The Department of Disease Control warns "Cardiovascular disease" is the leading silent killer caused by multiple combined factors. It advises the public to closely observe warning signs and adjust their lifestyle to prevent the disease.
On 24 August 2026, Dr. Montien Kanasawat, Director-General of the Department of Disease Control, stated that cardiovascular disease (CVD) is the number one cause of life-threatening conditions. This group of diseases directly affects the heart or the blood vessel system, including both veins and arteries.
It results from multiple factors, including high blood pressure, unhealthy diet, diabetes, obesity, kidney disease, high blood lipids, air pollution, smoking, lack of exercise, harmful alcohol consumption, stress, as well as family history and aging.
Dr. Niti Hetanurak, Deputy Director-General of the Department of Disease Control, said the public should carefully watch for emergency warning signs such as chest pain, tightness in the center of the chest, pain radiating to the left shoulder, arm, or jaw, accompanied by palpitations, sweating, dizziness, or fainting. They should promptly seek medical help. If a patient loses consciousness and stops breathing, immediately perform chest compressions until medical personnel arrive and call 1669 for urgent assistance. If an automated external defibrillator (AED) is available nearby, attach it and follow the device's instructions.
Dr. Woraya Luang-on, Director of the Non-Communicable Diseases Division, added that although cardiovascular disease is dangerous, everyone can prevent and reduce risks by changing daily habits. Start by exercising at least 30 minutes daily or accumulating 150 minutes weekly, quitting smoking including e-cigarettes, abstaining from alcohol and all drugs, and having an annual health checkup at least once a year.
Regarding diet, people should choose healthy foods and avoid those that are excessively sweet, fatty, or salty, while also maintaining mental well-being by managing stress and keeping body weight within a normal range, maintaining a body mass index (BMI) between 18.5 and 22.9 kg/m².
Additionally, it is important to get 7 to 9 hours of sleep per day and avoid staying outdoors or exercising outside on days with high air pollution for heart safety. Patients with a history of heart disease should receive medical guidance to adjust their exercise appropriately. For more information, contact the Department of Disease Control hotline at 1422.
