Treatment Gap in Primary Prevention Patients Presenting With Acute Coronary Syndrome.

Previous studies assessing healthcare provider compliance to the 2013 American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines indicate a significant underuse of statin therapy at appropriate intensity. However, data are limited in primary prevention patients. Our study aimed to evaluate the impact of the 2013 ACC/AHA guidelines through a retrospective analysis of primary prevention patients presenting with first time acute coronary syndrome (ACS). We retrospectively calculated the 10-year predicted Atherosclerotic Cardiovascular Disease (10yASCVD) risk in 1,265 patients ages 40 to 75 who presented with ACS and no previous ASCVD. In patients without known ambulatory systolic blood pressure, a multivariable linear regression model was used to predict outpatient systolic blood pressure. Outcomes analyzed in each 10yASCVD category included statin status and statin intensity (high/medium/low) with further categorization by type of ACS event and date of left heart catheterization. In both primary analysis and sensitivity analysis (patients with predicted systolic blood pressure), statistical significance was shown with respect to overall statin status, ST Elevation Myocardial Infarction, and date of left heart catheterization. In summary, retrospective calculation of 10yASCVD in patients with a first ACS event showed a significant number of ACS patients would have qualified for statin therapy per 2013 ACC/AHA guidelines before their event but had not been initiated on one.
