GONZALEZ, Laura Duque et al. Pericardial tamponade associated with minoxidil: a forgotten diagnosis. Rev. Colomb. Cardiol. [online]. 2019, vol.26, n.6, pp.342-345. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2019.07.007.

Pericardial effusion is an excessive accumulation of fluid in the pericardial space and has been associated with the long-term use of minoxidil from the beginning of its clinical use. It is commonly prescribed to patients with difficult to control arterial hypertension and associated chronic kidney disease due to it arterial vasodilator effects and little effect of the venous circulation.

A case is presented on a patient who had a clinical picture suggestive of a pericardial effusion, which was confirmed by imaging tests (X-ray, tomography, and cardiac ultrasound). She was also on long-term haemodialysis treatment due to chronic kidney disease secondary to a nephrotic syndrome.

There are reports of similar cases in the literature, but there are no studies with conclusive data that may help to establish a clear percentage association or the cause of the disease.

This case report seeks to increase the diagnostic suspicion of this association so that other clinicians may have this possible diagnosis in mind, once they have ruled out any other. They can then stop the medication on time in order to prevent catastrophic outcomes like pericardiac tamponade.
