Novos tipos de dispositivos mec\u00e2nicos t\u00eam limitada disponibilidade em nosso meio. O uso de bal\u00e3o intra-a\u00f3rtico (BIA), apesar da indica\u00e7\u00e3o rebaixada em novas diretrizes, constitui a estrat\u00e9gia de suporte mec\u00e2nico mais empregada. Entretanto, os preditores cl\u00ednicos de sua efetividade na redu\u00e7\u00e3o de morte nesse grupo s\u00e3o pouco conhecidos.  Objetivos  Avaliar os preditores de efetividade do BIA na redu\u00e7\u00e3o da mortalidade intra-hospitalar de pacientes com IAMCSST e CC.  M\u00e9todos  Estudo observacional, retrospectivo, descritivo, unic\u00eantrico, envolvendo 98 pacientes com IAMCSST e CC que utilizaram BIA, na unidade de terapia intensiva. Comparamos os pacientes que sobreviveram (42 homens e 13 mulheres) ou n\u00e3o (30 homens e 13 mulheres) atrav\u00e9s dos preditores cl\u00ednicos de efetividade do BIA na redu\u00e7\u00e3o de morte intra-hospitalar, considerando um n\u00edvel de signific\u00e2ncia estat\u00edstica de 5% (p &lt; 0,05).  Resultados  O emprego de BIA em pacientes com menos de um dia de infarto (odds ratio [OR]: 0,12; intervalo de confian\u00e7a [IC] de 95%: 0,02 a 0,85; p = 0,034) constituiu fator de aumento do risco de morte intra-hospitalar. Pacientes mais jovens (OR: 1,09; IC 95%: 1,02 a 1,16; p = 0,010) e dislipid\u00eamicos (OR: 0,19; IC 95%: 0,05 a 0,81; p = 0,024) constitu\u00edram preditores de redu\u00e7\u00e3o de morte intra-hospitalar. A cada ano a mais na idade, o risco de \u00f3bito aumentou 1,07 vezes.  Conclus\u00e3o  Em pacientes com IAMCSST e CC, o uso de BIA reduziu mortalidade intra-hospitalar quando foi utilizado por 2 ou mais dias e em pacientes mais jovens e dislipid\u00eamicos. Estudos adicionais s\u00e3o necess\u00e1rios para confirmar esses achados.<\/jats:p>","DOI":"10.36660\/abc.20230496","type":"journal-article","created":{"date-parts":[[2025,3,25]],"date-time":"2025-03-25T13:53:16Z","timestamp":1742910796000},"source":"Crossref","is-referenced-by-count":0,"title":["Preditores de Mortalidade Intra-Hospitalar de Pacientes com Infarto Agudo do Mioc\u00e1rdio com Choque Cardiog\u00eanico em Uso de Bal\u00e3o Intra-A\u00f3rtico"],"prefix":"10.36660","volume":"122","author":[{"given":"Rossana Dall\u2019Orto","family":"Elias","sequence":"first","affiliation":[{"name":"Biocor Instituto,  Brasil; Faculdade de Ci\u00eancias M\u00e9dicas de Minas Gerais,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabella Pedrosa","family":"Assun\u00e7\u00e3o","sequence":"additional","affiliation":[{"name":"Biocor Instituto,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julliane Vasconcelos Joviano","family":"Santos","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias M\u00e9dicas de Minas Gerais,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria da Gloria","family":"Rodrigues-Machado","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias M\u00e9dicas de Minas Gerais,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8920-5173","authenticated-orcid":false,"given":"Jos\u00e9 Luiz Barros","family":"Pena","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias M\u00e9dicas de Minas Gerais,  Brasil; Hospital Felicio Rocho,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"22636","published-online":{"date-parts":[[2025]]},"reference":[{"issue":"14","key":"ref1","doi-asserted-by":"crossref","first-page":"1287","DOI":"10.1056\/NEJMoa1208410","article-title":"Intraaortic Balloon Support for Myocardial Infarction with Cardiogenic Shock","volume":"367","author":"Thiele H","year":"2012","journal-title":"N Engl J Med"},{"issue":"9","key":"ref2","doi-asserted-by":"crossref","first-page":"1211","DOI":"10.1161\/CIRCULATIONAHA.108.814947","article-title":"Thirty-year Trends (1975 to 2005) in the Magnitude of, Management of, and Hospital Death Rates Associated with Cardiogenic Shock in Patients with Acute Myocardial Infarction: A Population-based Perspective","volume":"119","author":"Goldberg RJ","year":"2009","journal-title":"Circulation"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","DOI":"10.1161\/JAHA.113.000590","article-title":"Trends in Incidence, Management, and Outcomes of Cardiogenic Shock Complicating ST-Elevation Myocardial Infarction in the United States","volume":"3","author":"Kolte D","year":"2014","journal-title":"J Am Heart Assoc"},{"issue":"4","key":"ref4","doi-asserted-by":"crossref","first-page":"e47","DOI":"10.1016\/j.hlc.2018.03.025","article-title":"Trends in the Utilisation and In-Hospital Mortality Associated with Short-term Mechanical Circulatory Support for Heart Failure with Reduced Ejection Fraction","volume":"28","author":"Doshi R","year":"2019","journal-title":"Heart Lung Circ"},{"issue":"4","key":"ref5","doi-asserted-by":"crossref","first-page":"287","DOI":"10.1007\/s00392-017-1182-2","article-title":"Trends in Mechanical Circulatory Support Use and Hospital Mortality among Patients with Acute Myocardial Infarction and Non-infarction Related Cardiogenic Shock in the United States","volume":"107","author":"Shah M","year":"2018","journal-title":"Clin Res Cardiol"},{"issue":"6","key":"ref6","first-page":"346","article-title":"Haemodynamic Effects of the Use of the Intraaortic Balloon Pump","volume":"48","author":"Parissis H","year":"2007","journal-title":"Hellenic J Cardiol"},{"issue":"6","key":"ref7","doi-asserted-by":"crossref","first-page":"578","DOI":"10.1097\/MAT.0b013e318186891f","article-title":"Acute Hemodynamic Efficacy of a 32-ml Subcutaneous Counterpulsation Device in a Calf Model of Diminished Cardiac Function","volume":"54","author":"Koenig SC","year":"2008","journal-title":"ASAIO J"},{"issue":"3","key":"ref8","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1016\/j.ijcard.2008.08.015","article-title":"Increase in Coronary Blood Flow by Intra-aortic Balloon Counterpulsation in a Porcine Model of Myocardial Reperfusion","volume":"138","author":"Bonios MJ","year":"2010","journal-title":"Int J Cardiol"},{"issue":"1","key":"ref9","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1002\/ccd.20552","article-title":"Aortic Counterpulsation: A Review of the Hemodynamic Effects and Indications for Use","volume":"67","author":"Santa-Cruz RA","year":"2006","journal-title":"Catheter Cardiovasc Interv"},{"issue":"2","key":"ref10","doi-asserted-by":"crossref","first-page":"52","DOI":"10.1016\/j.vph.2013.12.003","article-title":"Intra-aortic Balloon Counterpulsation -
