Heart failure is a syndrome of cardiac insufficiency caused by various heart diseases, which in the vast majority of cases refers to a decrease in myocardial contractility so that the volume of cardiac output can not meet the body’s metabolic needs, organs, tissues, insufficient blood perfusion, and at the same time, there is a manifestation of the pulmonary circulation and/or the corporal circulation stagnation. Common triggers of heart failure include upper respiratory tract infections, severe arrhythmias, overloading of the heart, and prolonged heavy physical activity. Chronic heart failure patients can be combined with small-dose application of diuretics, you can choose the dosage of the drug according to the degree of edema in patients, mild edema can be oral spironolactone, furosemide, and intravenous furosemide if necessary. However, it must be remembered that diuresis must be tested for changes in blood sodium and potassium at the same time, and if the urine volume is too large, attention must be paid to potassium supplementation at the same time. The current Golden Triangle treatment for heart failure, the three drugs that need to be taken for a long time are spironolactone, prilosec or sartans, and beta-blockers. The medication process should actually assess whether the patient’s heart rate and blood pressure can tolerate these medications. If the symptoms of chronic heart failure are more obvious, especially with rapid atrial fibrillation can be combined with the application of digitalis drugs. Acute heart failure patients with severe symptoms, need to be combined with high-flow oxygen delivery, while the patient is asked to sit in a seated position with both lower limbs hanging down, which can reduce the amount of return blood and reduce symptoms. At the same time intravenous furosemide, the application of vasodilator sodium nitroprusside to reduce the anterior and posterior load of the heart. If obvious sinus tachycardia occurs, can be a small dose of static push deacetyl furanoside. Observe the patient’s situation, if there is still obvious obvious wheezing, difficult to whistle, can be pushed theophylline drugs, such as symptoms of critical necessity can be pushed morphine, can dilate the small arteries, reduce the cardiac afterload, and at the same time can play a role in sedation. Although heart failure can not be cured, but if the patient can follow the doctor’s instructions to take medication, pay more attention to rest, regular review ultrasound, electrocardiogram, chest X-ray, pay attention to the prevention of lung infections, diligently open the windows to enhance their own resistance, but also help to better prevent the progression of heart failure.
