How oxygen-producing pond scum could save your life after a heart attack – LA Times
The results, published Wednesday in the journal Science Advances, suggest a truly original approach to reducing the damage done to heart muscle when it is suddenly deprived of oxygen.
When blood flow to the heart is interrupted by a clot or the narrowing of vessels, the effect can be deadly, either now or later. It’s not uncommon for a heart attack victim to survive his or her immediate ordeal, only to succumb to heart failure — the effects of heart muscle weakened by its brush with oxygen deprivation — months or years after the event.
Physicians have long sought to avert that lingering damage by restoring the flow of oxygenated blood to the heart muscle as quickly as possible. Wielding an arsenal of drugs, stents, grasping devices, saws, scalpels and long, threaded catheters, cardiac surgeons try to isolate, remove or dissolve clots in the arteries feeding the heart before cells start to die off and lasting damage is done. More recently, stem cells have shown great promise in restoring damaged heart muscle.
