A 69-year-old woman and a 29-year-old man were admitted to our hospital after successful resuscitation of out-of hospital cardiac arrest. In the first case, electrocardiogram showed mild ST-segment elevation in leads V3-V5. Coronary angiography did not show any obstructive coronary artery disease, and left ventriculography showed apical ballooning of the left ventricular chamber. She was diagnosed as having the classic form of tako-tsubo cardiomyopathy. In the second case, electrocardiogram did not show ST-segment elevation in any lead. Coronary angiography showed no coronary artery disease and left ventriculography showed basal ballooning of the left ventricular chamber. He was diagnosed as having the variant form of tako-tsubo cardiomyopathy. In both cases, left ventricular function returned to normal, but they died of multiple organ failure. In conclusion, cardiologists should recognize that takotsubo cardiomyopathy can occur even after successful resuscitation of cardiac arrest. Early diagnosis and appropriate intensive care are essential in these critically ill patients.

Background: There is scarce data on the prognostic value of frailty in patients with Takotsubo cardiomyopathy (TCM). This study aimed to assess the association between frailty and in-hospital outcomes in patients with TCM.
Methods: Adult admissions with TCM were included using the 2016-2019 National Inpatient Sample database.

Background: Levosimendan (LEVO), a calcium sensitizer and adenosine triphosphate-dependent potassium channel opener, has been widely used for decades in medical and surgical patients for advanced heart failure (HF), right ventricular failure, cardiogenic shock, takotsubo cardiomyopathy, pulmonary hypertension, and so on. Currently, as the limited scope and lack of comprehensive data in current LEVO publications, there is an increasing obstacle to conducting new studies that require integrated information and quantifiable results. Thus, the current study was performed to identify the research trends and hot spots in LEVO-related publications using bibliometric software.

We present a case of a 73-year-old woman with a medical history significant for hyperlipidemia, on pravastatin, who developed Takotsubo cardiomyopathy following a diagnosis of osteoporosis. She presented to the Emergency Department with acute transient left arm pain that resolved spontaneously. Investigations revealed elevated troponin levels, non-specific electrocardiographic changes, no significant coronary artery disease on angiography, and left ventricular systolic dysfunction, findings consistent with Takotsubo cardiomyopathy.

We present a case of a 52-year-old male with no known past medical history who presented to an outside hospital with acute chest pain. Initial workup revealed anteroseptal ST-elevation myocardial infarction (STEMI) for which the patient was transferred to our facility for emergent percutaneous coronary intervention (PCI). However, the patient's hospital course revealed numerous confounding pathologies that can also present as STEMI, including transthoracic echocardiogram (TTE) abnormalities consistent with takotsubo cardiomyopathy (TCM) as well as myocardial bridging presenting as post-PCI STEMI in the setting of nitroglycerin use.
