Prevention and Management of Cardiovascular Disease in Primary Care: A Comment on the PEER Simplified Lipid Guideline.

Background: In Canada, 2 guidelines provide guidance for the management of dyslipidemia. The Patients, Experience, Evidence, Research simplified lipid guidelines, intended for primary care practitioners, and the Canadian Cardiovascular Society guidelines, intended for all practitioners, are based on differing methodologies with distinct priorities and preferences. The disparate approaches may contribute to confusion among family practitioners and their co-managed patients, with the potential for compromised care, differing standards for training in the fundamentals of lipidology, and differing criteria that might be used in practice audits to evaluate quality of care.

Low-Dose Colchicine in Patients With Type 2 Diabetes and Recent Myocardial Infarction in the Colchicine Cardiovascular Outcomes Trial (COLCOT).

Objective: The cardiovascular benefits of low-dose colchicine have been demonstrated in patients with coronary disease. Its effects were evaluated in this prespecified analysis in patients with type 2 diabetes (T2D) from the Colchicine Cardiovascular Outcomes Trial (COLCOT).

Research Design And Methods: COLCOT was a randomized, double-blinded trial of colchicine, 0.

Cost-Effectiveness of Icosapent Ethyl (IPE) for the Reduction of the Risk of Ischemic Cardiovascular Events in Canada.

Background: Despite the use of statins, many patients with cardiovascular disease (CVD) have persistent residual risk. In a large Phase III trial (REDUCE-IT), icosapent ethyl (IPE) was shown to reduce the first occurrence of the primary composite endpoint of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or hospitalization for unstable angina.

Methods: We conducted a cost-utility analysis comparing IPE to placebo in statin-treated patients with elevated triglycerides, from a publicly funded, Canadian healthcare payer perspective, using a time-dependent Markov transition model over a 20-year time horizon.

Antithrombotic therapies in Canadian atrial fibrillation patients with concomitant coronary artery disease: Insights from the CONNECT AF + PCI-II program.

Background: Selecting the appropriate antithrombotic regimen for patients with atrial fibrillation (AF) who have undergone percutaneous coronary intervention (PCI) or have had medically managed acute coronary syndrome (ACS) remains complex. This multi-centre observational study evaluated patterns of antithrombotic therapies utilized among Canadian patients with AF post-PCI or ACS.

Methods And Results: By retrospective chart audit, 611 non-valvular AF patients [median (interquartile range) age 76 (69-83) years, CHADS score 2 (1-3)] who underwent PCI or had medically managed ACS between August 2018 and December 2020 were identified by 68 cardiologists across eight provinces in Canada.

Race and Ethnicity With Atherosclerotic Cardiovascular Disease Outcomes Within a Universal Health Care System: Insights From the CARTaGENE Study.

Background: It remains unclear whether racial and ethnic disparities for atherosclerotic cardiovascular disease (ASCVD) persist within universal health care systems. We aimed to explore long-term ASCVD outcomes within a single-payer health care system with extensive drug coverage in Québec, Canada.

Methods: CARTaGENE (CaG) is a population-based prospective cohort study of individuals aged 40 to 69 years.

Pharmacogenetics-guided dalcetrapib therapy after an acute coronary syndrome: the dal-GenE trial.

Aims: In a retrospective analysis of dal-Outcomes, the effect of dalcetrapib on cardiovascular events was influenced by an adenylate cyclase type 9 (ADCY9) gene polymorphism. The dal-GenE study was conducted to test this pharmacogenetic hypothesis.

Methods And Results: dal-GenE was a double-blind trial in patients with an acute coronary syndrome within 1-3 months and the AA genotype at variant rs1967309 in the ADCY9 gene.

Colchicine for Prevention of Atherothrombotic Events in Patients With Coronary Artery Disease: Review and Practical Approach for Clinicians.

A better understanding of the central role of inflammation in the development of coronary artery disease (CAD) has been the impetus for the evaluation of therapeutic strategies targeting the interleukin-1ß/interleukin-6 cytokine signaling pathway, involved in both chronic atherogenesis and in triggering of atherosclerotic plaque rupture. As an inexpensive pharmacologic agent with relatively few adverse effects that tend to be mild and tolerable, the role of colchicine in secondary prevention of atherothrombotic events has been the focus of multiple recent large-scale randomized controlled trials involving patients with stable CAD (Low-Dose Colchicine [LoDoCo] and LoDoCo2 trials), a recent myocardial infarction (Colchicine Cardiovascular Outcome Trial [COLCOT], Colchicine in Patients With Acute Coronary Syndrome [COPS], and Colchicine and Spironolactone in Patients With Myocardial Infarction/Synergy Stent Registry [CLEAR SYNERGY] trials), and undergoing percutaneous coronary interventions (Colchicine in Percutaneous Coronary Intervention [COLCHICINE-PCI] trial). Based on this evidence, low-dose colchicine (0.

Colchicine for community-treated patients with COVID-19 (COLCORONA): a phase 3, randomised, double-blinded, adaptive, placebo-controlled, multicentre trial.

Background: Evidence suggests a role for excessive inflammation in COVID-19 complications. Colchicine is an oral anti-inflammatory medication beneficial in gout, pericarditis, and coronary disease. We aimed to investigate the effect of colchicine on the composite of COVID-19-related death or hospital admission.

Evaluation and Management of Dyslipidemia in Patients Treated with Lorlatinib.

The use of lorlatinib, an anaplastic lymphoma kinase (ALK) inhibitor for the treatment of -positive metastatic non-small cell lung cancer, is associated with dyslipidemia in over 80% of patients. Clinical trial protocols for the management of lorlatinib-associated dyslipidemia differ from clinical practice guidelines for the management of dyslipidemia to prevent cardiovascular disease, in that they are based on total cholesterol and triglyceride levels rather than on the low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol levels that form the basis of current cardiovascular guideline recommendations. In order to simplify and harmonize the management of cardiovascular risk in patients with lorlatinib, an advisory committee consisting of a medical oncologist, a cardiologist, and two pharmacists with expertise in cardiology and oncology aimed to develop a simplified algorithm, adapted from the Canadian Cardiovascular Society dyslipidemia recommendations.

Landscape of Lipid Management Following an Acute Coronary Syndrome Event: Survey of Canadian Specialists.

Background: Following the occurrence of an acute coronary syndrome (ACS), patients are at high risk for subsequent cardiovascular events. Therapies to lower the level of low-density lipoprotein (LDL) cholesterol remain a pillar in secondary prevention approaches following ACS. Significant variability remains in the application of therapies to lower cholesterol level in clinical practice.

Optimizing screening and management of cardiovascular health in prostate cancer: A review.

In clinical practice, cancer management does not consistently encompass screening and identification of cardiovascular (CV) risk. The use of androgen deprivation therapy (ADT) in prostate cancer has been associated with increased CV risk and development of metabolic syndrome, necessitating identification of patients at risk in this population (e.g.

Cost-effectiveness of low-dose colchicine after myocardial infarction in the Colchicine Cardiovascular Outcomes Trial (COLCOT).

Aims: In the randomized, placebo-controlled Colchicine Cardiovascular Outcomes Trial (COLCOT) of 4745 patients enrolled within 30 days after myocardial infarction (MI), low-dose colchicine (0.5 mg once daily) reduced the incidence of the primary composite endpoint of cardiovascular death, resuscitated cardiac arrest, MI, stroke, or urgent hospitalization for angina leading to coronary revascularization. To assess the in-trial period and lifetime cost-effectiveness of low-dose colchicine therapy compared to placebo in post-MI patients on standard-of-care therapy.

Efficacy and Safety of Low-Dose Colchicine after Myocardial Infarction.

Background: Experimental and clinical evidence supports the role of inflammation in atherosclerosis and its complications. Colchicine is an orally administered, potent antiinflammatory medication that is indicated for the treatment of gout and pericarditis.

Methods: We performed a randomized, double-blind trial involving patients recruited within 30 days after a myocardial infarction.

Simplified Canadian Definition for Familial Hypercholesterolemia.

Familial hypercholesterolemia (FH) is an autosomal codominant lipoprotein disorder characterized by elevated low-density lipoprotein cholesterol (LDL-C) and high risk of premature atherosclerotic cardiovascular disease. Definitions for FH rely on complex algorithms that are on the basis of levels of total or LDL-C, clinical features, family history, and DNA analysis that are often difficult to obtain. We propose a novel simplified definition for FH.

Effect of treatment with 5-lipoxygenase inhibitor VIA-2291 (atreleuton) on coronary plaque progression: a serial CT angiography study.

Background: Inflammation has a key role in the process of atherosclerosis. Production of leukotrienes by 5-lipoxygenase has been linked to atherosclerotic plaques and cardiovascular events.

Hypothesis: In this study, a selective 5-LO inhibitor will slow plaque progression using serial cardiac computed tomographic angiography (CCTA).

Genotype-Dependent Effects of Dalcetrapib on Cholesterol Efflux and Inflammation: Concordance With Clinical Outcomes.

Background: Dalcetrapib effects on cardiovascular outcomes are determined by adenylate cyclase 9 gene polymorphisms. Our aim was to determine whether these clinical end point results are also associated with changes in reverse cholesterol transport and inflammation.

Methods And Results: Participants of the dal-OUTCOMES and dal-PLAQUE-2 trials were randomly assigned to receive dalcetrapib or placebo in addition to standard care.

Hypertension Canada's 2016 Canadian Hypertension Education Program Guidelines for Blood Pressure Measurement, Diagnosis, Assessment of Risk, Prevention, and Treatment of Hypertension.

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.

The Benefits Conferred by Radial Access for Cardiac Catheterization Are Offset by a Paradoxical Increase in the Rate of Vascular Access Site Complications With Femoral Access: The Campeau Radial Paradox.

Objectives: The purpose of this study was to assess whether the benefits conferred by radial access (RA) at an individual level are offset by a proportionally greater incidence of vascular access site complications (VASC) at a population level when femoral access (FA) is performed.

Background: The recent widespread adoption of RA for cardiac catheterization has been associated with increased rates of VASCs when FA is attempted.

Methods: Logistic regression was used to calculate the adjusted VASC rate in a contemporary cohort of consecutive patients (2006 to 2008) where both RA and FA were used, and compared it with the adjusted VASC rate observed in a historical control cohort (1996 to 1998) where only FA was used.
