Contact with general practice in patients with suspected chronic coronary syndrome before and after CT angiography compared with the general population
Authors' conclusion
In patients undergoing CCTA to diagnose CAD, a substantially increased frequency of contacts to GP was observed in the 5-year period prior to examination compared with the reference populations, regardless of the CCTA findings. Obtaining the CCTA result did not seem to substantially affect the GP visit frequency.
