Heart Health

Just as an engine makes a car go, your heart keeps your body running. Heart disease is a wide-reaching term to describe a range of conditions that affect the heart. The term “heart disease” is often used interchangeably with “cardiovascular disease” and generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain, or heart failure. Other heart conditions, such as infections and conditions that affect your heart’s muscle, valves or beating rhythm, are also considered forms of heart disease. There are dozens of cardiovascular diseases—the following are the most common:

Patients, Have a Statin Discussion with Your Doctor

Posted by Jane Farrell

Patients and physicians should work together to decide on individualized treatments based on new statin guidelines, according to a commentary by three Mayo Clinic doctors. The guidelines, issued last year by the American College of Cardiology and the American Heart Association, called for caregivers to prescribe statins to healthy patients if their 10-year cardiovascular risk is 7.5 percent or higher.

When Good Cholesterol Goes Bad

Posted by

A dysfunctional version of the normally protective protein that makes high-density lipoprotein (HDL) – the so-called "good cholesterol" –promotes inflammation and coronary artery disease. That’s the finding of researchers at the Cleveland Clinic who discovered the process by which HDL loses its cardio-protective properties, and instead causes atherosclerosis, or the clogging and hardening of the arteries. Their research was published online January 26th 2014  in the journal Nature Medicine.

Hope for New Meds for Heart Arrhythmia

Posted by

A common mechanism of cardiac arrhythmias, or irregular heartbeats, is calcium overload in the heart. However, the underlying mechanism has remained a mystery for decades. Now findings published in the January 19th 2014 edition of the journal Nature Medicine report the discovery of a physiological process that causes the calcium-triggered arrhythmias. The researchers at the Libin Cardiovascular Institute of Alberta in Canada hope their work will one day help design molecularly tailored medications that correct the pathophysiology.

Surprise! Dense Heart Plaques Are Better, Not Worse

Posted by

A surprise finding of study led by researchers at the University of California-San Diego School of Medicine shows that that coronary artery calcium (CAC) density may be protective against cardiovascular events rather than raising the risk of disease as has long been assumed. A release from the university quotes lead author Michael H. Criqui, MD, MPH as saying, "Current scoring systems assume that denser heart plaque (CAC) is more hazardous, but we found the opposite.

A Patch for Tracking Heart Rhythms

Posted by

Research done at the Scripps Translational Science Institute in San Diego has found that a small adhesive wireless device worn on the chest for up to two weeks does a better job detecting abnormal and potentially dangerous heart rhythms than the Holter monitor that has been the standard of care for more than 50 years.
