  • Long-Term Outcome of Mustard/Senning Correction for Transposition of the Great Arteries in Sweden and Denmark
  • 2015
  • Ingår i: Circulation. - : American Heart Association. - 0009-7322 .- 1524-4539. ; 132:8, s. 633-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The atrial switch operation, the Mustard or Senning operation, for the transposition of the great arteries (TGA) was introduced in the late 1950s and was the preferred surgery for TGA until the early 1990s. The Mustard and Senning operation involves extensive surgery in the atria and leaves the right ventricle as the systemic ventricle. The Mustard and Senning cohort is now well into adulthood and we begin to see the long-term outcome. METHODS AND RESULTS: All the 6 surgical centers that performed Mustard and Senning operations in Sweden and Denmark identified all operated TGA patients. Information about death was obtained in late 2007 and early 2008 from the Danish and Swedish Centralised Civil Register by using the patients' unique national Civil Registration Numbers. Four hundred sixty-eight patients undergoing the atrial switch operation were identified. Perioperative 30-day mortality was 20%, and 60% were alive after 30 years of follow-up. Perioperative mortality was significantly increased by the presence of a ventricular septal defect, left ventricular outflow obstruction, surgery early in the Mustard and Senning era. However, only pacemaker implantation is predictive of long-term outcome (hazard ratio, 1.90; 95% confidence interval, 1.05-3.46, P=0.04), once the TGA patient has survived the perioperative period. The risk of reoperation was correlated to the presence of associated defects and where the first Mustard/Senning operation was performed. CONCLUSIONS: The long-term survival of patients with Mustard and Senning correction for TGA appears to be primarily determined by factors in the right ventricle and tricuspid valve and not the timing of or the type of surgery in childhood. Cardiac function necessitating the implantation of a pacemaker is associated with an increase in mortality.

  • Sub-acute cardiac magnetic resonance to predict irreversible reduction in left ventricular ejection fraction after ST-segment elevation myocardial infarction : A DANAMI-3 sub-study
  • Ingår i: International Journal of Cardiology. - : Elsevier. - 0167-5273. ; 301, s. 215-219
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To predict irreversible reduction in left ventricular ejection fraction (LVEF) during admission for ST-segment elevation myocardial infarction (STEMI) using cardiac magnetic resonance (CMR) in addition to classical clinical parameters. Irreversible reduction in LVEF is an important prognostic factor after STEMI which necessitates medical therapy and implantation of prophylactic implantable cardioverter defibrillator (ICD). Methods and results: A post-hoc analysis of DANAMI-3 trial program (Third DANish Study of Optimal Acute Treatment of Patients With ST-elevation Myocardial Infarction) which recruited 649 patients who had CMR performed during index hospitalization and after 3 months. Patients were divided into two groups according to CMR-LVEF at 3 months: Group 1 with LVEF≤35% and Group 2 with LVEF>35%. Group 1 included 15 patients (2.3%) while Group 2 included 634 patients (97.7%). A multivariate analysis showed that: Killip class >1 (OR 7.39; CI:1.47–36.21, P = 0.01), symptom onset-to-wire ≥6 h (OR 7.19; CI 1.07–50.91, P = 0.04), LVEF≤35% using index echocardiography (OR 7.11; CI: 1.27–47.43, P = 0.03), and infarct size ≥40% of LV on index CMR (OR 42.62; CI:7.83–328.29, P < 0.001) independently correlated with a final LVEF≤35%. Clinical models consisted of these parameters could identify 7 out of 15 patients in Group 1 with 100% positive predictive value. Conclusion: Together with other clinical measurements, the assessment of infarct size using late Gadolinium enhancement by CMR during hospitalization is a strong predictor of irreversible reduction in CMR_LVEF ≤35. That could potentially, after validation with future research, aids the selection and treatment of high-risk patients after STEMI, including implantation of prophylactic ICD during index hospitalization.

  • Prevalence of heart failure and other risk factors among first-degree relatives of women with peripartum cardiomyopathy
  • 2019
  • Ingår i: Heart. - : BMJ Publishing Group. - 1355-6037. ; 105:14, s. 1057-1062
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Peripartum cardiomyopathy (PPCM) is a rare disease carrying a risk of death and chronic heart failure.It is unknown if women with PPCM have a family history of heart failure. We investigated the prevalence of heart failure and hypertension in first-degree relatives to women with PPCM. Methods: A cohort of 61 women with PPCM was identified through the nationwide Danish registers from 2005 to 2014, and each individual diagnosis of PPCM was validated through review of patient records. We excluded 13 women due to lack of data on relatives. In a case-control design, the 48 remaining women were matched (on age, year of childbirth, parity and number of siblings) to 477 birth-giving Danish women without heart failure. We obtained information on first-degree relatives (parents and siblings) through the National Danish Registers. Results: The cohort of 48 women with PPCM had a mean age of 31 years (SD 6). The prevalence of heart failure in any first-degree relative was higher in women with PPCM, compared with controls (23% vs 10%, p=0.011). A first-degree relative with any cardiovascular diagnosis was not more frequent in women with PPCM versus controls (77% vs 70%, p=0.280), but for siblings only, any cardiovascular diagnosis was more frequent in siblings to women with PPCM (29% vs 16%, p=0.026). Conclusion: Having a first-degree relative with heart failure was significantly more frequent in a cohort of validated PPCM cases than in controls, supporting the notion of shared aetiology between PPCM and other forms of heart failure.

  • Impact of Multiple Myocardial Scars Detected by CMR in Patients Following STEMI
  • 2019
  • Ingår i: JACC: Cardiovascular Imaging. - : Elsevier. - 1936-878X. ; 12:11P1, s. 2168-2178
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: This study investigated the incidence and long-term prognostic importance of multiple myocardial scars in cardiac magnetic resonance (CMR) in a large contemporary cohort of patients with ST-segment elevation myocardial infarction (STEMI). Background: Patients presenting with STEMI may have multiple infarctions/scars caused by multiple culprit lesions, previous myocardial infarction (MI) or procedure-related MI due to nonculprit interventions. However, the incidence, long-term prognosis, and distribution of causes of multiple myocardial scars remain unknown. Methods: CMR was performed in 704 patients with STEMI 1 day after primary percutaneous coronary intervention (PCI) and again 3 months later. Myocardial scars were assessed by late gadolinium enhancement (LGE). T2-weighted technique was used to differentiate acute from chronic infarctions. The presence of multiple scars was defined as scars located in different coronary territories. The combined endpoints of all-cause mortality and hospitalization for heart failure were assessed at 39 months (interquartile range [IQR]: 31 to 48 months). Results: At 3 months, 59 patients (8.4%) had multiple scars. Of these, multiple culprits in STEMI were detected in 7 patients (1%), and development of a second nonculprit scar at follow-up occurred in 10 patients (1.4%). The most frequent cause of multiple scars was a chronic scar in the nonculprit myocardium. The presence of multiple scars was independently associated with an increased risk of all-cause mortality and hospitalization for heart failure (hazard ratio: 2.7; 95% confidence interval: 1.1 to 6.8; p = 0.037). Conclusions: Multiple scars were present in 8.4% of patients with STEMI and were independently associated with an increased risk of long-term morbidity and mortality. The presence of multiple myocardial scars on CMR may serve as a useful tool in risk stratification of patients following STEMI.

  • Danegaptide for primary percutaneous coronary intervention in acute myocardial infarction patients : A phase 2 randomised clinical trial
  • Ingår i: Heart. - : BMJ Publishing Group. - 1355-6037. ; 104:19, s. 1593-1599
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Reperfusion immediately after reopening of the infarct-related artery in ST-segment elevation myocardial infarction (STEMI) may cause myocardial damage in addition to the ischaemic insult (reperfusion injury). The gap junction modulating peptide danegaptide has in animal models reduced this injury. We evaluated the effect of danegaptide on myocardial salvage in patients with STEMI. Methods: In addition to primary percutaneous coronary intervention in STEMI patients with thrombolysis in myocardial infarction flow 0-1, single vessel disease and ischaemia time less than 6 hours, we tested, in a clinical proof-of-concept study, the therapeutic potential of danegaptide at two-dose levels. Primary outcome was myocardial salvage evaluated by cardiac MRI after 3 months. Results: From November 2013 to August 2015, a total of 585 patients were randomly enrolled in the trial. Imaging criteria were fulfilled for 79 (high dose), 80 (low dose) and 84 (placebo) patients eligible for the per-protocol analysis. Danegaptide did not affect the myocardial salvage index (danegaptide high (63.9±14.9), danegaptide low (65.6±15.6) and control (66.7±11.7), P=0.40), final infarct size (danegaptide high (19.6±11.4 g), danegaptide low (18.6±9.6 g) and control (21.4±15.0 g), P=0.88) or left ventricular ejection fraction (danegaptide high (53.9%±9.5%), danegaptide low (52.7%±10.3%) and control (52.1%±10.9%), P=0.64). There was no difference between groups with regard to clinical outcome. Conclusions: Administration of danegaptide to patients with STEMI did not improve myocardial salvage. Trial registration number: NCT01977755; Pre-results.

  • Isolated pulmonary regurgitation causes decreased right ventricular longitudinal function and compensatory increased septal pumping in a porcine model
  • Ingår i: Acta Physiologica. - : Wiley-Blackwell. - 1748-1716. ; 221:3, s. 163-173
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: Longitudinal ventricular contraction is a parameter of cardiac performance with predictive power. Right ventricular (RV) longitudinal function is impaired in patients with free pulmonary regurgitation (PR) following corrective surgery for Tetralogy of Fallot (TOF). It remains unclear whether this is a consequence of the surgical repair, or whether it is inherent to PR. The aim of this study was to assess the relationship between longitudinal, lateral and septal pumping in a porcine model of isolated PR. Methods: Piglets were divided into a control (n = 8) group and a treatment (n = 12) group, which received a stent in the pulmonary valve orifice, inducing PR. After 2-3 months, animals were subjected to cardiac magnetic resonance imaging. A subset of animals (n = 6) then underwent percutaneous pulmonary valve replacement (PPVR) with follow-up 1 month later. Longitudinal, lateral and septal contributions to stroke volume (SV) were quantified by measuring volumetric displacements from end-diastole to end-systole in the cardiac short axis and long axis. Results: PR resulted in a lower longitudinal contribution to RV stroke volume, compared to controls (60.0 ± 2.6% vs. 73.6 ± 3.8%; P = 0.012). Furthermore, a compensatory increase in septal contribution to RVSV was observed (11.0 ± 1.6% vs. -3.1 ± 1.5%; P < 0.0001). The left ventricle (LV) showed counter-regulation with an increased longitudinal LVSV. Changes in RV longitudinal function were reversed by PPVR. Conclusion: These findings suggest that PR contributes to decreased RV longitudinal function in the absence of scarring from cardiac surgery. Measurement of longitudinal RVSV may aid risk stratification and timing for interventional correction of PR in TOF patients.

  • Complete Revascularization Versus Culprit Lesion Only in Patients With ST-Segment Elevation Myocardial Infarction and Multivessel Disease : A DANAMI-3–PRIMULTI Cardiac Magnetic Resonance Substudy
  • Ingår i: JACC: Cardiovascular Interventions. - : Elsevier. - 1936-8798. ; 12:8, s. 721-730
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The aim of this study was to evaluate the effect of fractional flow reserve (FFR)–guided revascularization compared with culprit-only percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) on infarct size, left ventricular (LV), function, LV remodeling, and the presence of nonculprit infarctions. Background: Patients with STEMI with multivessel disease might have improved clinical outcomes after complete revascularization compared with PCI of the infarct-related artery only, but the impact on infarct size, LV function, and remodeling as well as the risk for periprocedural infarction are unknown. Methods: In this substudy of the DANAMI-3 (Third Danish Trial in Acute Myocardial Infarction)–PRIMULTI (Primary PCI in Patients With ST-Elevation Myocardial Infarction and Multivessel Disease: Treatment of Culprit Lesion Only or Complete Revascularization) randomized trial, patients with STEMI with multivessel disease were randomized to receive either complete FFR-guided revascularization or PCI of the culprit vessel only. The patients underwent cardiac magnetic resonance imaging during index admission and at 3-month follow-up. Results: A total of 280 patients (136 patients with infarct-related and 144 with complete FFR-guided revascularization) were included. There were no differences in final infarct size (median 12% [interquartile range: 5% to 19%] vs. 11% [interquartile range: 4% to 18%]; p = 0.62), myocardial salvage index (median 0.71 [interquartile range: 0.54 to 0.89] vs. 0.66 [interquartile range: 0.55 to 0.87]; p = 0.49), LV ejection fraction (mean 58 ± 9% vs. 59 ± 9%; p = 0.39), and LV end-systolic volume remodeling (mean 7 ± 22 ml vs. 7 ± 19 ml; p = 0.63). New nonculprit infarction occurring after the nonculprit intervention was numerically more frequent among patients treated with complete revascularization (6 [4.5%] vs. 1 [0.8%]; p = 0.12). Conclusions: Complete FFR-guided revascularization in patients with STEMI and multivessel disease did not affect final infarct size, LV function, or remodeling compared with culprit-only PCI.

  • Usefulness of High Sensitivity Troponin T to Predict Long-Term Left Ventricular Dysfunction After ST-Elevation Myocardial Infarction
  • 2020
  • Ingår i: American Journal of Cardiology. - : Excerpta Medica. - 0002-9149.
  • Tidskriftsartikel (refereegranskat)abstract
    • Guidelines recommend the use of transthoracic echocardiography (TTE) and clinical scores to risk stratify patients after ST-elevation myocardial infarction (STEMI). High sensitivity troponin T (hs-cTnT) is predictive of outcome after STEMI but the predictive value of hs-cTnT relative to other risk assessment tools has not been established. We aimed to compare the predictive value of hs-cTnT to other risk assessment tools in patients with STEMI. A subset of 578 patients with STEMI were included in this post-hoc study from the Third DANish Study of Optimal Acute Treatment of Patients with ST-segment Elevation Myocardial Infarction trial. Patients underwent cardiac magnetic resonance imaging (CMR) during index hospitalization as well as TTE at 1 year after their STEMI. The predictive value of hs-cTnT was compared with CKMB, infarct size (IS)/left ventricular ejection fraction (LVEF) assessed with CMR, LVEF assessed at discharge with TTE and the Global Registry of Acute Coronary Events (GRACE) and Thrombolysis in Myocardial Infarction (TIMI) risk-scores. The primary outcome was LV systolic dysfunction defined as LVEF ≤40% after 1 year on TTE. The area under the receiver operating characteristic curve analyses showed no significant difference between hs-cTnT and early CMR-assessed IS or LVEF in predicting subsequent LVEF ≤40%. Area under the curve for hs-cTnT was 0.82, 0.85 for IS (p = 0.22), and 0.87 for LVEF (p = 0.23). For predischarge TTE-assessed LVEF, the value was 0.85 (p = 0.45), 0.63 for creatine kinase-MB (p <0.001), 0.61 for the GRACE score (p <0.001), and 0.70 for the TIMI score (p = 0.02). A peak hs-cTnT value <3,500 ng/L ruled out LVEF ≤40% with probability of 98%. In conclusion, in patients presenting with STEMI undergoing PCI, hs-cTnT level strongly predicted long-term LV dysfunction and could be used as a clinical risk stratification tool to identify patients at high risk of progressing to LV dysfunction due to its general availability and high-predictive accuracy.

  • Benefit From Reperfusion With Primary Percutaneous Coronary Intervention Beyond 12 Hours of Symptom Duration in Patients With ST-Segment-Elevation Myocardial Infarction
  • 2018
  • Ingår i: Circulation. Cardiovascular Interventions. - : American Heart Association. - 1941-7632. ; 11:9, s. 006842-006842
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Guidelines recommend primary percutaneous coronary intervention (PCI) in patients with ST-segment-elevation myocardial infarction (STEMI) presenting ≥12 hours of symptom onset in the presence of ongoing ischemia. However, data supporting this recommendation are limited. We evaluated the effect of primary PCI on reperfusion success, using cardiac magnetic resonance, in STEMI patients with signs of ongoing ischemia presenting 12 to 72 hours after symptom onset compared with STEMI patients presenting <12 hours.METHODS AND RESULTS: We included 865 STEMI patients who underwent cardiac magnetic resonance just after index PCI and 3 months later. Despite equal area at risk (34±12% versus 33±12%; P=0.370), patients presenting late (n=58) had larger final infarct size (13% [interquartile range, 9-24] versus 11% [interquartile range, 4-19]; P=0.037) and smaller myocardial salvage index (0.58 [interquartile range, 0.39-0.71] versus 0.65 [interquartile range, 0.49-0.84]; P=0.021) compared with patients presenting <12 hours after symptom onset (n=807). However, 65% of late-presenting patients achieved substantial myocardial salvage ≥0.50, and area under the curve for symptom onset to PCI as predictor of a myocardial salvage index ≥0.50 was poor (0.58 [95% CI, 0.53-0.63]; P<0.001). In addition, final infarct size, salvage index and left ventricular function correlated weakly with duration from symptom onset to primary PCI ( R2 values <0.05).CONCLUSIONS: STEMI patients with signs of ongoing ischemia treated with primary PCI 12 to 72 hours after symptom onset had less myocardial salvage and developed larger infarcts. However, a large proportion achieved substantial myocardial salvage indicating a benefit from primary PCI in late-presenting patients.CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov .
