Assessment and clinical applications of myocardial efficiency
نویسنده
چکیده
Myocardial work and its metabolic cost are important parameters in the pathogenesis and management of cardiovascular diseases. Myocardial efficiency, unlike other commonly used measures of cardiac function, accounts for both parameters. It has been demonstrated that myocardial oxygen demand can be reliably quantified using positron-emitting radionuclide tracers of oxygen flux, whereas cardiac work can be estimated from stroke volume and mean arterial pressure. Assessment of myocardial efficiency from these parameters has been shown to be very useful in providing an understanding of the pathogenesis of many cardiovascular diseases and the effects of therapeutic interventions.

The purpose of this study was to induce myocardial infarction (MI) and compare the echocardiographic parameters and mortality ratio of Lewis inbred and Wistar outbred strain before and after the procedure to help choose the best one for MI studies. In this study MI was induced in 46 Lewis and 34 Wistar by occlusion of left anterior descending artery (LAD). Doppler, two-dimensional (2-D) and 2-D...
متن کاملA periodontal health assessment of hospitalized patients with myocardial infarction
Background: Recent researches have known long term infections such as periodontal disease to be related with the process of atherosclerosis. Periodontitis causes peripheral inflammation and immune cell stimulation which leads to an increase in C - reactive protein (CRP) and IgA Ab and there is a definite relation between cardiovascular disease, CRP increase and Periodontitis. The aim of this st...
