New information related to the mechanism of heart sounds and murmurs, and a more detailed understanding of some aspects of cardiac function, permit a more complete and accurate interpretation of auscultatory signs in patients with ischemic heart disease. The diminished second sound in such patients is now recognized to reflect isovolumic relaxation, and the diminished first sound probably reflects impaired isovolumic contraction. Ejection murmurs can be interpreted in light of their relation to turbulent flow. The variability of regurgitant murmurs in the papillary muscle dysfunction syndrome seems to be explained by new observations related to the function of the papillary muscle.

    The article discusses the need for a treatment for asymptomatic myocardial ischemia which is believed to be the precursor of sudden cardiac death. A best treatment is needed since ischemia involves a differential sensitivity to pain which affects the personality of an individual. In addition,...

    Abstract: Ischemia–reperfusion of the heart and other organs results in the accumulation of unesterified arachidonic acid (AA) via the action of membrane-bound phospholipases, primarily phospholipase A2. AA can be metabolized by the classical cyclooxygenase (COX) and lipoxygenase (LOX)...

    Abstract??Blocking either the Nachannel or the Na/Hexchanger (NHE) has been shown to reduce Naand Ca2overload during myocardial ischemia and reperfusion, respectively, and to improve post-ischemic contractile recovery. The effect of combined blockade of both Nainflux routes on ionic homeostasis...
