RESUMO

BACKGROUND: We studied whether significant differences in care gaps exist between specialists and primary care physicians (PCPs). METHODS: GOAL Canada enrolled patients with CVD or familial hypercholesterolemia (FH) and LDL-C > 2.0 mmol/L despite maximally tolerated statin therapy. During follow-up, physicians received online reminders of treatment recommendations based on Canadian Guidelines. RESULTS: A total of 177 physicians (58% PCPs) enrolled 2009 patients; approximately half of the patients were enrolled by each physician group. Patients enrolled by specialists were slightly older (mean age 63 years vs 62), female (45% vs 40%), Caucasian (77% vs 65%), and had a slightly higher systolic pressure and lower heart rate. Patients enrolled by specialists had less frequent history of FH, diabetes, hypertension, chronic kidney disease and liver disease but more frequent history of coronary artery disease, atrial fibrillation and premature family history of CVD. There was no significant baseline difference in LDL-C, HDL-C or non-HDL-C, although total cholesterol and triglycerides were slightly higher in patients managed by PCPs. At baseline, PCPs were more likely to use statins (80% vs 73%, P = .0002) and other therapies such as niacin or fibrate (10% vs 6%, P = .0006) but similar use of ezetimibe (24% vs 27%, P = .15). At the end of follow-up, specialists used less statins (70% vs 77%, P = .0005) and other therapies (6% vs 10%, P = .007) but more ezetimibe (45% vs 38%, P = .01) and the same frequency of PCSK9i (28% vs 27%, P = .65). The proportion of patients achieving the recommended LDL-C level of 2.0 mmol/L or below (primary endpoint) was similar at last available visit between specialists and PCPs (44% vs 42%, P = .32). CONCLUSION: Despite minor differences in the clinical profile of their patients, both PCPs and specialists actively participate in the management of lipid-lowering therapy in high-risk CVD patients and experience similar challenges and care gaps.

RESUMO

BACKGROUND: Patients with coronary artery disease experience various barriers which impact their ability to optimally manage their condition. Financial barriers may result in cost related non-adherence to medical therapies and recommendations, impacting patient health outcomes. Patient experiences regarding financial barriers remain poorly understood. Therefore, we used qualitative methods to explore the experience of financial barriers to care among patients with heart disease. METHODS: We conducted a qualitative descriptive study of participants in Alberta, Canada with heart disease (n = 13) who perceived financial barriers to care. We collected data using semi-structured face-to-face or telephone interviews inquiring about patients experience of financial barriers and the strategies used to cope with such barriers. Multiple analysts performed inductive thematic analysis and findings were bolstered by member checking. RESULTS: The aspects of care to which participants perceived financial barriers included access to: medications, cardiac rehabilitation and exercise, psychological support, transportation and parking. Some participants demonstrated the ability to successfully self-advocate in order to effectively navigate within the healthcare and social service systems. CONCLUSION: Financial barriers impacted patients' ability to self-manage their cardiovascular disease. Financial barriers contributed to non-adherence to essential medical therapies and health recommendations, which may lead to adverse patient outcomes. Given that it is such a key skill, enhancing patients' self-advocacy and navigation skills may assist in improving patient health outcomes.

RESUMO

Insomnia symptoms (i.e., difficulty falling asleep, difficulty staying asleep, and early morning awakenings) are common among people with cardiovascular disease, and have been linked to adverse cardiovascular health outcomes. Reduced parasympathetic tone is one pathway through which risk may be conferred. The purpose of this study was to evaluate whether insomnia symptoms are associated with lower parasympathetic tone in cardiac rehabilitation patients with suspected insomnia. Participants (N = 121) completed a self-report measure of insomnia severity. 1-min heart rate recovery (HRR), an index of parasympathetic tone, was obtained during a maximal exercise test. Difficulty falling asleep, but not difficulty staying asleep or early awakenings, was associated with attenuated 1-min HRR. When analyses were restricted to participants with moderate and severe insomnia severity (n = 51), the strength of this association increased. In a sample of cardiac rehabilitation patients with insomnia, only the symptom of difficulty falling asleep was associated with lower parasympathetic tone, suggesting that individual insomnia symptoms may show specificity in their associations with physiological mechanisms.

RESUMO

AIMS: Cardiac rehabilitation (CR) reduces the risks of mortality and hospitalisation in patients with coronary artery disease and without diabetes. It is unknown whether patients with diabetes obtain the same benefits from CR. METHODS: We retrospectively examined patients referred to a 12 week CR programme between 1996 and 2010. Associations between CR completion vs non-completion and death, hospitalisation rate and cardiac hospitalisation rate were assessed by survival analysis. RESULTS: Over the study period, 13,158 participants were referred to CR (mean ± SD, age 59.9 ± 11.1 years, 28.9% female, 2,956 [22.5%] with diabetes). Patients with diabetes were less likely to complete CR than those without diabetes (41% vs 56%, p < .0001). Over a median follow-up of 6.6 years, there were 379 deaths in patients with diabetes vs 941 deaths among those without diabetes (12.8% vs 8.9%). Of the non-completers, patients with diabetes had a higher mortality rate compared with those without diabetes (17.7% vs 11.3%). In patients who completed CR, mortality was lower: 11.1% in patients with diabetes vs 7.0% in those without diabetes. In patients with diabetes, CR completion was associated with reduced mortality (HR 0.46 [95% CI 0.37, 0.56]), reduced hospitalisation (HR 0.86 [95% CI 0.76, 0.96]) and reduced cardiac hospitalisation (HR 0.67 [95% CI 0.54, 0.84]). The protective associations were similar to those of patients without diabetes. In multivariable adjusted analyses, all of these associations remained significant. CONCLUSIONS: Patients with diabetes were less likely to complete CR than those without diabetes. However, patients with diabetes who completed CR derived similar apparent reductions in mortality and hospitalisation to patients without diabetes.

RESUMO

AIMS: To discuss issues in the theorization and study of gender observed during a qualitative meta-synthesis of influences on uptake of secondary prevention and cardiac rehabilitation services. BACKGROUND: Women and men can equally benefit from secondary prevention/cardiac rehabilitation and there is a need to understand gender barriers to uptake. DESIGN: Meta-method analysis secondary to meta-synthesis. For the meta-synthesis, a systematic search was performed to identify and retrieve studies published as full papers during or after 1995 and contained: a qualitative research component wholly or in a mixed method design, extractable population specific data or themes for referral to secondary prevention programmes and adults ≥18 years. DATA SOURCES: Databases searched between January 1995-31 October 2011 included: CSA Sociological Abstracts, EBSCOhost CINAHL, EBSCOhost Gender Studies, EBSCOhost Health Source Nursing: Academic Edition, EBSCOhost SPORTDiscus, EBSCOhost SocINDEX. REVIEW METHODS: Studies were reviewed against inclusion/exclusion criteria. Included studies were subject to quality appraisal and standardized data extraction. RESULTS: Of 2264 screened articles, 69 were included in the meta-method analysis. Only four studies defined gender or used gender theories. Findings were mostly presented as inherently the characteristic of gendered worldviews of participants. The major themes suggest a mismatch between secondary prevention/cardiac rehabilitation services and consumers' needs, which are usually portrayed as differing according to gender but may also be subject to intersecting influences such as age or socioeconomic status. CONCLUSION: There is a persistent lack of theoretically informed gender analysis in qualitative literature in this field. Theory-driven gender analysis will improve the conceptual clarity of the evidence base for gender-sensitive cardiac rehabilitation programme development.

RESUMO

Contemporary pharmacologic therapies have greatly improved outcomes in patients with heart failure (HF). Exercise therapy also has become increasingly recognized and utilized over the last decade. Patients with HF undergo significant central and peripheral deconditioning. Aerobic and resistance training in this patient population may improve quality of life, muscular strength, aerobic capacity, and potentially longevity. Those HF patients who are able to remain adherent to exercise training programs may improve their self-monitoring skills with respect to progressive volume overload, as well as their capacity for independent living, thereby reducing the likelihood of rehospitalization.

RESUMO

BACKGROUND: Cardiac rehabilitation (CR) is an efficacious yet underused treatment for patients with coronary artery disease. The objective of this study was to determine the association between CR completion and mortality and resource use. METHODS AND RESULTS: We conducted a prospective cohort study of 5886 subjects (20.8% female; mean age, 60.6 years) who had undergone angiography and were referred for CR in Calgary, AB, Canada, between 1996 and 2009. Outcomes of interest included freedom from emergency room visits, hospitalization, and survival in CR completers versus noncompleters, adjusted for clinical covariates, treatment strategy, and coronary anatomy. Hazard ratios for events for CR completers versus noncompleters were also constructed. A propensity model was used to match completers to noncompleters on baseline characteristics, and each outcome was compared between propensity-matched groups. Of the subjects referred for CR, 2900 (49.3%) completed the program, and an additional 554 subjects started but did not complete CR. CR completion was associated with a lower risk of death, with an adjusted hazard ratio of 0.59 (95% confidence interval, 0.49-0.70). CR completion was also associated with a decreased risk of all-cause hospitalization (adjusted hazard ratio, 0.77; 95% confidence interval, 0.71-0.84) and cardiac hospitalization (adjusted hazard ratio, 0.68; 95% confidence interval, 0.55-0.83) but not with emergency room visits. Propensity-matched analysis demonstrated a persistent association between CR completion and reduced mortality. CONCLUSIONS: Among those coronary artery disease patients referred, CR completion is associated with improved survival and decreased hospitalization. There is a need to explore reasons for nonattendance and to test interventions to improve attendance after referral.

RESUMO

BACKGROUND: Greater participation in cardiac rehabilitation improves morbidity and mortality in people with coronary heart disease, but little is understood of patients' decisions to participate. METHODS: To develop interventions aimed at increasing completion of programmes, we conducted a qualitative systematic review and meta-synthesis to explore the complex factors and processes influencing participation in cardiac rehabilitation programmes after referral and initial access. To be included in the review, studies had to contain a qualitative research component, population specific data on programme participation in adults >18 years, and be published ≥1995 as full articles or theses. Ten databases were searched (31 October 2011) using 100+ search terms. RESULTS: Of 2264 citations identified, 62 studies were included involving: 1646 patients (57% female; mean age 64.2), 143 caregivers, and 79 professionals. Patients' participation was most strongly influenced by perceptions of the nature, suitability and scheduling of programmes, social comparisons made possible by programmes, and the degree to which programmes, providers, and programme users met expectations. Women's experiences of these factors rendered them less likely to complete. Comparatively, perceptions of programme benefits had little influence on participation. CONCLUSIONS: Factors reducing participation in programmes are varied but amenable to intervention. Participation should be viewed as a 'consumer behaviour' and interventions should mobilize family support, promote 'patient friendly' scheduling, and actively harness the social, identity-related, and experiential aspects of participation.

RESUMO

BACKGROUND: Cardiac rehabilitation and secondary prevention programs can prevent heart disease in high-risk populations. However, up to half of all patients referred to these programs do not subsequently participate. Although age, sex, and social factors are common predictors of attendance, to increase attendance rates after referral, the complex range of factors and processes influencing attendance needs to be better understood. METHODS: A systematic review using qualitative meta-synthesis was conducted. Ten databases were systematically searched using 100+ search terms until October 31, 2011. To be included, studies had to contain a qualitative research component and population-specific primary data pertaining to program attendance after referral for adults older than 18 years and be published as full articles in or after 1995. RESULTS: Ninety studies were included (2010 patients, 120 caregivers, 312 professionals). Personal and contextual barriers and facilitators were intricately linked and consistently influenced patients' decisions to attend. The main personal factors affecting attendance after referral included patients' knowledge of services, patient identity, perceptions of heart disease, and financial or occupational constraints. These were consistently derived from social as opposed to clinical sources. Contextual factors also influenced patient attendance, including family and, less commonly, health professionals. Regardless of the perceived severity of heart disease, patients could view risk as inherently uncontrollable and any attempts to manage risk as futile. CONCLUSIONS: Decisions to attend programs are influenced more by social factors than by health professional advice or clinical information. Interventions to increase patient attendance should involve patients and their families and harness social mechanisms.

RESUMO

This guideline synthesizes clinical trial data supporting the role of glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter 2 inhibitors (SGLT2i) for treatment of heart failure (HF), chronic kidney disease, and for optimizing prevention of cardiorenal morbidity and mortality in patients with type 2 diabetes. It is on the basis of a companion systematic review and meta-analysis guided by a focused set of population, intervention, control, and outcomes (PICO) questions that address priority cardiorenal end points. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system and a modified Delphi process were used. We encourage comprehensive assessment of cardiovascular (CV) patients with routine measurement of estimated glomerular filtration rate, urinary albumin-creatinine ratio, glycosylated hemoglobin (A1c), and documentation of left ventricular ejection fraction (LVEF) when evaluating symptoms of HF. For patients with HF, we recommend integration of SGLT2i with other guideline-directed pharmacotherapy for the reduction of hospitalization for HF when LVEF is > 40% and for the reduction of all-cause and CV mortality, hospitalization for HF, and renal protection when LVEF is ≤ 40%. In patients with albuminuric chronic kidney disease, we recommend integration of SGLT2i with other guideline-directed pharmacotherapy to reduce all-cause and CV mortality, nonfatal myocardial infarction, and hospitalization for HF. We provide recommendations and algorithms for the selection of glucagon-like peptide-1 receptor agonists and SGLT2i for patients with type 2 diabetes and either established atherosclerotic CV disease or risk factors for atherosclerotic CV disease to reduce all-cause and CV mortality, nonfatal stroke, and for the prevention of hospitalization for HF and decline in renal function. We offer practical advice for safe use of these diabetes-associated agents with profound cardiorenal benefits.

RESUMO

Background We studied care gap in patients with familial hypercholesterolemia (FH) with respect to lipid-lowering therapy. Methods and Results We enrolled patients with cardiovascular disease (CVD) or FH and low-density lipoprotein-cholesterol >2.0 mmol/L despite maximally tolerated statin therapy. During follow-up physicians received online reminders of treatment recommendations of 2009 patients (median age, 63 years, 42% women), 52.4% had CVD only, 31.7% FH only, and 15.9% both CVD and FH. Patients with FH were younger and more likely to be women and non-White with significantly higher baseline low-density lipoprotein-cholesterol level (mmol/L) as compared with patients with CVD (FH 3.92±1.48 versus CVD 2.96±0.94, P<0.0001). Patients with FH received less statin (70.6% versus 79.2%, P=0.0001) at baseline but not ezetimibe (28.1% versus 20.4%, P=0.0003). Among patients with FH only, 45.3% were at low-density lipoprotein target (≥ 50% reduction from pre-treatment level or low-density lipoprotein <2.5 mmol/L) at baseline and increasing to 65.8% and 73.6% by visit 2 and 3, respectively. Among patients with CVD only, none were at recommended level (≤2.0 mmol/L) at baseline and 44.3% and 53.3% were at recommended level on second and third visit, respectively. When primary end point was analyzed as a difference between baseline and last available follow-up observation, only 22.0% of patients with FH only achieved it as compared with 45.8% with CVD only (P<0.0001) and 55.2% with both FH+CVD (P<0.0001). Conclusions There is significant treatment inertia in patients with FH including those with CVD. Education focused on patients with FH should continue to be undertaken.

RESUMO

BACKGROUND: Despite the widespread use of statins, approximately 40% to 50% of Canadian patients with known cardiovascular disease do not achieve the low-density lipoprotein cholesterol (LDL-C) goal. Guidelines Oriented Approach to Lipid lowering (GOAL) is an investigator-initiated study aiming to ascertain the use of second- and third-line therapy and its impact on LDL-C goal achievement in a real-world setting. METHODS: GOAL enrolled patients with clinical vascular disease or familial hypercholesterolemia and LDL-C > 2.0 mmol/L despite maximally tolerated statin therapy. During follow-up, physicians managed patients as clinically indicated but with online reminders of guideline recommendations. RESULTS: Of 2009 patients enrolled (median age 63 years, 42% were female), baseline total cholesterol was 5.5 ± 1.4 mmol/L, LDL-C was 3.3 ± 1.3 mmol/L, non-high-density lipoprotein cholesterol was 4.1 ± 1.4 mmol/L, high-density lipoprotein cholesterol was 1.3 ± 0.4 mmol/L, and triglycerides were 2.0 ± 1.5 mmol/L. Lipid-lowering therapy used at baseline was statin therapy in 76% (with 24% statin intolerant) and ezetimibe in 25%. During follow-up, the proportion of patients achieving an LDL-C level of < 2.0 mmol/L increased significantly to 50.8% as a result of additional lipid-lowering therapy. Patients achieving the recommended LDL-C level were more likely to not be statin intolerant (83.8% vs 70.7%, P < 0.0001) and to be taking a high-efficacy type and dose of statin (52.4% vs 35.9%, P < 0.0001). The 3 top reasons for not using the recommended therapy with ezetimibe were patient refusal in 33%, not needed in 22%, and intolerance in 20%, whereas for PCSK9i the reasons were cost in 26%, not needed in 27%, or patient refusal in 25%. CONCLUSION: The results indicate the feasibility of optimizing management, resulting in achievement of the guideline-recommended LDL-C level. This has the potential to translate into reductions in cardiovascular morbidity and mortality of Canadian patients.


CONTEXTE: Malgré l'utilisation répandue des statines, environ 40 à 50 % des patients canadiens atteints d'une maladie cardiovasculaire connue n'atteignent pas les taux cibles de cholestérol à lipoprotéines de basse densité (C-LDL). L'étude GOAL ( G uidelines O riented A pproach to L ipid lowering) est une étude entreprise par un chercheur afin d'évaluer, en contexte réel, l'utilisation de traitements de deuxième et de troisième intention et les effets de ceux-ci sur l'atteinte des taux cibles de C-LDL. MÉTHODOLOGIE: Des patients atteints d'une maladie vasculaire clinique ou d'une hypercholestérolémie familiale, présentant un taux de C-LDL > 2,0 mmol/l malgré un traitement par une statine à la dose maximale tolérée, ont été inscrits à l'étude GOAL. Pendant la période de suivi, les médecins prenaient en charge le traitement de leurs patients selon les besoins cliniques, mais en recevant par voie électronique des rappels des recommandations formulées dans les lignes directrices. RÉSULTATS: Chez les 2009 patients inscrits à l'étude (âge médian : 63 ans; femmes : 42 %), les taux initiaux moyens étaient les suivants : cholestérol total initial : 5,5 ± 1,4 mmol/l, C-LDL : 3,3 ± 1,3 mmol/l, C non HDL (autre que le cholestérol à lipoprotéines de haute densité) : 4,1 ± 1,4 mmol/l, C-HDL (des lipoprotéines de haute densité) : 1,3 ± 0,4 mmol/l et triglycérides : 2,0 ± 1,5 mmol/l. Le traitement hypolipidémiant utilisé au début de l'étude était composé d'une statine chez 76 % des participants (24 % des patients ne toléraient pas les statines) et d'ézétimibe chez 25 %. Pendant la période de suivi, la proportion de patients atteignant un taux de C-LDL < 2,0 mmol/l a augmenté de façon significative, jusqu'à atteindre 50,8 %, en raison de l'utilisation d'hypolipidémiants additionnels. Les patients atteignant les taux cibles de C-LDL étaient plus susceptibles de ne pas être intolérants aux statines (83,8 % vs 70,7 %, p < 0,0001) et de prendre un type et une dose de statine hautement efficaces (52,4 % vs 35,9 %, p < 0,0001). Les trois principales raisons évoquées pour expliquer le fait de n'avoir pas eu recours au traitement recommandé par l'ézétimibe étaient le refus du patient (33 %), l'absence de besoin (22 %) et l'intolérance (20 %), alors que dans le cas des inhibiteurs de la PCSK9, les raisons données étaient plutôt le coût élevé (26 %), l'absence de besoin (27 %) et le refus du patient (25 %). CONCLUSION: Les résultats de cette étude montrent la faisabilité de l'optimisation de la prise en charge, qui entraîne l'atteinte des taux de C-LDL recommandés dans les lignes directrices. Ces résultats pourraient se traduire par des réductions de la morbidité et de la mortalité d'origine cardiovasculaire chez les patients canadiens.

RESUMO

BACKGROUND: We aimed to determine and compare predictors of postcardiac rehabilitation (CR) cardiorespiratory fitness (CRF), improvements in a large cohort of subjects with varying baseline CRF levels completing CR for ischemic heart disease and to refine prediction models further by baseline CRF. METHODS: The Alberta Provincial Project for Outcomes Assessment in Coronary Heart disease (APPROACH) and TotalCardiology (TotalCardiology, Inc, Calgary, Alberta, Canada) databases were used retrospectively to obtain information on 10,732 (1955 [18.2%] female; mean age 60.4, standard deviation [SD] 10.5 years) subjects who completed the 12-week comprehensive CR program between 1996 and 2016. Peak metabolic equivalents (METs) were determined at program start and completion and identified patients at baseline with low fitness (L-Fit) (< 5 METs), moderate fitness (M-Fit, 5-8 METs), or high fitness (H-Fit, > 8 METs). Multivariable linear regression models were developed to predict METs at completion of the program. RESULTS: Across all fitness groups, mean baseline METs was the strongest predictor of CRF at completion of CR. Other factors-including sex, age, current smoking status, obesity, and diabetes-were highly predictive of post-CR CRF (all P < 0.05). Compared with H-fit patients, coronary artery bypass graft and chronic obstructive pulmonary disease in L-Fit patients, and cerebrovascular disease in M-Fit patients had an additional negative effect on the overall model variance in post-CR CRF. CONCLUSION: Expected CRF at the end of CR is highly predictable, with several key patient factors being clear determinants of CRF. Although most identified patient factors are not modifiable, our analysis highlights populations that may require extra attention over the course of CR to attain maximal benefit.

RESUMO

OBJECTIVE: To provide updated, evidence-based recommendations for the prevention and management of hypertension in adults. OPTIONS AND OUTCOMES: For lifestyle and pharmacological interventions, evidence was reviewed from randomized controlled trials and systematic reviews of trials. Changes in cardiovascular morbidity and mortality were the primary outcomes of interest. However, for lifestyle interventions, blood pressure lowering was accepted as a primary outcome given the lack of long-term morbidity and mortality data in this field. For treatment of patients with kidney disease, the progression of kidney dysfunction was also accepted as a clinically relevant primary outcome. EVIDENCE: A Cochrane collaboration librarian conducted an independent MEDLINE search from 2005 to August 2006 to update the 2006 Canadian Hypertension Education Program recommendations. In addition, reference lists were scanned and experts were contacted to identify additional published studies. All relevant articles were reviewed and appraised independently by both content and methodological experts using prespecified levels of evidence. RECOMMENDATIONS: Dietary lifestyle modifications for prevention of hypertension, in addition to a well-balanced diet, include a dietary sodium intake of less than 100 mmol/day. In hypertensive patients, the dietary sodium intake should be limited to 65 mmol/day to 100 mmol/day. Other lifestyle modifications for both normotensive and hypertensive patients include: performing 30 min to 60 min of aerobic exercise four to seven days per week; maintaining a healthy body weight (body mass index of 18.5 kg/m2 to 24.9 kg/m2) and waist circumference (less than 102 cm in men and less than 88 cm in women); limiting alcohol consumption to no more than 14 units per week in men or nine units per week in women; following a diet reduced in saturated fat and cholesterol, and one that emphasizes fruits, vegetables and low-fat dairy products, dietary and soluble fibre, whole grains and protein from plant sources; and considering stress management in selected individuals with hypertension. For the pharmacological management of hypertension, treatment thresholds and targets should take into account each individual's global atherosclerotic risk, target organ damage and any comorbid conditions: blood pressure should be lowered to lower than 140/90 mmHg in all patients and lower than 130/80 mmHg in those with diabetes mellitus or chronic kidney disease. Most patients require more than one agent to achieve these blood pressure targets. In adults without compelling indications for other agents, initial therapy should include thiazide diuretics; other agents appropriate for first-line therapy for diastolic and/or systolic hypertension include angiotensin-converting enzyme (ACE) inhibitors (except in black patients), long-acting calcium channel blockers (CCBs), angiotensin receptor blockers (ARBs) or beta-blockers (in those younger than 60 years of age). First-line therapy for isolated systolic hypertension includes long-acting dihydropyridine CCBs or ARBs. Certain comorbid conditions provide compelling indications for first-line use of other agents: in patients with angina, recent myocardial infarction, or heart failure, beta-blockers and ACE inhibitors are recommended as first-line therapy; in patients with cerebrovascular disease, an ACE inhibitor plus diuretic combination is preferred; in patients with nondiabetic chronic kidney disease, ACE inhibitors are recommended; and in patients with diabetes mellitus, ACE inhibitors or ARBs (or, in patients without albuminuria, thiazides or dihydropyridine CCBs) are appropriate first-line therapies. All hypertensive patients with dyslipidemia should be treated using the thresholds, targets and agents outlined in the Canadian Cardiovascular Society position statement (recommendations for the diagnosis and treatment of dyslipidemia and prevention of cardiovascular disease). Selected high-risk patients with hypertension who do not achieve thresholds for statin therapy according to the position paper should nonetheless receive statin therapy. Once blood pressure is controlled, acetylsalicylic acid therapy should be considered. 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 reported here achieved at least 95% consensus. These guidelines will continue to be updated annually.
