Beware of heart failure caused by cold in winter

Clinical statistics show that winter is a high incidence period of various “heart events”, including myocardial infarction, acute heart failure, sudden cardiac death and so on. Experts said that cold, cold and fatigue are the three major killers threatening heart health in winter.

According to the experts, in the clinical outpatient department, it was found that many heart disease patients insisted on going out early to exercise or washing their faces with cold water in order to enhance their resistance, hoping to achieve certain results. However, things went against our wishes and brought hidden dangers to our health.

Because cold stimulation can excite people’s sympathetic nerves, increase myocardial oxygen consumption, lead to vasoconstriction, increase blood pressure and coronary artery spasm, increase the burden of the heart, and lead to angina pectoris, myocardial infarction, and even arrhythmia, heart rupture, heart failure, cardiac arrest, sudden death and other complications.

expert reminder:

Patients with coronary heart disease should pay attention to weather changes at any time and add clothes in time. It should also be noted that the water temperature should be moderate when taking a bath, and the action should be as light as possible to reduce the stimulation of cold and hot water to the heart. Patients should avoid some outdoor physical activities in the morning. The exercise time should be from 9:00 to 10:00 after the sun comes out, avoiding the time period from the early morning to the morning when the incidence rate is highest.

In addition, avoid washing your face with cold water to avoid sudden stimulation of cold water inducing angina. When washing clothes and vegetables, do not immerse your hands in cold water for a long time, but use warm water. Also, patients with heart disease should not frequently take a bath in a bathroom with poor air circulation in winter.

cold – induce heart failure

The 70 year old Liu Lao Han caught a cold a few days ago. He took medicine at home for a week and failed to control it. Instead, he developed a fever and cough. The old man planned to go to the hospital the next day. Unexpectedly, his condition suddenly worsened in the middle of the night and he was out of breath. His family rushed to the hospital for rescue. The emergency doctor diagnosed acute heart failure, which was caused by a long cold and respiratory infection.

In cold weather, it is easy to catch a cold and suffer from lung infection. Lung infection will increase the burden of the heart. In addition, every 1 ℃ rise in body temperature during fever will increase the heartbeat by about 16 times. The heartbeat will accelerate, which increases the oxygen consumption of the myocardium and increases the nutrients required by the heart itself, but the function of the heart can not provide them. The result of this vicious cycle is the occurrence of heart failure.

expert reminder:

It is easy to catch a cold in winter, especially after the elderly catch a cold, they must not take it lightly. In addition to taking medicine in time, they should also pay attention to bed rest and do not exercise, so as not to increase the heart load. It should be noted in particular that the early symptoms of heart failure are only wheezing, which is easy to be confused with asthma. Therefore, when wheezing symptoms occur, you must go to the hospital for examination to find out whether it is cardiogenic or bronchial. In addition, when infusing after a cold, the dripping speed must not be too fast, so as not to increase the burden on the heart. Clinically, it is very common to rescue patients with acute heart failure caused by too fast infusion.

There are relatively many holidays in winter. Clinically, it is found that every holiday, the number of patients with heart disease recurrence will also increase significantly. Many patients are over excited and excited during family reunion, which leads to increased blood pressure, heart rate and myocardial oxygen consumption. It is easy to induce arrhythmia, angina pectoris, myocardial infarction and even sudden death. Special attention should be paid to the fact that people who usually have no history of heart disease may also have a heart attack due to excitement, and some people may suddenly faint.
