Why heart failure?

summary

The heart is the only source of blood supply to the human body. We all know that if a person's heart has a problem, it means that the machine has no power supply. Let's popularize the basic causes of heart failure.

Why heart failure?

First: myocardial contractility weakened: myocarditis, cardiomyopathy and coronary heart disease. Increased afterload (pressure load): hypertension, aortic stenosis (left ventricle), pulmonary hypertension and pulmonary stenosis (right ventricle). Increased preload (volume load): mitral stenosis, tricuspid stenosis, mitral regurgitation, aortic regurgitation, atrial septal defect, ventricular septal defect and diseases with increased metabolic demand (hyperthyroidism, arteriovenous fistula, etc.)

Second: infection: respiratory tract infection is the most common and important inducement, especially for the elderly. Infective endocarditis as a cause of heart failure is not uncommon, medical education network collection often due to the incidence of secret and missed diagnosis. Improper treatment: mainly due to improper use of digitalis (excessive or insufficient), and combined use of inhibition of myocardial contractility (verapamil β Blockers * or drugs that cause water and sodium retention (large doses of non steroidal anti-inflammatory drugs).

Third: arrhythmia: especially atrial fibrillation and other rapid arrhythmias with fast ventricular rate. Pulmonary embolism. Excessive physical or mental burden. Patients with increased metabolic needs, such as hyperthyroidism, arteriovenous fistula and so on. Infection, arrhythmia and improper treatment are the main causes of heart failure.

matters needing attention

For patients with heart failure, in daily life, we must pay attention to the protection of the heart. If there is a problem with the heart, we must go to the hospital for treatment. Do not treat blindly, so as to avoid future trouble.
