Hanoi (VNS/VNA) - The cold weather which has hit the northern regionwith temperatures of 8 to 10 Celsius degree has reportedly been accompanied bya surge in the number of people suffering from strokes.

Dao Viet Phuong, from Bach Mai Hospital’s Stroke Centre, said the centre has received 2,000 strokepatients since it was established in November.

More people have recently also been taken to the National GeriatricHospital (NGH) and the 108 Military Hospital.

Nguyen Danh Cuong, deputy head of the Emergency and Stroke Department ofthe NGH, said the cold snap was the reason for an escalation in the number ofsenior citizens hospitalised for emergency treatment.

The hospital admitted 50-60 patients a day compared to 30-40 on normaldays. Most of them are serious cases with blood pressure problems, heartdiseases and strokes; some even need a ventilator, he said.

"As the organs of the elderly are ageing, they are more susceptible torespiratory diseases such as sore throats or bronchitis than young people. Asudden change in temperatures can lead to a higher risk of a stroke,” hetold Suc khoe va doi song (Health andLife) newspaper.

Hospital admission rates for strokes have also reportedly increased inmedical centres in northern provinces like Hoa Binh, Quang Ninh and Lao Cai.

Ta Huy Kien from Hoa Binh General Hospital said each day the hospitalreceived 7-8 stroke patients during cold snaps.

The number of patients seeking treatment for the disease hit nearly 240 fromDecember 1 last year to January 10, he said, adding that strokes often occurredin people aged from 50 years old with underlying health conditions includingdiabetes and high blood pressure.

According to Phuong, the cold weather is a factor that heightens the risk ofstrokes.

When temperatures go down blood vessels in the skin constrict so the bodydoesn't waste a lot of heat, which can raise blood pressure. Many patients arehospitalised with a paroxysmal 130/80 mm Hg blood pressure.

High blood pressure is the cause of 80 percent of strokes in Vietnam.

Scientists have discovered a reduction of every two mmHg in blood pressureresults in a 10 percent reduction in deaths from stroke.

If the blood pressure is maintained at the optimal level of 120/80 mmHg, itwill prevent stroke complications in most cases.

Long-term hypertension will increase atherosclerosis and formation of bloodclots which easily causing cerebral infarction. In addition, high bloodpressure also increases the pressure on brain arteries, causing blood vesselsto rupture, causing brain bleeding, Phuong said.

Cold weather also makes many people tend to eat more salty and more fatty foodswhile reducing exercise.

“It is dangerous that when it is cold, patients with hypertension are too lazyto take medicine or run out of medicine but they are afraid to go to seethe doctor again, making the blood pressure uncontrollable,” he said.

It is estimated an annual incidence of strokes in Vietnam at 200,000 and thefigure increases by about 2 percent every year. However, people don’t haveknowledge about the disease, measures to prevent it or first aid, said Phuong.

He said one of the most important criteria for reducing complications instroke patients was to go to the hospital early.

“As soon as one of your relatives has such symptoms as hemiplegia,distorted mouth or slurred speech, you should immediately call an ambulance andbring them to the nearest hospital.”

“We always want patients to arrive at the hospital within three hours from thetime their symptoms appear but it is extremely difficult. There are only a fewcases in Hanoi when this happens while the rest are mostly late.

"Many people are hospitalised after 2-3 days. At that time, treatment isvery difficult and the ability to recover is limited," he said.

For patients with cerebral haemorrhage, if they come to the hospital early,their blood pressure will be controlled, greatly reducing after-stroke risks,according to Phuong.

The Ministry of Health has sent an urgent dispatch to departments of health incities and provinces in the northern and central regions ordering preventivemeasures to protect people’s health in response to the cold snaps.

They were asked to guide people on how to keep warm outside and in closedrooms.

Health facilities were also required to ensure there was enough medicine fortreatment and enhance control over diseases including blood pressure,cardiovascular and respiratory diseases, especially in the elderly andchildren.

The National Centre for Hydro-Meteorological Forecasting said that temperaturesin the north will continue dropping in the next few days. 

Cold air hit the northern delta area on January 19 with the lowest temperatureof 9-12 degrees Celsius and 5-8 degrees Celsius in mountainous areas. 

Meteorological experts have warned that snowfall is predicted to occur in thehigh mountain areas of Lao Cai and Lai Chau provinces in the next few days./.
