Bleeding after percutaneous coronary intervention (PCI) is more common in women than in men. However, the relationship of sex and bleeding with outcomes is less well studied.

Risk of acute kidney injury after percutaneous coronary interventions using radial versus femoral vascular access: insights from the Blue Cross Blue Shield of Michigan Cardiovascular Consortium.
Circ Cardiovasc Interv
PUBLISHED: 02-25-2014
Show Abstract
Hide Abstract
Transradial percutaneous coronary intervention (PCI [TRI]) does not involve catheter manipulation in the descending aorta, whereas transfemoral PCI (TFI) does. Therefore, the risk of acute kidney injury (AKI) after PCI might be influenced by vascular access site. We compared risks of AKI and nephropathy requiring dialysis (NRD) among patients treated with TRI and TFI.

Implantable cardioverter-defibrillators (ICDs) treat ventricular tachycardia or fibrillation but may also deliver unnecessary shocks. We sought to determine if the frequency of ICD-detected non-sustained or diverted (NSD) episodes increases before appropriate or inappropriate ICD shocks.

Preprocedural statin use in patients undergoing percutaneous coronary intervention.
Am. Heart J.
PUBLISHED: 01-14-2014
Show Abstract
Hide Abstract
Earlier studies suggest that administering statins prior to percutaneous coronary interventions (PCIs) is associated with lower risk of periprocedural myocardial infarction and contrast-induced nephropathy. Current American College of Cardiology/American Heart Association guidelines recommend routine use of statins prior to PCI. It is unclear how commonly this recommendation is followed in clinical practice and what its effect on outcomes is.

Adjudication of thousands of implantable cardioverter defibrillator (ICD)-treated arrhythmia episodes is labor intensive and, as a result, is most often left undone.

Daylight savings time and myocardial infarction.
Open Heart

Show Abstract
Hide Abstract
Prior research has shown a transient increase in the incidence of acute myocardial infarction (AMI) after daylight savings time (DST) in the spring as well as a decrease in AMI after returning to standard time in the fall. These findings have not been verified in a broader population and if extant, may have significant public health and policy implications.

A random forest based risk model for reliable and accurate prediction of receipt of transfusion in patients undergoing percutaneous coronary intervention.

Hide Abstract
Transfusion is a common complication of Percutaneous Coronary Intervention (PCI) and is associated with adverse short and long term outcomes. There is no risk model for identifying patients most likely to receive transfusion after PCI. The objective of our study was to develop and validate a tool for predicting receipt of blood transfusion in patients undergoing contemporary PCI.

The association between contrast dose and renal complications post PCI across the continuum of procedural estimated risk.
PLoS ONE
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
Prior studies have proposed to restrict the contrast volume (CV) to <3x calculated creatinine clearance (CCC), to prevent contrast induced nephropathy (CIN) post percutaneous coronary interventions (PCI). The predictive value of this algorithm for CIN and therefore the benefit of this approach in high risk patients has been questioned. The aim of our study was to assess the association between contrast dose and the occurrence of CIN in patients at varying predicted risks of CIN and baseline CCC following contemporary PCI.

Hide Abstract
Outcome data regarding postoperative acute coronary syndrome treated with percutaneous coronary intervention (PCI) are limited. The objective of this study was to determine clinical outcomes of patients undergoing PCI within 7 days after a surgical procedure. We assessed outcomes of 517 patients who underwent PCI within 7 days after a surgery across 44 hospitals from January 2010 to December 2011 from the Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry. Patients with postoperative PCI were compared with all other patients with PCI using propensity-matched analysis. Of the 65,175 patients who underwent PCI within the study period, 517 patients had undergone surgery within the previous 7 days. In unadjusted analysis, patients with postsurgical PCI had higher in-hospital mortality (6.96% vs 1.33%), stroke (0.96% vs 0.26%), bleeding events (6.96% vs 2.6%), heart failure (6.96% vs 2.36%), and cardiogenic shock (7.16% vs 1.95%). After propensity matching, mortality remained higher in postsurgical patients (6.5% vs 3.96%, odds ratio 1.7 [1.1 to 2.6], p = 0.02). The odds of mortality were especially high among patients who would otherwise be considered low risk (<1% of predicted mortality in a nonsurgical setting) in whom a recent surgery was strongly associated with death (odds ratio 5.7, p = 0.02). In conclusion, PCI performed within 7 days after a surgical procedure is associated with an increased risk of early mortality. Although some of this increased risk is related to an adverse clinical profile, higher mortality is also observed in patients otherwise considered low risk for PCI.

The effect of left ventricular electrical delay on AV optimization for cardiac resynchronization therapy.

Show Abstract
Hide Abstract
The role of atrioventricular optimization (AVO) for cardiac resynchronization therapy (CRT) is controversial. Identifying subgroups that benefit from optimization is important to improve CRT outcomes. Pacing at sites of late electrical activation, as assessed by the QLV interval, improves remodeling with CRT.

Several clinical trials have confirmed that cardiac resynchronization therapy (CRT) improves outcomes in well defined patient populations. It is uncertain, however, whether outcomes are similar in real-world clinical settings. This study compared outcomes after CRT with defibrillator (CRT-D) in a large real-world private-practice cardiology setting with those in the COMPANION multicenter trial.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
