I very regularly treat patients like the one described. The workup required to rule out chest pain of cardiac etiology include bloodwork and depending on the condition, chest x-ray, ECHO, and other tests may be needed. The bloodwork includes the following: 1) cardiac biomarkers – troponins are the preferred test for the diagnosis of AMI. Creatine kinase MB (CK-MB) isoform levels rise too. 2) D – dimer – among patients with a low-pretest probability for pulmonary embolus (PE), a D-dimer test with high sensitivity can rule out the diagnosis, obviating the need for further testing. 3) Complete blood count – the white blood cell count may be elevated in any of the inflammatory or infectious etiologies of chest pain, such as myocarditis and pericarditis. 4) B-type natriuretic peptide (BNP) – when used in conjunction with other clinical information, natriuretic peptide concentrations can help to identify or exclude acute HF as the cause of dyspnea and chest pain. I teach my medical students and residents on a regular basis on this topic.
