Abstract [en]

BACKGROUND: Registry-based randomized clinical trials have emerged as useful tools to provide evidence on the comparative efficacy and safety of different therapeutic strategies. However, it remains unknown whether the results of registry-based randomized clinical trials have a sizable impact on daily clinical practice. We sought, therefore, to describe the temporal trends in thrombus aspiration (TA) use in Sweden before, during, and after dissemination of the TASTE trial (Thrombus Aspiration in ST-Elevation Myocardial Infarction in Scandinavia) results.

METHODS AND RESULTS: From January 1, 2006, to December 31, 2017, we included all consecutive patients with ST-segment-elevation myocardial infarction undergoing percutaneous revascularization in Sweden. All patients were registered in the Swedish Coronary Angiography and Angioplasty Registry. A total of 55 809 ST-segment-elevation myocardial infarction patients were included. TA use in Sweden substantially decreased after dissemination of TASTE results (from 39.8% to 11.8% during and after TASTE, respectively). Substantial variability in TA use across treating centers was observed before TASTE (TA use ranging from 0% to 70%), but after TASTE both the interhospital variability and the frequency of TA use were markedly reduced. A constant shift in medical practice was seen about 4 months after dissemination of the TASTE trial results. Time trends for all-cause mortality and definite stent thrombosis at 30 days were not associated with variations in TA use (P values >0.05 using the Granger test).

CONCLUSIONS: In Sweden, the results of the TASTE trial were impactful in daily clinical practice and led to a relevant decrease in TA use in ST-segment-elevation myocardial infarction patients undergoing percutaneous revascularization.

Abstract [en]

BACKGROUND: Genetic variation at chromosome 9p21 is a recognized risk factor for coronary heart disease (CHD). However, its effect on disease progression and subsequent events is unclear, raising questions about its value for stratification of residual risk.

METHODS: A variant at chromosome 9p21 (rs1333049) was tested for association with subsequent events during follow-up in 103 357 Europeans with established CHD at baseline from the GENIUS-CHD (Genetics of Subsequent Coronary Heart Disease) Consortium (73.1% male, mean age 62.9 years). The primary outcome, subsequent CHD death or myocardial infarction (CHD death/myocardial infarction), occurred in 13 040 of the 93 115 participants with available outcome data. Effect estimates were compared with case/control risk obtained from the CARDIoGRAMplusC4D consortium (Coronary Artery Disease Genome-wide Replication and Meta-analysis [CARDIoGRAM] plus The Coronary Artery Disease [C4D] Genetics) including 47 222 CHD cases and 122 264 controls free of CHD.

RESULTS: Meta-analyses revealed no significant association between chromosome 9p21 and the primary outcome of CHD death/myocardial infarction among those with established CHD at baseline (GENIUSCHD odds ratio, 1.02; 95% CI, 0.99-1.05). This contrasted with a strong association in CARDIoGRAMPlusC4D odds ratio 1.20; 95% CI, 1.18-1.22; P for interaction < 0.001 compared with the GENIUS-CHD estimate. Similarly, no clear associations were identified for additional subsequent outcomes, including all-cause death, although we found a modest positive association between chromosome 9p21 and subsequent revascularization (odds ratio, 1.07; 95% CI, 1.04-1.09).

CONCLUSIONS: In contrast to studies comparing individuals with CHD to disease-free controls, we found no clear association between genetic variation at chromosome 9p21 and risk of subsequent acute CHD events when all individuals had CHD at baseline. However, the association with subsequent revascularization may support the postulated mechanism of chromosome 9p21 for promoting atheroma development.

Abstract [en]

Background: The aim of this study was to assess one-year outcomes of invasive and non-invasive strategies in ST-elevation myocardial infarction (STEMI) among multimorbid older people with complex health needs.

Methods: We included patients, registered between 2006 and 2013 in the SWEDEHEART registry, who were 70 years old or older with STEMI, had multimorbidily and complex health needs and were discharged alive. The one-year outcomes of patients who underwent invasive strategy (examined with coronary angiography <= 14 days) were compared to those who did not. The primary event was a composite of all-cause death, admission due to new acute coronary syndrome, stroke or transient ischemic attack.

Results: We identified patients, and 1089 were managed invasively and 570 non-invasively. The mean age was 79 years and 83 years in the 2 groups, respectively. After multivariable adjustment for baseline differences between the groups, including propensity scores, the primary event occurred in 31% of patients in the invasive group and 55% in the non-invasive group, adjusted hazard ratio (95% confidence intervals): 0.67 (0.54-0.83). One-year mortality was 18% in the invasive group and 45% in the non-invasive group, adjusted hazard ratio 0.51 (0.39-0.65).

Conclusions: Multimorbid older people with complex health needs and STEMI had high rates of new ischemic events and death. In this cohort of older, high risk STEMI patients, an invasive strategy was associated with lower event rates. Randomized studies are needed to clarify whether these high risk patients who might benefit from invasive care are being managed too conservatively.

Abstract [en]

BACKGROUND: The Genetics of Subsequent Coronary Heart Disease (GENIUS-CHD) consortium was established to facilitate discovery and validation of genetic variants and biomarkers for risk of subsequent CHD events, in individuals with established CHD.

METHODS: The consortium currently includes 57 studies from 18 countries, recruiting 185 614 participants with either acute coronary syndrome, stable CHD, or a mixture of both at baseline. All studies collected biological samples and followed-up study participants prospectively for subsequent events.

RESULTS: Enrollment into the individual studies took place between 1985 to present day with a duration of follow-up ranging from 9 months to 15 years. Within each study, participants with CHD are predominantly of self-reported European descent (38%-100%), mostly male (44%-91%) with mean ages at recruitment ranging from 40 to 75 years. Initial feasibility analyses, using a federated analysis approach, yielded expected associations between age (hazard ratio, 1.15; 95% CI, 1.14-1.16) per 5-year increase, male sex (hazard ratio, 1.17; 95% CI, 1.13-1.21) and smoking (hazard ratio, 1.43; 95% CI, 1.35-1.51) with risk of subsequent CHD death or myocardial infarction and differing associations with other individual and composite cardiovascular endpoints.

CONCLUSIONS: GENIUS-CHD is a global collaboration seeking to elucidate genetic and nongenetic determinants of subsequent event risk in individuals with established CHD, to improve residual risk prediction and identify novel drug targets for secondary prevention. Initial analyses demonstrate the feasibility and reliability of a federated analysis approach. The consortium now plans to initiate and test novel hypotheses as well as supporting replication and validation analyses for other investigators.

Abstract [en]

Background: To assess the relationship between radiation doses to the coronary arteries (CAs) and location of a coronary stenosis that required intervention after three-dimensional conformal radiotherapy (3DCRT) for breast cancer (BC).

Methods: The study population consisted of 182 women treated for BC in Sweden between 1992 and 2012. All women received 3DCRT and subsequently underwent coronary angiography due to a suspected coronary event. CA segments were delineated in the patient's original planning-CT and radiation doses were recalculated based on the dose distribution of the original radiotherapy (RT) plan. The location of the CA stenosis that required intervention was identified from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Logistic regression analysis was used to assess the relationship between CA radiation doses and risk of a later coronary intervention at this specific location.

Results: The odds ratio (OR) varied by radiation dose to the mid left anterior descending artery (LAD) (p=0.005). Women receiving mean doses of 1-5 Gray (Gy) to the mid LAD had an adjusted OR of 0.90 (95% CI 0.47-1.74) for a later coronary intervention compared to women receiving mean doses of 0-1Gy to the mid LAD. In women receiving mean doses of 5-20Gy to the mid LAD, an adjusted OR of 1.24 (95% CI 0.52-2.95) was observed, which increased to an OR of 5.23 (95% CI 2.01-13.6) for mean doses over 20Gy, when compared to women receiving mean doses of 0-1Gy to the mid LAD.

Conclusions: In women receiving conventional 3DCRT for BC between 1992 and 2012, radiation doses to the LAD remained high and were associated with an increased requirement of coronary intervention in mid LAD. The results support that the LAD radiation dose should be considered in RT treatment planning and that the dose should be kept as low as possible. Minimising the dose to LAD is expected to diminish the risk of later radiation-induced stenosis.

Abstract [en]

AIMS: To elucidate the short and long-term outcome of patients treated with covered stents compared to all other stented patients. Covered stents are mostly used for coronary perforations with high risk of early adverse events, but their long-term outcome are unknown.

METHODS AND RESULTS: The Swedish national registries from 2005 - 2017 disclosed 265 patients receiving 366 covered stents. Their outcomes were compared to all other 197 948 stented patients receiving 320 784 stents. Compared to regular stents, significant differences (p<0.001) between covered stents in short and long-term in respect to in-stent restenosis (ISR); target lesion revascularization (TLR); re-infarction (MI), Re-PCI and mortality, were all higher. The higher mortality was concentrated within the first month, as a landmark analysis at that time-point adjusted for age and procedural indication demonstrated no future difference in mortality, HR 1.02 (0.78-1.33) p=0.877. Stent thrombosis (ST) within one year were reported higher in covered stents than in other stents. However, no ST was reported in equine pericardial covered stents.

CONCLUSIONS: This observational study including the entire Swedish population shows patients receiving a covered stents have a significantly higher risk of all adverse events. Reassuring, long-term the mortality appears to be similar to other stented patients.

Abstract [en]

AIMS: The clinical performance of the SYNERGY drug-eluting stent (DES) in patients with acute myocardial infarction (MI) has not been investigated in detail. We sought to report on the outcomes after SYNERGY DES (Boston Scientific, Marlborough, MA, USA) implantation in patients with MI undergoing percutaneous revascularisation (PCI).

METHODS AND RESULTS: We included all consecutive patients with MI undergoing PCI with the SYNERGY DES and newer-generation DES (n-DES group) in Sweden. From March 2013 to September 2016, a total of 36,292 patients, of whom 39.7% presented with ST-elevation MI, were included. As compared to patients in the n-DES group (n=31,403), patients in the SYNERGY group (n=4,889) were older and presented more often with left main or three-vessel disease involvement, as well as with restenotic lesions (p<0.001 for all parameters). The Kaplan-Meier estimates of ST at two years in the SYNERGY and n-DES groups were 0.69% and 0.81%, respectively (adjusted HR 1.00, 95% CI: 0.69-1.46; p=0.99). Clinically relevant restenosis was encountered in 1.48% and 1.25% of patients in the SYNERGY and n-DES groups, respectively (adjusted HR 1.05, 95% CI: 0.81-1.37; p=0.72). No differences in the risk of all-cause death and recurrent MI were found between the two groups after adjustment (adjusted HR 1.12, 95% CI: 0.98-1.28; p=0.10, and adjusted HR 0.95, 95% CI: 0.82-1.10; p=0.49, respectively).

CONCLUSIONS: In a large and unselected cohort of patients with MI undergoing percutaneous revascularisation with the SYNERGY DES, stent performance and clinical outcomes did not differ compared with other n-DES up to two years.

Abstract [en]

OBJECTIVE: To describe sex aspects on extent of coronary artery disease (CAD) and prognosis in a contemporary population with type 1 diabetes.

RESEARCH DESIGN AND METHODS: All patients undergoing coronary angiography, 2001-2013, included in the Swedish Coronary Angiography and Angioplasty Registry and the Swedish National Diabetes Register as type 1 diabetes were followed for mortality until 31 December 2013. The coronary angiogram was classified into normal, one-vessel disease, two-vessel disease, three-vessel disease, and left main stem disease.

RESULTS: In all, 2,776 patients (42% women) with mean age 58 years (SD 11) were followed for 7.2 years (SD 2.2). Diabetes duration was longer in women (37 14 vs. 34 +/- 14 years in men; P < 0.001), who also had more retinopathy (68% vs. 65%; P = 0.050), whereas microalbuminuria was less common (41% vs. 51%; P < 0.001). Indications for coronary angiography did not substantially differ in women and men. The extent of CAD was somewhat less severe in women (normal angiogram 23.5% vs. 19.1%, three-vessel and left main stem disease 34.5% vs. 40.4%; P = 0.002), whereas mortality did not differ (adjusted hazard ratio 1.03 [95% CI 0.88-1.20]; P = 0.754). The standard mortality ratio for women the first year was 7.49 (5.73-9.62) and for men was 4.58 (3.60-5.74).

CONCLUSIONS: In patients with type 1 diabetes admitted for coronary angiography, the extent of CAD was almost similar in women and men, and total long-term mortality did not differ. Type 1 diabetes was associated with higher mortality risk in women than in men when compared with the general population. These data support that type 1 diabetes attenuates the cardiovascular risk difference seen in men and women in the general population.

Abstract [en]

Aims Preliminary studies suggest that direct stenting (DS) during percutaneous coronary intervention (PCI) may reduce microvascular obstruction and improve clinical outcome. Thrombus aspiration may facilitate DS. We assessed the impact of DS on clinical outcome and myocardial reperfusion and its interaction with thrombus aspiration among ST-segment elevation myocardial infarction (STEMI) patients undergoing PCI. Methods and results Patient-level data from the three largest randomized trials on routine manual thrombus aspiration vs. PCI only were merged. A 1:1 propensity matched population was created to compare DS and conventional stenting. Synergy between DS and thrombus aspiration was assessed with interaction P-values in the final models. In the unmatched population (n= 17329), 32% underwent DS and 68% underwent conventional stenting. Direct stenting rates were higher in patients randomized to thrombus aspiration as compared with PCI only (41% vs. 22%; P < 0.001). Patients undergoing DS required less contrast (162 mL vs. 172 mL; P < 0.001) and had shorter fluoroscopy time (11.1 min vs. 13.3 min; P < 0.001). After propensity matching (n = 10944), no significant differences were seen between DS and conventional stenting with respect to 30-day cardiovascular death [1.7% vs. 1.9%; hazard ratio 0.88, 95% confidence interval (CI) 0.55-1.41; P=0.60; P-interaction = 0.96) and 30-day stroke or transient ischaemic attack (0.6% vs. 0.4%; odds ratio 1.02; 95% CI 0.14-7.54; P= 0.99; P-interaction = 0.81). One-year results were similar. No significant differences were seen in electrocardiographic and angiographic myocardial reperfusion measures. Conclusion Direct stenting rates were higher in patients randomized to thrombus aspiration. Clinical outcomes and myocardial reperfusion measures did not differ significantly between DS and conventional stenting and there was no interaction with thrombus aspiration.

Abstract [en]

Background-Long-term disease progression after myocardial infarction (MI) is inadequately understood. We evaluated the pattern and angiographic properties (culprit lesion [CL]/non-CL [NCL]) of recurrent MI (re-MI) in a large real-world patient population. Methods and Results-Our observational study used prospectively collected data in 108 615 patients with first-occurrence MI enrolled in the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) between July 1, 2006 and November 29, 2014. During follow-up (median, 3.2 years), recurrent hospitalization for MI occurred in 11 117 patients (10.2%). Of the patients who underwent coronary angiography for the index MI, a CL was identified in 44 332 patients. Of those patients, 3464 experienced an re-MI; the infarct originated from the NCL in 1243 patients and from the CL in 655 patients. In total, 1566 re-MIs were indeterminate events and could not be classified as NCL or CL re-MIs. The risk of re-MI within 8 years related to the NCL was 0.06 (95% confidence interval [CI], 0.05-0.06), compared with 0.03 (95% CI, 0.02-0.03) for the CL. There were no large differences in baseline characteristics of patients with subsequent NCL versus CL re-MIs. Independent predictors of NCL versus CL re-MI were multivessel disease (odds ratio, 2.29; 95% CI, 1.87-2.82), male sex (odds ratio, 1.36; 95% CI, 1.09-1.71), and a prolonged time between the index and re-MI (odds ratio, 1.16; 95% CI, 1.10-1.22). Conclusions-In a large cohort of patients with first-occurrence MI undergoing percutaneous coronary intervention, the risk of re-MI originating from a previously untreated lesion was twice higher than the risk of lesions originating from a previously stented lesion.
