Cold weather easy to have heart attack


HCMCThe two men, both over 60 years old, were taken to Nguyen Trai Hospital for emergency care one day apart, showing signs of angina in the left chest.

The 65-year-old man from Binh Tan district, last weekend, was going to buy coffee in the morning when he suddenly had an angina in his left chest and fainted. The passerby helped to wake up, he was awake, aware of his surroundings, but the pain in his left chest was like being strangled, spreading from the left chest to the center of the sternum. The pain persisted and increased gradually, difficulty breathing, sweating, and resting did not decrease so family members went to the emergency room. He had high blood pressure for a long time, smoking a lot.

One day later, another man, 64 years old, from District 6, suddenly had a left angina with severe difficulty breathing while sleeping, had to sit up to breathe. He has a history of hypertension, type 2 diabetes, dyslipidemia, and also smokes a lot.

“At the time of admission, both patients suffered from severe chest pain, sweating, very low blood pressure and heart rate, and their lives were threatened,” said Dr. Ho Dung Tien, Head of Cardiology Department 1, Nguyen Trai Hospital, share. Doctors diagnosed both acute myocardial infarction, coronary artery obstruction.

Two patients with cardiac catheterization intervened to set stent to re-open the obstructive coronary artery, helping to eliminate chest pain, pulse, and stable blood pressure. “Both are saved lives by timely coronary intervention”, Dr. Dr. analyzed.

The temperature in Ho Chi Minh City usually drops to 19-21 degrees in the early morning hours, and cold weather is believed to be a risk factor for the elderly to be susceptible to heart attack due to constriction of blood vessels. Research shows that in the cold season, blood pressure usually increases about 5 mmHg higher than that in summer, increasing the risk of cardiovascular complications, stroke.

According to Dr. Dung Tien, patients with coronary artery disease, the need for oxygen for the heart muscle increases in the cold season. At that time, the body increases the number of red blood cells, platelets, blood viscosity, the risk of coronary artery diseases such as chest pain, acute myocardial infarction and stroke.

The doctor recommends that people, especially the elderly, keep warm when the weather turns cold. Limit out when the temperature is too low. People with pre-existing cardiovascular disease should adhere to the current regimen. When there are signs of sudden dizziness, shortness of breath, throbbing pain in the sternum, cold sweat, abnormal heartbeat, need to go to the hospital for prompt diagnosis and treatment.
