Coronary artery calcium scoring (CAC) may augment traditional cardiovascular (CV) risk factor assessment and guide the use of appropriate preventative therapies. The impact of CAC on medication adherence, CV events, clinic visits and total costs in patients with CV risk factors (RF) is unknown.
We reviewed all patients who underwent CAC in a large community hospital setting from 1999 to 2012. Treatment therapy, CV events (coronary artery bypass graft, percutaneous coronary intervention, acute myocardial infarction), and cardiology costs were compared between CAC=0 and CAC>0 patients having ≥2 RFs. RFs were defined as male gender, diabetes, hypertension, hyperlipidemia, and tobacco use. Optimal medical therapy was defined as aspirin in diabetics and statin therapy in patients with diagnosed hyperlipidemia.
Among 11,538 patients with a CAC score, 1,668 (14.5%) had ≥2 RFs and available electronic health record follow-up. Median follow-up was 5.0 years and 2.1 years for CAC=0 and CAC>0 patients, respectively. Preventive medication utilization, optimal therapy for RFs, CV events, and CV costs were statistically significantly higher in patients with CAC>0 (Table).
The finding of CAC changes management, leading to increased use of preventive medicines in patients with multiple RFs. Presence of any CAC was associated with similar outpatient visit volumes, and higher total CV costs driven by higher inpatient CV event rates.
