Health Studies: Early Heart Disease Is Related More To Poor Lifestyle Choices Than Genetics

From a ScienceDaily.com online release:

Eurpean Society of CardiologyPhysical inactivity, smoking, high blood pressure, diabetes, and high cholesterol play a greater role than genetics in many young patients with heart disease, according to research presented today at ESC Congress 2019 together with the World Congress of Cardiology. The findings show that healthy behaviours should be a top priority for reducing heart disease even in those with a family history of early onset.

The study enrolled 1,075 patients under 50, of whom 555 had coronary artery disease (known as premature CAD). Specific conditions included stable angina, heart attack, and unstable angina. The average age was 45 and 87% were men. Risk factor levels and genetics in patients were compared to a control group of 520 healthy volunteers (average age 44, and 86% men). Patients and controls were recruited from the Genes in Madeira and Coronary Disease (GENEMACOR) database.

Five modifiable risk factors were assessed: physical inactivity, smoking, high blood pressure, diabetes, and high cholesterol. Nearly three-quarters (73%) of patients had at least three of these risk factors compared to 31% of controls. In both groups, the likelihood of developing CAD increased exponentially with each additional risk factor. The probability of CAD was 3, 7, and 24 times higher with 1, 2, and 3 or more risk factors, respectively.

Health Studies: High Levels Of Optimism Can Increase Men’s & Women’s Lifespans By Up To 15%

From a PNAS.org online release:

Optimism Study PNASOur results further suggest that optimism is specifically related to 11 to 15% longer life span, on average, and to greater odds of achieving “exceptional longevity,” that is, living to the age of 85 or beyond. These relations were independent of socioeconomic status, health conditions, depression, social integration, and health behaviors (e.g., smoking, diet, and alcohol use). Overall, findings suggest optimism may be an important psychosocial resource for extending life span in older adults.

Participants with highest versus lowest optimism levels had 1.5 (women) and 1.7 (men) greater odds of surviving to age 85; these relationships were maintained after adjusting for health behaviors. Given work indicating optimism is modifiable, these findings suggest optimism may provide a valuable target to test for strategies to promote longevity.

Health Studies: Patients With Gout Face Double The Risk Of Kidney Failure

From a  Eurekalert.org online release:

Gout Study - Increased Kidney Failure Risk UL“While we always believed that high levels of uric acid might be bad for kidneys and that patients with gout may have a higher risk of kidney failure, we were quite surprised by the magnitude of the risk imposed by gout in these patients. We were particularly interested in the risk of advanced kidney disease, as these patients in general have a higher risk of kidney failure and death.

Patients with gout are at increased risk of chronic kidney disease and kidney failure, according to new University of Limerick (UL), Ireland led research.

In one of the largest and most detailed studies ever conducted, patients recruited in general practice with a diagnosis of gout were more than twice as likely to develop kidney failure than those without, according to the study led by researchers at University of Limerick’s (UL) Graduate Entry Medical School (GEMS).

Drug Studies: Polypill Strategy (Including Aspirin) Proves “Effective In Preventing Major Cardiovascular Events”

From The Lancet issue August 24, 2019:

Polypill illustration from Harvard HealthUse of polypill was effective in preventing major cardiovascular events. Medication adherence was high and adverse event numbers were low. The polypill strategy could be considered as an additional effective component in controlling cardiovascular diseases, especially in LMICs.

When restricted to participants in the polypill group with high adherence, the reduction in the risk of major cardiovascular events was even greater compared with the minimal care group…

A fixed-dose combination therapy (polypill strategy) has been proposed as an approach to reduce the burden of cardiovascular disease, especially in low-income and middle-income countries (LMICs). The PolyIran study aimed to assess the effectiveness and safety of a four-component polypill including aspirin, atorvastatin, hydrochlorothiazide, and either enalapril or valsartan for primary and secondary prevention of cardiovascular disease.

Health Studies: Physician Prescribed Omega-3 Fatty Acids Safely Reduce High Triglyceride Levels

From the journal Circulation on August 19, 2019:

Circulation JournalThe use of n-3 FA (4 g/d) for improving atherosclerotic cardiovascular disease risk in patients with hypertriglyceridemia is supported by a 25% reduction in major adverse cardiovascular events in REDUCE-IT (Reduction of Cardiovascular Events With EPA Intervention Trial), a randomized placebo-controlled trial of EPA-only in high-risk patients treated with a statin.

The results of a trial of 4 g/d prescription EPA+DHA in hypertriglyceridemia are anticipated in 2020. We conclude that prescription n-3 FAs (EPA+DHA or EPA-only) at a dose of 4 g/d (>3 g/d total EPA+DHA) are an effective and safe option for reducing triglycerides as monotherapy or as an adjunct to other lipid-lowering agents.

Hypertriglyceridemia (triglycerides 200–499 mg/dL) is relatively common in the United States, whereas more severe triglyceride elevations (very high triglycerides, ≥500 mg/dL) are far less frequently observed. Both are becoming increasingly prevalent in the United States and elsewhere, likely driven in large part by growing rates of obesity and diabetes mellitus.

Health Studies: Scientists At Rutgers Discover How Brown Fat Protects Against Obesity & Diabetes

From a Rutgers Today online article:

The study found that brown fat could also help the body filter and remove branched-chain amino acids (BCAAs) from the blood. BCAAs (leucine, isoleucine and valine) are found in foods like eggs, meat, fish, chicken and milk, but also in supplements used by some athletes and people who want to build muscle mass.

Rutgers Brown Fat Study

In normal concentrations in the blood, these amino acids are essential for good health. In excessive amounts, they’re linked to diabetes and obesity. The researchers found that people with little or no brown fat have reduced ability to clear BCAAs from their blood, and that may lead to the development of obesity and diabetes.

Rutgers and other scientists have discovered how brown fat, also known as brown adipose tissue, may help protect against obesity and diabetes. Their study in the journal Nature adds to our knowledge about the role of brown fat in human health and could lead to new medications for treating obesity and type 2 diabetes.

Diet Studies: 2-Year Calorie Restriction Diets Lower LDL/Total Cholesterol, C-Reactive Protein & Blood Pressure

From The Lancet Diabetes & Endocrinology:

Calorie Restriction The Lancet Diabetes & Endocrinology Sept 20192 years of moderate calorie restriction significantly reduced multiple cardiometabolic risk factors in young, non-obese adults. These findings suggest the potential for a substantial advantage for cardiovascular health of practicing moderate calorie restriction in young and middle-aged healthy individuals, and they offer promise for pronounced long-term population health benefits.

Calorie restriction caused a persistent and significant reduction from baseline to 2 years of all measured conventional cardiometabolic risk factors, including change scores for LDL-cholesterol (p<0·0001), total cholesterol to HDL-cholesterol ratio (p<0·0001), and systolic (p<0·0011) and diastolic (p<0·0001) blood pressure. In addition, calorie restriction resulted in a significant improvement at 2 years in C-reactive protein (p=0·012), insulin sensitivity index (p<0·0001), and metabolic syndrome score (p<0·0001) relative to control. A sensitivity analysis revealed the responses to be robust after controlling for relative weight loss changes.

Obesity Studies: Visceral (Abdominal) Fat Is Major Risk Factor For Type 2 Diabetes, Atherosclerosis & Cardiovascular Disease

From The Lancet Diabetes & Endocrinology:

The Lancet Diabetes &amp; Endocrinology Sept 2019This joint position statement from the International Atherosclerosis Society and the International Chair on Cardiometabolic Risk Working Group on Visceral Obesity summarises the evidence for visceral adiposity and ectopic fat as emerging risk factors for type 2 diabetes, atherosclerosis, and cardiovascular disease, with a focus on practical recommendations for health professionals and future directions for research and clinical practice.

Findings from epidemiological studies over the past 30 years have shown that visceral adipose tissue, accurately measured by CT or MRI, is an independent risk marker of cardiovascular and metabolic morbidity and mortality. Emerging evidence also suggests that ectopic fat deposition, including hepatic and epicardial fat, might contribute to increased atherosclerosis and cardiometabolic risk.  We discuss the measurement of visceral and ectopic fat, pathophysiology and contribution to adverse health outcomes, response to treatment, and lessons from a public health programme targeting visceral and ectopic fat. We identify knowledge gaps and note the need to develop simple, clinically applicable tools to be able to monitor changes in visceral and ectopic fat over time. Finally, we recognise the need for public health messaging to focus on visceral and ectopic fat in addition to excess bodyweight to better combat the growing epidemic of obesity worldwide.

Health Studies: Short Sleep Duration And Sleep Disorders Have Adverse Effects On Heart Health

From a Circulation online release:

Average hours of nightly sleep…these results indicate that sleep may play an important role in health disparities and may represent a modifiable risk factor (along with diet and physical activity) for cardiometabolic risk in general and cardiometabolic health disparities specifically.

Statement Summary

Our review of the epidemiological data on the impact of sleep duration and disorders on cardiovascular health suggests the following:

  1. Both short- and long-duration sleep and sleep disorders such as SDB and insomnia are associated with adverse cardiometabolic risk profiles and outcomes.

  2. Sleep restriction has a negative impact on energy balance, but it is less clear whether treating sleep disorders has a positive impact on obesity risk.

  3. Treating those with sleep disorders may provide clinical benefits, particularly for blood pressure.

Sleep is increasingly recognized as an important lifestyle contributor to health. However, this has not always been the case, and an increasing number of Americans choose to curtail sleep in favor of other social, leisure, or work-related activities. This has resulted in a decline in average sleep duration over time. Sleep duration, mostly short sleep, and sleep disorders have emerged as being related to adverse cardiometabolic risk, including obesity, hypertension, type 2 diabetes mellitus, and cardiovascular disease.

Health Studies: Silent Or “Covert” Strokes Are Post-Surgery Risks, Increasing Risk Of Cognitive Decline

From a The Telegraph online article:

A new study (in The Lancet, Aug 16, 2019) reveals that pensioners who have an operation have a one in 14 chance of suffering a silent or “covert” stroke – an event that shows no obvious symptoms but can damage the brain.

The Lancet Covert Strokes Aug 16 2019

More than 1,100 patients across the world were given MRI scans nine days after some form of major non-cardiac surgery.

They were then followed up a year later to assess their cognitive abilities.

The researchers found that not only did having a silent stroke double the chances of cognitive decline a year on, it also increased the chances of a full life-threatening stroke.

Suffering a mini-stroke increased the risk of experiencing postoperative delirium as well.
