What condition can cause heart failure

summary

When I was a child, I was too naughty and often fought. Later, I was hurt by someone accidentally and suffered a waist fracture. Up to now, I haven't been well, and I can't take vigorous exercise. When I climb stairs, my heart beats abnormally. The doctor says that I have heart failure. Let's talk about what causes heart failure.

What condition can cause heart failure

First, heart failure, also known as "myocardial failure", means that the heart can not pump out the blood supply commensurate with venous return and body tissue metabolism at that time. Often caused by a variety of diseases, myocardial contractility is weakened, so that the blood output of the heart is reduced, not enough to meet the needs of the body, and thus produce a series of symptoms and signs.

Second: due to the high arterial pressure in hypertension, it hinders the heart from pumping blood. When the heart works with high load for a long time, there will be myocardial hypertrophy and increased stiffness, which eventually leads to the obstruction of pulmonary venous blood entering the heart and the formation of pulmonary congestion. Myocardial hypertrophy increases oxygen demand, blood supply is relatively insufficient, often leading to heart failure.

Third, the causes of heart failure include serious arrhythmia, improper medication, infection, etc. Many kinds of infection can lead to heart failure, one of the important factors is respiratory tract infection. Infection can decrease the contractility of the heart, indirectly weaken the function of the heart and even directly damage the myocardium. The most common cause of heart failure in the elderly is respiratory tract infection.

matters needing attention

If heart failure is serious, it will take the lives of patients, so we should better understand the causes of this disease. If infection occurs in daily life, we must treat it in time, and do not overwork at ordinary times.
