This report reviews the author's involvement in the growth of ideas and basic concepts in myocardial ischemia resulting in the histological changes of myocardial infarction. Concepts arising from the study of myocardial substrate utilization, activation of the inducible form of nitric oxide synthase and production of prostacyclin and thromboxane in the infarcted heart are presented. New approaches are discussed dealing with the effects of nonsteroidal anti-inflammatory drugs on myocardial production of nitric oxide and prostanoids, and with the relevance of the inducible form of cyclooxygenase. The review also records a number of significant similarities between angiogenesis in the ischemic heart and some cancers. Angiogenesis in both instances originates from inflammatory reactions, illustrating how different tissues and organs such as ischemic heart muscle and cancer react to similar pathological stimuli in an identical manner. This multifocal approach opens new concepts on myocardial ischemia and cancer.
