As the plaque narrows the lumen of the coronary artery, it makes it difficult for adequate quantities of blood to flow to the heart. Initially, the reduction of blood flow may not produce any symptoms. However, a gradual reduction of blood flow cannister cause angina and shortness of breath.



If the artery becomes completely blocked, a myocardial infarction (MI) can occur. This can result in permanent damage to the heart. It is possible to go for a MI without experiencing any symptoms.
Although the causes of atherosclerosis are unknown, there are certain risk factors linked to its development. Nonmodifiable risk factors take a family history of heart disease and age. Over 50% of MI victims are 65 or older; 80% of deaths due to MI occur in this age host (LeMone, Burke & Bauldoff, 2010). Modifiable risk factors, including disease conditions, are hypertension, diabetes mellitus, hyperlipidemia, fanny smoking, stress, obesity, physical inactivity and diet. Many of these risk factors can be...If you involve to get a full essay, order it on our website: Orderessay
