WebApr 15, 2024 · Background: Trabeculation, a key process in early heart development, is the formation of myocardial trabecular meshwork. The failure of trabeculation often leads to embryonic lethality. Support from endocardial cells, including the secretion of extracellular matrix (ECM) and growth factors is critical for trabeculation; however, it is unknown how … WebMay 17, 2024 · Myocardial infarction (MI) is the formal term for what is commonly referred to as a heart attack. It normally results from a lack of blood flow (ischemia) and oxygen (hypoxia) to a region of the heart, resulting in death of the cardiac muscle cells. WebThe competing theory states that the myocardium can never experience imbalance because it adapts its oxygen consumption (metabolism) to the oxygen supply. In other words, the myocardium will reduce its oxygen consumption – and thereby contractility – if sufficient oxygen is not available. str lr final form cooler
