1, outstanding mental symptoms: the heart is the most important organ in our body, and heart failure is a heart problem. Heart failure is often accompanied by insomnia, anxiety, or lethargy, apathy, sluggishness and so on. This is related to the decrease of cardiac output and hypoxia of brain cells during heart failure.

2. Symptoms of heart failure are easy to be covered up: many diseases often coexist and influence each other in the elderly, complicating the condition and covering up the symptoms of heart failure. Pay attention to the heart rate and breathing of the elderly. If there is rapid heart rate or arrhythmia, paroxysmal dyspnea, you should consider heart failure and see a doctor in time.

3. Increased nocturia: Increased nocturia is due to increased daytime activity, relatively insufficient cardiac blood volume, decreased cardiac output, and decreased renal blood perfusion, so urine volume is reduced; However, when the elderly stay in bed at night, the blood volume and cardiac output increase relatively, which leads to an increase in nocturia and becomes one of the signs of cardiac insufficiency.

4, gastrointestinal symptoms: heart failure is often accompanied by visceral blood stasis, so that patients have different degrees of gastrointestinal symptoms, usually manifested as loss of appetite, nausea, vomiting, bloating and so on.
