Background: A need exists for systematic evaluation of the differences in baseline characteristics and early outcomes between patients enrolled in randomized controlled trials (RCTs) and clinical practice for coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI).
Methods: Systematic searches were conducted to identify RCTs comparing CABG vs PCI and CABG or PCI registries. Sixteen predefined baseline characteristics and 30-day mortality were extracted from the included studies. Pooled proportion and mean with 95% CI were calculated for binary and continuous outcomes, respectively, by using the random effects model.
Results: Fourteen RCTs and 10 registries including more than 2 million patients were included. Registry patients who underwent CABG had a higher prevalence of hypertension, smoking, reduced left ventricular ejection fraction, and prior myocardial infarction, but a lower prevalence of single-vessel disease when compared with CABG-treated patients included in RCTs. Regarding PCI, hypertension, hyperlipidemia, left main coronary artery disease, triple-vessel coronary disease, and NYHA functional class
Conclusions: There were significant differences in baseline characteristics and 30-day mortality between patients enrolled in RCTs comparing CABG vs PCI and CABG and PCI registries. However, results were mixed, and the discrepancy was less than seen in other fields.

Triglyceride to high density lipoprotein cholesterol ratio and major adverse cardiovascular events in ACS patients undergoing PCI.
Sci Rep
December 2024
State Key Laboratory of Frigid Zone Cardiovascular Disease, Cardiovascular Research Institute, Department of Cardiology, General Hospital of Northern Theater Command, Shenyang, 110016, China.
The triglyceride to high density lipoprotein cholesterol (TG/HDL-C) ratio has been consistently linked with the risk of coronary heart disease (CHD). Nevertheless, there is a paucity of studies focusing on acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) or experiencing bleeding events. The study encompassed 17,643 ACS participants who underwent PCI.

Aims: This study compared echocardiography (echo) and cardiac computed tomography (CT) in measuring the Wilkins score and evaluated the potential added benefit of CT in predicting immediate percutaneous mitral valvuloplasty (PMV) outcomes in rheumatic mitral stenosis (MS) patients deemed eligible for PMV by echo.
Methods And Results: From a multicentre registry of 3,140 patients with at least moderate MS, we included 96 patients (age 56.4±11.

Background: This is a case report of a patient with Fabry disease (FD). We successfully treated a patient with ventricular septal hypertrophy and left ventricular outflow tract (LVOT) obstruction caused by FD. We report our exclusive new surgery for patients with LVOT obstruction, percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) procedure™ (percutaneous intramyocardial septal radiofrequency ablation).

In-stent restenosis represents a major cause of failure of percutaneous coronary intervention with drug-eluting stent implantation. Computational multiscale models have recently emerged as powerful tools for investigating the mechanobiological mechanisms underlying vascular adaptation processes during in-stent restenosis. However, to date, the interplay between intervention-induced inflammation, drug delivery and drug retention has been under-investigated.
