One-year outcomes following a hypertensive urgency or emergency.

There are scarce data on the comparative prognosis between patients with hypertensive emergencies (HE), urgencies (HU), and those without HU or HE (HP). Our study aimed to compare cardiovascular (CV) outcomes of HE, HU, and HP during a 12-month follow-up period. The population consisted of 353 consecutive patients presenting with HE or HU in a third-care emergency department and subsequently referred to our hypertension center for follow-up. After both groups completed scheduled follow-up visits, patients with HU were matched one-to-one by age, sex, and hypertension history with HP who attended our hypertension center during the same period. Primary outcomes were 1) a recurrent hypertensive HU or HE event and 2) non-fatal CV events (coronary heart disease, stroke, heart failure, or CV interventions), while secondary outcomes were 1) all-cause death, 2) CV death, 3) non-CV death, and 4) any-cause hospitalization. Events were prospectively registered for all three groups. During the study period, 81 patients were excluded for not completing follow-up. Among eligible patients(HE = 94; HU = 178), a total of 90 hospitalizations and 14 deaths were recorded; HE registered greater CV morbidity when compared with HU (29 vs. 9, HR 3.43, 95 % CI 1.7-6.9, p = 0.001), and increased CV mortality (8 vs. 1, HR 13.2, 95 % CI 1.57-110.8, p = 0.017). When opposing HU to HP, events did not differ substantially. Cox regression models were adjusted for age, sex, CV and chronic kidney disease, diabetes mellitus, and smoking. During 1-year follow-up, the prognosis of HU was better than HE but not different compared to HP. These results highlight the need for improved care of HU and HE.

Hypertensive Emergencies: Implications for Nurses.

An acute elevation of blood pressure (BP) greater than 180/120 mm Hg associated with target organ damage is considered a hypertensive emergency. Patients with a hypertensive emergency need intravenous medications and close monitoring in the intensive care unit. Whereas an acute elevation of BP greater than 180/120 mm Hg without evidence of target organ damage is a hypertensive urgency. Patients with a hypertensive urgency are treated with oral medications and generally discharged home with outpatient follow-up. Patients with either condition need a thorough evaluation to determine cause of the acute increase in BP and education to optimize the treatment regimen long-term.

A Systematic Review and Meta-analysis of the Clinical and Epidemiological Characteristics of Patients with Hypertensive Emergencies: Implication for Risk Stratification.

INTRODUCTION: Acute severe elevation of blood pressure (BP) is a common clinical event, that can present as hypertensive emergency (HTNE) and hypertensive urgency (HTNU). HTNE results in life-threatening target organ damage, including myocardial infarction, pulmonary edema, stroke, and acute kidney injury. It is associated with high utilization of healthcare and increased cost. HTNU is high BP without acute serious complications. AIM: The purpose of this review was to examine the clinical-epidemiological characteristics of patients with HTNE and propose a risk stratification framework to differentiate between the two conditions, since prognosis, setting of therapy and treatment is vastly different. METHODS: Systematic review. RESULTS: Fourteen full-text studies were included in this review. In comparison with HTNU, patients with HTNE had higher mean systolic (mean difference 2.413, 95% CI 0.477, 4.350) and diastolic BP (mean difference 2.043, 95% CI 0.624, 3.461). HTNE were more prevalent in men (OR 1.390, 95% CI 1.207, 1.601), older adults (mean difference 5.282, 95% CI 3.229, 7.335) and those with diabetes (OR 1.723, 95% CI 1.485, 2.000). Non-adherence to BP medications (OR 0.939, 95% CI 0.647, 1.363) and unawareness of hypertension diagnosis (OR 0.807, 95% CI 0.564, 1.154) did not elevate the risk of HTNE. CONCLUSIONS: Systolic and diastolic BP are marginally higher in patients with HTNE. Given that these differences are not clinically significant, other epidemiological and medical characteristics (older age, male sex, cardiometabolic comorbidities) as well as patient's presentation should be considered to differentiate between HTNU and HTNE.

Impact of early initiation of renin-angiotensin blockade on renal function and clinical outcomes in patients with hypertensive emergency: a retrospective cohort study.

BACKGROUND: Hypertensive emergency is a critical disease that causes multifaceted sequelae, including end-stage kidney disease and cardiovascular disease. Although the renin-angiotensin-aldosterone (RAA) system is enormously activated in this disease, there are few reports that attempt to characterize the effect of early use of RAA inhibitors (RASi) on the temporal course of kidney function. METHODS: This retrospective cohort study was conducted to clarify whether the early use of RASi during hospitalization offered more favorable benefits on short-term renal function and long-term renal outcomes in patients with hypertensive emergencies. We enrolled a total of 49 patients who visited our medical center with acute severe hypertension and multiple organ dysfunction between April 2012 and August 2020. Upon admission, the patients were treated with intravenous followed by oral antihypertensive drugs, including RASi and Ca channel blockers (CCB). Kidney function as well as other laboratory and clinical parameters were compared between RASi-treated and CCB- treated group over 2 years. RESULTS: Antihypertensive treatment effectively reduced blood pressure from 222 ± 28/142 ± 21 to 141 ± 18/87 ± 14 mmHg at 2 weeks and eGFR was gradually restored from 33.2 ± 23.3 to 40.4 ± 22.5 mL/min/1.73m2 at 1 year. The renal effect of antihypertensive drugs was particularly conspicuous when RASi was started in combination with other conventional antihypertensive drugs at the early period of hospitalization (2nd day [IQR: 1-5.5]) and even in patients with moderately to severely diminished eGFR (< 30 mL/min/1.73 m2) on admission. In contrast, CCB modestly restored eGFR during the observation period. Furthermore, renal survival probabilities were progressively deteriorated in patients who had manifested reduced eGFR (< 15 mL/min/1.73 m2) or massive proteinuria (urine protein/creatinine ≥ 3.5 g/gCr) on admission. Early use of RASi was associated with a favorable 2-year renal survival probability (0.90 [95%CI: 0.77-1.0] vs. 0.63 [95%CI: 0.34-0.92] for RASi ( +) and RASi (-), respectively, p = 0.036) whereas no apparent difference in renal survival was noted for CCB. CONCLUSIONS: Early use of RASi contributes to the renal functional recovery from acute reduction in eGFR among patients with hypertensive emergencies. Furthermore, RASi offers more favorable effect on 2-year renal survival, compared with CCB.

Hypertensive emergencies and urgencies: a preliminary report of the ongoing Italian multicentric study ERIDANO.

Hypertensive urgencies (HU) and hypertensive emergencies (HE) are challenges for the Emergency Department (ED). A prospective multicentre study is ongoing to characterize patients with acute hypertensive disorders, prevalence of subclinical hypertension-mediated organ damage (HMOD), short- and long-term prognosis; this is a preliminary report. Patients admitted to the ED with symptomatic blood pressure (BP) ≥180/110 mmHg were enrolled. They were managed by ED personnel according to their clinical presentations. Subsequently they underwent clinical evaluation and subclinical HMOD assessment at a Hypertension Centre within 72 h from enrolment. 122 patients were included in this report. Mean age was 60.7±13.9 years, 52.5% were females. 18 (14.8%) patients were diagnosed with HE, 108 (88.5%) with HU. There were no differences in gender, BMI, and cardiovascular comorbidities between groups. At ED discharge, 66.7% and 93.6% (p = 0.003) of HE and HU patients, respectively, had BP < 180/110 mmHg. After 72 h, 34.4% of patients resulted normotensive; 35.2%, 22.1%, and 8.2% had hypertension grade 1, 2, and 3, respectively. Patients with uncontrolled BP at office evaluation had higher vascular HMOD (49.1 vs. 25.9%, p = 0.045). Cardiac (60 vs. 34%, p = 0.049), renal (27.8 vs. 9.6%, p = 0.010) and cerebral (100 vs. 21%, p < 0.001) HMOD was more frequent in HE compared to HU group. HE showed greater cardiac, renal, and cerebral subclinical HMOD, compared to HU. 72-hours BP control is not associated with different HMOD, except for vascular HMOD; therefore, proper comprehensive examination after discharge from the ED could provide added value in cardiovascular risk stratification of such patients. One third of patients with acute blood pressure rise evaluated to the ED resulted normotensive at office evaluation (<72 hours after discharge). Patients with hypertensive emergency showed greater cardiac, renal, and cerebral subclinical HMOD, compared to the patients with hypertensive urgency. BP: blood pressure; HMOD: hypertension-mediated organ damage; y.o.: years old; mo.: months.

Patient care during interfacility transport: a narrative review of managing diverse disease states.

BACKGROUND: When critically ill patients require specialized treatment that exceeds the capability of the index hospitals, patients are frequently transferred to a tertiary or quaternary hospital for a higher level of care. Therefore, appropriate and efficient care for patients during the process of transport between two hospitals (interfacility transfer) is an essential part of patient care. While medical adverse events may occur during the interfacility transfer process, there have not been evidence-based guidelines regarding the equipment or the practice for patient care during transport. METHODS: We conducted searches from the PubMed, Cumulative Index of Nursing and Allied Health (CINAHL), and Scopus databases up to June 2022. Two reviewers independently screened the titles and abstracts for eligibility. Studies that were not in the English language and did not involve critically ill patients were excluded. RESULTS: The search identified 75 articles, and we included 48 studies for our narrative review. Most studies were observational studies. CONCLUSION: The review provided the current evidence-based management of diverse disease states during the interfacility transfer process, such as proning positioning for respiratory failure, extracorporeal membrane oxygenation (ECMO), obstetric emergencies, and hypertensive emergencies (aortic dissection and spontaneous intracranial hemorrhage).

Emergencies in obstetric anaesthesia: a narrative review.

We conducted a narrative review in six areas of obstetric emergencies: category-1 caesarean section; difficult and failed airway; massive obstetric haemorrhage; hypertensive crisis; emergencies related to neuraxial anaesthesia; and maternal cardiac arrest. These areas represent significant research published within the last five years, with emphasis on large multicentre randomised trials, national or international practice guidelines and recommendations from major professional societies. Key topics discussed: prevention and management of failed neuraxial technique; role of high-flow nasal oxygenation and choice of neuromuscular drug in obstetric patients; prevention of accidental awareness during general anaesthesia; management of the difficult and failed obstetric airway; current perspectives on the use of tranexamic acid, fibrinogen concentrate and cell salvage; guidance on neuraxial placement in a thrombocytopenic obstetric patient; management of neuraxial drug errors, local anaesthetic systemic toxicity and unusually prolonged neuraxial block regression; and extracorporeal membrane oxygenation use in maternal cardiac arrest.

Anesthetic considerations for inadvertent severe hypertension in a patient with osteogenesis imperfecta during the perioperative period.

Osteogenesis imperfecta is a rare genetic syndrome caused by mutations of bone matrix protein type I collagen coding genes, which is characterized by increased bone fragility and recurrent fractures. We report a patient undergoing general anesthesia with additional nerve block for wrist and hip fracture repair. Preoperatively, we were confronted with an inadvertent severe hypertension without significant triggers and history, which prompted us to be vigilant for hypertensive emergencies due to the fragile vessel regulation capacity in osteogenesis imperfecta patients.

Rationale for the Concept of Impending Hypertension-Mediated Organ Damage.

BACKGROUND: The number of patients with hypertension urgencies (HTN-Us) and emergencies (HTN-Es) in the emergency department is relatively constant despite improved detection, awareness and control of arterial hypertension. OBJECTIVE: This study analyses the precision of the often-used definition of HTN-E, particularly the phrase 'with the evidence of impending or progressive hypertension-mediated organ damage (HMOD)'. We then provide a rationale for the concept of impending HMOD. METHODS: The databases PubMed, Science Direct, Springer, Oxford Press, Wiley, SAGE and Google Scholar were searched and the relevant definition has been analyzed. RESULTS: The definition of HTN-E is suboptimal and requires a consensus on whether to include the phrase 'impending hypertensive HMOD' in the definition. CONCLUSION: A consensus on the principles of treating the 'impending hypertensive HMOD' does not exist, making its use inconsistent in emergency departments worldwide. In this paper, we present a rationale for the concept of 'impending HMOD'.

Modern Management of Hypertensive Emergencies.

Acute increases of blood pressure values are common causes of patients' presentation to emergency departments, and their management represents a clinical challenge. They are usually described as 'hypertensive crises', 'hypertensive urgencies', terms that should be abandoned because they are misleading and inappropriate according to a recent task force of the European Society of Cardiology, which recommended to focus only on 'hypertensive emergencies'. The latter can be esasily identified by using the Brain, Arteries, Retina, Kidney, and/or Heart (BARKH) strategy as herein described. Although current guidelines recommendations/suggestions for treatment of these patients are not evidence-based, owing to the lack of randomized clinical trials, improved understanding of the underlying pathophysiology has changed the approach to management of the patients presenting with hypertensive emergencies in recent years. Starting from these premises and a systematic review of the available studies graded by their quality, using the AHA class of recommendation/level of evidence grading, whenever possible, we herein present a novel a streamlined symptoms- and evidence-based algorithm for the assessment and management of patients with hypertensive emergencies.

Profile and management of hypertensive urgencies and emergencies in the emergency cardiology department of a tertiary hospital: a 12-month registry.

AIMS: Currently there are scarce epidemiological data regarding prevalence, clinical phenotype, and therapy of hypertensive urgencies (HU) and emergencies (HE). The aim of this article was to record the prevalence, clinical characteristics, and management of patients with HU and HE assessed in an emergency department (ED) of a tertiary hospital. METHODS AND RESULTS: The population consisted of patients presenting with HE and HU in the ED (acute increase in systolic blood pressure (BP) ≥ 180 mmHg and/or diastolic BP ≥120 mmHg with and without acute target organ damage, respectively). Of the 38 589 patients assessed in the ED during a 12-month period, 353 (0.91%) had HU and HE. There were 256 (72.5%) cases presented as HU and 97 (27.5%) as HE. Primary causes for both HU and HE were stress/anxiety (44.9%), increased salt intake (33.9%), and non-adherence to medication (16.2%). Patients with HU reported mainly dizziness/headache (46.8%) and chest pain (27.4%), whereas those with HE presented dyspnoea (67%), chest pain (30.2%), dizziness/headache (10.3%), and neurological disorders (8.2%). In HE, the underlying associated conditions were pulmonary oedema (58%), acute coronary syndrome (22.6%), and neurological disorders/stroke (7.2%). All HE cases were hospitalized and received intensive healthcare, including dialysis. CONCLUSION: This 1-year single-centre registry demonstrates a reasonable prevalence of HU and HE contributing to the high volume of visits to the ED. Stress, increased salt intake and non-adherence were main triggers of HE and HU. Dizziness and headache were the prevalent symptoms of HU patients while heart failure was the most common underlying disease in patients with HE.

Pharmacotherapy for hypertensive urgency and emergency in COVID-19 patients.

INTRODUCTION: Hypertension is a common chronic disorder in patients hospitalized for coronavirus disease 2019 (COVID-19). Furthermore, an exaggerated cardiovascular response with persistently raised blood pressure during hospitalization seems independently associated with in-hospital all-cause mortality, intensive care unit admission and heart failure. However, the real burden of elevated blood pressure during the acute phase of COVID-19 remains undefined. AREAS COVERED: The authors review the available evidence on the pharmacotherapy for the treatment of acute elevations in blood pressure (including hypertensive urgency and emergency) in COVID-19 patients. EXPERT OPINION: Acute elevations in blood pressure and unstable in-hospital blood pressure may be associated with organ damage and worse outcome in patients with COVID-19. In this setting, hypertensive emergencies require immediate reduction in blood pressure through intravenous treatment according to specific features and goals. Conversely, hypertensive urgencies usually require solely oral treatment. Diuretics, beta-blockers, renin-angiotensin-aldosterone system inhibitors, and calcium channel blockers may be of benefit in treating COVID-19 patients with elevated blood pressure values.

Management of hypertensive emergencies: a practical approach.

Background: Acute increases of high blood pressure values, usually described as 'hypertensive crises', 'hypertensive urgencies' or 'hypertensive emergencies', are common causes of patients' presentation to emergency departments. Owing to the lack of ad hoc randomized clinical trials, current recommendations/suggestions for treatment of these patients are not evidenced-based and, therefore, the management of acute increases of blood pressure values represent a clinical challenge. However, an improved understanding of the underlying pathophysiology has changed radically the approach to management of the patients presenting with these conditions in recent years. Accordingly, it has been proposed to abandon the terms 'hypertensive crises' and 'hypertensive urgencies', and restrict the focus to 'hypertensive emergencies'. Aims and Methods: Starting from these premises, we aimed at systematically review all available studies (years 2010-2020) to garner information on the current management of hypertensive emergencies, in order to develop a novel symptoms- and evidence-based streamlined algorithm for the assessment and treatment of these patients.Results and Conclusions: In this educational review we proposed the BARKH-based algorithm for a quick identification of hypertensive emergencies and associated acute organ damage, to allow the patients with hypertensive emergencies to receive immediate treatment in a proper setting.

Predictors of clinically relevant differences between noninvasive versus arterial blood pressure.

OBJECTIVE: Blood pressure (BP) measurements are important for managing patients with hypertensive emergencies (HE). Previous studies showed that there was significant difference between IABP and NIBP but no information whether these differences changed management. Our study investigated the factors associated with the differences affecting BP management of patients with HE. METHODS: This was a retrospective study involving adult patients admitted to a resuscitation unit. We screened all patients who received IABP upon admission between 06/01/2017 and 12/31/2017 as sample size calculation recommended 64 patients. Primary outcome was the clinical relevance of the difference of IABP vs. NIBP, which was defined as having both: a) difference of 10 mm of mercury (mmHg), and b) resulting in possible change of blood pressure managements according to treatment guidelines. We performed backward stepwise multivariable logistic regression to measure associations. RESULTS: We analyzed 147 patients whose mean age was 69 (±16) years and included 69 (47%) patients with spontaneous intracerebral hemorrhage (sICH). Mean difference between IABP and NIBP was 21 (±16) mmHg while 41 (28%) patients who had difference affecting managements. In multivariable regression, sICH (Odd Ratios 13.5, 95%CI 2.3-79.5, p-value < 0.001) was significantly associated with clinically relevant difference between the two modalities of BP monitoring. CONCLUSIONS: There was a large difference between IABP and NIBP among patients with hypertensive emergencies. Up to 30% of patients had clinically relevant differences. Patients with sICH were more likely to have differences affecting BP management. Further studies are needed to confirm our observation.

Efectividad del tratamiento acupuntural en las urgencias hipertensivas durante el preoperatorio de cirugías menores / Effectiveness of Acupuncture against Hypertensive Emergencies during the Preoperative of Minor Surgeries

Introducción: Las urgencias hipertensivas constituyen una de las complicaciones agudas más frecuentes de la hipertensión arterial y es causa de muerte prematura entre adultos. Muchas publicaciones abogan por el uso de la Medicina Tradicional y Natural como método terapéutico eficaz e inocuo en su manejo. Objetivo: Evaluar la efectividad del tratamiento acupuntural en las urgencias hipertensivas durante el preoperatorio en los pacientes que serán sometidos a intervenciones quirúrgicas ambulatorias menores en el Hospital Clínico Quirúrgico Dr. Juan Bruno Zayas Alfonso, de enero a octubre de 2019. Métodos: Se efectuó un estudio de intervención terapéutica. El universo estuvo constituido por 150 pacientes hipertensos que fueron asignados aleatoriamente a un grupo estudio que recibió tratamiento con acupuntura y un grupo control que recibió tratamiento medicamentoso. A todos se les realizó diagnóstico occidental y oriental. Ambos grupos estuvieron conformados por 75 pacientes. Resultados: Predominó el grupo de edades de 45 a 54 años en ambos grupos, un mayor número de mujeres enfermas. El síntoma que más afectó al total de los pacientes fue la cefalea y hubo superioridad del diagnóstico síndrome hiperactividad de fuego de hígado. El 74 por ciento de los pacientes a los que se les aplicó acupuntura mejoraron y un 66 por ciento lo lograron en el grupo control. Conclusiones: El tratamiento acupuntural resultó ser efectivo en los pacientes con urgencias hipertensivas durante el preoperatorio para las intervenciones quirúrgicas ambulatorios menores(AU)

Introduction: Hypertensive emergencies are one of the most frequent acute complications of arterial hypertension and the cause of premature death among adults. Many publications advocate the use of traditional and natural medicine as an effective and safe therapeutic method for its management. Objective: To assess the effectiveness of acupuncture against hypertensive emergencies during the preoperative period in patients who will undergo minor outpatient surgical interventions at Dr. Juan Bruno Zayas Alfonso Clinical-Surgical Hospital, from January to October 2019. Methods: A therapeutic intervention study was carried out.

Medidas preventivas y manejo diagnóstico y terapéutico de la hipertensión arterial y las crisis hipertensivas / Preventive measures and diagnostic and therapeutic management of arterial hypertension and hypertensive crises

Introducción: La hipertensión arterial (HTA) es definida por algunos como una enfermedad, aunque también se la considera como factor de riesgo cardiovascular. Hoy conocemos como las enfermedades cardiovasculares dependen más de la influencia simultánea de varios factores de riesgo que de la acción aislada de uno de ellos. Por ello, toda actividad preventiva en este campo, debe ser multifactorial y dirigida en diversos sentidos. Desarrollo: Cuando la HTA no es controlada se triplica la probabilidad de accidente cerebrovascular e insuficiencia cardiaca, con menor incidencia de enfermedad coronaria y arterial periférica. El propio aumento de la masa del ventrículo izquierdo, así como los cambios estructurales que tienen lugar a nivel del miocardio y de los vasos coronarios pueden desencadenar episodios de cardiopatía isquémica. El remodelado intersticial y el aumento de la masa del ventrículo izquierdo son factores predisponentes a la aparición de arritmias ventriculares y muerte súbita. Es importante evaluar y tratar a los pacientes recién diagnosticados con HTA con medicamentos adecuados y seguimiento para prevenir la progresión de la hipertensión no controlada a crisis hipertensivas, es decir, urgencia o emergencia hipertensiva. Conclusiones: El reconocimiento inmediato de una emergencia hipertensiva con las pruebas de diagnóstico apropiadas conducirá a una reducción adecuada de la presión arterial, aliviando la incidencia de consecuencias negativas a los órganos diana. El tratamiento adecuado ayudará a aliviar la progresión de la enfermedad y mejorar los resultados a largo plazo.

Introduction: Hypertension (HT) is defined by some as a disease, although it is also considered a cardiovascular risk factor. Today we know cardiovascular diseases depend more on the simultaneous influence of several risk factors than on the isolated action of one of them. Therefore, all preventive activity in this field must be multifactorial and directed in various ways. Developing: When HT is not controlled, the probability of stroke and heart failure, with a lower incidence of coronary and peripheral arterial disease triples. The increase in left ventricular mass itself, as well as, the structural changes that occur at the level of myocardium and coronary vessels, can trigger episodes of ischemic heart diseases. Interstitial remodeling and increased left ventricular mass are predisposing factors to the appearance of ventricular arrhythmias and sudden death. It is important to evaluate and treat newly diagnosed patients with HT with recommended medications and follow-up to prevent the progression of uncontrolled HT to hypertensive crises, that is, urgency or emergency hypertension. Conclusion: The immediate recognition of a hypertensive emergency with the affected diagnostic tests will lead to an adequate reduction of blood pressure, alleviating the incidence of negative consequences to the target organs. Proper treatment helps to decrease the progression of the disease and improves long-term outcomes.

Accuracy of a Symptom-Based Approach to Identify Hypertensive Emergencies in the Emergency Department.

BACKGROUND: A hierarchical symptoms-based diagnostic strategy relying on the presence of five main symptoms (chest pain, acute dyspnea, neurological symptoms, headache, visual impairment) was recently proposed to diagnose patients with hypertensive emergency. However, poor scientific evidence is available about the role of symptoms in both diagnosis and management of acute hypertensive disorders. METHODS: Data from 718 patients presenting to the emergency department of the "Città della Salute e della Scienza" Hospital of Turin with systolic blood pressure > 180 and/or diastolic blood pressure > 110 mm/Hg were retrospectively analyzed. The accuracy of the typical symptoms for identification of hypertensive emergencies was assessed. RESULTS: A total of 79 (11%) out of 718 patients were diagnosed with hypertensive emergencies (51% had cardiovascular and 49% neurovascular acute organ damage). Patients with hypertensive emergencies were older and with higher prevalence of coronary artery disease and chronic heart failure than patients with uncontrolled hypertension. Typical symptoms could discriminate true hypertensive emergency from uncontrolled hypertension with 64% accuracy, 94% sensitivity, and 60% specificity. CONCLUSION: Typical symptoms might be used as a simple screening test (99% negative predictive value) in the emergency department to select for further evaluations of patients with suspected hypertensive emergencies among those with acute hypertensive disorders.
