Malignant hypertension (MHT) crisis triggers widespread microvascular damage, particularly in the brain. Despite recent MRI evidence highlighting acute cerebral injuries during MHT crises, follow-up data remain scarce. This study seeks to fill this gap by exploring how brain MRI markers evolve following acute MHT crisis management.

Several high-quality, randomized, sham-controlled trials have provided evidence supporting the efficacy and safety of radiofrequency, ultrasound and alcohol catheter-based renal denervation (RDN) for reducing blood pressure (BP). A French clinical consensus document has therefore been developed to propose guidance for the appropriate use of RDN in the management of hypertension along with a dedicated care pathway and management strategy. The French experts group concluded that RDN can serve as an adjunct therapy for patients with confirmed uncontrolled, resistant essential hypertension despite treatment with≥3 antihypertensive drugs, including a long-acting calcium channel blocker, a renin-angiotensin system blocker and a thiazide/thiazide-like diuretic at maximally tolerated doses.

Article Synopsis
  • - The study focused on understanding how common secondary hypertension (2HTN) is in young adults aged 18 to 40, finding that nearly 30% of patients had 2HTN.
  • - The most common causes of 2HTN were identified as primary aldosteronism, renovascular hypertension, and kidney diseases, with certain factors like being female and having a lower BMI linked to a higher prevalence.
  • - Based on their findings, the researchers recommend that all young adults with hypertension should be screened for secondary causes, as there is a significant risk present regardless of age or blood pressure levels.

Article Synopsis
  • Malignant hypertension (MHT) is a severe increase in blood pressure that causes rapid damage to vital organs like the brain, heart, and kidneys, requiring urgent treatment to reduce BP to prevent further complications.
  • The main cause of MHT is often patients not following their prescribed antihypertensive medication, but certain therapies like antiangiogenic and immunosuppressants can also trigger this condition.
  • Despite improvements in treatment leading to better prognoses, patients with MHT remain at a high risk for serious heart and kidney problems, prompting the need for more research and improved management strategies.

Introduction: A major issue confronting clinicians treating hypertension in pregnancy is the limited number of pharmacological options. Endovascular catheter-based renal denervation (RDN) is a new method to lower blood pressure (BP) in patients with hypertension by reducing the activity of the renal sympathetic nervous system. Drugs that affect this system are safe in pregnant women.

Introduction: Whether and how atherosclerotic ischemic stroke patients should be investigated for asymptomatic coronary artery disease (CAD) is controversial. Our aim was to carry out a prospective observational study to determine the frequency and predictors of functionally significant coronary stenosis in these patients as well as the predictors of major adverse cardiovascular events (MACE) during post-stroke follow-up.

Material And Methods: From January 2014 to June 2018, patients with atherosclerotic ischemic stroke were referred from the stroke unit to our cardiovascular department 3+/- 1 months after the acute event where they benefited from evaluation of cardiovascular risk factors, vascular and myocardial disease.

Article Synopsis
  • Arterial stiffness, an indicator of cardiovascular risk, comprises a BP-dependent elastic behavior and long-term structural changes due to various risk factors, which can be assessed using the QKD method through 24-hour monitoring.
  • This study hypothesizes that QKD measured at 100 mmHg SBP and 60 bpm heart rate is unaffected by 24-hour SBP levels in normotensive and treated hypertensive individuals, but shows a weak correlation in untreated hypertensive patients.
  • Results indicated that QKD100-60 was not significantly related to 24-hour SBP in normal and treated hypertensive groups, while showing a weak but noteworthy relationship in untreated hypertensives, suggesting QKD's potential to improve risk assessment in

Arterial stiffness, most often assessed with carotido-femoral pulse wave velocity predicts cardiovascular events but its use in clinical practice remains limited. The 24 h ambulatory monitoring of Blood pressure and timing of Korotkoff sounds (QKD interval) allows an automatic assessment of arterial stiffness and is an independent predictor of cardiovascular events in hypertensive patients. The long term follow up of our cohort of hypertensive patients gave us the opportunity to test the consequences of increased arterial stiffness on the incidence of all causes deaths and to define the populations who could benefit of this measurement beyond risk scores.

Purpose: Primary Aldosteronism (PA) is increasingly considered as a common disease affecting up to 10% of the hypertensive population. Standard of care comprises laparoscopic total adrenalectomy but innovative treatment such as RadioFrequency Ablation (RFA) constitutes an emerging promising alternative to surgery. The main aim of this study is to analyse the cost of RFA versus surgery on aldosterone-producing adenoma patient from the French National Health Insurance (FNHI) perspective.

Background: Primary aldosteronism is responsible for a major cardiovascular risk that can be avoided by specific treatment. A better characterization of the hypertensive population with primary aldosteronism would not only improve the overall diagnosis but also allows a better selection of patients requiring adrenal vein sampling (AVS).

Methods: Creation of a prospective single-center Bordeaux ABORDAGE study of hypertensive patients with primary aldosteronism who underwent AVS.

Background: Acute and diffuse microvascular damage characterizes malignant hypertension (MHT), the deadliest form of hypertension (HTN). Although its ophthalmological, renal and cardiological repercussions are well known, brain involvement is considered rare with few descriptions, although it is one of the main causes of death. We hypothesized that brain MRI abnormalities are common in MHT, even in patients without objective neurological signs.

Ambulatory blood pressure monitoring (ABPM) is now considered the gold standard to evaluate BP, and predicts related cardiovascular risk. However, no study has reported the association of long-term changes in ABPM with the incidence of cardiovascular events, therefore the objective of this work. We included patients from the Bordeaux cohort of hypertensive patients, who had undergone at least two ABPM; the first was performed before or after antihypertensive treatment was started, and the second was the last recording available before any cardiovascular event.

Objective: Short-term blood pressure variability derived from 24-h ambulatory monitoring is associated with poor cardiovascular prognosis. However, previous analyses of this have clearly been influenced by clinical cofounders, particularly blood pressure (BP) level. Arterial stiffness is a powerful marker of cardiovascular risk, which may influence BP variability.

Objective: To evaluate the efficacy and the feasibility of radiofrequency ablation to treat aldosterone-producing adenomas.

Methods: In an open prospective bicentric pilot study, patients with hypertension on ambulatory blood pressure measurement, a primary aldosteronism, an adenoma measuring less than 4 cm, and confirmation of lateralization by adrenal venous sampling were recruited. The primary endpoint, based on ABPM performed at 6 months after the radiofrequency ablation, was a daytime SBP/DBP less than 135/85 mmHg without any antihypertensive drugs or a reduction of at least 20 mmHg for SBP or 10 mmHg for DBP.
