  • Echocardiogram

 From the eye of modern medicine and science, the heart is an organ in the human body. The heart is a vital organ that can be fine in the chest area. The specific area in the chest is known as the mediastinum. Why is the heart so important? The heart is vital in channelling and maintaining adequate blood flow to the entire body. The heart is comparable to an engine that receives and ejects blood to multiple areas within the body. Blood vessels are the tunnels or tubes that direct the blood flow and complete the action started by the heart. The blood vessels, heart, and blood made up a system known as the cardiovascular system. Blood is a medium in nourishing and maintaining the survival of other body cells. Blood carries nutrients and oxygen to entire body cells and organs. Blood also carries away waste products by the cells such as the carbon dioxide gas for the body to expel it out. 

  The definition of health is the well-being state of the biopsychosocial components. The ‘bio’ component is referring to human hardware or body organs and parts. The ‘psycho’ component is referring to the software or the human mental state.

A healthy individual is a person with healthy and functioning biopsychosocial components. The unwell heart is referring to the impaired ‘bio’ component. Most of the diseases of the human body are well studied and most of them already have specific treatment. An unhealthy heart could mean many things. There are many diseases of the heart. The examples are:

  • Coronary heart disease
  • Congenital heart disease
  • Valvular heart disease
  • Heart failure

 Congenital heart disease is the heart disease that affects the newborn. There are a few heart diseases that may affect the newborn such as the Tetralogy of Fallot (TOF). Valvular heart disease is a state of unwell or unfunctioned valves within the heart. Heart failure is a medical condition where the heart is not pumping well or in a failure state.
