Myocardial Ischemia
Difficulties in studying myocardial metabolism with adequate time resolution have led to contradictory conclusions regarding the mechanisms causing contractile abnormalities during the early stages of ischemia. In acutely instrumented swine, we investigated whether abnormalities in subendocardial ATP, phosphocreatine, or lactate content develop rapidly enough during the first few heart beats af...
متن کاملMyocardial Ischemia
Regional myocardial blood flow and contractile function in ischemic myocardium are well matched, and there is no evidence for an oxygen supply/demand imbalance. Thus, myocardial ischemia is lack of coronary blood flow with electric, functional, metabolic, and structural consequences for the myocardium. All therapeutic interventions must aim to improve blood flow to ischemic myocardium as much a...
متن کاملIschemia-modified albumin and myocardial ischemia.
Sbarouni et al. (1) reported on “Ischemia-Modified Albumin [IMA] in Relation to Exercise Stress Testing [EST]” in a previous issue of the Journal. Although the investigators found significant differences in the IMA values at baseline, peak exercise, and after EST, there was no relation between the IMA changes and the result of the EST. The researchers stated that changes in IMA levels do not re...
متن کاملContracture During Myocardial Ischemia
The effects of inosine (INO) on substrate metabolism and rigor formation in ischemic myocardium were examined in isolated rabbit hearts. Metabolite content was assessed in tissue extracts by chemical analysis and in the whole heart by `C and 31P nuclear magnetic resonance spectroscopy. In ischemic hearts metabolizing either [3-'3Clpyruvate or [1-13C glucose, 1 mM INO increased both total and D3...
متن کاملMyocardial ischemia and viability
This paper addresses the question of whether and how MCG tests that assess ischemia or viability of the myocardium can add to the diagnostic information gained from standard procedures in asymptomatic and symptomatic patients. We review the diagnostic performance of the exercise electrocardiogram (ECG), the exercise and pharmacological (stress) echocardiogram, the exercise and pharmacological m...
