Abstract
Abstract A 53–year–old woman presented herself at our center for the appearance of oppressive chest pain radiating to the upper limbs associated with cold sweat, which arose in resting conditions. The patient had as cardiovascular risk factors tobacco habits and an important family history of cardiovascular diseases (father died of AMI at a young age) and had entered menopause for some months. The ECG showed signs of anterior transmural ischemia (Figure 1a) with corresponding echocardiographic kinetic abnormalities of the cardiac apex (EF 40%). The patient underwent an emergency coronary angiography documenting an intramyocardial bridge with evident systolic squeezing of the vessel in the proximal–middle section of the anterior descending artery and normal appearance of the remaining coronary tree (Figure 2). She was subjected to infusion of intracoronary nitrates with improvement of the instrumental picture and on that occasion it was opted for medical therapy alone with double antiplatelet therapy and low–dose calcium antagonist. On the second day after the diagnostic procedure, there was a recurrence of anginal symptoms with evidence on the ECG of anterolaterally reversed T waves (figure 1b). The patient underwent a new coronary angiography, IVUS–guided, with documentation of probable intramural hematoma in the absence of non–flow–limiting dissection image with an area of 7 mm² (Figure 3). During the subsequent hospitalization, the patient remained asymptomatic with stable ECG tracing, but telemetry revealed ventricular tachyarrhythmias for which beta–blocker therapy was optimized with improvement of the arrhythmic burden. The pre–discharge echocardiogram showed improvement of cardiac kinesis with resumption of systolic function (EF 48%). The patient was discharged stable and asymptomatic with follow–up at our dedicated ischemic heart disease clinic. This case report is an example of an infrequent cause of acute coronary syndrome, of non–atherosclerotic origin, to be considered in clinical practice.
