Impact of Zero Coronary Artery Calcium Scoring on Downstream Cardiac Testing and Cardiac Outcomes Compared With No Testing.

ABSTRACT:

Background

The impact of coronary artery calcium (CAC) scoring on downstream resource utilisation and outcomes remains unclear, especially in those with zero CAC.

Methods

Consecutive CAC scores from two academic hospitals in Toronto, Ontario, were linked to population-based databases. Subjects with zero CAC without previous cardiovascular disease were propensity score matched with a non-CAC-tested control group for age, sex, cardiovascular risk factors, and comorbidities. Downstream cardiac testing, acute myocardial infarction, heart failure (HF) hospitalisations, and HF emergency department (ED) visits were compared between the 2 groups.

Results

A total of 4884 patients underwent CAC scoring, of whom 2709 had zero CAC (mean 52.9 ± 10.6 years), 55.4% women. At 3.4 yea
