Evolocumab, a PCSK9 inhibitor, has shown significant reduction of complex coronary disease requiring revascularization (be it PCI or CABG). Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors induce plaque regression and could eventually reduce the risk of coronary revascularization, especially complex revascularization. The FOURIER study randomized 27564 patients with stable CAD already on statins to evolocumab…
Ticagrelor to Improve Venous Graft Patency
Saphenous vein graft patency is one of CABG’s “Achilles heals”, especially after the ARTS trial came out showing bilateral internal mammary artery grafting was not superior to simple internal mammary artery grafting. Antiaggregation more potent than aspirin might prolong venous graft patency in cases when the available techniques will fail to improve poor outcomes. Previous…
ESC 2020 | At Long Term, Diabetic Patients Benefit from Surgery
Data of this “real world” study have confirmed that diabetic patients with multivessel disease will benefit from coronary artery bypass grafting (CABG). According to Dr. Douglas S. Lee, main author of this study, the evidence is fairly conclusive, enough to recommend CABG as first option in this particular subgroup of patients similar to FREEDOM patients. …
More Data from the EXCEL and More Controversy
A thorough statistical analysis of the EXCEL has quite definitely shown that the likelihood of death, MI or stoke, including total mortality, is higher with PCI compared against CABG. The Bayesian analysis estimated a 3.3% difference in mortality, superior in the PCI arm, with 99% probability that EXCEL total mortality was indeed increased with PCI…
Should We Finalize TAVR with Atrial Pacing in Some Patients?
Courtesy of Dr. Carlos Fava. The benefits of transcatheter aortic valve replacement (TAVR) are undoubtedly clear, but implantation is performed near the atrioventricular (AV) node, the bundle of His, and the left bundle branch. Consequently, permanent pacemaker implantation (PPI) after TAVR or surgical aortic valve replacement becomes necessary. While researchers have recently developed strategies to reduce…
Virtual ACC 2020 | PRECOMBAT: 10 Years for Surgery vs. Angioplasty in Left Main Coronary Artery Disease
After 10 years of follow-up, there were no significant differences in the rates of major adverse cardiovascular or cerebrovascular events among patients with left main coronary artery disease randomized to angioplasty or surgery. Since this was the first study to randomize patients with left main coronary artery disease to angioplasty or surgery, it enrolled very few…
Angioplasty in Long Femoropopliteal Lesions Offers Reasonable Results
Courtesy of Dr. Carlos Fava. Around half the treated lesions in peripheral disease are femoropopliteal lesions. Long lesions are among the challenges faced: they are associated with higher mortality and morbidity, and revascularization in that setting always entails some degree of difficulty. Nowadays, with the development of nitinol stents and more operator experience, angioplasty is becoming…
Soon after the EXCEL “Scandal” the NOBLE 5-year Outcomes Come Out: Mere Coincidence?
There is no such thing as coincidence, at least not for the evidence-based medical science. This is what the NOBLE 5-year outcomes, soon to be published in the Lancet, seem to say, in line with the BBC exposé of the EXCEL study. The NOBLE study randomized patients with left main disease to compare PCI vs…
Latest Guidelines “Dropped” After Scandal Over EXCEL Results
The European Association for Cardio-Thoracic Surgery (EACTS) formally withdrew its support for the latest coronary revascularization guidelines following a BBC investigation suggesting that data from the EXCEL trial might have been manipulated. The recommendations for left main coronary artery revascularization featured in the 2018 guidelines, which were written jointly with the European Society of Cardiology…
The EXCEL Authors’ Answer to the BBC Investigation
Do to an investigation carried out by the BBC that led to the withdrawal of EACTS support from the latest coronary revascularization guidelines, the authors of the EXCEL study (indicated by this research) provided the following answers. -Defining Peri-Procedural Infarction: All researchers involved (including surgeons) agreed that the universal definition of infarction was not right…
