Mean (SD) is shown for age, body mass index and cholesterol levels. Total cholesterol levels were available for 72%–83% of patients, HDL cholesterol levels were available for 65%–69% of patients, and LDL cholesterol levels were available for 52%–55% of patients in each population in 2008 and 2017. Revascularisation includes percutaneous coronary intervention and coronary artery bypass grafting.
CVD, cardiovascular disease; HDL, high-density lipoprotein; IS, ischaemic stroke ; LDL, low-density lipoprotein; MI, myocardial infarction.
