Abstract
BACKGROUND In ST-elevation myocardial infarction (STEMI) in patients with multivessel disease, there is a lack of consensus regarding the importance of complete revascularization and the timing of treatment of nonculprit stenoses. Our objective was to investigate the impact of incomplete revascularization in STEMI patients using the residual Synergy Between PCI with TAXUS and Cardiac Surgery score (rSS) to define completeness of revascularization. METHODS This study examined associations between incomplete revascularization, determined by the rSS, and the combined outcome of cardiac death and myocardial infarction (MI). Patients were divided into groups: rSS = 0 (complete revascularization), rSS = 1-8 (incomplete revascularization with a low burden of residual disease), or rSS >8 (incomplete revascularization with a high burden of residual disease). RESULTS The rSS score was calculated in 589 consecutive patients; 25% had an rSS of 0, 42% rSS 1-8, and 33% rSS >8. At median follow-up of 3.5 years, cardiac death and MI occurred in 5% of rSS = 0 patients, 15% rSS = 1-8, and 26% with rSS >8 (P < .001). The rSS was powerful independent predictor of cardiac death and MI (hazard ratio 5.05, CI 2.89-12.00, rSS >8 vs rSS 0, P < .001 and hazard ratio 2.96, CI 1.31-6.69, rSS = 1-8 vs rSS = 0, P = .009), respectively, and an independent predictor of mortality, MI, unplanned revascularization, and major adverse cardiovascular events. CONCLUSIONS In patients with STEMI, the rSS independently predicts cardiac death and MI. Patients with an rSS >8 had substantially higher rates of cardiac death or MI. The rSS can be used to define incomplete revascularization in STEMI and predict adverse outcomes.

Clinical and Angiographic Predictors of Mortality in Sudden Cardiac Arrest Patients Having Cardiac Catheterisation: A Single Centre Registry. Heart Lung Circ 2018; 28:370-378. [PMID: 29459218 DOI: 10.1016/j.hlc.2018.01.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2017] [Revised: 12/21/2017] [Accepted: 01/09/2018] [Indexed: 11/28/2022]
Abstract
BACKGROUND Immediate cardiac catheterisation (CC) is recommended in ST-elevation myocardial infarction (STEMI) following sudden cardiac arrest (SCA). Guidelines advise urgent CC for SCA patients without-STEMI, at clinician discretion. We examined the clinical and angiographic factors predicting mortality in SCA patients having CC. METHODS Consecutive SCA patients having CC at Liverpool Hospital, Sydney (January 2011-September 2015) were retrospectively analysed. Patient data were retrieved from hospital records, and angiographic SYNTAX scores (SS) were quantified online. Independent predictors of mortality were derived using multivariate logistic analysis. RESULTS The study cohort comprised 104 SCA patients; mean age 61±12years, and 79% male. Immediate CC (<2hours post-SCA) was performed in 35% overall. Compared to the without-STEMI subgroup, STEMI patients had more ventricular fibrillation (91 vs 50%; p<0.0001), and higher mean peak serum high-sensitivity troponin-T (8.25±14.7 vs 1.97±6.13 ug/L; p=0.006); in the context of higher median SS (18 vs 6.5; p=0.002) and target-lesion SS (tSS, 10 vs 0; p<0.001). Percutaneous coronary intervention (PCI; 75 vs 23%; p<0.0001) and target vessel revascularisation (11 vs 0%; p=0.005) were more frequent for STEMI. All-cause mortality was 39%, at 1.3±1.5years follow-up. Independent mortality predictors were: delayed CC (HR 4.08), serum lactate >7mmol/L (HR 3.47), and tSS (HR 1.05). CONCLUSIONS Elevated serum lactate, tSS, and delayed CC, were predictive of longer-term mortality in SCA patients having CC. Late CC in patients without-STEMI suggest scope for improvement in real-world systems of care. Closer scrutiny of target lesion complexity may aid prognostication in SCA survivors.
