To develop guidelines for ranking the urgency with which patients with angiographically proven coronary disease need revascularisation procedures, factors that a panel of cardiac specialists agreed were likely to affect urgency were incorporated into 438 fictitious case-histories. Each panelist then rated the cases on a 7-point scale based on maximum(More)
The clinical experience with 37 patients with acute transmural inferior wall myocardial infarction who were assessed for evidence of right ventricular involvement is reported. On the basis of currently accepted hemodynamic criteria, 29 patients (78%) had evidence suggestive of right ventricular infarction. However, only 5 (20%) of 25 patients demonstrated(More)
A panel of 16 cardiologists and cardiac surgeons rated 438 case scenarios for the maximum acceptable delay prior to revascularization, using a scale with seven interventional time frames and two nodes for designating dubious or inappropriate cases. If consensus was defined as agreement by 12 or more panelists, only 1.4 percent of the case scenarios showed(More)
Objective:To determine the effects of age and work status on whether and where cardiovascular specialists would place hypothetical patients in the queue for coronary surgery. Materials and methods:Mailed survey presenting a set of clinical scenarios either to be rated on a scale with 7 time frames for urgency of need or to be designated as(More)
OBJECTIVE To examine the long-term benefits and safety of aerobic training in patients with chronic heart failure. DESIGN Non-randomised control trial with 52 weeks follow up. SETTING Outpatient cardiac rehabilitation referral centre. PATIENTS Patients with compensated chronic heart failure (mean (SD) age 62 (6) years, New York Heart Association stage(More)
Fifteen patients with chronic liver disease having a peritoneovenous shunt for chronic intractable ascites were studied prospectively for renal function and hemodynamic changes during balance studies, pre-, peri-, and postoperatively. Shunt insertion caused a rapid redistribution of ascites into the intravascular compartment with hemodilution and(More)
Niridazole alone (at 50 mg/kg/day) and particularly in combination with azathioprine and prednisolone showed potent immunosuppressive activity, far surpassing that produced by conventional agents, in the rat heterotopic cardiac allograft model. Benzoylmetronidazole or metronidazole (at 50 mg/kg/day) either alone or in combination with azathioprine and(More)
OBJECTIVES To determine the frequency of major adverse events among patients awaiting coronary revascularization; to assess the match between referring physicians' estimates of urgency, a computer-generated multifactorial urgency rating score and actual waiting times; to determine the changes in waiting times as capacity for bypass surgery increased; and to(More)
The efficacy and safety of recombinant tissue plasminogen activator (rt-PA) administered on a dosing per weight basis was evaluated in a randomized, placebo-controlled, double-blind trial in 115 patients with acute myocardial infarction. The principal outcomes were global and regional left ventricular function in the distribution of the qualifying(More)
