World Heart Day 2026: Theme, History, Risk Factors and Prevention

World Heart Day is marked every year on 29 September for raising awareness concerning CVDs, their risk factors and preventive measures against them. For 2026, the theme will be “Don’t Miss a Beat”, emphasizing the significance of spotting warning signs and being mindful about heart health. The campaign stresses the need for people to concentrate on preventing CVD, detecting it in its early stages and leading a healthy life. The WHO has continuously identified tobacco usage, poor diets, physical inactivity, hypertension and other risk factors as significant contributors to cardiovascular diseases.

History of World Heart Day

World Heart Day has evolved into a global campaign aimed at increasing awareness about cardiovascular diseases and is coordinated by the WHF with WHO’s assistance. It is marked annually on 29 September and has now become an international forum for promoting awareness about CVDs.

Through various campaigns on World Heart Day, WHO has highlighted many issues like physical inactivity, tobacco usage, unhealthy diets, excessive salt intake and cardiovascular health among diverse populations.

Observing World Heart Day also helps to complement other public health initiatives to reduce mortality due to NCDs and increase CVD prevention and management.

Risk Factors for Cardiovascular Disease

There may be a combination of behavioral, metabolic, and other risk factors that lead to the occurrence of cardiovascular disease. Some of these risk factors may be modifiable by adopting healthy behaviors and treatment.

Unhealthy Diet

• The consumption of food that is rich in salt, saturated fat, trans fat, and sugars leads to an increased risk of high blood pressure, poor lipid profile, obesity, and diabetes. This means that a diet containing highly processed foods poses a risk to cardiovascular health.

Physical Inactivity

• Exercise has beneficial effects on cardiovascular health and weight management. Physical inactivity is identified as a risk factor for cardiovascular disease.

Tobacco Usage

• Tobacco usage is associated with an increased risk of cardiovascular disease. There is evidence of causation of coronary heart disease due to tobacco exposure, according to WHO.

High Blood Pressure, Diabetes and High Cholesterol

• High blood pressure, diabetes and abnormal blood lipids are significant cardiovascular disease risk factors. Early diagnosis and adequate treatment of these diseases are crucial for the prevention of CVDs.
• The South-East Asia guidelines published by WHO include the management of high blood pressure and diabetes among the key aspects of cardiovascular disease control.

Obesity, Stress and Alcohol

• Excessive body weight, chronic stress, dangerous alcohol consumption and a sedentary lifestyle may act as additional cardiovascular risk factors especially when these are combined with high blood pressure, diabetes or unhealthy blood lipid level.

Heart Disease Warning Symptoms

Some forms of cardiovascular diseases may have no apparent symptoms, thus making regular health checks necessary. These may include,

• Chest pain: Sensation of pressure, tightness, heaviness or pain in the chest.
• Shortness of breath: Troubled breathing whether during any physical activity or while resting.
• Pain in other body parts: Pain may be felt in the arm, shoulder, neck, jaw or back.
• Extreme tiredness: Unusual or persistent tiredness.
• Rapid heartbeat: Heart racing, palpitation or skipping a beat.
• Dizziness or passing out: Especially if other symptoms are present.
• Swelling: Presence of excess fluid in the feet, ankles or legs.

The symptoms may differ from one person to another. In case of sudden or extreme symptoms, especially chest pain and shortness of breath, one needs medical attention immediately.

Healthy Lifestyle Habits for Heart Health

There are some lifestyle practices which can help in maintaining good heart health.

Heart Healthy Diet

• The diet that can help in keeping the heart healthy includes vegetables, fruits, grains, legumes, nuts, and seeds. Food rich in sodium, fats, and added sugars must be consumed in low quantities.
• Reduced consumption of salt is one of the key factors which have been suggested by WHO to reduce heart disease because high salt intake can lead to high blood pressure.

Physical Activities

• Regular physical activity helps in maintaining good cardiovascular health and also helps in maintaining good body weight. Cycling, walking, and swimming are few physical activities that can be undertaken according to the individual’s health condition.

Quit Tobacco Smoke

• Stopping tobacco smoking and exposure to passive smoking are two vital factors for maintaining heart health.

Control Blood Pressure, Blood Sugar, and Cholesterol Levels

• Health screenings periodically can diagnose hypertension, diabetes and high or low levels of cholesterol. Treatment and lifestyle changes can prevent further risks for the development of cardiovascular diseases.

Sleep and Stress Control

• Healthy sleep and adequate stress management are beneficial to both cardiovascular and metabolic health. Regular sleep and stress relief through activities can prove helpful.

Cardiovascular Disease in the WHO South-East Asia Region

Cardiovascular disease is one of the most important public health problems of the WHO South-East Asia Region. WHO found that hypertension, diabetes, tobacco smoking, poor diet, alcohol consumption and physical inactivity were the major risk factors.

This region has also introduced the SEAHEARTS initiative aimed at faster prevention and control of cardiovascular diseases in South-East Asia. It involves tobacco control, salt reduction, trans fats elimination, and better hypertension and diabetes management.
