Yoga for pregnant women reduces labor pains

The reporter learned from Shenzhen Sun Yat-sen Cardiovascular Hospital on the 13th yesterday that due to continuous low temperatures around the Spring Festival, the number of patients with cardiovascular and cerebrovascular diseases increased by 40% compared with the same period last year, including more critical and emergency patients. Considering that the temperature will remain low in the next few days, doctors remind citizens that if people with cardiovascular disease feel unwell due to weather conditions, they should promptly adjust the dose of medication according to doctor's advice. Special attention should be paid to preventing colds to avoid more serious diseases caused by colds.

The hospital admitted a patient with heart failure caused by a cold on the first day of the New Year. When he first arrived at the hospital, he was asthma and had difficulty breathing. He is still receiving treatment in the cardiology intensive care unit. According to Wang Lili, deputy chief physician of the intensive care unit of the Department of Cardiology, the patient is a woman in her 60s who has had heart valve replacement surgery before. I got a cold due to the cold weather one week before the Spring Festival, and I had heart disease before. Upper respiratory infection became a cause of heart failure. "When the patient was first sent to the hospital, his condition was very dangerous. We immediately treated the patient with anti-infection and heart function maintenance, and now his condition has stabilized." Wang Lili said.

Data from the hospital's outpatient department shows that compared with previous years, the hospital admitted 40% more cardiovascular and cerebrovascular patients this year. Peng Xiaoling, director of the emergency department, said: "As the Spring Festival approaches, there was a time when beds were tense." According to Peng Xiaoling, due to the low temperature in winter, the blood vessels in the body contract, and the rise in vascular resistance and blood pressure increase the burden on the heart. This can directly affect the blood supply to the heart and induce angina pectoris or myocardial infarction. Contraction of cerebral blood vessels causes insufficient blood supply to the brain, which increases the risk of stroke. "There have been a lot of serious and emergency patients admitted recently."

What should people with high blood pressure pay attention to in the near future? Peng Xiaoling said that patients with hypertension should pay attention to observing changes in blood pressure and adjust the amount of antihypertensive drugs in a timely manner. In winter, the antihypertensive drug for patients with hypertension should be increased. For example, the original daily dose was 2.5 mg, but in winter, the drug may be increased to 5 mg. A single antihypertensive drug may have to be adjusted to the combination of multiple drugs in winter, and the intensity of medication will be increased. However, how to adjust the dose should be adjusted according to the doctor's advice. At the same time, we should pay attention to preventing colds so as not to aggravate cardiovascular disease.

As for how to prevent cardiovascular disease, Peng Xiaoling pointed out that citizens should add clothes in time, drink more water, and eat more light food that is easy to digest. In addition, you should pay attention to the intensity of morning exercises and do not carry out heavy exercise activities on an empty stomach. Eat more foods rich in fiber to keep bowel movements smooth. Don't eat and drink too much during dinner during the festival and maintain a happy and stable mood. Editor in charge: Hu Yifeng
