8. Arterial hypotension syndrome

Lowering blood pressure in arteries - systolic below 100 mm Hg. Art., diastolic - below 60 mm RT. Art. Distinguish between physiological and pathological arterial hypotension. A decrease in blood pressure can be observed in individuals of asthenic type, especially in an upright position (orthostatic hypotension). How a pathological symptom can be observed with shock and collapse, as a manifestation of heart or vascular insufficiency - with infectious diseases, intoxications, some lesions of the central nervous system, anemia. SYMPTOMS:

  • weakness, lethargy;

  • dizziness, fainting;

  • headaches, tinnitus;

  • visual impairment;

  • sometimes, cold sweat;

  • blood pressure below 100/60 mm Hg

  • pallor;

  • palpitations, tachycardia;

  • pulse of low voltage, filling.

9. Heart failure syndrome

FORMS:

  1. acute left ventricular (left atrial);

  2. acute right ventricular;

  3. chronic left ventricular (left atrial);

  4. chronic right ventricular;

  5. total, chronic, stagnant.

CAUSES: 1) diseases that cause dystrophy, necrosis, sclerosis, inflammation and myocardial hypertrophy: heart defects, hypertension, myocarditis, thyrotoxicosis, coronary heart disease, cardiomyopathy, myocardial dystrophy, etc. 2) diseases affecting the heart from the outside: diseases of the lungs, pleura, pericardium, etc.

BASIC SYMPTOMS the severity of all manifestations depends on the severity of heart failure:

  1. shortness of breath, often inspiratory. Sometimes as an equivalent - cough, hemoptysis;

  2. tachycardia;

  3. swelling, decreased urine output;

  4. acrocyanosis, cyanosis.

With left ventricular and left atrial (with mitral stenosis) heart failure - congestion is noted in the pulmonary circulation (inspiratory dyspnea, cough, hemoptysis, moist rales, in the lower parts of the lungs, and sometimes over the entire surface of the lungs, pink foamy sputum, orthopedic. manifestations - cardiac asthma, alveolar pulmonary edema.

Right ventricular heart failure is a congestive phenomenon in a large circle of blood circulation: enlarged liver, swelling in the legs, ascites.The symptom of Kussmaul is an increase in swelling of the cervical veins on inspiration.

Positive symptom of Plesha - is characteristic of severe biventricular or right ventricular failure, is an indicator of venous stasis, high central venous pressure and volume overload. When the patient is calmly breathing for 10 s, the palm is pressed onto the enlarged liver, which causes an increase in central venous pressure by approximately 4-5 cm of water. Art. and increased swelling of the cervical veins. An abdominal-jugular test can be performed, with palm pressure being applied to the anterior abdominal wall in the umbilical region (the abdominal press should not be stressed). The result of the sample is evaluated in the same way as with the hepatic-jugular Plesha test.

The severity of chronic heart failure is regulated by the classification of N.D. Strazhesko -
