Lobular hemorrhage under the finger and toenail is one of the signs of infective endocarditis. Infective endocarditis (IE) is an inflammation of the inner lining of the heart valves or ventricular walls caused by direct infection with microorganisms. So, what is good for patients with subungual lobe bleeding in finger and toe nails? The following is a brief introduction: 1. slow into drinks. When drinking a lot of water, tea, soup, fruit juice, soda or other beverages at one time, it will rapidly increase the blood volume, which in turn increases the burden on the heart. Therefore, do not drink too much, preferably no more than 500 ml at a time. When you need to drink more water, divide it into several drinks, a little less each time, and a longer interval. 2, should supply sufficient vitamins and the right amount of inorganic. Such as vitamin B1 and vitamin C, to protect the heart muscle. Supply the right amount of calcium to maintain normal heart muscle activity. Potassium has a protective effect on the heart, and causes arrhythmia when insufficient. When using diuretics, in addition to potassium, should also pay attention to the supply of magnesium and zinc. 3.Appropriately limit the intake of protein and caloric energy. In heart failure, daily protein can be controlled at 25-30 grams and 600 kcal of heat energy; after 2-3 days, protein can be increased to 40-50 grams and 1000-1500 kcal of heat energy. After the condition improves, protein and caloric energy should be increased gradually, but not too high, so as not to increase the load on the heart.
