Idiopathic mitral valve prolapse was associated with a significantly higher ponderal index (13.1) compared to normal findings (12.3, P<0.001), indicating an asthenic habitus.
Observational (n=146)
Does somatotype (ponderal index) differ in patients with idiopathic mitral valve prolapse compared to those with normal findings or exaggerated systolic bulging?
Patients with idiopathic mitral valve prolapse exhibit a more asthenic habitus (higher ponderal index) independent of thoracic skeletal abnormalities.
Absolute Event Rate: 13.1% vs 12.3%
p-value: p=<0.001
Records from 18 subjects with angiographic idiopathic mitral valve prolapse, 28 subjects with merely exaggerated posterior mitral leaflet systolic bulging, and 100 subjects with normal hemodynamic and angiographic findings were compared with regard to age, sex, height, weight, ponderal index (height/3 square root weight), auscultatory and echocardiographic abnormalities. Chest x-ray films available for subjects with mitral valve prolapse were reviewed. The ponderal index of subjects with mitral valve prolapse (13.1 +/- 0.8) differed from that of subjects with merely exaggerated posterior mitral leaflet systolic bulging (12.6 +/- 0.7) (P less than 0.02) and from that of subjects without angiographic abnormality (12.3 +/- 0.8) (P less than 0.001). The three groups differed in ponderal index when equated statistically for age, height, weight, and sex (P less than 0.001). Among mitral valve prolapse patients, an asthenic habitus occurred independent of the presence of thoracic skeletal abnormalities.
Zema et al. (Fri,) conducted a observational in Idiopathic mitral valve prolapse (n=146). Idiopathic mitral valve prolapse vs. Normal hemodynamic and angiographic findings was evaluated on Ponderal index (height/cube root of weight) (p=<0.001). Idiopathic mitral valve prolapse was associated with a significantly higher ponderal index (13.1) compared to normal findings (12.3, P<0.001), indicating an asthenic habitus.
