Coronary heart disease or Coronary Artery Disease as it is commonly known is disease of the arteries attached to outside of the heart which become inflamed and blocked to varying degrees,however a total blockage causes a heart attack(myocardial infarction). Coronary artery disease has many causes such as genetics,smoking,high fat diet,high cholesterol diet,sedentary lifestyle,hyperlipidemia and many more The best way to avoid coronary artery disease is to eat a heart healthy diet,don't smoke,get exercise daily, control your weight and if you are an at risk person have regular check-ups.

Blood flow patterns and flow related stresses through the cardiovascular tree contribute to the pathogenesis of a number of disorders and the characterisation of health risks. Complex flows present in arteries are considered to be one of the primary factors involved in the initiation and propagation of atherosclerosis and arterial stenosis. In coronary arteries, where the geometry influences the generation of secondary flows, arterial plaque tends to localise along the inner curvatures of bends and the near sites of bifurcations. Flow patterns present in human arterial systems and the impact of external factors such as smoking and food diet that affect the physiological reactions of the cardiovascular system are thought to play an important role in the initiation and propagation of atherosclerosis and arterial stenosis.. A heart attack (myocardial infarction) occurs when an area of heart muscle dies or is permanently damaged because of an inadequate supply of oxygen to that area. Most heart attacks are caused by a clot that blocks one of the coronary arteries (the blood vessels that bring blood and oxygen to the heart muscle). The clot usually forms in a coronary artery that has been previously narrowed from changes related to atherosclerosis. The atherosclerotic plaque (buildup) inside the arterial wall sometimes cracks, and this triggers the formation of a clot, also called a thrombus. A clot in the coronary artery interrupts the flow of blood and oxygen to the heart muscle, leading to the death of heart cells in that area. The damaged heart muscle loses its ability to contract, and the remaining heart muscle needs to compensate for that weakened area
