This is because an environment in which blood clots in blood vessels can be created in hot weather. Usually, exposure to high-temperature and humid environments causes a lot of sweat and water in the body decreases. At this time, the viscosity of the blood can be increased, creating an environment in which blood clots can occur with blood that has become sticky.
In addition, the contraction and relaxation of blood vessels are active to maintain the homeostasis of body temperature, and it may strain blood vessels.
In a study by the American Heart Association, it is reported that the number of patients with myocardial infarction increases by 20% when the temperature rises above 32 degrees Celsius. In fact, the number of patients treated for myocardial infarction in Korea over the past five years was 483,000 in summer (June-August), and 471,000 in winter (December-February). In addition, the number of patients treated for heart failure for five years was higher in summer (592,060) than in winter (574,779).
Professor Oh Seung-wook of the Department of Cardiology at Catholic Kwandong University's International St. Mary's Hospital said, `In general, it is right to be careful about heart disease in times of extreme daily temperatures, but you should also be careful during hot weather.' `If there are risk factors for cardiovascular disease such as blood pressure or hyperlipidemia, refrain from outside activities in hot and humid weather and drink enough water to avoid dehydration.'
There are various risk factors for cardiovascular disease, but representatively, there are ▲age of old age ▲ obesity ▲ drinking and smoking ▲ chronic diseases (hypertension, hyperlipidemia, diabetes, etc.) ▲ family history.
The rules for keeping your heart healthy from the heat are simple. When a heat wave warning or warning is in effect, people with chronic diseases, the elderly, and cardiovascular risk factors should refrain from external activities as much as possible. If you are active outdoors, you should drink enough water and rest to prevent dehydration. It is better to drink bottled water than caffeine drinks.
In addition, it is recommended to wear well-ventilated clothes to minimize heat absorption, and it is necessary to be with others when exercising or doing outdoor activities.
Professor Oh Seung-wook emphasized that `Cardiovascular disease is an ultra-emergency disease that competes for minutes with cerebrovascular disease.' `If symptoms such as unbearable chest pain, difficulty breathing, dizziness, and cold sweat occur, you should report it to 119 or visit a hospital for treatment.'
