Using CCTA for CAD diagnosis reduces mortality and MI hospitalization: Study

The study revealed the following findings:

• One million nine hundred nine thousand three hundred fourteen investigations were performed for CAD, with an annualized per capita growth of 4.8%.
• Costs were £0.35 million/100,000 population/year with a rise of 2.8%/year mirroring inflation (2.5%/year).
• CG95 was associated with an increase in CCTA (exp[β]: 1.10), no change in myocardial perfusion imaging, and a potential modest fall (exp[β]: 0.997) in invasive coronary angiography.
• There was an apparent trend between computed tomography angiography growth and reduction in invasive catheter angiography across regions (Kendall Tau: −0.19).
• CCTA growth was associated with a reduction in cardiovascular mortality (Kendall Tau: −0.21) and ischemic heart disease deaths (Kendall Tau: −0.22), with an apparent trend with reduced all-cause mortality (Kendall Tau: −0.19).

"Imaging investigations for CAD are increasing," researchers wrote. "Greater regional increases in CCTA were associated with a more rapid decline in CAD mortality and fewer hospitalizations for myocardial infarction."
