摘要：Objectives To determine the feasibility of assessing population cardiovascular risk with advanced hemodynamics in the Healthy Life in Suriname (HELISUR) study. Methods This was a preliminary study conducted in May – June 2012 using the Technical-Economic-Legal-Operational-Scheduling (TELOS) method to assess the feasibility of the HELISUR—a large-scale, cross-sectional population study of cardiovascular risk factors and disease in Suriname. Suriname, a middle-income country in South America with a population of mostly African and Asian ethnicity, has a high risk of cardiovascular disease. A total of 135 volunteers 18 – 70 years of age participated. A health questionnaire was tested in a primary health care center, and non-invasive cardiovascular evaluations were performed in an academic health center. The cardiovascular evaluation included sitting, supine, and standing blood pressure, and intermediate endpoints, such as cardiac output, peripheral vascular resistance, pulse wave velocity, and augmentation index. Results The TELOS testing found that communicating by cellular phone was most effective for appointment adherence, and that completion of the questionnaire often required assistance from a trained interviewer; modifications to improve the clarity of the questions are recommended. Regarding the extended cardiovascular assessments of peripheral and central hemodynamics, the findings showed these to be technically and operationally feasible and well tolerated by participants, in terms of burden and duration. Conclusions Findings of this feasibility assessment indicate that large-scale, detailed evaluations of cardiovascular risk, including a questionnaire and advanced central and peripheral hemodynamics, are feasible in a high-risk population in a middle-income setting.
