V.Kh. Vasilenko (1935).

Stage I: initial or hidden.

It appears only during physical exertion, there are no stagnant phenomena ..

1. signs of fatigue (shortness of breath, sweating, finger tremors, cyanosis of the tip of the nose and lips);

2. slow recovery of the patient's initial state (more than 10 minutes after exercise);

3. with percussion of the heart, its increase is detected;

4. with palpation of the pulse and auscultation of the heart, tachycardia, cardiac arrhythmias, the presence of noise are determined;

5. increased fatigue during physical exertion.

Stage II: severe or prolonged.

Circulatory failure, not only during exercise, but also at rest.

1. a persistent decrease in stroke and minute blood volume;

2. an increase in the volume of circulating blood;

3. increased venous pressure, venous congestion in both circles of blood circulation, a change in water-salt metabolism;

Period IIA: stagnation mainly in the small or large circle

1. shortness of breath;

2. acrocyanosis;

3. transient, not very pronounced swelling of the legs and feet;

4. the size of the heart is increased, tachycardia is observed, sometimes arrhythmia;

5. a slight increase in the liver. On palpation in the right hypochondrium, the liver is painful, protrudes from under the costal margin by 2-3 cm;

6. single wet rales in the lower parts of the lungs;

7. in X-ray photographs - strengthening of the pulmonary pattern and roots of a lung of a stagnant nature.

Period IIB: congestion in both circles of blood circulation;

1. shortness of breath at rest (patients occupy a sitting position);

2. significant acrocyanosis;

3. massive swelling of the legs and feet;

4. the development of atrial fibrillation, often a tachyarrhythmic form; heart sounds are deaf, heart sizes are increased;

5. the liver is large, dense with a rounded or pointed edge, painful on palpation, protrudes from the costal margin by 6-10 cm;

6. ascites;

7. moist rales in the lower parts of the lungs and compaction of the roots of the lungs;

8. less commonly, hydrothorax and hydropericardium;

9. oliguria, high density of urine;

10. significant congestion in the organs;

11. severe hemodynamic disturbances;

Stage III: final or dystrophic

1. all the signs of period II B

2. exhaustion of patients (cardiac cachexia);

3. the skin is pale, flabby, pigmentation and trophic changes in the skin and subcutaneous tissue of the legs, significant acrocyanosis;

4. anasarca;

5. significant changes and metabolic disorders, hemodynamics;

6. dense edema (ascites, hydrothorax, hydropericardium);

31

7. an increase in heart size - cardiomegaly;

7. heart sounds are weakened or deaf, the heart rate is often incorrect - tachycardia, atrial fibrillation;

7. cardiac fibrosis of the liver (the liver is dense, enlarged, the edge is pointed, slightly painful, protrudes from the hypochondrium by 8-10 cm;

7. nephroangiosclerosis;

8. severe dysfunction of the endocrine system and c.n.s;

7. patients occupy a forced position (sedentary or half-sitting) due to severe shortness of breath at rest.

Classification Comments

Stage 0 CHF in the classification is absent, because in the absence of symptoms and heart damage, heart failure in a patient is simply not. Asymptomatic LV dysfunction already corresponds to the 1st stage of the disease or, according to the severity of symptoms, to 1st FC.

1. To determine the stage of heart failure, as it was in the classification of V.Kh. Vasilenko and ND Strazhesko, as well as to determine FC of heart failure, as is customary in the classification of the New York Heart Association (NYHA), special procedures and studies not required.

2. To objectify FC CHF, an application is given with the determination of the distance of a 6-minute walk.

Determining the distance of a 6-minute walk.

This method is widely used in the last 4-5 years in international practice and allows you to assess the patient's tolerance to physical activity, using minimal technical means. Its essence is that you need to measure what distance the patient is able to go within 6 minutes. This requires only a watch with a second hand and a tape measure. The easiest way is to pre-mark the hospital corridor and ask the patient to move along it for 6 minutes. Each FC of CHF corresponds to a certain 6-minute walk:

The severity of CHF:

• 551 m - no heart failure

426-550 m - I FC

301-425 m - II FC

151-300 m - FC III

<150 m - IV FC

Pic 3.5 Total heart failure.

1 - significant swelling of the legs and lower back;

2 - ascites;

3 - severe acrocyanosis;

4 - swelling of the cervical veins;

5 - swelling of the scrotum and penis.

The patient occupies the position of orthopnea.
