Cardiovascular Disease (CVD), which includes hypertension, stroke, congestive heart failure, and coronary heart disease has been the number one killer people in the United States for the past 109 years, except for 1918 because of the flu epidemic. Approximately 2,600 Americans die each day from CVD, which equates to one person every 34 seconds. [2]

CVD can deprive heart tissue of oxygen killing the muscle (cardiomyocytes) which can form scar tissue. This leads to an overload of the remaining cells trying to keep up with normal output which leads to heart failure and death. [2]

Using different types of stem cells, including Hematopoietic stem cells, heart tissue can be regenerated. This could treat or even cure CVD. [2]
