Invasive vs conservative management in elderly patients with NSTEMI- insights from the SENIOR-RITA trial

The SENIOR-RITA trial randomized 1,518 elderly Non-ST-segment elevation myocardial infarction (NSTEMI) patients to invasive or conservative strategies. The primary composite outcome of cardiovascular death or nonfatal Myocardial Infarction (MI) occurred in 25.6% of the invasive group versus 26.3% in the conservative group (p = 0.53), despite lower nonfatal MI rates with invasive treatment (11.7% vs 15.0%). Procedural complications were low (< 1%), though the invasive group had slightly higher bleeding and Transient Ischemic Attack (TIA) rates. The early 1-year benefit of the invasive approach was not maintained at 5 years, highlighting the need to individualize management in this complex, elderly population. The review discusses the strengths and weaknesses of the SENIOR-RITA (Older Patients with Non–ST-Segment Elevation Myocardial Infarction Randomized Interventional Treatment) trial.
