Background In 2016, the National Institute for Health and Care Excellence Clinical Guideline Number 95 (“Chest pain of recent onset”) (CG95 recommended coronary computed tomography angiography (CCTA) as the first-line for possible angina.
Objectives The purpose of this study was to determine the impact of temporal trends in imaging use of outcome for coronary artery disease (CAD) following the CG95 recommendations.
Results
There was a rise in CCTA, decrease in myocardial perfusion imaging, and a modest fall in invasive coronary angiography. There was an apparent trend between computed tomography angiography growth and invasive catheter angiography reduction across regions.
CCTA growth was associated with a reduction in cardiovascular mortality, and ischemic heart disease deaths with an apparent trend with reduced all-cause mortality.
Conclusions
Imaging investigations for CAD are increasing. Greater regional increases in CCTA were associated with fewer hospitalizations for myocardial infarction and a more rapid decline in CAD mortality.
