A team of scientists from Massey University in New Zealand has found that overactivity in the gene responsible for encoding a protein to form new blood vessels hinders human recovery after a heart attack.
The study, published in the journal Plos One and based on the medical histories of 1,927 people, 30% of whom had more than one heart attack, concluded that these cases were linked to the VEGF-A gene.
Scientists hypothesized that high levels of activity of the mentioned gene is beneficial for the growth of new blood vessels near blocked arteries.
But the study showed that an elevated level of the VEGF-A gene may indicate the body is trying to restore heart function, a process that is unsuccessful in some severe cases.
The study concluded that patients with high VEGF-A levels are over 40% more likely to die within the first eight years after being hospitalized for the first time than patients with low VEGF-A levels. .
