Hypertension and Cardiovascular Risk Profile in a Middle-Income Setting: The HELISUR Study.

BACKGROUND

Hypertension is the leading risk factor responsible for premature death worldwide, but its burden has shifted to low- and middle-income countries. Therefore, we studied hypertension and cardiovascular risk in the population of Suriname, a middle-income country with a predominantly urban population of African and Asian ancestry.

METHODS

A random sample of 1,800 noninstitutionalized men and women aged 18-70 years was selected to be interviewed at home and examined at the local hospital for cardiovascular risk factors, asymptomatic organ damage, and cardiovascular disease.

RESULTS

The 1,157 participants examined (37% men) were mainly of self-defined Asian (43%) or African (39%) ancestry, mean age 43 years (SD 14). The majority of the population (71%) had hypertension or prehypertension, respectively, 40% and 31%. Furthermore, 72% was obese or overweight, while 63% had diabetes or prediabetes. Only 1% of the adult population had an optimal cardiovascular risk profile. Hypertension awareness, treatment, and control were respectively 68%, 56%, and 20%. In line with this, 22% of the adult population had asymptomatic organ damage, including increased arterial stiffness, left ventricular hypertrophy, microalbuminuria, or asymptomatic chronic kidney disease.

CONCLUSIONS

In this first extensive cardiovascular assessment in the general population of this middle-income Caribbean country, high prevalence of hypertension with inadequate levels of treatment and control was predominant. The findings emphasize the need for collaborative effort from national and international bodies to prioritize the implementation of affordable and sustainable public health programs that combat the escalating hypertension and cardiovascular risk factor burden.
