    • Aims The FRISC II trial demonstrated that, for patients with unstable coronary artery disease, an early invasive strategy following acute treatment with dalteparin and aspirin, was superior to a more conservative approach. We evaluated whether it is beneficial to extend treatment with dalteparin to patients eligible for revascularization but for whom these procedures are performed after the initial hospital stay. Methods and Results As a subanalysis of FRISC II, the efficacy and clinical safety of extended dalteparin treatment (5000 or 7500 IU. 12 h-1 to day 90) compared with placebo was assessed in 1601 patients randomized to a non-invasive group who underwent revascularization only when necessary because of recurring symptoms, (re)infarction, or severe ischaemia. By day 90, 440 patients had undergone revascularization: 267 of these procedures occurred during the double-blind period. All patients initially received acute treatment (5-7 days from day 1) with dalteparin (120 IU / kg-1 12 h-1). The incidence of death and/or myocardial infarction was monitored until revascularization or day 45 and until revascularization or day 90. There was a significant difference in the estimated probability of death and/or myocardial infarction until revascularization or day 90 in favour of dalteparin (log-rank test, P=0╖0415) and there was a significant reduction in death and/or myocardial infarction in favour of extended dalteparin treatment at day 45, with a 57% relative risk reduction (P=0╖0004). At day 90 the relative risk reduction was 29%. The safety profile of extended dalteparin treatment was similar to that of acute usage. Conclusion Extended dalteparin treatment for up to 45 days is effective and safe as a bridging therapy for patients with unstable coronary artery disease awaiting revascularization. ⌐ 2002 The European Society of Cardiology.

  • A long-term perspective on the protective effects of an early invasive strategy in unstable coronary artery disease : Two-year follow-up of the FRISC-II Invasive Study
  • 2002
  • Ingår i: Journal of the American College of Cardiology. - 0735-1097 .- 1558-3597. ; 40:11, s. 1902-1914
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: We sought to report the first and repeat events and to separate spontaneous and procedure-related events over two years in the Fast Revascularization during InStability in Coronary artery disease (FRISC-II) invasive trial. BACKGROUND: The FRISC-II invasive trial compared the long-term effects of an early invasive versus noninvasive strategy, in terms of death and myocardial infarction (MI) and the need for repeat hospital admissions and late revascularization procedures in patients with coronary artery disease (UCAD). METHODS: In the FRISC-II trial, 2,457 patients with UCAD were randomized to an early invasive or noninvasive strategy. RESULTS: At 24 month follow-up, there were reductions in mortality (n = 45 [3.7%] vs. 67 [5.4%], risk ratio 0.68 [95% confidence interval (CI) 0.47 to 0.98], p = 0.038), MI (n = 111 [9.2%] vs. 156 [12.7%], risk ratio 0.72 [95% CI 0.57 to 0.91], p = 0.005), and the composite end point of death or MI (n = 146 [12.1%] vs. 200 [16.3%], risk ratio 0.74 [95% CI 0.61 to 0.90], p = 0.003) in the invasive compared with the noninvasive group. Procedure-related MIs were two to three times more common, but spontaneous ones were three times less common in the invasive than in the noninvasive group. After the first year, there was no difference in mortality (n = 20 [1.7%]) between the two groups and fewer MIs in the invasive group (p = 0.031). CONCLUSIONS: In UCAD, the early invasive approach leads to a sustained reduction in mortality, cardiac morbidity, and the need for repeat hospital admissions and late revascularization procedures. Although the benefits are greatest during the first months, during the second year, cardiac morbidity is lower and the need for hospital care is less in the invasive group. © 2002 by the American College of Cardiology Foundation.

  • FRISC score for selection of patients for an early invasive treatment strategy in unstable coronary artery disease
  • 2005
  • Ingår i: Heart. - : BMJ. - 1355-6037 .- 1468-201X. ; 91:8, s. 1047-1052
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To develop a scoring system for risk stratification and evaluation of the effect of an early invasive strategy for treatment of unstable coronary artery disease (CAD). Design: Retrospective analysis of a randomised study (FRISC II; fast revascularisation in instability in coronary disease). Setting: 58 Scandinavian hospitals. Patients: 2457 patients with unstable CAD from the FRISC II study. Main outcome measures: One year rates of mortality and death/myocardial infarction (MI). Methods: Patients were randomly assigned to an early invasive or a non-invasive strategy. From the non-invasive cohort independent variables of death or death/MI were identified. Results: Seven factors, age > 70 years, male sex, diabetes, previous MI, ST depression, and increased concentrations of troponins and markers of inflammation (interleukin 6 or C reactive protein), were associated with an independent increased risk for death or death/MI. In patients with ≥ 5 of these factors the invasive strategy reduced mortality from 15.4% (20 of 130) to 5.2% (7 of 134) (risk ratio (RR) 0.34, 95% confidence interval (CI) 0.15 to 0.78, p  =  0.006). Death/MI was also reduced in patients with 3–4 factors from 15.7% (80 of 511) to 10.8% (58 of 538) (RR 0.69, 95% CI 0.50 to 0.94, p  =  0.02). Neither death nor death/MI was reduced in patients with 0–2 risk factors. Conclusion: In unstable CAD, this scoring system based on factors independently associated with an adverse outcome can be used shortly after admission to the hospital for risk stratification and for selection of patients to an early invasive treatment strategy.

  • Is early invasive treatment of unstable coronary artery disease equally effective for both women and men?
  • 2001
  • Ingår i: Journal of the American College of Cardiology. - 0735-1097 .- 1558-3597. ; 38:1, s. 41-48
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The Fragmin and fast Revascularization during InStability in Coronary artery disease (FRISC II) trial compared the effectiveness of an early invasive versus a noninvasive strategy in terms of the incidence of death and myocardial infarction (MI) in patients with unstable coronary artery disease (CAD). OBJECTIVES: In this subanalysis, we sought to evaluate gender differences in the effect of these different strategies. METHODS: The patients (749 women and 1,708 men) were randomized to early invasive or noninvasive strategies. Coronary angiography was performed within the first 7 days in 96% and 10% of the invasive and noninvasive groups, respectively, and revascularization was performed within the first 10 days in 71% and 9% of the invasive and noninvasive groups, respectively. RESULTS: Women presenting with unstable CAD were older, but fewer had previous infarctions, left ventricular dysfunction and elevated troponin T levels. Women had fewer angiographic changes. There was no difference in MI or death at 12 months among women in the invasive and noninvasive groups (12.4% vs. 10.5%, respectively), in contrast to the favorable effect in the invasively treated group of men (9.6% vs. 15.8%, p < 0.001). In an interaction analysis, there was a different effect of the early invasive strategy for the two genders (p = 0.008). CONCLUSIONS: Women with symptoms and/or signs of unstable CAD are older, but still have less severe CAD and a better prognosis compared with men. In contrast to its beneficial effect in men, an early invasive strategy did not reduce the risk of future events among women. Further research is warranted to identify the most appropriate treatment strategy in women with unstable CAD. ⌐ 2001 American College of Cardiology.
