Midaortic Syndrome

Arterial hypertension is a common finding in patients with neurofibromatosis (NF) type 1. Renovascular hypertension due to renal artery stenosis or midaortic syndrome could be the underlying cause. We report the case of a 4-year-old girl with NF type 1 and midaortic syndrome whose changes in blood pressure and pulse wave velocity suggested the evolution of vasculopathy, diagnosis of renovascular hypertension, and provided insights of response to treatment. Hypertension persisted after percutaneous transluminal angioplasty in the abdominal aorta, requiring escalation of antihypertensive treatment, while arterial stiffness demonstrated a mild decrease. Regular assessment of blood pressure using ambulatory blood pressure monitoring and noninvasive assessment of arterial stiffness may enhance the medical care of patients with NF type 1.

Hypertension In Children

AbstractPaediatric hypertension, defined as systolic blood pressure > 95th percentile for age, sex and height is often incidentally diagnosed. Renovascular hypertension (RVH) is responsible for 5–25% of hypertension in children. Renal artery stenosis and middle aortic syndrome can both can be associated with various conditions such as fibromuscular dysplasia, Williams syndrome & Neurofibromatosis type 1. This paper discusses the approaches to diagnosis and interventional management and outcomes of renovascular hypertension in children. Angiography is considered the gold standard in establishing the diagnosis of renovascular disease in children. Angioplasty is beneficial in the majority of patients and generally repeated angioplasty is considered more appropriate than stenting. Surgical options should first be considered before placing a stent unless there is an emergent requirement. Given the established safety and success of endovascular intervention, at most institutions it remains the preferred treatment option.

Average Variation

The arterial baroreceptor control of the sinus node operating in unanesthetized conditions was evaluated in 10 cats in which blood pressure was recorded intra-arterially and scanned by a computer to identify the "spontaneous" sequences of three or more consecutive beats in which systolic blood pressure (SBP) progressively rose and pulse interval (PI) progressively lengthened (type 1 sequences) or SBP progressively fell and PI progressively shortened (type 2 sequences). Many type 1 and 2 three-beat sequences were found; four-, five-, and six-beat sequences of either type were progressively less common, and sequences longer than six beats were almost never identified. The regression coefficient was 30% greater for type 1 than for type 2 sequences. However a prominent feature of either regression coefficient was a wide scattering in each cat (average variation coefficient 50.9 +/- 5.5%). The regression coefficient values were related to some extent to the PI but not to the SBP existing at the beginning of the sequence. Sinoaortic denervation dramatically reduced the number of sequences of either type. These data validate a method for collecting a large number of observations on the baroreceptor-heart rate reflex in physiological conditions. This method may improve understanding of baroreflex involvement in integrated cardiovascular regulation.

Arterial Stiffness Index

Chronic kidney disease (CKD) affects approximately two million people (in a population of 20 million) in Romania. Hypertension is often associated with CKD and both (hypertension and CKD) are risk factors for cardiovascular (CV) events. Ambulatory blood pressure monitoring (ABPM) is increasingly used all around the world for the diagnosis and monitoring of BP (blood pressure) because it is proven that the ABPM is superior to office BP measurements in evaluating patients with hypertension, with or without CKD. Reduced nocturnal BP fall (non-dipping or reverse-dipping patterns) is associated with target organ damage, especially kidney disease and the proportion of non-dippers and reverse-dippers patients increases progressively with the reduction of glomerular filtration rate (GFR). Another ABPM parameter, ambulatory arterial stiffness index (AASI), is an index which was recently proposed for the evaluation of arterial stiffness (a better tool than PP). It has prognostic value for cardiac death and stroke and several studies have showed that is negatively related to eGFR and is positively related to albuminuria. Hyperbaric area index (HBI) might be considered a novel sensitive marker [independent of patterns of NBPC (nocturnal BP change)] for the reduction of kidney function. These facts suggest that ABPM offers multiple useful data with impact, not only in future CV and renal outcomes assessment, but also in the treatment and management of hypertensive patients with CKD.
