Traumatic aortic rupture (TAR) is a pathological entity with a high mortality, both spontaneous and perioperative. Delayed surgical repair has been proposed when associated lesions are stabilized. The aim of this study was to validate MRI for detecting both the presence and type of TAR and to monitor posttraumatic aneurysm and associated lesions.

The most important factor for improving out-of-hospital ventricular fibrillation survival rates is early defibrillation. This can be achieved if small, lightweight, inexpensive automatic external defibrillators are widely disseminated. Because automatic external defibrillator size and cost are directly affected by defibrillation waveform shape and because of the favorable experience with truncated biphasic waveforms in implantable cardioverter-defibrillators, we compared the efficacy of a truncated biphasic waveform with that of a standard damped sine monophasic waveform for transthoracic defibrillation.

Patients with early Thrombolysis in Myocardial Infarction (TIMI) grade 2 flow after thrombolysis appear to have outcomes similar to thrombolytic failures. To evaluate the origin and evolution of early TIMI 2 flow, we examined early and late angiographic and ventriculographic data from the Global Utilization of Streptokinase and TPA for Occluded Arteries (GUSTO-1) angiographic study.
3091. Relationship to blood pressure of combinations of dietary macronutrients. Findings of the Multiple Risk Factor Intervention Trial (MRFIT).

来源: Circulation. 1996年94卷10期2417-23页
Elevated blood pressure remains a widespread major impediment to health. Obesity and specific dietary factors such as high salt and alcohol intake and low potassium intake adversely affect blood pressure. It is a reasonable hypothesis that additional dietary constituents, particularly macronutrients, may also influence blood pressure.
3092. Distinct effects of recombinant desulfatohirudin (Revasc) and heparin on plasma levels of fibrinopeptide A and prothrombin fragment F1.2 in unstable angina. A multicenter trial.

Thrombin plays an important role in the pathogenesis of acute coronary thrombosis. We studied the effects of a direct thrombin inhibitor, recombinant desulfatohirudin, and heparin on plasma levels (at 0, 4, 12, and 24 hours) of fibrinopeptide A (FPA), which reflects thrombin action, and prothrombin fragment F1.2, which reflects thrombin generation, in patients with unstable angina.

来源: Circulation. 1996年94卷10期2381-8页
The association of serum lipids with coronary heart disease has been studied extensively in middle-aged men and, to a lesser extent, in similar women. Less well defined are lipid variables predictive of CHD in individuals of age > or = 60 years.

来源: Circulation. 1996年94卷10期2369-72页
There is accumulating experimental, epidemiological, and clinical evidence of an association between anti-oxidant vitamin intake and reduced risk of coronary heart disease. Using data from the Cholesterol Lowering Atherosclerosis Study (CLAS), we explored the association of self-selected supplementary antioxidant vitamin intake on the rate of progression of early preintrusive atherosclerosis.

Whether prophylactic insertion of an implantable cardioverter defibrillator (ICD) improves the survival of high-risk patients undergoing coronary artery bypass graft surgery (CABG) is being assessed in the CABG Patch Trial. This report describes the surgical aspects of the study.
3097. Comparison of high-dose with low-dose aspirin in patients with mechanical heart valve replacement treated with oral anticoagulant.
There are no reported studies on the safety and efficacy of low-dose aspirin with low-intensity oral anticoagulation in patients with heart valve replacement. In this study, we compared the use of 100 mg/d aspirin with 650 mg/d aspirin in the prevention of systemic embolism and vascular death in patients with heart valve replacement who were being treated with oral anticoagulants with a target international normalized ratio (INR) of 2.0 to 3.0.
3098. AREVA: multicenter randomized comparison of low-dose versus standard-dose anticoagulation in patients with mechanical prosthetic heart valves.

来源: Circulation. 1996年94卷9期2107-12页
Moderate anticoagulation may be proposed to reduce the risk of hemorrhage for certain patients with a mechanical prosthesis, but the consequences for risk of thromboembolism are debated.
3099. Effects of integrelin, a platelet glycoprotein IIb/IIIa receptor antagonist, in unstable angina. A randomized multicenter trial.
作者: S P Schulman.;P J Goldschmidt-Clermont.;E J Topol.;R M Califf.;F I Navetta.;J T Willerson.;N C Chandra.;A D Guerci.;J J Ferguson.;R A Harrington.;A M Lincoff.;S J Yakubov.;P F Bray.;R D Bahr.;C L Wolfe.;P G Yock.;H V Anderson.;T W Nygaard.;S J Mason.;M B Effron.;A Fatterpacker.;S Raskin.;J Smith.;L Brashears.;P Gottdiener.;C du Mee.;M M Kitt.;G Gerstenblith.

Although aspirin is beneficial in patients with unstable angina, it is a relatively weak inhibitor of platelet aggregation. The effect of Integrelin, which inhibits the platelet fibrinogen receptor glycoprotein (GP) IIb/IIIa, on the frequency and duration of Holter ischemia was evaluated in 227 patients with unstable angina.
3100. The Asp9 Asn mutation in the lipoprotein lipase gene is associated with increased progression of coronary atherosclerosis. REGRESS Study Group, Interuniversity Cardiology Institute, Utrecht, The Netherlands. Regression Growth Evaluation Statin Study.

Many patients suffering from premature coronary artery disease report a family history for such events. A mutation in a particular gene, which confers susceptibility for atherosclerosis, will be found more frequently in individuals suffering from coronary atherosclerosis than in the general population. We have recently reported the identification of an Asp9 Asn substitution in the lipoprotein lipase (LPL) enzyme. We analyzed the impact of this mutation on the progression of coronary atherosclerosis and the effect of pravastatin in both carriers and noncarriers.
