DiseasesHeart, blood and lymph nodes

Pain in the chest

If you get chest pain it can have many different causes. One of the most common is that the muscles in the chest hurt because you strained them more than usual. Mental stress can also create a feeling of pain or discomfort in the chest. Occasionally, chest pain may be due to diseases of the heart, stomach or muscles. A strong, pressing pain in the chest can be symptoms of angina or heart attack and then it is important to seek care.

Lymphedema is a swelling of the body. The swelling is because the fluid in the body called the lymph is difficult to transport and instead accumulates in one place. The treatment is to reduce the swelling and to prevent the size of the lymph nodes.

Swollen lymph nodes

It is common for children and adults to have swollen lymph nodes. Then they are often tender and bigger than they usually are. For example, it may be due to a viral infection in a cold, a bacterial infection in the throat, or a wound that is infected. If you have swollen lymph glands larger than two centimeters, they should be examined by a doctor.

DiseasesHeart, blood and lymph nodesInflammation and infection of the heart


If you have a myocardial infarction, the double membrane that is around the heart has become inflamed. In rare cases, fluid may accumulate between the membranes. Then the heart becomes more difficult to pump the blood and the blood circulation becomes worse. With treatment, inflammation can go away quickly, but sometimes it takes months or years.

DiseasesHeart, blood and lymph nodesHeartbeat


Heart palpitations in the form of extra beats, hard heartbeats or short-term heart murmurs are common and occur at all ages. Usually, there is nothing to worry about, especially if the trouble comes in connection with stress or worry. But if you get heartache and at the same time feel sick, get chest pain or difficulty breathing, you should seek treatment immediately.

Permanent atrial fibrillation

Atrial fibrillation means that the heart beats irregularly and often even faster. This means that the heart cannot pump around the blood in the body as efficiently as it usually does. Permanent atrial fibrillation is the most common cause of stroke. This is because the flicker degrades blood circulation in the atrium of the heart, making blood clots more easily formed.

Heart Valve Diseases

In the heart are four flaps that act as valves and prevent the blood from being pumped in the wrong direction. The flaps can become too tight or start leaking, which can lead to different types of heart valve diseases. They are often detected when the doctor listens to the heart and hears wheezing. If the failure of the valve causes symptoms or affects the functioning of the heart, surgery may be required to replace the heart valve that does not work with a new one.

Heart failure

In the event of a heart failure, the heart cannot pump enough blood into the body. This may be because the ability of the heart muscle to contract is weakened. The impaired pump function may also be due to the fact that the heart muscle cannot relax properly. Heart failure occurs at all ages, but is most common in the elderly.

Different types of heart malformations in children

Congenital heart defects due to birth defects are the most common heart disease in children. It may be, for example, holes in the partitions of the heart or constrictions of the flaps in the heart or large vessels. About one-third of the congenital injuries are treated during the first months of life. Most children are treated with good results, but often the child needs to be followed up for a long time.

Hypertrophic Cardiomyopathy, HCM

Hypertrophic cardiomyopathy, HCM, is a disease that thickens the heart muscle. Some people do not notice the disease while others get short of breath, get chest pain, palpitations and fainting. Thickening of the heart muscle is most often found in the teens, but many people are diagnosed with HCM only at adulthood. Everyone can get the disease, but the risk is greater if you have a close relative with the diagnosis of HCM.
