Recent studies are further confirming this hypothesis, suggesting that the clinical benefit of the fractional flow reserve-guided strategy is simply due to a significant reduction in the rate of repeated revascularizations, with no significant differences in the incidence of hard endpoints. There is a need to develop new randomized studies, requiring a feasible number of patients, to test the superiority of an approach based on vulnerable plaque sealing and treatment.Can imaging provide sufficient risk stratification to warrant revascularization of a stable plaque with negative fractional flow reserve (FFR)? Prophylactic stenting could at best be applied selectively since the composite group of FFR-negative lesions has a death or myocardial infarction rate of approximately 1%/year or less but modern stents have a rate of 2% to 3.5%/year. Because vulnerable features exist in a minority of lesions, at least 9,000 patients must be screened in order to enroll a cohort with sufficient risk. While several ongoing randomized trials are testing the concept of plaque sealing in FFR-negative lesions, preventive stenting depends on such a small effect that sample sizes to validate or refute its benefit become prohibitive. Since FFR provides a quantitative, straightforward, and reproducible metric of plaque vulnerability and burden without the need for or expense of additional catheter devices, intracoronary imaging cannot meaningfully guide prophylactic stenting when faced with a negative FFR.
The aim of this study was to compare ticagrelor monotherapy with dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug-eluting stents.
The role of abbreviated DAPT followed by an oral P2Y
inhibitor after PCI remains uncertain.
Two randomized trials, including 14,628 patients undergoing PCI, comparing ticagrelor monotherapy with standard DAPT on centrally adjudicated endpoints were identified, and individual patient data were analyzed using 1-step fixed-effect models. The protocol was registered in PROSPERO (CRD42019143120). The primary outcomes were the composite of Bleeding Academic Research Consortium type 3 or 5 bleeding tested for superiority and, if met, the composite of all-cause death, myocardial infarction, or stroke at 1 year, tested for noninferiority against a margin of 1.25 on a hazard ratio (HR) scale.
Bleeding Academic Research Consortium type 3 or 5 bleeding occurred in fewer patients with ticagrelor than DAPT (0.9% vs. 1.7%, respectively; HR 0.56; 95% confidence interval [CI] 0.41 to 0.75; p<0.001). The composite of all-cause death, myocardial infarction, or stroke occurred in 231 patients (3.2%) with ticagrelor and in 254 patients (3.5%) with DAPT (HR 0.92; 95%CI 0.76 to 1.10; p<0.001 for noninferiority). https://www.selleckchem.com/products/arv-825.html Ticagrelor was associated with lower risk for all-cause (HR 0.71; 95%CI 0.52 to 0.96; p=0.027) and cardiovascular (HR 0.68; 95%CI 0.47 to 0.99; p=0.044) mortality. Rates of myocardial infarction (2.01% vs. 2.05%; p=0.88), stent thrombosis (0.29% vs. 0.38%; p=0.32), and stroke (0.47% vs. 0.36%; p=0.30) were similar.
Ticagrelor monotherapy was associated with a lower risk for major bleeding compared with standard DAPT, without a concomitant increase in ischemic events.

The aim of this study was to assess whether the effects of ticagrelor monotherapy after 3-month dual-antiplatelet therapy (DAPT) are consistent among patients presenting with ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction, and unstable angina treated with drug-eluting stents.
Ticagrelor monotherapy after short-term DAPT has not been investigated in patients with STEMI.
This was a pre-specified, stratified, subgroup analysis of the STEMI cohort from the TICO (Ticagrelor Monotherapy After 3 Months in the Patients Treated With New Generation Sirolimus Stent for Acute Coronary Syndrome) trial, which constituted 36% of the total population. The primary outcome was a composite of major bleeding and major adverse cardiac and cerebrovascular events (MACCE; death, myocardial infarction, stent thrombosis, stroke, or target vessel revascularization). The secondary outcomes were major bleeding and MACCE.
The incidence of the primary outcome was 4.4% in patients r Monotherapy After 3 Months in the Patients Treated With New Generation Sirolimus Stent for Acute Coronary Syndrome [TICO Study]; NCT02494895).
This pre-specified subgroup analysis revealed no heterogeneity in the effects of ticagrelor monotherapy after 3-month DAPT, compared with 12-month DAPT, for the primary outcome, major bleeding, and MACCE across clinical presentations including STEMI, though larger studies are needed to demonstrate these findings with adequate power. (Ticagrelor Monotherapy After 3 Months in the Patients Treated With New Generation Sirolimus Stent for Acute Coronary Syndrome [TICO Study]; NCT02494895).
The objective of this study was to assess contemporary use of operator directed sedation (ODS) and anesthesiologist care (AC) in the pediatric/congenital cardiac catheterization laboratory (PCCL), specifically evaluating whether the use of operator-directed sedation was associated with increased risk of major adverse events.
The safety of ODS relative to AC during PCCL procedures has been questioned.
A multicenter, retrospective cohort study was performed studying procedures habitually performed with ODS or AC at IMPACT (Improving Adult and Congenital Treatment) registry hospitals using ODS for≥5% of cases. The risks for major adverse events (MAE) for ODS and AC cases were compared, adjusted for case mix. Current recommendations were evaluated by comparing the ratio of observed to expected MAE for cases in which ODS was inappropriate (inconsistent with those guidelines) with those for similar risk AC cases, as well as those in which ODS or AC was appropriate.
Of the hospitals submitting data to IMPACTciency. Clinical judgment better identified cases in which ODS could be used than pre-procedural risk score. This should inform future guidelines for the use of ODS and AC in the catheterization laboratory.
