Categorical data are presented as yes (Y) or no (N), unless otherwise indicated. Echocardiography (Echo) data: left ventricular ejection fraction (LVEF), left ventricular internal diameter in diastole (LVIDd), left ventricular internal diameter in systole (LVIDs), mitral valve inflow measured as ratio of peak velocity flow in early diastole (E) compared to late diastole (A) caused by atrial contraction (E/A) ratio. Atrial fibrillation* refers to any present or previous history of atrial fibrilation. Quantitative data represented as mean ±s.d. CH, Chinese; Ex, ex-smoker; IN, Indian sub- continent; MY, Malaysian.
