Vulnerability to stress and cardiac outcomes

The BBC(British Broadcasting Corporation) “reports on a study”: measuring cardiovascular outcomes (blood pressure, levels of clot-forming platelets) against a patient’s vulnerability to stress. In the patients who were vulnerable to stress, apparently, their blood pressure took a lot longer to get back to normal after a stressful task than in the control group. More important, these patients had higher platelet levels. The platelet levels being high during stress is fine — after all, if the lion takes a chunk out of your arm, you want to stem the bleeding as quick as possible. The high platelet levels persisting afterwards is not fine, as they tend to form clots.
