Increasing left main coronary artery plaque burden was associated with long-term all-cause and cardiac mortality in patients who did not have revascularization, even if the lumen area was preserved, researchers reported.
The researchers analyzed 3,239 patients (mean age, 66 years; 65% men) who had IVUS imaging of the left main coronary artery (LMCA) without revascularization from 2005 to 2013.
“The relationship between the presence of subclinical LMCA disease with preserved lumen dimensions on long-term mortality is unknown,” Masahiko Noguchi, MD, PhD, chief physician in
