“Early Winter Somatosensory” launched online to warn against cardiovascular and cerebrovascular diseases
The cold wind was howling, and the temperature in Shanghai hit a new low yesterday morning, with the lowest temperature in some suburbs being below 4℃. On the road, many pedestrians were already wearing down jackets. According to the forecast of the Shanghai Central Meteorological Observatory, two waves of cold air will hit the country in the near future, and the temperature in the southern region where our city is located will continue to drop. After the impact of this round of cold air, the temperature has rebounded today. There will be a new round of cold air “replenishment” around Thursday, and the city will once again experience cooling, precipitation and strong winds.
“Early Winter Somatosensory” is online. In addition, autumn and winter are the seasons with high incidence of respiratory infectious diseases. The “roller coaster” of high and low temperatures also gives cardiovascular and cerebrovascular diseases an opportunity. The reporter learned from several hospitals in Shanghai that since this round of cooling, the number of visits to cardiovascular medicine, respiratory medicine, neurology and other departments has been on the rise. For people with low immunity, such as the elderly and children, doctors remind them to pay attention to weather changes in the near future, add or remove clothing in a timely manner, keep the room properly ventilated, keep commonly used medicines nearby, and seek medical advice in time if you feel unwell.
Sudden cooling can easily induce acute attacks of chronic diseases
Mr. Zhang has been suffering from “chronic bronchitis” (chronic bronchitis) for many years and has always paid attention to his maintenance. Unfortunately, the recent temperature changes have made him feel a little overwhelmed. He developed symptoms such as cough, sputum, and asthma, so he had to go to the No. 1 hospital in Shanghai. Visit the respiratory department outpatient department of the First People’s Hospital.
“The human respiratory tract is most susceptible to changes in temperature. Recently, there has indeed been a certain increase in the number of patients seeking medical treatment for respiratory diseases.” Xie Guogang, a respiratory and critical care medicine doctor at a city hospital, told reporters that colds, flu, rhinitis, pharyngitis, chronic bronchitis, etc. These are respiratory diseases that are prone to attack in autumn and winter. Many elderly people suffer from chronic obstructive pulmonary disease, bronchial asthma and other chronic diseases. As the temperature drops, they are prone to airway contraction or infection, thus inducing acute attacks of chronic diseases. Severe cases require hospitalization.
“The elderly are frail and the onset of emergencies is more severe. Don’t think of ‘carrying them all’.” Xie Guogang suggested that once the elderly develop symptoms such as fever, sore throat, cough, expectoration, chest tightness and shortness of breath, they should go to the hospital in time to avoid delaying their condition. .
Recently, there have been many patients with colds and coughs. Clinically, some patients clearly have cough symptoms, but no abnormalities were found when they went to the hospital for examination. Why is this? “Many respiratory diseases are seasonal, and coughs are no exception.” Xie Guogang explained that this is often related to dry and cold air irritation, allergic coughs, respiratory infections and other factors. He reminded that patients can start with their diet and daily life, such as eating less seafood, mutton and other fats, keeping warm, keeping the room ventilated, avoiding contact with allergens, etc., and taking protective measures to reduce the onset of the disease.
Myocardial infarction is waiting for an opportunity, so don’t “require demeanor rather than warmth”
In addition to respiratory diseases, autumn and winter are also periods of high incidence of cardiovascular and cerebrovascular diseases, especially patients with chronic underlying diseases such as hypertension, coronary heart disease, and hyperlipidemia. They are also at high risk of cardiovascular and cerebrovascular accidents.
“After cooling down, human blood vessels suddenly shrink, and the most direct ‘sequelae’ is the increase in patients with cardiovascular diseases.” Zhang Qi, director of the Department of Cardiology (North Branch) of Shanghai Oriental Hospital, told reporters that recent outpatient and emergency admission data Look, the number of patients with cardiovascular disease has increased significantly.
Just a few days ago, Zhang Qigang received a patient. Hu, an old man in his 70s, suddenly developed a feeling of chest tightness after morning exercise. After a day of rest, he could not get relief, so he went to the hospital for treatment. The examination showed that Mr. Hu suffered from acute myocardial infarction. After being “bored” at home for a day, he had developed into extensive anterior wall myocardial infarction and his condition was serious. Fortunately, the team performed interventional surgery for him as soon as possible. Currently, Mr. Hu is in stable condition and has gone home to recuperate.
Reviewing Hu’s illness process, Zhang Qi found a key detail. Hu, who suffered from high blood pressure, failed to put on and take off his clothes in time before and after exercise and froze. “Cold can cause vasoconstriction and increase blood pressure. If you catch a cold, cardiovascular accidents are prone to occur. Patients with cardiovascular disease should keep warm at all times and do not ‘have style but not temperature’.”
Looking back at the myocardial infarction cases received in recent months, Zhang Qi said that patients under the age of 50 accounted for nearly 60%, with the youngest in their early thirties. “Even healthy people, including young and middle-aged people, who usually have no discomfort, may suffer from heart disease. They must be more vigilant and ‘protect their family’.” He specifically mentioned that many people are used to adjusting the water temperature when taking a bath in autumn and winter. “Higher water temperature will produce a large amount of water vapor, resulting in insufficient oxygen content in the air. People with heart problems will suffer from insufficient oxygen supply, thus causing cardiovascular accidents. Therefore, don’t take a bath for too long, 10 It’s better to wait until 20 minutes.”
Doctors also reminded that in addition to keeping warm, patients with chronic diseases should have commonly used medicines at hand and avoid stopping medicines without authorization. Randomly stopping or delaying medication can cause a sudden rise in blood pressure, which may be life-threatening. Patients with chronic diseases can also prepare their own blood pressure monitor at home to monitor their blood pressure at any time.
