Heart Health“Virtual Human” Shows How Stiff Arteries Raise BP By Adprime Admin articleHigh blood pressure is highly age-related and affects more than 1 billion people worldwide. The condition is a major source of morbidity and mortality, because it makes individuals more prone to heart failure, stroke and kidney disease. Yet doctors can't fully explain the cause of 90 per cent of all cases. Now a computer model of a "virtual human", created by researchers at Norwegian University of Life Sciences, suggests that stiff arteries alone are enough to cause high blood pressure. The study was published in May 2014 in in PLOS Computational Biology.
_ Heart HealthHospital Visits for AFib Rising By articleHospitalizations and costs for treating irregular heartbeats, a condition called atrial fibrillation or AFib, are escalating. This fact is increasing the burden on the U.S. healthcare system, according to new research published in May 2014 in the American Heart Association journal Circulation. AFib can lead to stroke and other heart-related complications.
_ Heart HealthNew Heart Tx as Good as Gold Standard By articleLCZ696, a drug with two antihypertensives to lower blood pressure, won a head to head comparison with ACE inhibitors, the gold standard treatment.

Heart HealthViagra for Heart Failure? Works Better for the Guys By articleClear-cut gender differences stand out in measuring impact of Viagra as therapy for heart failure, according to a study done at Johns Hopkins and posted online May 16th 2014 in The Journal of Clinical Investigation. Specifically, in female mice modeling human heart failure, the benefits of sildenafil, the generic name for Viagra, ranged from robust to practically nonexistent depending on the animals' levels of the hormone estrogen. Yet in male mice, sildenafil generally appears to work well because it targets a different biological process independent of estrogen.
Heart HealthSugar Is Bad for Your Heart Even If You’re at a Healthy Weight By articleResearchers from New Zealand's University of Otago have uncovered evidence that sugar has a direct effect on risk factors for heart disease, and is likely to impact blood pressure, independent of weight gain. Dr Lisa Te Morenga, Research Fellow with Otago's Department of Human Nutrition, and colleagues conducted a review and meta-analysis of all international studies that compared the effects of higher versus lower added sugar consumption on blood pressure and lipids (blood fats or cholesterol) – both of which are important cardiovascular risk-factors.

_ Heart HealthDetermining The Benefits Of Aspirin By Jane Farrell articleScientists have developed a method for figuring out who should take aspirin to prevent heart attacks. Although the remedy has been recommended for more than 30 years, it’s been unclear exactly which individuals might benefit. New research published today in Circulation: Cardiovascular Quality and Outcomes shows that coronary artery calcium (CAC) score, a measurement of plaque in arteries that feed the heart, could help determine whether a person should take aspirin.
_ Heart HealthOriginal Oily Fish Study Flawed By articleYou’ve heard it here on ThirdAge and probably elsewhere as well: Oily fish such as salmon, fresh tuna, and swordfish are currently recommended as part of a heart healthy diet. Oops! An international team of researchers have called into question the validity of a now-classic study from the 1970s that claimed that because the diet of Eskimos in Greenland is rich in whale and seal blubber, these peopledon’t have coronary artery disease at the same rate as other populations.On the contrary, the Eskimos turn out to have alarmingly high rates of lethal CAD and stokes.
_ Heart HealthSix Tips to Turn Back the Clock on Your Heart By articleBy Steven Masley, MD, CNS The first step to avoiding cardiovascular disease, which is the #1 killer of Americans, including women—is understanding how your heart and arteries age.

_ Heart HealthEating Meat Ups Heart Disease Risk By articleHere’s more proof that steaks and burgers can be bad for your health: A new study from the Indiana University School of Public Health-Bloomington has bolstered the link between red meat consumption and heart disease by finding a strong association between heme iron, found only in meat, and potentially deadly coronary heart disease.
_ Heart HealthDeveloping A Safer NSAID By Jane Farrell articleResearchers are drawing closer to a safer alternative to non-steroidal anti-inflammatory drugs that relieve pain but can cause heart attacks, strokes and even sudden cardiac death. Investigators from the University of Pennsylvania built on previous work to further explore the role of an enzyme, mPGES-1, in delaying the development of atherosclerosis. Their findings were reported in the Proceedings of the National Academy of Sciences.
Heart HealthPredicting Heart Disease in Low-Risk Patients By articleWith growing evidence that a measurement of the buildup of calcium in coronary arteries can predict heart disease risk, Los Angeles Biomedical Research Institute (LA BioMed) researchers found that the process of "calcium scoring" was also accurate in predicting the chances of dying of heart disease among adults with little or no known risk of heart disease. Matthew J. Budoff, MD and Rine Nakanishi, MD, PhD presented the in March 2014 findings at Acc.14, the annual scientific session of the American College of Cardiology, in Washington D.C
