Multicenter Study Comparative StudyFondaparinux Use in Patients With COVID-19: A Preliminary Multicenter Real-World Experience.
The use of heparin has been shown to decrease the mortality in hospitalized patients with severe COVID-19. The aim of our study was to evaluate the clinical impact of venous thromboembolism prophylaxis with fondaparinux versus enoxaparin among 100 hospitalized COVID-19 patients. ⋯ In a median follow-up of 28 (IQR: 12-45) days, no statistically significant difference in venous thromboembolism (14.5% vs. 5.3%; P = 0.20), MB and clinically relevant non-MB (3.2% vs. 5.3%, P = 0.76), ARDS (17.7% vs. 15.8%; P = 0.83), and in-hospital mortality (9.7% vs. 10.5%; P = 0.97) has been shown between the enoxaparin group versus the fondaparinux group. Our preliminary results support the hypothesis of a safe and effective use of fondaparinux among patients with COVID-19 hospitalized in internal medicine units.

Randomized Controlled Trial Multicenter Study Comparative StudyAssessment of Ticagrelor Versus Clopidogrel Treatment in Patients With ST-elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.
Ticagrelor improves the clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). However, few studies have directly compared the efficacy and safety of ticagrelor against clopidogrel, an oral, thienopyridine-class antiplatelet drug. This study compared the efficacy and safety of ticagrelor and clopidogrel in patients with STEMI undergoing PPCI. ⋯ Among patients with STEMI undergoing PPCI, ticagrelor reduces the incidence of MACCE and the composite end point of cardiovascular death, nonfatal MI, and stroke compared with clopidogrel. Ticagrelor also reduces the need for GPIIb/IIIa inhibitors. However, no significant difference was observed in the risk of bleeding between the 2 groups.

Multicenter Study Observational StudyDoes antiarrhythmic drug during cardio-pulmonary resuscitation improve the one-month survival: The SOS-KANTO 2012 study.
Antiarrhythmic drugs (AAD) are often used for fatal ventricular arrhythmias during cardiopulmonary resuscitation (CPR). However, the efficacy of initial AAD administration during CPR in improving long-term prognosis remains unknown. This study retrospectively evaluated the effect of AAD administration during CPR on 1-month prognosis in the SOS-KANTO 2012 study population. ⋯ Significantly greater 1-month survival was observed in the AAD group compared with the non-AAD group. However, the effect of ADD on the likelihood of a favorable neurological outcome remains unclear. The findings of the present study may indicate a requirement for future randomized controlled trials evaluating the effect of ADD administration during CPR on long-term prognosis.

Randomized Controlled Trial Multicenter Study Clinical TrialRACTS: a prospective randomized antiplatelet trial of cilostazol versus ticlopidine in patients undergoing coronary stenting: long-term clinical and angiographic outcome.
We compared the efficacy of cilostazol for the prevention of late restenosis and acute or subacute stent thrombosis with that of ticlopidine. Cilostazol has been used for antiplatelet therapy after coronary stent implantation, but the results are controversial. Patients scheduled for stent implantation were randomly assigned to receive either cilostazol (100 mg twice daily for 6 months, n=201) or ticlopidine (250 mg twice daily for 1 month, n=196). ⋯ Medication withdrawn because of drug-related side effects tended to be higher in the ticlopidine group than that in the cilostazol group (3.5% vs 8.2%, P=0.054). At follow-up angiography, the minimal luminal diameters (2.31+/-1.06 vs 2.10+/-1.16, P=0.057) tended to be larger and the restenosis rates lower (23.3% vs 30.9%, P=0.086) in the cilostazol group than in the ticlopidine group. Aspirin plus cilostazol is a comparable antithrombotic regimen to aspirin plus ticlopidine after elective coronary stenting, but the rate of target lesion revascularization was significantly lower in the cilostazol group than in the ticlopidine group.

Randomized Controlled Trial Multicenter StudySTRIDE 1: effects of the selective ET(A) receptor antagonist, sitaxsentan sodium, in a patient population with pulmonary arterial hypertension that meets traditional inclusion criteria of previous pulmonary arterial hypertension trials.
Sitaxsentan (SITAX; Thelin, Encysive Corporation, Bellaire, TX, U. S. A.) is a highly selective oral endothelin-A receptor antagonist. ⋯ The results were: change for placebo (mean +/- SE) vs change for sitaxsentan (mean +/- SE) vs treatment effect (mean), all statistically significant: 6-minute walk (m): -26 +/- 13, 39 +/- 10, 65; mean right atrial pressure (mmHg): 2.1 +/- 0.8, -1.2 +/- 0.5, -3.3; mean pulmonary arterial pressure (mmHg): 0.4 +/- 1.5, -4.7 +/- 1.5, -5.1; cardiac index (L/min per m): -0.09 +/- 0.09, 0.38 +/- 0.06, 0.47; pulmonary vascular resistance (dyne.s.cm): 85 +/- 60, -274 +/- 47, -359. A 45% improvement in functional class was seen in sitaxsentan-treated patients (P = 0.0005). Thus, in the STRIDE-1 subpopulation that met enrolment criteria of previous pulmonary arterial hypertension trials, improvement in efficacy parameters with sitaxsentan therapy was even greater than seen in the entire STRIDE-1 population.
