Despite improvement in operative and cerebral perfusion techniques, cerebral malperfusion and neurological injury remain a dreaded complication of acute type A aortic dissection. We aimed to identify predictors for postoperative stroke and analyse the impact on morbidity, neurological recovery and mid-term survival. Between 2000 and 2017, 303 (71.9% men, mean age 58.9 ± 13.6 years) patients with acute type A aortic dissection underwent surgical repair. Clinical and imaging data were retrospectively evaluated. Patients were divided into 2 groups depending on the presence of postoperative stroke. Postoperative stroke was detected in 15.8% (n = 48) of the patients. Patients with postoperative stroke showed higher rates of preoperative cardiopulmonary resuscitation (stroke: 18.8% vs no stroke: 3.5%, P < 0.001) and malperfusion syndrome (stroke: 47.9% vs no stroke: 22.4%, P < 0.001). Multivariable analysis identified the presence of bovine aortic arch [odds ratio (OR) 2.33, 95% confidence interval (CI) 1.086–4.998; P = 0.030], preoperative cardiopulmonary resuscitation (OR 6.483, 95% CI 1.522–27.616; P = 0.011) and preoperative malperfusion (OR 2.536, 95% CI 1.238–5.194; P = 0.011) as independent predictors for postoperative stroke. Postoperative stroke had a strong impact on morbidity and was associated with higher rates of postoperative complications and a significantly longer hospital stay (stroke: 23 ± 16 days vs no stroke: 17 ± 18 days, P = 0.021). Postoperative stroke was not independently associated with in-hospital mortality (adjusted OR 1.382, 95% CI 0.518–3.687; P = 0.518). There was no difference in mid-term survival between patients with stroke and patients without stroke. This study identified independent preoperative predictors for postoperative stroke. Although postoperative stroke was associated with significant morbidity and postoperative complications, significant impairment in mid-term survival could not be confirmed by the data.
Cardiac magnetic resonance (CMR) is the gold-standard modality for the assessment of left ventricular (LV) remodeling in ST-elevation myocardial infarction (STEMI) patients. However, the commonly used remodeling criteria have never been validated for hard clinical events. We therefore aimed to define clear CMR criteria of LV remodeling following STEMI with proven prognostic impact.

OBJECTIVES: Surgical therapy for acute aortic dissection type A (AADA) in octogenarians carries high morbidity and mortality. The role of isolated medical treatment in this setting is controversial. The aim of this study is to determine whether risk of surgery for AADA outweighs risk of death from medical treatment only. METHODS: From 2002 to 2015, 90 consecutive octogenarians (mean age, 83.5 ± 3 years) were treated for AADA at three institutions: 67 patients underwent surgery, 23 patients received medical treatment. Analysis of early and late outcome was performed. RESULTS: Patients in the medical treatment group were significantly older than in the surgical group (84.9 ± 3.7 vs 83 ± 2.5 years, P = 0.008) and in a more critical state. In patients undergoing surgical repair, perioperative mortality was 14.9% (n = 10). Rate of prolonged ventilation (63.2% vs 5.9%; P < 0.001) and renal failure (35.1% vs 5.9%, P = 0.029) was significantly higher in the surgical group. Thirty-day survival was impaired in the medical treatment group (34.8% vs 61.2% in the surgical group; P = 0.032). Coronary artery disease (OR 3.95, 95% CI 1.16–13.49; P = 0.029) and complicated dissections (OR 5.28, 95% CI 1.48–18.88; P = 0.010)—composite variable of preoperative resuscitation, neurological injury and malperfusion—emerged as independent risk factors for 30-day mortality in the surgical group. There was no difference in long-term survival. CONCLUSIONS: Emergency surgery for AADA in octogenarians is associated with relatively high intraoperative mortality and may reasonably be avoided in patient with complicated presentation. Despite better immediate survival after surgery, long-term survival does not differ between medical and surgical patients, reflecting the extremely advanced point in life cycle octogenarians.

The left ventricular global function index (LVGFI) is a novel indicator of left ventricular performance. Its prognostic value in patients after ST-segment elevation myocardial infarction (STEMI) is unknown. We sought to evaluate the prognostic significance of LVGFI measured by cardiovascular magnetic resonance (CMR) imaging after STEMI. Two hundred eligible STEMI patients (56 ± 11 years, 16% female) revascularized by primary percutaneous coronary intervention were followed-up for 3.1 [2–4.1] years for major adverse cardiac events (MACE). MACE was defined as a composite of death, non-fatal myocardial re-infarction, and new congestive heart failure. All patients underwent CMR imaging within 2 [2–4] days after STEMI. Late enhancement and cine images were acquired to assess myocardial injury as well as myocardial function, including LVGFI. Patients suffering a MACE event ( n = 20, 10%) had a significantly lower LVGFI ( P = 0.001). In Kaplan–Meier analysis, a decreased LVGFI was associated with a reduced MACE-free survival ( P < 0.001). Multivariate Cox regression analysis revealed a decreased LVGFI as a predictor for MACE [hazard ratio = 4.79, 95% confidence interval (CI) 1.46–15.67, P = 0.010] after adjusting for microvascular obstruction, left ventricular mass, and multivessel disease. In receiver operating characteristic analysis, LVGFI was a strong predictor for MACE (area under the curve = 0.73, CI 0.61–0.85). However, c -statistics revealed that LVGFI does not provide incremental prognostic information over left ventricular ejection fraction (LVEF) ( P = 0.38). LVGFI assessed by CMR is a strong predictor of MACE within 3 years after first STEMI. A superior predictive value as compared with LVEF was not found in this study.
