Table 5 Association between baseline mitral regurgitation and presence of pulmonary hypertension (PHTN) (defined as pulmonary systolic pressure 36 mm Hg or higher)

From: Valvular regurgitation and surgery associated with fenfluramine use: an analysis of 5743 individuals

  Mitral regurgitation at baseline
  None Trace Mild Moderate Severe
Total 1804 3011 624 253 51
PHTN present (n) 12 59 36 32 11
PHTN absent (n) 1792 2952 588 221 40
PHTN (%) 0.67 1.96 5.77 12.65 21.57
OR for PHTN 1 2.7 (1.4–5.0) 7.6 (3.9–15) 15 (7.4–30) 28 (12–69)
  1. Odds ratio (OR) for PHTN was derived by multiple logistic regression with (95% CI), adjusting for age and gender. Shown are both numbers (n) and percent (%) with PHTN.
