Coronary angiography: a review of the state of the art and the evolution of angiography in cardio therapeutics.

Traditionally, coronary angiography was restricted to visual estimation of contrast-filled lumen in coronary obstructive diseases. Over the previous decades, considerable development has been made in quantitatively analyzing coronary angiography, significantly improving its accuracy and reproducibility.  Notably, the integration of artificial intelligence (AI) and machine learning into quantitative coronary angiography (QCA) holds promise for further enhancing diagnostic accuracy and predictive capabilities.

Global use of angiotensin receptor neprilysin inhibitor in heart failure and reduced, below normal and supranormal ejection fraction.

Background: The global use of angiotensin receptor neprilysin inhibitor (ARNI) in clinical practice, especially in patients with heart failure and below-normal ejection fraction (HFbnEF), has not been thoroughly evaluated. We aimed to investigate the characteristics, outcomes, and adverse events in patients treated with ARNI for HF with reduced (HFrEF), below-normal (HFbnEF), and supranormal left ventricular EF (HFsnEF).

Methods: This observational study analyzed data from the electronic healthcare records (EHR) of patients with HF treated with ARNI between 2015 and 2022 in North and South America, Europe, the Middle East, Africa, and Asia-Pacific.

Association Between Late Gadolinium Enhancement with or Without Reverse Remodeling and Prognosis.

Late gadolinium enhancement (LGE) in cardiovascular magnetic resonance imaging (CMR) prevents left ventricular reverse remodeling (LVRR), resulting in a poor prognosis. However, the prognosis of patients who have LGE and achieve LVRR and patients who do not have LGE and do not achieve LVRR remains unknown. This study aimed to answer this question by sorting patients with heart failure based on the presence of LGE and LVRR and comparing their prognoses.

Sodium-Glucose Cotransporter-2 Inhibitors in Heart Failure with Malnutrition, Frailty, Sarcopenia, or Cachexia.

(1) : In patients with heart failure (HF) and impaired nutritional status or decreased muscle mass, sodium-glucose cotransporter-2 inhibitors (SGLT2is) may worsen these conditions and result in poor prognosis, especially worsening of frailty. We aimed to investigate the relationship between SGLT2is and clinical outcomes, including frailty-related events, in patients with HF and malnutrition, frailty, sarcopenia, or cachexia. (2) : In this retrospective observational cohort study, a global federated health research network provided data on patients with HF and malnutrition, frailty, sarcopenia, or cachexia from January 2016 to December 2021.

Evaluation of Collateral Source Characteristics With 3-Dimensional Analysis Using Micro-X-Ray Computed Tomography.

Background: Collateral arteries provide an alternative blood supply and protect tissues from ischemic damage in patients with peripheral artery disease. However, the mechanism of collateral artery development is difficult to validate.

Methods And Results: Collateral arteries were visualized using micro-x-ray computed tomography.
