Prognostic benefit from an early invasive strategy in patients with non-ST elevation acute coronary syndrome (NSTEACS): evaluation of the new risk stratification in the NSTEACS European guidelines

Objectives The objective of our work is to evaluate the prognostic benefit of an early invasive strategy in patients with high-risk NSTACS according to the recommendations of the 2020 clinical practice guidelines during long-term follow-up. Methods This retrospective observational study included 6454 consecutive NSTEACS patients. We analyze the effects of early coronary angiography ( 140 and (b) patients with “established NSTEMI” (non ST-segment elevation myocardial infarction defined by an increase in troponins) or dynamic ST-T-segment changes with a GRACE risk score 140 [HR 0.62 (IC 95% 0.57–0.67), HR 0.62 (IC 95% 0.56–0.68), HR 0.57 (IC 95% 0.53–0.61), respectively]. In patients with NSTEACS and GRACE
