Cardiovascular risk factors in centenarians.

Several studies have shown that centenarians have better cardiovascular risk profiles compared to younger old people. Some reports have revealed that cardiovascular diseases (i.e. hypertension, diabetes, angina and/or myocardial infarction) are less common in centenarians respect to 70 and 80 years old persons. In order to explain this evidence, there is a growing number of hypothesis that consider a combination of genetic factors and lifestyle aspects to elucidate the exceptional longevity of centenarians, able to overcome the most frequent mortality cause, which is a cardiovascular event. It has been suggested that a role on this better cardiovascular risk profile may be played by the increasing use of pharmacologic treatments in the elderly population (specially for hypertension and dyslipidemia), but the contribution of drug treatments to promote extreme longevity is not confirmed. Furthermore, centenarians in general have needed fewer drugs at younger ages due to a healthy lifestyle. The importance of the genetic contribution is demonstrated by the inheritance of low-risk cardiovascular profiles in centenarian offspring and lower prevalence of cardiovascular diseases in this population as compared with their spouses or with age-matched subjects without centenarian parents. Another advantage in centenarians' offspring seems to be a delay in the onset for cardiovascular diseases, respect to age- and sex-matched controls. Cardiovascular risk factors mirror the factors that contribute to longevity. Hence, it is not surprising that these risk factors are less prevalent in centenarians when compared to younger old individuals.
