Mean age was 66\u00b19\u2009years. The cohort was predominantly male (77%); 66% had hypertension, and 22% had diabetes. Vessel\u2010specific myocardial mass was calculated for 2767 main epicardial arteries (948 left anterior descending, 948 left circumflex, and 871 right coronary artery) and 6461 side branches (1888 diagonals, 1208 septals, 1422 obtuse marginals, 247 ramus intermedius, 850 right posterior descending, and 846 posterolateral branches). Median LV mass was 141 grams (interquartile range 118\u2013166); women had smaller LV mass than men (106 [93\u2013123] grams versus 150 [132\u2013173] grams,\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      &lt;0.001).

Median LV mass subtended by the first septal, first diagonal, and first obtuse marginal were 8.9% [6.4\u201311.1], 7.9% [4.52\u20132.0], and 10.2% [4.52\u201312.0], respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">This study quantified the myocardial mass subtended by each major artery in the coronary circulation.
