The value of speckle tracking echocardiography in diagnosing minoxidil-induced cardiotoxicity: a case report.

Minoxidil is a drug designed for the treatment of arterial hypotension. Due to its secondary effect of hypertrichosis, it is also used for alopecia treatment. We present a case of a 50-year-old female patient who was orally consuming Minoxidil for medical reasons. She presented with severe hypotension, requiring vasoactive drugs, and evidence of myocardial injury was detected using speckle tracking echocardiography. It is worth noting that the patient did not have any coronary heart disease, and the myocardial injury was found to be associated with Minoxidil consumption. Remarkably, the patient showed signs of reversal 72 h after stopping the drug. To our knowledge, this is the first reported case of subendocardial injury associated with Minoxidil, using speckle tracking echocardiography. In the resolution of the case, it was essential to rule out differential diagnoses, administer vasopressors, and use the speckle tracking echocardiography, which allowed for the objective assessment of myocardial injury and the monitoring of the patient during their hospitalization.
