HYPERTENSION AND HEART DISEASES

 


Heart Failure

Adults

 

Best time to refer to the dietician:

  • after diagnosis of heart failure class II, III or IV NYHA (New York Heart Association), which may be combined with unintended weight loss > 6% of the original weight in the last 6-12 months.

 

Relevant information for the dietician:

  • Diagnosis: heart failure + class, any comorbid conditions
  • Symptoms: edema, ascites, anorexia, dyspnea
  • Medication: diuretics, ACE-inhibitors, infusion fluids
  • Other: height, (changes in) weight, extent of fluid restriction.

 

Decision tree: Dietetic Diagnosis, Treatment and Care for Heart Failure

 

Determination of the diagnosis and treatment in dietetic care for heart failure

 

Goal and practice of dietetic care

Referral diagnosis, dietary prescription:

Restricted sodium, 2400 mg [3]

 

Or

 

Restricted sodium, 2000 mg [3] and restricted fluids 1500-2000 ml [4]

 

In combination with:

- Constipation [5]

 

 

One-time group patient education [14]

 

 

 

 

 

 

 

 

 

NYHA I, II and III [2]

 

Referral diagnosis, dietary prescription:

Restricted sodium, 2400 mg [3]

 

Or

 

Restricted sodium, 2000 mg [3] and restricted fluids 1500-2000 ml [4]

 

In combination with:

- Alcoholic cardiomyopathy [6]

- Unwanted weight loss [7]

- Cardiac cachexia [7]

- BMI < 30 [7]

- Obesity BMI > 30 [8]

- Acute and/or chronic renal insufficiency [9]

- Diabetes Mellitus [10]

- Hypercholesterolemia [11]

- Ileostomy [12]

 

Or, when the referring physician deems individual dietetic treatment necessary for the patient [13]

When there are problems in the practical application of sodium and fluid restriction [15]

 

 

If there is a change in the health status [15]

 

Individual treatment [16]

 

 

 

NYHA IV [2]

 

Referral diagnosis, dietary prescription:

Low sodium, 2000 mg [3] and fluid restriction 1500-2000 ml [4]

Aims of the diet:

  • reduce fluid retention
  • support blood pressure control
  • maintain/improve nutritional status.

 

Characteristics of the diet:

  • low salt: 2000-2400 mg. Distribute salt intake carefully over the course of the day; avoid sodium peaks.
  • fluid restriction: for NYHA class III and IV, not to exceed 1.5-2 L of total fluids (including infusion fluids)
  • Restricted sodium: 2000-2400 mg. Distribute salt intake carefully over the course of the day; avoid sodium peaks.
  • Fluid restriction: for NYHA class III and IV, not to exceed 1.5-2 L total fluids (including infusion fluids)
  • If diuretics are used which result in potassium excretion: ensure a sufficient intake of potassium.
  • If potassium-retaining diuretics are used in combination with ACE inhibitors: no potassium-rich salt-replacing mineral mixtures when serum potassium is > 5.5 mmol/L
  • Ensure sufficient energy
  • Alcohol intake according to national Nutritional Guidelines. Alcohol abstinence in the case of alcohol-induced cardiomyopathy.
  • Lifestyle recommendations:
  • smoking cessation
  • regular physical exercise
  • If BMI > 30 kg/m2: maintain/achieve a healthy body weight.

 

Treatment time:

  • Care level 2*, see “Dietician’s working methods.”

 

Specific remarks:

  • Edema and ascites may mask the weight loss.
  • Some medications, such as antibiotics and vitamin and mineral complexes, may contain sodium.

Hypertension

Adults

 

Best time to refer to the dietician:

  • when there is:
  • average (of 2 measurements) systolic blood pressure of 140 mm Hg or higher
  • use of antihypertensive medications.

 

Relevant information for the dietician:

  • Diagnosis: hypertension, any comorbid conditions
  • Symptoms: headache, dizziness
  • Medication: antihypertensive drugs, diuretics
  • Other: height, (changes in) weight, risk profile (overweight, smoking, excessive alcohol consumption, too little physical exercise, incomplete nutritional intake, use of medications, familial predisposition).

 

Aims of the diet:

  • reduce blood pressure
  • support antihypertensive medication

 

Characteristics of the diet:

  • based on national Nutritional Guidelines, with extra attention to:
  • low sodium diet, up to max. 2400 mg sodium
  • saturated fats: should account for 10% or less of total caloric intake
  • trans-fatty acids: < 1% of total caloric intake
  • 150-200 g vegetables and 2 servings of fruit per day
  • fish eaten twice weekly, one of which is a fatty fish (with low sodium)
  • alcohol according to recommendations (women a maximum of 1 standard glass and men a maximum of 2 standard glasses per day, spread out over the course of the week).
  • restricted glycyrrhizic acid
  • when potassium-retaining diuretics are being taken in combination with ACE inhibitors: no potassium-rich mineral mixtures when serum potassium is > 5.5 mmol/L
  • If diuretics are used which result in potassium excretion: ensure a sufficient intake of potassium in the diet.
  • lifestyle recommendations:
  • if overweight, see “Overweight”
  • adequate physical exercise
  • smoking cessation

 

Treatment time:

  • Care level 1, see “Dietician’s working methods.”

 

Specific remarks:

  • Restriction of sodium in the diet always results in lowering blood pressure; the effect seems greater in those who have elevated blood pressure, the elderly, blacks and overweight individuals.
  • The effect of a low salt diet depends on the individual sodium sensitivity. The greater the sodium restriction, the greater it seems to affect blood pressure.
  • Some effervescent tablets contain sodium.
