With the aging of our society and the prevalence of hypertension and coronary heart disease, the prevalence of heart failure has been rising. There has also been a gradual increase in the number of patients who survive sudden cardiac arrest. The danger of heart failure is that its symptoms develop slowly, and many people simply do not understand and pay attention to the early warning signs. Middle-aged and elderly people are prone to heart failure experts pointed out that any heart disease to the late stage of heart failure, such as coronary heart disease, hypertension, diabetic cardiomyopathy, myocardial infarction, etc. In addition, some of the primary cardiomyopathy can also cause heart failure, such as dilated cardiomyopathy, hypertrophic cardiomyopathy, and so on. Among the causes of heart failure, the former type of disease is common, and the prevalence of this type of disease is common in middle-aged and elderly people, especially the elderly. Be alert to fatigue, tension can also induce heart failure, excessive physical labor and emotional excitement, can also induce heart failure. Elderly people should exercise restraint when watching TV and control the time they spend with their loved ones in order to avoid fatigue-induced heart failure. Early signs of heart failure in the elderly 1, labor or stairs, dyspnea; 2, sleep suddenly dyspnea, sit up and get better, sleep at night must be cushioned head; 3, swelling of the lower limbs, decreased urination; 4, did not suffer from the cold but cough, phlegm, mostly foamy sputum, or with a little blood, panic, breathlessness; 5, lethargy, insomnia, fatigue, irritability, appetite; 6, aggravation, twitching of limbs, apnea, and a few days of sleep. Twitching of the limbs, apnea, cyanosis, but after the attack, immediately return to normal; 7, blood pressure drop, heart rate accelerated, pale, cold and clammy skin, irritability; 8, extreme difficulty in breathing, with a sense of suffocation, coughing, and cackling a large amount of pink foamy sputum. For the above symptoms, if 1-5 items can be matched, for the typical performance of early heart failure, should pay attention to; some patients a little shortness of breath to suspect that their heart failure. In fact, many patients’ shortness of breath is not caused by heart failure, but has other reasons. The detailed identification of these two to be patients to do may not be easy, need to do some objective examination to understand. Early heart failure mainly has some of the following symptoms: tiredness, insomnia and irritability; increased nocturia at night during sleep; painless heart attack and so on. At the same time, since these symptoms are easily confused with other diseases, it is important to be vigilant when these situations occur. Therefore, it is best to go to the hospital, combined with their own symptoms that have appeared, in order to clarify whether there is heart failure. There are eight common causes of heart failure in the elderly: 1, infectious diseases, especially respiratory infections, accounted for the first cause, 97% of the elderly suffering from pneumonia died of heart failure. 2, arrhythmia, especially respiratory infections, accounted for the first cause, 97% of the elderly suffering from pneumonia died of heart failure. 2, arrhythmia, especially tachyarrhythmia, such as supraventricular tachycardia, atrial fibrillation, atrial park, etc. can increase the ventricular rate, reduce the ventricular filling time, increase myocardial oxygen consumption, etc., tachyarrhythmia is one of the important triggers of heart failure. 3, blood transfusion, fluid transfusion or excessive salt intake. 4.Overexertion of physical strength, excessive mental stress and emotional excitement. 5, Rapid changes in the environment and climate. 6, Improper treatment, such as digitalis drugs underdose, poisoning or overdose, excessive diuresis. 7.Severe anemia, hyperthyroidism, pulmonary embolism and so on. 8.Inhibition of myocardial contractility of drug effects such as β-blockers, quinidine, isobarbital, bis-isopropylpyrimethamine, and so on. It should be emphasized that prevention and control of the above causes and triggers is an important part of the prevention and treatment of heart failure in the elderly.
