Elevated Troponin

What else can cause myocardial necrosis (and elevated serum markers) besides coronary artery disease?

Although elevated serum markers indicate myocardial necrosis, they provide no insight into its cause. In some patients, myocardial necrosis is caused by disorders other than coronary artery disease (e.g., pulmonary embolism, decompensated heart failure, severe hypertension or tachycardia, anemia, and sepsis). During evaluation of a patient with a possible acute coronary syndrome, the presence of elevated serum markers should be assessed in conjunction with other variables to provide insight into its most likely cause.
