Acute congestive heart failure, OCH is a polyethological syndrome, in which deep violations of the pumping function of the heart occur.
The heart loses the ability to provide blood circulation at the level necessary to maintain the functioning of organs and tissues.
Let's take a closer look at the classification of acute heart failure.
- 1 Basic views
- 1.1 Left ventricular
- 1.2 Right ventricular
- 2 Classes according to KIPL
- 3 By clinical severity
The main types of
In cardiology, several methods are used to classify the manifestations of acute cardiovascular insufficiency. According to the type of hemodynamic disorders, distinguishes congestive and hypokinetic acute heart failure ( cardiogenic shock).
Depending on the localization of the lesion, the pathology is subdivided into right ventricular, left ventricular and mixed( total).
In cases of lesions of the left ventricle in a small circle of blood circulation, stagnation forms. Pressure in the pulmonary artery system increases, with increasing pressure, pulmonary arterioles narrow. External breathing and oxygenation of the blood are difficult.
The liquid part of the blood begins to sweat out into the lung tissue or into the alveoli, interstitial edema( cardiac asthma) or alveolar edema develops. Cardiac asthma is also a form of acute insufficiency.
Difficulty in breathing is manifested by shortness of breath, increasing to choking, in some patients Cheyne-Stokes breathing( intermittent breathing with periodic stops).
In prone position, shortness of breath increases , the patient tries to sit( orthopnea).In the early stages in the lower parts of the lungs, wet rales are heard, which turn into small bubbles.
Increasing obstruction of small bronchi is manifested by dry wheezing, prolonged exhalation, symptoms of emphysema. Alveolar edema is indicated by sonorous wet rales over the lungs. In the severe stage, the patient's breathing becomes bubbling.
The patient suffers from a dry cough , as the pathological condition progresses, sparse sputum separates into foamy sputum. Sputum can be colored pink.
BP values remain within normal limits or fall .The left ventricular form develops as a complication of coronary heart disease, myocardial infarction, aortic malformation, arterial hypertension.
Acute right ventricular failure develops with pneumothorax, decompression sickness, embolism of the trunk or branches of the pulmonary artery, total pneumonia. When the right ventricular function is disturbed, congestion forms in a large circle of circulation. The patient develops shortness of breath, on inhalation noticeably swelling of the jugular veins.
The liver enlarges and thickens due to blood stagnation in the portal system, it becomes painful.
There is an abundant cold sweat, acrocyanosis and peripheral edema appear.
As the disease progresses, the swelling spreads higher, the effusion of the liquid part of the blood into the abdominal cavity begins - ascites.
Some patients have abnormal stomach function - develops congestive gastritis .AD sharply decreases until the development of cardiogenic shock. In response to the progressive shortage of oxygen in the tissues, the frequency of respiration and palpitation increases.
Classes by Killip
The classification is based on the clinical manifestations of pathology and its radiographic signs. Based on these data, four stages of pathology are identified according to increasing severity:
- I - signs of heart failure do not appear;
- II - wet rhonchuses are heard in the lower parts of pulmonary fields, signs of pulmonary circulation are manifested;
- III - wet wheezing is heard in more than half the pulmonary fields, marked pulmonary edema;
- IV - cardiogenic shock, signs of narrowing of peripheral vessels, cyanosis, systolic blood pressure lowered to 90 mm Hg. Art.and below, perspiration appears, impaired excretory function of the kidneys.
Based on the clinical severity of
. It was proposed in 2003 to assess the condition of patients with acute decompensation of chronic heart failure. The basis is based on the symptoms of peripheral circulatory disturbances and auscultatory signs of stagnant phenomena in a small circle. Four classes of severity of the condition are distinguished by these criteria:
- I - stagnation is not detected, peripheral blood circulation is normal. The skin is dry and warm.
- II - symptoms of blood stagnation in the pulmonary lobe are revealed, there are no visible signs of venous outflow disturbance. The skin is warm and moist.
- III - Deficiency of peripheral circulation without concomitant disturbance of venous outflow in a small circle is determined. The skin is dry and cold.
- IV - signs of peripheral circulatory failure accompanied by congestion in the lungs.
Several clinical variants of the pathology pathology are possible:
- Decompensated , develops as a complication of a chronic form of pathology or for other reasons. Symptoms and complaints of the patient correspond to a typical clinic of a moderate OSN.
- Hypertensive heart failure .The blood pressure is greatly increased with relatively preserved function of the left ventricle. X-ray images show no signs of pulmonary edema. Symptoms and complaints of the patient are typical for OCH.
- Pulmonary edema .It is manifested by irregularities in the rhythm and frequency of breathing, the lungs hear rales, orthopnea, gas exchange in the lungs is difficult. X-ray images confirm the accumulation of fluid in the lungs.
- Cardiogenic shock .The extreme manifestation of the syndrome of small cardiac output. Systolic blood pressure decreases to critical values, the blood supply of tissues and organs is severely impaired. The patient exhibits symptoms of progressive renal dysfunction.
- Syndrome of increased cardiac output .It is accompanied by manifestations of blood stagnation in a small circle of blood circulation. The limbs of the patient are warm, possibly lowering blood pressure.
- Right-ventricular .The volume of cardiac output is lowered, pressure in the arterial bed is increased. Increased pressure in the jugular veins, stagnation in the portal system of the liver leads to the development of hepatomegaly.
Any possible classification is to some extent conditional and is designed to simplify the diagnosis and selection of treatment tactics in emergency situations.
