The prevalence of doctor-diagnosed angina in 4314 older adults in China and comparison with the Rose angina questionnaire: The 4 province study (Letter)

Abstract

Non-communicable disease is the leading cause of death globally and cardiovascular disease (CVD) is the major contributor [ 1 ]. China is the most populous country in the world and has been experiencing a progressive increase in CVD, with recent studies showing that 30% of the population in China has ≥ 3 risk factors for CVD [ 2 ]. This effect appears to be more pronounced in urban areas where a western lifestyle has been adopted.
