Heart disease is the narrowing or blockage of the arteries and vessels that provide oxygen and nutrient-rich blood to the heart. It is caused by atherosclerosis, an accumulation of fatty materials on the inner linings of arteries that restricts blood flow. When the blood flow to the heart is completely cut off, the result is a heart attack because the heart is starved of oxygen.
Preventing a broken heart: Research aims to reduce scarring from heart attacks – A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity.
Back pain still an issue for over 5 million Australians: Are we treating it right? – A new study by researchers at The George Institute for International Health has found that back pain is a reoccurring problem for five million Australians.
New genes present drug targets for managing cholesterol and glucose levels – Scientists have identified 12 new genes that are somewhat strange bedfellows: Some link gallstones and blood cholesterol levels, others link melatonin and sleep patterns to small increases in glucose levels and larger jumps in the risk of diabetes.
High blood pressure in the doctor’s clinic may not predict heart risks. Round-the-clock blood pressure measurements, especially those during the night, are better predictors of major cardiovascular problems. – Continuously measuring blood pressure may help predict heart disease and related deaths among individuals with treatment-resistant hypertension, while blood pressure readings taken in a medical clinic do not appear to predict future heart risks, according to a report in November 24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Researchers have developed a list of 14 widely prescribed medications most urgently in need of additional study to determine how effective and safe they are for their off-label uses. – Physicians and policy-makers know that drugs are frequently prescribed to treat certain diseases despite a lack of FDA approval – a practice known as off-label prescribing. Yet they say the problem is so big they don’t know how to begin tackling it.
Centenarian offspring retain important cardiovascular advantages from their parents compared to a similarly-aged. – A recent study appearing in the November issue of Journal of American Geriatrics Society revealed that centenarian offspring (children of parents who lived to be at least 97 years old) retain important cardiovascular advantages from their parents compared to a similarly-aged cohort.
Ginkgo biloba does not reduce dementia or Alzheimer’s disease risk according to Pitt-led study in JAMA. – The medicinal herb Ginkgo biloba does not reduce the risk of dementia or Alzheimer’s disease development in either the healthy elderly or those with mild cognitive impairment, according to a large multicenter trial led by researchers at the University of Pittsburgh School of Medicine.
Vitamin C lowers levels of heart disease biomarker, finds study, adds to debate of health benefits – A new study led by researchers at the University of California, Berkeley, adds to the evidence that vitamin C supplements can lower concentrations of C-reactive protein (CRP), a central biomarker of inflammation that has been shown to be a powerful predictor of heart disease and diabetes.
Auckland participants wanted for polypill trial – A new clinical trial looking at a single pill to prevent cardiovascular disease is starting in Auckland, New Zealand.
Hannah Jones – a British Girl – won a legal case that allowed her to refuse a life-saving heart transplant surgery. – A British girl 13 years old, suffering from leukemia, Hannah Jones decided to refuse to have a heart transplant for her heart condition – a hole in her heart.
The researchers found that the cumulative incidence of ischemic stroke increased with increasing levels of nonfasting triglycerides. – Elevated nonfasting triglyceride levels, previously associated with an increased risk for heart attack, also appear to be associated with an increased risk for ischemic stroke.
Low risk for heart attack? Could an ultrasound hold the answer? Ultrasound helps predict heart attacks in “low risk” patients. – By adding the results of an imaging technique to the traditional risk factors for coronary heart disease, doctors at Baylor College of Medicine in Houston found they were able to improve prediction of heart attacks in people previously considered low risk.
