Figure 1.

(A) Right ventricular fractional area change, expressed as a percentage, is significantly higher in individuals with no pulmonary hypertension (no PHTN), as demonstrated by the black columns, than in patients with chronic pulmonary hypertension (PHTN), as seen in the grey columns. (B) A significantly lower Eccentricity Index, as expected, is noted in individuals with no pulmonary hypertension when compared to patients with chronic pulmonary hypertension. (C) Similarly, a lower right ventricular Myocardial Performance Index is noted among normal individuals when compared to patients with chronic pulmonary hypertension.
