Abstract

Among patients with resistant hyperten-sion, it is very important to select patients most likely to benefit from renal sympa-thetic denervation, because they represent a very mixed group of diagnoses. 

Prior to diagnosing a patient as having resistant hypertension, it is important to document adherence and exclude white-coat hypertension, inaccurate measure-ments of blood pressure and secondary causes of hypertension. 

Renal sympathetic denervation has been demonstrated as an antihypertensive treat-ment in resistant hypertension patients with additional positive effects on glucose metabolism and insulin sensitivity in type 2 diabetes. 

We report a single centre report of renal sympathetic denervation effects in a small cohort of patients with resistant hyperten-sion and stage 2-3 chronic kidney disease. Blood pressure reduction after renal sym-pathetic denervation was sustained at con-secutive follow-up visits one, three and six months when compared to the baseline: office systolic blood pressure was signifi-cantly lower (144 ± 13, 140 ± 17, 141 ± 15 mmHg, p<0.001). 

Randomized clinical trials are required to assess the impact of the reported changes. 

Key words

resistant hypertension, stepwise screening protocol, renal denervation

Science Citation Index Expanded (SciSearch) The Science Citation Index (SCI) is a citation index originally produced by the Institute for Scientific Information (ISI) and created by Eugene Garfield. It (Science Citation Index Expanded) covers more than 8,500 notable and significant journals, across 150 disciplines in science and technology, from 1900 to the present.

Journal Citation Reports/Science Edition Journal Citation Reports/Science Edition aims to evaluate a journal’s value from multiple perspectives including the journal impact factor, descriptive data about a journal’s open access content as well as contributing authors, and provide readers a transparent and publisher-neutral data & statistics information about the journal.

Chemical Abstracts Service Source Index The CAS Source Index (CASSI) Search Tool is an online resource that can quickly identify or confirm journal titles and abbreviations for publications indexed by CAS since 1907, including serial and non-serial scientific and technical publications.

It covered international scientific journals which divided into general information, contents of individual issues, detailed bibliography (references) sections for every publication, as well as full texts of publications in the form of attached files (optional). For now, there are more than 58,000 scientific journals registered at ICI.
