Angina is a symptom of coronary heart disease. Based on Population Health Survey 2003/04, 1.6% of Hong Kong people aged 15 and above had doctor-diagnosed coronary heart disease.
An episode of angina typically starts with chest pain or tightness when you are doing some sort of physical exercise. It may feel like a heavy weight or a tightening across your upper chest. Angina pain is especially likely to occur when walking after a meal. Anger or stress also tends to make it worse.
The pain may also be felt in your neck, throat or arms - making you feel that you are choking or that both arms are dead weights. The pain doesn?t usually last for more than a few minutes and goes fairly quickly after resting. Indigestion and angina are often confused. As well as the pain, you may feel breathless, sweaty and have a sense of fear.
Angina affects about one in 50 people. It can often be controlled with a combination of medication and lifestyle changes.
Angina tends to happen when extra demands are placed on the heart, such as when you are exercising or doing physical activity. This is because your heart needs more oxygen at these times.
