After coronary angioplasty, the use of drugs whose efficacy for the reduction of major events has been proven declines over time, which is associated with worse patient prognosis. Sometimes, without meaning to, we convey to patients the idea that, once the stent has been implanted, the artery is “cured” or that the only potential future…
Pre-TAVR Revascularization: Angiographic or Physiological?
In patients undergoing transcatheter aortic valve replacement (TAVR), fractional flow reserve (FFR) guided revascularization is associated with favorable results compared against the traditional angiography guided revascularization. Given the complete lack of randomized studies, this observational study is the best we have to decide how to guide revascularization in patients with symptomatic severe aortic stenosis undergoing…
AHA 2019 | ISCHEMIA-CKD: Chronic Kidney Disease and Stable Coronary Disease
Among patients in the main ISCHEMIA trial, those with chronic kidney disease are a particularly high-risk subgroup. However, an invasive strategy with coronary angiography and revascularization did not improve the rate of events, similarly to what happened in the general population for the aforementioned trial. The rate of death or acute myocardial infarction was 36.4%…
AHA 2019 | ISCHEMIA: The Invasive Approach (PCI or Surgery) Results Similar to Optimal Medical Treatment
After a several year follow up, the International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) has shown that an invasive approach in addition to optimal medical treatment (OMT) does not offer benefits when it comes to preventing major cardiovascular events compared against optimal medical treatment alone in stable patients with moderate…
Current Mechanical Complications of Infarction
Contemporary data of a recently published large registry show that mechanical complications after infarction are not frequent but maintain a very high mortality rate that does not seem to improve over time. Our information on mechanical complications was outdated and we did not have current data on their incidence and prognosis. Such is precisely the…
The Road Towards a “More Perfect” Angioplasty Is Already Being Traveled
The aim of revascularization, whether through angioplasty or surgery, is to restore adequate flow to the myocardium; that much is obvious. However, after millions of “successful” procedures with the best technology applied to drug-eluting stents and optimal medical treatment, we still have a high ratio of patients who experience new events. Could an optimal angiographical…
Should Post-PCI Biomarkers Elevation Be of Concern?
Elevated markers after PCI in stable patients treated with the latest generation stents continues to happen. However, only the association between biomarker elevation with creatine kinase-myocardial band (CK-MB) should be of concern, sin it was associated with mortality at one year. Post procedural cardiac troponin (cTn) elevation was not associated to future events, according to…
Discordance Between FFR and iFR. Which Measurement Is More Important?
In the next days, Dr. Seung Hun and colleagues will publish in J Am Coll Cardiol Intv 2019 a study that answers the title question and also brings peace of mind about the decisions we make based on one of these measurements or the other. This study assessed the physiologic characteristics of discordant lesions between…
TCT 2019 | IVUS-XPL: 5-Year Follow-up for Angiography-vs. IVUS-Guided Angioplasty
Courtesy of SBHCI. The aim of this work, which was presented during the TCT 2019 Scientific Session and simultaneously published in JACC Intv, was to prove the benefit of intravascular ultrasound (IVUS) in angioplasty. The IVUS-XPL trial randomized 1400 patients with long coronary lesions (≥28 mm) to IVUS-guided angioplasty (n = 700) vs. angiography-guided angioplasty (n = 700). All procedures were…
TCT 2019 | AUGUSTUS ACS: Apixaban vs. Warfarin and Aspirin vs. Placebo in AF and ACS
Courtesy of SBHCI. The safety and efficacy of antithrombotic and antiplatelet treatments in patients with atrial fibrillation admitted with acute coronary syndrome (who receive medical treatment or angioplasty) may vary from that in patients undergoing elective treatment. At 14 days from elective angioplasty or hospitalization due to acute coronary syndrome, patients were randomized in a 2×2…
