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.

Exercise can’t prevent cognitive decline in patients with coronary heart disease

Patients with stable coronary heart disease (CHD)—despite being considered “fit” and participating in phase III cardiac rehabilitation—demonstrated worse cognitive function when compared to healthy, age-matched individuals in a single-center study published in PLOS One.

Cardiac adrenaline boost from e-cigarettes tied to nicotine

Nicotine in electronic cigarettes boosts the cardiac adrenaline levels of users, which could put them at increased risk for heart disease, according to a new study in the Journal of the American Heart Association.

Adherence to medications post-MI is below 50%; beta-blockers offer little incremental benefit

Based on clinical guidelines, three therapies are often prescribed together following acute MI: angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARBs), beta-blockers and statins. But are they equally important?

Researchers confirm link between retinal vein occlusion, heart attack

In a large, retrospective study of the Taiwan population, researchers found individuals with retinal vein occlusion (RVO) demonstrated an adjusted risk increase of 21 percent for suffering a heart attack.

Ticagrelor shows long-term benefit in those with previous MI

Patients who have suffered a previous heart attack remain at increased risk for another myocardial infarction (MI), cardiovascular death or stroke, with no indication of the risk level waning over time. According to new research, the optimal dose of ticagrelor shows consistent benefits in reducing ischemic risk over five-plus years in heart attack patients, while its added risk for major bleeding events abates over time.

CDC: 2 of 3 heart attack patients spurn rehab

Despite proven survival benefits, roughly two-thirds of heart attack patients forego cardiac rehabilitation, according to a report from the Centers for Disease Control and Prevention (CDC).

Does public awareness of CPR, AEDs reduce response time to cardiac arrest?

National organizations, state governments and local communities have attempted to battle out-of-hospital cardiac arrest (OHCA) by supporting public awareness and improving preparedness, most notably through CPR training and use of automated external defibrillators (AEDs). A recent study—published online July 31 in Resuscitation, the journal of the European Resuscitation Council—examined the effectiveness of the Minnesota Heart Safe Communities program.

Study confirms effectiveness of new-generation heart stents in women

New-generation drug-eluting stents (DES) demonstrate long-term safety in women with acute myocardial ischemia (MI), with increased benefits for more severe cases of acute coronary syndrome (ACS), according to a new study.

Local gene therapy improves myocardial blood flow in refractory angina patients

For the first time, researchers have employed local gene therapy to boost myocardial blood flow in areas that have impaired perfusion reserves. They have also determined that elevated plasma Lp(a) can serve as a biomarker to identify those individuals with refractory angina (RA) who can benefit from the experimental therapy, gene transfer of VEGF-DΔNΔC.

Adults with acute coronary syndrome in registry differ from those in clinical trial

A registry analysis found that approximately one-third of patients who currently have acute coronary syndrome would have qualified for the IMPROVE-IT trial, which enrolled patients between 2005 and 2010.
