Recently, there has been a cooling phenomenon in many parts of China, with a larger magnitude and longer duration of low temperatures compared to before this year. Medical experts remind that severe temperature differences can easily trigger cardiovascular diseases, and both ordinary people and patients with cardiovascular diseases should take corresponding measures to prevent and reduce damage in advance.
"Cooling down can cause some patients' blood pressure to increase. Some hypertensive patients may not have their blood pressure regularly measured, and they may not realize the problem until their blood pressure rises to a very high level." Zhou Yi, chief physician of the Cardiovascular Department at Wuhan Central Hospital, said that rapid cooling will have an impact on patients with different types of cardiovascular diseases. Some patients with coronary heart disease are prone to spasm and contraction of their heart blood vessels during sudden temperature drops, exacerbating myocardial ischemia, or unstable plaques, leading to acute myocardial ischemia; For heart failure patients, if upper respiratory tract infections occur during cooling, it may lead to acute heart failure attacks.
In addition, the director of the Department of Neurology at Wuhan Central Hospital reminded on screen that a large temperature difference between morning and evening can also lead to an increase in patients with cerebral infarction. "Many patients have a stroke after waking up, which is normal when they fall asleep, but they find abnormalities after waking up. Due to uncertain onset time, delayed medical treatment, and other reasons, it is easy to miss the best treatment opportunity." Jing Ping said.
When the temperature drops suddenly, how can ordinary people judge whether the cardiovascular system is affected through physical representation? Zhou Yi reminds that common diagnostic symptoms include chest tightness, palpitations, and shortness of breath. Based on the autonomic nervous system characteristics of the human body, the above characteristics are more common at night, and once the frequency of chest tightness exceeds once a day, it is considered more frequent and requires timely medical treatment at a medical institution.
Experts suggest that in order to avoid the onset of cardiovascular disease, patients can increase the frequency of monitoring blood pressure. In addition to taking medication regularly, patients with coronary heart disease should also pay attention to their blood lipids. Patients with heart failure should try to avoid catching a cold as much as possible.
During cold waves, ordinary people should avoid overwork, lack of sleep, and emotional fluctuations to prevent adverse effects on cardiovascular health. When the temperature drops, outdoor activities should pay attention to cold and warm protection, and indoor temperatures should not be set too high to avoid large temperature differences. At the same time, balancing work and rest, controlling smoking and alcohol, and exercising appropriately are all beneficial to the cardiovascular system.
