Medical Video: Diastolic Heart Failure Treatment Study
In recent years, a new type of heart disease has been diagnosed by cardiologists, and the discovery of this new disease is called diastolic dysfunction. When diastolic dysfunction worsens, it can cause diastolic heart failure.
Although diastolic dysfunction or diastolic heart failure are considered 'new' - this condition has actually been around us for a long time. However, it is only about one or two decades, because the use of echocardiograph to diagnose heart problems causes these conditions to only become known in general.
The diagnosis of diastolic dysfunction is now widely made, especially for older women, many of whom are surprised to hear the fact that they have heart problems. And even though some patients begin to experience diastolic heart failure, others can still be avoided, especially if they get proper medical care and are able to treat themselves well.
Until now, almost all patients who come to the hospital with parts of acute heart failure, usually will develop diastolic heart failure. However, a diagnosis can trap us, because when a person has been diagnosed with diastolic heart failure, sometimes the heart will display its normal function in front of the echocardiograph - unless the doctor is able to see specifically and realize signs of diastolic dysfunction. For this reason, sometimes a diagnosis of diastolic heart failure can be missed or not noticed by certain doctors.
What is diastolic dysfunction and diastolic heart failure?
The heart cycle in a person is divided into two parts - namely systolic and diastolic. When the systolic phase, the ventricula (the part of the heart that functions to pump blood) contracts, so that it draws blood and flows it to the heart and arteries.
After the ventricula has finished contracting, they will rest. During this phase of relaxation, the ventricula will then fill it with blood and will prepare to do the next contraction process. This relaxation phase is called diastolic.
However, sometimes, due to certain medical conditions, the ventricula can become stiff. This rigid ventricula cannot fully rest, as a result the ventricula cannot be filled to its full potential and blood can be blocked in organs (especially the lungs). Abnormal conditions that occur in the ventricula and the results of abnormal filling of the ventricula during the diastolic phase are called diastolic dysfunction.
When producing diastolic dysfunction pulmonary congestion (stem blood before flowing into the lungs), this event is called diastolic heart failure.
In general, when doctors use the term diastolic dysfunction and diastolic heart failure, the doctor basically talks about isolated diastolic abnormalities. ("Systolic dysfunction is just another name for the weakening of the heart muscle, which can occur like an event of heart failure)
What are the causes of diastolic dysfunction?
Diastolic dysfunction can arise due to the following medical conditions:
- high blood pressure
- hypertrophic cardiomyopathy
- aortic stenosis
- coronary artery disease
- restrictive cardiomyopathy
- diabetes
- obesity
- aging
Symptoms of diastolic dysfunction and diastolic heart failure
Diastolic dysfunction alone sometimes does not show significant symptoms, unless it develops into diastolic heart failure. Symptoms experienced by people with diastolic heart failure are similar to symptoms in people who have heart failure.
With diastolic heart failure, signs of lung blockage include shortness of breath, coughing, and rapid breathing. Moreover, to see differences in the typical pattern of worsening respiratory problems in patients with heart failure, people with diastolic heart failure sometimes experience these symptoms as a sudden onset, usually occurring without warning. The sudden part of difficulty breathing is called "flash pulmonary edema“.
Flash pulmonary edema can occur when the main medical condition worsens, which can lead to a reduction in the diastolic function of the heart muscle. Sudden deterioration in diastolic function can cause sudden lung congestion.
Medical conditions that stimulate this acute part, including in it atrial fibrillation and other conditions of rapid heart rhythm, periods of high blood pressure (especially an increase in systolic blood pressure), and parts of cardiac ischemia. When part of severe lung congestion suddenly assessed as the main symptom of diastolic heart failure, patients with this condition can have difficulty breathing.
The study using echocardiograph detected that diastolic dysfunction appeared in 15% of the population under 50 years and 50% of the population above 50 years. Moreover, this disease usually affects women, because more than 75% of patients with diastolic heart failure are women.
When does diastolic dysfunction become diastolic heart failure?
Diastolic heart failure comes when patients with diastolic dysfunction experience severe pulmonary blockage, which is sufficient to show symptoms. If the diastolic heart failure occurs once, this is likely to occur again, especially because the treatment is not maximal.
