Myocardial protection by dilazep HCl, an antianginal drug and a potent calcium antagonist, against myocardial damage following acute ischemia and reperfusion was studied with respect to myocardial contractility in isolated blood-perfused canine left ventricular muscle. Myocardial function was expressed by percent recovery rate of maximal net developed tension. 1) The coronary infusion of dilaze...
Endotoxin [lipopolysaccharide (LPS)] causes tumor necrosis factor-α (TNF-α)-mediated myocardial contractile depression. Tolerance to the cardiac toxicity of LPS can be induced by a prior exposure to LPS or by pretreatment with glucocorticoids. The mechanisms by which the myocardium acquires tolerance to LPS remain unknown. LPS causes phosphorylation and degradation of inhibitory κB-α (IκB-α), r...
UNLABELLED Evaluation of possible cardiac complications is essential for safe and effective respiratory rehabilitation of patients with chronic respiratory diseases (CRDs). The aim of this study is to clarify the pathophysiology of electrocardiographic (ECG) changes during exercise and the prevalence of coronary artery disease (CAD) in CRD patients without a history of myocardial ischemia. ME...
OBJECTIVE To determine whether, among patients with non-Q wave myocardial infarction, the characteristics of the segment ST-T shifts at presentation in the diagnostic electrocardiogram can identify those with more severe coronary artery disease and predict a poor clinical outcome. DESIGN Prospective controlled clinical trial. SETTING Primary referral medical centre. PATIENTS 93 patients (...
STUDY OBJECTIVE To examine the clinical significance of precordial ST-segment changes in patients with acute Q-wave inferior wall myocardial infarction. DESIGN Prospective evaluation (clinical follow-up) of Q-wave inferior wall myocardial infarction over a 6-year period in patients who fulfilled the inclusion criteria. SETTING Coronary care unit at a university hospital. PATIENTS Two hund...
