Increased physical activity reduces coronary heart disease and cardiac mortality rates by 30-40% compared to inactive individuals. Exercise training also improves endothelial function, reducing atherosclerosis and plaque formation, and can even extend life expectancy in patients with stable coronary artery disease.
A study led by Dr. Michelle Graham highlights the need for higher rates of cardiac catheterization testing in Alberta and Canada. The research shows that many patients with high-risk blockages remain undetected, emphasizing the importance of increasing angiogram prescriptions to save lives.
Patients with rheumatoid arthritis (RA) are at a higher risk of developing coronary artery disease (CAD), with more advanced atherosclerosis and increased cardiovascular death. The underlying RA disease process, particularly elevated CD4+CD28- T cells, contributes to this increased risk.

A study by the American Heart Association found that individuals with heart attacks are more likely to have periodontal disease, a type of gum tissue inflammation. The researchers believe that high blood levels of C-reactive protein may be linked between the two conditions.
Researchers found that children with a parent who had a premature heart attack showed structural and functional abnormalities in their arteries as young as 6 years old. These changes included thickened vessel walls and decreased reactivity, which can lead to atherosclerosis and increase the risk of heart disease.
The NHLBI has launched a 10-year study to find new ways of detecting heart disease early, before symptoms appear. The $68 million Multi-Ethnic Study of Atherosclerosis (MESA) will collect data on various risk factors, including calcium deposits in coronary arteries and pulse waves at the radial artery.

Additionally, quitting at an older age can still lead to improved life expectancy and a lower risk of smoking-induced mortality.
A study found that young women with heart disease experience worsening exercise performance and angina pain in the early follicular phase, just after menstruation, but improved performance and slower pain onset in mid-cycle. Sex hormones may play a role in these fluctuations.
