blood pressure and OH as well as symptomatic OH (SOH). Results:In 165 PD patients, the incidence of reverse dipping pattern was 39.39% (65/165), nocturnal hypertension was 43.64% (72/165), and awakening hypotension was 31.52% (52/165). Compared with patients without reverse dipping pattern, patients with reverse dipping pattern were older [(71.72±7.81) years vs (65.29±9.68) years, t=-4.491, P<0.001], had later onset age [(66.67±9.10) years vs (62.16±10.66) years, t=-2.809, P=0.006], longer duration [36.00(20.50, 95.50) months vs 24.00(12.00, 41.75) months, Z=-3.393, P<0.001], higher dose of levodopa (LD) [(426.15±267.38) mg/d vs (284.00±235.58) mg/d, t=-3.590, P<0.001], higher levodopa equivalent dose (LED) [(514.80±360.03) mg/d vs (341.44±284.57) mg/d, t=-3.440, P=0.001], higher Unified Parkinson′s Disease Rating Scale (UPDRS)-Ⅱ scores (12.92±6.38 vs 9.54±5.59, t=-3.434, P=0.001), higher UPDRS-Ⅲ scores (28.34±11.60 vs 21.41±12.18, t=-3.508, P=0.001) and higher percentages of hallucinations [18.46% (12/65) vs 7.00% (7/100), χ2 =5.079, P=0.024]. Compared with patients without awakening hypotension, patients with awakening hypotension were older [(70.83±7.09) years vs (66.44±10.16) years, t=-2.811, P=0.006]. Compared with patients without nocturnal hypertension, patients with nocturnal hypertension had longer duration [39.50(15.00, 96.00) months vs 24.00 (12.00, 36.00) months, Z=-2.944, P=0.003], higher LD [(398.61±251.19) mg/d vs (294.62±254.25) mg/d, t=-2.619, P=0.010], higher LED [(493.28±344.02) mg/d vs (345.05±298.59) mg/d, t=-2.959, P=0.004], higher percentages of hallucinations [19.44% (14/72) vs 5.38% (5/93), χ2 =7.882, P=0.005], higher UPDRS-Ⅱ scores (12.08±6.33 vs 10.00±5.86, t=-2.086, P=0.039), higher UPDRS-Ⅲ scores (26.50±11.72 vs 22.42±12.66, t=-2.034, P=0.044), and greater blood pressure variability (BPV) (20.66±5.47 vs 17.44±5.36, t=-3.798, P<0.001). Trend analysis showed that the variety of circadian rhythm was positively correlated with age and duration, use of levodopa and monoamine oxidase B inhibitors and amantidine, morning and daily LD and LED, UPDRS-Ⅱ, UPDRS-Ⅲ and Hamilton Anxiety Scale scores, hallucinations, OH and SOH, and BPV in PD ( P<0.05). Multivariate Logistic regression analysis showed that awakening hypotension ( OR=3.35, 95% CI 1.55-7.22, P=0.002) and nocturnal hypertension ( OR=2.44, 95% CI 1.20-4.97, P=0.014) were risk factors for OH, and LED ( OR=1.21, 95% CI 1.01-1.43, P=0.035), UPDRS-Ⅲ scores ( OR=1.09, 95% CI 1.02-1.16, P=0.009) and w-BPV ( OR=1.14, 95% CI 1.01-1.29, P=0.029) were independent risk factors for SOH. Conclusions:Circadian rhythm disorder of blood pressure was correlated with age, duration, severity of motor symptoms. Awakening hypotension and nocturnal hypertension are independent risk factors for OH in PD.

Progress in diagnosis and treatment of orthostatic intolerance / 中华老年医学杂志

Orthostatic intolerance is a syndrome characterized by a series of symptoms that occur when standing upright, resulting in the loss of ability to maintain an upright position.This condition can be further classified into orthostatic hypotension, postural orthostatic tachycardia syndrome, and vasovagal syncope.Some scholars suggest that orthostatic hypertension may also be considered a part of this syndrome.The most significant risk associated with orthostatic intolerance is falls, which can lead to physical injury and psychological distress.This article aims to review the advancements made in the diagnosis and treatment of orthostatic intolerance, so as to enhance the standardization of clinical diagnosis and improve the effectiveness of treatment.

Autonomic nervous symptoms as the initial presentation in systemic light-chain amyloidosis with multiple myeloma: a case report / 中华神经科杂志

Immunoglobulin light chain amyloidosis (AL) is characterized by the extracellular tissue deposition of insoluble fibrils as a result of protein misfolding. These tissue deposits may be responsible for progressive failure in several organs. Among them, neuropathy may be presented as the first manifestation. The patient reported here presented initially with autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. Moreover, since the systemic involvement of the disease, the patient also presented with diarrhea, peripheral polyneuropathy, and kidney dysfunction. Eventually, the massive myocardial depression and infiltration led to a fatal outcome due to ventricular fibrillation. Examination revealed M protein in serum and urine protein electrophoresis. Rectal mucosa and skin biopsy confirmed amyloidosis, and bone marrow biopsy showed cellular infiltration was over 35% with 23% immature plasma cells. The patient was confirmed as AL with multiple myeloma.

A Prevalência da Hipotensão Ortostática e a Distribuição da Variação Pressórica no Estudo Longitudinal da Saúde do Adulto / Prevalence of Orthostatic Hypotension and the Distribution of Pressure Variation in the Longitudinal Study of Adult Health

Resumo Fundamento A hipotensão ortostática (HO) tem sido negligenciada na clínica não havendo estudos sobre sua prevalência na população brasileira. Objetivo Determinar a prevalência de HO e a variação da pressão arterial (PA) após manobra postural no Estudo Longitudinal da Saúde do Adulto. Métodos No presente estudo descritivo da linha de base (N = 14.833 indivíduos, 35-74 anos), os participantes ficavam deitados por 20 minutos e então levantavam ativamente, com a medida da PA em supino e aos 2, 3, e 5 minutos de ortostase. A HO foi definida por queda ≥ 20 mmHg na PA sistólica e/ou queda ≥ 10 mmHg na PA diastólica aos 3 minutos, sendo determinada a sua prevalência com intervalo de confiança de 95% (IC95%). A distribuição da variação da PA após a manobra postural foi determinada numa subamostra (N = 8.011) após remoção de participantes com morbidade cardiovascular e/ou diabetes. Resultados A prevalência de HO foi de 2,0% (IC95%: 1,8 - 2,3), crescente com a idade. Se o critério for a mesma queda pressórica em qualquer das medidas, a prevalência aumenta para 4,3% (IC95%: 4,0 - 4,7). Em presença de HO houve relato de sintomas (tontura, escotomas, náuseas, etc.) em 19,7% dos participantes (IC95%: 15,6 - 24,6) e em apenas 1,4% (IC95%: 1,2 - 1,6) dos sem HO. Os escores-Z −2 das variações da PA antes e após manobra postural na subamostra foram de −14,1 mmHg na PA sistólica e −5,4 mmHg na diastólica. Conclusão A prevalência de HO varia em função do momento da aferição da PA. Os pontos de corte atuais podem subestimar a ocorrência de HO na população. (Arq Bras Cardiol. 2020; 114(6):1040-1048)

Abstract Background Orthostatic hypotension (OH) has been neglected in clinical practice, and there are no studies on its prevalence in the Brazilian population. Objective To determine the prevalence of OH and blood pressure (BP) changes after the postural change maneuver in participants of the Longitudinal Study of Adult Health. Methods In this descriptive study of baseline data (N = 14,833 adults, ages 35 - 74 years), participants remained lying down for 20 minutes and subsequently stood up actively. BP measurements were taken while the participants were supine and at 2, 3, and 5 minutes after standing. OH was defined as a reduction of ≥ 20 mmHg in systolic BP and/or a reduction of ≥ 10 mmHg in diastolic BP at 3 minutes, and its prevalence was determined with a 95% confidence interval (CI). The distribution of BP variation after the postural change maneuver was determined in a subsample (N = 8,011) obtained by removing patients with cardiovascular morbidity and/or diabetes. Results The prevalence of OH was 2.0% (95% CI: 1.8 - 2.3), increasing with age. If the criterion applied were a BP reduction during any measurement, the prevalence would increase to 4.3% (95% CI: 4.0 - 4.7). Symptoms (dizziness, scotoma, nausea, etc.) were reported by 19.7% of participants (95% CI: 15.6 - 24.6) with OH and 1.4% (95% CI: 1.2 - 1.6) of participants without OH. The −2 Z-scores of BP variation before and after the postural change maneuver in the subsample were −14.1 mmHg for systolic BP and −5.4 mmHg for diastolic BP. Conclusion Prevalence of OH varies depending on when BP is measured. Current cutoff points may underestimate the actual occurrence of OH in the population. (Arq Bras Cardiol. 2020; 114(6):1040-1048)

Analysis on the characteristics of postural blood pressure changes recorded with continuous non-invasive arterial pressure monitoring system and the correlative factors in elderly hospitalized patients / 中华心血管病杂志

Objective@#To explore the characteristics of postural blood pressure changes in elderly inpatients and the related factors of orthostatic hypotension (OH).@*Methods@#This study was a clinical case control study. Two hundred and sixty-six elderly patients (≥60 years old), who were hospitalized between April 2016 and November 2017 in Geriatric Department of Peking University First Hospital, were included. They were divided into direct standing group and indirect standing group. Direct standing group involved 102 patients, they changed posture from supine directly to standing position, and the blood pressures at the moments of supine, immediately after standing and the first, second, and third minute after standing were recorded by continuous noninvasive arterial pressure (CNAP) system. Indirect standing group involved 164 patients, and they changed posture from supine to sitting for 3 minutes, and then changed to standing position. Blood pressures at the moments of supine, immediately after sitting, the third minute after sitting, immediately after standing and the third minute after standing was recorded by CNAP. Blood pressure changes after different postural changes mode and the rates of OH were compared. The related factors of OH was analyzed by binary logistic regression analysis.@*Results@#The lowest systolic blood pressures (SBP) mostly occurred immediately after postural change: immediately after standing for direct standing group (86.3%(88/102)), and immediately after sitting for indirect standing group (59.1%(97/164)). The lowest diastolic blood pressures (DBP) mostly occurred immediately after standing in the two groups: 87.3%(89/102) for direct standing group and 43.3% (71/164) for indirect standing group. The maximum SBP drop (SBP of supine minus the lowest SBP during postural changes) of direct standing group was significantly higher than indirect standing group (median 20.5(14.0, 29.3) vs. 18.0(11.0, 26.0) mmHg (1 mmHg=0.133 kPa, P<0.05). The rates of OH occurred immediately and within 3 minutes from supine to standing position were significantly higher in direct standing group than in indirect standing group (65.7% (67/102) vs. 43.9% (72/164), and 70.6% (72/102) vs. 49.4% (81/164), both P<0.05). Binary logistic regression analysis showed that brachial-ankle pulse wave velocity was positively associated with OH after a transition from supine to standing position (immediately and within 3 minutes, OR=1.002 (95%CI 1.000-1.004), 1.003 (95%CI 1.001-1.006), P=0.014, 0.006) in direct standing group.@*Conclusions@#OH is common in elderly hospitalized patients. The most obvious blood pressure changes are likely to occur immediately after position changes. Adding a sitting position during the transition of supine to standing position may decrease the amplitude of SBP drop. Brachial-ankle pulse wave velocity is associated with OH after the transition from the supine to standing position in the elderly inpatients.

Heart Rate and its Variability Assessed by Spectral Analysis in Elderly Subjects with Orthostatic Hypotension: A Case-Control Study / Frequência Cardíaca e sua Variabilidade por Meio da Análise Espectral em Idosos com Hipotensão Ortostática: Estudo de Caso-Controle

Abstract Background: The prevalence of orthostatic hypotension (OH) increases with age and is associated with changes in autonomic regulation of blood pressure (BP) and heart rate (HR). Objective: to assess HR and HR variability (HRV) in elderly subjects with OH and determine OH predictors. Methods: a total of 105 patients aged ≥ 60 years, 39 with OH (case group) and 66 without OH (control group) (age-matched) were studied. Patients underwent clinical assessment, electrocardiogram, biochemistry tests and Holter monitoring for spectral analysis of HRV (Fourier transform) in the supine and orthostatism positions to identify low frequency (LF) and high frequency (HF) components, as well as the LF/HF ratio. Results: median age was 73.0 years, 64 patients were women. In all participants, there was a reduction in HF (133.0 versus 76.0 ms2, p = 0.001) and increase in LF/HF (1.6 vs 2.1; p < 0.001) and no change in LF (233.0 versus 218.0 ms2, p = 0.080). Between-group comparisons revealed significant differences in the median values of HR in the supine position (62.0 vs. 69.0 bpm, p = 0.001) and LF in the supine position (157.0 in case group vs. 275.0 ms2 in the control group, p = 0.014). Spearman's correlation coefficient of 0.27 was found between the groups. Multivariate analysis revealed that HR in the supine position was an independent variable for OH (p = 0.001- 95%CI = -0.022 and -0.006). Using the operating characteristic curve, the best cutoff point was 61 bpm, with a sensitivity of 77.3% and specificity of 51.3%, positive predictive value of 61.3%, and negative predictive value 69.3%. Odds ratio was 3.23 for OH in patients with a HR lower than 61 bpm. Conclusions: lower LF and HR in the supine position were found in patients with OH, regardless of age and gender. The independent predictor for OH was HR in the supine position, with an odds ratio of 3.23 for values lower than 61 bpm.

Resumo Fundamento: A prevalência de hipotensão ortostática (HO) aumenta com a idade e está relacionada a alterações da regulação autonômica da pressão arterial (PA) e da frequência cardíaca (FC). Objetivos: Avaliar a FC e variabilidade da FC (VFC) em idosos com HO e verificar os preditores de HO. Métodos: foram avaliados 105 pacientes, com idade ≥ 60 anos, 39 com HO (grupo caso) e 66 sem HO (grupo controle), pareados por idade. Foram submetidos à avaliação clínica, eletrocardiograma, exames de bioquímica e monitoramento pelo Holter para análise espectral da VFC (transformação de Fourier), na posição supina e em ortostatismo, para detectar os componentes de baixa frequência (LF), de alta frequência (HF) e sua relação LF/HF. Resultados: A mediana de idade foi de 73,0 anos, 64 dos pacientes eram mulheres. Em toda a população, com a mudança de posição, houve redução do HF (133,0 versus 76,0 ms2, p = 0,001) e aumento da relação LF/HF (1,6vs2,1; p < 0,001), sem alteração quanto à mediana do componente LF (233,0 versus 218,0 ms2, p = 0,080). Quando comparado o grupo caso ao grupo controle, houve diferença quanto às medianas da FC nas posições supina (62,0 vs 69,0 bpm, p = 0,001) e do componente LF na posição supina (157,0 no grupo caso vs 275,0 ms2 no grupo controle, p = 0,014). Quanto ao gênero, o coeficiente de Spearman foi de 0,27 entre os grupos. Pela análise multivariada, a FC na posição supina foi a variável independente para a ocorrência de HO (p = 0,001- IC95% = -0,022 e -0,006). Pela curva de operação característica, o melhor ponto de corte para FC foi de 61 bpm, com sensibilidade de 77,3%, especificidade de 51,3%, valor preditivo positivo de 61,3%, e o valor preditivo negativo de 69,3%. A razão de chance foi de 3,23 para HO entre os pacientes com FC < 61 bpm. Conclusões: Houve menor valor do LF e da FC na posição supina entre os pacientes com HO, sem influência da idade e do gênero. O preditor independente para HO foi a FC na posição supina, a qual apresentou uma razão de chance de 3,23 se inferior a 61 bpm.

The relationship between orthostatic hypotension and the risk of myocardial infarction in the elderly / 中华老年医学杂志

Objective To investigate the relationship between the systolic/diastolic orthostatic hypotension(OH S/OH-D) and myocardial infarction (MI) in the elderly.Methods 200 subjects without myocardial infarction (MI) aged 60 years and over in our urban district were selected.The orthostatic and supine blood pressure and heart rate were measured in supine position after resting for more than 5 minutes and at 0 and 2 minutes after standing.All eases were divided into systolic orthostatic hypotension(OH-S)or diastolic orthostatic hypotension(OH-D)groups based on the results of orthostatic hypotension,and followed up by telephone with mean period of 325 days.The primary endpoint was MI occurrence for analyzing the correlation between OH-S/OH-D and MI incidence.Results The prevalence rate of OH in this cohort was 38％,with OH-S 20％ and OH-D 18％.In the very elderly group(≥80 years)versus the elderly group,the occurrences of 0H and OH-S were(27％ vs.21 ％,P =0.036;22 ％ vs.15 ％,P =0.020),respectively,while no significant difference was found in OH-D between the two groups.After 325 day follow up,the prevalence of MI was significantly(P＜ 0.05)higher in the OH positive subjects than in the 0H negative subjects,which result was the same as the prevalence of MI in OH-S or and OH-D group.After adjusting for age,supine blood pressure,creatinine and cerebrovascular history,logistic regression analysis showed that MI was correlated with OH(HR 15.72,95％CI 3.29～74.23,P=0.002),OH-S(HR 8.552,95％CI 2.51～30.21,P=0.004)and OH-D(HR 3.80,95 ％CI 1.14～13.80,P=0.042).Compared with OH-D,OH-S had more significant correlation with MI.Conclusions Orthostatic hypotension,particularly systolic orthostatic hypotension,is common in elderly patients.The OH-S and OH-D have a significant correlation with MI.

Etiology of 96 syncope patients / 中华老年心脑血管病杂志

Objective To study the diagnosis and treatment of syncope by analyzing its etiology.Methods Ninety-six syncope patients admitted to our hospital from 2014-01-01 to 2016-12-21were included in this study.The etiology of syncope was analyzed.Results Of the 96 syncope patients included in this study,50 (52.1 ％) were diagnosed with nerve-mediated reflex syncope,31(32.3％) with orthostatic hypotensive syncope,10 (10.4％) with cardiogenic syncope due to arrhythmia,coronary atherosclerotic cardiopathy or pulmonary embolism,5 (5.2％) with other diseases.Conclusion Nerve-mediated reflex,orthostatic hypotension and cardiogenic factors are the causes of syncope.Attention should thus be paid to syncope caused by nervous system diseases.Clarification of the risk factors for syncope helps to reduce its potential risk.

Síncope em idosos / Syncope in the elderly

O quadro de síncope apresenta aumento de sua prevalência com a idade, alcançando até 19,5 por 1.000 indivíduos/ano, com morbidade por trauma, fraturas e piora da qualidade de vida. Além disto, a mortalidade dentro de um ano do episódio de síncope pode chegar a 33%, se a causa é cardíaca. As alterações relacionadas ao envelhecimento que ocorrem nos reflexos cardiovasculares e alterações anatômicas, em combinação com as comorbidades e o uso de medicamentos, levam ao aumento da incidência de síncopes em pessoas idosas. A identificação da causa da síncope é importante para o tratamento adequado, com melhora da qualidade de vida, prevenção de recorrência e de morte. O método clínico possibilita o diagnóstico em até 50% dos casos e o arsenal de exames complementares disponíveis deve ser solicitado de acordo com o raciocínio clínico.

The framework of syncope presents prevalence increases with age, reaching up to 19.5 per 1,000 individuals per year, with morbidity by trauma, fractures, and worsen quality of life. Furthermore, mortality within a year from the syncope episode may reach 33% if the cause is cardiac arrest. Aging-related changes that occur in the cardiovascular reflexes and anatomical changes, in combination with the comorbidities and use of medicines, lead to increased incidence of syncope in elderly people. The identification of the cause of syncope is important for appropriate treatment, with improved quality of life, prevention of recurrence and death. The clinical method enables the diagnosis by as much as 50% of cases, and the arsenal of complementary exams available must be requested according to the clinical reasoning.

Forty￣nine Cases of Shenmai Injection Administration for Elderly with Orthostatic Hypotension / 医药导报

Objective To investigate the effect of Shenmai injection in treating elderly with orthostatic hypotension. Methods The total of 97 cases of patients with orthostatic hypotension were randomly divided into 2 groups, which was injected intravenously with 100 mL Shenmai injection once daily as the treatment group, with 100 mL glucose as the control.The treatment lasted 14 days. The clinical symptom score, the difference of blood pressure, the P￣selectin, and the platelet maximum aggregation were measured. Results Compared with the control, Shenmai injection significantly reduced the clinical symptom scores of patients (P<0.05), lowered the difference of blood pressure for upright and supine significantly (P<0.05), decreased the platelet maximum aggregation and P￣selectin remarkably (P<0.05). Conclusion Shenmai injection significantly reduces the difference of blood pressure for upright and supine of the elderly with orthostatic hypotension, and inhibits the activities of platelets, thus improves the clinical symptoms.

Association between postural changes of blood pressure and carotid atherosclerosis in the elderly / 中华老年医学杂志

Objective To investigate association between postural changes of blood pressure and carotid atherosclerosis in the elderly.Methods Standardized questionnaires,physical examination and biochemical blood tests were performed to acquire clinical characteristics of the participants.Presences of carotid plaques were identified by carotid ultrasound examination.Orthostatic hypotension (OH) and orthostatic hypertension (OHT) were defined according to the international consensus.Multivariable logistic regression analysis was performed to analyze the associations of carotid plaques with OH and OHT.Results 377 old people were finally included,of which 101 had OH and 33 had OHT.After full adjustment for possible confounders,old people with carotid plaques had significantly increased risk for OH as compared with those without carotid plaques (OR=2.27,95％ CI:1.32-3.90,P=0.003).Participants with bilateral carotid plaques were associated with significantly increased risk for OH (OR=3.45,95％CI:1.74 6.84,P=0.001),while the association between unilateral carotid plaques and OH was not significant (OR=1.71,95％ CI:0.88-3.32,P=0.112).No significant association was identified between carotid plaques (bilateral or unilateral) and OHT.Conclusions Presence of carotid plaques,particularly bilateral plaques,may be an independent risk factor for OH.

Investigation of the relationship between antihypertensive medication and orthostatic blood pressure changes in the elderly hypertensive inpatients / 中国医师杂志

Objective To observe the incidence of orthostatic hypotension and hypertension in the elderly hypertensive inpatients and investigate the effect of antihypertensive medication on the orthostatic blood pressure changes in the elderly hypertensive inpatients.Methods A total of 185 aged hypertensive inpatients was divided into elderly group(n =126,60～79 years old) and very elderly group(n =59,≥80 years old) according to the age.The orthostatic blood pressure was measured in supine position and after standing.Subjects were divided into 3 subgroups:orthostatic hypotension (OH),orthostatic hypertension (OHT),and orthostatic normotension (ONT) groups according to the standing blood pressure levels.Clinical characteristics of each subgroup were evaluated and analyzed according to the antihypertensive medication.Results Among 185 patients,the OH incidence was 31 (16.76％) cases,the OHT incidence was 23 (12.43 ％) cases,and the ONT incidence was 131 (70.81％) cases.There were 16 (12.70％) patients with OH and 10(7.90％) patients with OHT in elderly group,but 15 (25.42％) patients with OH and 13 (22.03％) patients with ONT in very elderly group.The prevalence of OH and OHT in each elderly group was both higher than elderly group (P ＜ 0.05).Antihypertensive medications such as Calcium channel blockers,angiotensin Ⅱ receptor-blockers,Beta-blockers,diuretics,and angiotensin converting enzyme inhibitors were not significantly different among three subgroups.Conclusions OH and OHT were common in the elderly hypertensive inpatients,especially in the very elderly people.The five-class antihypertensive medication that doctors commonly used at present might be not related to the orthostatic hypotension and hypertension.

Homem, 78 anos, com hipotensão ortostática neurogênica incapacitante não responsiva e terapêutica clássica, admitido em hospital para implantação de marca-passo atrial programável. Inicialmente, implantou-se marca-passo atrial temporário, a frequencia de 96 bpm (dia) e 60 bpm (noite). Observou-se melhora dos sintomas, justificando a implantação de marca-passo definitivo. Recomenda-se considerar esta modalidade terapeutica em idosos com hipotensão ortostática neurogênica sem taquicardia compensatória quando não houver resposta a tratamento clássico.

A 78-year-old male patient with incapacitating neurogenic orthostatic hypertension was admitted in hospital for implantation of programmable pacemaker after no response to classic treatment. The initial procedure consisted in implanting a temporary pacemaker at a frequency of 96 BPM in the morning and 60 BPM at night. A definitive pacemaker was implanted because of the improvement of symptoms. Such treatment modality is herein recommended for elderly patients suffering from neurogenic orthostatic hypotension without compensatory tachycardia when they show no positive response to the classic treatment.

Clinical research on postural hypotension in in-hospital elderly patients / 中国医师杂志

Objective To observe the clinical feature of postural hypotension (PH) in in-hospital elderly patients. Methods Measure the supine and orthostatic blood pressure in patients were measured, and the clinical characteristics of PH and clinical incident during hospital stay were analyzed. Results (1)The PH incidence in elderly patients was 24. 11% ; (2)The incidence of systolic blood pressure PH was higher in patients with concomitant hypertension and diabetes ( P ＜ 0.05 & P ＜0.01), especially in those with relatively higher basal systolic blood pressure and diastolic blood pressure ( P ＜ 0.001); the percentage of patients taking diuretics ( P ＜ 0. 05) and calcium antagonists ( P ＜ 0. 01) were relatively higher in patients with diastolic blood pressure PH; (3)Systolic blood pressure in patients from the group with PH lowered (31 ±25) mmHg, while diastolic blood pressure lowered (11 ±15) mmHg; (4)The incidence of clinical events, including dizziness or vertigo, syncope or pre-syncope, angina pectoris or new-onset myocardial infarction, and new-onset stroke, in PH patients was distinctly higher than that in patients from the group without PH ( P ＜0. 01).Conclusion PH is a kind of common clinical manifestations in elderly patients, which tends to induce tumbling, angina pectoris, stroke, etc, and ought to be paid great attention to and taken preventive measures.

The effect of nursing intervention on postnral hypotension of aged with heart disease / 中国基层医药

Objective To study the effect of nursing intervention on postural hypotension of aged with heart disease.Methods Nursing intervention were gived to the 68 aged patients with heart disease and postural hypotension.The effect of nursing intervention on postural hyporension and hypotension associated symptoms were observed.Results The postural hypotension was improved and the incidence of hypotension associated symptoms were reduced after nursing intervention.Differences were statistically significant(P＜0.01).Conclusion Nursing intervention was effective on the improvement of postural hypotension.
