Implication
Supports tailored NSTE-ACS strategies; leaves open optimal implementation pending prospective trials.
Key Points
- To review the spectrum of non-ST-segment elevation acute coronary syndrome and evaluate strategies for diagnostic evaluation, risk stratification, and patient-tailored revascularization.
- Synthesized evidence from randomized clinical trials, clinical registries, and administrative databases.
- Evaluated diagnostic pathways encompassing symptoms, electrocardiography, cardiac troponin, and differential diagnoses including type 2 myocardial infarction and myocardial infarction with non-obstructive coronary arteries.
- Assessed management strategies spanning early invasive angiography, complete versus culprit-only revascularization, and tailored post-acute antithrombotic regimens.
- Early invasive strategies reduce recurrent myocardial infarction and urgent revascularization across randomized clinical trials, while registry data associate higher revascularization rates with reduced mortality.
- Complete revascularization in patients with multivessel disease reduces mortality compared with culprit-only revascularization, maintaining safety across fragile, elderly, and multimorbid populations.
- Accurate initial risk stratification relies on exclusion of secondary causes of myocardial injury and guides individualized secondary prevention.
