Tackling the Incidence of Cardiovascular Diseases Essay

Tackling the Incidence of Cardiovascular Diseases - Essay ExampleAccording to statistics obtained from the universe of discourse Health Organization (WHO), CVDs are the primary cause of deaths worldwide. It is estimated that more people die from CVDs annually than from every other disease. The WHO further reports that in 2004, CVD was responsible for 17.1 million deaths globally. This represented 29% deaths worldwide. Of these, 7.2 million deaths were due to coronary center field disease, while stroke was associated with 5.7 million deaths. The WHO estimates that by 2030, deaths due to CVD would amount to 23.6 million, most of which will assimilate resulted from stroke and affection disease (WHO Fact Sheet). In sight of this grim reality, it is high cartridge holder that scientists explore beyond conventional medication. Current treatment of CVD involves balloon angioplasty, heart transplantation, coronary artery rotate surgery, and repair or replacement of valves. Though wides pread, there are always implications and setbacks to these methods. In most cases of heart failure, congenital cardiac anomalies and post-myocardial infarctions, the only possible cure is heart transplantation because the ischemically injured failing heart lacks contractile myocardium, functional vasculature, and electrical integrity, which has made treatment of the underlying injury untenable (Ott, Davis and Taylor, 2005). However, due to a severe scarcity of organ donors and the fear of organ rejection, transplantation science needs a matured transformation. Therefore, in this proposal, I put forth possible areas of research in tissue engineering and regenerative medicine that are emerging as promising frontiers in transplantation technology, and how they can be used in tackling the incidence of cardiovascular diseases. Here, I wish to explore new technologies in tissue engineering and converse how I will approach my research objectives for postdoctoral studies in this field. Con text and literature review Most of the present-day(prenominal) research is focused on tissue engineering to reproduce functional myocardium, heart valves and even the inherent heart from the cells of the affected role. In the treatment and prevention of heart failure, technologies that induce cardiac repair are existence sought after. Therefore, cell-based regenerative medicine is the first step in this direction (Ott and Taylor, 2006). By combining beginning and primogenitor cells with increasingly complex scaffold materials and culture conditions, it is possible to create an entirely new organ derived from the patients own cells (Song and Ott, 2011). Studies have been done on cardiac stem cells isolated from uncommitted cardiac progenitor cells of ventricles. These cells can mature into smooth muscle, endothelial and cardiomyocyte cells that can be used to produce organs or parts of an organ (Ott et al, 2007). In another approach, skeletal myoblasts, myogenic or angiogenic p recursors, hematopoietic progenitor cells and blood-derived or bone marrow mesenchymal cells can be used for cardiovascular repair (Ott, McCue and Taylor, 2005). Using cardiac derived stem cells, progenitor cells or cardiomyocytes, a functional and contractile myocardium can be engineered using biocompatible scaffold materials (Tee et al, 2010, p. 683). sustain materials are required to guide the division of cells to enable the development of an organ just like an extracellular matrix. Attempts are being made to make patient specific scaffolds through bio manufacturing (Bartolo et al, 2009, p. 212). Failed cardiovascular components can be replaced with biocompatible tissues that have the potential to rapidly restore the lost function and slowly regenerate by remodeling
