    • Background-There are limited data on how the combination of diabetes mellitus (DM) and chronic kidney disease (CKD) affects cardiovascular outcomes as well as response to different P2Y(12) receptor antagonists, which represented the aim of the present investigation. Methods and Results-In this post hoc analysis of the PLATO (Platelet Inhibition and Patient Outcomes) trial, which randomized acute coronary syndrome patients to ticagrelor versus clopidogrel, patients (n=15 108) with available DM and CKD status were classified into 4 groups: DM+/CKD+ (n=1058), DM+/CKD- (n=2748), DM-/CKD+ (n=2160), and DM-/CKD- (n=9142). The primary efficacy end point was a composite of cardiovascular death, myocardial infarction, or stroke at 12 months. The primary safety end point was PLATO major bleeding. DM+/CKD+ patients had a higher incidence of the primary end point compared with DM-/CKD- patients (23.3% versus 7.1%; adjusted hazard ratio 2.22; 95% CI 1.88-2.63; P<0.001). Patients with DM+/CKD- and DM-/CKD+ had an intermediate risk profile. The same trend was shown for the individual components of the primary end point and for major bleeding. Compared with clopidogrel, ticagrelor reduced the incidence of the primary end point consistently across subgroups (P-interaction=0.264), but with an increased absolute risk reduction in DM+/CKD+. The effects on major bleeding were also consistent across subgroups (P-interaction=0.288). Conclusions-In acute coronary syndrome patients, a gradient of risk was observed according to the presence or absence of DM and CKD, with patients having both risk factors at the highest risk. Although the ischemic benefit of ticagrelor over clopidogrel was consistent in all subgroups, the absolute risk reduction was greatest in patients with both DM and CKD.

  • The efficacy of ticagrelor is maintained in women with acute coronary syndromes participating in the prospective, randomized, PLATelet inhibition and patient Outcomes (PLATO) trial
  • 2014
  • Ingår i: European Heart Journal. - 0195-668X .- 1522-9645. ; 35:23, s. 1541-1550

    • Aims The aim of this study was to assess the relationship between sex and clinical outcomes and treatment-related complications in patients with ST-elevation or non-ST-elevation acute coronary syndromes (ACS) randomized to treatment with ticagrelor or clopidogrel in the PLATelet inhibition and patient Outcomes (PLATO) trial. Methods The associations between sex subgroup and the primary composite outcomes, secondary outcomes, and major bleeding endpoints as well as interaction of sex subgroup with treatment effects were analysed using Cox proportional-hazards models. Results Sex was not significantly associated with the probability of the primary composite endpoint [adjusted hazard ratio (HR): 1.02 (0.91-1.16)], or other adverse cardiovascular endpoints. Ticagrelor was similarly more effective than clopidogrel in reducing rates of the primary endpoint in women 11.2 vs. 13.2% [adjusted HR: 0.88 (0.74-1.06)] and men 9.4 vs. 11.1% [adjusted HR: 0.86 (0.76-0.97)] (interaction P-value 0.78), all-cause death in women 5.8 vs. 6.8% [adjusted HR: 0.90 (0.69-1.16)] and men 4.0 vs. 5.7% [adjusted HR: 0.80 (0.67-0.96)] (interaction P-value 0.49), and definite stent thrombosis in women 1.2 vs. 1.4% [adjusted HR: 0.71 (0.36-1.38)] and men 1.4 vs. 2.1% [adjusted HR: 0.63 (0.45-0.89)] (interaction P-value 0.78). The treatments did not differ for PLATO-defined overall major bleeding complications in women [adjusted HR: 1.01 (0.83-1.23)] or men [adjusted HR: 1.10 (0.98-1.24)]. Sex had no significant association with these outcomes (interactions P = 0.43-0.88). Conclusion Female sex is not an independent risk factor for adverse clinical outcomes in moderate-to-high risk ACS patients. Ticagrelor has a similar efficacy and safety profile in men and women.

  • Ticagrelor Versus Clopidogrel in Elderly Patients With Acute Coronary Syndromes A Substudy From the Prospective Randomized PLATelet Inhibition and Patient Outcomes (PLATO) Trial
  • 2012
  • Ingår i: Circulation. Cardiovascular Quality and Outcomes. - 1941-7713 .- 1941-7705. ; 5:5, s. 680-688

    • Background-Elderly patients with acute coronary syndrome are at high risk of recurrent ischemic events and death, and for both antithrombotic therapy and catheter-based complications. This prespecified analysis investigates the effect and treatment-related complications of ticagrelor versus clopidogrel in elderly patients (>= 75 years of age) with acute coronary syndrome compared with those < 75 years of age. Methods and Results-The association between age and the primary composite outcome, as well as major bleeding were evaluated in the PLATelet inhibition and patient Outcomes (PLATO) trial using Cox proportional hazards. Similar models were used to evaluate the interaction of age with treatment effects. Hazard ratios were adjusted for baseline characteristics. The clinical benefit of ticagrelor over clopidogrel was not significantly different between patients aged >= 75 years of age (n=2878) and those < 75 years of age (n=15744) with respect to the composite of cardiovascular death, myocardial infarction, or stroke (interaction P=0.56), myocardial infarction (P=0.33), cardiovascular death (P=0.47), definite stent thrombosis (P=0.81), or all-cause mortality (P=0.76). No increase in PLATO-defined overall major bleeding with ticagrelor versus clopidogrel was observed in patients aged >= 75 years (hazard ratio, 1.02; 95% confidence interval, 0.82-1.27) or patients aged < 75 years (hazard ratio, 1.04; 95% confidence interval, 0.94-1.15). Dyspnea and ventricular pauses were more common during ticagrelor than clopidogrel treatment, with no evidence of an age-by-treatment interaction. Conclusions-The significant clinical benefit and overall safety of ticagrelor compared with clopidogrel in acute coronary syndrome patients in the PLATO cohort were not found to depend on age.

  • Pre-Hospital Treatment of STEMI Patients : A Scientific Statement of the Working Group Acute Cardiac Care of the European Society of Cardiology
  • 2012
  • Ingår i: Revista Española de Cardiología. - 0300-8932 .- 1579-2242. ; 65:1, s. 60-70
  • Tidskriftsartikel (refereegranskat)abstract
    • In ST-elevation myocardial infarction (STEMI) the pre-hospital phase is the most critical, as the administration of the most appropriate treatment in a timely manner is instrumental for mortality reduction. STEMI systems of care based on networks of medical institutions connected by an efficient emergency medical service are pivotal. The first steps are devoted to minimize the patient's delay in seeking care, rapidly dispatch a properly staffed and equipped ambulance to make the diagnosis on scene, deliver initial drug therapy and transport the patient to the most appropriate (not necessarily the closest) cardiac facility. Primary PCI is the treatment of choice, but thrombolysis followed by coronary angiography and possibly PCI is a valid alternative, according to patient's baseline risk, time from symptoms onset and primary PCI-related delay. Paramedics and nurses have an important role in pre-hospital STEMI care and their empowerment is essential to increase the eff ectiveness of the system. Strong cooperation between cardiologists and emergency medicine doctors is mandatory for optimal pre-hospital STEMI care. Scientific societies have an important role in guideline implementation as well as in developing quality indicators and performance measures; health care professionals must overcome existing barriers to optimal care together with political and administrative decision makers.
