Contrary to popular belief, most of the cardiovascular attacks don't happen overnight or suddenly, i.e. this condition is actually a result of many internal health problems that have been piling-up for many months, years or even decades. The underlying cause of all myocardial infarctions is the decreased vascular supply, i.e. dip in volume of oxygenated blood routed towards the heart's muscles. The human heart is essentially a pump-like muscular organ that constantly needs oxygenated blood to function properly. When there is a severe or total obstruction in the arteries, the risk of cardiovascular problem rise exponentially. However, such problems are not going to happen every time there is some drop in the vascular supply to the cardiac chamber as it can cope up to some extent but when a vascular clot develops in the arteries or when there is excessive thickening within the arterial walls and there is negligible or nil supply of blood to a certain section(s) of the cardiac muscles, serious cardiovascular problems can occur.
During this phase, the muscles are suffocated or suffer necrosis, i.e. tissue death due to deprivation of nutrition. The fall in oxygenated vascular supply to the cardiac section is also referred to as Ischemia and thus, Ischemia is commonly referred to as the reason behind most myocardial infarctions. Ischemia can be established in many ways. As mentioned, the thickening of arterial walls due to deposits or plaques of cholesterol are a primary reason for this. Such arterial walls are called atherosclerotic, which refers to the fact that they have developed a narrower-than-normal pathway due to cholesterol deposits. Atherosclerosis takes some time to become a damaging problem. Other reasons include a blood clot due to vascular problems.
