I am a 62 year old female who had just one bout with A Fib 6 weeks ago. My heart was beating really fast so I went to the ER where they saw the A Fib on and EKG. They did a chest X-ray which showed no lung problems and heart silhouette and pulmonary vascularity were fine. My blood tests were all normal except for a very small amount of troponin which increased in small increments after 3 tests. They were afraid of a mild heart attack so an echo and a heart cath were performed. No heart attack! No significant blockages were shown on the cath (one at 40% and one at 50% both in LAD). All other arteries were pretty much disease free (two irregularities but no disease ). The echo was ok (I guess) but it said I had grade 2 diastolic dysfunction. There was also mild pulmonary hypertension, mild tricuspid regurgitation, mild mitral annular calcification, mild thickening/calcification of the anterior and posterior mitral leaflets, LV EF 60 hyperdynamic. Ventricular cavity size was normal. Ventricular LVPW as well and IVS wall thicknesses were normal and evidence of a sigmoid septum. No LVOT obstruction. LV fractional change area was normal. Wall scoring: All segments are normal. Right ventricle was normal; RV thickness normal; global RV systolic function is normal. Aortic valve with no regurgitation and no degree of aortic stenosis is present. Aorta within normal limits. No pericardial effusion is seen. No pleural effusion if left or right lateral area. Left and right atrial sizes normal. IWAS IN A FIB WHEN ECHO WAS PERFORMED. HOW MUCH OF A ROLE DID THE A FIB PLAY IN THE OUTCOME OF THE ECHO? I HAD RETURNED normal sinus rhythm for the heart cath. My question is how bad is this diastolic dysfunction? Could it be attributed to the A Fib? Is my heart structurally normal? Cardiologist said it was a possibility that the DD was a false positive...will do another echo in 6 months . I am scared to death as this leads to CHF.
