Over most of the history of interventional cardiology, it has been tacitly assumed that once flow-limiting coronary disease had been documented, angiography was sufficient to plan percutaneous coronary intervention (PCI) and, subsequently, to decide if an optimal procedural result had been achieved. This view has been challenged by recent studies evaluating the results of PCI with fractional flow reserve and nonhyperemic pressure ratios. Evidence has accumulated showing that suboptimal functional PCI results occur frequently despite a good angiographic result and that they are associated with worse patient outcomes. In this article, we discuss how available coronary physiology tools, either guide wire or image-based, may address this problem by facilitating better procedural planning and PCI precision and optimization.

A Meta-Analysis on the Efficacy of Noninvasive Positive Pressure Ventilation Combined With Pressure Support Ventilation in Treating Chronic Heart Failure.
Clin Cardiol
January 2025
General Practice, Chengde Central Hospital, Chengde, China.
Objective: To evaluate the clinical efficacy and safety of noninvasive positive pressure ventilation combined with pressure support ventilation (NPPV-PSV) in the treatment of chronic heart failure (CHF) through a meta-analysis.
Methods: A systematic search was conducted using PubMed, Embase, Web of Science, Cochrane Library, CNKI and Wanfang databases to find randomized controlled trials and cohort studies on NPPV-PSV treatment for CHF. The period of search was set from inception until 2024.
Correlating autonomic physiology with symptoms of autonomic dysreflexia after spinal cord injury.

Department of Physical Medicine and Rehabilitation, Mayo Clinic, Rochester, Minnesota, USA.
Background: Individuals with spinal cord injury (SCI) commonly have autonomic dysreflexia (AD) with increased sympathetic activity. After SCI, individuals have decreased baroreflex sensitivity and increased vascular responsiveness.
Objective: To evaluate the relationship between baroreflex and blood vessel sensitivity with AD symptoms.
Inhibition of aortic CX3CR1+ macrophages mitigates thoracic aortic aneurysm progression in Marfan syndrome in mice.

The pathogenesis of thoracic aortic aneurysm (TAA) in Marfan syndrome (MFS) is generally attributed to vascular smooth muscle cell (VSMC) pathologies. However, the role of immune cell-mediated inflammation remains elusive. Single-cell RNA sequencing identified a subset of CX3CR1+ macrophages mainly located in the intima in the aortic roots and ascending aortas of Fbn1C1041G/+ mice, further validated in MFS patients.

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide, with inflammation playing a pivotal role in its pathogenesis. T lymphocytes are crucial components of the adaptive immune system that have emerged as key mediators in both cardiac health and the development and progression of CVD. This Review explores the diverse roles of T cell subsets, including Th1, Th17, γδ T cells, and Tregs, in myocardial inflammatory processes such as autoimmune myocarditis and myocardial infarction.

Modulating immune function is a critical strategy in cancer and atherosclerosis treatments. For cancer, boosting or maintaining the immune system is crucial to prevent tumor growth. However, in vascular disease, mitigating immune responses can decrease inflammation and slow atherosclerosis progression.
