Article Synopsis
- Guidelines for cardiac arrest management were analyzed to assess the strength and quality of the evidence supporting them, revealing both strengths and significant gaps in knowledge.
- The review of the 2020 American Heart Association (AHA) Guidelines identified 254 recommendations, mostly classified under advanced life support (ALS) and basic life support (BLS), but only 1% of recommendations were based on the strongest level of evidence (LOE A).
- Only 32% of the highest class recommendations were backed by strong evidence (LOE A or B), highlighting the need for more rigorous research, especially randomized trials, to improve the quality of guidelines.
Background And Aims: The long-term outcomes of percutaneous coronary intervention (PCI) vs. coronary artery bypass grafting (CABG) in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and multivessel disease remain debated.
Methods: The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registry was used to analyse 57 097 revascularized patients with NSTEMI with multivessel disease in Sweden from January 2005 to June 2022.
Background: Transcatheter aortic valve implantation (TAVI) is expanding to younger patients, and the management of valve failure is a growing clinical problem. The transcatheter heart valve (THV) of choice for redo-TAVI is a complex decision, and first reports have examined the use of the Sapien 3™ THV (Edwards Lifesciences; Irvine, CA, USA) in failed Evolut™ (Medtronic, Minneapolis, MN, USA) THV. However, several different technical approaches may be worth consideration, and the subject remains a matter of debate.

Both diagnostic methods require the placement of a pressure wire in the coronary artery during invasive coronary angiography. Quantitative flow ratio (QFR) is an angiography-based computational method for the estimation of FFR that does not require the use of pressure wires.

- * A study analyzed 15,856 ECGs from emergency patients in Sweden and trained a convolutional neural network (ResNet) to predict troponin elevation, achieving an accuracy of 71.43% and a high negative predictive value of 0.8660.
- * The model's promising performance suggests that similar neural networks could be used in emergency settings for rapid triage of patients suspected of having heart issues.
