Special Issue Information

Dear Colleagues,

Systemic arterial hypertension affects around 30%–45% of adults worldwide and is the most prevalent modifiable risk factor for cardiovascular complications. It also called the ‘silent killer’ because, most of the time, it has no specific symptoms.

Hypertension is defined as ‘primary’ (or ‘essential’) when originates from an interaction of genetic and environmental factors without identification of a specific cause. However, in tertiary centers, the prevalence of ‘secondary’ hypertension is up to 35% of patients, in which high blood pressure derives from an underlying and potentially curable disease.

In the last few decades, enormous progress has been made in the workup and management of hypertension. In fact, the early detection of both forms of high blood pressure, along with the proper and targeted treatment, can significantly reduce the development of hypertension-mediated organ damage and the risk of cardiovascular complications, especially in patients with ‘difficult-to-treat’ or resistant hypertension. This form of hypertension is often associated with secondary causes, such as primary aldosteronism (PA) and obstructive sleep apnea (OSA), and it has been demonstrated that the diagnosis and treatment of these conditions is followed by a ‘resolution’ of resistant hypertension.

In terms of diagnosis, many novel techniques have emerged, especially for detecting the most common forms of secondary hypertension. New screening tools are being developed and validated, such as specific questionnaires for early disease detection (e.g., STOP-Bang questionnaire for OSA), as are new diagnostic instruments, such as for drug-induced sleep apnea. Changes in adrenal-vein sampling have been enlightening for PA.

Novel diagnostic methods have been illustrated for primary hypertension as well. For example, the latest European hypertension guidelines marked the superiority of 24-hour ambulatory blood pressure monitoring for diagnosis of hypertension, compared to office measurements. The discussion is now focused on the role of home blood pressure monitoring and the “unattended” automated office blood pressure measurements.

In this Special Issue, we encourage authors to submit original research papers or review articles presenting novel results on the following topics:

  • Screening and diagnostic methods for ‘primary’ and ‘secondary’ hypertension.
  • Diagnostic instruments for early identification of hypertension-mediated organ damage, including vascular remodeling, heart remodeling, renal impairment, cerebrovascular disease (e.g., measuring arterial stiffness, new markers of hypertension nephropathy).
  • Recent findings in the treatment of hypertension: Are there new potential treatments? What about renal denervation and sympathetic activity modulation?
  • New evidence on the workup (diagnosis and treatment) of resistant hypertension.

There is growing evidence that lymphatic system plays a pivotal role in the pathogenesis of hypertension. Here, for the first time, the metabolome of interstitial fluid is analyzed in patients with arterial hypertension. Due to ethical issues to obtain human interstitial fluid samples, this study included only oncological patients after axillary lymph node dissection (ALND). These patients were matched into hypertensive (n = 29) and normotensive (n = 35) groups with similar oncological status. Simultaneous evaluation of interstitial fluid, plasma, and urine was obtained by combining high-resolution proton nuclear magnetic resonance (1H NMR) spectroscopy with chemometric analysis. Orthogonal partial least squares discriminant analysis (OPLS-DA) provided a clear differentiation between the hypertension and normotensive group, with the discrimination visible in each biofluid. In interstitial fluid nine potential metabolomic biomarkers for hypertension could be identified (creatinine, proline, pyroglutamine, glycine, alanine, 1-methylhistidine, the lysyl group of albumin, threonine, lipids), seven distinct markers in plasma (creatinine, mannose, isobutyrate, glycine, alanine, lactate, acetate, ornithine), and seven respectively in urine (methylmalonate, citrulline, phenylacetylglycine, fumarate, citrate, 1-methylnicotinamide, trans-aconitate). Biomarkers in plasma and urine allowed for the identification of specific biochemical pathways involved in hypertension, as previously suggested. Analysis of the interstitial fluid metabolome provided additional biomarkers compared to plasma or urine. Those biomarkers reflected primarily alterations in the metabolism of lipids and amino acids, and indicated increased levels of oxidative stress/inflammation in patients with hypertension.
