Cardiogenic shock is a high-acuity, potentially complex, and hemodynamically diverse state of end-organ hypoperfusion that is frequently associated with multisystem organ failure. Despite improving survival in recent years, patient morbidity and mortality remain high, and there are few evidence-based therapeutic interventions known to clearly improve patient outcomes. This scientific statement on cardiogenic shock summarizes the epidemiology, pathophys...

BACKGROUND - This study sought to investigate the optimal percutaneous coronary intervention (PCI) strategy for true unprotected left main coronary artery (ULMCA) bifurcations. METHODS - The FAILS-2 was a retrospective multi-center study including patients with ULMCA disease treated with second-generation drug-eluting stents. Of these, we compared clinical outcomes of a provisional strategy (PS; n=216) ve...

Temporary interruption of dual antiplatelet therapy (DAPT) is not infrequently required in patients undergoing percutaneous coronary intervention (PCI). We sought to describe the procedures and outcomes associated with DAPT interruption in patients treated with DAPT following successful PCI from the Patterns of non-adherence to anti-platelet regimens in stented patients registry (n = 5018). DAPT interruption was prespecified as physician re...

OBJECTIVES - Percutaneous coronary intervention (PCI) of the left main (LM) or proximal left anterior descending artery (pLAD) is considered high-risk as these segments subtend substantial left ventricular myocardial area. We assessed the patterns and associations between dual antiplatelet therapy (DAPT) cessation and 2-year outcomes in LM/pLAD vs. other PCI from the all-comer PARIS registry. METHODS - T...
Clinical Trial | By Shah B, Baber U, Mehran R et al.
BACKGROUND - Elevated white blood cell (WBC) count is associated with increased major adverse cardiovascular events (MACE) in the setting of acute coronary syndrome. The aim of this study was to evaluate whether similar associations persist in an all-comers population of patients undergoing percutaneous coronary intervention in the contemporary era. METHODS AND RESULTS - In the multicenter, prospective, ob...
Characterization of the Average Daily Ischemic and Bleeding Risk After Primary PCI for STEMI
Clinical Trial | By Giustino G, Mehran R, Stone GW et al.
BACKGROUND - The risk of recurrent ischemic and bleeding events after primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) may not be uniform over time, which may affect the benefit-to-risk ratio of guideline-recommended antithrombotic therapies in different intervals. OBJECTIVES - This study sought to characterize the average daily ischemic rates (ADIRs) and a...

Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneousrevascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of ...

OBJECTIVE - The effects of intravascular ultrasound (IVUS)-guided drug-eluting stent (DES) implantation in patients with complex coronary artery lesions remains to be controversial. This study sought to evaluate the outcomes of IVUS guidance in these patients. METHODS- The EMBASE, Medline, and other internet sources ...

It can be argued that severe left main coronary artery (LMCA) disease represents the only anatomic subtype of coronary artery disease for which there is clear and unequivocal prognostic evidence in favor of coronary revascularization across the spectrum of clinical presentation—from stable ischemic heart disease to acute coronary syndrome. For decades, the standard approach to LMCA revascularization has been through coronary artery bypass grafting (CABG...

Contrast-induced nephropathy (CIN) is a serious complication in patients undergoing percutaneous coronary intervention (PCI), and is associated with higher morbidity and mortality. The limiting volume of contrast medium is safest and most reliable strategy for CIN prevention. Intravascular ultrasound (IVUS) serves as an attractive alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of contrast agents. Here, w...
