Abstract
BACKGROUND: Takotsubo cardiomyopathy (TCM) is characterized by reversible left ventricular dysfunction triggered by emotional or physical stress. Only 1%-2% of patients with acute coronary syndrome are diagnosed with TCM. Although obstructive coronary artery disease is frequently considered to be the cause of chest pain, TCM should be considered in some clinical settings. In this case, clinicians did not make a timely and accurate diagnosis for TCM due to a lack of knowledge until the third hospitalization with a left ventriculogram.
CASE SUMMARY: A 55-year-old postmenopausal woman had intermittent chest pain following emotionally stressful events three times in the past 3 years. Cardiac troponin levels increased after each instance of symptom onset. A transthoracic echocardiogram showed reversible left ventricular dysfunction. The patient underwent three coronary angiograms without evidence of coronary artery disease. A left ventriculogram was first performed at the third hospitalization and revealed apical akinesia with ballooning of the apical region and consistent hypercontractile basal segments. The diagnosis of TCM was confirmed. The patient was treated with an angiotensin-converting-enzyme inhibitor (perindopril) and a β-blocker (metoprolol). No complications occurred during the patient's hospitalization. The patient was told to avoid stressful events. During the 9-mo follow-up visit, the patient was asymptomatic with an ejection fraction of 55%.
CONCLUSION: Clinicians should be conscious of the possibility of TCM, especially in postmenopausal women presenting with clinical manifestations similar to acute coronary syndrome without coronary occlusion.
