OBJECTIVE: The Grenada Heart Project aims to study the clinical, biological, and psychosocial determinants of the cardiovascular health in Grenada in order to develop and implement a nationwide cardiovascular health promotion program. METHODS: We recruited 2,827 adults randomly selected from the national electronic voter list. The main outcome measures were self-reported cardiovascular disease and behavioral risk factors, anthropometric measures, blood pressure, point-of-care testing for glucose and lipids, and ankle-brachial index. Risk factors were also compared with the U.S. National Health and Nutritional Survey data. RESULTS: Prevalence of cardiovascular disease risk factors were: overweight and obesity-57.7% of the population, physical inactivity-23.4%, diabetes-13.3%, hypertension-29.7%, hypercholesterolemia-8.6%, and smoking-7%. Subjects who were physically active had a significantly lower 10-year Framingham risk score (p<0.001). Compared with the U.S. National Health and Nutrition Survey data, Grenadian women had higher rates of adiposity, diabetes, hypertension, and elevated low-density lipoprotein cholesterol, whereas Grenadian men had a higher rate of diabetes, a similar rate of hypertension, and lower rates of the other risk factors. Prevalence of peripheral arterial disease was 7.6%; stroke and coronary heart disease were equally prevalent at approximately 2%. CONCLUSIONS: This randomly selected adult sample in Grenada reveals prevalence rates of obesity, hypertension, and diabetes significantly exceeding those seen in the United States. The contrasting, paradoxically low levels of prevalent cardiovascular disease support the concept that Grenada is experiencing an obesity-related "risk transition." These data form the basis for the implementation of a pilot intervention program based on the Institute of Medicine recommendations and may serve as a model for other low- and middle-income countries.

Noncommunicable diseases, including cardiovascular disease, chronic respiratory disease, diabetes, cancer, and mental illness, are the leading causes of death and disability worldwide. These diseases are chronic and often mediated predominantly by social determinants of health. Currently there exists a global-health workforce crisis and a subsequent disparity in the distribution of providers able to manage chronic noncommunicable diseases. Clinical competency in global health and primary care could provide practitioners with the knowledge and skills needed to address the global rise of noncommunicable diseases through an emphasis on these social determinants. The past decade has seen substantial growth in the number and quality of US global-health and primary-care training programs, in both undergraduate and graduate medical education. Despite their overlapping competencies, these 2 complementary fields are most often presented as distinct disciplines. Furthermore, many global-health training programs suffer from a lack of a formalized curriculum. At present, there are only a few examples of well-integrated US global-health and primary-care training programs. We call for universal acceptance of global health as a core component of medical education and greater integration of global-health and primary-care training programs in order to improve the quality of each and increase a global workforce prepared to manage noncommunicable diseases and their social mediators.

Cardiovascular disease (CVD) is the leading cause of mortality worldwide, with more than 80% of CVD deaths occurring in low- and middle-income countries (LMICs). There have been several calls for action to address the global burden of CVD, but there remains insufficient investment in and implementation of CVD prevention and disease management efforts in LMICs. To catalyze the action needed to control global CVD, the Institute of Medicine recently produced a report, Promoting Cardiovascular Health in the Developing World: A Critical Challenge to Achieve Global Health. This paper presents a commentary of the Institute of Medicine's report, focusing specifically on the intersectoral nature of intervention approaches required to promote global cardiovascular health. We describe 3 primary domains of intervention to control global CVD: 1) policy approaches; 2) health communication programs; and 3) healthcare delivery interventions. We argue that the intersectoral nature of global CVD interventions should ideally occur at 2 levels: first, all 3 domains of intervention must be activated and engaged simultaneously, rather than only 1 domain at a time; and second, within each domain, a synergistic combination of interventions must be implemented. A diversity of public and private sector actors, representing multiple sectors such as health, agriculture, urban planning, transportation, finance, broadcasting, education, and the food and pharmaceutical industries, will be required to collaborate for policies, programs, and interventions to be optimally aligned. Improved control of global CVD is eminently possible but requires an intersectoral approach involving a diversity of actors and stakeholders.

On May 13, 2010, a resolution passed at the United Nations for a high-level meeting with heads of state on noncommunicable chronic diseases (NCDs), catapulting NCDs atop the political and health agendas. This meeting on NCDs, slated for September 2011, provides the rare political moment to commit to scaling up international, regional, and national efforts to prevent and treat NCDs, giving the issue the priority it deserves. An analogous high-profile meeting transpired in 2001 on human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), effectively serving as the nucleating event for a vigorous global and political movement towards universal prevention and treatment. As was the case at the HIV/AIDS meeting, a key priority area in the new NCD movement remains ensuring universal access to reliable, affordable essential medicines to prevent and treat NCDs. The upcoming meeting, therefore, provides the perfect opportunity to capitalize on the increased political and social awareness of NCDs and to apply the lessons learned from the HIV/antiretroviral experience in order to improve access to essential medicines for NCDs. Social mobilization and political advocacy, used in tandem with technical solutions, is an important lesson from the HIV experience, and will likely be important to ensure access to essential medicines for NCDs, including cardiovascular disease. Here, we use cardiovascular disease as a specific case study to examine the issue, outlining early solutions while drawing parallels and analogies to the HIV experience.
