Conclusion Geriatric syndromes are important prognostic factors for postoperative complications .
Background Elective surgeries can be associated with significant harm to older adults .
The present study aim ed to identify the prognostic factors associated with the development of postoperative complications among older adults undergoing elective surgery .
Age and sex differences in perioperative myocardial infarction after cardiac surgery.
We investigate age and sex differences in  acute myocardial infa rct ion ( AMI ) after cardiac surgery  in a prospect i ve study of 2038 consecutive patients undergoing cardiac surgery with cardiopulmonary bypass .  An age of ≥ 70 years implied changes in the type of AMI from the ST-segment elevation myocardial infa rct ion ( STEMI ) to non-ST-segment elevation myocardial infa rct ion ( non-STEMI ) . Men were more likely than women to suffer from AMI after cardiac surgery ( 11.8 % vs. 5.6 % ) , as a result of the higher frequency of STEMI ( 6 % of men vs. 1.8 % of women ; P < 0.001 ) in both age groups . A troponin-I ( Tn-I ) peak was significantly higher in patients ≥ 70 years old . In-hospital mortality was higher in patients ≥ 70 ( 7.3 % ) than in those < 70 years old ( 3.3 % ) , because of the increased mortality observed in men with non-AMI ( 2.1 % vs. 6.3 % ) and women with STEMI ( 0 % vs. 28.6 % ) and non-STEMI ( 0 % vs. 36.8 % , P < 0.05 ) . Old age was associated with a higher frequency of non-STEMI , Tn-I peak , mortality and length of stay in the intensive care unit ( ICU ) . Regardless of age , men more often suffer from AMI ( particularly STEMI ) . AMI in women had a notable impact on excess mortality and ICU stay observed in patients ≥ 70 years of age . Clinical and Tn-I peak differences are expected in relation to age and gender after AMI post-cardiac surgery
