The degree of exercise-induced cardiac dysfunction and its relation to the anaerobic threshold were evaluated in 23 patients with chronic heart disease. A symptom-limited exercise test was performed with a cycle ergometer with work rate increased by 1 W every 6 seconds. Left ventricular function, as reflected by ejection fraction, was continuously monitored(More)
BACKGROUND The delayed release of serum cardiac markers such as creatine kinase isoenzyme MB and equivocal early electrocardiographic changes have hampered a diagnosis of acute myocardial infarction (AMI) in the early phase after its onset. Therefore, a reliable serum biochemical marker for the diagnosis of AMI in the very early phase is desirable. (More)
AIMS We have recently reported that serum deoxyribonuclease I (DNase I) activity, which may be involved in apoptosis, increases abruptly in the early phase of acute myocardial infarction (MI) [Kawai Y, Yoshida M, Arakawa K, Kumamoto T, Morikawa N, Masamura K, Tada H, Ito S, Hoshizaki H, Oshima S, Taniguchi K, Terasawa H, Miyamori I, Kishi K, Yasuda T.(More)
AIMS Cardiac markers such as troponin T (c-TnT) have proven unsuitable for the detection of early and transient myocardial ischaemia. We recently reported that abrupt elevation of serum deoxyribonuclease I (DNase I) activity in the early stage of acute myocardial infarction could be used as a diagnostic marker. To evaluate whether serum DNase I could be(More)
BACKGROUND The cardiac output-O2 uptake (VO2) relation, which is thought to be linear and predictable in normal humans, has not been clarified in cardiac patients. We evaluated the relation between cardiac output and VO2 during the incremental exercise test in patients with previous myocardial infarction. METHODS AND RESULTS Twenty-two patients (age, 58.1(More)
A 61-year-old female underwent right hemihepatectomy and caudate lobectomy for hilar cholangiocarcinoma in 1999. Ten years later, increasing serum carbohydrate 19-9 was detected by routine follow-up. Subsequent positron emission tomography revealed an asymptomatic lesion in the right 11th rib. As the mass steadily grew in size, the lesion was resected en(More)
BACKGROUND Endoscopic biliary stenting (EBS) is one of the most important palliative treatments for biliary tract cancer. However, reflux cholangitis arising from bacterial adherence to the inner wall of the stent must be avoided. We evaluated the use of EBS above the sphincter of Oddi to determine whether reflux cholangitis could be prevented in(More)
The use of immunosuppressants after liver transplantation (LT) is associated with postoperative complications, including infections. A 49-year-old male underwent living-donor (LD) LT because of primary sclerosing cholangitis. He was treated with tacrolimus, mycophenolate mofetil, and steroids as immunosuppressants, discharged on postoperative day (POD) 40,(More)
