Acute myocardial infarction (AMI) represents a critical health challenge characterized by a significant reduction in blood flow to the heart, leading to high rates of mortality and morbidity. Cardiac troponins, specifically cardiac troponin I and cardiac troponin T, are essential proteins involved in cardiac muscle contraction and serve as vital biomarkers for the diagnosis of AMI. Aptasensors utilize synthetic aptamers or peptides with high affinity for specific biomarkers and offer a promising approach for integration into portable, user-friendly point-of-care (POC) applications. This review explores recent advances in POC aptasensor-based platforms for the rapid detection of cardiac troponin biomarkers. Furthermore, this review addresses current challenges and potential future directions in the development of aptasensor. Also, it highlights their potential to improve timely and accurate diagnosis in clinical and emergency settings.

Background & Aim: The definition and clinical relevance of percutaneous coronary intervention (PCI)-related myocardial infarction (MI) has been a topic of significant debate and controversy. It has particularly garnered widespread attention recently due to a contemporary trend of including it as a component of primary end points in major trials. The study aimed to assess the clinical relevance of PCI-related MI (PMI) according to the Fourth Universal Definition of MI using a high-sensitivity troponin (hs-Tn) assay in a real-world setting.

Aim: The diagnostic criteria for type 2 myocardial infarction identify a heterogenous group of patients with variable outcomes and no clear treatment implications. We aimed to determine the implications of a new clinical classification for myocardial infarction with more objective diagnostic criteria using cardiac imaging.
Methods: In a prospective cohort study, patients with type 2 myocardial infarction underwent coronary angiography and cardiac magnetic resonance imaging or echocardiography.

Although relatively rare, cardiac metastases represent a significant clinical challenge because of their impact on cardiac function and overall patient prognosis. This case presents a rare and atypical presentation of a patient with ventricular arrhythmia revealing a metastatic cancer in the heart. A 59-year-old man with lung cancer was admitted for chest tightness and episodes of syncope.

A 60-year-old man with squamous cell carcinoma of the tongue had atypical chest pain and mild troponin elevation. No significant electrocardiogram changes or arrhythmias were noted. Cardiac magnetic resonance revealed several myocardial metastases with pericardial involvement, confirmed by positron emission tomography/computed tomography.

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.
