Comparison of six risk scores in patients with triple vessel coronary artery disease undergoing PCI: competing factors influence mortality, myocardial infarction, and target lesion revascularization.

ABSTRACT: To compare the discriminatory value of differing risk scores for predicting clinical outcomes following PCI in routine practice.Various risk scores predict outcomes after PCI. However, these scores consider markedly different factors, from purely anatomical (SYNTAX risk score [SRS]) to purely clinical (ACEF, modified ACEF [ACEFmod], NCDR), while other scores combine both elements (Clinical SYNTAX score [CSS], NY State Risk Score [NYSRS]).Patients with triple vessel and/or LM disease with 12 month follow-up were studied from a single center PCI registry. Exclusion criteria included STEMI presentation, prior revascularization and shock. Clinical events at 12 months were compared to baseline risk scores, according to score tertiles and area under receiver-operating-characteristic curves (AUC).We identified 584 eligible patients (69.8±12.3yrs, 405 males). All scores were predictive of mortality, with the SRS being least predictive (AUC=0.66). The most accurate scores for mortality were the CSS and ACEF (AUC=0.76 for both: P = 0.019 and 0.08 vs. SRS, respectively). For TLR, while the SRS trended toward being positively predictive (P = 0.075), several scores trended towards a negative association, which reached significance for the NCDR (P = 0.045). The SRS and CSS were the only scores predictive of MI (both P < 0.05). No score was particularly accurate for predicting MACE (death+MI+TLR), with AUCs ranging from 0.53 (NCDR) to 0.63 (SRS).Competing factors influence mortality, MI and TLR after PCI. An increasing burden of comorbidities is associated with mortality, whereas anatomical complexity predicts MI. By combining these outcomes to predict MACE, all scores show reduced utility.

Project description:Background In ST-segment-elevation myocardial infarction, angiography-based complete revascularization is superior to culprit-lesion-only percutaneous coronary intervention. Quantitative flow ratio (QFR) is a novel, noninvasive, vasodilator-free method used to assess the hemodynamic significance of coronary stenoses. We aimed to investigate the incremental value of QFR over angiography in nonculprit lesions in patients with ST-segment-elevation myocardial infarction undergoing angiography-guided complete revascularization. Methods and Results This was a retrospective post hoc QFR analysis of untreated nontarget vessels (any degree of diameter stenosis [DS]) from the randomized multicenter COMFORTABLE AMI (Comparison of Biolimus Eluted From an Erodible Stent Coating With Bare Metal Stents in Acute ST-Elevation Myocardial Infarction) trial by assessors blinded for clinical outcomes. The primary end point was cardiac death, spontaneous nontarget vessel myocardial infarction, and clinically indicated nontarget vessel revascularization (ie, ≥70% DS by 2-dimensional quantitative coronary angiography or ≥50% DS and ischemia) at 5 years. Of 1161 patients with ST-segment-elevation myocardial infarction, 946 vessels in 617 patients were analyzable by QFR. At 5 years, the rate of the primary end point was significantly higher in patients with QFR ≤0.80 (n=35 patients, n=36 vessels) versus QFR >0.80 (n=582 patients, n=910 vessels) (62.9% versus 12.5%, respectively; hazard ratio [HR], 7.33 [95% CI, 4.54-11.83], P<0.001), driven by higher rates of nontarget vessel myocardial infarction (12.8% versus 3.1%, respectively; HR, 4.38 [95% CI, 1.47-13.02], P=0.008) and nontarget vessel revascularization (58.6% versus 7.7%, respectively; HR, 10.99 [95% CI, 6.39-18.91], P<0.001) with no significant differences for cardiac death. Multivariable analysis identified QFR ≤0.80 but not ≥50% DS by 3-dimensional quantitative coronary angiography as an independent predictor of the primary end point. Results were consistent, including only >30% DS by 3-dimensional quantitative coronary angiography. Conclusions Our study suggests incremental value of QFR over angiography-guided percutaneous coronary intervention for nonculprit lesions among patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Project description:ImportanceRecently, the Complete vs Culprit-Only Revascularization to Treat Multivessel Disease After Early PCI (percutaneous coronary intervention) for STEMI (ST-segment elevation myocardial infarction [MI]) (COMPLETE) trial showed that angiography-guided PCI of the nonculprit lesion with the goal of complete revascularization reduced cardiovascular (CV) death or new MI compared with PCI of the culprit lesion only in STEMI. Whether complete revascularization also reduces CV mortality is uncertain. Moreover, whether the association of complete revascularization with hard clinical outcomes is consistent when fractional flow reserve (FFR)- and angiography-guided strategies are used is unknown.ObjectiveTo determine through a systematic review and meta-analysis (1) whether complete revascularization is associated with decreased CV mortality and (2) whether heterogeneity in the association occurs when FFR- and angiography-guided PCI strategies for nonculprit lesions are performed.Data sourcesA systematic search of MEDLINE, Embase, ISI Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) from database inception to September 30, 2019, was performed. Conference proceedings were also reviewed from January 1, 2002, to September 30, 2019.Study selectionEnglish-language randomized clinical trials comparing complete revascularization vs culprit-lesion-only PCI in patients with STEMI and multivessel disease were included.Data extraction and synthesisThe combined odds ratio (OR) was calculated with the random-effects model using the Mantel-Haenszel method (sensitivity with fixed-effects model). Heterogeneity was measured using the I2 statistic. Publication bias was evaluated using the inverted funnel plot approach. Data were analyzed from October 2019 to January 2020.Main outcomes and measuresCardiovascular death and the composite of CV death or new MI.ResultsTen randomized clinical trials involving 7030 unique patients were included. The weighted mean follow-up time was 29.5 months. Complete revascularization was associated with reduced CV death compared with culprit-lesion-only PCI (80 of 3191 [2.5%] vs 106 of 3406 [3.1%]; OR, 0.69 [95% CI, 0.48-0.99]; P = .05; fixed-effects model OR, 0.74 [95% CI, 0.55-0.99]; P = .04). All-cause mortality occurred in 153 of 3426 patients (4.5%) in the complete revascularization group vs 177 of 3604 (4.9%) in the culprit-lesion-only group (OR, 0.84 [95% CI, 0.67-1.05]; P = .13; I2 = 0%). Complete revascularization was associated with a reduced composite of CV death or new MI (192 of 2616 [7.3%] vs 266 of 2586 [10.3%]; OR, 0.69 [95% CI, 0.55-0.87]; P = .001; fixed-effects model OR, 0.69 [95% CI, 0.57-0.84]; P < .001), with no heterogeneity in this outcome when complete revascularization was performed using an FFR-guided strategy (OR, 0.78 [95% CI, 0.43-1.44]) or an angiography-guided strategy (OR, 0.61 [95% CI, 0.38-0.97]; P = .52 for interaction).Conclusions and relevanceIn patients with STEMI and multivessel disease, complete revascularization was associated with a reduction in CV mortality compared with culprit-lesion-only PCI. There was no differential association with treatment between FFR- and angiography-guided strategies on major CV outcomes.

Project description:AimsThe prognostic importance of cardiac procedural myocardial injury and myocardial infarction (MI) in chronic coronary syndrome (CCS) patients undergoing elective percutaneous coronary intervention (PCI) is still debated.Methods and resultsWe analysed individual data of 9081 patients undergoing elective PCI with normal pre-PCI baseline cardiac troponin (cTn) levels. Multivariate models evaluated the association between post-PCI elevations in cTn and 1-year mortality, while an interval analysis evaluated the impact of the size of the myocardial injury on mortality. Our analysis was performed in the overall population and also according to the type of cTn used [52.0% had high-sensitivity cTn (hs-cTn)]. Procedural myocardial injury, as defined by the Fourth Universal Definition of MI (UDMI) [post-PCI cTn elevation ≥1 × 99th percentile upper reference limit (URL)], occurred in 52.8% of patients and was not associated with 1-year mortality [adj odds ratio (OR), 1.35, 95% confidence interval (CI) (0.84-1.77), P = 0.21]. The association between post-PCI cTn elevation and 1-year mortality was significant starting ≥3 × 99th percentile URL. Major myocardial injury defined by post-PCI ≥5 × 99th percentile URL occurred in 18.2% of patients and was associated with a two-fold increase in the adjusted odds of 1-year mortality [2.29, 95% CI (1.32-3.97), P = 0.004]. In the subset of patients for whom periprocedural evidence of ischaemia was collected (n = 2316), Type 4a MI defined by the Fourth UDMI occurred in 12.7% of patients and was strongly associated with 1-year mortality [adj OR 3.21, 95% CI (1.42-7.27), P = 0.005]. We also present our results according to the type of troponin used (hs-cTn or conventional troponin).ConclusionOur analysis has demonstrated that in CCS patients with normal baseline cTn levels, the post-PCI cTn elevation of ≥5 × 99th percentile URL used to define Type 4a MI is associated with 1-year mortality and could be used to detect 'major' procedural myocardial injury in the absence of procedural complications or evidence of new myocardial ischaemia.
