Diastolic heart dysfunction
• I am 53 years old, and I have been diagnosed with diastolic heart weakness, what is it? And what do you recommend?

> This is a summary of your questions. According to the reading of the cardiac ultrasound scan report that I sent, all heart chambers are normal in size, and so are all heart valves in normal shape and function. And that the force of contraction of the heart to pump blood is normal. But the report of the test result indicates the presence of a first stage of decreased ability of the heart to relax and expand to absorb blood. And diastolic weakness means that the left ventricle of the heart cannot expand and expand enough to accommodate the blood coming to it, meaning that it is considered a problem with “filling” and not in its “pumping” capacity.
As for the thyroid gland analysis, it is normal according to the test result you sent.
If you have been told by your attending physician that you suffer from this dysfunction of diastolic heart failure, it is important for you and your doctor to develop a treatment plan to prevent any symptoms you have because of this diastolic weakness, and to control them if they appear to you.
The best strategy for dealing with this diastolic dysfunction is to try to identify the cause or causes that contribute to it, and address it.
There are many factors that contribute to the development of diastolic dysfunction, some of which work together to increase the severity of this dysfunction. Among the most important of them is living a lifestyle that is not full of activity and physical movement, that is, lethargy and physical laziness in daily life. Note that a daily program of exercise can improve the diastolic function of the heart. In fact, aerobic aerobic exercise, such as brisk walking, jogging and swimming, is a behavioral therapy that has been shown to improve the quality of life for people with diastolic dysfunction, so it is very useful to talk about this with your treating doctor.
Other reasons for the emergence of a diastolic heart failure include the presence of heart rhythm disturbances, such as atrial fibrillation, the presence of high blood pressure in an uncontrolled condition with the return of blood pressure to normal rates, the presence of obesity, the presence of uncontrolled diabetes, and the presence of disorders in the sequence Breathing during sleep, and the presence of arterial disease.
Therefore, follow-up with the doctor is useful and necessary to try to find out the cause of the emergence of diastolic heart failure. If one of its causes is identified, it is worth treating.
Implementing all the following steps is important:
– Practicing healthy behaviors in daily life, such as exercising daily and abstaining from smoking.
Reducing body weight to keep it within normal rates by eating healthy meals.
Treating the cause and mitigating its negative impact on the diastolic abilities of the heart muscle.
It is also useful to follow up with the doctor to receive treatments that alleviate the symptoms of this diastolic weakness and prevent it from developing into the advanced degrees of it, i.e. the second, third and fourth degrees. Here, that is, in the first stage of diastolic weakness, the doctor may prescribe diuretic drugs to relieve congestion in the blood vessels, especially the blood vessels in the lungs. Depending on your health condition, he may also prescribe medications to control the heart rate to give the left ventricle a time break to absorb the blood coming into it.
I reiterate that daily physical exercise, reducing body weight, and therapeutic control of the causes of diastolic weakness are the most important therapeutic steps that should be initiated.
Antioxidants and Selenium
• Why is it important to take antioxidants or selenium?
Ruler of Ziyad – Medina
> This is a summary of your questions about the health benefit of taking antioxidants, is selenium one of them, as well as the health benefit of taking it and the necessary dosages for the body.
To begin with, and according to the NCCIH definition of alternative medicine, prescribing antioxidants includes many natural or manufactured substances that may prevent or delay the occurrence of some types of cell damage processes in the body. These include a number of vitamins, such as vitamins C and E, and a number of vegetable product pigments, such as lycopene carotenoids (in tomatoes and watermelons), lutein (in vegetables and many types of colorful fruits), zeaxanthin (in corn and pumpkin), and a number of minerals such as selenium. Therefore, natural vegetables and fruits are rich sources of different types of antioxidants.
There is good scientific evidence that making sure to eat a lot of vegetables and fruits is a healthy behavior, and that research has shown that people who eat more vegetables and fruits have a lower risk of many diseases. However, it is not scientifically clear whether these results are related only to the amount of antioxidants in the vegetables and fruits eaten, or also because of the presence of other healthy components in these foods such as fiber, minerals and natural vitamins, for example, or because of the presence of other health effects of mixing natural fruits and vegetables in the diet. The daily.
In contrast, careful scientific studies that examined the feasibility of taking antioxidant supplement preparations (capsules or tablets) in the prevention of chronic diseases, such as cardiovascular disease, cancer and cataracts, have not proven in most cases the reduction of antioxidants in these industrial preparations (not natural). In vegetables and fruits) from the risk of contracting these diseases, according to what is indicated by the US National Center for Complementary and Integrative Health. He adds that taking high-dose antioxidant supplement preparations may be linked to health risks in some cases. Also, some types of antioxidant supplement preparations may interact negatively with some medications that a person may take on a daily basis to treat their chronic conditions.
The potential biological mechanism for antioxidant viability may be related to both free radicals and oxidative stress. To clarify, free radicals are very unstable molecules that are naturally formed in the body’s tissues upon daily physical exertion as a result of energy production processes. Free radicals may also be formed when the body is exposed to a number of environmental influences, such as cigarette smoke, air pollution, and sunlight.
The accumulation of free radicals in tissues (high and for prolonged periods) may cause a state of oxidative stress that places its burden on cells, which may accelerate their damage. There is a medical belief that oxidative stress plays a role in the occurrence of a variety of diseases, including cancer, heart disease, cholesterol accumulation in the arteries, diabetes, Alzheimer’s disease, Parkinson’s disease and a number of eye diseases. Given this situation, antioxidants have proven their ability to withstand oxidative stress in laboratory experiments. But there is a medical debate about whether consuming large quantities of antioxidants (in the form of preparations) safely benefits health, while this is not the case with an increase in the intake of natural vegetables and fruits as natural and rich sources of antioxidants.
As for the mineral selenium, the daily need for the body of it is about 60 micrograms per day, for male and female adults or adolescents, as well as pregnant and lactating women. For young children over the age of six, it is approximately 25 micrograms. But in cases of selenium deficiency in the body, which are diagnosed by the doctor, the treatment depends on the doctor’s evaluation of the extent of the deficiency according to the result of the analysis.
