CAD Risk factors

Modifiable: increased serum lipids, high BP, tobacco use, diabetes w/ elevated blood glucose, obesity, & sedentary lifestyle

Non-modifiable: age, gender, heredity, & ethnicity

Other: stress, sex hormones, birth control pills, excessive alcohol intake, & high homocysteine levels

1

Arteriosclerosis

Abnormal thickening, hardening, & loss of elasticity of arterial walls

Accompanies CAD

2

Angina Pectoris

"Angina"- chest pain: results when the demand for O2 by the myocardial cells exceeds the supply delivered

Most common symptom of CAD

Stable, unstable, & variant

3

Stable vs Unstable Angina

Stable- "chronic" or exertional angina: occurs w/ exercise or activity & usually subsides w/ rest

Unstable- crescendo or preinfarction angina: occurs @ rest or w/ minimal exertion. Often not relieved by nitro, or requires more nitro administration, & unpredictable

4

AMI (acute myocardial infarction)

Death of myocardial tissue as a result of prolonged lack of blood & O2 supply

Cardiac rehab: patient teaching- exercise, medications, cessation of smoking, & diet
❎ Phases of cardiac rehab: inpatient management, telemetry monitoring during exercise, unmonitored rehab, & maintenanc

5

Right vs Left sided HF

HF: inability of the heart to meet the metabolic demands of the body
❎both sides fail as pumps

Left: usually fails first

Right: fails as a result of left sided HF

6

CMP (cardiomyopathy)

Progressive & chronic heart muscle disease

NKC- usually leads to HF

Dilated, hypertrophic, & restrictive

7

IE

Microbial infection of the endocardium that affect primarily the valves

Problem has increased w/ IV drug abusers

Patients w/ known valvular disease are @ risk for IE

Patients should be treated prophylactically before dental or invasive procedures

8

Mitral Stenosis

Narrowing of the opening in the mitral valve that impedes blood flow from the LA to the LV. Valve leaflets become thickened & fibrotic.

❎Rheumatic heart disease is the leading cause
