Primary PCI at night time Int J Cardiovasc Sci. 2018;31(5)513-519 Original Article periods were comparable, showing similar mortality rates and incidence of major adverse cardiovascular events between the two groups. With logistic optimization and the prioritizing of immediate care in STEMI cases, it is possible to overcome the accessibility, availability and information barriers, which are extremely common in Brazilian metropolitan regions, especially at nighttime.
