CAD Flashcards
Is the narrowing or blockage of the coronary artery, usually caused by atherosclerosis
Coronary Artery Disease (CAD)
Risk factors of CAD in Nonmodifiable Risk Factors
-Family history of CAD
-Age (> 45 years for men; 55 years for women)
-Gender: Men develop CAD at an earlier age
-Race: African American
Risk factors of CAD in Modifiable Risk Factors
-Hyperlipidemia
-Cigarette smoking, tobacco use
-Hypertension
-Diabetes
-Metabolic Syndrome
-Obesity
-Physical inactivity
Is an abnormal accumulation of lipid and fibrous tissue in the lining of arterial blood vessel walls
Coronary atherosclerosis
Involves a repetitious inflammatory response to injury of the artery wall and subsequent alteration in the structural and biochemical properties of the arterial walls
Coronary Atherosclerosis
Medical Management of Coronary Atherosclerosis
Goal: Prevent, modify, or slow progression of the disease
-Health Promotion
-Diet Therapy
-Physical Acitvity
-Drug Therapy
All adults 20 years and older should have a fasting lipid profile performed once every 5 years, and more often if the profile is abnormal
Fasting Lipid Profile
Preparation for Fasting Lipid Profile
NPO for 10-12 hours
Low-Density Lipoprotein (LDL)
<100 mg/dl (<70 mg/dl for very high risk)
Total Cholesterol
<200 mg/dl
High-Density Lipoprotein
> 40 mg/dl for males, >50 mg mg/dl for females
Triglyceride
<150 mg/dl
Diet Therapy
Therapeutic Lifestyle Changes (TLC) Diet
TLC Diet Characteristics
-Decreased consumption of saturated fat and cholesterol
-Increase in complex carbohydrates and fiber
Reduces risk of CAD when eaten regularly
Omega- 3 fatty acids
Without CAD:
Fatty fish (i.e., salmon, tuna) 2x a week as these contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)
With CAD:
EPA and DHA supplements together with diet
Intensity aerobic activity for at least 150 minutes per week
Moderate
Intensity aerobic activity at least 75 minutes per week
Vigorous
If weather is hot and humid:
-Exercise during the early morning, or indoors
-Wear loose-fitting clothing
If weather is cold:
-Layer clothing
-Wear a hat
Drug Therapy for Coronary Atherosclerosis
HMG-CoA Reductase Inhibitors Drugs
-Atorvastatin (Lipitor)
-Simvastatin (Zocor)
Therapeutic Effects of HMG-CoA Reductase Inhibitors
Decrease total cholesterol, decrease LDL, increase HDL, decrease TG
Drug Therapy for Coronary Atherosclerosis
Fibric Acids Drugs
Fenofibrate (Tricor)
Therapeutic effects of Fibric Acids Drugs
Increase HDL, decrease TG
Drug Therapy for Coronary Atherosclerosis
Bile Acid Sequestrants Drugs
Cholestyramine (Questran)
This drug is used as an adjunct therapy if statins alone are not effective in controlling lipid levels
Bile Acid Sequestrants
Therapeutic effects of Bile Acid Sequestrants Drugs
Decrease LDL, slight increase in HDL, oxidizes cholesterol into bile acids
A clinical syndrome usually characterized by episodes or paroxysms of pain or pressure in the anterior chest
Angina Pectoris
Etiology of Angina Pectoris
Coronary Atherosclerosis
Types of Angina
-Stable Angina
-Unstable Angina
-Intractable Angina
-Prinzmetal’s Angina
Characteristics of Stable Angina
PORN
-Predictable and consistent pain
-Occurs on exertion
-Rest
-NTG
Characteristics of Unstable Angina
-Symptoms increase in frequency and severity
-May not be relieved by rest and/or NTG
-Unstable: Up
Characteristics of Intractable Angina
-Severe, incapacitating pain
-Intractable: Incapacitating
Characteristics of Prinzmetal’s Angina
-Pain at rest
-Reversible ST-segment elevation
-Prinzmetal’s: Pain at Rest
Clinical Manifestations of Angina Pectoris
-Deep behind sternum (retrosternal area)
-Radiates to the neck, jaw, shoulder, and inner aspects of upper left arm
-Accompanied by apprehension and a feeling of impending death
-Feeling of weakness or numbness in the arms, wrists, and hands
-SOB
-Pallor
-Diaphoresis
-Dizziness
-N/V
Diagnostics of Angina Pectoris
-12-Lead ECG
-Treadmill Stress Test
-Dobutamine Stress Test
Reveals an inverted T-wave
12-Lead ECG
Medical Management of Angina Pectoris
Goal: increase oxygen supply while decreasing oxygen demand
-Oxygen therapy
-Drug Therapy
-Initiated at onset of chest pain
-Attempts to increase the amount of oxygen delivered to the myocardium and to decrease pain
Oxygen Therapy
