Compared with male patients, female patients were older (67.2 ± 9.4 vs. 65.3 ± 9.2 years; p = 0.003), had lower incidences of coronary artery disease and chronic obstructive pulmonary disease, had a higher EuroSCORE II and a lower hematocrit value, a higher proportion received angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and a lower proportion received beta blockers or clopidogrel. This evidence concerns the gene ACE and chronic obstructive pulmonary disease.
