Reporter Chen Yi / Taipei Report
The coldest winter current is violent, all of Taiwan is icy, and many mountainous areas are snowing. It is reported that almost 30 people have died suddenly last night so far. It remains to be clarified whether the cause of death is directly related to temperature, but the cold winter is a sudden death from cardiovascular disease. The good season.Supervisor Zhang Zhao, Cardiovascular Center, Cathay General HospitalIt is recalled that, in addition to myocardial infarction, angina pectoris and heart failure, with which most people are familiar, strokes can also cause surprise attacks, especially when people “get up” and “stand up.” bathes “, death may be hidden in the” temperature difference “.

The Central Meteorological Office continues to issue special low temperature reports. It is estimated that from this (8) night until tomorrow morning it will be the coldest moment of this wave of cold currents, and the temperature in some flat areas may be below 6 degrees. According to statistics from county and city fire departments, there were nearly 30 suspicious deaths in cold weather yesterday, including “youth” in their 30s and 40s.
The doctor emphasized that “temperature difference” is the killer of blood vessels. When the temperature changes dramatically, human blood vessels repeatedly “dilate and contract.” Vasoconstriction increases peripheral resistance. If there is also the problem of coronary artery stenosis, the heart cannot get enough oxygen. , It will cause angina. Once the blood vessels contract sharply, they can also rupture the fatty plaques in the walls of the originally narrow coronary arteries, resulting in hyperacute thrombotic reactions and vascular obstruction, leading to acute myocardial infarction and myocardial necrosis. , which can be life threatening.
Dr. Zhang Zhaojian recalled that cold weather can easily cause vasoconstriction and blood pressure. In addition to directly threatening the heart, the low temperature can also increase the possibility of a stroke.Clinical experience shows that sudden death often occurs in the early morning hours of winter, especiallyGet upAt that time, because the sympathetic nerves are excited right after a person wakes up, the sympathetic nerves promote vasoconstriction when excited, and the difference in temperature between the bed and the environment leads to increased vasoconstriction. Zhang Zhaojian suggested not jumping out of bed at once in winter and “sitting down” for at least 30 seconds, and then slowly getting out of bed after the body gradually adapts to the temperature difference.
Many people will go up the mountain to soak up the cold weather.spa, Zhang Zhaojian reminded patients with high blood sugar, high blood pressure and high blood lipids and cardiovascular disease to avoid “whole body immersion.” It is advisable to switch to the half body dive to avoid vasodilation of the extremities and a sudden increase in peripheral blood flow, which can cause cardiovascular or brain problems Vascular emergencies.
Also, it is not advisable to soak in hot springs for a long time in cold weather, and drink enough water before and after bathing to avoid dizziness caused by lack of water in the body; the water temperature should not exceed 40 degrees, do not dip into cold water at once, dip into hot water at once, because the temperature difference between hot and cold is large. It will cause rapid expansion of blood vessels, sudden contraction of the cardiovascular system, or obstruction of blood flow, which can easily cause a myocardial infarction or ischemic stroke.

Zhang Zhaojian revealed that although the majority of sudden death cases in cold climates are in the elderly, sudden death has also been encountered in the young, cases that usually lack telltale symptoms and make people sick. catch you off guard. Therefore, in addition to staying warm in winter, if people suddenly feel chest tightness, chest pain, dizziness, shortness of breath, cold sweats, etc., they should immediately seek medical attention.
