CVD MNT- Part 2
Cardiovascular Disease Medical Nutrition Therapy
What is the Anat/Phys of the Cardiovascular System?
Regulated blood flow to the tissues to deliver Oxygen & Nutrients
Retrieves waste products
Closed loop of blood vessels for which the heart acts as two pumps
What are the three layers of the heart?
What do the left/right sides of your heart do?
: Pumps blood with its oxygen load throughout the body
: Pumps blood through the LUNGS pulmonary circulation to pick up oxygen
What is Hypertension?
Chronic elevation of BO
Increases risk of CHF, kidney failure, MI, stroke, aneurysms, vision probs
What is an Aneurysm?
Weak area that bulges out/abnormality
What is the difference between systolic and dylostolic?
: Heart Contraction
: Heart Relaxation
What is the etiology of Hypertension?
Secondary- Result of another chronic condition (renal, alcoholic, overweight)
Hyperinsulinemia- To much insulin, apple shaped, metabolic syndrome
What does it mean it there is an increase in C-reactive PRO?
Inflammation somewhere in the body & an increased risk of hypertension
What is the pathophysiology of Hypertension?
Excessive secretion of vasopression % angiotensin II
Smoking (Decreases nitrious oxide- so blood vessels are restricted)
Renal Disease (increase Na retention and renin)
What are some diagnosis statements for PES?
excessive energy intake
Inadequate Ca, fiber, K, Mg
Overweight or Obesity
Lack of food related knowledge
What are some meds. for Hypertension?
Loop Diuretics:Inhibit Na abs, K reabs, increase prostoglandins,
: Inhibit reabs of Na, K, and Cl, as on distal tube
: Block enzymes that changes from angiotensin I to II causing dilated blood vessels
: Lower BP
Ca blocking agents
What is the DASH prescription per food group?
Veg 2-2.5 C.
Fruits 2-2.5 C.
Skim Milk 2-3 C.
Lean Meats 6oz or <
Nuts/Seeds, legumes 4-5oz/week
*fiber for wt. control
What is the nutrition prescription for hypertension?
Assess dietary intake
Meet DASH dietary goals
tailor exercise goals
Explain the process of CHD.
Injury to the lining of the artery (smoking, homocystine, inflammation)
Blood tried to repair damage
Monocytes burrow in the blood-vessel walls where they mature into macrophages
Macrophages consume oxidized fatty substances and die causing a buildup of tough fibrous scar tissue that can inhibit blood flow and promote clot formation
What can high levels of homocystine do? How can it be kept low?
It can contribute to the initial damage of the artery.
AI:Folacin, B6, B12
What is the diet impact on CHD?
A high fat diet can contribute to increase amounts of LDL available to be oxidized.
Lack of fruits/veg less anti-oxidants
What are the idea blood lipids?
: <100 DM <70
What is atherosclerosis/arteriosclerosis?
: Thickening of blood vessel walls caused by presence of plaque
: Includes loss of vascular elasticity
