How to recognize signs of heart failure

Heart failure annually takes many lives. Doctors believe that this pathology is leading among the causes of mortality in humans. In this case, doctors say that some tragedies can be avoided. If a person who is able to recognize the signs of sudden cardiac arrest and who knows how to give help is found to be unfortunate, the patient is often able to reanimate.

So, why does the “main motor” stop occur? What are the symptoms to determine the impending problem? How to help yourself or another person?

Why stop
The human heart is a muscular organ. It consists of four hollow chambers (two atria and two ventricles). The body operates on the principle of a pump. A healthy heart works constantly, ensuring blood circulation throughout the body.

Cardiac arrest is a clinical syndrome in which the natural functioning of the heart suddenly stops. Discharge function is violated. The heart is not able to push blood into the arteries. The circulation stops. Organs do not receive the necessary nutrition. The brain suffers first. There is a serious threat to the life of the patient. The cells of the organs die off. The bill goes on for minutes.

Stop mechanism
If we consider the mechanism of cardiac arrest, then the reasons for this process lie in a sharp change in the functionality of an organ (especially in automatism, conduction and excitability).

At the first signs of heart attack, you need to see a doctor.
The work of the heart may stop for the following reasons:

Fibrillation. This problem is observed in almost 90% of all cases. Pathology is the asynchronous contraction of various sections of the myocardium. Such havoc in the ventricles blocks the release of blood from them. All organs begin to suffer from hypoxia. If fibrillation affects only the atria, then the impulses are able to reach the ventricles. In this case, the circulation continues. A short-term attack can pass on their own. Long-term tension of the ventricles excessively depletes the resources of the heart. It stops him.
Asystole. Rare reason. It is diagnosed in 5% of cases. In this case, the ventricles against the background of relaxation (diastole) completely stop contracting. To provoke asystole can oxygen starvation.
Causes of pathology
Doctors know many reasons that can provoke cardiac arrest. Among them may be cardiac pathology. But sometimes the stoppage happens even in those people who have never experienced heart failure.

Heart disease
Pathology may occur in the background:

coronary heart disease;
pathologies of the coronary arteries (eg, spasms, thrombosis);
embolism (blockage of blood vessels);
angina pectoris;
myocardial infarction;
arrhythmias;
myocarditis (infectious heart disease);
cardiomyopathy;
endocarditis;
cardiac tamponade (accumulation of fluid that prevents natural contractions).
Pathology can occur due to any heart disease.
Common causes
To provoke a cardiac arrest can:

intoxication of the body (with the abuse of alcohol, drugs, harmful chemicals);
severe dehydration;
injuries, injuries;
suffocation;
the impact of electric current on the body;
sharp blows, falling;
obstruction of the respiratory system;
pain shock;
respiratory failure;
drowning;
allergic shock;
severe bleeding leading to shock;
apnea;
cooling the body.
Drugs that cause stopping
Some drugs can have a disastrous effect on the work of the human “motor”. Usually such cases occur on the background of an overdose or with the wrong combination of drugs.

To stop can lead:

antiarrhythmic drugs;
drugs for anesthesia;
barbiturates;
psychotropic drugs;
narcotic analgesics;
a combination of some antiarrhythmic drugs and calcium antagonists.
Psychotropic drugs can trigger a heart attack.
Risk group
The risk to face cardiac arrest increases in people who:

abusing smoking;
have a genetic predisposition;
addicted to alcohol;
broke the 50-year mark;
experiencing serious overloads (faced with stress, practicing excessive physical exertion);
are obese.
Clinical picture
All signs characteristic of cardiac arrest are always pronounced. They can not be overlooked. Moreover, the symptoms increase very quickly. Therefore, to act in such a situation should be immediately.

What’s happening
Clinical death develops in the following stages:

There is dizziness. The patient experiences sudden weakness. There is a feeling of fear.
After 10 seconds, at most 20, a person loses consciousness.
It takes another 15-30 seconds, and there are characteristic convulsions.
Weak breathing is accompanied by wheezing. Gradually, it begins to subside.
Cyanosis occurs on an overly pale face. Blue lips, nose. Cyanosis covers the tips of the fingers, earlobes.
Pulse is absent. Beats are not heard in the carotid artery.
