The human heart is unique, from development, to function, and potential health issues. The development of the human heart begins before birth. The development of the heart has various stages. According to Cynthia Thaik, M.D., the first stage of heart development “begins when cardiac precursor cells migrate to form a primitive heart tube” (16). After a primitive heart tube is formed the second stage …show more content…

This prevents oxygen-rich blood from being delivered to the heart muscle beyond that blockage and that of the heart begins to die” (“Cardiovascular …show more content…
The Cleveland Clinic also said, “Metabolic syndrome is thought to be the leading contributor to the development of heart attacks and strokes” (“Disease & Conditions”). Additionally, this disease is know to be a contributor to insulin resistance. “Metabolic syndrome is associated with ‘insulin resistance’, which means that the body does not use insulin efficiently to lower glucose and triglyceride levels” (“Disease & Conditions”). Although little is known about the cause of metabolic syndrome, it continues to be a large problem among Americans. 
 A dysfunctioning heart is also prone to, “One of the leading causes of death in the United States having to do with blood flow to the heart”, coronary artery disease (Thaik 32). The development of this disease is set in motion, “…when the major blood vessels that supply your heart with blood, oxygen and nutrients (coronary arteries) become clamped or diseased” (“Coronary Artery Disease”). This disease can be caused by many factors and can be contracted at any

    Though heart failure can occur suddenly, weakening of the heart is more likely to slowly develop over a period of time, often over many years as the heart becomes weaker and is unable to work as efficiently, which is why is it more prominent in the elderly population. Typically conditions and diseases that damage or overwork the heart lead to congestive heart failure. The major conditions and factors that cause congestive heart failure include: • Coronary artery disease • Heart valve disease • High blood pressure • Hypertension • Valve conditions • Cardiomyopathy • Diabetes • Alcohol abuse • Smoking Coronary artery disease, also known as ischaemic heart disease, results from the gradual blocking of the coronary artery by fatty deposits called plaque.

Cardiovascular disease currently stands as the leading cause of death in the United States, affecting both genders indiscriminately and is responsible for almost fifty percent of deaths that occur. It has recently become an area of intense scientific and medical investigation in collaboration with Public Health to ameliorate this health crisis.
