Acute blood pressure elevation: Therapeutic approach

Neurological hypertensive emergencies: Correlation of blood pressure values with in-hospital outcomes in ischemic stroke

BACKGROUND

Few certainties exist regarding optimal management of Blood Pressure (BP) in the very first hours after an ischemic stroke and many questions remain still unanswered. Our work aimed to evaluate the role of BP and its trend as possible determinants of in-hospital mortality (primary outcome), discharge disabilities and hospitalization length (secondary outcomes) in ischemic stroke patients presented with Hypertensive Emergencies (HE).

METHODS

We retrospectively evaluated patients presented to Niguarda Hospital, Emergency Department (ED), from 2015 to 2017 with a neurological ischemic HE. BP at ED presentation (T0), its management in ED (T1) and its values at the stroke unit admission (T2) were evaluated.

RESULTS

267 patients were included (0.13 % of all ED accesses and 17.9 % of all ischemic strokes). In the whole population, BP values were not associated with in-hospital mortality while T0 and T2 SBP result were associated to discharge disability and hospitalization length. In pre-specified subgroup analysis these associations were confirmed only in untreated subjects (not anti-hypertensive nor thrombolysis). In fact, no significant relationship can be found between BP values and any secondary outcome in thrombolysis and anti-hypertensive treated patients.

CONCLUSIONS

BP values and its management can not be related to in-hospital mortality in stroke patients, presented with HE, while they are associated to discharge disability and hospitalization length. In subgroup analysis, results were confirmed only in untreated (not anti-hypertensive therapies nor thrombolytic).

Prediction of acute hypertensive episodes in critically ill patients

Prevention and treatment of complications are the backbone of medical care, particularly in critical care settings. Early detection and prompt intervention can potentially prevent complications from occurring and improve outcomes. In this study, we use four longitudinal vital signs variables of intensive care unit patients, focusing on predicting acute hypertensive episodes (AHEs). These episodes represent elevations in blood pressure and may result in clinical damage or indicate a change in a patient's clinical situation, such as an elevation in intracranial pressure or kidney failure. Prediction of AHEs may allow clinicians to anticipate changes in the patient's condition and respond early on to prevent these from occurring. Temporal abstraction was employed to transform the multivariate temporal data into a uniform representation of symbolic time intervals, from which frequent time-intervals-related patterns (TIRPs) are mined and used as features for AHE prediction. A novel TIRP metric for classification, called coverage, is introduced that measures the coverage of a TIRP's instances in a time window. For comparison, several baseline models were applied on the raw time series data, including logistic regression and sequential deep learning models, are used. Our results show that using frequent TIRPs as features outperforms the baseline models, and the use of the coverage, metric outperforms other TIRP metrics. Two approaches to predicting AHEs in real-life application conditions are evaluated: using a sliding window to continuously predict whether a patient would experience an AHE within a specific prediction time period ahead, our models produced an AUC-ROC of 82%, but with low AUPRC. Alternatively, predicting whether an AHE would generally occur during the entire admission resulted in an AUC-ROC of 74%.

Hypertensive Emergencies: Common Presentations and Pharmacological Interventions

Depending on end-organ involvement, hypertensive crisis is classified as hypertensive urgency or hypertensive emergency. The recognition of a hypertensive crisis will lead to the adequate reduction of blood pressure to ameliorate the incidence of end-organ damage. Hypertensive crises result from dysfunction in the renin-angiotensin-aldosterone system and damage to the vascular bed. They occur commonly in the emergency department setting and can lead to increased mortality rates if not treated. Registered nurses play a vital role in assessing patients and administering medications during hypertensive crises. This article will outline the assessment strategies that registered nurses should implement in critical care units while patients are receiving antihypertensive drugs. We will also underscore the significance of monitoring specific laboratory values to mitigate the potential side effects of these drugs and exclude them when contraindicated.

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.

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.

Hypertension Urgencies and Emergencies: The GEAR Project

Acute elevations in blood pressure (BP), usually defined as ≥ 180/110 mmHg, may present with highly heterogeneous profiles ranging from absence of symptoms to life-threatening target organ damage. In most recent years the diagnostic approach and the treatment of hypertension have gained interest by patients and physicians. The GEAR project (Gestione delle Emergenze e urgenze in ARea critica, management of hypertensive emergencies and hypertensive urgencies in the emergency setting) was proposed by the group of Young Investigators of the Italian Society of Hypertension as a survey aimed to evaluate the awareness, diagnosis and treatment of hypertensive emergencies and urgencies in Italy.

Hypertensive crisis: clinical characteristics of patients with hypertensive urgency, emergency and pseudocrisis at a public emergency department

Objective:

To assess patients with hypertensive crisis, classified as urgency, emergency or pseudocrisis, and identify the associated variables.

Methods:

We evaluated a total of 508 patients (57% women; 56.3±13.8 years old) with hypertensive crisis (diastolic blood pressure of 120mmHg), aged 18 years or over, seen at the emergency department of a public general hospital.

Results:

The prevalence of hypertensive crises was 6/1,000; in that, 71.7% presented hypertensive urgency, 19.1% hypertensive emergency, and 9.2% hypertensive pseudocrisis. In the multinominal logistic regression, pseudocrisis and urgency conditions were compared to hypertensive emergency. Therefore, the presence of pain (OR: 55.58; 95%CI: 10.55-292.74) except chest pain and headache, and emotional problems (OR: 17.13; 95%CI: 2.80-104.87) increased the likelihood of hypertensive pseudocrisis. Age >60 years (OR: 0,32; 95%CI: 0.10-0.96) and neurologic problems (OR: 1.5.10^-8; 95%CI: 1.5.10^-8-1.5.10^-8) protected against hypertensive pseudocrisis. The comparison of hypertensive urgency with hypertensive emergency showed that age >60 years (OR: 0.50; 95%CI: 0.27-0.92), neurologic (OR: 0.09; 95%CI: 0.04-0.18) and emotional problems (OR: 0.06; 95%CI: 4.7.10^-3-0.79) protected against hypertensive urgency. Moreover, only headache (OR: 14.28; 95%CI: 3.32-61.47) increased the likelihood of hypertensive urgency.

Conclusion:

Advanced age and neurological problems were associated to hypertensive emergency. Headache was associated with hypertensive urgency. Pain and emotional problems were associated with hypertensive pseudocrisis. Our results can contribute to identifying patients with hypertensive crisis who seek emergency services.

Risk assessment of energy drinks with focus on cardiovascular parameters and energy drink consumption in Europe

To assess the possible cardiovascular risks associated with energy drink (ED) consumption in Europe, a comprehensive literature research was performed in regard to (i) possible ED-induced dose-dependent cardiovascular outcomes, (ii) ED consumption patterns in Europe and (iii) the risks of EDs in combination with alcohol. The identified intervention studies primarily investigated acute ED effects in young healthy adults. Moderate consumption of EDs corresponding to an acute caffeine intake of up to 200 mg did not result in clinically relevant cardiovascular changes in young healthy adults. However, high intake of EDs (about 1 L) was associated with moderate to severe adverse effects in some participants (i.a. prolonged QTc interval, palpitations). Studies have indicated that on some occasions, a substantial proportion of ED consuming children and adolescents (12% in 16 EU Member States) drink EDs in high quantities (≥1 L). This could pose a possible health risk to this group since adverse effects by such high ED consumption have been observed already in young healthy adults. Among further measures that might be considered to minimize this identified risk, policy makers could develop information and educational programs with the aim of raising public awareness.
