Comparison of Percutaneous Coronary Intervention (With Drug-Eluting Stents) Versus Coronary Artery Bypass Grafting in Women With Severe Narrowing of …
2014
Women typically present with coronary artery disease later than men with more unfavorable clinical and anatomic characteristics. It is unknown whether differences exist in women undergoing treatment for unprotected left main coronary artery (ULMCA) disease. Our aim was to evaluate long-term clinical outcomes in women treated with percutaneous coronary intervention (PCI) with drug-eluting stents versus coronary artery bypass grafting (CABG). All consecutive women from the Drug-Eluting stent for LefT main coronary Artery disease registry with ULMCA disease were analyzed. A propensity matching was performed to adjust for baseline differences. In total, 817 women were included: 489 (59.8%) unde…
Nonroutine Use of Intra-Aortic Balloon Pump in Cardiogenic Shock Complicating Myocardial Infarction With Successful and Unsuccessful Primary Percutan…
2018
Abstract Objectives The authors sought to compare outcomes of patients with myocardial infarction and cardiogenic shock (CS) treated with percutaneous coronary intervention (PCI) with or without intra-aortic balloon pump (IABP) support according to final epicardial flow in the infarct-related artery. Background A routine use of IABP is contraindicated in patients with myocardial infarction and CS. There are no data regarding the subpopulation of patients who may benefit from such support besides patients with mechanical complications of myocardial infarction. Methods Prospective nationwide registry data of patients with myocardial infarction and CS treated with PCI between 2003 and 2014 wer…
0200: Predictors of angiographically visible distal embolization in ST elevation myocardial infarction patients treated by primary percutaneous coron…
2016
Aspiration thrombectomy during primary percutaneous coronary intervention (p-PCI) in ST elevation myocardial infarction (STEMI) has been proposed to restore myocardial reperfusion. But important controversies remain concerning the usefulness of thrombectomy to improve this perfusion. Our objective was to evaluate the impact of manual thrombectomy on the occur-rence of angiographically visible distal embolization (AVDE) during p-PCI in STEMI. 346 consecutive patients admitted for STEMI who underwent p-PCI and thrombectomy were included. Clinical, angiographic and therapeutics characteristics were assessed. AVDE was defined as an abrupt vessel closure occurring at any point during the PCI pro…
Towards real-time detection of cognitive effort in driving: Contribution of cardiac measurement
2016
En 2013, on estime que 40 à 50% des accidents corporels seraient dus à des défauts d'attention de la part du conducteur. Des études récentes ont mis en évidence la possibilité de détecter des états attentionnels dégradés afin de pouvoir mieux assister le conducteur ; ce thème de recherche représente donc un nouveau gisement de sécurité routière. Cette étude se concentre sur la détection de l'effort cognitif fournit par les conducteurs et cherche, par l'étude de la variation du rythme cardiaque, à identifier un indicateur d'effort sensible sur de courtes fenêtres temporelles.Chacun des 18 participants a passé 8 conditions expérimentales sur simulateur de conduite : la moitié où seule une tâc…
Reperfusion Treatment in an Acute Myocardial Infarction in Patients Older Than 75 Years. Do We Need a Randomized Controlled Trial?
2005
Fibrinolytic therapy in ST-segment elevation acute myocardial infarction (AMI) constitutes one of the most important advances in cardiology in the last 25 years and has influenced the management and evolution of patients as much as the first coronary care units did. The most important limitations of fibrinolytics are the presence of absolute or relative contraindications to their administration in ≤25% of patients, their limited capacity to restore adequate coronary flow and the risk of inducing cerebral hemorrhage. They are at their most efficient in the first 2 hours’ evolution of AMI but lose their efficacy thereafter. 1 Consequently, treatment must be initiated as early as possible and …
Indications of PCSK9 inhibitors in clinical practice. Recommendations of the Spanish Society of Arteriosclerosis (SEA), 2019
2019
A group of experts convened by the Spanish Society of Arteriosclerosis (SEA) has been in charge of updating the SEA document on the indications of PCSK9 inhibitors (PCSK9i) in clinical practice that was published in 2016. This update is justified by the fact that the data from clinical trials carried out on a large scale with PCSK9i have shown that in addition to their high potency to lower atherogenic cholesterol, they reduce the risk of atherosclerotic cardiovascular disease, both in patients with stable disease, and with recent disease, and with a high degree of security. This update provides the recommendations and level of evidence for the prescription of iPCSK9 in patients with homozy…
Long-Term Clinical Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting for Ostial/Midshaft Lesions in Unprotecte…
2014
Objectives The aim of this study was to report the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) for ostial/midshaft lesions in an unprotected left main coronary artery (ULMCA). Background Data regarding outcomes in these patients are limited. Methods Of a total of 2,775 patients enrolled in the DELTA multinational registry, 856 patients with isolated ostial/midshaft lesions in an ULMCA treated by PCI with DES (n = 482) or CABG (n = 374) were analyzed. Results At a median follow-up period of 1,293 days, there were no significant differences in the propensity score-adjusted analyses for …
A Complex Combination of Microvascular and Macrovascular Diseases
2016
When FFR is larger than 0.80, a PCI is not justified. Transient microvascular dysfunction may, however, be associated with impaired hyperemia and falsely negative FFR. This case also emphasizes the dynamic nature of microvascular disease, and provides an example of both “typical” syndrome X and “less conventional” syndrome slow flow associated with increased peripheral resistances (see Chap. 35).
Multiple Lesions, Multiple Measures
2016
This case describes the assessment of FFR in the case of tandem intermediate lesions in the proximal and mid LAD. Hyperemia was induced with intravenous (IV) infusion of Adenosine, which allows pullback measurements. First, with the wire placed distal in the vessel, FFR provides information on whether the sum of the two stenoses causes ischemia. Thereafter, during pullback, the most severe stenosis can be identified as the most relevant pressure drop. Finally, a re-evaluation of FFR is important after PCI: after the first stenosis is treated, the degree of hyperemia achievable will be larger, thus unmasking the relevance of the second one.
