100 patients who have recently had an acute Myocardial Infarction ( heart attack) and are under going clinically indicated cardiac rehabilitation will undergo baseline testing including EndoPAT testing, mental stress testing, blood tests for cardiovascular disease biomarkers , physical assessments & survey questionnaires. Patients then will be randomized to either CalmioGO stress management device + standard of care treatment or just standard of care treatment. Those randomized to CalmiGO stress management device treatment will be instructed to use the hand device much like an inhaler once a day for 12 weeks. After 12 weeks of rehabilitation both groups will return for reassessment of baseline tests.
The primary purpose of this study is to determine if there are significant differences with respect to baseline between those randomized to CGo and standard-of-care versus standard-of-care alone after completing 12-weeks of therapy in terms of peripheral endothelial function measured by EndoPAT.
