The accurate non-invasive detection and estimation of central aortic pressure waveforms (CAPW) are crucial for reliable treatments of cardiovascular system diseases. But the accuracy and practicality of current estimation methods need to be improved. Our study combines a meta-learning neural network and a physics-driven method to accurately estimate CAPW based on personalized physiological indicators.

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.

Sepsis-induced cardiomyopathy (SICM) is a life-threatening complication of sepsis characterized by myocardial dysfunction. SICM significantly increases mortality rates in sepsis. Despite its clinical relevance, SICM lacks a unified definition and standardized diagnostic criteria, complicating early identification and treatment.

GECs are used for stent delivery into the coronary arteries of patients with difficult anatomy due to tortuosity, calcification, or chronic total occlusion (CTO) vessels. Stent and balloon placement has become challenging in patients with increasing lesion complexity due to tortuosity, vessel morphology, length of the lesion, and respiratory movements.

However, the relationship between NO bioavailability, dynamic regulation of protein -nitrosylation by trans- and de-nitrosylases, and HFpEF pathophysiology has not been elucidated. Here, we provide novel insights into the delicate interplay between NO bioavailability and protein -nitrosylation in HFpEF.
