Which has the stronger impact on coronary artery disease, eicosapentaenoic acid or docosahexaenoic acid?

It has been suggested that n-3 polyunsaturated fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), protect against cardiovascular diseases, and EPA/arachidonic acid (AA) and DHA/AA ratios in serum are potential risk markers for coronary artery disease (CAD). The purpose of this study was to clarify the clinical significance of the difference in the EPA/AA ratio and the DHA/AA ratio in patients with CAD. In 369 patients with confirmed or suspected CAD who underwent diagnostic coronary angiography, we measured serum levels of EPA, DHA and AA and calculated the EPA/AA and DHA/AA ratios.

Effect of a cardiac rehabilitation program on exercise oscillatory ventilation in Japanese patients with heart failure.

Although exercise oscillatory ventilation has emerged as a potent independent risk factor for adverse prognosis in heart failure, it is not well known whether cardiac rehabilitation can improve oscillatory ventilation. In this study, we investigated the magnitude of oscillations in ventilation before and after cardiac rehabilitation in chronic heart failure patients with exercise oscillatory ventilation. Cardiac rehabilitation (5-month program) was performed in 26 patients with chronic heart failure who showed an oscillatory ventilation pattern during cardiopulmonary exercise testing (CPX).
