BACKGROUND To assess the impact of gender as an independent risk factor for early and late morbidity and mortality following coronary artery bypass surgery. METHODS Perioperative and long-term data on all 4,823 patients undergoing isolated coronary bypass operations from November 1989 to July 1998 were analyzed. Of these patients, 932 (19.3%) were(More)
In this study, we examined the clinical outcome of coronary endarterectomy. From 1990 to 1998, 4839 patients underwent surgical revascularization. Coronary artery bypass graft surgery (CABG) was performed alone on 4516 patients, was combined with right coronary artery endarterectomy (RCA-E) in 242 patients, and was combined with left anterior descending(More)
Laser light scattered by nonstimulated rat cardiac muscle bathed in physiological saline containing a [Ca++] of 0.4-2.5 mM displays scattered-light intensity fluctuations (SLIF); the frequencies of both SLIF and resting force are Ca++ dependent. Direct inspection of these muscles by phase-contrast microscopy under incoherent illumination revealed the(More)
An antiserum against guinea pig epidermal myosin was used for the localization of myosin in frozen sections of human epidermis and cultured human epidermal cells. The antiserum gave a single precipitin band with epidermal myosin but did not cross react with muscle myosin or epidermal keratin in immunodiffusion plates. Strong staining, in the indirect(More)
BACKGROUND Preoperative renal failure increases the morbidity and mortality of coronary artery bypass graft (CABG) surgery. The results of CABG in patients with non-dialysis-dependent, mild renal insufficiency are unknown. METHODS From a population of 2978 consecutive patients undergoing isolated CABG from 1990 to 1996, 38 patients with preoperative renal(More)
BACKGROUND Previous studies have compared prosthetic valves on the basis of industry-labeled valve sizes. Unfortunately, the relationship between the labeled size and the true measured external or internal diameter differs between valve manufacturers. Therefore hemodynamic comparisons between prosthetic valves are inaccurate if based solely on(More)
BACKGROUND Clinical studies of myocardial protection rarely identify differences in hard clinical outcomes after surgery, either early or late, because most trials lack sufficient statistical power to deal with low-frequency events. METHODS Prospectively collected data concerning all isolated coronary bypass operations from November 1989 to February 2000(More)
