Randomized trial of low carbohydrate high fat dietary pattern

There is a need for a large, simple, hard outcome trial of dietary advice to measure the effects of lowering simple carbohydrates versus lowering unhealthy fats. The main challenge will be to overcome bias favoring the more conventional dietary approach.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

Substantial numbers are moving towards low carbohydrate/high fat diets to the extent that since 2000 the macronutrient composition of the US diet has changed towards lower carbohydrate and higher fat intakes; however, CV mortality rates continue to decline. The outcome of the trial will help frame future guidelines for healthy diets.

Feasibility and challenges of addressing this CQ or CC :

Yes, since computer or smartphone based intervention materials and passive outcome collections (CMS, NDI, health care organizations) are increasingly being utilized.

Low carbohydrate high fat (LCHF) diets first popularized for weight reduction are increasingly being promoted to prevent diabetes and cardiovascular disease. All trials to date have been small and short term. Compared to more traditional high carbohydrate low fat diets, LCHF diets may be somewhat more beneficial for weight control, glucose homeostasis, and dyslipidemia, but less beneficial for LDL reduction.

New ideas from drug-induced cardiotoxicity

What are the fundamental mechanisms of drug, chemical, or biologics-induced cardiotoxicity (e.g., which proteins or signaling targets are most vulnerable)? Would such knowledge lead to understanding of the most critical signaling systems and contribute to development of new therapeutic (cardioprotective) strategies?

Submitted by (@nhlbiforumadministrator1)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

Beyond helping with real-world problems (e.g., cancer drug cardiotoxicity), understanding of toxicity mechanisms in the CV system enables a different level of understanding. For example, acute toxicity testing is probably akin to crash testing of the CV system, permitting us to see where things break. Thus there is potential to lead to a fuller understanding and novel therapeutic ideas.

Feasibility and challenges of addressing this CQ or CC :

As the number of newer and more powerful therapeutics grow, their risk of adverse impact on the CV system grows. This is in part due to insufficient knowledge of toxicity mechanisms and lack of effective drug-screening tools during drug development. This field primarily lacks researchers.

Development of non-contrast alternatives in cardiac magnetic resonance imaging

Critical Challenge

Submitted by (@str0001)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

Late gadolinium-enhancement cardiac magnetic resonance imaging (MR) plays a crucial role in the evaluation of patients with suspected myocardial scar tissue. Alternative methods to contrast-enhanced MR however are in need, given the number of patients who have concomitant compromised renal function and concern for nephrogenic systemic fibrosis. Noncontrast MR techniques such as diffusion-weighted imaging would complement and eventually replace gadolinium administration thus impacting the evaluation of those with suspected and confirmed infiltrative cardiac processes and systemic diseases.

Feasibility and challenges of addressing this CQ or CC :

Late gadolinium enhancement technique characterizes enhancement patterns of heart disease, identifies areas amenable to ablation, and aids in decisions pertaining to workup and therapy. The underlying mechanism of Brownian motion/diffusion in the expanded extracellular space makes diffusion weighted imaging a potential gadolinium-saving modality. Diffusion MR, applied primarily in the brain and abdominal imaging, is underutilized in the heart given respiratory and cardiac motion. A need exists to further develop and apply noncontrast MR techniques towards cardiovascular applications. Such methods are promising noncontrast alternatives to characterize patients with myocardial disease, determine those with differing prognoses, and direct appropriate therapies to subgroups.

Cardiometabolic Disease Risks Associated with Sleep Deficiency

How does insufficient sleep duration, irregular timed sleep schedules, and poor sleep quality contribute to the pathophysiology of lung, heart and blood diseases?

Submitted by (@nhlbiforumadministrator)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

Sleep deficiency and untreated sleep disorders threaten the health of 20-30 percent of US adults through an increased risk of stroke, hypertension, diabetes, inflammatory disease, and all-cause mortality. Developing the scientific evidence-base of validated interventions will enhance the management of cardiometabolic and pulmonary risks to health, present new opportunities for secondary prevention, and reduce associated burden on health care systems.

Feasibility and challenges of addressing this CQ or CC :

Improving sleep health through informed public recognition of decision-relevant science, and relatively low cost therapies for management of sleep disorders are available for immediate assessment of impact in appropriate clinical trials to demonstrate efficacy and effectiveness.

Discovery research advances implicate an array of cellular sleep and circadian mechanisms in pathophysiological pathways leading to cardiometabolic and pulmonary disease.

 

Irregular and disturbed sleep impairs cellular biological rhythm in all tissues and organs leading to oxidative stress, unfolded protein responses, and impaired cell function. The pathophysiological findings juxtaposed with epidemiological evidence of disease risk indicate that sleep deficiency contributes to an erosion of health across the lifespan over and above the effects of aging.

Treating cardiovascular disease in persons with mental health disorders

How can we most effectively prevent and treat cardiovascular disease among persons with serious mental disorders?

Submitted by (@nhlbiforumadministrator)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

Clinical anxiety disorders affects 40 million people in the US and the lifetime prevalence of PTSD is 6-8%,. The incidence of PTSD in particular is rapidly expanding in the US; this condition doubles the risk of a cardiac event.

 

The prevalence rates are higher in some populations; 3 out of 10 US military veterans have a diagnosis of PTSD, and many more are undiagnosed. Among patients at a VA, a diagnosis of PTSD increased the probability of circulatory problems (odds ratio 3.7). In another study, every additional PTSD symptom increased the risk of developing cardiovascular disease by 17%. Thus, the impact of developing more effective treatments adapted to the needs of this vulnerable population could be significant.

Feasibility and challenges of addressing this CQ or CC :

As the incidence of many mental health disorders such as PTSD and depression increases, the need for developing and adapting treatments for this population becomes critical.

 

Effective treatments may not be optimal for persons with serious mental illnesses and strategies to tailor treatments to the challenges of this vulnerable population are needed.

Individuals with mental illnesses such as major depressive disorder, bipolar disorder, and anxiety disorders are at significantly higher risk for cardiovascular disease than are those without these illnesses. Those with serious mental illnesses die an average of 25 years earlier, frequently from cardiovascular disease. The incidence of PTSD is rapidly expanding in the US; this condition doubles the risk of cardiovascular events.

Understanding the Role of the Vasculature in Dementia

Dementia is traditionally grouped into vascular dementia, Alzheimer's dementia, Parkinson's dementia and other causes of dementia. Vascular dementia is generally thought to be a consequence of strokes but there are some recent studies indicating that even Alzheimer's dementia may have a vascular underpinning. Vascular permeability is increased in the early stages of Alzheimer's disease and it is possible that similar ...more »

Details on the impact of addressing this CQ or CC :

The NHLBI could fund programs which enable vascular biologists to collaborate with neuroscientists and neurologists in order to understand whether the vasculature has a causal role in the progression of dementia.

 

 

 

Can interventions that improve vascular function prevent the progression of dementia? Instead of using broad interventions such as statins which affect numerous signaling pathways, vascular biologists could target selected aspects of vascular health such as improving vascular barrier function and vascular regeneration.

 

If these interventions that have been shown to be efficacious in other vascular beds outside of the brain are also effective in the brain, then important new therapies could be developed for dementia which is likely to become one of the leading cause of death in the next decades.

Feasibility and challenges of addressing this CQ or CC :

A key challenge for targeting the brain vasculature will be the blood-brain barrier. Understanding the role of the blood-brain barrier in dementia will be a prerequisite to developing novel vasculature-directed therapies.

Early prediction of cardiovascular disease by primary-care assessment

Tools for early assessment of cardiovascular disease have become available but not adopted in primary-care settings. Increased arterial stiffness is a well-known marker for advanced cardiovascular disease (CVD) and has been shown to be an independent predictor of cardiovascular mortality. In addition, arterial pulse wave velocity (PWV) has been readily accepted as a measure of arterial stiffness. Despite significant ...more »

Submitted by (@roy.wallen)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

In the US, 84 million adults will see their primary care physician for treatment of cardiovascular disease (CVD). CVD is responsible for an average of one death every 40 seconds. The direct and indirect costs of cardiovascular disease and stroke are approximately $315 billion, including the cost of health care services, medications to treat high blood pressure, and missed days of work. The World Health Organization states that 80% of premature heart disease and stroke is preventable. Focusing on assessing risk factors for cardiovascular disease, screening for individuals at risk, and then providing effective and affordable treatment to those who require it can prevent disability and death and improve quality of life.

 

In Europe, the European Society of Cardiology (ESC) has issued guidelines based on the weight of evidence in favor of the usefulness of screening for CVD by assessing arterial stiffness. These guidelines are supported by nonrandomized trials and suggest the development of randomized trials or meta-analyses. However, no guidelines exist in the US for screening for arterial stiffness from such organizations as the American Heart Association (AHA) and the American College of Cardiology (ACC). Existing guidelines to include assessment of cholesterol, lifestyle, obesity, and factors for risk are important. However, a simple, low-cost, objective measurement could be implemented at the point of primary care to improve early detection and treatment of CVD.

Feasibility and challenges of addressing this CQ or CC :

Screening capabilities and some level of clinical evidence exist for early detection of CVD. Therefore, implementation of a practice guideline in the US is very feasible. Studies and assessment from existing data such as have been completed by ESC can be replicated in the US and promulgated by AHA and ACC. This effort will require support from public and private entities, including universities, in order to see practice standards implemented.

 

Challenges to date include funding and the application of clinical protocols to support randomized studies or meta-analyses that will provide evidence for benefits of early screening. Further, public policy and current funding are focused on treatment rather than prevention. Existing reimbursement established by the Centers for Medicare & Medicaid Services (CMS) is focused on treatment rather than prevention and private insurance carriers have followed this same policy. Broader clinical study will support both the adoption of screening tools in primary care and broader reimbursement policy.

SLEEP DISORDERS AS A MODIFIABLE RISK FACTOR FOR CHRONIC DISEASE

There is developing evidence that sleep disorders, in particular obstructive sleep apnea and inadequate sleep, can influence the course of other chronic diseases. Observational studies show that CPAP treatment of patients with pre-diabetes who have OSA reduces the incidence of future diabetes. Moreover, animal and human data indicate that insufficient sleep and sleep apnea can affect the rate of progression of neurodegenerative ...more »

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

This question will have considerable impact. Sleep apnea is an independent risk factor for insulin resistance. Moreover, observational studies show that treatment of OSA reduces the rate of future diabetes compared to that which occurs in untreated OSA. Therefore, identifying OSA and treating this could have a profound impact on reducing the rate of diabetes, i.e., a preventative strategy.

 

Both sleep loss and obstructive sleep apnea have also been shown to be risk factors for subsequent development of Alzheimer’s disease. This has been shown in mouse models and in epidemiological studies to address whether insufficient sleep and sleep apnea are independent risk factors for development of Alzheimer’s disease, in particular accelerating their onset. Determining whether this is so and whether interventions to treat these sleep disorders delay onset of diabetes and Alzheimer’s disease would have profound public health significance.

Feasibility and challenges of addressing this CQ or CC :

These disorders are extremely common so that recruitment of subjects is not challenging. Moreover, new technology reduces protocol burden to assess individuals. All studies can be done in the patients’ home. There are existing cohort studies focused on diabetes and the Alzheimer’s Center program that could be used for these studies. Thus, the studies are extremely feasible in the near term.
