Invasive Versus Conservative Strategy in Frail Patients With NSTEMI: The MOSCA-FRAIL Clinical Trial Study Design.

Introduction And Objectives: Although clinical guidelines recommend invasive management in non-ST-segment elevation myocardial infarction (NSTEMI), this strategy is underused in frail elderly patients in the real world. Furthermore, these patients are underrepresented in clinical trials and therefore the evidence is scarce. Our hypothesis is that an invasive strategy will improve prognosis in elderly frail patients with NSTEMI.

[Anomalous coronary arteries originating in the contralateral sinus of Valsalva: registry of thirteen Spanish hospitals (RACES)].

The registry contains information collected during 2003 from thirteen Spanish hospitals on the incidence, clinical presentation, initial course, diagnostic imaging, and treatment of anomalous coronary arteries originating in the contralateral coronary sinus. In a total of 23,300 coronary angiograms, 98 anomalous coronary arteries were detected (incidence 0.4%): 46 circumflex coronary arteries (47%), 25 right coronary arteries (25.
