Given the potential detrimental effect of elevated expiratory positive airway pressure (EPAP) on cardiac output, we hypothesized that relatively lower EPAP may be recommended for successful ASV therapy. In-hospital patients with congestive heart failure refractory to medical therapy were included in the prospective cohort study of ASV therapy on prognosis in repeatedly hospitalized patients with chronic heart failure: longitudinal observational study of effects on readmission and mortality (SAVIOR-L) study. Assignment to either the ASV treatment group or the medical management group was at the discretion of the attending physicians. For the purposes of this retrospective study, our focus remained solely on the ASV cohort. We conducted an extensive analysis to elucidate the influence of lower EPAP settings on midterm mortality. A total of 108 patients were included. The median age was 74 years, and 83 (77%) patients were male. The median EPAP setting employed was 4 cmH₂O, with 60 patients subjected to EPAP levels below 5 cmH₂O. There were no significant differences in the baseline characteristics between the lower and higher EPAP groups, which were divided at the EPAP cutoff of 4.5 cmH₂O (p > 0.05 for all). A trend toward reduced mortality emerged among patients with EPAP settings below 5 cmH₂O, exhibiting a hazard ratio of 0.48 (95% confidence interval 0.22-1.07, p = 0.072) after adjusting for potential confounding factors: 2-year mortality 26% vs. 38%; p = 0.095. Heart failure readmission rates were not significantly different between the two groups (p = 0.61). The adoption of relatively lower EPAP settings during ASV therapy may be advisable. Such an approach has the potential to ameliorate mortality rates while concurrently maintaining heart failure recurrence rates at levels commensurate with those with default EPAP settings.</p>","PeriodicalId":12940,"journal":{"name":"Heart and Vessels","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142285873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the predictors of atrial tachyarrhythmia (ATA) recurrence and compares outcomes between HPSD-PVI and conventional PVI techniques. A total of 1005 patients undergoing radiofrequency catheter ablation (RFA) for AF were retrospectively analyzed in this study. The cohort was divided based on the ablation strategy: conventional PVI from February 2013 to September 2018, and HPSD-PVI from October 2018 onwards. The primary objective was to compare the predictors of ATA recurrence and the outcome between the two groups. Among 969 patients analyzed after exclusions, independent predictors of recurrence differed between groups; higher CHADS₂/CHA₂DS₂-VASc scores and lower left ventricular ejection fraction (LVEF) were significant in the HPSD-PVI group, while non-paroxysmal AF, larger left atrial volume index (LAVI), and longer AF history were predictors in the conventional PVI group. The HPSD-PVI group showed a trend toward lower ATA recurrence rates compared to the conventional PVI group in the propensity-score-matched (PSM) cohort (log-rank test, p = 0.06).

Accordingly, we aimed to evaluate the optimal cut-off values of the GNRI for cardiovascular events in patients with AMI.

The study was conducted using a single-center observational design.

Moreover, LA strain in 26 patients worsened after tafamidis administration, and multivariate logistic regression analysis showed age, global longitudinal strain and relative apical longitudinal strain index were identified as independent determinants of deterioration of LA strain after tafamidis administration.
