Orthostatic Hypotension Research Articles

Effects of mobilization within the first 4 h following anatomical lung resection with thoracotomy.

Thoracic incisions are very painful and complicated incisions. Many analgesic drugs including opioids are used to relieve pain in patients. We hypothesized that early mobilization and patient-centered strategy after lung resection reduce the incidence of perioperative complications and postoperative pain. We conducted a retrospective study on patients who underwent lung resection via thoracotomy and were mobilized in the first 4h postoperatively. Mobilization was defined as standing and walking at least 100m from the bed. If orthostatic hypotension occurred, mobilization was postponed for 30min. Analgesic treatment needs, walking distance, co-morbidity, hospitalization, postoperative complications within 30 days, and drainage and discharge times of patients were analyzed. The lobectomy with thoracotomy was performed in 48 patients. Thirty-six patients were male. The rate of additional systemic diseases was 58.3%. Forty patients walked in the first 3 h postoperatively. The mean walking distance was 140 ± 38.5m. The rate of orthostatic hypotension was 8.3%. The routine analgesic treatment included intravenous paracetamol 3g and dexketoprofen 100mg daily. In this study, 18% of patients received narcotic analgesics. Thromboembolic event and arrhythmia did not develop in any patient. The most common complication was prolonged air leaks (18.8%). Mobilization within the first 4h following anatomical lung resection is feasible and safe. Early mobilization provided pain relief after lung surgery and reduced the use of narcotic analgesics and cardiovascular complications. The article is the first study about walking in first hours after pulmonary lobectomy with thoracotomy in the thoracic surgery literature.

Adverse events related to alpha-blockers: analysis of real-life data from Eudra-Vigilance.

Patients on alpha-blockers (ABs) treatment may have an increased risk of adverse events (AEs). Aim of our study was to compare real-life data on neuro-vascular and sexual AEs associated with ABs based on Eudra-Vigilance reported AEs. Eudra-Vigilance (EV) database is the system for managing and analyzing information on suspected adverse reactions to medicines which have been authorized or being studied in clinical trials in the European Economic Area (EEA). We recorded the number of sexual and neuro-vascular AEs for tamsulosin, alfuzosin, silodosin, prazosin and doxazosin per category and severity until July 30th, 2022. Pooled Relative Risk (PRR) was used to compare data between drugs. Overall the number of AEs were 2842 for Alfuzosin, 11,086 for tamsulosin, 792 for terazosin, 572 for prazosin and 4641 for doxazosin. Different percentages of AEs were obtained for each drug and in different age groups according to EV sub-groups (≤65, 65-85, ≥85). On PRR analysis, the risk of ejaculatory disorders for Silodosin (11%) is 18.5 times higher (PRR 18.5 95%CI; 10.7-31.8; P<0.05) when compared to alfuzosin and the risk of orthostatic hypotension is 2 times lower (PRR=1,84 95%CI 1.32-2.57; P<0.05). Real life data is consistent with registry studies regarding side effects related to alpha-blockers. Alfuzosin is safer in terms of ejaculatory disorders while silodosin and tamsulosin in terms of orthostatic hypotension. Clinicians should consider these data when prescribing ABs especially in younger and older patients.

Effect of Silodosin in the Treatment of Distal Ureteral Stone

Background: Ureteral stones are a common type of urinary tract stones, accounting for 20% of all cases. The majority of these stones, approximately 70%, are located in the distal ureter. Recent studies have shown that α1- Adrenergic blockers can enhance the spontaneous passage of distal ureteral stones. Objectives: This study was done to compare the outcomes of treating distal ureteral stone with Silodosin, an α1- A adrenergic blocker, versus without Silodosin. Materials and Methods: A total of 70 patients aged between 18 and 50 years, diagnosed with distal ureteral stone, were enrolled in the study, which took place at the Department of Urology, Dhaka Medical College, from October 2017 to March 2019. The patients were divided into two groups: Group A and Group B. Group A consisted of 35 patients who were instructed to drink 3 litres of water daily, while Group B received the same instruction and also received Silodosin 8 mg/day. The treatment duration was four weeks, during which patients were monitored weekly through history, serum creatinine levels, X-ray KUB, and ultrasonogram of KUB. The number of stone expulsions, duration of spontaneous stone passage through the ureter, analgesic dosages, and adverse effects were recorded. Results: The higher expulsion rate in Group B (91.4%) compared to Group A (71.4%) (P=0.031). The mean expulsion duration was significantly shorter in Group B (8.94±3.58 days) compared to Group A (13.08±7.26 days) (P&lt;0.00298). Additionally, Group B required significantly lower analgesic dosages (115.71±75.51 mg) compared to Group A (255.71±108.31 mg) (P=0.00001). No adverse effects were observed in Group A, while two patients in Group B experienced adverse effects (retrograde ejaculation and postural hypotension). Conclusion: These results indicate that 8 mg/day of silodosin facilitates the expulsion of distal ureteral stone of about 5 to 10 mm in diameter in the largest dimension and significantly reduces the number of analgesic dosages.

Non-pharmacological and drug treatment of autonomic dysfunction in multiple system atrophy: current status and future directions.

Multiple system atrophy (MSA) is a sporadic, fatal, and rapidly progressive neurodegenerative disease of unknown etiology that is clinically characterized by autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs in any combination. Early onset and extensive autonomic dysfunction, including cardiovascular dysfunction characterized by orthostatic hypotension (OH) and supine hypertension, urinary dysfunction characterized by overactive bladder and incomplete bladder emptying, sexual dysfunction characterized by sexual desire deficiency and erectile dysfunction, and gastrointestinal dysfunction characterized by delayed gastric emptying and constipation, are the main features of MSA. Autonomic dysfunction greatly reduces quality of life and increases mortality. Therefore, early diagnosis and intervention are urgently needed to benefit MSA patients. In this review, we aim to discuss the systematic treatment of autonomic dysfunction in MSA, and focus on the current methods, starting from non-pharmacological methods, such as patient education, psychotherapy, diet change, surgery, and neuromodulation, to various drug treatments targeting autonomic nerve and its projection fibers. In addition, we also draw attention to the interactions among various treatments, and introduce novel methods proposed in recent years, such as gene therapy, stem cell therapy, and neural prosthesis implantation. Furthermore, we elaborate on the specific targets and mechanisms of action of various drugs. We would like to call for large-scale research to determine the efficacy of these methods in the future. Finally, we point out that studies on the pathogenesis of MSA and pathophysiological mechanisms of various autonomic dysfunction would also contribute to the development of new promising treatments and concepts.

Natural History and Phenotypic Spectrum of GAA-FGF14 Sporadic Late-Onset Cerebellar Ataxia (SCA27B).

Heterozygous GAA expansions in the FGF14 gene have been related to autosomal dominant cerebellar ataxia (SCA27B-MIM:620174). Whether they represent a common cause of sporadic late-onset cerebellar ataxia (SLOCA) remains to be established. To estimate the prevalence, characterize the phenotypic spectrum, identify discriminative features, and model longitudinal progression of SCA27B in a prospective cohort of SLOCA patients. FGF14 expansions screening combined with longitudinal deep-phenotyping in a prospective cohort of 118 SLOCA patients (onset >40 years of age, no family history of cerebellar ataxia) without a definite diagnosis. Prevalence of SCA27B was 12.7% (15/118). Higher age of onset, higher Spinocerebellar Degeneration Functional Score, presence of vertigo, diplopia, nystagmus, orthostatic hypotension absence, and sensorimotor neuropathy were significantly associated with SCA27B. Ataxia progression was ≈0.4 points per year on the Scale for Assessment and Rating of Ataxia. FGF14 expansion is a major cause of SLOCA. Our natural history data will inform future FGF14 clinical trials. © 2023 The Authors.

The mechanism of impaired delayed recall verbal memory function in Parkinson's disease with orthostatic hypotension: a multiple imaging study.

Orthostatic hypotension (OH) frequently accompanies autonomic dysfunction and is an important risk factor for cognitive impairment in Parkinson's disease (PD). However, the association between different cognitive functions and OH in PD patients is not yet fully understood. This study aimed to evaluate the scores of different cognitive domains and multiple parameters using different imaging techniques on PD patients with or without OH. A total number of 31 PD patients with OH (n = 20) and without OH (n = 11) were recruited from the Department of Neurology, Beijing Xuanwu Hospital for this study. All patients underwent beat-to-beat non-invasive blood pressure recordings and an active standing test to evaluate neurogenic OH and a global neuropsychological test to assess cognitive function. All patients underwent dynamic cerebral autoregulation (dCA) measurement, brain magnetic resonance imaging (MRI), and brain 18fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). The results showed that OH patients had poor delayed recall verbal memory when compared with the PD patients without OH (1.75 ± 1.59 vs. 3.10 ± 1.73, p = 0.042). The dCA test indicated a significant difference in the right very low-frequency (VLF) gain between two groups (1.27 ± 0.17 vs. 1.10 ± 0.26, p = 0.045) and the brain 18F-FDG PET/CT indicated a significant difference in the SUV (right medial temporal lobe) to SUV (occipital lobe) ratio (0.60 ± 0.08 vs. 0.67 ± 0.11, p = 0.049). Meanwhile, these two imaging parameters were negatively correlated (p < 0.001). Furthermore, the score of a delayed recall verbal memory in the OH group was positively correlated with the right medial temporal lobe to occipital lobe ratio (p < 0.001) and was negatively correlated with the right VLF gain (p = 0.023). PD with OH patients had poor delayed recall memory, which might have been caused by the decreased metabolic dysfunction of specific medial temporal lobe due to the impaired dCA ability.

Clinical manifestations of peripheral vegetative insufficiency in children and adolescents with type 1 diabetes mellitus (retrospective and prospective investigations)

The variety of complications of type 1 diabetes mellitus (DM) in children and adolescents are often observed in clinical practice. Among them, damage to the central and peripheral nervous system prevails. The term «peripheral vegetative insufficiency» (PVI) refers to a complex of vegetative manifestations that occur in the peripheral (segmental) part of the VNS against the DM background.&#x0D; Objective — to determine the clinical typology of PVN in children with type 1 DM during the period of the years 1980—1990 (retrospective investigation) and in the period of the years 2012—2022 (prospective study).&#x0D; Materials and methods. The study was conducted on the basis of the Department of Endocrinology of the SI «Institute of Child and Adolescent Health of the NAMS of Ukraine». Examinations involved 605 pediatric patients: 285 patients (126 children and 159 adolescents) in the retrospective study, and 320 subjects (186 children and 134 adolescents) in the group of prospective study. All patients underwent somatic, neurological, and clinical examinations.&#x0D; Results and discussion. It haі been determined that in children and adolescents with type 1 diabetes mellitus, PVI clinical manifestations were present in all physiological body systems and often occur under the mask of various somatic diseases. The most typical PVI clinical syndromes in pediatric patients with DM included orthostatic hypotension, tachycardia at rest, hypohidrosis, gastroparesis, constipation, and urinary incontinence. The incidence of PVI syndromes in the groups of patients in the prospective study (years 2012-2022) was lower than in the retrospective study (years 1980—1990) owing to the use of the novel technologies for the DM treatment.&#x0D; Conclusions. The labile, severe course of type 1 diabetes mellitus in children often triggers the development of autonomic disorders, which are predictors and manifestations of neurological disorders. As the overall duration of the disease increases and carbohydrate metabolism is not compensated properly, the number of functional organic neurological complications increases. Damage to immature brain structures affects their further development and forms the basis for the long-term neurological complications in older age.

Early-onset hereditary isolated non-neurogenic orthostatic hypotension in a Swedish family

PurposeOrthostatic hypotension is a common condition with heterogeneous and, in many cases, unclear underlying pathophysiology. Frequent symptoms are syncope and falls with a strong impact on daily life. A two-generation family with eight individuals segregating early-onset severe orthostatic hypotension with persistent tachycardia in upright position and repeated faints was identified. Our aim was to elucidate the underlying pathophysiology.MethodsOne severely affected individual underwent thorough investigation with neurophysiological and blood pressure (BP) measurements, including direct recording of baroreflex-governed sympathetic nerve signalling and induction of BP rise with phenylephrine. Family members underwent parts of the examination. Genetic analysis using exome sequencing was performed.ResultsMarked postural hypotension with greatly reduced cardiac preload was observed, but without signs of autonomic nervous system dysfunction: sympathetic nerve signalling was normal, as were catecholamine levels, and phenylephrine stimulation revealed a normal increase in BP. The results of the genetic analysis using exome sequencing comprising all known genes associated with the regulation of BP and catecholamine metabolism were normal.ConclusionThe combined findings suggest an autosomal dominant form of early-onset orthostatic hypotension with variable clinical expression and without any additional autonomic dysfunction. It is possible that further investigation will reveal an as yet undescribed entity of orthostatic hypotension transmitted as an autosomal dominant trait.

Development and Validation of a Prognostic Model to Predict Overall Survival in Multiple System Atrophy.

Multiple system atrophy (MSA) is a devastating disease characterized by a variable combination of motor and autonomic symptoms. Previous studies identified numerous clinical factors to be associated with shorter survival. To enable personalized patient counseling, we aimed at developing a risk model of survival based on baseline clinical symptoms. MSA patients referred to the Movement Disorders Unit in Innsbruck, Austria, between 1999 and 2016 were retrospectively analyzed. Kaplan-Meier curves and multivariate Cox regression analysis with least absolute shrinkage and selection operator penalty for variable selection were performed to identify prognostic factors. A nomogram was developed to estimate the 7 years overall survival probability. The performance of the predictive model was validated and calibrated internally using bootstrap resampling and externally using data from the prospective European MSA Study Group Natural History Study. A total of 210 MSA patients were included in this analysis, of which 124 patients died. The median survival was 7 years. The following clinical variables were found to significantly affect overall survival and were included in the nomogram: age at symptom onset, falls within 3 years of onset, early autonomic failure including orthostatic hypotension and urogenital failure, and lacking levodopa response. The time-dependent area under curve for internal and external validation was >0.7 within the first 7 years of the disease course. The model was well calibrated showing good overlap between predicted and actual survival probability at 7 years. The nomogram is a simple tool to predict survival on an individual basis and may help to improve counseling and treatment of MSA patients.

Postural fall in systolic blood pressure is a useful warning sign in dengue fever

Background: Capillary leak is the hallmark of development of severe dengue. A rise in haematocrit has been a major warning sign in WHO guidelines. Postural hypotension, which could reflect the intravascular volume reduction in capillary leak has been noted as warning sign in CDC and Pan American Health Organisation guidelines. We evaluated the diagnostic accuracy of postural hypotension as a marker of development of severe dengue. Methods: 150 patients admitted with dengue fever were recruited in this prospective observational study. Diagnostic accuracy of conventional warning signs (abdominal pain, persistent vomiting, fluid accumulation, mucosal bleeding, lethargy, liver enlargement, increasing hematocrit with decreasing platelets) and postural hypotension was evaluated. Results: 23 (15.3%) subjects developed severe dengue. Multiple logistic regression analysis showed that ascites/pleural effusion and postural fall in systolic blood pressure of &gt;10.33% had odds ratio of 5.024(95%CI:1.11 – 22.75) and 11.369 (95% CI:2.27 – 56.87), respectively. Other parameters did not reach statistical significance. Sensitivity and specificity of ascites/pleural effusion were 82.6% and 88.2% for development of severe dengue whereas postural fall in systolic blood pressure had sensitivity and specificity of 87% and 82.7%. Conclusions: These findings present a strong case for including postural hypotension as a warning sign in patients with dengue fever, especially in resource limited settings.

Semisitting position for cerebello-pontine angle surgery: Analysis of complications and how to avoid it

ObjectiveTo analyze the primary complications related to semisitting position in patients undergoing cerebelo-pontine angle surgery. MethodsRetrospective data analysis from patients undergoing elective tumoral cerebelo-pontine angle surgery in a semisitting position. The incidence, severity, occurrence moment, treatment, duration, and outcomes of venous air embolism (VAE), pneumocephalus, postural hypotension, and other complications were recorded. Neurointensive care unit (NICU), length of stay (LOS), hospital LOS, and modified Rankin scale scores were calculated six months after surgery. ResultsFifty patients were operated on. Eleven (22%) presented VAE (mean duration 8±4.5min): five (10%) during tumor resection, and four (8%) during dural opening. Ten (20%) were resolved by covering the surgical bed, air bubbles aspiration, jugular compression, and one (2%) tilted to a steep Trendelenburg position. One (2%) had intraoperative hemodynamic instability. The only variable associated with VAE was meningioma at histopathology OR=4.58, p=0.001. NICU was higher in patients with VAE (5.5±1.06 vs. 1.9±0.20 days, p=0.01). There were no differences in the Rankin scale. All patients presented postoperative pneumocephalus with a good level of consciousness, except one (2%) who required evacuation. Seven patients (14%) showed postural hypotension, three (6%) after positioning, and one (2%) after developing a VAE; all were reversed with usual vasoactive drugs. No other position-related complications or mortality were registered in this series. ConclusionsThe semisitting position is a safe option with the knowledge, prevention, detection, and early solution of all the possible complications. The development of VAE rarely implies hemodynamic instability or greater disability after surgery. Postoperative pneumocephalus is very common and rarely requires evacuation. Excellent cooperation between anesthesia, nursing, neurophysiology, and neurosurgery teams is essential to manage complications.

The Implementation of Renal Denervation in the Management of Resistant Hypertension Despite Use of Multitherapy Antihypertensives at Maximally Tolerated Doses: A Contemporary Literature Review.

Refractory hypertension is highly prevalent among the hypertensive population, and current clinical management has failed to provide optimal control for these individuals. This subtype of arterial hypertension is defined as a persistently elevated systolic blood pressure reading of 140 mmHg, or higher, despite multiple antihypertensive use at maximally tolerated dosing. These patients have an elevated risk of cardiovascular and renal complications, urging for the need of more effective therapeutic management. Renal sympathetic efferent nerves have been noted to play an important role in volume and blood pressure homeostasis. Before the implementation of oral antihypertensives, the use of surgical lumbar sympathectomy for the reduction of persistent hypertension was considered a life-saving approach. However, individuals were left with debilitating side effects, such as postural hypotension, syncope, and impotence. A new and minimally invasive technique has been proposed, where the kidneys undergo selective denervation in hopes of providing decreased cardiovascular morbidity and mortality for patients with resistant hypertension. Some studies demonstrated promising outcomes with a reduction in blood pressure, a decrease in medication reliance, and a potential long-lasting effect of the procedure with an overall improvement in cardiovascular health. Unfortunately, most of the available data was obtained from observational, uncontrolled studies with short-term follow-up, small sample sizes, and high variability in blood pressure measurement. Therefore, further evidence is needed to determine whether renal denervation provides long-term benefits for blood pressure control and improves outcomes for mortality and cardiovascular events in this patient population.

Persistent Orthostatic Hypotension Following Surgery for Adult Spinal Deformity: Prevalence, Risk Factors, and Cardiovascular Evaluation.

Retrospective case-control study. To understand the prevalence of persistent orthostatic hypotension (POH), as well as its risk factors and cardiovascular pathology, in patients receiving surgery for the adult spinal deformity (ASD). Although reports of the incidence of and risk factors for POH in different spinal disorders have recently been published, we are not aware of the comprehensive evaluation of POH following surgery for ASD. We examined medical records from a single central database for 65 patients receiving surgical treatment for ASD. Statistical comparisons were made between patients who experienced postoperative POH and those who did not, by examining patient and operative characteristics, such as age, sex, comorbidities, functional status, preoperative neurological function, vertebral fractures, three-column osteotomy, total operative time, estimated blood loss, length of stay, and radiographic parameters. The determinants of POH were assessed using multiple logistic regression. We showed that postoperative POH was a complication of ASD surgery, with a 9% incidence rate. Patients with POH were statistically considerably more likely to require supported walkers due to partial paralysis and to have comorbidities including diabetes and neurodegenerative disease (ND). Furthermore, ND was an independent risk factor for postoperative POH (odds ratio, 4.073; 95% confidence interval, 1.094-8.362; p =0.020). Moreover, perioperative evaluation of the inferior vena cava showed that patients with postoperative POH had preoperative congestive heart failure and had hypovolemia lower postoperative diameter of the inferior vena cava than patients without POH. Postoperative POH is a potential complication of ASD surgery. The most pertinent risk factor is having an ND. According to our study, patients who have surgery for ASD may experience alterations in their hemodynamics.

Understanding Measurement of postural hypotension: a nationwide survey of primary care practice in England.

Postural hypotension (PH), the drop in blood pressure (BP) on standing, is associated with falls, all-cause mortality and cognitive decline. PH diagnostic criteria require lying-to-standing BP measurements. PH Prevalence in older adults is 20%, however, it is infrequently recorded in primary care records, suggesting PH testing and/or recording is under-utilised in this setting. To understand current PH measurement and management by primary care practitioners in England. Clinical Research Networks circulated an online survey to primary care clinicians involved in measurement of BP. Demographics and responses were summarised as percentages, or median and inter-quartile ranges (IQR), as appropriate. The survey remains open until 30 November 2022; full results will be presented at the conference. To date, there are 669 replies (341 doctors, 179 nurses, 70 healthcare assistants, 23 pharmacists, 56 other roles); median age 45 (IQR 38 to 53), 72% female. Overall, 597 (89%) responders check for PH, predominantly when symptoms are present (98%). Less common reasons to check include patients being over 80 (24%), Parkinson's disease (21%), hypertension reviews (18%), medication reviews (12%) or diabetes reviews (11%). Sitting-to-standing BP measurements are common (77%); only 22% use lying-to-standing. Only 64% ensure a rest period before sitting or lying BP measurement and only 1 (IQR 1 to 2) standing BP measurement is made, usually (66%) within the first minute of standing. Interim findings suggest that most PH assessments in primary care do not meet current guideline criteria. Full findings from this survey are expected to inform and influence future national guidelines.

Effects of different levodopa doses on blood pressure in older patients with early and middle stages of Parkinson's disease

ObjectiveLevodopa is the first-line treatment for patients with Parkinson's disease (PD). However, only a few studies have focused on the tolerance of this drug in older patients with PD in the early and middle stages. Therefore, this study aimed to explore the effects of different levodopa doses on blood pressure (BP) in this subpopulation. MethodsThis cohort analysis enrolled 83 patients. The levodopa challenge test was used to evaluate drug responsiveness. After at least 12 h following anti-PD drug discontinuation, patients’ BPs were measured in a lying position, after 1 min standing, and after 3 min standing, in “off state” and best “on state.” ResultsBP in the 250 mg and 375 mg levodopa/benserazide groups decreased significantly in the lying and standing positions. The 3-min standing-position systolic BP was significantly influenced by the dose of levodopa/benserazide. However, no statistical change was observed in the 125 mg group. The postural-mediated systolic BP disparity was significant at 3 min in the upright position. Nineteen (incidence, 22.9%) and Twenty-five patients (incidence, 30.1%) developed complications of orthostatic hypotension (OH) in the “off state” and best “on state,” respectively. Mild cognitive impairment was a risk factor for OH occurrence in the “off state.” The OH occurrence in the best “on state” was associated with OH in the “off state” and urinary incontinence. ConclusionOur findings suggest that 250 mg or more of levodopa/benserazide could significantly reduce BP and orthostatic effect in older patients with PD in the early and middle stages. Therefore, they should routinely monitor their BP. Trial registration numberChiCTR2200055707.

A Case Report of Dizziness with Postural Hypotension Improved by Korean Medicine Treatment

Background: Postural hypotension refers to a drop in systolic blood pressure of 20 mmHg or diastolic blood pressure of 10 mmHg or more within three minutes after standing up from lying down. Symptoms of postural hypotension not only include dizziness and blurred vision but also fatigue, cognitive decline, leg weakness, headache, and, in severe cases, fainting. Postural hypotension is a phenomenon that occurs in about 6% of the total population, and in Korea, the number of patients with postural hypotension is continuously increasing. Both pharmacological and non-drug therapies, which are treatment methods for this disease, do not show a satisfactory symptom improvement effect.Case summary: A 65-year-old male patient who visited the hospital complaining of dizziness and paresthesia due to postural hypotension was treated with acupuncture, moxibustion, and herbal medicine. For symptom evaluation, the numeric rating scale (NRS) of each symptom was used, and blood pressure change according to posture was measured. After treatment, the NRSs of dizziness and dysesthesia were decreased, and blood pressure changes according to posture was improved.Conclusion: This case report suggests that Korean medicine treatment, including acupuncture, electro-acupuncture, moxibustion, and herbal medicine, can be an effective treatment for dizziness with postural hypotension.

MİTRAL KAPAK PROLAPSUSU OLAN ÇOCUKLARDA KARDİYAK OTONOMİK DİSFONKSİYONUN VE ARİTMİ RİSKİNİN DEĞERLENDİRİLMESİ

Objective: The occurrence of symptoms in patients with mitral valve prolapse (MVP) is linked to autonomic dysfunction and neuroendocrine causes rather than progressive mitral valve insufficiency. The goal was to assess the risk of autonomic dysfunction and arrhythmia in patients with MVP.&#x0D; Methods: The study included 63 patients with primary MVP and a control group of 64 children of similar age and gender. Following a physical examination, all patients' histories were taken, and 12-lead ECGs, autonomic function tests, echocardiography, and 24-hour Holter rhythm studies were performed.&#x0D; Results: The patient group had a higher mean resting heart rate than the control group. Orthostatic hypotension was found in 8 patients (12.6%) and 4 children (6.2%) in the control group. When compared to the control group, patients with MVP had higher QTc dispersion, frontal QRS-T angle, Tp-e interval, and Tp-e/QTc ratio. There was no significant difference between the two groups in terms of conventional measurements of heart rate variability in the Holter ECG, as well as no significant difference in HRDC.&#x0D; Conclusion: Although cases with pathological findings in the initial ECG were excluded from our study, we believe that the high frontal QRS-T angle observed in MVP patients is a novel and significant finding. Furthermore, it has been discovered that HRDC, a new and understudied parameter in children, does not show a significant difference in patients with MVP.

The cardiovascular mononeuropathy in Hemodialysis Patients analysed by a combination with reactivity tests to noninvasively evaluate skin sympathetic nerve activity and skin microvascular function by (LDF)

Aim: Although several patients with kidney disease have simultaneous dysfunction of the parasympathetic and sympathetic nervous systems, orthostatic hypotension during a hemodialysis (HD) procedure impacts not only the form of treatment but overall comfort of life for patients with HD. Despite a number of methods that are not invasive and have already been used to assess autonomous functioning, a system for monitoring malfunction throughout filtration of blood therapy which has yet to be discovered. Methods: Regarding the purpose of monitoring the autonomous function of stable 40 regular HD patients and 35 healthy controls, we examined the clinical application of the laser-Doppler blood flow meter (LDF). By detecting the periflux blood flow decreasing velocity (PDV) while combined with the Valsalva manoeuvre, the LDF device which was used for an autonomous test. We also looked at the relationship between PDV and traditional atherosclerosis testing. Results: The baseline PDV (5.30 ± 2.93), comparative to subjects who were in excellent condition (9.65 ± 7.10), was substantially decreased in the HD populace. Furthermore, we discovered a substantial connection between PDV and established parameters like heart rate fluctuation and ankle-brachial blood pressure indexing. Conclusion: Regarding assessing autonomous functioning in hemodialysis patients, evaluation of PDV by LDF is just as effective as the standard approach. The benefit from regular and recurring assessments of autonomous dysfunction is made possible by the device's ease.
