Ten-year clinical outcomes in patients with intermediate coronary stenosis according to the combined culprit lesion.

ABSTRACT:

Background

We assessed the long-term clinical outcomes of an intermediate lesion (IL) according to the presence of a combined culprit lesion (CCL).

Hypothesis

Long-term clinical outcomes of IL may be affected by the presence of a CCL.

Methods

Angiographic findings (n = 1096) and medical chart were reviewed. Patients with IL were divided into two groups: IL without CCL group (n = 383, 64.5%) and IL with CCL group (n = 211, 35.5%).

Results

The major adverse cardiovascular events (MACE) in the IL with CCL group were significantly higher than those in the IL without CCL group (death: 12.3% vs. 7.0%, myocardial infarction: 3.3%vs. 0.5%, stroke: 6.6% vs. 2.6%, and revascularization [RVSC]: 25.1% vs. 7.6%) during a mean follow up period of 118.4 ± 5.5 months. IL related RVSC rate in the IL with CCL group was higher than that in the IL without CCL group (5.7% vs. 2.1%, p = 0.020). RVSC rate related to IL in total subjects was lower than that related to stented lesion (3.4% vs. 6.4%). The important predictors of total MACE in total subjects were the presence of CCL, IL percent diameter stenosis, hypertension, history of percutaneous coronary intervention, blood glucose and ejection fraction. The predictors of IL related RVSC were IL percent diameter stenosis and IL located in the right coronary artery.

Conclusion

10-year clinical outcomes of an IL (especially IL without CCL) were better than those of stented lesions. This study suggests that the IL can be safely followed up in sites that do not have ability to assess functional study.

Project description:ImportanceMyocardial infarction with a culprit lesion located in the left main or proximal left anterior descending artery compared with other coronary segments is associated with more myocardium at risk and worse clinical outcomes.ObjectiveTo evaluate the association of culprit lesion location with outcomes of culprit-lesion-only percutaneous coronary intervention with optional staged revascularization vs immediate multivessel percutaneous coronary intervention in patients with multivessel disease, myocardial infarction, and cardiogenic shock.Design, setting, and participantsPost hoc analysis of the Culprit Lesion Only Coronary Intervention vs Multivessel Coronary Intervention in Cardiogenic Shock (CULPRIT-SHOCK), an investigator-initiated randomized, open-label clinical trial. Patients with multivessel disease, acute myocardial infarction, and cardiogenic shock were enrolled at 83 European centers from April 2013 through April 2017.InterventionsPatients were randomized to culprit-lesion-only percutaneous coronary intervention with optional staged revascularization or immediate multivessel percutaneous coronary intervention (1:1). For this analysis, patients were stratified by culprit lesion location in the left main or proximal left anterior descending artery group and other-culprit-lesion location group.Main outcomes and measuresEnd points included a composite of death or kidney replacement therapy at 30 days and death at 1 year.ResultsThe median age of the study population was 70 (interquartile range, 60-78 years) and 524 of the study participants were men (76.4%). Of the 685 patients, 33.4% constituted the left main or proximal left anterior descending artery group and 66.6% the other-culprit-lesion location group. The left main or proximal left anterior descending artery group had worse outcomes compared with the other-culprit-lesion location group (56.8% vs 47.5%; P = .02 for the composite end point at 30 days and 59.8% vs 50.1%; P = .02 for death at 1 year). In both groups, culprit-lesion-only vs immediate multivessel percutaneous coronary intervention was associated with a reduced risk of the composite end point at 30 days (49.1% vs 64.3% and 44.1% vs 50.9%; P for interaction = .27). At 1 year, culprit-lesion-only vs immediate multivessel percutaneous coronary intervention was associated with a significantly reduced risk of death in the left main or proximal left anterior descending artery but not the other-culprit-lesion location group (50.0% vs 69.6%; P = .003 and 49.8% vs 50.4%; P = .89; P for interaction = 0.02).Conclusions and relevanceIn patients with multivessel disease with myocardial infarction and cardiogenic shock, a culprit lesion located in the left main or proximal left anterior descending artery vs other coronary segments was associated with worse outcomes. These patients may especially benefit from culprit-lesion-only percutaneous coronary intervention with optional staged revascularization, although further investigation is needed to confirm this finding.Trial registrationClinicalTrials.gov Identifier: NCT01927549.

Project description:Background Despite advances in devices and techniques, coronary bifurcation lesion remains a challenging lesion subset in the field of percutaneous coronary intervention (PCI). We evaluate 10-year trends in bifurcation PCI and their effects on patient outcomes. Methods and Results We analyzed 10-year trends in patient/lesion characteristics, devices, PCI strategy, stent optimization techniques, and clinical outcomes using data from 5498 patients who underwent bifurcation PCI from 2004 to 2015. Clinical outcomes 2 years after the index procedure were evaluated in terms of target vessel failure (a composite of cardiac death, myocardial infarction, and target vessel revascularization) and a patient-oriented composite outcome (a composite of all-cause death, myocardial infarction, and any revascularization). During the 10-year study period, patient and lesion complexity, such as multivessel disease, diabetes mellitus, chronic kidney disease, and left main bifurcation, increased continuously (all P<0.001). The risk of target vessel failure or patient-oriented composite outcome decreased continuously from 2004 to 2015 (target vessel failure: from 12.3% to 6.9%, log-rank P<0.001; patient-oriented composite outcome: from 13.6% to 9.3%, log-rank P<0.001). The use of a second-generation drug-eluting stent and decreased target vessel failure risk in true bifurcation lesions were the major contributors to improved patient prognosis (interaction P values were <0.001 and 0.013, respectively). Conclusions During the past decade of bifurcation PCI, patient and lesion characteristics, devices, PCI techniques, and patient prognosis have all significantly changed. Despite increased patient and lesion complexity, clinical outcomes after bifurcation PCI have improved, mainly because of better devices and more widespread adoption of procedural optimization techniques and appropriate treatment strategies.

Project description:Background:No proper data on prognosis and management of type-2 diabetic ST elevation myocardial infarction (STEMI) patients with culprit obstructive lesion and multivessel non obstructive coronary stenosis (Mv-NOCS) exist. We evaluated the 12-months prognosis of Mv-NOCS-diabetics with first STEMI vs.to non-diabetics, and then Mv-NOCS-diabetics previously treated with incretin based therapy vs. a matched cohort of STEMI-Mv-NOCS never treated with such therapy. Methods:1088 Patients with first STEMI and Mv-NOCS were scheduled for the study. Patients included in the study were categorized in type 2 diabetics (n 292) and non-diabetics (n 796). Finally, we categorized diabetics in current-incretin-users (n 76), and never-incretin-users (n 180). The primary end point was all cause deaths, cardiac deaths, and major adverse cardiac events (MACE) at 12 months of follow up. Results:The study results evidenced higher percentage of all cause deaths (2.2% vs. 1.1%, p value 0.05), cardiac deaths (1.6% vs. 0.5%, p value 0.045), and MACE (12.9% vs. n 5.9%), p value 0.001) in diabetic vs. no diabetic patients at 12 months follow up. Among diabetic patients, the current vs never-incretin-users, did not present a significant difference about all cause of deaths, and cardiac deaths through 12-months. The MACE rate at 1 year was 7.4% in diabetic incretin-users STEMI Mv-NOCS patients vs. 12.9% in diabetic never-incretin-users STEMI-Mv-NOCS patients (p value 0.04). In a risk-adjusted hazard analysis, MACE through 12 months were lower in diabetic STEMI-Mv NOCS incretin-users vs never-incretin-users patients (HR 0.513, CI [0.292-0.899], p 0.021). Consequently, lower levels of glucagon-like peptide 1(GLP-1) were predictive of MACE at follow up (HR 1.528, CI [1.059-2.204], p 0.024). Conclusion:In type 2 diabetic patients with STEMI-Mv-NOCS, we observed higher incidence of 1-year mortality and adverse cardiovascular outcomes, as compared to non-diabetic STEMI-Mv-NOCS patients. In diabetic patients, never-incretin-users have worse prognosis as compared to current-incretin-users.Trail registration Clinical trial number: NCT03312179, name of registry: clinicaltrialgov, URL: clinicalltrialgov.com, date of registration: September 2017, date of enrollment first participant: September 2009.
