The Outcomes Research Task Force and the Canadian Hypertension Education Program.

The present report is an update on the contribution of the Canadian Hypertension Education Program's (CHEP) Outcomes Research Task Force to the surveillance and monitoring efforts surrounding hypertension and hypertension-related conditions in Canada. Components of the program include advocating national physical measures surveys of blood pressure; analysis of national cross-sectional and longitudinal population-based health surveys that assess hypertension diagnosis and treatment; assessment of national and regional pharmacotherapy patterns using existing commercial databases; assessment of national and regional trends in hypertensive complications (stroke, myocardial infarction and congestive heart failure); development of a national system based on provincial administrative data to assess the incidence, prevalence and management of diagnosed hypertension; and assessing some aspects of CHEP implementation. Preliminary data support a large increase in the diagnosis and treatment of hypertension corresponding to the initiation of CHEP.

The 2004 Canadian recommendations for the management of hypertension: Part III--Lifestyle modifications to prevent and control hypertension.

OBJECTIVE: To provide updated, evidence-based recommendations regarding the role of lifestyle modification in the treatment and prevention of hypertension. OUTCOMES: Lifestyle modification interventions including exercise, weight reduction, alcohol consumption, dietary modification, intake of dietary cations and stress management are reviewed. Antioxidants and fish oil supplements are also reviewed, although specific recommendations cannot be made at present. EVIDENCE: MEDLINE searches were conducted from January 2002 to September 2003 to update the 2001 recommendations for the management of hypertension. Supplemental searches in the Cochrane Collaboration databases were also performed. Reference lists were scanned, experts were contacted, and the personal files of the subgroup members and authors were used to identify additional published studies. All relevant articles were reviewed and appraised independently using prespecified levels of evidence by content and methodology experts. RECOMMENDATIONS: Key recommendations include the following: lifestyle modification should be extended to nonhypertensive individuals who are at risk for developing high blood pressure; 30 min to 45 min of aerobic exercise should be performed on most days (four to five days) of the week; an ideal body weight (body mass index 18.5 kg/m2 to 24.9 kg/m2) should be maintained and weight loss strategies should use a multidisciplinary approach; alcohol consumption should be limited to two drinks or fewer per day, and weekly intake should not exceed 14 standard drinks for men and nine standard drinks for women; a reduced fat, low cholesterol diet that emphasizes fruits, vegetables and low fat dairy products, and maintains an adequate intake of potassium, magnesium and calcium, should be followed; salt intake should be restricted to 65 mmol/day to 100 mmol/day in hypertensive individuals and less than 100 mmol/day in normotensive individuals at high risk for developing hypertension; and stress management should be considered as an intervention in selected individuals. VALIDATION: All recommendations were graded according to the strength of the evidence and voted on by the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. Individuals with irreconcilable competing interests (declared by all members, compiled and circulated before the meeting) relative to any specific recommendation were excluded from voting on that recommendation. Only those recommendations achieving at least 70% consensus are reported here. These guidelines will continue to be updated annually.

Anaesthetic management of a parturient with pulmonary stenosis and aortic incompetence for Caesarean section.

Anaesthetic management of Caesarean section in a parturient with severe pulmonary stenosis and aortic regurgitation is described. The valvular sequelae resulted from previous unsuccessful surgical correction (Ross procedure) of congenital aortic stenosis. This case demonstrates the importance of multi-disciplinary assessment and careful anaesthetic planning, to avoid deterioration in perioperative cardiac performance in parturients with complex valvular disease.

Lead pollution and amelioration measures in the community of Frazers Content, St Catherine, Jamaica.

Lead poisoning, especially in children, is a preventable disease. Many children are exposed to this hazard, especially in poor communities, because of a paucity of information on lead poisoning and increasing economic hardships. In 1994, the case of the poor suburban community of Frazers Content, St Catherine, Jamaica, came to the public attention because of the high frequency of hospital admissions, or outpatient treatment, of children for lead poisoning. This paper reviews a Blue Cross of Jamaica-led-initiative aimed at the clean up and education of the Frazers Content community. The following four-pronged approach was employed: environmental and biological sampling and sample analysis, health education, decontamination and community clean up and entrepreneurial activities. The project outputs included: training of 17 community wardens and 22 schoolteachers; the clean up of 64 residences which had lead levels in excess of 500 ppm; the establishment of an entombment site for the contaminated soil in accordance with the Jamaica Natural Resources Conservation Authority and training of residents in entrepreneurial skills, chicken and rabbit rearing and nursery establishment. The paper includes discussion of the lessons learnt and recommendations for future action.

The 2000 Canadian recommendations for the management of hypertension: Part one--therapy.

OBJECTIVE: To provide updated, evidence-based recommendations for the therapy of hypertension in adults. OPTIONS: For patients with hypertension, there are a number of lifestyle manoeuvres and antihypertensive agents that may control blood pressure. Randomized trials evaluating first- line therapy with thiazides, beta-adrenergic antagonists, angiotensin-converting enzyme inhibitors, calcium channel blockers, alpha-blockers, centrally acting agents or angiotensin II receptor antagonists were reviewed. OUTCOMES: The health outcomes considered were changes in blood pressure, cardiovascular morbidity, and cardiovascular and/or all-cause mortality rates. Economic outcomes were not considered due to insufficient evidence. EVIDENCE: Medline searches were conducted from the period of the last revision of the Canadian Recommendations for the Management of Hypertension (May 1998 to October 2000). Reference lists were scanned, experts were polled, and the personal files of the subgroup members and authors were used to identify other studies. All relevant articles were reviewed and appraised, using prespecified levels of evidence, by content experts and methodological experts. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and mortality. BENEFITS, HARMS, AND COSTS: Various lifestyle manoeuvres and antihypertensive agents reduce the blood pressure of patients with sustained hypertension. In certain settings, and for specific classes of drugs, blood pressure lowering has been associated with reduced cardiovascular morbidity and/or mortality. RECOMMENDATIONS: The present document contains detailed recommendations pertaining to all aspects of the therapy of patients with hypertension, including lifestyle modifications proven to lower blood pressure, treatment thresholds, target blood pressures, choice of agents in various settings and strategies to enhance adherence. Lower thresholds for blood pressure treatment are advocated for people with other cardiovascular risk factors or established hypertensive target organ damage. Implicit in the recommendations for therapy is the principle that treatment should be individualized for each patient and the choice of agent should be dictated by coexistent conditions. For the treatment of uncomplicated essential hypertension, thiazides, beta-adrenergic antagonists, angiotensin-converting enzyme inhibitors or calcium channel blockers may be appropriate, depending on individual circumstances. VALIDATION: All recommendations were graded according to strength of the evidence and voted on by the Canadian Hypertension Recommendations Working Group. Only those recommendations achieving high levels of consensus are reported here. These guidelines will be updated annually.
