RESUMO

Background: It is still uncertain whether coronary bifurcations with lesions involving a large side branch (SB) should be treated by stenting the main vessel and provisional stenting of the SB (simple) or by routine two-stent techniques (complex). We aimed to compare clinical outcome after treatment of lesions in large bifurcations by simple or complex stent implantation. Methods: The study was a randomised, superiority trial. Enrolment required a SB≥2.75 mm, ≥50% diameter stenosis in both vessels, and allowed SB lesion length up to 15 mm. The primary endpoint was a composite of cardiac death, non-procedural myocardial infarction and target lesion revascularisation at 6 months. Two-year clinical follow-up was included in this primary reporting due to lower than expected event rates. Results: A total of 450 patients were assigned to simple stenting (n=221) or complex stenting (n=229) in 14 Nordic and Baltic centres. Two-year follow-up was available in 218 (98.6%) and 228 (99.5%) patients, respectively. The primary endpoint of major adverse cardiac events (MACE) at 6 months was 5.5% vs 2.2% (risk differences 3.2%, 95% CI -0.2 to 6.8, p=0.07) and at 2 years 12.9% vs 8.4% (HR 0.63, 95% CI 0.35 to 1.13, p=0.12) after simple versus complex treatment. In the subgroup treated by newer generation drug-eluting stents, MACE was 12.0% vs 5.6% (HR 0.45, 95% CI 0.17 to 1.17, p=0.10) after simple versus complex treatment. Conclusion: In the treatment of bifurcation lesions involving a large SB with ostial stenosis, routine two-stent techniques did not improve outcome significantly compared with treatment by the simpler main vessel stenting technique after 2 years. Trial registration number: NCT01496638.

RESUMO

AIMS: The aim of this study was to evaluate the functional result immediately post PCI and at nine-month follow-up, and to ascertain how often a functionally optimal result of >0.95 can be achieved in long coronary lesions treated with long second- or newer-generation DES. METHODS AND RESULTS: Patients receiving DES measuring ≥30 mm with FFR value ≤0.8 were included in the study. Stent length was defined as long (30 to 49 mm; L-DES) and ultra-long (≥50 mm; UL-DES). Angiographic and FFR evaluation was performed before and after PCI and at nine-month follow-up. A total of 74 patients each received a mean stent length of 50.72±14.6 mm. Mean FFR post PCI was 0.88±0.06. An optimal post PCI FFR value of >0.95 was achieved in only 9/74 patients (12.2%), and was not achieved in any UL-DES patients. Only 12/74 (16.2%) had FFR post PCI of 0.91 to 0.95; 8/74 (10.8%) patients remained ischaemic (≤0.8). FFR gradient across the stent was higher in UL-DES patients compared to L-DES patients (0.07±0.03 vs. 0.04±0.03; p=0.001). At follow-up, the angiographic restenosis rate was 4.7%, and the functional restenosis rate was 15.1%. CONCLUSIONS: The FFR result post PCI was suboptimal in the majority of patients treated with long DES and was particularly poor when the total stent length exceeded 50 mm.

RESUMO

Therapeutic hypothermia is method used to improve the neurological status of patients who are at risk of ischaemia after myocardial infarction. We report a case of a 28-year-old woman who suffered acute myocardial infarction complicated by ventricular fibrillation. The patient was successfully resuscitated. Invasive and non-invasive medical treatment was applied including therapeutic hypothermia. Success was achieved due to adequate public reaction, fast transportation, blood vessel revascularization and application of therapeutic hypothermia. The patient was successfully discharged after one week of treatment, and just minor changes in heart function were present.

RESUMO

OBJECTIVE: Postmenopausal phase expresses many unfavourable physiological changes that lead to increased risk for cardiovascular disease. We compared the effect of two sympatholytic antihypertensive drug treatments, the centrally acting imidazoline receptor-1 agonist moxonidine and peripherally acting beta-blocking agent atenolol on sensitive inflammatory markers in overweight postmenopausal women with diastolic hypertension. METHODS: This was a multicentre, multinational double-blinded, prospective study comparing moxonidine (0.3 mg twice daily) with atenolol (50 mg once daily) in 87 hypertensive postmenopausal overweight women who were not taking hormone therapy. Sensitive C-reactive protein, IL-6, TNFalpha, TNFalpha-RII and adiponectin were determined in the beginning of the study and after 8 weeks of medical treatment. RESULTS: TNFalpha increased in atenolol and decreased in moxonidine group (P = 0.0004 between the groups). Adiponectin concentration decreased dramatically in atenonol but did not change in moxonidine treatment group (P < 0.0001 between the groups). In logistic regression analysis only treatment group showed an independent effect on changes in adiponectin and TNFalpha concentrations. CONCLUSION: We believe that centrally acting sympatholytic agent moxonidine is beneficial in the treatment of postmenopausal women with hypertension by reducing inflammatory cytokine TNFalpha without changing protective adiponectin level.

RESUMO

Randomized controlled trials that compared primary percutaneous transluminal coronary angioplasty with thrombolysis have shown that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction. Three large myocardial infarction registries - MITI, NRMI-2 and French registry - failed to show an advantage of primary angioplasty compared with thrombolysis. One of the latest trials mentioned in this paper restored the place of primary angioplasty as superior to thrombolysis in acute myocardial infarction. Data of patients treated with primary percutaneous transluminal coronary angioplasty in Clinic of Cardiology of Vilnius University are presented.
