Clinical trials vs. observational registries Carefully-conducted, observational registries reveal what we do in our daily practice. What we do, not what we know, impacts our patients outcomes. Randomized trials tell us about the efficacy of an agent/intervention in certain protected set up. Randomized trials cannot emulate daily practice.

Conclusions It is critical that we examine what we do. Gulf citizens with ACS are much younger than their European and North American peers, yet have a similar if not worse risk profile. They receive good medical therapy at discharge from hospital. The majority of hospitals do not have onsite cath labs and a minority of patients receive inhospital catheterization at those hospitals.
Conclusions In hospitals with onsite cath labs, majority of patient receive inhospital cath. However, the use of primary PCI is not widespread. When carried out, primary PCI was performed efficiently in terms of the door to balloon time. Lytic administration is still seeing unacceptable delay. Compared to 2007 Gulf RACE, there are positive signs.
