Cardiodynamics after Myocardial Infarction.
Professional Med J Jan ;11(1):22-6.

Various aspects of cardiodynamics have prognostic value after myocardial infarction (MI). These aspects were studied non-invasively by echocardiography, in one hundred MI patients. Fifty were having anterior wall MI and 50 were of Inferior wall MI. Thirty control subjects were also included. End diastolic volume (EDV), End systolic volume (ESV) and ejection fraction (EF%) were estimated by defining endocardial border and applying `cubed` formula. Results showed that in anterior wall MI group, EDV and ESV were highly significantly (P<0.001) increased (149.72 ± 37.36 and 81.14 + 22.25 respectively) as compared with the control group (108.70 ± 21.00 and 39.30 ± 4.30 respectively). EF% was highly significantly decreased (44.98 ± 6.41) as compared with the control group (64.70 ± 3.9). In Inferior wall MI group, EDV and ESV were highly significantly increased to 123.64 ± 17.19 and 57.66 + 9.58 respectively as compared with the control group; EF% was decreased highly significantly to 53.86 ± 5.99 as compared with the control group. EDV and ESV were increased and EF% was decreased to a greater extent in anterior wall MI group as compared with the inferior wall MI group. We conclude that anterior wall MI affects the cardiodynamics more adversely as compared with the inferior wall MI.
