A 53 years old man, without medical history or drug use, shows up in the family physician’s room and makes an anxious impression. His friend has recently suffered from myocardial infarction (MI) and he is worried that he might also face the same situation soon. As for family medical history, he has a father with hypertension and an uncle with diabetes mellitus. He doesn’t seem to have any symptoms or complaints at this moment, but he has been smoking for 25 years and is overweight. Due to these characteristics he is worried of having a high risk of getting a MI. During the physical examination, his BMI was 29, RR was 152/90 mmHg and heart rate was 75 bpm. The family physician orders a blood test for lipid profile and glucose. Both turn out to be in the normal range. <br /> | A 53 years old man, without medical history or drug use, shows up in the family physician’s room and makes an anxious impression.

The family physician gives the patient several advices concerning primary prevention for atherosclerosis; quit smoking, try to achieve weight reduction, do regular physical activity, restrict alcohol consumption to <10-30g/day and follow a varied and balanced diet. Regarding the hypertension, the advice is to keep his RR under 140/90 mmHg. Antihypertensive medication is not indicated at this moment, because his 10-years risk of death due to cardiovascular diseases (Systematic COronary Risk Evaluation) is lower than 20%. He is advised for regular checkups of cardiovascular risk profile or report to the doctor’s office in case of chest pain.<br /> | The family physician gives the patient several advices concerning primary prevention for atherosclerosis; quit smoking, try to achieve weight reduction, do regular physical activity, restrict alcohol consumption to <10-30g/day and follow a varied and balanced diet.

Since the 20th century, cardiovascular diseases (CVD’s) have grown to be the leading cause of death and disability in the world, illustrated by 17.3 million deaths per year in 2008. Out of all cardiovascular diseases, coronary heart disease (46% among males, 38% among females) and cerebrovascular disease (34% among males, 37% among females) are accountable for the largest proportion of CVDs. In 2008, heart attack and stroke were responsible for 7.3 million deaths and 6.2 million deaths subsequently. Obstructive coronary and cerebrovascular disease are caused in most instances by atherosclerosis. It is a life-time illness that over time can eventually lead to obstructive disease. Once atherosclerotic lesions become clinically significant, serious acute complications such as ischemic heart disease, MI and stroke may occur. This chapter concerns the complex pathological process of atherosclerosis, possible consequences of atherosclerosis and the most recent treatment for atherosclerosis in order to prevent CVD’s. <br /> | Since the 20th century, cardiovascular diseases (CVD’s) have grown to be the leading cause of death and disability in the world, illustrated by 17.3 million deaths per year in 2008.
