Red blood cells exposed to oxygen deficiency protect against myocardial infarction (heart attack), according to a new study, adding that the protective effect is enhanced by a nitrate-rich vegetable diet.

Red blood cells carry oxygen from the lungs to all of the body’s cells and carbon dioxide back to the lungs.

A new study, conducted at Karolinska Institutet in Sweden in collaboration with Karolinska University Hospital, now shows that red blood cells have an intrinsic function of protecting against heart injury caused by myocardial infarction.

The effect is enhanced by a diet containing nitrate-rich vegetables, such as arugula and other green leafy vegetables.

“This effect was also shown in a clinical study in patients with high blood pressure who were randomly assigned to eat nitrate-rich vegetables or a diet low in nitrates,” said John Pernow, professor of cardiology at the department of medicine, Karolinska Institutet.

Part of the study was conducted through experiments with red blood cells from mice that were added to a myocardial infarction model with hearts from mice.

Before the experiment, the red blood cells were exposed to low oxygen pressure, while nitrate was added to the drinking water.

In a clinical study published in the Journal of Clinical Investigation, red blood cells were collected from patients with high blood pressure who were

randomly assigned a nitrate-rich diet with green leafy vegetables or a diet with nitrate-poor vegetables.

These red blood cells were given to the corresponding myocardial infarction model with hearts from rats.

“The results show both that the red blood cells convey protection against injury in the heart in the event of low oxygen levels, and how that protection can be enhanced through simple dietary advice. This may be of great importance for patients at risk of myocardial infarction,” said Jiangning Yang, a researcher at Karolinska Institutet.
