Background: Atherothrombosis is becoming the leading cause of chronic morbidity in developing countries. This epidemiological transition will represent an unbearable socioeconomic burden in the near future. We investigated factors associated with 4-year all-cause mortality in a Latin American population at high risk. Hypothesis: Largely modifiable risk factors as well as polyvascular disease are the main predictors of 4-year all-cause and cardiovascular mortality in this Latin American cohort. Methods: We analyzed 1816 Latin American stable outpatients (62.3% men, mean age 67 years) with symptomatic atherothrombosis (87.1%) or with multiple risk factors only (12.9%), in the Reduction of Atherothrombosis for Continued Health registry. Results: Of patients with symptomatic atherothrombosis, 57.3% had coronary artery disease, 32% cerebrovascular disease, and 11.7% peripheral artery disease at baseline (9.1% polyvascular). The main risk factors were hypertension (76%), hypercholesterolemia (60%), and smoking (52.3%) in patients with established atherothrombosis; and hypertension (89.7%), diabetes (80.8%), and hypercholesterolemia (73.9%) in those with risk factors only. Four-year all-cause mortality steeply increased with none (6.8%), 1 (9.2%), 2 (15.5%), and 3 (29.2%) symptomatic arterial disease locations. In patients with only 1 location, cardiovascular mortality was significantly higher with peripheral artery disease (11.3%) than with cerebrovascular disease (6%) or coronary artery disease (5.1%). Significant baseline predictors of 4-year all-cause mortality were congestive heart failure (hazard ratio [HR]: 3.81), body mass index <20 (HR: 2.32), hypertension (HR: 1.84), polyvascular disease (HR: 1.69), and age =65 years (HR: 1.47), whereas statin use (HR: 0.49) and body mass index =30 (HR: 0.58) were associated with a reduced risk. Conclusions: Hypertension was the main modifiable risk factor for atherothrombosis and all-cause mortality in this Latin American cohort. Nearly one-third of the population with 3 symptomatic vascular-disease locations died at 4-year follow-up.
