MATRINA DORSEY MAY BE 32 YEARS YOUNGER THAN JUDY BORGULA BUT THEY'RE BOTH WORRIED ABOUT THEIR HEARTS. JUDY SURVIVED AN EPISODE OF CARDIAC ARREST SEVERAL MONTHS AGO. I NEEDED TO KNOW MORE ABOUT WHAT IT'S GOING TO TAKE TO KEEP MY HEART HEALTHY.  MATRINA HAS TROUBLESOME HEART PALPITATIONS. YOU HEAR ABOUT YOUNGER PEOPLE HAVING HEART ATTACKS AND STROKES AND I JUST WANT TO KNOW MORE ABOUT IT AND TRY TO PREVENT IT.  MATRINA AND JUDY GOT SOME ANSWERS AT HEART SCHOOL.  RESEARCH SHOWS, 30 MINUTES OF EXERCISE MOST DAYS OF THE WEEK WILL PROVIDE YOU HEALTH BENEFITS. FROM EXERCISE...TO DIET...TO RISK FACTORS, THE THREE HOUR COURSE AT SAINT JOSEPH'S HOSPITAL IN ATLANTA TEACHES STUDENTS WHAT THEY CAN DO TO KEEP THEIR HEARTS HEALTHY. THESE AREN'T PERMANENT FIXES TO ANYTHING. THESE ARE ABOUT LEARNING NEW LIFESTYLES, DIETARY CHOICES, PHYSICAL ACTIVITY CHOICES. FOR SOME CARDIAC PATIENTS, HEART SCHOOL IS OFTEN ONE OF THE FIRST STEPS TOWARD RECOVERY. WHEN YOU'RE IN THE HOSPITAL IT'S VERY STRESSFUL, WHEREAS THIS IS SOMETHING THAT YOU CAN THINK ABOUT AND PLAN. AND HOPEFULLY CONTINUE THE HEART HEALTHY LESSONS AT HOME
