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

ABSTRACT: 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.

Methods: A cross-sectional, online survey was conducted of 200 cardiovascular and lipid specialists across Canada who routinely care for patients following the occurrence of ACSs. The survey consisted of 50 multiple-choice questions with opportunities for free-text entry exploring knowledge of lipid guidelines and recent clinical trials, and in-hospital and outpatient management of lipids and familial hypercholesterolemia.

Results: A total of 67.5% (n = 135) of participants stated that a lipid panel would routinely be obtained during the first 24 hours of an admission for an ACS, and 68.5% (n = 137) stated that their hospitals had standing orders for statin initiation at ACS presentation. In high-risk patients, the majority (75.5%; n = 151) of participants indicated that they target an LDL cholesterol level of <1.8 mmol/L. However, a subset (22%; n = 44) would target lower LDL cholesterol levels ranging from 0.5 to 1.7 mmol/L. Only 32.0% (n = 64) of participants stated that >70% of their ACS patients were at or below guideline-recommended LDL cholesterol levels. Respondents generally underappreciated the prevalence of familial hypercholesterolemia in both the general population and ACS patients.

Conclusions: There is significant variation in practice patterns involving therapies to lower LDL cholesterol level in the post-ACS onset period. To improve management of lipids in this high-risk population, changes to institutional policies, shared responsibility of lipid management across multiple disciplines, and physician education are required.

Project description:PURPOSE:Severe asthma and asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) are difficult to control and are often associated with poor clinical outcomes. However, much is not understood regarding the diagnosis and treatment of severe asthma and ACOS. To evaluate the current perceptions of severe asthma and COPD among asthma and COPD specialists, we designed an e-mail and internet-based questionnaire survey. METHODS:Subjects were selected based on clinical specialty from among the members of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Academy of Tuberculosis and Respiratory Diseases. Of 432 subjects who received an e-mail invitation to the survey, 95 subjects, including 58 allergists and 37 pulmonologists, responded and submitted their answers online. RESULTS:The specialists estimated that the percentage of severe cases among total asthma patients in their practice was 13.9%±11.0%. Asthma aggravation by stepping down treatment was the most common subtype, followed by frequent exacerbation, uncontrolled asthma despite higher treatment steps, and serious exacerbation. ACOS was estimated to account for 20.7% of asthma, 38.0% of severe asthma, and 30.1% of COPD cases. A history of smoking, persistently low forced expiratory volume in 1 second (FEV1), and low FEV1 variation were most frequently classified as the major criteria for the diagnosis of ACOS among asthma patients. Among COPD patients, the highly selected major criteria for ACOS were high FEV1 variation, positive bronchodilator response, a personal history of allergies and positive airway hyperresponsiveness. Allergists and pulmonologists showed different assessments and opinions on asthma phenotyping, percentage, and diagnostic criteria for ACOS. CONCLUSIONS:Specialists had diverse perceptions and clinical practices regarding severe asthma and ACOS patients. This heterogeneity must be considered in future studies and strategy development for severe asthma and ACOS.
