Key result
Prior MI is linked to a ~23% lower RV peak filling rate versus normal subjects.
Why the study?
Ventricular filling and interactions between the right and left ventricles in patients with old myocardial infarction required evaluation.
Cross-Sectional (n=30)
No
Absolute Event Rate: 2.17% vs 2.82%
p-value: p=<0.01
Right ventricular filling is impaired in old myocardial infarction, occurring directly due to RV wall motion abnormalities in inferior MI, and indirectly due to impaired LV filling in anterior MI.
No takes yet. Share an insight, caveat, or question.
RV filling impairment in old MI may warrant monitoring; leaves open its independent prognostic value and need for longitudinal studies.
Bai et al. (1987) conducted a cross-sectional in Old myocardial infarction (n=30). Old myocardial infarction vs. Normal subjects was evaluated on Peak filling rate of the right ventricle (l/sec) (p=<0.01). Right ventricular peak filling rate was significantly reduced in patients with old anterior (2.17 l/sec) and inferior (2.18 l/sec) myocardial infarction compared to normal subjects (2.82 l/sec, p<0.01).
