Diagnosis of ischemic right ventricular dysfunction by M-mode echocardiography
Why the study?
Does M-mode echocardiography accurately diagnose ischemic right ventricular dysfunction in patients with acute myocardial infarction?
Population
63 patients with acute myocardial infarction (35 with ischemic right ventricular dysfunction, 28 without)
Comparison
M-mode echocardiography vs Hemodynamic criteria
Design
Cross-sectional

Implication
May aid ruling in ischemic RV dysfunction in AMI due to high specificity; leaves open prospective validation before clinical adoption.
Structured PICO
Does M-mode echocardiography accurately diagnose ischemic right ventricular dysfunction in patients with acute myocardial infarction?
P
Population
63 patients with acute myocardial infarction (35 with ischemic right ventricular dysfunction, 28 without)
I
Intervention
M-mode echocardiography (evaluation of right ventricular diastolic dimension and right ventricular/left ventricular diastolic dimension ratio)
C
Comparator
Hemodynamic criteria (right atrial pressure > 10 mm Hg and greater than, equal to or not more than 5 mm Hg less than pulmonary capillary pressure)
O
Outcome
Diagnostic accuracy (sensitivity and specificity) of M-mode echocardiographic indices for ischemic right ventricular dysfunctionsurrogate
M-mode echocardiographic indices of right ventricular dilatation have high specificity but low sensitivity for diagnosing ischemic right ventricular dysfunction in acute myocardial infarction.
