The Influence of Sex on Clinical Outcomes after Surgical Mitral Valve Replacement in Spain (2001-2015).

ABSTRACT: (1) Background: Mitral regurgitation (MR) is the second most prevalent valvular heart disease in developed countries. Mitral valve (MV) disease is a common cause of heart failure and a leading cause of morbidity and mortality in the U.S.A. and Europe. (2) Methods: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2001-2015. We included patients that had surgical mitral valve replacement (SMVR) listed as a procedure in their discharge report. We sought to (i) examine trends in incidence of SMVR among women and men in Spain, (ii) compare in-hospital outcomes for mechanical and bioprosthetic SMVR by sex, and (iii) identify factors associated with in-hospital mortality (IHM) after SMVR. (3) Results: We identified 44,340 hospitalizations for SMVR (84% mechanical, 16% bioprosthetic). The incidence of SMVR was higher in women (IRR 1.51; 95% CI 1.48-1.54). The use of mechanical SMVR decreased over time in both sexes and the use of bioprosthetic valves increased over time in both sexes. Men who underwent mechanical and bioprosthetic SMVR had higher comorbidity than women. IHM was significantly lower in women who underwent SMVR than in men (10% vs. 12% p < 0.001 for mechanical and 14% vs. 16% p = 0.025 for bioprosthetic valve, respectively). Major adverse cardiovascular and cerebrovascular events (MACCE) were also significantly lower in women who underwent mechanical and bioprosthetic SMVR. A significant reduction in both in-hospital MACCEs and IHM was observed over the study period regardless of sex. After multivariable logistic regression, male sex was associated with increased IHM only in bioprosthetic SMVR (OR 1.28; 95% CI 1.1-1.5). (4) Conclusions: This nationwide analysis over 15 years of sex-specific outcomes after SMVR showed that incidences are significantly higher in women than men for mechanical and bioprosthetic SMVR. IHM and MACCE have improved over time for SMVR in both sexes. Male sex was independently associated with higher mortality after bioprosthetic SMVR.

Project description:BackgroundThe main aims of this study were to examine the incidence and in-hospital outcomes of mechanical and bioprosthetic surgical mitral valve replacement (SMVR) among patients with and without T2DM.MethodsWe performed a retrospective study using the Spanish National Hospital Discharge Database from 2001 to 2015. We included patients with SMVR codified in their discharge report. We grouped admissions by diabetes status. Propensity score matching (PSM) was used to compare outcomes of isolated SMVR.ResultsWe identified 42,937 patients (16.41% with T2DM). Incidence rates of mechanical and bioprosthetic SMVR were higher among T2DM patients than among non-T2DM patients. In both groups of patients, the use of bioprosthetic SMVR increased over time. The use of mechanical valves remained stable among T2DM patients. In T2DM and non-T2DM patients with mechanical SMVR, in hospital mortality (IHM) and MACCE decreased significantly (p < 0.001) from 2001 to 2015. T2DM patients had an overall 11.37% IHM, compared with 10.76% among non-T2DM patients (p = 0.176). Regarding MACCE figures were 14.72% vs. 14.22% (p = 0.320) after mechanical SMVR. Total crude IHM were 14.29% for T2DM patients and 15.13% for those without T2DM with bioprosthetic SMVR (p = 0.165) and 18.22 vs. 19.64%, for a MACCE (p = 0.185). Using PSM we found that the IHM and the MACCE of isolated SMVR did not differ significantly between patients with or without T2DM beside the type of valve replacement. Among T2DM patients, those who received bioprosthetic valves had higher IHM (14.29% vs. 11.37%; p = 0.003) and a higher rate of MACCE (18.22% vs. 14.72%; p = 0.001) than T2DM patients with mechanical SMVR.ConclusionsIn Spain from 2001 to 2015, the incidence rates of hospitalization to undergo mechanical or bioprosthetic SMVR were higher among the population suffering T2DM than among the non-T2DM population. In both groups of patients the use of bioprosthetic SMVR increased over time and the use of mechanical valves remained stable in T2DM. T2DM patients have IHM and MACCE after mechanical and bioprosthetic SMVR which are not significantly different to those found among non-diabetic patients. Among T2DM patients, the crude IHM was significantly higher in those who received a bioprosthetic SMVR than those with mechanical SMVR.
