In particular, elderly patients with heart disease should pay more attention to their daily life to avoid a fever and a cold from developing into a heart attack. So, what is the connection between fever and cold and heart disease? There is a high risk of lung infection caused by fever and cold. The lungs are responsible for the oxygen exchange between the body and the outside world. Blood enters the pulmonary artery from the right ventricle. After exchanging oxygen and carbon dioxide according to pulmonary capillaries, pulmonary veins return to the left atrium and are sent to the body according to ventricles.
Pulmonary infection can obviously reduce the high efficiency of gas exchange in pulmonary capillaries, which may lead to the decrease of oxygen in blood. At this time, in order to ensure the difference between the normal oxygen demand of the body and the insufficient oxygen supply in the blood, the heart must accelerate its heartbeat to deliver a large amount of blood to the whole body, thus increasing the workload of the heart. Heart. For patients with heart disease, the increase of cardiac workload makes the already difficult heart unable to bear the load, and even causes heart failure, which further aggravates the condition.
Influenza is more risky than viral influenza and poses a greater threat to heart patients. Viral cold is relatively easy to treat, and influenza is very easy to feel and irreversible. At present, it has a longer medical history and is more harmful to heart function. Heart disease caused by long-term fever and cold will be the cause of heart failure and will accelerate the heart attack or vascular infarction caused by myocardial infarction. Therefore, the elderly should pay more attention to fever and cold, and pay attention to going to the hospital immediately. Besides taking medicine on time, they should also pay attention to bed rest.
