One of the main differences in the current study, says Prescott, is that unlike previous studies interventions were offered to all patients who met the selection criteria, not just those found to be distressed. "In further studies I'd like to see whether the beneficial effect depended on the patient's baseline psychological characteristics and whether everyone would derive benefit, or only those who have difficulty coping," says Prescott, adding that in a world of finite health care resources such research would help target the intervention to those who most need it.

But with investigators calculating a number needed to treat (NNT) analysis of nine patients to prevent one recurrent CVD event, Gohlke believes that the approach would prove remarkably cost effective. "My approximate calculation - with an NNT of nine - is that it would cost around ?éČ18,000 to prevent one event, making the approach at least as cost effective as most interventions," says Gohlke.

The actual mechanism behind the benefit delivered by CBT is open to debate. One possibility is that people who are less stressed are better able to take on board life style interventions such as giving up smoking, taking more physical activity and improving their diets. Additionally, stress is thought to exert detrimental effects on the cardiovascular system through activation of the catecholamine system. Catecholamines are known to raise heart rates. Indeed the SHIFT study presented at the ESC Congress in 2010 supported the concept that reduction of heart rate contributes significantly to the beneficial outcomes in patients with heart failure.
