Chronic heart failure is caused by reduced myocardial contractility, so lifestyle management is important to achieve a good treatment effect. First, medication: very important, specialist physicians will give you a reasonable treatment plan. Second, life management: is an important guarantee for the treatment of heart failure. Water intake should be limited throughout the life course. Water includes: plain water, fruit, soup, porridge, beverage and infusion amount during treatment. Controlling the amount of intake is the most effective measure. Controlling the amount of intake is equal to reducing the burden on the heart, so that the heart muscle can have a chance to rest, restore the function and relieve the symptoms. It is unreasonable to think that as long as you can urinate, you should drink more. Therefore, limiting the amount of intake is the most fundamental and effective measure to fundamentally relieve the symptoms of heart failure and achieve long-term effects. Third, comprehensive treatment: the drug respects the will, and the amount of living water intake depends on self-consciousness.
