Patients with clogged arteries tend to live longer when they receive coronary artery bypass surgery as compared to less-invasive percutaneous coronary intervention (PCI, or angioplasty and stenting ).

Previous studies have shown mixed results when it comes to debating whether coronary artery bypass surgery is safer "on pump" with the heart stopped or on a beating heart.

As healthcare has improved, it's no longer uncommon for patients to live past age 90. Guidelines do not currently address older heart attack patients receiving a stent to prop open a blocked artery.

Patients who receive coronary stents to prop open blocked arteries are at an added long-term risk of dying if they suffer from depression.

For patients with clogged arteries requiring coronary bypass surgery, the safest option may be an operation while the heart is stopped.

Older coronary artery disease patients receiving cardiac catheterization who remain chronically depressed appear to be at a significantly increased risk of suffering from cognitive decline.

In addition to the obvious companionship benefit that comes from marriage, married couples also appear to receive a boost in longevity after heart surgery.

Rheumatoid arthritis patients have a higher risk of heart-related problems, including hardened arteries. In order to protect the heart health of these patients, researchers must find what causes these heightened risks.

Not all stable patients with coronary artery disease will receive an added benefit from initial implantation of a stent to prop open a clogged artery.

Babies unable to grow to the size they're genetically supposed to reach suffer from intrauterine growth restriction, a risk factor for future cardiovascular problems.
