Seguridad y experiencia en el uso del oxígeno hiperbárico en el paciente con infarto agudo al miocardio con elevación del ST

Hyperbaric oxygen (HBO2) is a useful treatment for ischemic diseases; however, as an adjuvant treatment in myocardial infarction (MI), there is very little experience worldwide. It has been used in some research work as a single treatment in a single exposure in the context of an ST-segment elevation myocardial infarction (STEMI) and in addition to thrombolysis. Our study describes the feasibility and safety of continuous doses of HBO2 after a heart attack by improving left ventricular function. Objective: The objective of this study is to describe the experience and safety of HBO2 doses in the patient with STEMI taken to primary angioplasty to improve left ventricular function. Material and methods: 24 randomized patients were collected and divided into two groups: 13 in the case group and 11 control patients. Both groups were taken to primary angioplasty and conventional treatment. Left ventricular function was assessed with SPECT CT; the case group received 15 repeated 90-minute sessions of isopressure at 2.0 ATA. Results: The two groups were similar in characteristics; they were admitted to the hospital with an STEMI, taken to primary angioplasty, randomized into two groups. The group of cases was taken to the hyperbaric chamber to receive daily doses of HBO2 for 15 days at 2 ATA for 90 minutes of isopressure. There were no cardiovascular complications during the treatment with hyperbaric oxygen: reinfarction, bleeding, hypertensive disorder, arrhythmias or heart failure data. Complications typical of the hyperbaric chamber: only one patient presented signifi cant claustrophobia. In addition to the benefi ts of the conventional treatment of STEMI, the left-ventricular ejection fraction (LVEF) in anteroseptal MI was signifi cantly improved in the group of cases. Conclusions: Continuous-dose hyperbaric oxygen is safe and feasible as an additional treatment for patients with STEMI taken to primary angioplasty, in addition to improving left ventricular function in extensive heart attacks. El oxígeno hiperbárico (HBO2) es un tratamiento útil para enfermedades isquémicas; sin embargo, como tratamiento coadyuvante en el infarto al miocardio (IAM), existe muy poca experiencia a nivel mundial; ha sido utilizado en algunos trabajos de investigación como tratamiento único en una sola exposición en el contexto de un infarto agudo con elevación del segmento ST (IAMCEST) y adicional a la trombólisis.
