Which of the following are risk factors for cardiovascular disease? select the three correct answers.

a. high cholesterol
b. family history
c. tobacco use
d. sleep deficiency

A. High cholesterol

B. Family history

C. Tobacco use

Explanation:

High cholesterol :

Cholesterol accumulates primarily in the inner wall of blood vessels, specifically in the arteries, and especially in the coronary arteries, which supply the lower limbs and even in the arteries that supply the brain. There, that deposit produces an inflammation and consequent fibrosis, which in turn creates a plaque that can clog the arteries.  When this obstruction occurs partially at the level of the arteries of the heart, the symptoms presented by the patient are those of an angina - chest pain especially when we make efforts although it can also appear at rest. But if it is a total obstruction of acute form it can cause an acute myocardial infarction

Family history:

People with a family history of coronary heart disease (proven medical history and in an age below 55 in men and in women 65) the risk of having a cardiovascular disease is approximately the double.

Tobacco use:

Nicotine and carbon monoxide promote damage to arterial walls and thrombus formation and increase cholesterol levels. In addition, carbon monoxide decreases the oxygen supply to the heart. Not forgetting, moreover, that this damage extends to passive smokers.
