Abstract

Previous studies have shown that long-term event-free survival after percutaneous balloon mitral valvuloplasty (PBMV) could be predicted by several baseline characteristics. However, the extent of the predictive variables has not been defined accurately yet. In this study, 40 baseline demographic, clinical, echocardiographic, and hemodynamic variables of 128 consecutive patients with mitral stenosis who underwent PBMV in a single institution, were analyzed in order to predict long-term event-free survival, defined as absence of death, mitral valve replacement, or repeat PBMV. Univariate survival analysis showed that age (p = 0.03), history of commissurotomy or mitral valvuloplasty (p = 0.05), calcium grade (p = 0.008), echo score (p = 0.0001), preprocedure cardiac output (p = 0.03), preprocedure valve area (p = 0.0007), postprocedure mean left atrial pressure (p = 0.0001), postprocedure valve area (p = 0.0001), postprocedure valve gradient (p = 0.013), and postprocedural mitral regurgitation (p = 0.01) were statistically significant predictors of event-free survival. Additionally, the absolute and/or relative procedural change of the following variables were found to be statistically significant predictors of event-free surviva...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
