Acute Coronary Syndrome


The incidence of young athletes experiencing sudden cardiac arrest during competitive sporting events is slim—just 0.76 cases in 100,000 athlete-years—but it does happen, according to one team of Canadian researchers who analyzed dozens of out-of-hospital cardiac arrests in an effort to dissect the underlying causes of these tragedies.

A tool designed to predict the risk of MI and cardiac arrest (MICA) after noncardiac surgery in older patients works significantly better than two widely used models that aren’t age-specific, according to a study published Nov. 16 in the Journal of the American Heart Association.

Owning a dog could be linked to a decreased risk of cardiovascular disease (CVD) in single-person households and lower all-cause mortality in the general population, a 12-year study of Swedish canine owners suggests.

Elderly people with higher levels of the protein CXCL5 in their blood tend to have clearer arteries, researchers reported in the American Journal of Pathology.

Only 1 in 8 people who suffer a heart attack at age 50 or younger are on preventative statin therapy prior to their event, a new study reported. And what is even more concerning, according to researchers, is most of the untreated individuals weren’t eligible for statins based on guidelines.

Lipoprotein(a) not linked to increased CVD risk in ACS patients after all

Although the atherogenic lipoprotein(a) [Lp(a)] has been associated with incident cardiovascular disease, its concentration doesn’t predict the risk of ischemic cardiovascular events following acute coronary syndrome (ACS) in patients receiving other therapies, a study published in JAMA Cardiology reports.

Non-MI patients with elevated cardiac troponin remain at increased risk

Any detectable level of high-sensitivity cardiac troponin T (hs-cTnT) measured in an emergency department (ED) was associated with worse long-term survival—even when not accompanied by acute conditions known to impact troponin levels—according to a Swedish study published in the Journal of the American College of Cardiology.
