Objective: To explore possible differences in case fatality after a major coronary (fatal or non-fatal MI, sudden death) or cerebrovascular (fatal of non-fatal stroke) event in different regions of the world according to country’s geographical region and income level. Method: We studied ADVANCE and TECOS participants who experienced a major coronary or cerebrovascular event during these two trials, with countries grouped by: 1) Geographical region; 2) World Bank income levels and examined all-cause mortality that occurred within 30 days after the event. We used logistic regression to derive odds ratios for fatal events, controlling for previous complications and for a range of clinical risk factors. Results: Both studies showed that people from Asia and Central/Eastern Europe (compared with the reference group of Western Europe, North America, Australia and New Zealand), and people from low and middle income countries (compared with those from high income countries), had significantly higher odds of dying within 30 days after a major coronary event but not a major cerebrovascular event (Table).
