Aim
This study aimed to analyze guideline adherence in the timing of invasive management for myocardial infarction without persistent ST-segment elevation (NSTEMI) in two exemplary German centers, comparing an urban university maximum care facility and a rural regional primary care facility.
Methods
All patients diagnosed as having NSTEMI during 2013 were retrospectively enrolled in two centers: (1) site I, a maximum care center in an urban university setting, and (b) site II, a primary care center in a rural regional care setting. Data acquisition included time intervals from admission to invasive management, risk criteria, rate of intervention, and medical therapy.
Results
The median time from admission to coronary angiography was 12.0 h (site I) or 17.5 h (site II; p = 0.17). Guideline-adherent timing was achieved in 88.1 % (site I) or 82.9 % (site II; p = 0.18) of cases. Intervention rates were high in both sites (site I—75.5 % vs. site II—75.3 %; p = 0.85). Adherence to recommendations of medical therapy was high and comparable between the two sites.
Conclusion
In NSTEMI or high-risk acute coronary syndromes without persistent ST-segment elevation, guideline-adherent timing of invasive management was achieved in about 85 % of cases, and was comparable between urban maximum and rural primary care settings. Validation by the German Chest Pain Unit Registry including outcome analysis is required.
