What biomarker is useful for differentiating acute decompensated heart failure as a cause of chest pain or dyspnea?

Natriuretic peptides released in response to ventricular stretch help distinguish heart failure–related dyspnea from other causes. In acute decompensated heart failure, the impaired heart and fluid overload stretch the ventricles, prompting release of BNP and its precursor NT-proBNP. Elevated levels reliably indicate cardiac wall stress and support the diagnosis of HF when used alongside clinical assessment and imaging. Troponin measures myocardial injury and is more about detecting ischemia; it isn’t specific for differentiating HF as the cause of chest pain or dyspnea. D-dimer points to thromboembolic processes, and CRP reflects inflammation—neither is as helpful for confirming HF as BNP or NT-proBNP.
