RESUMEN
Left ventricular assist device (LVAD) implantation results in superior survival rates compared with optimal medical therapy in patients with end-stage heart failure. However, a potential complication of LVAD implantation is right heart failure (RHF), which can be devastating. Therefore, identifying preoperative risk factors for RHF and optimal management for these patients are critical for ensuring favorable postoperative outcomes. This review focuses on methods of assessing the risk factors for RHF before surgery, including evaluation of biomarkers, echocardiography, hemodynamics, risk-scoring systems, and existing conditions of right heart dysfunction. In addition, the review also explores the perioperative strategic approaches to reducing the likelihood of RHF.

OBJECTIVE: This meta-analysis aimed to review the available evidence and evaluate the necessity of immediate coronary angiography (CAG) to obtain positive outcomes for out-of-hospital cardiac arrest (OHCA) patients without ST segment elevation. DATA SOURCES: Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed databases. STUDY SELECTION: We included observational and case-control studies of outcomes among individuals without ST segment elevation experiencing OHCA who had immediate, delayed, or no CAG. DATA EXTRACTION: We extracted study details, as well as patient characteristics and outcomes. DATA SYNTHESIS: Six studies (nâ=â2665) investigating mortality until discharge demonstrated a significant increase in survival benefit with early CAG (odds ratio [OR]â=â1.78; 95%CIâ=â1.51-2.11; Iâ=â81%; Pâ<â.0001). Seven studies (nâ=â2909) showed a significant preservation of neurological functions with early CAG at discharge (ORâ=â1.66; 95%CIâ=â1.37-2.02; Pâ<â.00001). Four studies (nâ=â1357) investigating survival outcomes with middle-term follow-up revealed no significant benefit with early CAG (ORâ=â1.21; 95%CIâ=â0.93-1.57; Iâ=â66%; Pâ=â.15). CONCLUSIONS: Our meta-analysis demonstrates that there may be significant benefits in performing immediate CAG on patients who experience OHCA without ST segment elevation.
