Acute heart failure symptoms before death

Acute heart failure occurs because of abnormalities that violate the heart muscle (myocardial infarction, severe arrhythmias). Appears this disease is severe symptoms, among which special mention should be made pulmonary edema, acute constriction of pulmonary vessels and cardiogenic shock (the latter the degree of insufficiency of the left ventricle in which the myocardium loses its ability to contract normally, and the tissues of the body adequately krovenapolnenia).

Reasons

OSN may develop on the background of various factors. The most common among them are:

  • myocardial infarction;
  • hypertensive crisis;
  • severe arrhythmia;
  • myocarditis;
  • a sharp narrowing of the aorta (stenosis);
  • cardiomyopathy arising after childbirth;
  • stroke;
  • infectious diseases;
  • bronchial asthma;
  • large-scale surgery;
  • kidney failure;
  • tumors;
  • anemia;
  • the abuse of alcohol;
  • overdose drugs, etc.

Right, DOS is much rarer than the left ventricular. Usually it is triggered by a mass blockage (embolism) pulmonary artery. Acute heart failure can occur because of asthma, myocardial infarction and rupture of aortic aneurysm into the pulmonary artery.

Classification and symptoms of AHF

According to the generally accepted classification distinguishes three stages of congestive heart failure. The first stage is called primary, or hidden. At this stage, the patient complains of shortness of breath, feeling of rapid heartbeat and heart palpitations after heavy physical exertion. When the person is not subject to physical or emotional stress, the General condition is satisfactory, the bodies correctly perform their functions, as it filled with blood. There is a slight decrease in disability.

Hypertension is no longer a disease?

Doctors are shocked by the statement, the chief cardiac surgeon in the country Leo Beaucaire.

In the second stage, doctors diagnose ongoing pronounced circulatory insufficiency, in which the small circle (the exchange of blood between the lungs and the heart), there is a stagnation even after a slight exertion or at rest. The second stage is divided into subgroups «A» and «B».

Subgroup «A» flows more calmly. Tachycardia and shortness of breath bothering the patient only after exercise. The examination detected some pallor and blueness of the skin. The patient complains of a dry cough without sputum or even hemoptysis. Examination reveals symptoms of stagnation processes in the lungs (e.g. quiet, wet rales in the lower parts of bodies) as well as tachycardia and arrhythmia. Under «A» are already starting to diagnose blood stasis not only in small but also in the systemic circulation. It is manifested by edema in the legs, mild enlargement of the liver. The symptoms are more pronounced in the evening, in the morning manifestations of the disease are less clearly visible.

When phase «B» shortness of breath begins to bother the patient and at ease, he complains of constant aching pain in the heart area, tachycardia and disability. Objective examination reveals a sharp paleness and lividity of the skin, congestion in the lungs. Due to the development of problems in the systemic circulation are observed unfading swelling of the legs and lower torso, a sharp increase and seal liver. In the pleural cavity accumulates fluid (hydrothorax), the same changes occur in the abdominal cavity (ascites). During the examination of the functions of the urinary system detects severe oliguria — low urine output (less than 500 ml at the rate of 1 – 1,5 l).

Last, the third stage is called «degenerative» or «final». Due to circulatory disorders symptoms begin to appear not only on the part of the cardiovascular system, cease to function normally all the organs. Irreversible changes in: liver cirrhosis (destruction of normal cells and their replacement by scarring), diffuse pulmonary fibrosis (proliferation of connective tissue in the lungs), congestive kidney (overflow in her blood). This stage is the last before the death, as treatment is ineffective.

First aid (PMP) with acute heart failure

Emergency DOS hard enough for people without medical education. Therefore, in the event of such symptoms should immediately call a medical team!

I forgot about hypertension forever!

Oleg Tabakov has shared his secret to a successful struggle with high pressure.

However, there are several ways to help the patient. So, until the arrival of the doctor should:

  • Reassure the victim and others, to ensure patient emotional peace.
  • To position the patient, to give him a comfortable position.
  • To lower the foot (if the victim is lying on the bed, you gently lift and seat with lots of pillows under the upper torso, neck and head).
  • To give Nitroglycerin tablets (2 – 3 pieces) sublingually (under the tongue) every 5 – 10 minutes until there will come a marked improvement: the patient will feel better, your skin will not be pale, it will be wheezing.
  • To follow irregular blood pressure, his decline is considered a favorable symptom.

The improvement in the patient after these activities for 5 – 15 minutes it begins to feel satisfactory. If these actions were not enough to relieve symptoms of congestive heart failure, you should just monitor the victim and await the arrival of the ambulance.
