Hypertension (HT), a common age-related disorder, is an important risk factor for cardiovascular disease. This study aims to identify the prevalence of HT in Portuguese centenarians and evaluate whether gene polymorphisms encoding key molecules in blood pressure (BP) regulation are associated with longevity. There were recruited 253 centenarians (100.26 ± 1.98 years) and 268 control subjects (67.51 ± 3.25 years). Hypertension (ESH/ESC2013 and JNC8) and diabetes (WHO) were evaluate. Genetic polymorphisms of renin-angiotensin-aldosterone system (RAAS) and NOS3 were determined. The prevalence of HT among centenarians was 64.4% and the majority (58.9%) were controlled, differing from control group both on frequency ( P  < 0.001) and on their control ( P  < 0.001). We found that HT is a risk factor for not achieving longevity (OR 2.531, 95% CI 1.688–3.793, P  < 0.001), the same for diabetes (OR 5.669 95% CI 2.966–10.835, P  < 0.001), and male gender (OR 2.196, 95% CI 1.493–3.29, P  < 0.001). Hypertension, adjusted for gender and diabetes, was independent risk factor anti-longevity (OR 2.007, 95% CI 1320–3.052, P  = 0.001). The ACE_D and NOS3_G alleles were more frequent in centenarians compared to controls ( P  < 0.001, both cases). ACE_II and NOS3_TT genotypes, adjusted for BP, gender and diabetes, increased risk in 3.748 (95% CI 1.887–7.444) and 2.533 (95% CI 1.483–4.327), respectively, in relation to ACE_DD ( P  < 0.001) and NOS3_GG ( P  = 0.001), against longevity. Our findings suggest that the prevalence of hypertension was lower in Portuguese centenarians than in the elderly, reinforcing the importance of better cardiovascular risk profiles to achieve longevity even in the presence of genetic condition.
