ONCOLOGISTS AND CARDIOLOGISTS HAVE LONG BATTLED THE DEVELOPMENT OF CARDIOMYOPATHY (WEAK HEART MUSCLE) DURING OR AFTER TREATMENT OF CANCER WITH CHEMOTHERAPY. (ESPECIALLY FOR BREAST CANCER) RECENTLY, 2 STUDIES USING ECHOCARDIOGRAMS (ULTRASOUND OF THE HEART), WERE ABLE TO DETECT AN ABNORMAL RELAXATION PATTERN OF THE HEART MUSCLE (DIASTOLIC DYSFUNCTION) PRIOR TO ANY SIGNIFICANT MUSCLE DAMAGE OR WEAKNESS OCCURS (SYSTOLIC DYSFUNCTION). THEY SHOWED THAT USING THE BLOOD PRESSURE MEDICATION ACE INHIBITORS AND CHOLESTEROL LOWERING STATIN MEDICATIONS THIS ABNORMAL RELAXATION PATTERN COULD BE LESSENED. FURTHER LARGE STUDIES WILL BE PERFORMED.
