Mitral Valve Prolapse, Psychoemotional Status, and Quality of Life: Prospective Investigation in the Current Era.

OBJECTIVE: The purpose of this study is to investigate whether mitral valve prolapse is associated with the patient's psychoemotional status and health-related quality of life.

METHODS: Mitral valve prolapse and mitral regurgitation were prospectively and comprehensively assessed in 281 patients (age 61 ± 13 years; 63% men); 216 patients with mitral valve prolapse were compared with 65 without mitral valve prolapse (of similar age and sex). Simultaneously, we assessed the patient's psychoemotional status (anxiety, depression, posttraumatic stress symptoms), health-related quality of life, and perceived severity of illness using validated questionnaires.

RESULTS: Twenty-nine percent of the patients had either no or mild mitral regurgitation (area of effective regurgitant orifice ≤0.2), and 71% had clinically significant mitral regurgitation (moderate/severe). Stratifying patients into no/mild vs moderate/severe mitral regurgitation revealed no differences in psychoemotional status or mental health-related quality of life between patients with mitral valve prolapse vs those without mitral valve prolapse within each subgroup; no/mild mitral regurgitation and moderate/severe mitral regurgitation (all P ≥ .5). In multivariate analysis, mitral valve prolapse was not independently associated with psychoemotional status or health-related quality of life (all P ≥ .4). In addition, while objective severity of the illness was not related to psychoemotional status or health-related quality of life (all P ≥ .2), the patient's perceived severity of illness predicted in and of itself all psychoemotional (all P < .03) and quality-of-life outcomes (all P < .003).

CONCLUSION: Mitral valve prolapse is not a determinant of the patient's psychoemotional status or quality of life. Psychoemotional status and health-related quality of life are determined by the patient's perception of the severity of the mitral valve disease, rather than by the presence of mitral valve prolapse.
