Among asymptomatic patients with very severe aortic stenosis, the incidence of the composite of operative mortality or death from cardiovascular causes during the follow-up period was significantly lower among those who underwent early aortic-valve replacement surgery than among those who received conservative care.
From a New Atlas online article (Jan 1, 2020):
“This is an entirely new approach with no current treatments able to change scar in this way,” says Associate Professor James Chong who led the research. “By improving cardiac function and scar formation following heart attack, treatment with rhPDGF-AB led to an overall increase in survival rate in our study.”
The research centers on a protein therapy called recombinant human platelet-derived growth factor-AB (rhPDGF-AB), which had previously been shown to improve heart function in mice that had suffered a heart attack. In a new study aimed at bringing the treatment closer to human trials, a team set out to discover if it produced similar results in large animals, namely pigs.
The researchers from the Westmead Institute for Medical Research (WIMR) and the University of Sydney found that when pigs that had suffered a heart attack received an infusion of rhPDGF, it did indeed prompt the formation of new blood vessels in the heart and led to a reduction of potentially fatal heart arrhythmia.
From a Harvard Medical School release:
Researchers matched 7,743 people with osteoarthritis with 23,229 healthy people who rarely or never took NSAIDs. People with osteoarthritis had a 42% higher risk of heart failure and a 17% higher risk of coronary artery disease compared with healthy people. After controlling for a range of factors that contribute to heart disease (including high body mass index, high blood pressure, and diabetes), they concluded that 41% of the increased risk of heart disease related to osteoarthritis was due to the use of NSAIDs.
To manage the painful joint disease known as osteoarthritis, people often take ibuprofen (Advil, Motrin) and naproxen (Aleve, Anaprox). But these and related drugs — known as NSAIDs — may account for the higher rates of heart disease seen in people with osteoarthritis, a new study suggests.

From a Stanford Medicine online release:
“For patients with severe but stable heart disease who don’t want to undergo these invasive procedures, these results are very reassuring,” said David Maron, MD, clinical professor of medicine and director of preventive cardiology at the Stanford School of Medicine, and co-chair of the trial, called ISCHEMIA, for International Study of Comparative Health Effectiveness with Medical and Invasive Approaches.
“The results don’t suggest they should undergo procedures in order to prevent cardiac events,” added Maron, who is also chief of the Stanford Prevention Research Center.
Patients with severe but stable heart disease who are treated with medications and lifestyle advice alone are no more at risk of a heart attack or death than those who undergo invasive surgical procedures, according to a large, federally-funded clinical trial led by researchers at the Stanford School of Medicine and New York University’s medical school.
The trial did show, however, that among patients with coronary artery disease who also had symptoms of angina — chest pain caused by restricted blood flow to the heart — treatment with invasive procedures, such as stents or bypass surgery, was more effective at relieving symptoms and improving quality of life.

From a Wall Street Journal online article:
The rapid aging of the population, together with high rates of obesity and diabetes in all ages, are pushing both the rate and number of deaths from heart failure higher, the study said. Most deaths from heart failure occur in older Americans, but they are rising in adults under 65, too, the study showed.
The findings help explain why a decadeslong decline in the death rate from cardiovascular disease has slowed substantially since 2011 and started rising in middle-aged people, helping drive down U.S. life expectancy.
Deaths from heart failure, one of the nation’s biggest killers, are surging as the population ages and the health of younger generations worsens.
The death rate from the chronic, debilitating condition rose 20.7% between 2011 and 2017 and is likely to keep climbing sharply, according to a study published Wednesday in the journal JAMA Cardiology.

From a Science Daily online release:
“People with heart failure cannot do everything that a healthy individual can, so the question becomes how much exercise can they handle and what type of impact will it have on their health,” Emter said. “We found that regardless of intensity level, some type of physical activity was good for heart health compared to no exercise at all.”
Now, research from the University of Missouri has found exercise can improve the health of blood vessels in the heart for people with heart failure. The finding is based on a study looking at swine, which have very similar blood vessels and heart muscles — both structurally and functionally — as humans.

“As a result, today’s epidemic of physical inactivity in conjunction with highly processed, high-sodium diets contributes to thicker, stiffer hearts that compromise the heart’s ability to cope with endurance physical activity, and importantly this may start to occur prior to increases in resting blood pressure,” explains Shave.
The landmark study analyzed 160 humans, 43 chimpanzees and five gorillas to gain an understanding of how the heart responds to different types of physical activity. In collaboration with Harvard University’s Daniel Lieberman and Aaron Baggish, UBC Professor Robert Shave and colleagues compared left ventricle structure and function in chimpanzees and a variety of people, including some who were sedentary but disease-free, highly active Native American subsistence farmers, resistance-trained football linemen and endurance-trained long-distance runners.

From an InterestingEngineering.com online article:
“We are extremely proud of what we have accomplished, from the ability to 3D bioprint human cardiac tissue last summer to a mini heart with full structure now. These milestones are a testament to the hard work of our team and the proprietary process we have developed that enables this type of scientific achievement,” said Birla in a press release. “We believe we are at the forefront of whole heart bioengineering, a field that has matured quickly over the last year, and well-positioned to continue our rapid scientific advancement.”
BIOLIFE4D, the biotech company based out of Chicago, announced it has successfully demonstrated the ability to 3D bioprint a mini human heart, a big step in someday printing out a full-sized human heart that can be used for a transplant.
From a ScienceDaily.com online release:
Physical 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.

From a Circulation online release:
…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.
Our review of the epidemiological data on the impact of sleep duration and disorders on cardiovascular health suggests the following:
Both short- and long-duration sleep and sleep disorders such as SDB and insomnia are associated with adverse cardiometabolic risk profiles and outcomes.
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.
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.
