Cardiovascular disorders - Answer-Cardiovascular disorders are prevalent in primary care. Many of
the disorders develop over several years, due to the risk factors to which individuals have been exposed.

What is Coronary Artery Disease (CAD)? - Answer✔✔-CAD is considered the leading cause of death in
the United States (U.S.). It is the result of longstanding atherosclerosis.
Atherosclerosis begins with damage to the endothelium. It is the endothelium, under normal functioning
that maintains balance between the vasoconstrictive and vasodilation actions, prevents platelets from
aggregating and control of the production of fibrin. When the endothelium becomes damaged, our
familiar inflammatory processes occur. Macrophages attach to the endothelium, setting up phagocytosis;
plaque formation and vasoconstriction also occurs marking the beginning of atherosclerosis. The plaque
lesions located in the vessels become enlarged which allows the plaque to progress within the enlarged
vessel lumen. The plaque lesion disrupts normal blood flow and causes thrombus formation which can
be triggered by cardiac risk factors such as elevated LDL, cholesterol, smoking and diabetes.
So, why is this a problem?
Well, the plaque takes decades to develop in the coronary arteries. With mild disease, blood flow can get
through the arteries and the patient is asymptomatic. Overtime, this build up can lead to narrowing
which results in decreased oxygen supply. When atherosclerosis reaches a clinically significant level, the
patient will begin to experience angina. Further progression of the disease will result in acute coronary
syndrome (ACS), formerly known as myocardial infarction (MI).
The major risk factor for the development of CAD - Answer✔✔-The major risk factor for the
development of CAD is family history. There is a 50% higher risk for individuals to develop heart disease
if they have a first degree relative (especially father) or sibling who has suffered from ACS or premature
