my husband had a heart attack in March. Had an angioplasty/+2 stents and all of the usual meds. Since the attack, he has muscular pain in his chest/and arms. Has been tested...no enzymes...stopped statins after just 2 weeks of use. Had another nuclear stress test...ok. Any ideas? He is 50, not overweight, no high cholesterol, no high bp, is a diet controlled diabetes.
