Study Notes
Overview of Cardiovascular Disorders
- Leading cause of death in the United States, encompassing all heart and blood vessel-related diseases.
- Atherosclerosis, leading to narrowed and clogged arteries, is a key contributor to cardiovascular disease (CVD).
- Major contributors to atherosclerosis: elevated blood cholesterol levels and immune response.
Risk Factors for Coronary Heart Disease (CHD)
- Non-modifiable: Increasing age, male gender, family history of premature heart disease.
- Modifiable: High LDL cholesterol, low HDL cholesterol, hypertension, diabetes, obesity, physical inactivity, cigarette smoking, and poor diet high in saturated fats.
The Impact of Cigarette Smoking
- Smoking damages endothelial cells, promotes plaque formation, and raises LDL cholesterol.
- Passive smoking has similar negative cardiovascular health effects as active smoking.
- Smoking tightly linked to increased cardiovascular events.
Cholesterol Management Strategies
- Phytosterols: Plant-derived substances that help lower LDL cholesterol absorption in the intestines; sources include fruits, whole grains, and beans.
- Viscous Fibers: Soluble fiber from oats, barley, and legumes that binds bile acids to increase cholesterol excretion.
- Soy Protein: May reduce LDL cholesterol and is found in soy products, providing all essential amino acids.
- High-Protein Diets: Debated on their CVD impact; moderate fish consumption recommended to improve heart health.
Fatty Acids and CVD
- Dietary fats influence LDL and HDL cholesterol levels differently:
- High saturated fatty acids increase LDL cholesterol.
- Polyunsaturated fats reduce LDL cholesterol.
- Trans fats raise LDL while decreasing HDL cholesterol.
- n-3 Polyunsaturated fatty acids (found in fish) help in CVD prevention by lowering triglycerides and inflammation.
Therapeutic Lifestyle Changes (TLC)
- Recommended for individuals with CHD or multiple risk factors, emphasizing dietary and lifestyle changes to lower LDL cholesterol.
- Individualized LDL cholesterol goals and therapies based on personal risk assessments.
Nutrition Therapy for Hypertriglyceridemia
- Key approaches: Control body weight, physical activity, restrict alcohol, limit refined carbohydrates.
Hypertension
- Major risk factor for atherosclerosis, stroke, and kidney failure, impacting about one-third of U.S. adults.
- Treatable through weight management, the DASH diet, and regular physical activity.
Lifestyle Modifications to Manage Hypertension
- Weight reduction can significantly lower blood pressure.
- The DASH diet focuses on increasing fiber, potassium, magnesium, and calcium while reducing sodium intake.
Benefits of Regular Physical Activity
- Engaging in aerobic activities improves multiple CHD risk factors: lowers triglycerides, boosts HDL cholesterol, reduces blood pressure, promotes weight loss, and enhances heart function.
- Recommended at least 30 minutes of moderate-intensity activity most days, with a higher target for weight loss.
Metabolic Syndrome
- Defined as a cluster of conditions including abdominal obesity, insulin resistance, dyslipidemia, and elevated blood pressure.
- Waist circumference is crucial for diagnosis; the main goal is to reduce CVD risk.
- Diagnosed when at least three out of five criteria are met, including high waist circumference, elevated blood pressure, high triglycerides, and low HDL cholesterol.
