More Aggressive Control of Blood Pressure Modestly Extends Life in Older People

Hypertension, the widespreak age-related increase in blood pressure, is very damaging. It is one of the major ways in which low-level biochemical damage, leading to stiffening of blood vessels and consequent disruption of the feedback mechanisms that determine blood pressure, gives rise to structural tissue damage throughout the body. Hypertension harms delicate tissues in the brain, kidneys, and elsewhere. Hypertension also speeds the development of atherosclerosis, the formation of fatty lesions in blood vessel walls, and makes it more likely that blood vessels weakened by plaques will rupture, leading to a heart attack or stroke. These and other mechanisms are why control of blood pressure, without controlling the underlying causes of hypertension, has a measurable effect on life expectancy. Globally, an estimated 1.13 billion people have high blood pressure, or hypertension, which causes about 13% of all deaths, according to the World Health Organization. Almost 1,000 people in the U.S. die each day with high blood pressure as a primary or contributing cause, according to data from the Centers for Disease Control and Prevention. The research into hypertension care and life span found that with more intensive blood pressure control, focused on a target systolic blood pressure of less than 120 mmHg, a 50-year-old could expect to live almost three years longer. In order to achieve the lower blood pressure target, patients adopted healthy lifestyle habits and took bl...

AbstractVitamin C (Vit C) is an ideal antioxidant as it is easily available, water soluble, very potent, least toxic, regenerates other antioxidants particularly Vit E, and acts as a cofactor for different enzymes. It has received much attention due to its ability in limiting reactive oxygen species, oxidative stress, and nitrosative stress, as well as it helps to maintain some of the normal metabolic functions of the cell. However, over 140 clinical trials using Vit C in different pathological conditions such as myocardial infarction, gastritis, diabetes, hypertension, stroke, and cancer have yielded inconsistent results....

This study is the first to provide a direct link between this inflammation and plaque development - by way of IFITM3. Scientists know that the production of IFITM3 starts in response to activation of the immune system by invading viruses and bacteria. These observations, combined with the new findings that IFITM3 directly contributes to plaque formation, suggest that viral and bacterial infections could increase the risk of Alzheimer's disease development. Indeed, researchers found that the level of IFITM3 in human brain samples correlated with levels of certain viral infections as well as with gamma-secretase activ...

CONCLUSIONS: We found there is probably little to no difference in total mortality and cardiovascular mortality between people with hypertension and cardiovascular disease treated to a lower compared to a standard blood pressure target. There may also be little to no difference in serious adverse events or total cardiovascular events. This suggests that no net health benefit is derived from a lower systolic blood pressure target. We found very limited evidence on withdrawals due to adverse effects, which led to high uncertainty. At present, evidence is insufficient to justify lower blood pressure targets (135/85 mmHg or le...

The raised blood pressure of hypertension causes harm throughout the body, raising mortality risk and accelerating the onset and progression of numerous forms of ultimately fatal age-related disease. It accelerates atherosclerosis, and raises the risk of a fatal rupture of blood vessels weakened by atherosclerotic lesions. It causes pressure damage to delicate tissues throughout the body. It leads to detrimental remodeling of heart tissue and the onset of heart failure. Thus forcing a reduction in blood pressure is quite beneficial in later life, even when it is achieved - as is presently the case - by overriding regulator...

Hypertension is a worldwide known cause of morbidity and mortality in the elderly and is a major risk factor for cardiovascular complications such as stroke, myocardial infarction, renal complications and heart failure. Although the mechanisms of hypertension remain largely unknown, a recent new concept is that aortic stiffening is a cause of hypertension in middle-aged and older individuals, which highlighted the importance of aortic stiffening in the development of age-related hypertension. Understanding the pathogenesis of aortic stiffness therefore became one of the important approaches to preventing and controlling hy...

Conclusions: ISCHEMIA trial participants with stable ischemic heart disease and at least moderate ischemia with a history of HF or LVD were at increased risk for the primary outcome. In the small, high-risk subgroup with HF and LVEF 35-45%, an initial invasive approach was associated with a better event-free survival. This result should be considered hypothesis generating.

“Doctor, can you take away any of my medications? I am taking too many pills.” As physicians, we hear this request frequently. The population most affected by the issue of being prescribed multiple medications, known as polypharmacy, is the elderly. Trying to organize long lists of medications, and remembering to take them exactly as prescribed, can become a full-time job. In addition to the physical and emotional burden of organizing medications, older adults are at increased risk for certain types of side effects and potential worse outcomes due to polypharmacy. A common source of prescriptions is high blood ...

In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, C...

Conclusion: Compared with other antihypertensive agents, beta-blockers appear to be substantially less protective against stroke and overall mortality. However, they exhibit a substantial risk-reducing ability for all events when prescribed to lower BP in patients with modest or more clear BP elevations, and therefore can be used as additional agents in hypertensive patients.

AbstractBackgroundPatients with diabetes who had a recent myocardial infarction (MI) are at high risk of cardiovascular events. Therefore, risk assessment is important for treatment and shared decisions. We used data from EXAMINE trial to investigate whether a multi-proteomic approach would provide specific proteomic signatures and also improve the prognostic capacity for determining the risk of cardiovascular death, MI, stroke, heart failure [HF], all-cause death, and combinations of these outcomes.Methods93 circulating proteins (92 from the Olink ® CVDII plus troponin) were assessed in 5131 patients. Cox, competing r...
