[Acute coronary syndrome and coronariography without significant lesions: do we know everything?].

Obstructive coronary artery disease is not detected in up to 14% of patients who present with acute coronary syndrome (ACS). Diagnosis of the underlying cause is usually not made and there is much controversy regarding prognosis. Those patients who develop ACS while having normal or near normal coronary arteries are more frequently young women and have fewer cardiovascular risk factors (CVRF). Its prognosis has typically been excellent. However, different results published in recent years show that these conditions are not always so benign. This might be explained by the different degrees of coronary obstruction, varied clinical presentation, biomarkers' mobilization or CVRF. It is necessary to determine the cause of ACS and stratify the risk of these patients in order to establish the appropriate treatment. This is especially relevant in those cases of coronary disease not detected by angiography, in which the absence of specific treatment can lead to poorer prognosis.
