The principal cause of the ischemic heart disease is the reduction of the amount of blood which the arteries provide for the heart to function at normal parameters. There are many people who die from ischemic heart disease, especially in the western countries.

The ischemia starts by some fatty deposits gathered up in the cells of the wall which surrounds the coronary arteries(the main source of blood for the heart). The fat deposits grow step by step into large twigs of the coronary arteries, process called atherosclerosis which brings about the narrowing of the coronary arteries which irrigate the heart muscle.

When you have ischemic heart disease ischemia the heart muscle is damaged because it doesn’t receive the needful oxygen and this is the cause of ischemia. A heart attack occurs when the blood vessels are completely closed.
Ischaemia refers to an insufficient amount of blood. The coronary arteries are the only source of blood for the heart muscle. If this coronary arteries are blocked, the blood supply will reduce. The atherosclerosis is one of the most common cause of the ischemic heart disease.

A multitude of factors are responsible for the development of Ischaemic Heart Disease. The major risk factors are smoking, diabetes mellitus and cholesterol levels. Those with Hypercholesterolaemia (elevated blood levels of cholesterol) have a much higher tendency to develop the disease. There is also the theory that Hypertension is a risk factor in the development of Ischaemic Heart Disease, Genetic and hereditary factors may also be responsible for the disease. Males are more prone to Ischaemic Heart Disease.

However, in post-menopausal women, the risk is almost similar to that of men. Stress is also thought to be a risk factor, though there has been a great deal of debate on this factor of late. The disease process occurs when an atheromatous plaque forms in the coronary vessels, leading to narrowing of the vessel walls and obstructing blood flow to the musculature of the heart. Complete blockage results in deficient oxygenation and nutrient supply to the heart tissues, leading to damage, death and necrosis of the tissue, which is known as Myocardial Infarction (heart attack).

Causes Of Ischaemic Heart Disease

1.Stress is also thought to be a risk factor.
2.Genetic and hereditary factors may also be responsible for the disease.
3.Hypertension is also a risk factor in the development of Ischemic Heart Disease
4.Those with Hypercholesterolemia have a much higher tendency to develop the disease.
5.The major risk factors are smoking, diabetes mellitus and cholesterol levels.

Ischaemic heart disease is more commonly known as coronary artery disease. Of course, the mere mention of the words “heart disease” surges enough panic through our minds that further understanding of it can be difficult. ‘Ischaemia’ as a term can be simply put as a condition that is categorized by reduced blood flow (hence ‘oxygen’) to a certain part of the body.

Ischaemic heart disease, is a condition wherein the body faces an inability to provide oxygen to the heart muscles. A very common end result of this condition is a myocardial infraction (Cardiac arrest or heart attack).

The causes for Ischaemic heart disease is still unknown. Although, there are a lot of probable theories, a concrete cause of this disease has not been narrowed down. There are a lot of factors that pose risk of this disease, controlling these has shown favorable results in preventing the disease. These factors are family history of coronary artery disease, diabetes, high blood pressure or atherosclerosis, smoking, poor nutrition especially a fatty diet, previous heart attack or stroke, overweight, hypertension, elevated cholesterol and/or low level of HDL (high-density lipoprotein). Genetic factors like family history of the disease cannot be avoided hence, it’s obvious that the individual will need to maintain a healthy lifestyle from all the other aspects to do their best to keep this disease at bay.
