Why the study?
Quality improvement initiatives for acute coronary syndrome were developed largely in high-income countries, and evidence of their effect on clinical outcomes and care processes was needed for potential implementation in low- and middle-income settings.

QI interventions improve ACS processes without cutting 30-day mortality; challenges reliance on process metrics as outcome surrogates.
