Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a clinical entity characterized by the absence of significant coronary artery obstruction in epicardial arteries (<50%) on coronary angiography in the setting of acute myocardial infarction (AMI). This article aims to provide a narrative review of the pathophysiological mechanisms, diagnostic challenges, and prognosis associated with MINOCA based on pathophysiology regarding the atherosclerotic and non-atherosclerotic causes. Etiological factors, including thromboembolism, coronary artery spasm, spontaneous coronary artery dissection, coronary microvascular disease, and supply-demand mismatch, are addressed.

- Heart failure (HF) is a serious health issue that has high rates of illness and death, with electrical conduction problems being a key factor in its progression.
- Conduction system pacing (CSP) is a new treatment method that includes techniques like His bundle pacing and left bundle branch area pacing, recommended for certain patients despite mainly being supported by observational studies.
- There are significant challenges in implementing CSP, such as difficulties with lead implantation and the need for better tools, making future large-scale randomized controlled trials necessary for improving treatment strategies for HF patients.
Article Synopsis
- The study examined the effectiveness of PSMA PET/CT imaging in tracking patients with metastatic castration-resistant prostate cancer (mCRPC) undergoing Radium-223 treatment, as traditional methods like PSA values are not reliable for follow-up.
- A total of 28 patients were analyzed, finding that a significant portion showed disease progression using two different imaging criteria, with patients experiencing progression having a higher risk of death compared to those without progression.
- The findings suggest that PSMA PET/CT is a useful tool for monitoring treatment response in mCRPC patients, with both imaging criteria yielding similar predictive outcomes for overall survival after treatment.
An older woman developed dyspnea after instrumented lumbar spinal fusion surgery. During clinical work-up, a chest radiography revealed a U-shaped object within the cardiac silhouette. Further imaging confirmed that the object was entrapped in the tricuspid subvalvular apparatus.
