What is diastolic dysfunction of the left ventricle 1 type?

Diastolic dysfunction of the left ventricle 1 type - what kind of disease is it, and how should it be treated? The answer to this question will be given in the materials of the article presented. In addition, you will find out why such a pathological condition occurs, and by what obvious signs it can be identified.

general information

Before answering the question about why diastolic dysfunction of the left ventricle of type 1 arises, it is necessary to find out what the organ is.

The left ventricle is one of the four chambers of the human heart . It is in it that the blood circulation (a large circle) that starts a continuous flow of blood in the body begins.

What kind of disease?

The diastolic dysfunction of the presented part of the heart is a significant decrease in its ability to distill blood into its cavity from the pulmonary artery. In other words, such a pathological condition leads to the impossibility of ensuring normal blood circulation.

Thus, diastolic dysfunction of the left ventricle 1 type is a serious heart disease, which is characterized by the inadequate ability of the part of the body to relax during diastole. It should be specially noted that it can take about 0.4 seconds. This time is quite enough to completely restore the tone, as well as the energy fullness of the heart muscle.

What is dangerous disease?

Diastolic dysfunction of the left ventricle of type 1 is caused by the fall of the ejection fraction, which subsequently leads to a marked decrease in the stroke volume. To prevent stagnation of blood in the lungs and to compensate for dilatation, the systolic volume of the ventricle begins to increase. If such a protective reaction of the body does not follow, then there is a clear threat of pulmonary hypertension (repeated), and the load on the other ventricle (right) increases significantly, which subsequently leads to a decrease in its volume. As a result of diastolic pressure , venous hyperemia can occur in it. If there is acute dysfunction, then pulmonary edema develops easily.

Probable causes

Why can diastolic dysfunction of the left ventricle 1 type develop? The reasons for this phenomenon lie in the following:

• Hypertensive pathologies;
• Hypertrophic cardiomyopathy ;
• Infiltrative (periodic) heart lesions (i.e., infarcts, ischemic heart disease, chronic hypertension (arterial), and hypertrophy of individual cardiac segments that are outside the dilatation and thinning zone).

Evidence of deviation

This condition very often leads to the development of secondary pulmonary arterial and venous hypertension. This pathological condition can be manifested in the following:

• A persistent cough (often paroxysmal);
• Night dyspnea (paroxysmal);
• dyspnea.

By what other signs is diastolic dysfunction of the left ventricle of type 1 determined? Symptoms of such a deviation may a large amount of time in no way manifest themselves. However, with the development of the disease, patients begin to observe such signs as:

• Regular heart pains, which are of a paroxysmal nature (as in ischemic disease);
• Swelling of the lower extremities;
• Shortness of breath (can be observed even at rest);
• Spastic phenomena;
• Feeling of shortage of air.

At such signs it is necessary to address for consultation to the attending physician. The sooner this pathological condition is revealed, the easier it is to take it under control. If the presented disease is detected too late, then its treatment will last a very long time, with the use of a large number of drugs and all the necessary procedures.

How to cure?

Currently, there is no single therapy scheme that would be recognized by most specialists. In part, this is due to the fact that the given disease is not easily diagnosed. As it was said above, such a deviation takes a very long time without symptoms, as a result of which the patient resorts to medical care too late.

So what if you have diastolic dysfunction of the left ventricle 1 type? Treatment of such a disease is reduced to eliminating the causes that provoke negative trends. Thus, patients need:

• Cure existing ischemia;
• To normalize the heart rate;
• Lower blood pressure.

Among other things, if a patient is diagnosed with this condition, preparations of the ACE blocker group are prescribed. Most often, the choice of specialists falls on Lizonopril. It is prescribed in the form of tablets of 20-40 milligrams per day (in two divided doses).

Good results in the treatment of this deviation can be achieved through the use of calcium blockers. Thus, both drug groups lower blood pressure, significantly reduce the need for cardiac tissue in oxygen, and also stop and reduce left ventricular hypertrophy. By the way, as a result of taking these medications, the work of the diastole of the heart improves, which subsequently leads to the normalization of hemodynamics.

The best results of treatment of such a disease were noted when a combination of potassium-sparing diuretics with cardiac drugs was observed. In case of acute need, other antihypertensive medications may be used.
