Background: The burden of acute coronary syndrome (ACS) and heart failure (HF) remains high in Saudi Arabia. Biomarkers can greatly improve the management and outcomes of these conditions, but no official guidance is available on their use in Saudi Arabia. Consensus panel: An expert panel of cardiologists, interventional cardiologists and cardiac surgeon reviewed available evidence and formulated recommendations relevant to clinical practice in Saudi Arabia. Consensus findings: high-sensitivity cardiac troponins play a major role in the diagnosis of ACS and the exclusion of myocardial infarction in patients with HF. Natriuretic Peptides are recommended to determine the likelihood of a diagnosis of HF in a chronic setting and rapidly exclude HF in an acute setting. High-sensitivity cardiac troponins and NT-proBNP have good prognostic ability in ACS and HF. These biomarkers could also facilitate discharge planning and reduce unnecessary hospital admissions and resource wastage. The use of biomarkers should not be excessive and should abide by appropriateness criteria. High-sensitivity assays and NT-proBNP measurements are preferred. Conclusion: By outlining expert recommendations on the best practices in the use of biomarkers, the panel hopes to contribute towards a recognized updated guidance for all healthcare providers in Saudi Arabia on the evidence-based management of HF and ACS.
