Abstract: OBJECTIVE: To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with hypertension. OPTIONS AND OUTCOMES: The diagnosis of hypertension is dependent on appropriate blood pressure measurement, the timely assessment of serially elevated readings, the degree of blood pressure elevation, the method of measurement (office, ambulatory, home) and associated comorbidities. The presence of cardiovascular risk factors and target organ damage should be ascertained to assess global cardiovascular risk and determine the urgency, intensity and type of treatment required. EVIDENCE: MEDLINE searches were conducted from November 2007 to October 2008 with the aid of a medical librarian. Reference lists were scanned, experts were contacted, and the personal files of authors and subgroup members were used to identify additional studies. Content and methodological experts assessed studies using prespecified, standardized evidence-based algorithms. Recommendations were based on evidence from peer-reviewed full-text articles only. RECOMMENDATIONS: Recommendations for blood pressure measurement, criteria for hypertension diagnosis and follow-up, assessment of global cardiovascular risk, diagnostic testing, diagnosis of renovascular and endocrine causes of hypertension, home and ambulatory monitoring, and the use of echocardiography in hypertensive individuals are outlined. Key messages include continued emphasis on the expedited, accurate diagnosis of hypertension, the importance of global risk assessment and the need for ongoing monitoring of hypertensive patients to identify incident type 2 diabetes. VALIDATION: All recommendations were graded according to strength of the evidence and voted on by the 57 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations were required to be supported by at least 70% of task force members. These guidelines will continue to be updated annually.

Abstract: OBJECTIVE: To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with hypertension. OPTIONS AND OUTCOMES: The diagnosis of hypertension is dependent on the appropriate measurement of blood pressure, the timely assessment of serially elevated readings, the degree of blood pressure elevation, the method of measurement (office, ambulatory, home) and any associated comorbidities. The presence of cardiovascular risk factors and target organ damage should be ascertained to assess global cardiovascular risk, and to determine the urgency, intensity and type of treatment required. EVIDENCE: MEDLINE searches were conducted from November 2005 to October 2006 with the aid of a medical librarian. Reference lists were scanned, experts were contacted, and the personal files of authors and subgroup members were used to identify additional studies. Content and methodological experts assessed studies using prespecified, standardized evidence-based algorithms. Recommendations were based on evidence from peer-reviewed, full-text articles only. RECOMMENDATIONS: Recommendations for blood pressure measurement, criteria for hypertension diagnosis and follow-up, assessment of global cardiovascular risk, diagnostic testing, diagnosis of renovascular and endocrine causes of hypertension, home and ambulatory monitoring, and the use of echocardiography in hypertensive individuals are outlined. Key messages in 2007 include continued emphasis on the expedited, accurate diagnosis of hypertension, the importance of assessing the risk of cerebrovascular events as part of global risk assessment, the need for ongoing reassessment of patients with high normal blood pressure, and reviews of recent studies involving laboratory testing and home monitoring. VALIDATION: All recommendations were graded according to strength of the evidence and were voted on by the 57 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported here received at least 70% consensus. These guidelines will continue to be updated annually.

Abstract: OBJECTIVE: To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with high blood pressure. OPTIONS AND OUTCOMES: For persons in whom a high blood pressure value is recorded, a diagnosis of hypertension is dependent on the appropriate measurement of blood pressure, the level of the blood pressure elevation, the approach used to monitor blood pressure (office, ambulatory or home/self), and the duration of follow-up. In addition, the presence of cardiovascular risk factors and target organ damage should be assessed to determine the urgency, intensity and type of treatment. For persons diagnosed as having hypertension, estimating the overall risk of adverse cardiovascular outcomes requires an assessment for other vascular risk factors and hypertensive target organ damage. EVIDENCE: MEDLINE searches were conducted from November 2004 to October 2005 to update the 2005 recommendations. Reference lists were scanned, experts were polled, and the personal files of the authors and subgroup members were used to identify other studies. Identified articles were reviewed and appraised using prespecified levels of evidence by content and methodological experts. As per previous years, the authors only included studies that had been published in the peer-reviewed literature and did not include evidence from abstracts, conference presentations or unpublished personal communications. RECOMMENDATIONS: The present document contains recommendations for blood pressure measurement, diagnosis of hypertension, and assessment of cardiovascular risk for adults with high blood pressure. These include the accurate measurement of blood pressure, criteria for the diagnosis of hypertension and recommendations for follow-up, assessment of overall cardiovascular risk, routine and optional laboratory testing, assessment for renovascular and endocrine causes, home and ambulatory blood pressure monitoring, and the role of echocardiography for those with hypertension. Key features of the 2006 recommendations include continued emphasis on an expedited diagnosis of hypertension, an in-depth review of the role of global risk assessment in hypertension therapy, and the use of home/self blood pressure monitoring for patients with masked hypertension (subjects with hypertension who have a blood pressure that is normal in clinic but elevated on home/self measurement). VALIDATION: All recommendations were graded according to the strength of the evidence and were voted on by the 45 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported herein received at least 95% consensus. These guidelines will continue to be updated annually.

Abstract: OBJECTIVE: To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with high blood pressure (BP). OPTIONS AND OUTCOMES: For persons in whom a high BP value is recorded, the assignment of a diagnosis of hypertension is dependent on the appropriate measurement of BP, the level of the BP elevation and the duration of follow-up. In addition, the presence of cardiovascular risk factors and target organ damage should be assessed to determine the urgency, intensity and type of treatment. For persons diagnosed as having hypertension, estimating overall risk of adverse cardiovascular outcomes requires an assessment of other vascular risk factors and hypertensive target organ damage. EVIDENCE: MEDLINE searches were conducted from November 2003 to October 2004 to update the 2004 recommendations. Reference lists were scanned, experts were polled, and the personal files of the authors and subgroup members were used to identify other studies. Identified articles were reviewed and appraised using prespecified levels of evidence by content and methodological experts. As per previous years, only studies that had been published in the peer-reviewed literature were included; evidence from abstracts, conference presentations and unpublished personal communications was not included. RECOMMENDATIONS: This document contains recommendations for BP measurement, diagnosis of hypertension and assessment of cardiovascular risk for adults with high BP. These include the accurate measurement of BP, criteria for diagnosis of hypertension, and recommendations for follow-up, assessment of overall cardiovascular risk, routine and optional laboratory testing, assessment for renovascular and endocrine causes, home and ambulatory BP monitoring, and the role of echocardiography for those with hypertension. Key features of the 2005 recommendations include an expedited diagnostic algorithm for hypertension and an endorsement of the use of home/self and ambulatory BP assessment as validated techniques in establishing the diagnosis of hypertension. VALIDATION: All recommendations were graded according to the strength of the evidence and voted on by the 43 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported in the present paper received at least 95% consensus. These guidelines will continue to be updated annually.

Abstract: PURPOSE: Hydrogen Sulfide has been found to be produced endogenously in amounts that cause vasodilatation. The purpose of this review is to outline the effects of hydrogen sulfide as a gasotransmitter. METHODS: This article is a summary of work done in Dr. Rui Wang's laboratory and a comprehensive review of H2S on the Pub-Med website. PRINCIPLE FINDINGS: One of the specific cellular targets of hydrogen sulfide is the K(ATP) channel protein which produces vasodilatation. The other gasotransmitters like NO (nitric oxide) interact with hydrogen sulfide in complex ways. This action could be important in hypertension and other vascular diseases. CONCLUSION: Gasotransmitter research is relevant to the pathophysiology of a number of cardiovascular disease processes.

Abstract: INTRODUCTION: All students (N = 2053) in Anadarko public schools, grades kindergarten through 12, were invited to be screened for height, weight, and blood pressure to assess the health status of this multiracial, multiethnic (American Indian, white, African American, and Hispanic) population in southwestern Oklahoma. METHODS: The Centers for Disease Control and Prevention's 2000 growth charts were used to determine body mass index (BMI) percentiles, and standards from the National High Blood Pressure Education Program Working Group on Hypertension Control in Children and Adolescents were used to assess blood pressure. RESULTS: Seven hundred sixty-nine students with active consent participated in the screening. Of these, approximately 28% were overweight. American Indians were at significantly greater risk of being overweight or at risk for overweight than whites (relative risk [RR], 1.4; 95% confidence interval [CI], 1.1-1.7) as were African Americans (RR, 1.5; 95% CI, 1.1-2.0), whereas Hispanics (RR, 1.3; 95% CI, 0.9-2.0) did not have a statistically significant increased risk compared with whites. BMI at or above the 95th percentile was strongly associated with elevated blood pressure (> or =90th percentile) (RR, 3.8; 95% CI, 2.6-5.4). CONCLUSION: Students who participated in this BMI screening in the Anadarko public school system evidenced high rates of excess weight, with American Indians and African Americans at greatest risk. Elevated BMI was strongly associated with elevated blood pressure.
