Year in Review 2024: Noteworthy Literature in Cardiac Anesthesiology
AI summary Read the abstract
This annual review of noteworthy cardiac anesthesiology literature from 2024 covered advances in devices, gene therapy, and transcatheter valve techniques across 447 articles. Among the emerging themes, the review noted the emerging risk of microplastic exposure in cardiovascular events, alongside developments in mechanical circulatory support, anti-inflammatory medications, and implantable wireless devices.
The research findings relevant for Cardiac Anesthesiology studies published in 2024 involved key innovations in devices and gene therapy in addition to the expansion of transcatheter techniques for valve repair or replacement. We reviewed 447 relevant articles and selected 21 as the most noteworthy studies published in 2024. Themes that emerged from our review include the etiology and prevention of delirium or outcomes after mechanical circulatory support. Robust clinical outcome data now supports the use of microaxial flow devices for mechanical circulatory support for cardiogenic shock due to acute myocardial infarction. Pharmacology development presents colchicine as anti-inflammatory medication to prevent atrial fibrillation or intravenous amino acids for kidney protection after cardiopulmonary bypass. Technological advances include implantable wireless pacing-defibrillator devices, pulmonary artery pressure monitoring in heart failure patients, extracorporeal blood purification for preventing acute kidney injury and hypothermic oxygenated perfusion of the donor heart in heart transplantation. Transcatheter interventions on mitral or aortic valve were gaining advances over surgical procedures. Novel paradigms included treatments with gene therapy for cardiac amyloidosis or refractory angina and the emerging risk of microplastic exposure in cardiovascular events.

Micro- and nanoplastic as new modifiable cardiovascular risk factors
AI summary Read the abstract
Tiny plastic particles from everyday pollution, called microplastics and nanoplastics, may be quietly harming your heart, according to this review that pulls together over a decade of research. Scientists found these particles can disrupt cholesterol processing, make blood more likely to clot, and directly damage heart cells, partly by causing inflammation and stress inside cells. While more research is needed to fully understand the risks, this adds plastic pollution to the growing list of factors, alongside diet and exercise, that may affect your cardiovascular health.
Microplastics in the Environment and Human Health: Current State of Knowledge and Future Research Directions
AI summary Read the abstract
Tiny plastic particles called microplastics are now showing up everywhere—not just in oceans and soil, but inside our lungs, gut, blood vessels, and other organs. This review pulls together existing research on how we're exposed to these particles and what they might do to our bodies, highlighting a striking 2024 study that linked microplastics found in artery plaques to a higher risk of heart attacks and strokes. While scientists are still working out the full health impact, the growing evidence suggests it's worth paying attention to and reducing our plastic exposure where we can.
Microplastics and Nanoplastics as a Novel Cardiovascular Risk Factor: A Narrative Review
AI summary Read the abstract
This review summarizes research on tiny plastic particles found in human blood vessels, heart tissue, and blood clots. One study found plaques containing these particles were linked to a higher rate of heart attacks, strokes, and death, and lab studies suggest possible links to inflammation and cell damage.
Microplastics release from coronary catheters: Insights from catheter analysis
AI summary Read the abstract
This study examined whether cardiac catheters used in heart procedures release microplastic particles, and found that all 21 catheter samples tested shed microplastics of varying sizes and types. The findings raise important questions about patient safety, since these tiny plastic fragments could enter the bloodstream during routine cardiovascular procedures.
Microplastics and Nanoplastics in Cardiovascular Disease: An Emerging Cardiovascular Risk Factor
AI summary Read the abstract
Researchers reviewed mounting experimental and early clinical evidence that microplastics and nanoplastics cross epithelial barriers, accumulate in arterial plaques, cardiac tissue, and thrombi, and trigger oxidative stress and coagulation dysregulation, framing these particles as an emerging cardiovascular risk factor that warrants integration into disease prevention frameworks.
