Our objective was to evaluate the clinical effectiveness of the SYNERGY stent (Boston Scientific Corporation, Marlborough, Massachusetts) in patients with ST-elevation myocardial infarction (STEMI). The only drug-eluting stent approved for treatment of STEMI by the Food and Drug Administration is the Taxus stent (Boston Scientific) which is no longer commercially available, so further data are needed. The CLEAR (Colchicine and spironolactone in patients with myocardial infarction) SYNERGY stent registry was embedded into a larger randomized trial of patients with STEMI (n = 7,000), comparing colchicine versus placebo and spironolactone versus placebo.

Methods: Retrospective, multicenter registry in patients undergoing optical coherence tomography (OCT) guided intervention with OPN NC.

Background: Catheter-induced coronary artery dissection (CICAD) is a rare complication of coronary angiography. The association between access site and CICAD remains unclear; however, transradial access (TRA) may be associated with a higher incidence of CICAD due to access vessel tortuosity and the mechanical disadvantage of catheters designed for the transfemoral access (TFA) approach.
Methods: In this retrospective study, the reports of consecutive left heart catheterizations between April 2007, and December 2021 were reviewed for CICAD.
Background: Cardiogenic shock (CS) complicates 5%-10% of acute myocardial infarction (AMI) and is the leading cause of early mortality. It remains unclear whether percutaneous mechanical support (pMCS) devices improve post-AMI CS outcome.
Methods: A systematic review of original studies comparing the effect of pMCS on AMI-CS mortality was conducted with the use of Medline, Embase, Google Scholar, and the Cochrane Library databases.
Objectives: To investigate the clinical profiles and outcomes of young adults presenting with ST-segment elevation myocardial infarction (STEMI).
Methods: We retrospectively reviewed King Saud Medical City, Riyadh, Saudi Arabia, registry between January 2016 and November 2017 for all patients younger than 45 years old who were admitted with STEMI. We compared this study population to a control group of patients aged 45 years and older who were enrolled in the same period.
The coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), represents the pandemic of the century, with approximately 3.5 million cases and 250,000 deaths worldwide as of May 2020. Although respiratory symptoms usually dominate the clinical presentation, COVID-19 is now known to also have potentially serious cardiovascular consequences, including myocardial injury, myocarditis, acute coronary syndromes, pulmonary embolism, stroke, arrhythmias, heart failure, and cardiogenic shock.

Methods: We conducted a prospective, non-randomized, multi-center, observational all-comers registry of patients undergoing percutaneous coronary intervention (PCI) with Orsiro SES at two high-volume Canadian centers. The primary endpoint was one-year target lesion failure (TLF) defined as a composite of cardiac death, target-vessel myocardial infarction (MI), coronary artery bypass grafting and clinically driven target lesion revascularization.
