Muerte prematura: Según las épocas:
Hace un siglo se estableció la edad de jubilación en la época de Bismarck en 65 años porque era lo mas que vivía la mayoría de la gente.
Actualmente la expectativa de vida se acerca a los 80 y hasta 85 años y no es nada raro vivir el siglo y hasta unos 120 años como edad limite real.

Low cardiac function may accelerate brain aging 6 August 2010 Circulation 2010; Advance online publication
A decreased cardiac index (cardiac output) is associated with decreased brain volume – a sign of brain aging.
Dividing the participants into tertiles based on their cardiac index values revealed that those in the bottom (<2.44 l/min/m2) had a 36% lower brain volume, respectively (p=0.04), than those in the top tertile (>2.92 l/min/m2).
These 36% brain volume differences correspond to
1.9-year increases in brain age. The correlation between cardiac index and brain volume was strongest among participants aged <60 years (p=0.01)
This finding suggests that heart and brain health go hand in hand.

Lower intelligence scores were associated with higher rates of cardiovascular disease and total mortality at a greater level of magnitude than found with any other risk factor except smoking.
This relative index of inequality for the top five risk
factors was found to be 5.58 for cigarette smoking, 3.76 for IQ, 3.20 for low income, 2.61 for high systolic blood pressure, and 2.06 for low physical activity.

Can dementia be prevented? Eliminating diabetes and depression, and boosting education, most likely to ward off dementia. BMJ 2010 (August 5);341:c3885
K Ritchie et al enrolled 1433 community dwelling people who lived in the city of Montpellier, France, and who were aged 65 orolder at baseline between 1999 and 2001. Remaining predictors of dementia were crystallisedintelligence (which is based on knowledge and experience—for example, vocabulary and general information (PAF 18%), depression (PAF 10%), fruitand vegetable consumption (PAF 6%), diabetes (PAF 5%), and the presence of the apolipoprotein E (ApoE) 4 allele (PAF 7%).
The results indicate that a theoretical elimination of depression and diabetes and an increase in education, fruit and vegetable consumption would reduce the total burden of dementia by about 21%.
For comparison, a theoretical elimination of the ApoE 4 allele would lead to a reduction of about 7%.
Hypertension and hypercholesterolaemia in midlife are also risk factors for
developing dementia.

Heavy Smoking in Midlife Increased Dementia Risk Two
Decades Later
Heavy smoking in midlife is associated with more than a doubling of
risk for dementia in older age, An ethnically diverse group of some
21,000 adults aged 50 to 60 were interviewed about their smoking
habits between 1978 and 1985. Researchers then assessed the
participants' medical records from 1994 to 2008 and found that a quarter
had developed dementia, Alzheimer disease, or vascular dementia.
In fully adjusted analyses, the risk for dementia rose as the amount
of smoking increased. In particular, participants who smoked more
than two packs a day in midlife had more than twice the risk for
dementia, AD, or vascular dementia two decades later, compared
with those who'd never smoked.
"It is well recognized that smoking augments oxidative stress and
inflammation, which are also believed to be important pathophysiologic
mechanisms in AD."

(poco antes de morir)
Longevity is a vascular question, which has been well expressed in the axiom that man is only as old as his arteries. To a majority of men death comes
primarily or secondarily through this portal. The onset of what may be called physiological arterio-sclerosis depends, in the first place, on the quality of arterial tissue which the individual has inherited, and secondarily on the amount of wear and tear to which he has subjected it.

Década de los 90: IMC y Score de Riesgo de Framingham (FRS) se vuelven de uso común.
La FC en reposo apenas se menciona como Factor de Riesgo y el IMC se considera FR de segundo rango.
Lancet 13 de Marzo 1999: E. Sánchez-Delgado publicasus resultados preliminares con el Índice Pulso Masa (IMC.FCR/1730), mayor de 1.3 como predictor de riesgo cardiovascular, demostrando su elevada correlación con el FRS (Framingham).
También lo menciona como elemento a considerar para los beneficios o riesgos de fármacos cardiovasculares y metabólicos.

Remarkable success in reducing MI in UKEuropean Heart Journal. June 8, 2011
9453 men and women in British civil servants had a drop of almost 75% in MIs over a 20-year period, attributed mainly to better lifestyle and treatment of risk factors.
They are health conscious, they want to remain in the study, and they are having five-yearly screening check-ups .
There was also a modest contribution from increased consumption of fruit and vegetables.
Over half of this reduction (56%) could be explained by improvements in four of the main risk factors for MI: declining levels of non-HDL cholesterol, an increase in HDL cholesterol, reduced blood pressure, and a reduction in the number of people who smoked.
At the same time, there was a steady annual rise in BMI for both men and women, and this was associated with an increase in the risk of heart attack of 11% over the 20-year period. There will inevitably be an age-associated rise in MI as this cohort grows older

Walking speed linked to adverse outcome risk after cardiac surgery
12 November 2010 J Am Coll Cardiol 2010; 56: 1668–1676
All patients…76 y… were timed while walking a distance of 5 meters, and classified
…as slow (n=60; walked 5 meters in ≥6 seconds) or normal walkers (n=71; walked 5 meters in <6 seconds).
slow gait speed remained significantly associated with a 3.05-fold increased risk for postoperative mortality or major morbidity.
IQ ranks among the strongest predictors of cardiovascular disease, and is second only to cigarette smoking ESC Britain's Medical Research Council 100210
Lower intelligence scores were associated with higher rates of cardiovascular disease and total mortality at a greater level of magnitude than found with any other risk factor except smoking.
The relative strengths of the association were measured by an "index of inequality", which summarised the relative risk of a health outcome
(cardiovascular death) in the most disadvantaged (high risk) people relative to the most advantaged (low risk).
This relative index of inequality for the top five risk
factors was found to be 5.58 for cigarette smoking, 3.76 for IQ, 3.20 for low income, 2.61 for high systolic blood pressure, and 2.06 for low physical activity.

Telomere Length and Risk of Incident Cancer and Cancer Mortality
JAMA. 2010.0707;304(1):69-75.
Context Telomeres are essential to preserve the integrity of the genome. Critically short telomeres lead to replicative cell senescence and chromosomal instability and may thereby increase cancer risk.
Objective To determine the association between baseline telomere length and incident cancer and cancer mortality.
Design, Setting, and Participants Leukocyte telomere length was measured by quantitative polymerase chain reaction in 787 participants free of cancer at baseline in 1995 from the prospective, population-based Bruneck Study in Italy.
Main Outcome Measures Incident cancer and cancer mortality over a follow-up period of 10 years (1995-2005 with a follow-up rate of 100%).
Results A total of 92 of 787 participants (11.7%) developed cancer (incidence rate, 13.3 per 1000 person-years). Short telomere length at baseline was associated with incident cancer independently of standard cancer risk factors (multivariable hazard ratio [HR] per 1-SD decrease in loge-transformed telomere length, 1.60; 95% confidence interval [CI], 1.30-1.98; P < .001). Compared with participants in the longest telomere length group, the multivariable HR for incident cancer was 2.15 (95% CI, 1.12-4.14) in the middle length group and 3.11 (95% CI, 1.65-5.84) in the shortest length group (P < .001).
Incidence rates were 5.1 (95% CI, 2.9-8.7) per 1000 person-years in the longest telomere length group, 14.2 (95% CI, 10.0-20.1) per 1000 person-years in the middle length group, and 22.5 (95% CI, 16.9-29.9) per 1000 person-years in the shortest length group. The association equally applied to men and women and emerged as robust under a variety of circumstances. Furthermore, short telomere length was associated with cancer mortality (multivariable HR per 1-SD decrease in loge-transformed telomere length, 2.13; 95% CI, 1.58-2.86; P < .001) and individual cancer subtypes with a high fatality rate.
Conclusion In this study population, there was a statistically significant inverse relationship between telomere length and both cancer incidence and mortality.
Assessment age important in early atherogenic risk prediction
Markus Juonala et al 30 November 2010 Circulation 2010; Advance online publication
Data were analyzed on 4380 participants aged 3–18 years from the Cardiovascular Risk in
Young Finns Study
Carotid IMT measurements were available. Childhood risk factors comprised being in the highest quintile for total cholesterol, triglycerides, blood pressure, and body mass index (BMI)
…see Pulse Mass Index and Pulse Mass Pressure Product.
Odds ratios for childhood risk score in predicting high IMT in adulthood were higher with increasing age, at 1.37, 1.48, 1.56, and 1.57
for ages 9, 12, 15, and 18 years, respectively. risk factor measurements
are the most useful after the age of 9 years.
The ability to impact lifestyle might be greater at younger ages.
