Does nonobstructive CAD increase the 1-year risk of MI and all-cause mortality in patients undergoing elective coronary angiography?
Nonobstructive CAD found during elective angiography is not benign and carries a significantly increased 1-year risk of MI and mortality compared to no apparent CAD.
In this cohort of patients undergoing elective coronary angiography, nonobstructive CAD, compared with no apparent CAD, was associated with a significantly greater 1-year risk of MI and all-cause mortality. These findings suggest clinical importance of nonobstructive CAD and warrant further investigation of interventions to improve outcomes among these patients.
