Limitations One limitation in the implementation and expansion of this observational, registry-based study is the absence of integration between electronic medical records and database, which causes increased workload and, eventually, the need for dedicated research staff during patient care. The evaluation of clinical registry data should also consider the need for informed consent in data collection, which jeopardizes the inclusion of all eligible patients in the event of one single negative participation. It should also consider the possibility of a change of behavior because of the patient's awareness of their participation in a study, even if observational (Hawthorne effect). 27 Conclusion In this study, we described the logistics and systematics of developing a clinical registry of STEMI patients in the digital platform REDCap, adapted from an existing clinical registry. This data may be useful for institutions planning to elaborate new registries or improve existing ones. The standardization of registry operation and the use of dedicated databases allow to optimize this tool in terms of quality and speed of implementation. The use of similar systems can also make sharing information across institutions easier as well as assist the development of new health technologies and in the decision making of public policies regarding cardiovascular disease.
