Fewer than half (48%) of patients receiving a heart stent, or percutaneous coronary intervention (PCI), had the provided stent card with them when surveyed at a later date, according to researchers at Atlantic Health System’s Morristown Medical Center. Even when they had their stent cards, most patients were unable to identify the type of stent they had, which blood vessel it was in, or the date of the previous procedure. Eighty-eight percent of patients did have their smartphone, however. The study will be presented as a moderated poster the morning of May 15, during the American College of Cardiology 70th Annual Scientific Session (ACC.21).
A new research paper funded in part by the National Heart, Lung and Blood Institute (NHLBI) shows a clear advantage of genetic testing in helping health care providers choose the appropriate anti-platelet drug. Testing helps determine if a patient carries genetic variants in CYP2C19 that cause loss of its function. These variants interfere with the body’s ability to metabolize and activate clopidogrel, an anti-platelet medication.
The OPTIMIZE randomized trial comparing a novel, low-profile drug-eluting stent (DES) facilitating transradial access (TR) and direct stenting (DS) to existing DES did not establish non-inferiority of the new stent based on the prespecified study statistical analysis plan, likely due to the definition of periprocedural target vessel myocardial infarction (TVMI) coupled with a large proportion of high-sensitive cardiac troponin assays used in the trial.
A large subgroup analysis of a randomized clinical trial showed neither a mortality risk nor benefit associated with the use of paclitaxel drug-coated devices (DCD) in the treatment of peripheral artery disease (PAD). The study also found that the benefit of rivaroxaban use on reducing ischemic limb and cardiovascular outcomes was consistent regardless of whether a DCD was used.
For patients undergoing percutaneous coronary intervention (PCI) that also require oral anticoagulation, treatment with a nanotechnology polymer-coated stent plus 14-day dual anti-platelet therapy (DAPT) did not reduce bleeding or establish non-inferior outcomes for thrombotic events compared with a drug-eluting stent (DES) and standard three or six-month DAPT therapy.
Results from the randomized controlled TARGET FFR trial show that while a physiology-guided percutaneous coronary intervention (PCI) optimization strategy did not achieve a significant increase in the proportion of patients with final FFR ≥0.90, it reduced the proportion of patients with a residual FFR ≤0.80 following PCI.
An individual patient data pooled analysis comparing the use of bivalirudin versus heparin in heart attack patients undergoing percutaneous coronary intervention (PCI) found that bivalirudin use was associated with similar overall rates of 30-day mortality across all heart attack patients, but lower rates of serious bleeding events. Moreover, mortality was reduced in patients with ST-segment elevation myocardial infarction (STEMI) who were treated with a post-PCI bivalirudin infusion.
The TCT Connect agenda is now available online. TCT, the annual scientific symposium of CRF and the world’s premier educational meeting specializing in interventional cardiovascular medicine, will take place online October 14-18. Every year, TCT features major medical research breakthroughs and gathers leading researchers and clinicians from around the globe to present and discuss the latest evidence-based research in the field.
Rutgers engineers have created a highly effective way to paint complex 3D-printed objects, such as lightweight frames for aircraft and biomedical stents, that could save manufacturers time and money and provide new opportunities to create “smart skins” for printed parts. The findings are published in the journal ACS Applied Materials & Interfaces.
Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.
New data from the randomized, placebo-controlled TWILIGHT trial found that compared to ticagrelor plus aspirin, ticagrelor monotherapy reduces bleeding events without increasing the risk of death, myocardial infarction, or stroke in high-risk patients who have undergone successful percutaneous coronary intervention (PCI) and completed three months of dual antiplatelet therapy (DAPT).
