Subgroup analyses from randomized studies show inconsistent results regarding an early invasive approach in women with non-ST-elevation myocardial infarction (NSTEMI). We sought to investigate the impact of an invasive strategy in clinical practice, analyzing data from the German Acute Coronary Syndromes registry (ACOS).


Overall 1986 consecutive women were enrolled in the registry between June 2000 and November 2002 and were divided into two groups: 1215 (61.2%) underwent coronary angiography, 771 (38.8%) received conservative treatment. In the invasive group percutaneous coronary intervention was performed in 40.7% within 48 h and in 16.4% after 48 h, whereas 8.3% underwent coronary artery bypass grafting within hospital stay.


In-hospital death (3.2% vs 10.5%, p<0.0001), in-hospital death/myocardial infarction (MI) (7.1% vs 14.9%, p<0.0001) and one-year death (8.1% vs 24%) occurred significantly less often in patients with invasive strategy. After adjustment of the confounding factors in the propensity score analysis the invasive strategy showed no significant benefit for in-hospital death (OR 0.86, 95% CI 0.51-1.44) or death/MI (OR 0.70, 95% CI 0.47-1.04) but remained superior for mortality (OR 0.47, 95% CI 0.3-0.7) and death/MI one year after discharge (OR 0.47, 95% CI 0.33-0.68).


In clinical practice women presenting with NSTEMI have a long-term benefit from an invasive therapeutic strategy with a significant reduction in mortality as well as the composite endpoint of death/MI.
