Mitral valve prolapse and cerebrovascular accidents in the young
Insights
Mitral valve prolapse (MVP) is a significant risk factor for stroke in young adults in India. This study found MVP in 13% of young stroke patients, highlighting its importance in stroke risk assessment.
Area of Science:
- Cardiology
- Neurology
- Public Health
Background:
- Stroke incidence is notably high among young individuals in India.
- The specific contribution of mitral valve prolapse (MVP) syndrome to stroke in this demographic remains unclear.
Purpose of the Study:
- To prospectively evaluate the role of mitral valve prolapse (MVP) as a risk factor in patients under 40 years of age experiencing stroke.
Main Methods:
- A 1-year prospective study was conducted on young stroke patients.
- Diagnosis of MVP was confirmed using M-mode echocardiography.
- Standard stroke risk factors were assessed in all participants.
Main Results:
- Out of 38 young stroke cases, 17 had identifiable risk factors.
- Mitral valve prolapse (MVP) was detected in 13% of all young stroke patients.
- MVP prevalence increased to 23.8% in cases without other identified risk factors.
Conclusions:
- Mitral valve prolapse (MVP) is a significant risk factor for stroke in young adults.
- Investigation for MVP is warranted in young patients presenting with stroke, particularly when other risk factors are absent.
Abstract:
The incidence of stroke in the young is reported to be high in India. The role of the mitral valve prolapse (MVP) syndrome in these patients is not clear. A prospective study over a period of 1 year was carried out in order to evaluate the role of MVP in cases of stroke occurring in patients below the age of 40 years. Of the 38 cases of stroke in the young seen during this period, well-recognised risk factors of stroke could be detected in 17. MVP confirmed by M-mode echocardiography was seen in 13% of all stroke patients and in 23.8% of those in which there were no other risk factors. The incidence of MVP was much higher if only the clinical criteria for diagnosis were used. We believe that MVP is a significant risk factor in younger stroke patients, and, in such cases, merits investigation. The probable pathogenic mechanisms and therapeutic implications are discussed.
