Fractional flow reserve (FFR) has proven to be superior to angiography as a guide to revascularization due to a significant reduction in the number of both long-term and short-term events. Furthermore, deferring treatment of lesions without evidence of ischemia offers an excellent prognosis. Many studies including mostly stable patients showed a significant degree (as high…
VALIDATE-SWEDEHEART: bivalirudin seems to be losing ground
Another important work that does not see the benefits of bivalirudin over heparin as monotherapy as regards both efficacy (death and MI) and safety end points (bleeding) in patients undergoing acute myocardial infarction with and without ST elevation. The study VALIDATE-SWEDEHEART, presented at ESC, simultaneously published in the New England Journal of Medicine, randomized 6000 patients…
Early Invasive Strategy Benefits High-Risk Patients
Early angiography is not associated with a reduction in mortality compared with a more delayed invasive strategy in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). However, a new meta-analysis published by The Lancet supports the idea that certain high-risk patients would benefit from it. Patients with elevated cardiac biomarkers, a high GRACE score, diabetes, or advanced…
The transradial approach reduces the risk of kidney injury in acute patients
It remains unclear whether transradial access, compared with transfemoral access, presents a different risk of post-procedural kidney injury for patients admitted with acute coronary syndrome. Historically, it has been considered (without any evidence) that, given the higher difficulty associated with transradial access, it would require longer fluoroscopy time and higher contrast volume, which would eventually…
Leaders Free ACS: Good Results for the Polymer-Free Stent at 2 Years in ACS
Courtesy of the SBHCI. Guidelines recommend dual antiplatelet therapy for a year in patients admitted with coronary acute syndrome. However, patients at high risk for bleeding who receive coronary angioplasty have been historically excluded from studies. The new polymer-free stent BioFreedom allows for the reduction of dual antiplatelet therapy time, due to rapid drug elution…
Follow-up at 10 years for invasive vs. conservative strategy for non-ST-segment elevation infarction
The ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes) trial compared early invasive strategy with a selective invasive strategy in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS), with elevated markers such as cardiac troponin T. The absence of long-term benefit of an early invasive strategy at 1 and 5 years had already been reported.…
FFR-Guided ACS Revascularization Apparently Superior to Culprit Vessel Treatment
Using fractional flow reserve (FFR) to guide revascularization of all functionally significant lesions in the setting of acute coronary syndrome appears to improve outcomes over treating only the culprit artery, according to the Compare-Acute trial. This study, conducted at 24 centers in Europe and Asia, enrolled 885 patients who were stable following successful primary angioplasty and…
Post NSTEMI Invasive Strategy Timing
The aim of this meta-analysis, which included all randomized studies carried out to date, was to compare an early invasive strategy vs. a delayed invasive strategy in patients undergoing non ST elevation myocardial infarction (NSTEMI). Even though there is no doubt invasive strategies reduce events rate such as death and re-infarction in NSTEMI patients,…
Contemporary Ventricular Assist Devices: Hemodynamic Consequences
Courtesy of Dr. Agustín Vecchia. Despite current technological advancements and improvement in reperfusion rates in a setting of infarction, cardiogenic shock still is a relatively frequent complication with a mortality rate close to 50%. The need to augment cardiac output in these patients and the fact that the popular intraaortic balloon counterpulsation has not been able to…
Cardiovascular Events Reduction: Bivalirudin or Heparin?
The MATRIX study did not find a clear advantage of bivalirudin over unfractioned heparin to reduce major adverse cardiovascular events (MACE) or net cardiovascular adverse events (NCAE) in patients undergoing acute coronary syndrome receiving PCI. This new analyzis confirms there is no difference in ischemic and thrombotic events in patients with acute coronary syndrome…
