Heart failure patients are cold and hot at the same time due to the lowering of immunity, lowering of cardiac output, and disorders of vegetative mental regulation. 1. Reduced immunity: Because of the weak blood supply ability of the heart in heart failure patients, the immunity of the patient’s body is reduced, the body temperature center regulation ability is weakened, and the patient is easily affected by other diseases, such as colds and flu, which will also easily lead to the phenomenon of hot and cold in patients. 2. Decrease in cardiac output: heart failure patients with decreased ventricular blood supply capacity, decreased cardiac output, poor peripheral circulation to the outside temperature resistance to reduce the ability to make the patient appear cold and hot symptoms. 3. Plant psychiatric disorders: Due to the patients’ long-term adverse psychological condition, it is easy to lead to plant psychiatric disorders, which may cause the patients to feel hot and cold, but the actual body temperature is not high. If the patient has strong symptoms of this kind, you need to go to the hospital in time, and use drugs to relieve.
