Some "Good" Cholesterol May Be Bad For Heart
It appears that in some cases, high-density lipoprotein (HDL) cholesterol, the so-called "good" cholesterol, does not protect against heart disease, and may even be harmful. A new study suggests a subclass of HDL that carries a particular protein is bad for the heart. Previous studies have shown that high levels of HDL cholesterol are strongly linked to low risk of heart disease...

Rare DNA Variations May Be Responsible For Differences In Susceptibily To Heart, Lung And Other Disorders
One-letter switches in the DNA code occur much more frequently in human genomes than anticipated, but are often only found in one or a few individuals. The abundance of rare variations across the human genome is consistent with the population explosion of the past few thousand years, medical geneticists and evolutionary biologists report in the advanced online edition of Science...

For Chronic Kidney Disease Patients, One Type Of Open Heart Surgery Is Safer Than The Other
One type of open heart surgery is likely safer than the other for chronic kidney disease (CKD) patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Open heart, or coronary artery bypass, surgery can be done two ways: on-pump or off-pump, depending on whether the patient is put on a heart-lung machine...

Running Marathons - Death Risk Low, Higher Among Men
In recent years, the popularity of marathons has grown significantly and although the risk of dying during a marathon or soon after is extremely low - about 0.75 per 100,000 - men are two times more likely to die than women, say researchers at John Hopkins University School of Medicine. In addition, the number of individuals to complete grueling 26...

Improving Palliative Care For Heart Failure Patients
Palliative care for cancer patients in the UK is well established - but the situation is starkly different for those suffering from heart failure. A recent service evaluation led by the University of Hull and Hull York Medical School (HYMS) shows this doesn't have to be the case - particularly if clinicians have the courage to talk about death with their patients...

Controlling Blood Pressure - Team Based Care Vital
High blood pressure was listed as a primary or contributing cause of death for approximately 336,000 Americans in 2007. If all patients with high blood pressure were treated to goal as outlined in current clinical guidelines, it is estimated that 46,000 deaths might be averted each year...

Palpitations May Mean Looming Atrial Fibrillation
The European Journal of Preventive Cardiology reveals that the emergence of palpitations is a risk factor for atrial fibrillation (AF). Findings of a large population study reveal the strongest risk factors for atrial fibrillation in both men and women to be a history of palpitations and hypertension...

Common Antibiotic Found To Carry Heart Risk
Vanderbilt researchers have discovered a rare, but important risk posed by the antibiotic azithromycin, commonly called a "Z-pack." The study found a 2.5-fold higher risk of cardiovascular death in the first five days of taking azithromycin when compared with another common antibiotic or no antibiotics at all. Wayne A. Ray, Ph.D., professor of Preventive Medicine, and C. Michael Stein, M.B.Ch...

Large Population Study Fomds Palpitations Predictive Of Future Atrial Fibrillation
A large cohort study has found that the strongest risk factors for atrial fibrillation in both men and women were a history of palpitations and hypertension. While hypertension is a well known risk factor for AF, the investigators note that "the impact of self-reported palpitations on later occurrence of AF has not been documented earlier"...

Automated External Defibrillators Rarely Close To Locations Of Public Cardiac Arrests
More than 75 percent of cardiac arrest victims are stricken too far away from an automated external defibrillator for the lifesaving device to be obtained quickly enough to offer the best chance at saving their lives, according to new research from the Perelman School of Medicine at the University of Pennsylvania that was presented at the annual meeting of Society for Academic Emergency Medicine...

Faster Treatment For Heart Attack Patients Taken Directly To PCI Hospitals
Heart attack patients in North Carolina who were rushed directly to hospitals equipped to do percutaneous coronary intervention (PCI) received treatment significantly faster than patients first taken to hospitals unequipped to perform PCI and then later transferred for treatment, according to research reported at the American Heart Association's Quality of Care and Outcomes Res...

Predicting The Risk Of Sudden Cardiac Arrest Using Novel Imaging Could Better Identify Patients Who Would Benefit From ICDs
New research from the University at Buffalo suggests that cardiologists may have a new way to identify patients who are at the highest risk of sudden cardiac arrest, and the most likely to benefit from receiving an implantable cardiac defibrillator (ICD). ICDs are used to prevent sudden cardiac arrest in patients with advanced heart disease, but many patients' devices are never triggered...
