Usefulness of a Left Ventriculogram in Patients Presenting With Acute Coronary Syndrome Due to Takotsubo Cardiomyopathy: A Case Series.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionTakotsubo cardiomyopathy (TCM) is an acute and reversible cardiac condition in response to stress, characterised by apical ballooning of the left ventricle (LV) in the absence of coronary artery obstruction. Although the exact pathophysiology remains unclear, it is believed to be triggered by an endogenous surge of catecholamines in response to physiological or emotional stress. TCM patients generally experience a good recovery, and LV function typically recovers within two to three months in most patients. METHODOLOGY: We present a case series of six patients who presented with chest pains and electrocardiographic (ECG) changes consistent with acute myocardial infarction (AMI). The selection criteria were patients presenting with chest pain, raised troponin I, and ECG changes suggestive of acute coronary syndrome (ACS).
resultsThese patients ranged in age from their mid-50s to their mid-80s. All these patients presented with chest pain triggered by various activities, including watching a scary movie, adrenaline injection for anaphylaxis following consumption of pistachios, and the patient arguing with neighbours. All these patients underwent coronary angiograms that did not reveal any obvious culprit obstructive lesions, and a left ventriculogram (LVG) was performed in all six patients, demonstrating features of TCM. Most patients had cardiac magnetic resonance imaging (CMRI) as an outpatient, confirming the diagnosis of TCM. LVG showed classical apical ballooning in most patients presenting with TCM.
conclusionLVG can help diagnose TCM in patients with poor acoustic windows. This can be easily performed during coronary angioplasty in patients presenting with chest pain and suspected ACS.
