Background
In patients with mitral stenosis (MS), Doppler pressure half-time (PHT) may be influenced by hemodynamic variables other than the anatomic mitral valve orifice narrowing. This study was undertaken to assess whether the presence of concomitant mitral regurgitation (MR) affects mitral valve area (MVA) estimation by PHT.Methods
Consecutive patients (n = 166) with noncalcific MS, in sinus rhythm, were studied. Group 1 (n = 106) had no or mild MR, and group 2 (n = 60) had moderate or severe MR. MVA was assessed by using the PHT method and planimetry.Results
There was a strong correlation between planimetry and PHT MVA in both groups (group 1: r = 0.86, P < .001; group 2: r = 0.73, P < .001). However, compared with planimetry MVA, PHT underestimated MVA by ≥20% in 18 patients (17%) in group 1 and 21 patients (35%) in group 2 (P < .01). Overestimation by ≥20% occurred in 12 patients (11%) in group 1 and in 7 (12%) in group 2. Group 2 subanalysis (group 2A: moderate MR, n = 16; group 2B: severe MR, n = 44) revealed that linear regression weakened with increasing severity of MR (group 2A: r = 0.824, P < .001, group 2B: r = 0.70, P < .001). PHT underestimation of MVA occurred in 31% and 36% of patients in Groups IIA and IIB, respectively (P = NS).Conclusions
PHT appears to be reliable for estimating MVA in most patients with MS, even in the presence of MR. However, the presence of significant MR reduces the reliability of PHT-derived MVA, with underestimation of MVA in a significant number of subjects. The severity of MR has a direct impact on PHT-derived MVA. 相似文献6.

Unilateral pulmonary edema is a distinctly unusual clinical entity that presents interesting and confusing diagnostic challenges. It is usually described as occurring with re-expansion of a collapsed lung after rapid thoracocentesis of pleural air or pleural fluid. Unilateral pulmonary edema as an initial presenting manifestation for heart failure is uncommon and can be confused with other more common causes of alveolar or interstitial infiltrate, which can lead to a significant delay in treatment. 相似文献

Receptor for advanced glycation endproducts (RAGE) is a cell-surface molecule member of the immunoglobulin superfamily and engages differing ligands relevant to distinct processes. A growing body of evidence has suggested that RAGE may promote vascular inflammation through several mechanisms. The objective of this study was to identify the possible relationship between the -374 T/A polymorphism of the RAGE gene, myocardial infarction (MI), and its age of onset. A total of 691 MI patients and 234 matched controls were investigated. In this study, the frequency of the A allele and AA genotype of the -374 T/A promoter polymorphism is significantly lower in patients with MI respect to the control group (p?0.01). Our results showed a significant role of the AA genotype on age of onset of MI. In particular, the mean age of the first MI was higher in patients with the AA genotype as compared to those that were AT or TT genotype carriers (p?=?0.002). The relationship between -374 T/A RAGE polymorphism and age for the appearance of MI was independently related to common risk factors of disease (p?0.01). Kaplan-Meier curves confirmed that subjects with the AA genotype have a later development of MI (p?=?0.0022). This study is the first to investigate the role of RAGE polymorphisms on the susceptibility to develop the acute coronary events in the Italian population and identified this polymorphism as an age-related factor for MI development. The homozygous AA genotype may exert a protective role against the early development of MI. 相似文献
