Katharine Hepburn had her annual cardio checkup today and all is well. Grade 1 heart murmur as usual-which we all know doesn't mean a thing. Size of murmur doesn't indicate heart disease nor indicates a lack of heart disease. A louder murmur doesn't mean a more severe heart condition and a low murmur does not mean a lack of a heart disease. Katharine gets an annual checkup because she has a murmur (and all murmurs should be checked with an echo because (again) size of sound does not matter but the presence of a murmur may indicate heart disease) AND because she is Myrna Loy's sibling.
