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.
多项研究表明,与年轻的老年人相比,百岁老人具有更好的心血管疾病风险状况。一些报告显示,与70岁和80岁的人群相比,心血管疾病(即高血压、糖尿病、心绞痛和/或心肌梗死)在百岁老人中不太常见。为了解释这一现象,越来越多的假说认为,遗传因素和生活方式因素共同作用,使得百岁老人能够克服最常见的死亡原因——心血管事件,从而实现超长寿命。有人认为,老年人群中药物治疗(特别是用于治疗高血压和血脂异常的药物)使用的增加,可能对改善心血管疾病风险状况起到了一定作用,但药物治疗对促进超长寿命的贡献尚未得到证实。此外,由于生活方式健康,百岁老人在年轻时通常需要的药物较少。百岁老人后代中低风险心血管疾病状况的遗传,以及与他们的配偶或没有百岁老人父母的年龄匹配对象相比,该人群中心血管疾病的患病率较低,都证明了遗传因素的重要性。与年龄和性别匹配的对照组相比,百岁老人后代的另一个优势似乎是心血管疾病发病延迟。心血管疾病风险因素反映了有助于长寿的因素。因此,与年轻的老年人相比,这些风险因素在百岁老人中不太普遍也就不足为奇了。
