Despite living with the highest risk factors for heart disease, people in high income countries suffer less from serious cardiovascular disease, says an international study by the global PURE (Prospective Urban Rural Epidemiology ) collaboration and led by McMaster University researchers.
At the same time, the study found that people in low income countries, although living with fewer risk factors for heart disease, have a higher incidence of serious cardiovascular disease including death.
The international research team found risk factors for cardiovascular disease was lowest in low income countries, intermediate in middle income countries and highest in high income countries. However, the incidence of serious cardiovascular disease such as heart attacks, strokes, heart failure and deaths followed the opposite pattern: highest in the low income countries, intermediate in middle income countries and lowest in high income countries. Hospitalizations for less severe cardiovascular diseases were highest in the high income countries.
