RESUMO

Hypertension Canada's 2020 guidelines for the prevention, diagnosis, risk assessment, and treatment of hypertension in adults and children provide comprehensive, evidence-based guidance for health care professionals and patients. Hypertension Canada develops the guidelines using rigourous methodology, carefully mitigating the risk of bias in our process. All draft recommendations undergo critical review by expert methodologists without conflict to ensure quality. Our guideline panel is diverse, including multiple health professional groups (nurses, pharmacy, academics, and physicians), and worked in concert with experts in primary care and implementation to ensure optimal usability. The 2020 guidelines include new guidance on the management of resistant hypertension and the management of hypertension in women planning pregnancy.

RESUMO

Murine models are widely used valuable tools to study deep vein thrombosis (VT). Leading experts in VT research came together through the American Venous Forum to develop a consensus on maximizing the utility and application of available mouse models of VT. In this work, we provide an algorithm for model selection, with discussion of the advantages, disadvantages, and applications of the main mouse models of VT. Additionally, we provide a detailed surgical description of the models with guidelines to validate surgical technique.

RESUMO

OBJECTIVE: Hypertensive disorders of pregnancy (HDP) comprise an independent, sex-specific risk factor for cardiovascular disease (CVD) in women. This study examined the utility of CVD risk models proposed in the 2016 Canadian Cardiovascular Society (CCS) lipid guidelines to identify women requiring further screening or lipid treatment following HDP. METHODS: Using data collected from the postpartum Maternal Health Clinic (MHC) at Kingston General Hospital in Kingston, Ontario and the Preeclampsia New Emerging Team (PE-NET) cohort study, the study investigators used the models recommended by the CCS guidelines and the cardiometabolic model of life expectancy in each cohort to estimate CVD risk in women after HDP. (Canadian Task Force Classification II-2). RESULTS: Using the 10-Year Modified Framingham Risk Score, all women were classified by the 2016 CCS Guidelines as low risk, requiring no follow-up. The 30-Year and Lifetime Risk Scores resulted in significant reclassification of women at risk in the PE-NET control and HDP groups (P < 0.001 and P < 0.0001, respectively); 49.2% of women with HDP were classified as high risk, requiring follow-up, compared with 14.3% of control subjects. Using the cardiometabolic model, median life expectancy was significantly lower and expected onset of CVD was earlier in the HDP group compared with the control group (P < 0.0001). CONCLUSION: The 2016 CCS lipid guidelines' risk classification recommendations significantly underestimated lifelong CVD risk in the HDP group compared with the control group. Women with HDP also had a significant decrease in cardiometabolic life expectancy and an earlier predicted age at onset of CVD. Early primary prevention in this at-risk population may improve CVD outcomes and reduce the future burden on the health care system.

RESUMO

Hypertension Canada provides annually updated, evidence-based guidelines for the diagnosis, assessment, prevention, and treatment of hypertension in adults and children. This year, the adult and pediatric guidelines are combined in one document. The new 2018 pregnancy-specific hypertension guidelines are published separately. For 2018, 5 new guidelines are introduced, and 1 existing guideline on the blood pressure thresholds and targets in the setting of thrombolysis for acute ischemic stroke is revised. The use of validated wrist devices for the estimation of blood pressure in individuals with large arm circumference is now included. Guidance is provided for the follow-up measurements of blood pressure, with the use of standardized methods and electronic (oscillometric) upper arm devices in individuals with hypertension, and either ambulatory blood pressure monitoring or home blood pressure monitoring in individuals with white coat effect. We specify that all individuals with hypertension should have an assessment of global cardiovascular risk to promote health behaviours that lower blood pressure. Finally, an angiotensin receptor-neprilysin inhibitor combination should be used in place of either an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in individuals with heart failure (with ejection fraction < 40%) who are symptomatic despite appropriate doses of guideline-directed heart failure therapies. The specific evidence and rationale underlying each of these guidelines are discussed.

RESUMO

BACKGROUND: Evolocumab, a proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitor, has been shown to reduce low-density lipoprotein levels by up to 60%. Despite the absence of a reduction in overall or cardiovascular mortality in the Further Cardiovascular Outcomes Research With PCSK9 Inhibition in Subjects With Elevated Risk (FOURIER) trial, some believe that, with longer treatment, such a benefit might eventually be realized. Our aim was to estimate the potential mortality benefit over a patient's lifetime and the cost per year of life saved (YOLS) for an average Canadian with established coronary artery disease. We also sought to estimate the price threshold at which evolocumab might be considered cost-effective for secondary prevention in Canada. METHODS: We calibrated the Cardio-metabolic Model, a well-validated tool for predicting cardiovascular events and life expectancy, to the reduction in nonfatal events seen in the FOURIER trial. Assuming that long-term treatment will eventually result in mortality benefits, we estimated YOLSs and cost per YOLS with evolocumab treatment plus a statin compared to a statin alone. We then estimated the annual drug costs that would provide a 50% chance of being cost-effective at willingness-to-pay values of $50 000 and $100 000. RESULTS: In secondary prevention in patients similar to those in the FOURIER study, evolocumab treatment would save an average of 0.34 (95% confidence interval [CI] 0.27-0.41) life-years at a cost of $101 899 (95% CI $97 325-$106 473), yielding a cost per YOLS of $299 482. We estimate that to have a 50% probability of achieving a cost per YOLS below $50 000 and $100 000 would require annual drug costs below $1200 and $2300, respectively. INTERPRETATION: At current pricing, the use of evolocumab for secondary prevention is unlikely to be cost-effective in Canada.

RESUMO

Hypertension Canada provides annually updated, evidence-based guidelines for the diagnosis, assessment, prevention, and treatment of hypertension. This year, we introduce 10 new guidelines. Three previous guidelines have been revised and 5 have been removed. Previous age and frailty distinctions have been removed as considerations for when to initiate antihypertensive therapy. In the presence of macrovascular target organ damage, or in those with independent cardiovascular risk factors, antihypertensive therapy should be considered for all individuals with elevated average systolic nonautomated office blood pressure (non-AOBP) readings ≥ 140 mm Hg. For individuals with diastolic hypertension (with or without systolic hypertension), fixed-dose single-pill combinations are now recommended as an initial treatment option. Preference is given to pills containing an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in combination with either a calcium channel blocker or diuretic. Whenever a diuretic is selected as monotherapy, longer-acting agents are preferred. In patients with established ischemic heart disease, caution should be exercised in lowering diastolic non-AOBP to ≤ 60 mm Hg, especially in the presence of left ventricular hypertrophy. After a hemorrhagic stroke, in the first 24 hours, systolic non-AOBP lowering to < 140 mm Hg is not recommended. Finally, guidance is now provided for screening, initial diagnosis, assessment, and treatment of renovascular hypertension arising from fibromuscular dysplasia. The specific evidence and rationale underlying each of these guidelines are discussed.

RESUMO

Based on the job demands-resources (JD-R) model, this study examines the different ways that the personal resource of mindfulness reduces stress. Structural equation modeling based on data from 415 Australian nurses shows that mindfulness relates directly and negatively to work stress and perceptions of emotional demands as well as buffering the relation of emotional demands on psychological stress. This study contributes to the literature by employing empirical analysis to the task of unravelling how personal resources function within the JD-R model. It also introduces mindfulness as a personal resource in the JD-R model.

RESUMO

Hypertension Canada's Canadian Hypertension Education Program Guidelines Task Force provides annually updated, evidence-based recommendations to guide the diagnosis, assessment, prevention, and treatment of hypertension. This year, we present 4 new recommendations, as well as revisions to 2 previous recommendations. In the diagnosis and assessment of hypertension, automated office blood pressure, taken without patient-health provider interaction, is now recommended as the preferred method of measuring in-office blood pressure. Also, although a serum lipid panel remains part of the routine laboratory testing for patients with hypertension, fasting and nonfasting collections are now considered acceptable. For individuals with secondary hypertension arising from primary hyperaldosteronism, adrenal vein sampling is recommended for those who are candidates for potential adrenalectomy. With respect to the treatment of hypertension, a new recommendation that has been added is for increasing dietary potassium to reduce blood pressure in those who are not at high risk for hyperkalemia. Furthermore, in selected high-risk patients, intensive blood pressure reduction to a target systolic blood pressure ≤ 120 mm Hg should be considered to decrease the risk of cardiovascular events. Finally, in hypertensive individuals with uncomplicated, stable angina pectoris, either a ß-blocker or calcium channel blocker may be considered for initial therapy. The specific evidence and rationale underlying each of these recommendations are discussed. Hypertension Canada's Canadian Hypertension Education Program Guidelines Task Force will continue to provide annual updates.

RESUMO

Deep vein thrombosis and common complications, including pulmonary embolism and post-thrombotic syndrome, represent a major source of morbidity and mortality worldwide. Experimental models of venous thrombosis have provided considerable insight into the cellular and molecular mechanisms that regulate thrombus formation and subsequent resolution. Here, we critically appraise the ex vivo and in vivo techniques used to assess venous thrombosis in these models. Particular attention is paid to imaging modalities, including magnetic resonance imaging, micro-computed tomography, and high-frequency ultrasound that facilitate longitudinal assessment of thrombus size and composition.

RESUMO

The Canadian Hypertension Education Program reviews the hypertension literature annually and provides detailed recommendations regarding hypertension diagnosis, assessment, prevention, and treatment. This report provides the updated evidence-based recommendations for 2015. This year, 4 new recommendations were added and 2 existing recommendations were modified. A revised algorithm for the diagnosis of hypertension is presented. Two major changes are proposed: (1) measurement using validated electronic (oscillometric) upper arm devices is preferred over auscultation for accurate office blood pressure measurement; (2) if the visit 1 mean blood pressure is increased but < 180/110 mm Hg, out-of-office blood pressure measurements using ambulatory blood pressure monitoring (preferably) or home blood pressure monitoring should be performed before visit 2 to rule out white coat hypertension, for which pharmacologic treatment is not recommended. A standardized ambulatory blood pressure monitoring protocol and an update on automated office blood pressure are also presented. Several other recommendations on accurate measurement of blood pressure and criteria for diagnosis of hypertension have been reorganized. Two other new recommendations refer to smoking cessation: (1) tobacco use status should be updated regularly and advice to quit smoking should be provided; and (2) advice in combination with pharmacotherapy for smoking cessation should be offered to all smokers. The following recommendations were modified: (1) renal artery stenosis should be primarily managed medically; and (2) renal artery angioplasty and stenting could be considered for patients with renal artery stenosis and complicated, uncontrolled hypertension. The rationale for these recommendation changes is discussed.

RESUMO

BACKGROUND: Survivors of ischemic stroke/transient ischemic attack (TIA) are at high risk for other vascular events. We evaluated the impact of 2 types of case management (hard touch with pharmacist or soft touch with nurse) added to usual care on global vascular risk. METHODS: This is a prespecified secondary analysis of a 6-month trial conducted in outpatients with recent stroke/TIA who received usual care and were randomized to additional monthly visits with either nurse case managers (who counseled patients, monitored risk factors, and communicated results to primary care physicians) or pharmacist case managers (who were also able to independently prescribe according to treatment algorithms). The Framingham Risk Score [FRS]) and the Cardiovascular Disease Life Expectancy Model (CDLEM) were used to estimate 10-year risk of any vascular event at baseline, 6 months (trial conclusion), and 12 months (6 months after last trial visit). RESULTS: Mean age of the 275 evaluable patients was 67.6 years. Both study arms were well balanced at baseline and exhibited reductions in absolute global vascular risk estimates at 6 months: median 4.8% (Interquartile range (IQR) 0.3%-11.3%) for the pharmacist arm versus 5.1% (IQR 1.9%-12.5%) for the nurse arm on the FRS (P = .44 between arms) and median 10.0% (0.1%-31.6%) versus 12.5% (2.1%-30.5%) on the CDLEM (P = .37). These reductions persisted at 12 months: median 6.4% (1.2%-11.6%) versus 5.5% (2.0%-12.0%) for the FRS (P = .83) and median 8.4% (0.1%-28.3%) versus 13.1% (1.6%-31.6%) on the CDLEM (P = .20). CONCLUSIONS: Case management by nonphysician providers is associated with improved global vascular risk in patients with recent stroke/TIA. Reductions achieved during the active phase of the trial persisted after trial conclusion.

RESUMO

Herein, updated evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in Canadian adults are detailed. For 2014, 3 existing recommendations were modified and 2 new recommendations were added. The following recommendations were modified: (1) the recommended sodium intake threshold was changed from ≤ 1500 mg (3.75 g of salt) to approximately 2000 mg (5 g of salt) per day; (2) a pharmacotherapy treatment initiation systolic blood pressure threshold of ≥ 160 mm Hg was added in very elderly (age ≥ 80 years) patients who do not have diabetes or target organ damage (systolic blood pressure target in this population remains at < 150 mm Hg); and (3) the target population recommended to receive low-dose acetylsalicylic acid therapy for primary prevention was narrowed from all patients with controlled hypertension to only those ≥ 50 years of age. The 2 new recommendations are: (1) advice to be cautious when lowering systolic blood pressure to target levels in patients with established coronary artery disease if diastolic blood pressure is ≤ 60 mm Hg because of concerns that myocardial ischemia might be exacerbated; and (2) the addition of glycated hemoglobin (A1c) in the diagnostic work-up of patients with newly diagnosed hypertension. The rationale for these recommendation changes is discussed. In addition, emerging data on blood pressure targets in stroke patients are discussed; these data did not lead to recommendation changes at this time. The Canadian Hypertension Education Program recommendations will continue to be updated annually.

RESUMO

This study investigated whether the positive behavioral and anthropometric outcomes of a pedometer-based physical activity 8-week challenge were maintained 6 months after the end of the program. It further investigated the motivational profile of those who maintained their physical activity levels in the months following the end of the program and of those who did not. Hospital employees from a university-affiliated multisite health care center in Canada participated using a questionnaire. Of the 235 participants who completed the 8-week challenge, 157 questionnaires were returned 6 months later. Paired-samples t tests were conducted between the baseline and follow-up scores as well as between the postprogram and follow-up scores to detect significant differences between the measurement points. This study shows that the pedometer-based physical activity helped hospital employees maintain a high level of physical activity as well as maintain a healthy body mass index after 6 months. The results demonstrated that during maintenance the high physical activity group obtained higher scores for identified regulation and intrinsic regulation compared with the other groups. The results of the study revealed that identified and intrinsic regulations are important contributors to maintaining physical activity among hospital employees.

RESUMO

We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2013. This year's update includes 2 new recommendations. First, among nonhypertensive or stage 1 hypertensive individuals, the use of resistance or weight training exercise does not adversely influence blood pressure (BP) (Grade D). Thus, such patients need not avoid this type of exercise for fear of increasing BP. Second, and separately, for very elderly patients with isolated systolic hypertension (age 80 years or older), the target for systolic BP should be < 150 mm Hg (Grade C) rather than < 140 mm Hg as recommended for younger patients. We also discuss 2 additional topics at length (the pharmacological treatment of mild hypertension and the possibility of a diastolic J curve in hypertensive patients with coronary artery disease). In light of several methodological limitations, a recent systematic review of 4 trials in patients with stage 1 uncomplicated hypertension did not lead to changes in management recommendations. In addition, because of a lack of prospective randomized data assessing diastolic BP thresholds in patients with coronary artery disease and hypertension, no recommendation to set a selective diastolic cut point for such patients could be affirmed. However, both of these issues will be examined on an ongoing basis, in particular as new evidence emerges.

RESUMO

We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2012. The new recommendations are: (1) use of home blood pressure monitoring to confirm a diagnosis of white coat syndrome; (2) mineralocorticoid receptor antagonists may be used in selected patients with hypertension and systolic heart failure; (3) a history of atrial fibrillation in patients with hypertension should not be a factor in deciding to prescribe an angiotensin-receptor blocker for the treatment of hypertension; and (4) the blood pressure target for patients with nondiabetic chronic kidney disease has now been changed to < 140/90 mm Hg from < 130/80 mm Hg. We also reviewed the recent evidence on blood pressure targets for patients with hypertension and diabetes and continue to recommend a blood pressure target of less than 130/80 mm Hg.

RESUMO

We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2011. The major guideline changes this year are: (1) a recommendation was made for using comparative risk analogies when communicating a patient's cardiovascular risk; (2) diagnostic testing issues for renal artery stenosis were discussed; (3) recommendations were added for the management of hypertension during the acute phase of stroke; (4) people with hypertension and diabetes are now considered high risk for cardiovascular events if they have elevated urinary albumin excretion, overt kidney disease, cardiovascular disease, or the presence of other cardiovascular risk factors; (5) the combination of an angiotensin-converting enzyme (ACE) inhibitor and a dihydropyridine calcium channel blocker (CCB) is preferred over the combination of an ACE inhibitor and a thiazide diuretic in persons with diabetes and hypertension; and (6) a recommendation was made to coordinate with pharmacists to improve antihypertensive medication adherence. We also discussed the recent analyses that examined the association between angiotensin II receptor blockers (ARBs) and cancer.

RESUMO

Current expert guidelines for the treatment of hypertension or dyslipidemia recommend the use of cardiovascular risk assessment to identify high-risk individuals most likely to benefit from risk factor management. The potential uses of risk assessment include reassuring low-risk individuals, motivating high-risk individuals to modify their lifestyles or adhere to medical therapy, and track an individual's progress as risk factors come under better control. Despite the potential usefulness of cardiovascular risk assessment in clinical practice, the vast majority of patients have never had their cardiovascular risk assessed. This review describes the strengths and weaknesses of the currently available risk engines and suggests an approach, based on the currently available evidence, that can be used to maximize the clinical impact of risk assessment in daily clinical practice.

RESUMO

OBJECTIVE: To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with hypertension. EVIDENCE: MEDLINE searches were conducted from November 2008 to October 2009 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. Changes to the recommendations for 2010 relate to automated office blood pressure measurements. Automated office blood pressure measurements can be used in the assessment of office blood pressure. When used under proper conditions, an automated office systolic blood pressure of 135 mmHg or higher or diastolic blood pressure of 85 mmHg or higher should be considered analogous to a mean awake ambulatory systolic blood pressure of 135 mmHg or higher and diastolic blood pressure of 85 mmHg or higher, respectively. VALIDATION: All recommendations were graded according to strength of the evidence and voted on by the 63 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force.

RESUMO

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.

RESUMO

BACKGROUND AND OBJECTIVES: The direct health care costs associated with treating hypertension and dyslipidemia continue to grow in most western countries, including Canada. Despite the proven effectiveness of hypertension and lipid therapies to prevent cardiovascular disease, the cost-effectiveness of long-term primary prevention, as currently advocated by Canadian treatment guidelines, remains to be determined. METHODS: Therapeutic efficiency, defined as person-years of treatment per year of life saved (YOLS) and the cost-effectiveness of treatment were estimated for groups of Canadian adults, 40 to 74 years of age. The clinical indications for treatment were based on the Canadian national guidelines in 2005. Analyses focused on those without cardiovascular disease or diabetes using risk factor data from the Canadian heart health surveys and drug data from a national study, the MyHealthCheckUp survey. The expected impact of therapy was based on published results: statins would result in a 40% drop in low-density lipoprotein cholesterol and a 6% increase in high-density lipoprotein cholesterol, while hypertension therapy would result in a 6.4% drop in systolic and a 5.6% drop in diastolic blood pressure. RESULTS: The estimated daily cost of statins was $1.98 versus $1.72 for antihypertensives. Overall, 2.33 million patients would be treated with lipid therapy and 2.34 million with antihypertensives. The average cost-effectiveness of lipid therapy would be approximately $16,700 per YOLS while hypertension therapy would be approximately $37,100 per YOLS. Lifelong lipid and hypertension therapy would be associated with 1.1 million and 472,000 life years saved at a national cost of $18.3 billion and $17.5 billion, respectively. However, hypertension treatment for some groups of Canadians appeared relatively expensive (more than $50,000 per YOLS) including men or women younger than 50 years of age. Despite attractive cost-effectiveness ratios, treatment appeared relatively inefficient (person-years of treatment per YOLS more than 100 years) for statin therapy among women younger than 50 years of age, and hypertension treatment for women younger than 60 years of age and men younger than 50 years of age. CONCLUSIONS: Given Canadian guidelines, the treatment of dyslipidemia or hypertension in primary prevention appears economically attractive overall. However, for some groups of individuals, the forecasted future benefits appear to be relatively small given the many years of treatment that are required.
