Key result
Early coronarography in patients with NSTEMI reduced the number of days of hospitalization but did not influence the rate of complications or short- and medium-term mortality.
Why the study?
While guidelines recommend timing coronarography based on risk groups, no consensus had been reached regarding the benefit of an invasive approach versus recommendations in NSTEMI.
Does the timing of coronarography influence complications, hospitalization duration, and mortality in patients with NSTEMI?
Population

Comparison
Timing of coronarography (<2 hours vs 24 hours vs 24-72 hours vs >72 hours)
Design
Observational cohort study

Does the timing of coronarography influence complications, hospitalization duration, and mortality in patients with NSTEMI?
Absolute Event Rate: 5.92% vs 10.28%
Early coronarography in NSTEMI patients reduces the length of hospital stay but does not significantly impact complication rates or 1-year mortality compared to delayed procedures.
Cozma et al. (2020) conducted a cohort in Myocardial infarction without ST-segment elevation (NSTEMI) (n=125). Time of coronarography vs. Late coronarography (>72 hours) was evaluated on Number of hospitalization days. Early coronarography in patients with NSTEMI reduced the number of days of hospitalization but did not influence the rate of complications or short- and medium-term mortality.
