The aim of this case report is to show the capability of cardiac computed tomography (CT) in combination with dual-energy CT (DECT) delayed myocardial enhancement to support diagnostic decision making in the complicated differential diagnosis of true versus false left ventricle (LV) aneurysm, as well as provide additional information that can influence overall patient outcome. We present a 71-year-old obese patient with metabolic syndrome, stable chronic coronary syndrome with three-vessel disease, and recent chest discomfort. His coronary angiogram showed no significant coronary artery stenosis, but suspicion of LV apical pseudoaneurysm was expressed. Neither transthoracic nor transesophageal echocardiography was able to dismiss this suspicion. Consequently, coronary CT angiography (CCTA) followed by DECT delayed myocardial enhancement was performed. Findings on CCTA and DECT confirmed the diagnosis of a true aneurysm. Moreover, fibrotic changes within the hypertrophic myocardium were visualized. This finding will influence further patient therapy as well as the outcome. DECT delayed myocardial enhancement can be an important complementary tool for distinguishing true versus false LV aneurysms. Moreover, it can provide additional information for making complex diagnose. Adding DECT delayed myocardial enhancement to CCTA can replace cardiac magnetic resonance imaging evaluation in certain settings.

Unlabelled: Testing methods of detecting various cardiac biomarkers play a significant influence in determining and treating cardiac-related conditions and ultimate prognosis. With the increasing global prevalence of cardiac disease, the importance of rapid testing methods in diagnosis and management has grown tremendously. The point-of-care testing (POCT) method is a potential biochemical diagnostic technique that may overcome the issue of delayed laboratory results, particularly in regions with limited access to advanced laboratory equipment or resource-constrained.

Our case report characterizes a rare presentation of mid-ventricular Takotsubo cardiomyopathy (TTC) in a patient with suspected myocarditis as an underlying cause. Mid-ventricular TTC is a rare variant of TTC presenting with overlapping symptoms and physical exam findings of acute coronary syndrome, which often leads to misdiagnosis as myocardial infarction. Our case is of a 77-year-old female patient with a history of hyperlipidemia, right breast ductal carcinoma in situ, and diverticular disease who presented to the emergency department for evaluation of chest pain radiating to the jaw with associated nausea and vomiting.

Methods: We recruited adults with AMI, who underwent Level-III SA testing during hospitalization. Delayed-enhancement cardiac magnetic resonance (CMR) imaging was performed to quantify AMI size (percent-infarcted myocardium).

Background: Acute carbon monoxide poisoning (COP) has been a common cause of emergency hospital visits over the past decade. Besides the immediate symptoms of poisoning, carbon monoxide exposure can cause various long-term complications, especially delayed neurological sequelae (DNS) and myocardial injury (MI).
Methods: This study retrospectively enrolled 502 patients with COP, including complete collection data, from the Taiwan National Poison Control Center between January 1, 2000, and December 31, 2015.
