Cardiac shadow enlargement is not a single disease, but an imaging change. There are usually three main reasons for the increase of cardiac shadow:

First, the heart itself appears hypertrophy, such as hypertensive heart disease, coronary heart disease, heart failure and so on. This can increase the shadow in my heart;

Secondly, pericardial effusion can show imaging changes similar to cardiac hypertrophy on conventional chest radiographs, and the heart shadow is also enlarged;

Third, the heart shadow caused by external factors has increased significantly. The size of the heart is evaluated by the cardiothoracic ratio on the chest radiograph. Most normal people have a cardiothoracic ratio of less than 0.5 at the end of inspiration.

If the heart shadow increases, it is basically caused by hypertension or valvular disease on the heart. We need to find the corresponding reasons. First, there will be pain between the right ribs. Generally, this feeling of pain will gradually worsen after half a month of onset, so the condition is getting worse and needs timely treatment. If the heart shadow increases too much, the heart disease load will increase, leading to heart disease. Besides mild treatment in diet, you should also pay attention to your mood.
