  • Stroke in acute type A aortic dissection : the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD)

    • OBJECTIVES: Stroke is a serious complication in patients with acute type A aortic dissection (ATAAD). Previous studies investigating stroke in ATAAD patients have been limited by small cohorts and have shown diverging results. We sought to identify risk factors for stroke and to evaluate the effect of stroke on outcomes in surgical ATAAD patients. METHODS: The Nordic Consortium for Acute Type A Aortic Dissection database included patients operated for ATAAD at 8 Scandinavian Hospitals between 2005 and 2014. RESULTS: Stroke occurred in 177 (15.7%) out of 1128 patients. Patients with stroke presented more frequently with cerebral malperfusion (20.6% vs 6.3%, P < 0.001), syncope (30.6% vs 17.6%, P < 0.001), cardiogenic shock (33.1% vs 20.7%, P < 0.001) and pericardial tamponade (25.9% vs 14.7%, P < 0.001) and more often underwent total aortic arch replacement (10.7% vs 4.7%, P = 0.016), compared to patients without stroke. In the 86 patients presenting with cerebral malperfusion, 38.4% developed stroke. Thirty-day and 5-year mortality in patients with and without stroke were 27.1% vs 13.6% and 42.9% vs 25.6%, respectively. Stroke was an independent predictor of early- [odds ratio 2.02, 95% confidence interval (CI) 1.34-3.05; P < 0.001] and midterm mortality (hazard ratio 1.68, 95% CI 1.27-2.23; P < 0.001). CONCLUSIONS: Stroke in ATAAD patients is associated with increased early- and midterm mortality. Preoperative cerebral malperfusion and impaired haemodynamics, as well as total aortic arch replacement, were more frequent among patients who developed stroke. Importantly, a large proportion of patients presenting with cerebral malperfusion did not develop a permanent stroke, indicating that signs of cerebral malperfusion should not be considered a contraindication for surgery.

  • Preoperative dual antiplatelet therapy increases bleeding and transfusions but not mortality in acute aortic dissection type A repair.
  • 2019
  • Ingår i: European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery. - : Oxford University Press (OUP). - 1873-734X .- 1010-7940. ; 56:1, s. 182-188

    • Acute aortic dissection type A is a life-threatening condition, warranting immediate surgery. Presentation with sudden chest pain confers a risk of misdiagnosis as acute coronary syndrome resulting in subsequent potent antiplatelet treatment. We investigated the impact of dual antiplatelet therapy (DAPT) on bleeding and mortality using the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) database.The NORCAAD database is a retrospective multicentre database where 119 of 1141 patients (10.4%) had DAPT with ASA + clopidogrel (n = 108) or ASA + ticagrelor (n = 11) before surgery. The incidence of major bleeding and 30-day mortality was compared between DAPT and non-DAPT patients with logistic regression models before and after propensity score matching.Before matching, 51.3% of DAPT patients had major bleeding when compared to 37.7% of non-DAPT patients (P = 0.0049). DAPT patients received more transfusions of red blood cells [median 8 U (Q1-Q3 4-15) vs 5.5 U (2-11), P < 0.0001] and platelets [4 U (2-8) vs 2 U (1-4), P = 0.0001]. Crude 30-day mortality was 19.3% vs 17.0% (P = 0.60). After matching, major bleeding remained significantly more common in DAPT patients, 51.3% vs 39.3% [odds ratio (OR) 1.63, 95% confidence interval (CI) 1.05-2.51; P = 0.028], but mortality did not significantly differ (OR 0.88, 95% CI 0.51-1.50; P = 0.63). Major bleeding was associated with increased 30-day mortality (adjusted OR 2.44, 95% CI 1.72-3.46; P < 0.0001).DAPT prior to acute aortic dissection repair was associated with increased bleeding and transfusions but not with mortality. Major bleeding per se was associated with a significantly increased mortality. Correct diagnosis is important to avoid DAPT and thereby reduce bleeding risk, but ongoing DAPT should not delay surgery.

  • A single sequential snake saphenous vein graft versus separate left and right vein grafts in coronary artery bypass surgery: a population-based cohort study from the SWEDEHEART registry
  • 2019
  • Ingår i: European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery. - : Oxford University Press (OUP). - 1873-734X. ; 56:3, s. 518-525

    • Our goal was to compare short- and midterm outcomes after coronary artery bypass grafting (CABG) using 2 different revascularization strategies.A total of 6895 patients were included who had CABG in Sweden from 2009 to 2015 using the left internal mammary artery to the left anterior descending artery and either a single sequential saphenous vein graft connecting the left and right coronary territories to the aorta (snake graft, n = 2122) or separate vein grafts to both territories (n = 4773). Data were obtained from the Swedish Web System for Enhancement of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) and the Swedish Patient Registry. The groups were compared using adjusted logistic regression for short-term (30-day) and Cox regression and flexible parametric survival models for midterm outcomes. Primary outcome was a composite of all-cause mortality, myocardial infarction (MI), reangiography and new revascularization. The median follow-up time was 35 months.At 30 days, the incidences of the composite end point [odds ratio (OR) 1.31, 95% confidence interval (CI) 1.03-1.68; P = 0.03] and reangiography (OR 1.51, 95% CI 1.07-2.14; P = 0.02) were higher in the snake group. There was also a trend towards higher mortality (OR 1.47, 95% CI 0.97-2.22; P = 0.07). The event rates during the complete follow-up period were 6.5 (5.9-7.2) and 5.7 (5.3-6.1) per 100 person-years for the snake group and the separate vein group, respectively. At the midterm follow-up, no significant difference between the groups could be shown for the composite end point [hazard ratio (HR) 1.08, 95% CI 0.95-1.22; P = 0.24], mortality (HR 0.95, 95% CI 0.79-1.14; P = 0.56), MI (HR 1.11, 95% CI 0.88-1.41; P = 0.39) or new revascularization (HR 1.19, 95% CI 0.94-1.50; P = 0.15), whereas reangiography remained more common in the snake group (HR 1.25, 95% CI 1.05-1.48; P = 0.01).Snake grafts were associated with a higher rate of early postoperative complications, possibly reflecting a more demanding surgical technique, whereas midterm outcomes were comparable. Based on these data, one strategy cannot be recommended over the other.
