Есть ли надежда на решение проблемы с сердцем моей дочери?

The cardiologist would be the best person to consult if you are having any heart pain or chest discomfort or left arm. Your symptoms may be sign of a heart problem. It needs to be checked by a specialist physician. Please don't postpone your medical visit in these situations. 

Possible reasons for this can be anxiety or stress, heart-related issues, or musculoskeletal problems. A professional can evaluate your symptoms, perform a physical examination, and ask for further tests to determine the cause.

Please have a healthy lifestyle like eat healthy, do exercise daily, sleep well ,stop smoking and drinking if you do etc. Stay away from stress and tension to reduce your heart rates. You can also go to a cardiologist for discussing more treatments that can work for you. I hope this answer proved useful.

Without more information I can't say much. I feel you should talk to your doctor about it as he has more knowledge about your individual condition. He can guide you the best and clear all your doubts. Please let me know if you need any other help. Thanks.

Tightness in the chest may be associated with arm and back pain pointing to a heart disease – either angina or heart attack. Please do not hesitate and get medical attention if these symptoms persist. Please visit a cardiologist

The absence of a left superior vena cava is a rare anatomical variation where the vein is not located in its usual position. It is generally considered a normal variant and not inherently good or bad. While it usually doesn't cause health issues, it can bring challenges during certain medical procedures.

You have an echogenic focus measuring 2.9 mm in the left ventricle - this is often a meaningless discovery that isn’t associated with symptoms. This can happen when there are tiny deposits inside the heart muscle. The heart is still by all means okay with it. Always remember to check it during the regularly scheduled visits to make certain that everything is within normal limits.

There could be many reasons for this. Sometimes it's just a case of indigestion or heartburn caused by eating too fast or consuming foods that don't agree with us. Another frequent reason is acid reflux, characterized by a burning feeling in the chest. Stress or anxiety might also be considerations since they can sometimes affect the chest. Eating smaller meals more often and avoiding fatty, spicy foods is advisable. If the matter persists seek medical help to rule out anything serious.
