Recently, the “new coronavirus” pneumonia has become a matter of great concern to everyone. Almost all media outlets have devoted most of their space to this outbreak, and articles about the “new coronavirus” have been pouring in, both from the public media and the self-published media. Most of the articles are about the notification of this epidemic, and how to prevent infection and reduce the spread. This has played a very good positive role in guiding the public. However, we should not forget that our country is a very populous country, and we also have the largest number of people with cardiovascular diseases. We should also pay attention to patients with cardiovascular diseases who are under the shadow of the epidemic. What do patients with cardiovascular diseases need to pay attention to? First of all, among the announced deaths due to the novel coronavirus, we find that these seriously ill patients are often comorbid with underlying diseases, mostly diabetes or other cardiovascular diseases. That means patients with cardiovascular diseases face a higher risk of becoming seriously ill or even dying once they have contracted this virus. Therefore, patients with cardiovascular disease should pay more attention to protection, reduce going out, wear masks, wash hands frequently, and avoid contact with patients with fever and sore throat as much as possible. Even if it is not a “new crown” infection, the common flu can have serious consequences if it occurs in a cardiac patient. This is especially true for patients who have had a myocardial infarction in the past and now have poor heart function and heart failure. Because of their poor cardiac function, it will cause stagnation of the pulmonary circulation, they have a lower immunity than others, once infected with the virus, it will soon develop into a serious intrapulmonary infection. So family members of cardiovascular patients must instruct those around them to strengthen protection. (About how to wear masks, what masks are appropriate, how to wash hands, etc. has been more popular science articles, this article will not repeat) Because of the recent hospitals are the most likely to occur in the possibility of cross-infection, most of the hospitals are now in a state of emergency, and some hospitals general outpatient clinics are not even open. Therefore, if cardiovascular patients do not have obvious symptoms of chest pain, or the aggravation of previous symptoms, it is generally not recommended that you visit the hospital frequently. Some patients had been coming to the hospital regularly every week for prescriptions, we now strongly recommend that you try to prepare a 2-month supply of medication at one time. If there is no change in your condition, you can simply continue to take your medication as prescribed by your hospital doctor. This will avoid going to the hospital or pharmacy, which increases the risk of cross infection. Always look at the date of manufacture when buying medicines to avoid buying medicines that are out of date and cause adverse reactions. In addition, medicines should be stored in a room temperature, cool and ventilated place as far as possible, and in the case of nitroglycerin, it must be kept away from light and in a black box. Insulin, which is used by some diabetic patients, should be stored in a room temperature or low temperature refrigerator according to the instructions. Patients with cardiovascular disease should pay more attention than usual to all their vital signs. It is recommended that you take your temperature at least twice a day, in the morning and in the evening, or anytime if you have symptoms such as peripheral discomfort or chills. Blood pressure should be measured at least four times a day, in the morning, at noon, in the afternoon and evening, and before going to bed, and heart rate should be measured at the same time. If you have abnormal blood sugar you also need to measure your fasting and at least one postprandial blood sugar every day. If abnormalities in blood pressure or blood glucose are detected, then medications should be adjusted as early as possible to avoid having to go to the hospital because of poor blood pressure or blood glucose control, which can lead to other serious problems. For patients with heart failure, it is important to keep a detailed daily record of fluid intake and output, that is, the total amount of fluid intake from diet plus water, and the amount of fluid eliminated by urination every day, in order to maintain a balance of fluid volume. Large fluid intake for a short period of time may trigger an exacerbation of acute heart failure. So when do you need to go to the hospital urgently for treatment? If you have the following symptoms: 1. Persistent high fever (higher than 38.5 ℃) for more than two days, accompanied by severe cough, coughing up pus sputum, bloody sputum or chest pain with rapid respiratory rate, dyspnea, cyanosis of lips and mouth. 2. Mental changes: unresponsiveness, lethargy, agitation, convulsions, etc. 3. Severe vomiting, diarrhea, dehydration manifestations. 4. Combined pneumonia. The above symptoms often suggest that you have a combination of influenza or other viral infections that require immediate emergency hospitalization. In addition to the aggravation of the original disease, such as coronary heart disease patients with severe chest pain, persistent unrelieved. Patients with heart failure have severe dyspnea, wheezing, can’t lie down, and even cough up pink foamy sputum. Patients with lung disease suffer from severe coughing, coughing up sputum and wheezing. Patients with diabetes have fuzzy consciousness, and their breath smells like rotten apples, all of which suggest an aggravation of your pre-existing illness and require the first visit to the hospital. However, it is important to note that patients with fever must first go through the “fever clinic” screening before they can be further treated in other related clinics. The epidemic is an emergency, and the whole country is united in its determination. We believe that under the leadership of the Party, with the effective cooperation of all departments, the dedication of all medical personnel and the unity of all people, we will definitely overcome this epidemic.
